AI Thread Summary
A Physics Ph.D. can lead to various finance roles, primarily in quantitative analysis, but the specific area of physics studied is less important than programming and mathematical skills. Pursuing an MBA may offer better career prospects and higher salaries compared to a Ph.D. in physics, as the latter may not significantly enhance job opportunities in finance. Starting salaries for physics Ph.D. graduates in finance are around $120K, but trends indicate a potential decline in compensation. The finance career landscape is unpredictable, and while initial roles may be limited, there are opportunities for advancement based on experience and skills.

Since we're on the subject of the treatment of physics PhDs in various countries...how are things in Northern Europe? Say, Germany, Denmark, Finland, Sweden and Norway. What do the physics PhDs there do?

I hear that in India there are faculty openings at universities and what happens is they often hire Indians who went to the US/EU for their PhDs. I don't have any hard data to back this up but I know people who're looking at going down that road and have seen some fresh post-docs being hired by their alma mater. PhD in the States, post-doc there and in Europe/Israel and then assistant professorship. It's quite easy - just a question of going on the universities' webpages and clicking on the faculty pages.

It doesn't. Although you can see here too that the improvements from "really really bad" to "really bad" have been good enough to net 8% growth. India is ranked lower. It didn't copy the British. Post-independence India is actually a very interesting country, because it adopted the Soviet/PRC economic model while remaining a democracy with many of the British-era social freedoms. As it turns out, this didn't work better at producing GDP, though far fewer people ended up as victims of political murders and enslavement.

Adopting market economics would solve the more egregious problems (starvation, etc.) of every country, yes.

edit: the above post is somewhat different to what it was when I replied.

It's misleading to view there as being this "you" which is a single unified embodiment of a country, and of other countries. There's no difference in principle between a US company building a railway in a different part of the US, and a US company building a railway in Burundi, or a Burmese company building a railway in Guatemala. North Dakota isn't 'economically independent' but it isn't being 'held hostage' by California. Nor is any sufficiently small locality able to do almost any of that stuff for itself. In developed countries you get the opposite of 'economic independence': everyone is highly specialised, and as a result couldn't survive without everyone else, but it's actually better because they are able to perform their narrow specialism much more productively, and so is everyone else.

So why are there major differences in economic outcome across national borders? The bottom line is that in some countries it is illegal to make investments that would yield a return at the market rate, or the government would take too much for it to be worthwhile, or the other problem, which they have in Somalia, where the law is so weak that some random guy might come and kill you and take it. A market economy is just one where it's generally speaking legal to trade across borders, to trade with other individuals within your borders, and where some money you have today, you will still own next year.

The state could in principle do the same things. The problem is that it doesn't work in practice, and there are good theoretical economic reasons for that.

EDIT: Let's just agree to disagree. This is the career guidance forum and our off topic discussion has not helped anyone improve their academic or industrial careers.
I'm not sure. I find that a lot of physicists don't know much about economics and this gives them funny ideas about how the economy does/should work. That is very relevant for careers.

Not really. Solid evidence of the 20th century has been that market economies work, and command economies don't. The baffling thing is why people kept trying command economies despite all the failures, and even more so, why a lot of people still favour them today.

“There comes a time when you ought to start doing what you want. Take a job that you love. You will jump out of bed in the morning. I think you are out of your mind if you keep taking jobs that you don't like because you think it will look good on your resume. Isn't that a little like saving up sex for your old age?” - Warren Buffett

The other thing is *fundamental investing*. That's to figure out what fields generate real economic value.

Real businesses generate economic value. All that the banks have done to the US in the past 5 years is nearly send it bankrupt. Sure you can make huge money, but you can lose money too. IQ is correlated with income but not wealth http://thesocietypages.org/socimages/2008/02/06/correlations-of-iq-with-income-and-wealth/ . Using your intelligence to make money is easy, becoming wealthy is an art.

To inject some realpolitik, there is another type of "investing" too - running your own small business where 25% return on capital is not unusual. I've made money by running an IT consulting business. I was reading about somebody with 2 hotdog stands in New York making $120K, hard work and common sense is probably more important then IQ in making money. "The Millionare Next Door" has good insights on how average people can get wealthy, we don't all want to live in New York doing program trading https://www.amazon.com/dp/0671015206/?tag=pfamazon01-20 . And boy have I made some mistakes running my own businesses but I have learned a lot too, and you eventually get to the "lightbulb moment" of knowing how investing & running businesses really works, & to save money, invest wisely, and prosper.My point is do when you like, have a background plan to say make $1 million in 20 years. Do what you like in your 20s and aim to have $1 million by age 40 as your worst case scenario. You can be in the job you love and make money on the side as a hobby like I have done.

How would a Phd in physics give you an edge as a quant compared to someone who took a specialized course specifically dealing with the needs and requirments of being a quant?
I have a math degree & have tinkered around with mathematical finance out of interest. Having formally studied real analysis, complex analysis, numerical methods, engineering math, linear algebra etc then mathematical finance is just another textbook application to me. As a math graduate you get a "feel" for the functions, an armory your have learned in solving the math, built up from solving thousands of other math problems.

So when out of interest I wanted to develop personal software for delta neutral trading http://www.optiontradingpedia.com/delta_neutral_trading.htm I did it using knowledge of partial differential equations & numerical methods I have used in many other situations.

The same isn't true for somebody who "wants to be a quant", doesn't have a math background and uses rote learning to understand the math. Sure you learn the equations but without the deeper understanding a mathematician has.

Well guys, I am a finance major. I grew up with finance people. And I still talk with them about this same concept. The problem is your trying to chase the golden goose and EVERYONE is trying to do the same. The hedge fund count has exploded and so have the number of people with physics backgrounds trying to do the same thing as you. In fact, there are university programs now at schools like NYU that are tailoring programs in order to get the exact blend your talking about. These "quant farms" are already at the top of the trend and your competition is going to be just the same. Not that what your doing is impossible, it just has lost its nitch.
As far as trying to get the best education for the demand of the future? No one knows. Thats the next golden goose. And if everyone knew how to get there it wouldn't be the golden goose!
Most of what your talking about is number crunching and patterns. Assuming your going for short-tearm high-frequency investing what you need to be able to do is take a load of data. Find a general pattern. And prey to god the market conditions hold and the computer program has the right parameters.
People in this field also have a tendency to work very long hours. If you don't love the realm of long team unpredictable crap(longer than a week) like I do. I wouldn't sacrifice a solid steady career in physics. I know a nuclear engineer that makes USD$200,000+ a year and works 35 hours a week. Not bad. So the question then becomes. Whats ANY job that meets your Time to Pay equilibrium. I hate to be a naysayer but WallSt. realm is a total meet grinder. It will take you for all your worth and that's it. I would get the PHD as a back up!

In the case of non-public information, nothing can be done about that, since neither the general public nor universities for that matter (except to a limited number of researchers) have access to this.

That's wrong.

University researchers can and do have access to lots of non-public information which they can and should filter for public consumption. Let me give you a real example. I can't post here what the research that I'm doing, because I don't know that someone won't take that information and try to make money off the stock market. Even if it doesn't happen, the SEC will can get annoyed if I say something that can be interpreted as promoting a stock.

Now, what I *can* (and in fact do) do is to talk with people in local universities about what we are working on. I can do this because I know and trust the person that I'm talking to is not going to buy stocks with that information, and from the point of view of the SEC, I'm not making a "public offering." The reason I do this is so that the professor can then take that information and then adjust their course offerings to reflect what I've told them.

There is a lot of mathematical research that we are doing that we can't make publicly available. However, we do have a set of academics that are "white gloves." We feed them our mathematical research, they make some adjustments, and then they publish. Our name is not on the papers, and we and the regulators prefer it that way.

As far as filtering out poor information that is actually publicly available, there are ways to get around this problem, through the ranking of websites, investigating multiple sources of information, checking at references, cross-checking with Wikipedia (and the references they provide), etc. Granted, all of this is time-consuming, but it can be done.

But how do you know that you've got it right?

I'm not arguing that universities shouldn't give ANY advice (including good advice). What I'm stating is that universities (or more specifically, the professors and career counselling services who are currently employed at universities) should be more honest about the advice they are giving, which includes acknowledging their own limitations or lack of knowledge.

1) One thing that's fun is that often people don't know what they don't know.

2) I don't think that bad advice is the big problem. The bigger problem involves cultural biases. Yes you *could* go into industry, but you are a rotten nasty loser if you do it.

3) One thing that I found was that getting the skills that I needed to be productive in industry made me much less competitive when I applied for graduate schools. Because I was reading marketing books, I got "B"'s in classes that I could have gotten A's in, and that seriously hurt me when it came time go get into graduate school.

In this way, students will then have a means of weighing the advice they are given, and thus be able to make better decisions about the future, and the universities will thus ensure that they maintain their credibility.

I think that assumes that people are more autonomous than they actually are. One thing that I've found interesting is that one big trick that sales people do is to give people the illusion of choice. Sales people can't point a gun at your head and force you to buy a car, but they have a lot of psychological tricks that they use to push you in that direction.

First of all, is it the case that universities in the US do not pay taxes? Certainly each individual professors and staff members pay income tax, and I thought that businesses owned and operated by the universities pay taxes as well.

Non-profit universities do not pay tax. If the universities owns a for-profit business that's taxable.

Anyways, if in fact universities do not pay taxes is immaterial to me, because universities do work for the public good, in terms of providing higher education and providing high quality research.

But by working for the public good, you are subject to higher standards. If I go to buy a car, I know that the salesman is not acting in my interests, and if the salesman lies to me and convinces me to buy the car, to some extent, it's my fault since I should have known not to trust a car salesman completely.

Because universities are supposed to work for the public good, there are higher standards. The difficulty is that universities have "private interests." Universities are businesses and they are under pressure to increase tuition. If you go to a car salesman, and ask "do I really need this car?" the salesman will say *absolutely* and then pull out every psychological trick that they can to get you to sign on the dotted line.

The difficulty for universities is that they are also under similar pressures, but the rules are different for public institutions. That means that if the provided bad advice in the past, you just can't say "your fault." You can't change the past, but having people say "I'm sorry we screwed up, what can we do to make it not happen again?" would help. I don't hear people saying that.

First of all, universities are only one of many factors behind economic growth; an important factor, but only one factor. Second, university budgets in the US are the responsibility of individual states, and their budgets (along with many other state programs) are being cut as a consequence of the budget crises affecting the states, due in no small part to state constitutions mandating a balanced budget and banning deficits.

1) It's a critical factor

2) University budgets are the responsibility of the individual states, but most of the money is Federal. State constitutions mandate balanced budgets, but there is this big loophole that states receive Federal transfer payments, and if you look at where the money ultimately comes from, it's mostly Federal.

If you really want to stop university budgets from getting cut, then the only meaningful thing that can be done is for the federal government to bail out the state governments.

Well, yeah...

But what you can do is to hold enough protests at the state level to stop cuts, that the state legislatures are forced to beg for money from the Federal government. If the state legislatures can balance their budgets by cutting state universities, they will. Whoever screams least gets cut. If you scream at the state legislatures not to do that, then the numbers won't match, so they'll have to go to the Federal government. At which point you play the game in Congress. The Federal government can do two things that state governments can't. It can run deficits and print money.

One person can't do much, but one person in an organized system can do a lot.

However, it is worth keeping in mind that many vocational training is provided by community colleges.

Which are being cut by state governments. One good thing about community colleges is that getting a two-year degree from a CC is often a stepping stone to a four year degree at a local public university.

Now what I'd like to see is to see an alliance between MIT and community colleges. Personally, I think it's a mistake for MIT to focus on creating a distance education partnership with Harvard. The institution that MIT really should reach out to is Roxbury Community College. One thing that RCC can provide is vocational training so that physics Ph.D.'s don't starve once they get their degree.

University degrees do provide "social capital" but social capital on its own does not mean all that much unless if it directly leads to meaningful employment.

But it does. If you know someone that works in a major bank, they can give you the e-mail of someone that you can send your resume to with a reasonable assurance that someone will at least read the resume. If you hang around managers, HR people, and CEO's, you figure out how they think and that gets you in the door.

Furthermore, I feel that the stigma associated with vocational training in the US is unproductive, since there is a demand in the US for skilled labor. Combined with the currently high unemployment rate, perhaps we should be re-assessing the value of vocational training.

The trouble is that when there is a high unemployment rate, the knives come out. If there are N job openings and 1.1 N job seekers then increasing training is just going to make the problem worse.

One problem with increasing training is that you end up with the Ph.D. problem. If we train 100,000 air conditioning repair men then you will likely end up with 90,000 unemployed air conditioning repair men who are worse off because they have debt.

[QOTE]You are assuming here that China will continue to maintain their impressive rates of economic growth, which is far from guaranteed[/QUOTE]

People in China are looking ahead and seeing problems and they are dealing with them. There are limits to China's current growth model, and it is going to hit them in the next few years. That's why people are working *NOW* to start fixing the problems so that you don't end up with an economic crisis in ten to twenty years.

The general belief in China is that long term, China needs to move into science and technology. This is going to take two to three decades to do, which is why people are starting *NOW*.

The thing about China is that it has a plan. It may be a bad plan, but people are thinking about what the Chinese economy is going to look like in 2050, and it's going to have a lot of science and technology. What worries me about the US, is that no one is even thinking about 2050. I haven't even heard people talk about 2020. This is bad for science. If your time horizon is two years, then science is a waste of money. If your time horizon is fifty years, then it's stupid to cut science now.

The good news for the US is that it has such a good science infrastructure that it's going to take a decade of incompetence to destroy it. People are being stupid now, but there is still lots of time to stop it before things get bad.

Furthermore, young people's higher approval of China is directly linked to the nation's ability to deliver on employment. Once that changes, I envision that public opinion will very quickly sour, and given the repressive nature of the regime, things could get very ugly very quickly, as is already evident in the number of protests in rural areas against land seizures (and these are protests that have been publicly reported).

So rather than sit back and let things fall apart, the government is actually *doing stuff*. If you have lots of unemployed people, they start getting angry and demonstrating. So what can we get them to do to avoid that. Well, there are some railroads to be built.

Employment is essential to keep the government in power, so the government is moving heaven and Earth to get people jobs.

China is currently able to flood money in science and technology because they have large reserves of cash (primarily due to the tendency of the average Chinese to save money in state-owned banks, which is due in no small part to insecurity brought on by lack of property rights). Once the Chinese economy will transition to a more consumer-based economy, that large reserve of cash will start to diminish, and China's ability to spend will become more constricted.

So maybe it's not such a good idea to move to a consumer-based economy. Singapore has high savings rates, and if through science and technology you can maintain high growth rates, you can keep saving massive amounts of money.

Savings -> science -> technology -> productivity -> more savings

The big limit is when people get old and start withdrawing their savings. How do you keep productivity with fewer workers. Science to the rescue!

Before one can even begin to organize and hold protests, or act, one needs to know what they are protesting for or against, and that begins by asking questions first. It's the act of questioning that serves as an impetus for action.

Sometimes you don't. There's something to be said for saying "we are angry, we just want results, you are the people in power, you figure out how to get us stuff." Getting people to think too much is "psychology trick #2343" for making sure that nothing happens.

Singapore has minimal institutional similarity to PRC. It's even more of a free market than the West. It's essentially 1930s Britain projected into a future where the actual Britain had taken a different fork instead of voting for a Labour landslide in 1945. The same really is true of HK, but PRC does at least now own HK. My point is the best case scenario is that, in GDP per capita terms, HK:PRC::NYC:USA, and since PRC assumed control the economy of HK has grown at ~3% annually in real terms.

With enough time, you can make large institutional changes. For a developed economy, 3% is outstanding. The question for a developed economy is whether you want 0% without technology or 3% with technology. Historically three percent growth is huge. That was the average growth rate of the industrial revolution.

Over a lifetime, 1% growth means 2x wealth, whereas 3% growth means 8x. Chinese growth rates are going down, and the question is whether they are going to stabilize at 3% or 0%, and to get 3%, you need science and technology.

I agree HSR is more useful than making a lot of steel and burying it. The question is, is it the best use of resources possible? I don't know.

Does it really matter?

The trouble with getting into arguments over what is "best" is that it's an excuse to do nothing.

So maybe HSR is good for China, or maybe not, but governments are often mistaken about things, because it seems to be impossible to centralise information in massive bureaucracies and use it effectively.

BTW, I've read Von Mises, and know about the socialist calculation problem. I actually agree with a lot of stuff that he says, but I think he gets some things critically wrong.

There are some things that governments are horrible at. Some things that governments are good at. In any event, the government in 2007 realized that if it didn't generate employment and fast, it would be faced with what happened in Egypt, so the government went and asked what project would keep people too busy to demonstrate, and if it produces economic value, that's a nice side effect.

Government projects don't 'create jobs', they move them from what the private sector wants to do to what the state wants to do.

No, they move people from "unemployed" to "working." It may be acceptable for the private sector to have lots of people doing nothing, but in China having lots of unemployed people means mass protests, and so it's unacceptable. One reason that the US has higher unemployment than China is that US political system can tolerate 8% unemployment indefinitely without a revolution. China can't.

That's the key issue. It's not that research is bad, but it's a secondary effect, something you get when you're rich because you don't need to focus all resources on survival, and can instead do something charitable for the world in 20, 30 years time. Or maybe not.

The thing about survival is that it's not good enough for most people. No one in the US need to starve and the biggest problem with poor people is obesity and not malnutrition. If you like the way things are, and don't see any need for making things better, faster, cheaper then there really isn't that much need for science.

The thing about China is that it's no longer in starvation mode. The last famine in China was in 1973. So if Chinese people were merely content with "not starving" then you don't need to do anything else. But people aren't content with that. People want more stuff, and for that you need constant economic growth.

China's current growth model is going to hit a wall around 2020. Since the government wants to stay in power past 2020, people are trying to figure out what is going to work. Part of the reason people are worried NOW is that the first plans are going to fail.

Just to be clear, I'm not worried about the United States collapsing economically. What I am worried about is that the US turns into Japan, and loses the "frontier spirit".

I think it's a *lot* more complicated than that. One problem with "market rate" is that you have to have a market, and getting one is non-trivial. One problem is that people sort of assume that if you don't have a "free market" system then you have a Stalinist system when in fact there are other possibilities.

The state could in principle do the same things. The problem is that it doesn't work in practice, and there are good theoretical economic reasons for that.

I find that most theoretical economists just end up formalize how they think the world should work rather than looking at how it really does work.

A "hands off" policy toward the banking system also doesn't work. The trouble is that the state is the ultimate guarantor of the banking system, so if the state isn't heavily involved at regulating the system, what people will do is to make "head I win, tails the state loses" bets.

Now in principle, you could have things work with a "no bailout" policy. The trouble with that is that you can set up a situation in which "no bailout=the world blows up". At that point the state is forced to do a bailout. The trouble is that if people know that the state is going to to a bailout you get back to the previous situation. You *say* that you aren't going to bail me out, but I don't believe you.

Not really. Solid evidence of the 20th century has been that market economies work, and command economies don't.

Not so clear. The Soviet economy seemed to work very, very well in the 1950's. It fell apart around 1970. Now *why* it fell apart is an interesting question. I would argue for Vladimir Popov's model in which the Soviet Union stopped infrastructure investment in the 1950's.

Essentially, the trouble was that because Soviet planning was based on production quotas rather than profit, there was strong disincentive to replacing aging machinery. You lost your quota, and there was no way of calculating the economic benefit of the new machines. This didn't matter in 1950, because the Soviets had to repair everything because of WWII, but it started to kill the economy in the 1970's. If that's the explanation, then it's going to be pretty bad for the US (however, unlike the Soviet Union, the US has a strong enough political system to prevent total collapse).

The baffling thing is why people kept trying command economies despite all the failures, and even more so, why a lot of people still favour them today.

Because no one arguing for a Soviet command economy. One thing about China was that since 1950, "Soviet=bad" so that in the late 1970's, there was strong resistance to reinstituting Soviet style economic planning. One thing about Soviet economic planning is that it requires something like a Josef Stalin, and the Communist Party in 1980 (or now) simply does not have that sort of power or economic unity.

Having some central planner order a factory to produce 500 locomotives just will not work well for the reasons that von Mises and Kornai pointed out. Now what I think will work is to have a pricing system in which you reflect economic costs. So a government bureaucrat looks at the cost of 500 locomotives and can compare that with the price of say 10 aircraft carriers. By changing tax rates and purchasing things at market prices rather than forcing people to build them, you get around the socialist calculation problem.

There are some similarities between the Chinese economy and the theories of Oskar Lange. It's not a concidence since there was a lot of Eastern European influence in Chinese thinking circa 1980.

I used to wonder why people clung to Soviet models after it seemed obvious that they wouldn't work. Then I see people cling to neo-liberal economic ideas after it is pretty clear at least to me that there is something seriously wrong with them, and it makes more sense. One issue is that you can't replay history, so when the Soviet model fails, you can try to argue that there wasn't enough "real communism", and I've seen similar arguments that things fell apart because we don't have "real markets." You can get into large arguments over this, but the counterargument that I find convincing is a political one. If you can't realistically have "perfect communism" then it's pointless to argue about whether it is a good thing. Similarly if you can't have "perfect capitalism" then it's pointless to argue that it's a good thing.

One problem is the idea that if you oppose X you must support Y. I think that Soviet economic planning doesn't work, but Chinese style economic planning works in China (whether it would work or not in the US, I don't know, and I doubt it).

I think your idea of usefulness is very contrived. Earth scientists, chemists, and environmental/chemical/mechanical engineers also write models of diffusive phenomena. What is special about astrophysics that makes for better model writers?

Astrophysical simulations use a lot more compute power than most engineering simulations. Also most engineering simulations can be done with "canned programs". Essentially the equations are the same from situation to situation whereas the boundary conditions are different.

In oil/gas and finance it's the opposite. The boundary conditions are trivial whereas the dynamics changes.

I think that China lost to Japan because Japan had more of a Western market economy, and Japan lost to US because US had more of a Western market economy.

So how did Russia win? One reason people in China were attracted to the Soviet model in the 1950's was watching the Russians just annihilate the Japanese army. Gee. Wish we could do that...

In principle China could have had the same productivity per worker as the US, with no indigenous scientific contributions required, and built 50 aircraft carriers and 200,000 aircraft and squashed Japan.

Don't think so. Aircraft was invented in 1903, and you just can't copy an aircraft carrier or build aircraft factories. It's actually both sad and enlightening to see the problems China has now trying to build civil aircraft and aircraft carriers. It's pretty clear that Chinese civil aircraft manufacturers and military shipyards are pretty clueless. But if you don't try to build a rotten airplane, you'll never build a good one.

There's also the little matter of whether other countries will let you copy their stuff. I'm sure that China would love to have the latest designs for American aircraft carriers. One big reason China is working on high-speed rail rather than aircraft is that most countries are much less annoyed when you copy their railroad designs than if you copy aircraft designs, because there are fewer military applications.

It didn't because it was ruled by first monarchists, then nationalists and socialists, who all thought that command economies were good.

Because of Russia. Also, if you are in a life and death struggle for national survival, you can make the argument that command economies are good. Militaries are not run on market principles, and one way of thinking of China in 1940 was to imagine the entire population being one big army. This also happened in the United States. Once you are on a war footing, then you have price controls and rationing.

Now you can argue that people in 1950 were mistaken, because once Russia got to 1970, things fell apart. But one wonders if the same thing is happening to the "capitalist model". I can imagine someone in 2020 looking at the "neo-liberalism" the same way that people in 1995 looks at communism.

There's also generational issues. The Cold War was an important part of my childhood, and the fall of the Soviet Union was one of the important defining events of my youth. So it's interesting to know that people in college today didn't experience that and their view of the world is likely to be quite different because there are things in my memory that aren't in theirs.

So does much of Hong Kong. Hong Kong is "central planning done right." The HK leaves some things to the market, but it is extremely intrusive in other things (such as health care where HK copied the British model). There are some areas (land policy) where you see the PRC copying Hong Kong.

The Singapore government is also pretty intrusive with things like Temasek holdings.

The trouble is that when there is a high unemployment rate, the knives come out. If there are N job openings and 1.1 N job seekers then increasing training is just going to make the problem worse.

One problem with increasing training is that you end up with the Ph.D. problem. If we train 100,000 air conditioning repair men then you will likely end up with 90,000 unemployed air conditioning repair men who are worse off because they have debt.

The problem that the US is currently experiencing is not just a high unemployment rate, but also a mismatch between the skills currently possessed by those who are unemployed (or not yet employed) and those jobs that are currently in demand as of this moment. (There's also a problem with mobility of workers, which for the moment I will not address)

The situation we're facing is that there are N job openings, but out of the 1.1N job seekers, only, say, 1.1N/10 = 0.11N of them would possesses the necessary skills or qualifications to actually be even hireable. Therefore, many of these N jobs end up being unfilled even though you have a large pool of job seekers.

So given that situation, wouldn't it make economic sense to provide some form of vocational training to reduce the mismatch and ensure that more of the N jobs end up being filled? I would argue yes.


So rather than sit back and let things fall apart, the government is actually *doing stuff*. If you have lots of unemployed people, they start getting angry and demonstrating. So what can we get them to do to avoid that. Well, there are some railroads to be built.

Employment is essential to keep the government in power, so the government is moving heaven and Earth to get people jobs.

I agree that China is indeed "doing stuff" to avoid the scenario of masses of unemployed people causing problems. All I'm stating is that there may be limits to China's ability to provide the levels of growth to ensure low unemployment, especially if their reserves of cash will diminish or the rest of the world economy goes into recession (a very real possibility given the problems with the Eurozone).

So maybe it's not such a good idea to move to a consumer-based economy. Singapore has high savings rates, and if through science and technology you can maintain high growth rates, you can keep saving massive amounts of money.

Savings -> science -> technology -> productivity -> more savings

The big limit is when people get old and start withdrawing their savings. How do you keep productivity with fewer workers. Science to the rescue!

First of all, Singapore has high savings rates because the vast majority Singaporeans do not own any property (given the lack of land in an island-state like Singapore, that shouldn't be all that surprising). And the high economic growth rates in Singapore is not based primarily due to investments in science and technology, but more due to its unique position as a trading hub with the rest of Southeast Asia, and by extension the rest of East Asia (access to cheap labour from nearby countries such as Indonesia and the Philippines is a notable contributor as well, along with high immigration rates).

On your other point, China as of this moment is already transitioning into a consumer-based economy (as it inevitably would given the growth of the middle class), so it is only inevitable that savings rates will diminish. This will only accelerate given the rapid aging of the Chinese population (due in no small part to the one-child policy).

Agreeing with Statguy2000.

Singapore's wealth in the main, came from a) the location of its seaport, b) banking, c) a benevolent dictatorship that was able to implement long term plans. Sings in general don't want to be scientists. They want to be lawyers, doctors and bankers. "Why you want to be scientist? No money lah". These days it's a retail trade hub too, but that's more a side effect of the first 3.

Saving rates are generally higher in Asian cultures than western. In the case of Singapore, being left with nothing is almost taboo. The government doesn't admit that truly homeless people exist - their official line is "homeless are that way by choice". The HDB system (public housing) doesn't cover everyone. There's 2 population figures. One includes migrant workers of which they have a gigantic amount all living in camps (and probably homeless, I don't know). The other doesn't.

China isn't really communist in the traditional sense of the word.

What concerns American businesses (financially as opposed to ideologically) is not Chinese communism, but Chinese capitalism and the value of their currency.

In the third world, Chinese are using a start-up type model, similar to how Silicon Valley works: small companies of about 3 guys, iterate your product, build as you go. It's much more agile than the traditional method of entering with a megacorp, paying your R&D upfront, and starting with a complete product. As a result, this agility means China is much more able to sieze opportunties in the developing world, such as Africa and Brazil, and this helps to explain their growing influence. Having a sort of command economy also helps as it can focus on long term issues; it's quite hard to get people to vote for a 25 year plan run by a 5 year government.

IOO China has too much saved up and "should" really spend some of that on social programs. I can't remember what they have. it's something like USD 3 trillion in reserves? They will spend it but I'm not sure they have decided how best to go about it. That's not really something I know much about. (*)

As you say, China's got a huge problem with population age. Recently passed/thinking of passing a law that requries children to care for their parents, after the parent reaches a certain age. Don't know if that came to pass or not.

(*) What they will do with the money.

That statistic is not incompatible with StatGuy2000's statement. Just need more people per household (which they do have).

If we train people to have useful skills, businesses will use them. particularly businesses facing a skills shortage.

Yes, of course, I was questioning the point that it's "more of a free market". I think it shows that one can have both free market and socialist elements, such as good government housing, side by side. The underlying conception may be that free-market versus socialism is not always a useful "degree of freedom".

Isn't it generally more of a free market though? Its economic freedom rank is 2nd in the world, according to the Heritage Foundation:

That is a very interesting number indeed. I guess I was simply making the point that the Heritage Foundation itself makes: "State ownership and involvement in key sectors remains substantial. A government statutory entity, the Central Provident Fund, administers public housing, health care, and various other programs, and public debt is over 90 percent of GDP."

Every country has elements of both, but it's a matter of degree, and the more free market less socialistic countries generally do better.

I gather than in the US, socialism is a very bad and extreme word that even its supporters don't like attached to them. This is not the case in Britain, so apologies if what I say seems overly polemical to you.Twofish - that is an awful lot of replies, so I can't promise I'll reply to all of it.

With enough time, you can make large institutional changes. For a developed economy, 3% is outstanding. The question for a developed economy is whether you want 0% without technology or 3% with technology.
I don't think that that is the choice or anything like it. If you disagree, do you have any empirical reason, or is it just a feeling?

My argument has been that basic research is not excludable, ie. everyone gets it, and soon everyone benefits. For instance, the man who developed the world wide web was British, and working in Switzerland. Did this mean that the WWW was localised in either of those places for some time, with no one else getting the benefit? Countries adopted internet largely in line with how open their institutions in general were to investors coming along and building new infrastructure to make a profit, and where people were already wealthy enough to take advantage of it.

So I think the choice is more like, if the world as a whole invests a lot in basic research, the world as a whole might get 2% growth. If not, 1.5% growth.

Does it really matter?

The trouble with getting into arguments over what is "best" is that it's an excuse to do nothing.
It does matter, because if due to inefficient allocation the return on investment is 2% less than it should be maybe that really will wipe out GDP growth.

BTW, I've read Von Mises, and know about the socialist calculation problem. I actually agree with a lot of stuff that he says, but I think he gets some things critically wrong.
Mises is historically interesting and more right than most at that time, but the more modern economics is good too. Look up neoclassical growth models and 'conditional convergence'. Also public choice theory, if you are interested in governments and how they allocate resources.

No, they move people from "unemployed" to "working." It may be acceptable for the private sector to have lots of people doing nothing, but in China having lots of unemployed people means mass protests, and so it's unacceptable. One reason that the US has higher unemployment than China is that US political system can tolerate 8% unemployment indefinitely without a revolution. China can't.
The empirical evidence for this effect is weak.

(I'm actually amazed Obama made falsifiable predictions, as he is usually a competent politician. Probably some adviser got fired for this.)

Now in principle, you could have things work with a "no bailout" policy. The trouble with that is that you can set up a situation in which "no bailout=the world blows up". At that point the state is forced to do a bailout. The trouble is that if people know that the state is going to to a bailout you get back to the previous situation. You *say* that you aren't going to bail me out, but I don't believe you.
To play devil's advocate, maybe it is good if the world blows up. Recently everyone has decided that more regulation is needed because banks are too reckless. Well if everyone's savings and pensions were wiped out, I'd bet that banks would get a whole lot less reckless very quickly. I wouldn't be surprised if a lot of people started holding a substantial fraction of their savings in gold bars in a safe deposit box. So this sort of thing is a result, not exactly of socialism, but of government interventionism certainly. I agree that politically this is infeasible, but politics is not part of the free market.

Not so clear. The Soviet economy seemed to work very, very well in the 1950's. It fell apart around 1970. Now *why* it fell apart is an interesting question. I would argue for Vladimir Popov's model in which the Soviet Union stopped infrastructure investment in the 1950's.

Essentially, the trouble was that because Soviet planning was based on production quotas rather than profit, there was strong disincentive to replacing aging machinery. You lost your quota, and there was no way of calculating the economic benefit of the new machines. This didn't matter in 1950, because the Soviets had to repair everything because of WWII, but it started to kill the economy in the 1970's. If that's the explanation, then it's going to be pretty bad for the US (however, unlike the Soviet Union, the US has a strong enough political system to prevent total collapse).
I think this is plausible, because nationalisation killed a lot of British industry in the same way. But that's the whole problem: nationalised industries respond to political pressures and if there's no internal market it's more or less impossible to make any comparison in value beyond the very most basic ("10,000t of steel is better than 5,000t of steel" - at least until people start messing with the definition of steel). If you favour a nationalised investment fund that just investments money in the market like anyone else, then that's a lot less damaging.

Note that places like Singapore having big sovereign wealth funds is often a symptom of them being more free market than places like the US. This is because it means they fund their state pensions and unemployment insurance schemes via investing the contributions. In the US and Europe, these things are still controlled by the state but the contributions are spent immediately and the benefits are paid for using inter-generational transfers and debt.

I used to wonder why people clung to Soviet models after it seemed obvious that they wouldn't work. Then I see people cling to neo-liberal economic ideas after it is pretty clear at least to me that there is something seriously wrong with them, and it makes more sense. One issue is that you can't replay history, so when the Soviet model fails, you can try to argue that there wasn't enough "real communism", and I've seen similar arguments that things fell apart because we don't have "real markets." You can get into large arguments over this, but the counterargument that I find convincing is a political one. If you can't realistically have "perfect communism" then it's pointless to argue about whether it is a good thing. Similarly if you can't have "perfect capitalism" then it's pointless to argue that it's a good thing.
We can at least say that, while both are flawed, the fake-markets have worked a lot better than the fake-communism. I'm open to the possibility there is some better system than markets, but it's not any of the ones I've heard of, and most of the improvements I can think of involve moving more toward markets.

So how did Russia win? One reason people in China were attracted to the Soviet model in the 1950's was watching the Russians just annihilate the Japanese army. Gee. Wish we could do that...
What do you think the US would have done to it? Or even the Germans, another command economy, who were inflicting 3:1 casualty ratio on the USSR even as they were retreating everywhere throughout 1944. The Japanese army in Manchuria would have been squashed by any of the great powers, because it had hardly any tanks or aircraft. Production had been diverted to the navy and airforce long before.

Don't think so. Aircraft was invented in 1903, and you just can't copy an aircraft carrier or build aircraft factories. It's actually both sad and enlightening to see the problems China has now trying to build civil aircraft and aircraft carriers. It's pretty clear that Chinese civil aircraft manufacturers and military shipyards are pretty clueless. But if you don't try to build a rotten airplane, you'll never build a good one.

There's also the little matter of whether other countries will let you copy their stuff. I'm sure that China would love to have the latest designs for American aircraft carriers. One big reason China is working on high-speed rail rather than aircraft is that most countries are much less annoyed when you copy their railroad designs than if you copy aircraft designs, because there are fewer military applications.
I agree it couldn't have happened 1936-1937, but 1911-1937 is a long time. The misleading thing is to think like an engineer. To an engineer, what matters is if you have the plans to build an aircraft carrier, and then if you have enough steel, and then skilled people who can make steel. But this is more of a management question. If you've got good institutions that are getting everyone to do profit-maximising jobs, soon you're going to be rich and can just pay people to learn those things or buy engineers from abroad who know how to build aircraft carriers. Most of the Japanese ships that defeated the Russians in 1905 were built in, then designed in, then just partially equipped by Britain, and orders were given in English. But Japan still ended up owning Port Arthur, not Britain.

In 1911, no one could build an aircraft carrier because no one knew what an aircraft carrier was.

Because of Russia. Also, if you are in a life and death struggle for national survival, you can make the argument that command economies are good. Militaries are not run on market principles, and one way of thinking of China in 1940 was to imagine the entire population being one big army. This also happened in the United States. Once you are on a war footing, then you have price controls and rationing.
Maybe, but it still matters how rich you are when you start this. If you take US economy of 1941 and convert everything for war, you can make a lot more war materiel than if you take the Japanese economy of 1941 and convert everything for war. The advantage for a centralised society if you can convert for war in, say, 1931, and then you can win against a stronger opponent for the first 12 months, until they can sort themselves out.

Now you can argue that people in 1950 were mistaken, because once Russia got to 1970, things fell apart. But one wonders if the same thing is happening to the "capitalist model". I can imagine someone in 2020 looking at the "neo-liberalism" the same way that people in 1995 looks at communism.
Problem is that it's mroe like people were more delusional in 1950. Here are two graphs from Maddison:

Two interesting things:

1. USSR never gets close to the USA
2. USSR's temporary improvement comes because of slower than usual US growth, not faster than usual USSR growth

Astrophysical simulations use a lot more compute power than most engineering simulations. Also most engineering simulations can be done with "canned programs". Essentially the equations are the same from situation to situation whereas the boundary conditions are different.

In oil/gas and finance it's the opposite. The boundary conditions are trivial whereas the dynamics changes.

Thank you. I remember you saying before that in astrophysics that the dynamics change frequently, and the boundary conditions are trivial, whereas in say, engine design or pollution modeling, the dynamics stay roughly the same and complicated boundary conditions are the problem. Can you give examples of the equations *changing*?

Sure.

Contract A: I lend you X dollars, tomorrow you pay me back Y0 dollars, then next day I lend you X1 dollars. The next day you let me back Y1 dollars. We do this for six months and at the end up pay me Y dollars. Let's suppose with interest the intermediate cash flows are zero.

Contract B: Now let's suppose I lend you X dollars and you lend me back Y dollars in six months.

OK, since the intermediate cash flows are zero A and B are mathematically identical, and worth exactly the same. That is... Until 2008.

The rules changed. The thing is that if I lend you money for one day, and you look like you are going to go broke, I stop lending you money in contract A. Since you have my money in contract B, I can't stop lending money. So what you end up with is that since 2008, Contracts A and B have different values, so one thing that physics Ph.D.'s try to do is to come up with equations that describe the new relationships between A and B.

Another example:

I have a contract with you, that says that I loan you X dollars in exchange you deposit Y dollars as collateral. If certain events happen (i.e. SP500 goes below value Z), you will be required to put up more collateral. Now I have two contracts. Contract A says that you have to put up the new money in dollars. Contract B says that you have to put up the new money in either dollars or euros. Now before 2008, the difference in value between contract A and B was negligible, because people didn't think much about what happens when companies go broke. They aren't now, and contracts A and B are worth very different amounts

(Quick question on an interview: which contracts are worth more?)

Now I don't want to imply that *only* astrophysicists study these things. If some ocean physicists says "hey, we study that too" I would be tickled pink. I'm not an ocean physicist, but I'm sure that they study something that would be useful to me.

And I disagree. Even to *copy* technology requires a non-trivial amount of science and technology skill. People in China benefit a lot more from the WWW than people in say Haiti, because China has institutions that can take advantage of that, and Haiti doesn't. One reason China is spending money on railroads rather than airplanes is that trains are easier to copy than airplanes, and China doesn't have the skill to copy civil aircraft.

The other point is that for basic research to be useful you need a good entrepreneurial economy. If basic research *alone* could create prosperity, then the Soviet Union would never have fell. Russia had excellent basic research, it also had no mechanism for converting that research into economic growth.

For instance, the man who developed the world wide web was British, and working in Switzerland. Did this mean that the WWW was localised in either of those places for some time, with no one else getting the benefit? Countries adopted internet largely in line with how open their institutions in general were to investors coming along and building new infrastructure to make a profit, and where people were already wealthy enough to take advantage of it.

In looking out how places do and don't benefit from technology, it's better to look at regions rather than countries. Cuprertino, California and Austin, Texas benefited from the web a lot more than Detroit, Michigan or Jackson, Mississippi. Also a lot of the financial networks are regional. For example, if you have a great idea in Cuppertino, you rather easily find people to fund it. This isn't true in Detroit.

One reason for looking at regions is that you can better see the processes. I don't think that you say that Detroit is less "free market" than Cuppertino. You can point to some specific aspects. Such as non-compete clauses.

So I think the choice is more like, if the world as a whole invests a lot in basic research, the world as a whole might get 2% growth. If not, 1.5% growth.

And that's ***HUGE****!

It's the difference between 3.4x growth over 100 years and 6.24x growth.

This also explains why people were so ga-ga over the Soviets. During the industry revolution, the typical growth rate was 3%. The Soviets in the 1950's were able to get 6%, that is totally un-freaking-precedented historically. Now the US was able to do a lot better and the Soviets hit a wall. But if you look at typical growth rates from 1870 to 1950 then it's not surprising that people thought that the Soviets had found salvation.

Look up neoclassical growth models and 'conditional convergence'. Also public choice theory, if you are interested in governments and how they allocate resources.

Yup. I know about the Solow growth model. The thing about technology is that it changes both the returns on capital and the amount of technology depreciation. The thing about public choice theory is that who governments allocate resources depends on the institutional context. In the case of China for example, you have state-owned enterprises, but the heads of the SOE's are rewarded based on the profit that they make, which leads to a different set of behaviors if you have a different set of institutional incentives.

The way that I view things is

institutional framework -> human incentives -> mathematical model that describes those incentives.

To play devil's advocate, maybe it is good if the world blows up.

1) The problem is that if the world blows up, then there are no incentives for "good" behavior. You have two banks, one in which the people are "with clue" and do good risk management. One in which people are idiots and then have horrible risk management. Bank B blows up the world. This puts people in Bank A out of a job. Now if you know that this is going to happen, then the rational thing to do is to just get as much money as you can and go nuts. What's the point in being "good" if you are dead whatever you do?

2) The government just will not let the world blow up, and if they say that they will, no one will believe them. You saw this with Freddie and Fannie. Everyone know that they would get bailed out, so their securities would be priced as if they were government backed.

Well if everyone's savings and pensions were wiped out, I'd bet that banks would get a whole lot less reckless very quickly.

If *everyone's* savings were wiped out, then people would get a lot *more* reckless. Again, what's the point in being "good" if you are going to suffer for it? What's the point in saving anything if you know it's going to get wiped out. I mean, if there are no consequences, then the rational thing to do is to take every cent I have and blow it on hookers and cocaine.

Also putting it into gold in safety deposit boxes doesn't work. If things get really bad, they you won't be able to trust the people holding the boxes, and if you try to keep the gold yourself, you'll end up being prey to thieves.

We actually saw this in Russia and Latin America. Also "trust" explains a lot of things about the Chinese economy. One reason that people buy real estate is that it's tough to steal a house. It's not hard to steal things *in* a house, but it's hard to steal a house. Whereas with a stock all you have is a piece of paper.

I wouldn't be surprised if a lot of people started holding a substantial fraction of their savings in gold bars in a safe deposit box.

Yup. You see this where people start holding dollars. The trouble is that this makes economic transfers much. much more inefficient, and if things get bad enough, even that's not going to work. If things break down enough, who is going to protect your gold? The police? HA... They'll be first in line to steal it.

At which point you are stuck. You don't have the institutions for saving, which means no economic growth which means no institutions for saving.

Note that places like Singapore having big sovereign wealth funds is often a symptom of them being more free market than places like the US. This is because it means they fund their state pensions and unemployment insurance schemes via investing the contributions. In the US and Europe, these things are still controlled by the state but the contributions are spent immediately and the benefits are paid for using inter-generational transfers and debt.

I don't think it's useful to classify things into more free market or less free market. For example, in China, you argue that non-state pension funds are better because they are more socialist.

The other thing is that the US Federal government has a huge amount of money in the Social Security Trust fund, and theoretically it could invest that money in the stock market. The reason that it doesn't has to do with the fact that people in the United States don't think that the government should own industries, whereas people in France or China are less resistant to that idea.

We can at least say that, while both are flawed, the fake-markets have worked a lot better than the fake-communism. I'm open to the possibility there is some better system than markets, but it's not any of the ones I've heard of, and most of the improvements I can think of involve moving more toward markets.

The central role of markets is something that is not under serious question. The question involves how do you structure and regulate markets. Most of the changes that I've seen have been to fix the obvious "bad incentives" that you find in markets.

But this is more of a management question. If you've got good institutions that are getting everyone to do profit-maximising jobs, soon you're going to be rich and can just pay people to learn those things or buy engineers from abroad who know how to build aircraft carriers.

You can have rich people, but a government that is starved for money. If the government doesn't have money, you don't have an army, and once you don't have an army, other people come with their armies and take your wealth. You can be lucky like the United States and not worry about that, but China had less lucky geography.

I agree that good institutions are important, but then we get tauntological. Good institutions produce wealth. Producing wealth is the definition of good institutions. That doesn't tell me anything useful.

Two interesting things:
1. USSR never gets close to the USA
2. USSR's temporary improvement comes because of slower than usual US growth, not faster than usual USSR growth

Cut the graph off in 1960, and the USSR looks very impressive. One could argue that the growth in the 1960's and 1990's was due to investments in science and technology and that if the US didn't respond to Sputnik that there would have been less GDP growth. Or maybe not.

The other thing is where you start the graph. If you go back to 1925 and start it with the Great Depression, then the USSR looks outstanding.

One fun game to play is "stop the clock". You stop the clock at a point in time and then see how the world looks. If you "stop the clock" in 1965, then you see Soviet growth rates starting to trend down and US growth rates starting to trend up, but in 1965 you have no way of knowing if this was a "blip" or a permanent trend.

Now it wasn't until the mid-1970's, when people realized that this *wasn't* a blip, and then you give it another ten years for the bureaucracies to start responding, at which point you are with Gorbachev.

The reason that "stop the clock" is a fun and scary game is that you realize that people in 1965 who saw Soviet style planning as the wave of the future weren't idiots. Based on the data that they had, that was a reasonable conclusion. Now it looks idiotic from the point of view of 1990. But one reason I'm not to harsh on people in the past, is that I'm sure there will be something that people in 2030 think that I'm idiotic about.

The Singaporean government manages to get by spending only 17% of GDP. http://www.heritage.org/index/country/singapore#limited-government

it's possible to have both a relatively free market and a functioning government

I don't know about Singapore, but I do know that in HK these numbers are extremely misleading.

For example, public transit is usually a loss making government function. However, in HK public transit makes a profit because the government gives them land around subway stations, where they build malls, and the MTR corporation makes money from those malls. This only works because the government owns all land in HK. Similarly, when the government subsidizes housing, this doesn't show up as a budget item because the government owns a lot of apartments, and it rents them out at below market. It can do that because it owns the flats, so all that shows up on the official expenditure is the cost of maintenance which is near zero.

Also, HK doesn't pay for defense. It gets a PLA garrison for free (half smiley).

Because there are so many things that are "off-book" I think using HK as an example of "small government" is *very* misleading. I don't know the details of Singapore, but I suspect that there are similar things going on.

Every country has elements of both, but it's a matter of degree, and the more free market less socialistic countries generally do better.

One problem here is that I don't think that you can come up with non-tauntological definition of "amount of free market."

What you can do is to just show people an economy and say "does this look like a free market to you?" which is what the various indices do. The trouble with that is that things get "tauntological." You start *defining* "free-market" as "economies that work" and *defining* "socialism" as "economies that don't." That's good marketing. Trouble with that is that it tells you nothing about the policies that you want to follow. Since Singapore "works" you can point to the parts of it that are "free market." Suppose Singapore turned out to be a basket case. Then you say "socialist!"

One reason I bring up Singapore is that there are some papers from the Heritage Foundation circa 1990 that claimed Singapore was doomed because it was too socialist. But since it worked I guess it's a free market.

I gather than in the US, socialism is a very bad and extreme word that even its supporters don't like attached to them. This is not the case in Britain, so apologies if what I say seems overly polemical to you.

It's the opposite in China, socialism is good, therefore you try to attach socialism to everything. For example, in China, you don't talk about privatization. That's a dirty word. You talk about "spreading ownership to the people" or "people managed enterprises". There is widespread admiration for the Hong Kong economy in China, so when I talk about Hong Kong as "central planning done right" that's how a lot of the political leadership in China sees it.

One other point which is extremely relevant for physics Ph.D.'s, is that the "free market" as most people imagine it, no longer exists in banking. Everything now is extremely regulated. One reason salaries have been trending down is that now the government has to approve bonus and compensation policy in most banks, and that puts downward pressure on compensation (although it still is very good).

This website claims that the fraction of households in Singapore that own their homes is 88.6% http://www.singstat.gov.sg/stats/keyind.html .

The website is correct but that's not what "ownership" means. Those are still government provided houses and sold at a subsidy. To buy *privately* needs a lot more money.

The official home ownership rate in Beijing is around 70%

http://www.kth.se/polopoly_fs/1.122089!/Menu/general/column-content/attachment/86.pdf

As with all statistics, this is with some caveats. It likely includes only official residents in Beijing. Also, the reason most urban Chinese own their homes is because the government in the mid-1990's, just gave title to worker apartments to the people occupying them.

One reason Chinese savings rates are high is that there are large numbers of people who don't have to pay rent.

1) The problem is that if the world blows up, then there are no incentives for "good" behavior.

This is the first or second thing you've said that I agree with. I asked my financial advisor what he thought about the "euro crisis" when it all started. He said that they didn't care about the political, social or emotional issues. The purpose of a bank is to make money, not prop up the state and "you wouldn't want it any other way, or you'd have moved to China". I thought about it for about 5 seconds, then I realized he was right.

Edit: For those that don't grok, the state in his words refers to all those unimportant things like 'the job market'.

Many people here (not you) not understanding the concept of "ownership" of state sponored items.

As you stated earlier, the statistics above will likely only include official residents, and hence would not take into account the large numbers of "migrant workers" i.e. those who originally come from rural areas but who migrate to urban areas for employment. Given the hukou system of residency classification, these people are unable to obtain title to real estate in the urban areas and are often denied many social services such as education, etc.

http://en.wikipedia.org/wiki/Hukou_system#Effect_on_rural_workers

Furthermore, I would be interested in knowing what the home or land ownership rates for those living in rural China. I ask this due to reports about land seizures in rural areas to make way for industrial development, and violent protests that result from this.

You can buy real estate anywhere you want, nothing to do with the Hukou system.

For a rural peasant in Guizhou province who wants to move to the city, what good would that do? You could never afford the real estate, and even if you could, you would still need the Hukou in order to get the services that you might be moving to the city for(education for your kids)?

This is getting off track. Beware the mods, people.

Different places on Wall Street have different cultures. The place that I work at cares a lot about political, social, emotional, and ethical issues.

Ummmm... Make money from whom?

This is pretty important because when I give my money to a bank, I sort of would like to get it back, and the easiest way for the person I'm giving it to to make money is to stuff that money in his pocket and disappear.

As far as "moving to China"... Well...

The first part is false, a migrant worker buy whatever land or real estate that they want, and if you have the money to buy real estate, you probably go through the bureaucracy to get your residency formally changed.

The second part is a big problem having to do with economic reality. If you could wave a magic wand and give rural residents access to free education, pensions, and health care, people would. The trouble is that there is this matter of paying for this, and a lot of tension between different groups. For example, the central government is trying to enforce a rule that says that migrants can get free education. The trouble is that then you have to figure out how to pay teachers, and so you end up with school hinting that they would like gifts.

Finally, there are situations in which someone do *not* want to change residency even if they wanted to. If you have rural residency, then you are legally entitled to farm land. So if you lose your job in the city, you can theoretical return and farm some land. The trouble with this is that increasing number of migrants have actually never farmed anything, so this is theoretical for a lot of people.

It's a tough problem, and I think the government is handling it as well as can be expected. The difficulty is not rights but services. Rural migrants have to pay "market rates" for health care and education whereas people with residency cards get those services from the government for "free".

This is why the government wants scientists. No economic growth = hard decisions. Economic growth from science and technology = you can provide free services to everyone.

Furthermore, I would be interested in knowing what the home or land ownership rates for those living in rural China.

In rural China, you are legally entitled to housing but the house is owned by the state. Rural residents don't have title to their homes (i.e. they can't sell the house), but they don't pay rent either.

Farmland is also collectively owned, but you have the legal right to a piece of farmland that you can farm and anything you make out of the farmland assigned to you is yours.

The problem comes in when the village government tries to sell a piece of land to make something like apartments. Personally, I think that the ownership system is *good* because if plots were individually owned then what would happen is that the village government would force an individual farmer to sell. Because the land is owned by the entire village, when the government tries to sell the land and pocket the money, then everyone gets mad. However, there is a another side to the picture. If the government doesn't profit from land sales then how does it pay for the schools? (If fact, the central government has taken over school funding so increasingly protests are over environmental issues.)

One other thing is that the farmers with hukou issues are a different set of farmers than the ones that protest over land sales. The people that migrate to the big cities are from places where it's pointless to protest over the money from land sales, because the land is worthless. Places where farmers protest over land sales are places where people aren't moving to the cities. Also, a poor farmer gets to the city, they generally live in a places provides by "apartment farmers." What happens is that you are a farmer in suburban Beijing and you have an allocation right to farm some land. At some point you realize that you can make more money by building some shacks, and you do it even though legally you are suppposed to use the land for farming.

I ask this due to reports about land seizures in rural areas to make way for industrial development, and violent protests that result from this.

Yup. It's an issue but people are dealing with it as rationally as they can. People have suggested some solutions and things are progressing, but it's a moderately hard problem, and a lot of the easy, obvious solutions have problems.

Also, none of this is likely to cause the government to be overthrown. Most of these protests are about money, and if you overthrow the government then everyone loses.

I'm more open about who I work for over private e-mail. One thing I find extremely annoying about the financial industry is that there are a lot of policies and in some cases laws that keep people from being too open. One thing about banking culture is that it's very "why do you need to know this?" After all, would you really trust your money to someone that gives your checking account number to anyone who asks?

chill_factor said:

The cultural differences are that I was talking about is not so much between hedge funds and investment banks, but rather between different groups and different people. It's a good thing to have a diversity of opinions.

Also hedge fund takes money from rich investors and invests them. The thing about rich investors is that they are allowed to invest in things that "ordinary people" aren't allowed to. However, the reason for this is that rich investors have the "license to be stupid with their money." If you have someone ordinary loses $100,000 in an investment, then this will be a bad thing, and if you have millions of people lose $100,000, they will demand that the government do something about it.

So the government has put in a lot of rules that "protect people from themselves" and banks and mutual funds that take money from ordinary people have to operate under strict rules. From the point of Ph.D. hiring "strict rules=boring math." Hedge funds can take money from rich people and do whatever they wanted with it as long as it isn't fraudulent. The catch is that if a rich millionaire loses $100,000 then we can just laugh at him.

You can think of an investment bank as a "wholesale financial shopping mall". Your typical investment offers a lot of services. If you want to sell real estate, you go to a real estate agent. If you want to sell a company, you go to a investment bank where they have people who are "company sales agents." Also, if you want to sell $10,000 in stocks you go to a retail broker or a mutual fund. However, if the retail broker or mutual fund wants to sell $1 million in stock, then they go to the investment bank.

No one is asking you for trade secrets like your position on a stock or your strategy in case Greece exits the Euro. They're asking what you do. I don't understand how client details even come into this, unless you're a wealth manager or something.

My personal opinion is that you are engaged in financial research of some kind in a think tank (private or government) and not directly involved in the business of the market. I think this because you are too much into philisophy and morality to be a let loose as a consultant on businesses and individuals who make enough money to make ethical discussions non-trivial. This is not to say they have none, but it would not be your job to fuss about it. You don't have the belief in your own invincibility that traders have. Every trader I know who is not married has little savings and sees regulation as a barrier to be circumvented. You have some gaps in your knowledge of how the markets work e.g. not knowing what the Fed does etc.

So a researcher. This is not a criticism. This is analysis. I am open to being corrected.

Well then you haven't taken legal and compliance training... One reason that people in finance are tight lipped is that by finding out what people do, you can figure out some things that not supposed to leak out. For example, if you know that financial institution X hired Y people to calculate Z, then you can probably figure out a lot about that strategy.

My personal opinion is that you are engaged in financial research of some kind in a think tank (private or government) and not directly involved in the business of the market.

Well you are wrong.

I think this because you are too much into philisophy and morality to be a let loose as a consultant on businesses and individuals who make enough money to make ethical discussions non-trivial.

Different places have different standards. I prefer to work somewhere with high moral and ethical standards. Now ethics is very non-trivial. It's sometimes very difficult to figure out what the *right* thing to do is, but that means that you should think about these things more rather than less.

You don't have the belief in your own invincibility that traders have. Every trader I know who is not married has little savings and sees regulation as a barrier to be circumvented.

And any trader that thinks themselves to be invinciable will get very quickly fired where I work. Good thing too.

You have some gaps in your knowledge of how the markets work e.g. not knowing what the Fed does etc.

One of the major functions of the Fed is to serve as the chief regulator for US-based financial holding companies under the Graham-Leach-Billey Act. This is actually an interesting trick question. Who is the major regulator for US investment banks? Most people would incorrectly guess the SEC.

So a researcher. This is not a criticism. This is analysis. I am open to being corrected.

Well consider yourself corrected.

Also, if you really wanted to know what I do, you could try asking? I may or may not tell you, but it's worth a shot.

I checked and you're right, the Fed does regulate. I had no idea they did. The guys I deal with are always complaining about two US regulators (US OCC and New York State's one, is it the DFS?) and the FSA (UK) being in the UK. I don't know why the Fed doesn't cover them, or perhaps it does in an way that they don't care about. The big talk right now is the New York State one because the OCC does less than nothing ([STRIKE]i.e. it's bent and you can pay it to look the other way[/STRIKE] they know people aren't in compliance, but do nothing).

No-one is asking you for trade secrets. You could say "I am working on automated trading systems" without giving anything away.

I'm really having trouble matching your experience of traders with mine. I know the US says British regulation is "lapse" but they're still bankers.

Edit: I don't for one minute believe saying you can talk about in private email and not publically makes a difference. Nothing in email is private.
