Yes I am familiar with the method. The PPP calculation can get complicated but at the end its still basically GDP/PPP. The 'other factors' I referred to above especially include government subsidies. Sorry to give http://en.wikipedia.org/wiki/Purcha...es_with_PPP_comparisons_in_welfare_economics" ala Yonoz here but I am short on time:Art said:I suggest you check out the World Bank who compile these figures and read their definition and methodology. http://extsearch.worldbank.org/servlet/SiteSearchServlet?q=gdp ppp&dPgLang=ENG Many of those other factors you allude to are now included in the calculations. It may not give a perfect comparison in standards of living but it's the best indicator available and I would suggest more useful than comparing refuse collection costs.
Differing levels of government involvement in social spheres further complicate development of good CPI baskets (and, consequently, PPP measurements). For example, in 1986, nominal GDP of the United States was almost 4 times larger than the nominal GDP of the Soviet Union (on a per capita basis). Direct comparison failed to capture, however, that the Soviet Union provided free ... higher education and free healthcare to all its citizens, whereas Americans had to pay for education and healthcare themselves. To properly account for differences in quality of life in this situation, the CPI basket would have to include these expenditures explicitly. More importantly, government subsidies can potentially have large effect on consumption levels (free higher education will result in more college graduates), making it difficult to choose weights for individual components of CPI.
