PV of Income Path: Y1=100, Y2=125 & r=0.5

In summary, the PV of Income Path refers to the current value of future income streams, taking into account the time value of money. It is calculated by discounting the future cash flows by a specific rate of return, also known as the discount rate. This can be calculated using the formula PV = C1/(1+r)^1 + C2/(1+r)^2 + ... + Cn/(1+r)^n, where C1-Cn represent the cash flows in each period and r is the discount rate. It is important because it allows for comparison of future income streams to their present value, and helps with financial decision making. A higher discount rate results in a lower present value, and the timing of cash flows greatly affects the

Homework Statement


What is the permanent income that corresponds to present value of the two period income path Y 1 =100, Y 2 =125 for the real interest rate r=.5? (Note: 50% not ½%!)



Homework Equations



PV = Y1 + Y2/(1+r)^t

The Attempt at a Solution




Correct Answer:

a) 110

I did Pv = 100 + 125/1,5 = 183, but the answer is 110!?

i found the anser, it s the definition

1+r/2+r x y1 + y2/1+r !

its 109,8
 

1. What is the PV of Income Path?

The PV (present value) of Income Path refers to the current value of future income streams, taking into account the time value of money. It is calculated by discounting the future cash flows by a specific rate of return, also known as the discount rate.

2. How is the PV of Income Path calculated?

The PV of Income Path is calculated by using the formula PV = C1/(1+r)^1 + C2/(1+r)^2 + ... + Cn/(1+r)^n, where C1-Cn represent the cash flows in each period and r is the discount rate. In this case, the cash flows are Y1=100 and Y2=125, and the discount rate is 0.5. Plugging these values into the formula, we get PV = 100/(1+0.5)^1 + 125/(1+0.5)^2 = $223.61.

3. Why is the PV of Income Path important?

The PV of Income Path is important because it allows us to compare the value of future income streams to their present value. This is useful for making financial decisions, such as investments or budgeting, as it takes into account the time value of money. It also helps to determine the potential profitability of an investment or project.

4. What does a higher discount rate mean for the PV of Income Path?

A higher discount rate means that the future cash flows are being discounted at a higher rate, resulting in a lower present value. This means that the value of the income stream in the future is worth less in present terms, which can be due to factors such as inflation or the risk associated with the investment.

5. How does the timing of cash flows affect the PV of Income Path?

The timing of cash flows can greatly affect the PV of Income Path. In general, the sooner the cash flows are received, the higher the PV will be. This is because the discount rate takes into account the time value of money, meaning that money received in the present is worth more than the same amount received in the future. Therefore, the longer the time frame for the cash flows, the more they will be discounted and the lower the PV will be.
