Answer to Problem 8TY

The equilibrium level of GDP is derived as $5,192 for the rate of interest at 2 percent (r=0.02)

Explanation of Solution

Substituting the values of rate of interest 2 percent (r=0.02)

in the investment function and the total investment is being calculated as follows:

  I=1,000100r   =1,000100(r)   =1,0002   = 998

The equilibrium level of GDP is derived as follows:

  Y=(300+0.75Y)+998+0+0   =300+0.75Y+998   =1,298+0.75Y

By bringing the variable Y

to the left hand side:

    Y0.75Y=1,298Y(10.75)=1,298        0.25Y=1,298               Y=12980.25               Y= 5,192

Therefore, the equilibrium level of GDP is $5,192 at rate of interest 2 percent (r=0.02) .

Answer to Problem 8TY

The equilibrium level of GDP is derived as $5,180 for the rate of interest at 5 percent (r=0.05)

Explanation of Solution

Substituting the values of rate of interest 5 percent (r=0.05)

in the investment function and the total investment is being calculated as follows:

  I=1,000100r   =1,000100(0.05)   =1,0005   = 995

The equilibrium level of GDP is derived as follows:

  Y=(300+0.75Y)+995+0+0   =300+0.75Y+995   =1,295+0.75Y

By bringing the variable Y

to the left hand side:

    Y0.75Y=1,295Y(10.75)=1,295        0.25Y=1,295               Y=12950.25               Y= 5,180

Therefore, the equilibrium level of GDP is $5,180 at rate of interest 5 percent (r=0.05)

Answer to Problem 8TY

The equilibrium level of GDP is derived as $5,160 for the rate of interest at 10 percent (r=0.10)

Explanation of Solution

Substituting the values of rate of interest 10 percent (r=0.10)

in the investment function and the total investment is being calculated as follows:

  I=1,000100r   =1,000100(0.10)   =1,00010   = 990

The equilibrium level of GDP is derived as follows:

  Y=(300+0.75Y)+990+0+0   =300+0.75Y+990   =1,290+0.75Y

By bringing the variable Y

to the left hand side:

    Y0.75Y=1,290Y(10.75)=1,290        0.25Y=1,290               Y=12900.25               Y= 5,160

Therefore, the equilibrium level of GDP is $5,160 at rate of interest 10 percent (r=0.10)

(a) Suppose in a simple Keynesian economy, planned consumption function is given by C=250+0.65(Y-T). Planned investment, government purchases, taxes are $100 million, $100 million and $150 million respectively. What is MPC, MPS and autonomous consumption Derive the saving function. What is the equilibrium level of income? Y= AD=C+I+G If government purchases increase to $150 million, what is the new equilibrium level of income? What level of government purchases is needed to achieve an income of $2000 million? From question e) you get the newly government purchase. Now find out the multiplier value What is the amount of shift in AD curve?

Demand Supply Supply Demand LOANABLE FUNDS (Billions of dollars) Scenario 1: Individual Retirement Accounts (IRAS) allow people to shelter some of their income from taxation. Suppose the maximum annual contribution to such accounts is $5,000 per person. Now suppose there is an increase in the maximum contribution, from $5,000 to $8,000 per year. Shift the appropriate curve on the graph to reflect this change. This change in the tax treatment of saving causes the equilibrium interest rate in the market for loanable funds to and the level of investment spending to Scenario 2: An investment tax credit effectively lowers the tax bill of any firm that purchases new capital in the relevant time period. Suppose the government repeals a previously existing investment tax credit. Shift the appropriate curve on the graph to reflect this change. The repeal of the previously existing tax credit causes the interest rate to and the level of investment to Scenario 3: Initially, the government's…
