Assume that the equations below represent a closed economy.

Hints:

YD: Disposable Income

Y = C + I + G + NX is for part a): so, Y = 80 + MPC (YD) + I + G

C = 80 + 0.6(YD) YD = Y - T

I = 1000 T = 400

NX = (X – Im) = 0 G = 500

1. Solve for:

  • Equilibrium GDP (Y)
  • Disposable Income (YD)
  • Consumption Spending (C)
  • Private Saving
  • Public Saving
  • The multiplier

2. Verify that, in equilibrium total saving equals investment.

3. Suppose that the government wishes to increase equilibrium GDP by 100.

  • What change in government spending is required?
  • If government spending cannot change, what change in taxes is required?

Assume that GDP (Y ) is 5,000 in a closed economy. Consumption (C) is given by the equation C = 1,200+0.3(Y −T)−50r, where r is the real interest rate, in percent.

We will assume that consumption depends primarily on disposable income (i.e. C = C(Y −T)). It seems likely that in addition to disposable income, the real interest rate also influences consumption decisions. To show this, we could write the consumption function as C = C(Y −T,r), where consumption is increasing in disposable income but decreasing in the real interest rate. Answer the following questions: (a) Provide an intuitive explanation for why consumption might decrease as r increases. (b) Explain how...

Consider the closed economy Classical model depicted below, where consumption depends positively on disposable income and negatively on the real interest rate. 1) Suppose the government decides to reduce the overall level of taxes. What happens to public savings (Spublic), private savings (Sprivate), and total savings (S)?. 2) ) According to the Classical model, what are the long-run implications of the above change on the real interest rate (r), output (Y), and the expenditure components of output consumption (C), investment...
