1.         Let’s look at Canada.  Assume an equilibrium where Aggregate Expenditure is $1,350 billion and Real GDP in $1,350 billion.  (a)  If Real GDP grew to 1,600, but AE only grew to 1,550 what is the marginal propensity to consume?  0.8

(b)  From the initial state of $1,350, what change in taxes (positive or negative and actual numeric value) would bring GDP to $1,200 billion?  

Solutions

Expert Solution

a.

MPC is the change in AE by a division of change in real GDP.

MPC = Change in AE / Change in real GDP

            = (1,550 – 1,350) / (1,600 – 1,350)

            = 200 / 250

            = 0.8 (Answer)

b.

GDP reduces from $1,350 to $1,200. Therefore, the tax effect is negative here.

GDP is the aggregate of consumption (C), private investment (I), and government spending (G).

GDP = C + I + G

If there is no change in I and G, the imposition of tax reduces consumption and this is the reason why GDP is gone down.

Amount of tax = GDP before tax – GDP after tax

                        = 1,350 – 1,200

                        = $150 (Answer)

In the expenditure–output or Keynesian cross model, the equilibrium occurs where the aggregate expenditure line (AE line) crosses the 45° line. Given algebraic equations for two lines, the point where they cross can be calculated easily. Imagine an economy with the following characteristics. Y = Real GDP or national income C = Consumption = 50 + 0.8Y I = Investment = 200 G = Government spending = 100 Calculate the equilibrium level of income (Y) Suppose G increases to 125...
