Suppose consumption function is specified as C= $200 + 0.75Ya planned investment is $600, net taxes are $400, and
government spending totals $500 of a hypothetical economy in 2020. Find algebraically: LO 3
A. The equilibrium level of aggregate output by equating aggregate output and planned aggregate expenditure.
B. Consumption when aggregate output is at the equilibrium level.
C. Saving when aggregate output is at the equilibrium level.
D. Establish that leakages equal injections at the equilibrium level of aggregate output.

a. What is productivity in this economy?
b. What is the per-unit cost of production if the price of each input unit is $2?
c. Assume that the input price increases from $2 to $3 with no accompanying change in productivity.
What is the new per-unit cost of production? In what direction would the $1 increase in input price push
the economy's aggregate supply curve? What effect would this shift of aggregate supply have on the price
level and the level of real output?
d. Suppose that the increase in input price does not occur but, instead, that productivity increases by 100
percent. What would be the new per-unit cost of production? What effect would this change in per-unit
production cost have on the economy's aggregate supply curve? What effect would this shift of aggregate
supply have on the price…

Suppose the Japanese economy has been experiencing slow growth. As a result, the Prime Minister, who thinks John Maynard Keynes was the greatest economist ever, has decided to increase government spending. The Prime Minister asks the head of the economic council to determine the increase in government spending necessary to bring the economy to full employment. Assume there is a GDP gap of 1 trillion yen and the marginal propensity to consume (MPC) is 0.60. What advice should the head of the economic council give the Prime Minister? O The recessionary gap is equal to 400 billion yen. O The inflationary gap is equal to 400 billion yen. O The recessionary gap is equal to 625 billion yen.
