Lecture 13 chapter 10 continued (fiscal policy: a question to solve, c=100+0. 8yd, t (taxes) = 50 (lump sum: fixed amount of taxes, g = 20, x-m = 100, ynr (potential output) = 1500. Knowing that ae is equal to actual gdp (y), we can calculate ae (step 2 below): ae = c+i+g+x-m. Ae = 210+0. 8y: solve for y" : 1y-0. 8y = 210. So, this means that the change in y (actual output) is five times the change in spending. The recessionary gap is 450, so we need the y to increase by 450 given that the spending multiplier is equal to 5. C(consumption), decrease in y (output: increase in corporate taxes, decrease in profits of investments, decrease. Investment, decrease y: the relation is direct, but negative relation between taxes and output. This makes the tax multiplier to have a negative sign: to increase output, government has to reduce taxes.

Assume that the equations below describe the expenditures within a particular macroeconomy and that these equations conform to the assumptions we've made in the lecture regarding the fixed price level Aggregate Expenditure model. All values for expenditure and income are dollar amounts, but for simplicity, we've dropped the $ below.

C = 0.8(DI) + 1000	C = Consumption expenditure, DI = Disposable Income
I = 2000	I = Investment expenditure
G = 1000	G = government expenditure
X = 1600	X = spending on exports
M = 1800	M = spending on imports
DI = Y - T	Y = real GDP, T = tax revenues/>
T = 1000
Yp = 12000	Yp = Potential GDP

Given the equations above, we can describe the GDP, government budget, and net exports in this economy. Select three characteristics from the list below which accurately describe this economy. Note that there is no partial credit on this question. I.e., your answer will either be all correct, or all wrong.

	a.	inflationary gap
	b.	recessionary gap
	c.	no output gap
	d.	government budget surplus
	e.	government budget deficit
	f.	balanced government budget
	g.	trade deficit
	h.	trade surplus
	i.	net exports of zero

Suppose that the economy of Freedonia obeys the following relationships:

C = 100 + 0.6(Y ï¿½ T)

I^P = 150

G = 250

NX = 120

T = 200

a. Find the numerical equation relating to planned aggregate expenditure (PAE) to output (Y).

b. Calculate short-run equilibrium output, showing all calculations. What is the government budget balance? Does Freedoniaï¿½s government have a budget surplus or a budget deficit?

c. What is the effect of an increase in government purchases from G = 250 to G = 300 on GDP (Y)? Solve for the new level of equilibrium output. What is the multiplier? Show your work.

d. Suppose that the government simultaneously increases net taxes by 50 (that is, continue to assume that government purchases have increased by 50, as in part (c)). Calculate the new level of equilibrium output, showing your work. What is the new government budget balance? How has it changed from (b)? Does Freedoniaï¿½s government have a budget surplus or a budget deficit?

e. Assume that the equilibrium output found in (b) above is the potential output (Y*) of this economy. After the rise in both government purchases (in (c)) and net taxes (in (d)), what is the output gap in percentage terms? Is this an expansionary gap or a recessionary gap? If the natural rate of unemployment is 6%, use Okunï¿½s law to calculate what the actual unemployment rate must be.

In the AD-AS model, stagflation does not persist, because the working of the self-correcting mechanism of the economy _____ the level of output and _____ the price level until the economy eventually returns to a long-run equilibrium state, where actual output _____ potential output.

	decreases; decreases; falls short of
	increases; decreases; equals
	decreases; increases; exceeds
	decreases; increases; equals
	increases; decreases; exceeds

The LRAS curve is drawn as a vertical line at potential output (Y*) to indicate that

	Y* is independent of the price level and that actual output Y > Y* in the long run
	Y* equals actual output (Y) in the long run
	Y* is independent of the price level and that actual output Y = Y* in the long run
	Y* is independent of the price level
	Y* is independent of the price level and that actual output Y < Y* in the long run

Stagflation arises in the context of the AD-AS model when some external factor causes

	the LRAS curve to shift to the right
	the AD curve to shift leftwards
	the SRAS curve to shift downwards
	the SRAS curve to shift upwards
	the AD curve to shift rightwards

If the SRAS curve is positively sloped, then a decrease in the demand for Canadian-made goods in Europe will lead to _____ in the price level, in the short run.

	either an increase or a decrease
	no change
	an increase
	a decrease
	an initial increase, and then a decrease

Which of the following will shift the aggregate demand curve to the right?

	Consumers become pessimistic about the future
	A new technology is developed that will increase profits
	Income taxes are raised
	Foreign economies fall into recession, reducing their demand for domestic exports
	The government reduces purchases to balance the budget

Suppose a stock market crash decreases the stock of household wealth and therefore causes autonomous consumption to fall. Which of the following is the likely result?

	A leftward shift the AD curve
	There will be no movement of the AD curve
	A movement down the AD curve
	A movement up the AD curve
	A rightward of the shift the AD curve

An economy is characterized by the AD equation P = 200 ? 0.02Y, SRAS equation P = 100 and LRAS equation Y* = 5000. In the absence of any change in policy or exogenous shocks, this economy will achieve a long-run price level of

	100
	110
	120
	90
	105

The AD-AS model depicts a self-correcting economy. This means that the price level in the model adjusts automatically in response to a(n) _____ gap, so as to eliminate the _____ gap in the long run, without requiring any help from government policies.

	recessionary; recessionary
	recessionary; expansionary
	expansionary; expansionary
	output; output
	expansionary; recessionary

The aggregate demand curve shows

	the amount of planned aggregate expenditure (and output) at the current price level
	the amount of planned aggregate expenditure (and output) at an average price level
	the amount of planned aggregate expenditure (and output) at a constant price level
	the amount of planned aggregate expenditure (and output) at various price levels
	the amount of planned aggregate expenditure (and output) at last year's price level

Consider an economy initially at long-run equilibrium with output (Y) equal to potential output (Y*). If the SRAS is positively sloped, then a shift to the right of the AD curve will lead to _____ in the price level, in the short run. In the long run, the SRAS curve will shift to the _____ and the equilibrium will be at __________.

	an increase; left; Y = Y*
	a decrease; right; Y > Y*
	an increase; right; Y = Y*
	a decrease; left; Y > Y*
	no change; left; Y = Y*
