Document Summary

Econ 1bb3 ad-as model: draw a diagram showing a closed economy that is currently in an expansion. Show what happens to the economy in the short run. Show what happens in the short run and the long run, including the impact on output, the unemployment rate, and the price level. Describe how the economy moves from short run equilibrium to long run equilibrium (assuming that the government takes no action). Y: a closed economy begins in long run equilibrium. Increasing uncertainty about the future causes consumer spending to decline drastically. Show what happens in the short run, including the impact on output, the unemployment rate, and the price level. Now suppose that the government intervenes, using monetary policy. Show the new equilibrium, after the policy has taken effect. Y: suppose a closed economy starts in long run equilibrium. An increase in oil prices causes a negative supply shock (to the sras curve only): show the new short run equilibrium.

Due to a bust of stock prices, consumer wealth declines, and consumer confidence drops dramatically. Use the AD-AS model to predict what happens to the economy.

1. What happens to aggregate demand?

2. What happens to the level of output and the price level, both in the short-run and the long run?

3. What happens to unemployment in the short run according to Okun's law?

4. What Fed policies can be used to stabilize the economy?

Suppose the economy is in a long-run equilibrium:

a. Draw a diagram to illustrate the state of the economy.

b. Now suppose a stock market crash causes aggregate demand to fall. Use your diagram to show what happens to the price level and the output in the short run. What happens to the unemployment rate?

c. Use the sticky wage theory of aggregate supply to explain what will happen to the price level and the output in the long run(assuming there is no change in policy). What role does the expected price level play in this adjustment? Be sure to illustrate your analysis in a graph.

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*
