Document Summary

Econ 102 lecture 16 aggregate supply and e ects of shivs. Sum of total produc2on of all rms in the economy. Represents the rela2onship between overall price level in the economy and total produc2on by rms. As is representa2ve as a whole, not from any one rm, so naturally its graph refers to the whole, not individual rms. There is a long run and short run as (lras, sras) This is because as describes behaviour of rms, and in the long run price has nothing to do with it. In the short run, we assume input prices are not changing, so if the rm is able to get a higher price for their output they have an incen2ve to do so. In other words, they do not have to pay workers more or pay more for more resources (input prices) Y1 and y2 and p1 and p2 stand for output and price respec2vely.

Oil Price Shocks
Both the long-run aggregate supply curve and the short-run aggregate supply curve shift in response to changes in the availability of labor or capital or to changes in technology and productivity. A widespread temporary change in the prices of factors of production, however, can cause a shift in the short-run aggregate supply curve without affecting the long-run aggregate supply curve.

Tasks:
Suppose there is a temporary but significant increase in oil prices in an economy with an upward-sloping Short-Run Aggregate Supply (SRAS) curve. If policymakers wish to prevent the equilibrium price level from changing in response to the oil price increase, should they increase or decrease the quantity of money in circulation? Why?

1) If actual (equilibrium ) real GDP is less than the full-employment, or natural, level of real GDP, then wages and other input prices are expected to:

a. fall and SRAS to shift to the left until long-run equilibrium is achieved.

b. fall and SRAS to shift to the right until long-run equilibrium is achieved.

c. rise and SRAS to shift to the left until long-run equilibrium is achieved.

d. rise and SRAS to shift to the right until long-run equilibrium is achieved.

2) In a self-regulating economy, inflationary gaps are automatically eliminated in the long run by:

a. decreases in wage rates that cause short-run aggregate supply to shift rightward.

b. decreases in wage rates that cause short-run aggregate supply to shift leftward.

c. increases in wage rates that cause short-run aggregate supply to shift rightward.

d. increases in wage rates that cause short-run aggregate supply to shift leftward.

3) Assume the economy is initially in equilibrium at the full-employment level of real GDP. If businesses and consumers become pessimistic regarding future economic conditions, ceteris paribus, the aggregate demand curve will shift to the ________, causing the level of output to ______.

a. left; fall

b. right; fall

c. left; rise

d. right; rise

4) Economists that advocate a macroeconomic policy of laissez-faire:

a. believe the economy is self-regulating only if the government intervenes to move the economy to equilibrium at natural real GDP.

b. believe the economy is self-regulating and will automatically move to equilibrium at natural real GDP in the long run.

c. also advocate central planning and government control of resources.

d. also advocate active government intervention in the economy.

5) Which of the following summarizes the process for closing a recessionary gap if the economy is self-regulating?

a. Labor shortages put upward pressure on wages, which leads to higher costs of production and a decrease in short-run aggregate supply.

b. Labor shortages put downward pressure on wages, which leads to increases in employment and spending and an increase in aggregate demand.

c. Unemployed resources put upward pressure on the price level, which leads to higher wages, increases in spending, and increases in aggregate demand.

d. Unemployed resources put downward pressure on the price level, which leads to lower costs of production and an increase in short-run aggregate supply.

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*
