Document Summary

Macroeconomics policy chapter 24: from the short-run to the long-run: the adjustment of factor prices. Adjustment process span: the span between the short and the long run. It assumes that factor prices are flexible but that technology and factor suppliers are constant (and therefore potential national income y* is constant. Factor prices change when there is a short-run output gap. Inflationary gap leads to higher factor prices (wages) and a leftward shift in the as curve. The as curve will continue to shift leftward, raising the price level in the process, until potential income is restored. A decrease in aggregate demand opens a recessionary gap, leading to slower wage growth or possibly lower wages. If wages fall, the as curve will shift rightward, thereby generating lower prices and greater output sticky downward, takes a very long time. Adjustment symmetry: flexible wages upward, but sticky wages downward.

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.

1. In the long run, when prices are perfectly flexible:

a. aggregate supply is vertical and a market economy is self-correcting.

b. a market economy cannot self-correct.

c. government will be required to set prices to maintain equilibrium.

d. changes in aggregate demand cause equilibrium real GDP to change.

2. An increase in household wealth when the SRAS curve is upward sloping:

b. a recessionary gap

c. a decrease in the price level

d. an increase in the price level

4. The vertical long-run aggregate supply curve implies that:
