Macroeconomics Chapter 18

Hire more workers to produce more

If the Fed causes aggregate demand and the price level to rise higher than expected, in the short run firms will:

Inflation

If the Fed expands AD faster than economic growth shifts AS, then the economy will experience:

Lower

If the actual inflation rate is ____________ than the expected rate, firms will find their profits shrinking, which causes them to reduce output and thus unemployment rises.

Even more inflation will occur

If the government attempts to maintain full employment when there is cost-push inflation,

Will go back to its initial equilibrium

If the government does not intervene in a cost-push inflation situation, the price level in the long run:

Waits for wages and other input costs to fall in order to get back to full-employment

If the government takes a hands-off approach to cost-push inflation, it:

The recession could linger too long

If the long-run adjustments to cost-pull inflation, as predicted by the extended AD-AS model, do not happen quickly enough,

Stay constant; rise

If the price level rises in the short run, nominal wages will____________, and firms' output will therefore ____________.

-The economy faces an unemployment problem -Total output is below potential GDP

If the unemployment rate is greater than the natural rate, which of the following statements are also true?

Stagnation; inflation

"Stagflation" is coined by the media by combining the words ____________ and ____________.

The shape of the short-run Phillips Curve reflects

-The consequences of shifting aggregated demand along an upward-sloping aggregate supply curve -A trade-off between inflation and unemployment

The sequence of events resulting from an increase in aggregate demand beginning at point a2 is

1. The price level rises and firms will try to produce more output. 2. Unemployment falls while nominal wages remain fixed in the short run. 3. Workers and firms adjust their inflation expectations and negotiate for higher wages. 3. Employment declines and unemployment rises

Employing otherwise naturally unemployed workers

A nation that operates beyond its full employment or potential output level is:

Firms and workers have not adjusted their inflation expectations to match actual inflation

A point on the short-run Phillips Curve but not on the long-run Phillips Curve is not a stable equilibrium because:

Only in the short-run

A trade-off between inflation and unemployment exists:

-Higher after-tax earnings -Greater work effort

According to supply-side economics, which of the following are consequences of reducing marginal tax rates on income?

-Work and produce -Save and invest

According to supply-side economists, rising taxes in the U.S. have adversely affected incentives to:

b) Higher after-tax income

According to supply-siders, which of the following will encourage more work effort? a) Larger benefits from leisure b) Higher after-tax income c) Higher marginal tax rates d) Lower after-tax earnings

Demand-pull inflation is the result of the

Ad curve shifting to the right.

Output and rising prices

Adverse supply shocks tend to cause falling:

Which of the following descriptions are characteristics of an economy in its long-run equilibrium?

Aggregate demand intersects both short-run and long-run aggregate supply at the same point; There is no GDP gap.

Increases

Along the short-run aggregate supply curve (SRAS), output increases when the price level ____________.

-Changes in marginal tax rates affect people's incentives to work, save, and invest -Tax cuts tend eventually to raise tax revenues

Among the important elements of supply-side economics are the following ideas:

Left; Unemployment; Increase

An adverse supply shock causes the short-run aggregate supply curve to shift to the ____________, in turn causing ____________ and the price level to ____________.

-Higher than the actual inflation rate, so firms produce less as a result of weakening aggregate demand

An economy may temporarily slide down along its short-run Phillips Curve if the expected inflation rate is:

-Short-run aggregate supply curve at the full employment level of output -Short-run and long-run aggregate supply curves at the same point

An economy's long-run equilibrium occurs when the aggregate demand (AD) curve intersects the

-Short-run and long-run aggregate supply curves at the same point -Short-run aggregate supply curve at the full employment level of output

An economy's long-run equilibrium occurs when the aggregate demand (AD) curve intersects the:

Which of the following would cause an economy to travel along a stable short-run Phillips Curve?

An increase in aggregate demand

Cost-push inflation

An increase in the costs of inputs, such as wages, leads to:

1) The short-run AS curve shifts left 2) Output falls, creating a negative GDP gap 3) Demand for labor weakens pulling nominal wages down 4) The short-run AS curve shifts to the right 5) Long-run equilibrium is attained when output is at the full employment level

As a result of a sharp increase in the price of oil and coal, the correct sequence of events would be:

Some people work more but others work less

Critics of supply-side economics point to evidence that shows decreases in wage-income tax rates make:

-Slow to emerge -Of uncertain direction -Small

Critics of the Laffer Curve and its supply-side implications say ample empirical evidence shows that the impact of a tax cut on incentives is:

Inflation; long

There is no significant trade-off between unemployment and ____________ in the ____________ run.

In the short run, which of the following shifts could cause a recession?

Decrease in aggregate supply; decrease in aggregate demand

AD curve shifting to the right

Demand-pull inflation is the result of the

1) Aggregate demand increases 2) The price level increases and a positive GDP gap occurs 3) Demand for labor rises and causes nominal wages to rise 4) The short-run AS curve shifts to the left 5) Output goes back to the full employment level

Demand-pull inflation occurs in response to a chain of events occurring in the following order:

Supply; left

Higher rates of unemployment and inflation would result in the short run as a result of a shift of the aggregate ____________ curve to the ____________.

-By extending the work hours of current workers -By hiring and training the structurally employed -By enticing new workers into the labor force and hiring them

How might firms in an economy produce an output level that exceeds the potential GDP?

Output; Decline; Supply; Slowly

If aggregate demand declines, then a recession occurs, which means ____________ decreases. In the extended AD-AS model, it causes wages to ____________, which shifts the aggregate ____________ until the economy reaches full employment again. This reasoning is controversial because the changes described could happen very ____________.

Nominal wages will fall as workers and firms lower their inflation expectations

If aggregate demand decreases and takes the economy away from its long-run Phillips Curve, what mechanism will allow the economy to self-adjust back to the long-run Phillips Curve?

1) Firms will reduce their total output level 2) The unemployment rate rises above the natural rate 3) Nominal wages fall 4) The short-run aggregate supply curve shifts right 5) Real output goes back to the full employment level

If an economy is initially at full employment, and the price level falls, long-run adjustments would occur in the following order:

1) Output would increase beyond potential GDP 2) Nominal wages would increase 3) The short-run aggregate supply curve would shift left 4) Real output would go back to the full employment level

If an economy is initially at full employment, and the price level rises, long-run adjustments would occur in the following order:

Greater

If an economy is operating at an unemployment rate below its natural rate, then its output level must be ____________ than its potential GDP.

In the extended AD-AS model, if an economy at full employment experiences an increase in AD, in what order do the following events occur?

1) Demand for labor decreases 2) Wages fall 3) Aggregate supply increases 4) Real output rises

In the extended AD-AS model, the likely order of events resulting from a recession is as follows:

1) AD shifts to the right 2) Output rises above potential GDP 3) Wages increase 4) The short-run AS curve shifts left 5) The price level rises and output falls back

In the extended AD-AS model, the sequence of events in a situation of demand-pull inflation is as follows:

-Rising inflation expectations -An economy that travels up a vertical Phillips Curve -Continuing inflation -Continuing shifts of the short-run Phillips Curve up and to the right

In the long run, continued increases in aggregate demand will cause which of the following?

Only in the short run

In the extended AD-AS model, if an economy at full employment experiences an increase in AD, in what order do the following events occur?

Output rises above potential GDP; Nominal wages are driven up as demand for labor increases; The short-run aggregate supply curve shifts left, causing the price level to rise.
