Question 1

Beginning at long-run equilibrium in the dynamic model of aggregate demand and aggregate supply, in the periods after a multiperiod positive demand shock occurs, the DAS shifts upward because:

Accepted Answer

Expectations of inflation increase as a result of higher inflation in previous periods, leading to a shift upward in the DAS. As individuals and firms expect higher inflation, they will demand higher wages and prices, shifting the DAS upward to achieve a higher equilibrium price level. Choices A, B, and C do not accurately describe the mechanism behind the upward shift in the DAS.

Question 7

Starting from long-run equilibrium in the dynamic model of aggregate demand and aggregate supply, a permanent reduction in the central bank's inflation target causes the nominal interest rate to:

Accepted Answer

A permanent reduction in the central bank's inflation target would initially lead to higher real interest rates as the nominal interest rate does not adjust immediately. This would reduce aggregate demand, leading to lower output and inflation. Over time, as expectations adjust to the new lower inflation target, the nominal interest rate would decline, settling at a lower level in the long run. This process describes an initial increase followed by a decline in nominal interest rates.

Question 9

A central bank that chooses a large value of θ_π and a small value of θ_Y is choosing to obtain less _____ at the expense of more _____.

Accepted Answer

A large value of θ_π indicates a strong response to inflation, reducing inflation variability, while a small value of θ_Y indicates a weaker response to output, leading to more output variability.

Question 10

Use the model of dynamic aggregate demand and aggregate supply to graphically illustrate the impact of a permanent increase in the central bank's inflation target when the economy is initially at long-run equilibrium. Explain the time path of output and inflation in words.

Question 11

Starting from long-run equilibrium in the dynamic model of aggregate demand and aggregate supply, a five-period positive demand shock causes output to _____ until returning to the natural level in the long run.

Accepted Answer

A positive demand shock causes an increase in aggregate demand in the short run. This leads to an increase in output and prices. However, in the long run, as prices adjust to the new level of demand, the economy returns to the natural level of output. This process takes time, usually several periods. Therefore, in the short run, output will move above the natural level, but in the long run, it will return to the natural level. Option B is the best choice as it reflects the short-run rise in output followed by a return to the long-run natural level.

Question 12

According to the Taylor principle, for inflation to be stable, the central bank must respond to an increase in inflation with _____ increase in the nominal interest rate.

Accepted Answer

The Taylor principle states that for inflation to be stable, the central bank must respond to an increase in inflation with a greater increase in the nominal interest rate. This is because a greater increase in interest rates helps to slow down economic activity and reduce demand, ultimately helping to reduce inflation.

Question 13

Beginning at long-run equilibrium in the dynamic model of aggregate demand and aggregate supply, if the central bank permanently reduces its inflation target, then in the initial period after the policy change, output _____, and inflation _____.

Accepted Answer

In the initial period after the central bank reduces its inflation target, the aggregate demand curve shifts leftward, leading to a decrease in output and inflation as the economy adjusts to the new lower inflation target.

Question 14

In the dynamic model of aggregate demand and aggregate supply, if the central bank chooses a large value of θ_π and a small value of θ_Y, then the DAD curve will be relatively _____, and supply shocks will have relatively _____ impacts on inflation than output.

Accepted Answer

The DAD curve will be relatively flat because a large value of θ_π means that the central bank is more concerned with inflation than output, so it will raise interest rates more aggressively in response to inflation. A small value of θ_Y means that the central bank is less concerned with output, so it will be less likely to lower interest rates in response to a negative supply shock. As a result, supply shocks will have relatively smaller impacts on inflation than output.

Question 15

Use the model of dynamic aggregate demand and aggregate supply to graphically illustrate the impact of a temporary four-period increase in taxes (a four-period negative demand shock) on output and inflation when the economy is initially at long-run equilibrium. Explain the time path of output and inflation in words.

Accepted Answer

The answer of Use the model of dynamic aggregate demand...

Question 16

Beginning at long-run equilibrium in the dynamic model of aggregate demand and aggregate supply, in the first period of a multi-period positive demand shock, output _____, and inflation _____.

Accepted Answer

In the first period of a positive demand shock, aggregate demand increases, leading to higher output and higher inflation as the economy moves away from its long-run equilibrium.

Question 17

Beginning at long-run equilibrium in the dynamic model of aggregate demand and aggregate supply, in the periods after a permanent reduction in the central bank's inflation target, the DAS shifts downward because:

Accepted Answer

Expectations of inflation decrease as a result of lower inflation in previous periods, leading to a downward shift in the Dynamic Aggregate Supply (DAS) curve. This is because the central bank's actions to reduce the inflation target influence people's expectations about future inflation, which in turn affects wage-setting and price-setting behavior, aligning with lower inflation expectations.

Question 18

Starting from long-run equilibrium in the dynamic model of aggregate demand and aggregate supply, a temporary five-period tax increase causes output to _____ returning to the natural level in the long run.

Accepted Answer

A temporary tax increase reduces disposable income, leading to a decrease in consumption and aggregate demand. This causes output to initially fall below the natural level. As the tax increase is temporary, expectations adjust, and output eventually returns to the natural level, moving above it before settling back.

Question 19

Use the model of dynamic aggregate demand and aggregate supply to compare the time paths of output and inflation in response to a one-period positive demand shock versus a one-period positive supply shock.
