"The appreciation of the dollar from 2012 to 2017 had a negative effect on aggregate demand in the United States." Is this statement true, false, or uncertain? (a) It is uncertain whether the appreciation of the dollar from 2012 to 2017 had a negative effect on aggregate demand because the appreciation of the U.S. dollar also affects the short-run aggregate supply curve and increases aggregate demand (b) the statement is false. An appreciation of the U.S. dollar increases net exports and according to aggregate demand and supply analysis, the aggregate demand curve shifts upward and to the right, thus increasing output. (c) The statement is true. an appreciation of the U.S. dollar decreases net exports and according to the aggregate demand and supply analysis, the aggregate demand curve shifts downward and to the left, thus reducing output.

(c) The statement is true. an appreciation of the U.S. dollar decreases net exports and according to the aggregate demand and supply analysis, the aggregate demand curve shifts downward and to the left, thus reducing output.

In many countries around the​ world, the population is aging and large segments of the population are retiring or close to retirement. What effect would this have on a​ country's long-run aggregate supply​ curve? What will happen to aggregate output as a​ result? A. The​ long-run aggregate supply curve of these countries is likely to shift to the right because of the reduction in the productive capacity of these countries. Aggregate output will decline as a resut. B. The​ long-run aggregate supply curve of these countries is likely to shift to the right because of an increase in the productive capacity of these countries. Aggregate output will increase as a resut. C. The​ long-run aggregate supply curve of these countries is likely to shift to the left because of the reduction in the productive capacity of these countries. Aggregate output will decline as a resut.

. The​ long-run aggregate supply curve of these countries is likely to shift to the left because of the reduction in the productive capacity of these countries. Aggregate output will decline as a resut. If the labor supply is reduced as a result of large portions of the population​ retiring, this reduces the productive capacity of the​ economy, resulting in a leftward shift of the​ long-run aggregate supply curve. All else​ equal, this will result in a decline in income in the country. Next Question

If huge budget deficits cause the public to think that there will be higher inflation in the future but have no effect on business or consumer​ optimism, what will happen to the position of the aggregate demand​ curve? A. Aggregate demand will not change. B. Aggregate demand will shift leftward. C. Aggregate demand will shift rightward. D.

B. wage increases are equal to productivity​ growth, and the aggregate demand curve will shift left. C. wage increases are higher than productivity​ growth, and the aggregate supply curve will shift down.

"If prices and wages are perfectly​ flexible, then γ ​= 0 and changes in aggregate demand have a smaller effect on​ output." Is this statement​ true, false, or​ uncertain? Explain your answer. A. True. When γ ​= 0, the​ short-run aggregate supply curve becomes​ steeper, and thus the effects of changes in aggregate demand on output are smaller. B. False. As prices and wages become more​ flexible, γ becomes​ larger, and thus for a given aggregate demand​ shock, the effects on output are smaller. C. False. When prices and wages are perfectly​ flexible, γ becomes​ smaller, and thus for a given aggregate demand​ shock, the effects on output are always larger. D. Uncertain. The effect on output caused by changes in aggregate demand also depends on the size of the output gap.

B. False. As prices and wages become more​ flexible, γ becomes​ larger, and thus for a given aggregate demand​ shock, the effects on output are smaller.

If stagflation is bad​ (high inflation and high​ unemployment), does this necessarily mean that very low inflation and very low unemployment is​ good? ​(Select all that​ apply.) A. Yes. Low unemployment and low inflation are associated with rapid increase in wages and thus quality of life. B. No. Having too low of an inflation rate could mean that an adverse shock could result in a deflationary episode which can be particularly damaging. C. Yes. Extremely low levels of unemployment and inflation ensures that the economy is producing at potential output levels and that the economy is growing at a modest pace. D. No. If unemployment is too low relative to the natural rate of​ unemployment, future inflation risk could build even if the current inflation rate remains relatively low.

B. No. Having too low of an inflation rate could mean that an adverse shock could result in a deflationary episode which can be particularly damaging. D. No. If unemployment is too low relative to the natural rate of​ unemployment, future inflation risk could build even if the current inflation rate remains relatively low.

As the labor force becomes more productive over​ time, how does that affect the​ long-run aggregate supply​ curve? A. The LRAS curve does not change because​ long-run aggregate supply is determined only by the total amount of capital and labor supplied in the economy. B. The LRAS curve shifts to the right because the existing labor​ force, along with a given amount of capital and other​ resources, can produce more output. C. The LRAS curve shifts to the left because there is a decrease in structural unemployment and thus a decline in the natural rate of unemployment. D. The LRAS curve becomes steeper because a persistent output gap may occur.

B. The LRAS curve shifts to the right because the existing labor​ force, along with a given amount of capital and other​ resources, can produce more output.

Why are central banks so concerned about inflation​ expectations? A. Rising concerns about inflation may shift the aggregate demand​ curve, making inflation forecasts more unpredictable. B. When inflation expectations​ rise, the​ short-run aggregate supply curve shifts​ up, leading to higher actual inflation in the short run. C. Rising concerns about inflation may cause a number of price shocks to​ occur, making it harder for the central bank to stabilize inflation. D. When inflation expectations​ rise, the​ long-run aggregate supply curve shifts​ up, decreasing the natural level of unemployment.

B. When inflation expectations​ rise, the​ short-run aggregate supply curve shifts​ up, leading to higher actual inflation in the short run.

Which of the following describes a reason why the​ long-run Phillips curve relationship differs from the​ short-run relationship?

In the long​ run, expected inflation is taken into account when making work and hiring decisions.

Does the factor affect AD? Foreign economies crash​, producing a substantial drop in net exports.

L

Does the factor affect AD? Actual output falls below potential​ output, eliminating ​"tightness" in resource markets.

No

Does the factor affect AD? The prospect of worsening inflation induces the Federal Reserve to tighten monetary policy.

The Volcker disinflation was successful in bringing inflation down with contractionary policies; however, these policies resulted in two recessions and a significant increase in unemployment

According to the​ expectations-augmented Phillips​ curve, which of the following factors determines the rate of​ inflation? A. The difference between the unemployment rate and the natural rate of unemployment. B. Expected inflation. C. The degree of tightness in the labor market. D. All of the above are correct.

if unemployment is above natural rate of unemployment, what will happen to inflation and output?

When the unemployment rate is above the natural rate of unemployment, there is slack in the labor market and output is below potential.

Yes, Right

Does the factor affect AD? War breaks​ out, forcing the government to substantially enhance defense expenditures.

Yes, left

Does the factor affect AD? Optimism within the business community induces a surge in planned business expenditures.

Yes, right

falls

Stagflation

high inflation and high unemployment

Suppose that the White House decides to sharply increase military spending without decreasing government spending in other areas. This measure​ would, all else​ constant, cause aggregate demand to:

increase

The​ self-correcting mechanism works its​ "magic" primarily through the linkage running from the
