Suppose the U.S. dollar gains strength against the euro (and against other major currencies). This strengthening of the dollar will cause which of the following to occur?

7-13 Currently, the price index used to calculate the inflation rate is equal to 90. The general expectation throughout the economy is that next year its value will be 99. The current nominal interest rate is 12 percent. What is the real interest rate?

The expected rate of inflation is equal to 100 × [(99 - 90)/90] = 10 percent. Hence the real interest rate equals the difference between the 12 percent nominal interest rate and the 10 percent anticipated inflation rate, or 2 percent

11-7 As in Problem 11-6, suppose that there is a temporary, but significant, increase in oil prices in an economy with an upward-sloping SRAS curve. In this case, however, suppose that policymakers wish to prevent equilibrium real GDP from changing in response to the oil price increase. Should they increase or decrease the quantity of money in circulation? Why?

To prevent a short-run decrease in real GDP from taking place after the temporary rise in oil prices shifts the SRAS curve leftward, policymakers should increase the quantity of money in circulation. This will shift the AD curve rightward and prevent equilibrium real GDP from declining in the short run.

11-6 Suppose that there is a temporary, but significant, increase in oil prices in an economy with an upward-sloping 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?

To prevent a short-run increase in the price level from taking place after the temporary rise in oil prices shifts the SRAS curve leftward, policymakers should decrease the quantity of money in circulation. This will shift the AD curve leftward and prevent the equilibrium price level from rising in the short run.

If equilibrium level of real Gross Domestic Product (GDP) is less than the full- employment real Gross Domestic Product (GDP) consistent with the position of the economy's long- run aggregate supply (LRAS) curve, then the difference between full- employment real Gross Domestic Product (GDP) and current equilibrium real Gross Domestic Product (GDP) is...

a recessionary gap

10-12 Explain whether each of the following events would cause a movement along or a shift in the position of the LRAS curve, other things being equal. In each case, explain the direction of the movement along the curve or shift in its position.

a. An increase in the capital stock causes real planned production to rise at any given price level, so the LRAS curve shifts rightward. b. An increase in the quantity of money causes the aggregate demand to shift rightward, which generates a movement upward along the LRAS curve. c. This reduction in the capital stock, which also will lead to higher energy prices, causes real planned production to decline at any given price level, so the LRAS curve shifts leftward. d. When the price level rises with inflation, there is a movement of the AD curve upward along the LRAS curve.

10-16 Foreachquestion,supposethattheeconomybeginsatthelong-runequilibriumpointAin the diagram below. Identify which of the other points on the diagram—points B, C, D, or E—could represent a new long-run equilibrium after the described events take place and move the economy away from point A a. Significant productivity improvements occur, and the quantity of money in circulation increases. b. No new capital investment takes place, and a fraction of the existing capital stock depreciates and becomes unusable. At the same time, the government imposes a large tax increase on the nation's households. c. More efficient techniques for producing goods and services are adopted throughout the economy at the same time that the government reduces its spending on goods and services.

a. B: Productivity improvements cause the LRAS curve to shift rightward, from LRAS1 to LRAS2, and the increase in the quantity of money in circulation causes the AD curve to shift rightward, from AD1 to AD2. b. C: The reduction in the usable portion of the capital stock reduces the economy's long-run productive capabilities, so the LRAS curve shifts leftward, from LRAS1 to LRAS3. The increase in taxes imposed on households induces them to reduce their expenditures, so the AD curve shifts leftward, from AD1 to AD3. c. E: The technological improvement shifts the LRAS curve rightward, from LRAS1 to LRAS2, and the reduction in government spending shifts the AD curve leftward, from AD1 to AD3.

11-11 For each question that follows, suppose that the economy begins at point A. Identify which of the other points on the diagram—point B, C, D, or E—could represent a new short-run equilibrium after the described events take place and move the economy away from point. a. Most workers in this nation's economy are union members, and unions have successfully negotiated large wage boosts. At the same time, economic conditions suddenly worsen abroad, reducing real GDP and disposable income in other nations of the world. b. A major hurricane has caused short-term halts in production at many firms and created major bottlenecks in the distribution of goods and services that had been produced prior to the storm. At the same time, the nation's central bank has significantly pushed up the rate of growth of the nation's money supply. c. A strengthening of the value of this nation's currency in terms of other countries' currencies affects both the SRAS curve and the AD curve.

a. E: The union wage boost causes the SRAS curve to shift leftward, from SRAS1 to SRAS3. The reduction in incomes abroad causes import spending in this nation to fall, which induces a leftward shift in the AD curve, from AD1 to AD3. b. B: The short-term reduction in production capabilities causes the SRAS curve to shift leftward, from SRAS1 to SRAS3, and the increase in money supply growth generates a rightward shift in the AD curve, from AD1 to AD2. c. C: The strengthening of the value of this nation's currency reduces the prices of imported inputs that domestic firms utilize to produce goods and services, which causes the SRAS curve to shift rightward, from SRAS1 to SRAS2. At the same time, currency strengthening raises the prices of exports and reduces the prices of imports, so net export spending declines, thereby inducing a leftward shift in the AD curve, from AD1 to AD3.

7-15 Suppose that in 2019 there is a sudden, unanticipated burst of inflation. Consider the situations faced by the following individuals. Who gains and who loses?

a. The homeowner gains; the savings bank loses. b. The tenants gain; the landlord loses. c. The auto buyer gains; the bank loses. d. The employer gains; the pensioner loses.

10-13 Explain whether each of the following events would cause a movement along or a shift in the AD curve, other things being equal. In each case, explain the direction of the movement along the curve or shift in its position.

a. When the price level falls with deflation, there is a movement downward along the AD curve. b. The decline in foreign real GDP levels reduces incomes of foreign residents, who cut back on their spending on domestic exports. Thus, the domestic AD curve shifts leftward. c. The fall in the foreign exchange value of the nation's currency makes domestic-produced goods and services less expensive to foreign residents, who increase their spending on domestic exports. Thus, the domestic AD curve shifts rightward. d. An increase in the price level causes a movement upward along the AD curve.
