As in Problem , suppose that there is a temporary, but significant, increase in oil prices in an economy with an upward-sloping curve. In this case, however, suppose that policymakers wish to prevent equilibrium real from changing in response to the oil price increase. Should they increase or decrease the quantity of money in circulation? Why?
Consider Figure 11-10. Suppose that the real interest rate suddenly declines for reasons that do not relate to the price level. What happens to the nation's aggregate demand curve? In the short run, will the nation experience an inflationary gap or a recessionary gap? Explain.
How has the fact that thousands of people from Puerto Rico have moved to the United States to search for jobs likely influenced Puerto Rico's official unemployment rate? Explain your reasoning.
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. Briefly explain your answers.
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.
Based on your answers to Problems and , can policymakers stabilize both the price level and real simultaneously in response to a short-lived but sudden rise in oil prices? Explain briefly.
