Economics - McConnell Flynn - 19 edition. Chapter 36. Textbook solutions

36.1 First, imagine that both input and output prices are fixed in the economy. What does the aggregate supply curve look like? If AD decreases in this situation, what will happen to equilibrium output and the price level? Next, imagine that input prices are fixed, but output prices are flexible. What does the aggregate supply curve look like? In this case, if AD decreases, what will happen to equilibrium output and the price level? Finally, if both input and output prices are fully flexible, what does the aggregate supply curve look like? In this case, if AD decreases, what will happen to equilibrium output and the price level? (To check your answers, review Figures 29.3, 29.4, and 29.5 in Chapter 29).

36.8 Use the equation of exchange to explain the rationale for a monetary rule. Why will such a rule run into trouble if V unexpectedly falls because of, say, a drop in investment spending by businesses?

36.9 Use an AD-AS graph to demonstrate and explain the price- level and real-output outcome of an anticipated decline in aggregate demand, as viewed by RET economists. (Assume that the economy initially is operating at its full-employment level of output.) Then demonstrate and explain on the same graph the outcome as viewed by mainstream economists.

36.10 Explain the difference between "active" discretionary fiscal policy advocated by mainstream economists and “passive” fiscal policy advocated by new classical economists. Explain: “The problem with a balanced-budget amendment is that it would, in a sense, require active fiscal policy—but in the wrong direction—as the economy slides into recession.”

36.11 Place “MON,” “RET,” or “MAIN” beside the statements that most closely reflect monetarist, rational expectations, or mainstream views, respectively:a. Anticipated changes in aggregate demand affect only the price level; they have no effect on real output.b. Downward wage inflexibility means that declines in aggregate demand can cause long-lasting recession.c. Changes in the money supply M increase PQ; at first only Q rises, because nominal wages are fixed, but once workers adapt their expectations to new realities, P rises and Q returns to its former level.d. Fiscal and monetary policies smooth out the business cycle.e. The Fed should increase the money supply at a fixed annual rate.

36.12 You have just been elected president of the United States, and the present chairperson of the Federal Reserve Board has resigned. You need to appoint a new person to this position, as well as a person to chair your Council of Economic Advisers. Using Table 36.1 and your knowledge of macroeconomics, identify the views on macro theory and policy you would want your appointees to hold. Remember, the economic health of the entire nation— and your chances for reelection—may depend on your selections.
