2. Why Does Whirlpool Care about Monetary Policy? Learning Objectives In 2006, Whirlpool, headquartered in Benton Harbor, Michigan, had 73,000 employees and $18 billion in annual sales. In 2001 and the following years, Whirlpool clearly benefited from the effects of monetary policy. Use a Phillips curve graph to show how the Federal Reserve can permanently lower the inflation rate . 16.4 Discuss how expectations of the inflation rate affect monetary policy. 16.3 Explain the relationship between the short-run and long-run Phillips curves . 16.2 Describe the Phillips curve and the nature of the short-run trade-off between unemployment and inflation. 16.1

5. The Discovery of the Short-Run Trade-off between Unemployment and Inflation Structural relationship A relationship that depends on the basic behavior of consumers and firms and remains unchanged over long periods. Learning Objective 16.1 Is the Phillips Curve a Policy Menu? Is the Short-Run Phillips Curve Stable? During the 1960s, the basic Phillips curve relationship seemed to hold because a stable trade-off appeared to exist between unemployment and inflation. Then in 1968, in his presidential address to the American Economic Association, Milton Friedman of the University of Chicago argued that the Phillips curve did not represent a permanent trade-off between unemployment and inflation.

The Discovery of the Short-Run Trade-off between Unemployment and Inflation Learning Objective 16.1 The Role of Expectations of Future Inflation Table 16-2 The Basis for the Short-Run Phillips Curve the unemployment rate rises. the actual real wage is greater than the expected real wage, actual inflation is less than expected inflation, the unemployment rate falls. the actual real wage is less than the expected real wage, actual inflation is greater than expected inflation, AND… THEN… IF…

17. Changing Views of the Phillips Curve Learning Objective 16.2 Writing in a Federal Reserve publication, Bennett McCallum, an economist at Carnegie Mellon University, argues that during the 1970s, the Fed was “acting under the influence of 1960s academic ideas that posited the existence of a long-run and exploitable Phillips-type tradeoff between inflation and unemployment rates.” Solved Problem 16-2

18. Expectations of the Inflation Rate and Monetary Policy • Low inflation. • Moderate but stable inflation. • High and unstable inflation. Learning Objective 16.3 Rational expectations Expectations formed by using all available information about an economic variable. The experience in the United States over the past 50 years indicates that how workers and firms adjust their expectations of inflation depends on how high the inflation rate is. There are three possibilities:

26. How the Fed Fights Inflation Learning Objective 16.4 De-emphasizing the Money Supply The Importance of Fed Credibility The Fed learned an important lesson during the1970s: Workers, firms, and investors in stock and bond markets have to view Fed announcements as credible if monetary policy is to be effective.

27. How the Fed Fights Inflation Learning Objective 16.4 Monetary Policy Credibility after Greenspan A Failure of Credibility at the Bank of Japan Debate continues over policies to increase the Fed’s credibility. Some economists and policymakers believe that central banks are more credible if they adopt and follow rules. Economists and policymakers who oppose the rules strategy support a discretion strategy for monetary policy Many economists believe a middle course between a rules strategy and a discretion strategy is desirable. Most economists believe the best way to achieve commitment to rules is to remove political pressures on the central bank.
