Match the statement to whether it describes rational expectations or adaptive expectations: A. Decisions are relatively slow to respond to new information about the economy B. If people expect it to rain a lot next month, they will start buying umbrellas today to take advantage of the relatively lower prices 1. Rational expectations 2. Adaptive expectations

Suppose that an economy has the Phillips curve π = π−1 − 0.5( u − 0.06). a. What is the natural rate of unemployment? b. Graph the short-run and long-run relationships between inflation and unemployment. c. How much cyclical unemployment is necessary to reduce inflation by 5 percentage points? Using Okun’s law, compute the sacrifice ratio. d. Inflation is running at 10 percent. The Fed wants to reduce it to 5 percent. Give two scenarios that will achieve that goal.

Suppose that a fall in consumer spending causes a recession. a. Illustrate the changes in the economy using both an aggregate supply/aggregate demand diagram and a Phillips curve diagram. What happens to inflation and unemployment in the short run? (5%) b. Now suppose that over time, expected inflation changes in the same direction that actual inflation changes. What happens to the position of the short-run Phillips curve? After the recession is over, does the economy face a better or worse set of inflation– unemployment combinations? (5%)

Please answer question. Thanks.

The accompanying graph depicts the Short-Run Phillips O Curve (SRPC) when the public expects no inflation in the economy. Macmillan Learning a. According to this SRPC, what would inflation be if unemployment is 9%? 0 Incorrect b. Please move the SRPC line to reflect what would happen if the public's inflation expectations increased so that they now expect the inflation rate to increase by 2%. c. If the unemployment rate is still 9%, what is the new inflation rate after this change in expectations? % 2 % Inflation rate (%) 7 6 5 4 3 2 1 0 -1 -2 -3 0 1 SRPC 2 3 4 5 6 Unemployment rate (%) 7 8 9 10
