Assume that an economy is initially at the natural rate of unemployment. a. Use a Phillips curve diagram to illustrate graphically how the inflation rate and unemployment rate change both in the short run and in the long run to an unexpected expansionary monetary policy. b. Use a Phillips curve diagram to illustrate graphically how the inflation rate and unemployment rate change both in the short run and in the long run to the announcement of a credible plan of expansionary monetary policy when people have rational expectations.

Question 4Suppose a country’s inflation level is higher than desired, and unemployment levels arelower than expected – the central bank decides that the economy is ‘overheated’ andattempts to use the appropriate monetary policy to deal with the situation. Describe,with the help of the appropriate figure, how a central bank might go about implementingsuch monetary policy, the subsequent effects this has on interest rates, the quantity ofmoney in the market, and the process through which this affects the level of expenditurein the economy.

If policymakers use contractionary monetary policy to reduce inflation in the short run: O they must be willing to accept a higher rate of unemployment. O the unemployment rate will be below the natural rate of unemployment. the unemployment rate will be above the natural rate of unemployment. O the unemployment rate will be at the natural rate of unemployment.

As monetary policymakers become more concernedwith inflation stabilization, the slope of the aggregatedemand curve becomes flatter. How does the resulting change in the slope of the aggregate demand curvehelp stabilize inflation when the economy is hit with atemporary negative supply shock? How does this affectoutput? Use a graph of aggregate demand and supply todemonstrate.
