Suppose the economy is operating below potential output. Inflation is 2% and expected inflation is 3%....
2. Phillips Curve. An economy has the following functions for its short run aggregate supply (SRAS), Okun's Law (OL), and Phillips Curve (PC): SRAS: P = EP + (1/2)(y - 3) OL: (Y-Y) = -4(u-u") PC:T = ET - (1/5)( - 6) The economy begins at its natural rate of output with a stable price level equal to $5. a.) Output is at its natural level when the price level is equal to expectations. Calculate the natural rate of output...
Problem 3.(36 points) Suppose the natural rate of unemployment equals 5%, and the Phillips curve is given by πt = πte − 0.25(ut − u∗t ). Suppose originally the economy is in the long run equilibrium, in which πte = 4%. 1. Determine unemployment and inflation rates corresponding to the original equilibrium. 2. Draw the Philips curve diagram with SRPC and LRPC. Mark the original long run equilibrium. 3. Suppose now the central bank performs a monetary expansion and raises...
Suppose the economy is in a long-run equilibrium, as shown on the following graph. Now suppose a wave of business pessimism reduces aggregate demand. On the following graph, shirt a curve or adjust the point to reflect the short-run effect of business pessimism. LRPC Inflation Rate SRPC Unemployment Rate If the Fed undertakes expansionary monetary policy, it return the economy to its original inflation rate and original unemployment rate. Now, suppose the economy is back in long-run equilibrium, and then...
1. Is the Phillips curve a myth? Intertemporal tradeoff between inflation and unemployment After the World War II, empirical economists noticed that, in many advanced economies, as unemployment fell, inflation tended to rise, and vice versa. The inverse relationship between unemployment and Inflation, was depicted as the Phillips curve, after William Phillips of the London School of Economics. In the 1950s and 1960s, the Phillips curve convinced many policy makers that they could use the relationship to pick acceptable levels...
If the economy is at the natural rate of unemployment with the level of real GDP at potential output, what would expansionary fiscal or monetary policy do to the economy? How would the economy be effected in the short run and long run? Does the Phillips Curve theory explain what happens?
4. Problems and Applications Q4Suppose the economy is in a long-run equilibrium, as shown on
the following graph. Now suppose a fall in government purchases
reduces aggregate demand.On the following graph, shift a curve or adjust the point to
reflect the short-run effect of reduction in government
purchases.True or False: If the Fed undertakes
expansionary monetary policy, it can return the economy to its
original inflation rate and original unemployment rate.
________ Now, suppose the economy is back in long-run equilibrium, and...
Consider the short-run and long-run Phillips Curves illustrated in the figure below. Assume consumers have a daptive expectations. Suppose the inflation rate has been 15 percent for the past four years. The unemployment rate is currently at the natural rate of unemployment of 5 percent. The Federal Reserve decides that it wants to permanently reduce the inflation rate to 5 percent and uses monetary policy to do so. Describe the new short-run Phillips Curve with adaptive expectations. PC- PC- Inflation...
4. The costs of inflation and of combating inflation The following graph shows a short-run Phillips curve for a hypothetical economy. Show the short-run effect of a contractionary monetary policy by dragging the point along the short-run Phillips curve (SRPC) or shifting the curve to the appropriate position. ? 12 11 10 SRPC 8 4 SRPC 3 2 1 0 1 4 5 UNEMPLOYMENT (Percent) INFLATION RATE Percent) Now, show the long-run effect of a contractionary monetary policy by dragging...
Which of the following statements would be true if the short-run Phillips curve relationship held in the long run? a. Only monetary policy, not fiscal policy, has any real effects on the economy. b. A central bank can always steer an economy out of recession, simply through creating inflation. c. Expansionary monetary policy can decrease inflation at the expense of unemployment. d. A central bank has no control over unemployment. e. Prices fully adjust in the long run.
3. Aggregate Supply Shocks Suppose that a small economy that depends mostly on agriculture experiences a year with exceptionally good conditions for growing crops. What would the good weather do to the Short-run Aaggregate Supply curve and the Short-run Phillips Curve? a. It would shift both the Short-run Aggregate Supply Curve and the Short-run Phillips Curve b. It would shift both the Short-run Aggregate Supply curve and the Short-run Phillips Curve c. It would shift the Short-run Aggregate Supply Curve...
