On a given short-run Phillips curve which of the following is held constant?
a.
the level of GDP
b.
employment
c.
the unemployment rate
d.
expected inflation
Assume that the economy of Country X has an actual unemployment rate of 7%, a natural rate of unemployment of 5%, and an inflation rate of 3%.
a. Using the numerical values given above, draw a correctly labeled graph of the short-run and long-run Phillips curves. Label the current short-run equilibrium as point B. Plot the numerical values
above on the graph.
b. Assume that the government of Country X takes no policy action to reduce unemployment. In the long run, will each of the following shift to the right, shift to the left, or remain the same?
i. Short-run aggregate supply curve. Explain.
ii. Long-run Phillips curve
c. Identify a fiscal policy action that could be used to reduce the unemployment rate in the short run.
d. Draw a correctly labeled graph of aggregate demand and short-run aggregate supply, and show the impact on the equilibrium price level and real gross domestic product (GDP) of the fiscal policy
action identified in part (c).
e. Based on the change in real GDP…
To pursue economic growth in the middle of the pandemic, the government decided to increase the government’s spending.

Assume the graph represents the short-run and long-run Phillips curves before the increase in the natural rate of unemployment. 1.) Using the line drawing tool, show the effect of a higher natural rate of unemployment by drawing either a new short-run Phillips curve, a new long-run Phillips curve, or both. Label your curve(s) either 'SRPC₂' or 'LRPC2.' 2.) Using the point drawing tool, indicate the new long-run equilibrium. Label your point 'e Carefully follow the instructions above and only draw the required objects. Use your graph to explain how the increase in the natural rate of unemployment lessens the effect of high unemployment on the inflation rate. With the higher natural rate of unemployment, the inflation rate is at the long-run equilibrium.
