2. The Phillips curve in the short run and long run In the year 2020, aggregate demand and aggregate supply in the fictional country of Demet are represented by the curves AD2020 and AS on the following graph. Suppose the natural level of output in this economy is $6 trillion. On the following graph, use the green line (triangle symbol) to plot the long-run aggregate supply (LRAS) curve for this economy. 108 107 LRAS AS 100 Outcome C 103 102 AD 100+ 100 2 10 OUTPUT (Troof dolar) Economists have forecast that if the government does nothing and the economy continues to grow at the current rate, aggregate demand in 2021 will be given by the ADA curve, resulting in the outcome illustrated by point A. If the government pursues an expansionary policy, aggregate demand in 2021 will be given by the ADB curve, resulting in the outcome illustrated by point B. The following table gives projections for the unemployment rates that would occur at point A and point B. Consider what the rate of inflation would be between 2020 and 2021, depending on whether the economy moves from the initial price level of 102 to the price level at outcome A or the price level at outcome B. Complete the table by entering the inflation rate at each potential outcome point. Note: Calculate the inflation rate to two decimal points of precision.

line:
At the natural level of output
At the natural rate of unemployment
Representing the tradeoff between unemployment and inflation
Now consider the long-run effects of this policy. Suppose, in particular, that following
implementation of the policy, the aggregate demand curve remains at ADB. Designate the long-
run equilibrium that would follow such a policy as outcome C.
Going back to the first graph, place the grey point (star symbol) at outcome C.
Because output at point C is
associated with outcome C is
the natural level of output, the unemployment rate
the natural rate of unemployment.
Finally, use the green line (triangle symbol) to draw the long-run Phillips curve (LRPC) on the
second graph.
This line is

Economists have forecast that if the government does nothing and the economy continues to grow
at the current rate, aggregate demand in 2021 will be given by the ADA curve, resulting in the
outcome illustrated by point A. If the government pursues an expansionary policy, aggregate
demand in 2021 will be given by the ADB curve, resulting in the outcome illustrated by point B.
The following table gives projections for the unemployment rates that would occur at point A and
point B. Consider what the rate of inflation would be between 2020 and 2021, depending on
whether the economy moves from the initial price level of 102 to the price level at outcome A or
the price level at outcome B.
Complete the table by entering the inflation rate at each potential outcome point.
Note: Calculate the inflation rate to two decimal points of precision.
