What is the effect of an increase in aggregate demand on the short-run Phillips curve?
When aggregate demand increases, _______.
A.
the short-run Phillips curve shifts upward
B.
the short-run Phillips curve shifts downward
C.
a movement occurs upward along the short-run Phillips curve
D.
a movement occurs downward along the short-run Phillips curve
The Phillips curve represents the relationship between unemployment and inflation. You are required to think about the impact on the economy of movements along the curve. If the unemployment rate in the economy is steady at 4 percent per year, how does the short-run Phillips curve predict that the inflation rate will be changing, if at all? What will happen if the unemployment rate now rises to 7 percent per year? Assume there are no changes to inflation expectations. Provide an appropriate graph to support your discussion.
The accompanying graph depicts the Short-Run Phillips
O Curve (SRPC) when the public expects no inflation in the
economy.

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?
