1. The table above has data on the inflation rate
and the unemployment rate.
a. Using the data, label the axes and plot the
short-run Phillips curve in Figure 15.1. Label the
curve SRPC.
b. What is the effect of a decrease in the
unemployment rate from 8 percent to 5 percent?
Show the effect in Figure 15.1.
c. How does your answer to question (b) indicate
the presence of a tradeoff?
The Phillips curve is
A.
a positive relationship between price stability and constant, small-increment changes in the fiscal policy on the part of the Fed.
B.
a positive relationship in the long run between the rate of inflation and the rate of unemployment.
C.
a negative relationship between the inflation rate and the unemployment rate, at least in the short run.
D.
a positive relationship between the unemployment rate and the real Gross Domestic Product (GDP) level.

Assume that Mark gets a fixed-rate loan from a bank when the expected inflation rate is 3 percent. If the actual inflation rate turns out to be 4 percent, who benefits from the unexpected inflation: Mark, the bank, neither, or both? Explain
Question 2
What is the accelerator effect
Explain the difference between the accelerator and the multiplier.
Given that Country X has a nominal GDP of $100,000 and its real GDP is $45,000, calculate the GDP deflator.
