Suppose the economy is thought to be 2 percent above potential (i.e., the output gap is 2
percent), when potential output grows 4 percent per year. Suppose the Fed is following
the Taylor rule, with an inflation rate of 2 percent
over the past year. The federal funds rate is currently 3 percent. The equilibrium real fed
funds rate is 3 percent and the weights on the output gap and inflation gap are 5 each.
The inflation target is 1 percent.
a. Is the fed funds rate currently too high or too low ? By how much ? Show your work.
Suppose a year has gone by, output is now just 1 percent above potential, and inflation
rate
b. was 5 percent over the year. What federal funds rate should the Fed now set
(assuming the inflation target does not change)?
Answer:
A bank offers credit cards with a 24 percent interest rate, when its competitors’ cards
have just a 18 percent interest rate. What do you predict will happen? Will the bank
profit from its offer?
