a downward sloping line.
HW 3
1.
Which of the following is a true statement about the Phillips curve relationship? The original Phillips curve - is the negative relation between unemployment and inflation first observed in the United Kingdom.
2.
Recall that in the previous chapter the equation for wage determination took the form:
3.
Which of the following would not lead to a dec in the actual inflation rate? Dec in UR
4.
Consider the following statement:
The Phillips curve implies that when unemployment is high, inflation is low, and vice versa. Therefore, we may experience either high inflation or high unemployment, but we will never experience both together.
Is this statement true, false, or uncertain? Choose the answer that best explains.
False. If inflation expectations are high, it is possible to have high inflation and high unemployment simultaneously.
5.
The text proposes the following model of expected inflation What do we know about your process of the formation of expected inflation when = 0?
6.
Policymakers can exploit the inflation-unemployment trade-off - only temporarily, because expectations adapt to higher levels of inflation.
7.
Suppose that the Phillips curve is given by- graph 8.

2. Suppose we have an economy with
Phillips curve T^e = t + (m + z) – au. Recall
the price setting equation
P = (1+m)W = (1+m)P^eF(u,z) =
(1+m)P^e(1-au+z)
Suppose a = 1/5 , m = z = 1/20 .
a) Calculate the natural rate of
unemployment.
b) Now suppose that half of the working
population has its wages indexed - that is,
they have a constant real wage w. Derive
the new Phillips curve in this economy.
(Hint: first work out what the function F
looks like for workers with indexed wages,
then average this with the original F. You
should end up with a function that looks
like F *(u,z) = 1-a^*u+z^* - then plug the
values of a, z, m into the equation for the
Phillips curve.)

unemployment? Is it higher or lower than
before?
