Draw the modern Phillips Curve and assume v of the Phillips
Curve is 1. Show and explain the effects of the crisis. By exactly
how much should inflation change? Be sure to label everything.
When answering parts a and b, draw the
relevant Phillips curve.
Using a short-run Phillips curve, what is the effect on the
unemployment rate if the inflation rate unexpectedly rises.
Using a long-run Phillips curve, what is the effect on the
unemployment rate if the inflation rate rises and people expect the
rise.
Explain how your answer to part a about the unexpected rise in
the inflation rate changes in part b as the inflation rate becomes
expected.
ESSAY
1. Draw the Phillips curve. Use the model of
aggregate demand and aggregate supply to show how policy can move
the economy from a point on this curve with high inflation to a
point with low inflation.
2. Does inflation and unemployment would be related in the long
run? Give your explanation and draw the graph.
3. Suppose there is a tornado in western Oklahoma, causing a
supply shock for wheat. What will happen in aggregate demand and
aggergate...
3. Consider the Phillips curve: Π = EΠ - B(u - un) +
v
Π = inflation
EΠ =expected inflation
v=supply shock
u=unemployment rate
uN=natural unemployment rate
Explain the effect on the Phillips curve and the Phillips curve
tradeoff due to the Covid 19 virus.
What is the difference between the traditional Phillips curve
and the expectations augmented Phillips curve and what are the
implications of that difference for stimulatory monetary
policy?
The Phillips curve, supply shocks, and wage flexibility Suppose
that the Phillips curve is given by ?? = ?? ? − ?(?? − ?? ) (1)
where the natural rate of unemployment, ?? = ?+? ? .
[Recall that this Phillips curve was derived under price-setting
and wage-setting:
?? = (1 + ?) ?? (2)
?? = ?? ? (1 − ??? + ?) (3)
where m is the mark up over marginal cost, which is just the
wage rate...
Explain the meaning of flat Phillips curve in AD-AS framework.
Compared with the steeper Phillips curve, when the Phillips curve
is relatively flat, what is the impact of the given aggregate
demand shock on the economy?
What is the possible impact of the flat Phillips curve on fiscal
policy and monetary policy?
Assume the economy is initially in a long run equilibrium.
a. Use AD-AS and Phillips curve diagrams to show the short run
effects in prices (inflation) and output (employment) if firms are
pessimistic about economy in the future
b. In order to maintain output what would government do with
fiscal policy in response to event in part a
Suppose the economy has the Phillips curve ?? = ??−1 − 0.5(?? −
?? ? ), where the natural rate of unemployment is given by the
average of past two years’ unemployment: ?? ? = 0.5(??−1 +
??−2).
(i) Why might the natural rate of unemployment depend on recent
unemployment (as is assumed in the preceding equation)? [5]
(ii) Suppose the Central bank follows a policy to reduce the
inflation rate permanently by 1 per centage point. What effect will...
