“The more people at work, the higher their bills” The Phillips Curve shows the correlation between unemployment and inflation.” In the light of this statement,(a) Draw the short-run trade-off between inflation and unemployment. How might the Central Bank move the economy from one point on this curve to another? (b) Draw the long-run trade-off between inflation and unemployment. Explain how the short-run and long-run trade-offs are related.
(c) Illustrate the effects of the following developments on both the short-run and long-run Phillips curves. Give the economic reasoning underlying your answers.1. A rise in the natural rate of unemployment.2. A decline in the price of imported oil.
What occurs when the natural unemployment rate increases?
A.
The short-run Phillips curve doesn't change and the long-run Phillips curve shifts rightward.
B.
The long-run Phillips curve doesn't change and the short-run Phillips curve shifts upward.
C.
The long-run and short-run Phillips curves shift rightward and the expected inflation rate rises.
D.
The long-run and short-run Phillips curves shift rightward and the expected inflation rate doesn't change.

- Using the inflation-unemployment version of the Phillips curve with adaptive expectations, ifaggregate demand increasesA)workers will realize that inflation has changed in the long run but not in the short run.B)the SRPC will immediately shift to the right as workers expect higher pricesC)workers will mistakenly work less, resulting in a decrease in inflation and increase inunemploymentD)actual inflation will be less than expected inflation, resulting in workers mistakenly workingmore and unemployment falling.arrow_forwardA. What assumptions did Thomas Sargent make when he claimed that inflation is always and everywhere a fiscal phenomenon?" B. Why is it appropriate in the book's short-term model for the author to use the Phillips Curve as an Aggregate Supply curve?

Provide an example of the book's short-run model being based on "microfoundations."arrow_forwardThe diagram opposite shows two short-run Phillips curves (PC0 and PC1). PC0 corresponds to a situation in which workers expect no inflation. Explain why this new position for the economy is untenable in the long run.
