What is the "Phillips Curve"? Why do inflation and unemployment tend to be inversely related?
An economy has the following equation for the Phillips Curve:
π = Eπ − 0.5(u − 6)People form expectations of inflation by taking a weighted average of the previous two years of inflation:
Okun’s law for this economy is:
Eπ = 0.7π−1 + 0.3π−2
(Y −Y−1)/(Y-1)=3.0−2.0(u−u−1)
Th economy begins at its natural rate of unemployment with a stable inflation rate of 5 percent.
1. What is the natural rate of unemployment for this economy?
2. Graph the short-run tradeoff between inflation and unemployment that this economy faces. Label the point where the economy begins as A.
3. A fall in aggregate demand leads to a recession, causing the unemployment rate to rise 4 percentage points above its natural rate. On your graph, label the point the economy experiences that year as point B.
The Phillips curve represents the relationship between unemployment and inflation. You are required to think about the impact on the economy of movements along the curve. If the unemployment rate in the economy is steady at 4 percent per year, how does the short-run Phillips curve predict that the inflation rate will be changing, if at all? What will happen if the unemployment rate now rises to 7 percent per year? Assume there are no changes to inflation expectations. Provide an appropriate graph to support your discussion.

- What is the Phillips Curve, and how does it relate to the trade-off between inflation and unemployment?arrow_forward1. Aggregate demand, aggregate supply, and the Phillips curve In the year 2027, aggregate demand and aggregate supply in the imaginary country of Aso-Kuju are represented by the curves AD2027 and AS on the following graph. The price level is currently 102. The graph also shows two potential outcomes for 2028. The first possible aggregate demand curve is given by the curve labeled ADA curve, resulting in the outcome given by point A. The second possible aggregate demand curve is given by the curve labeled ADB, resulting in the outcome given by point B.
