Question

The following graph depicts the short-run and long-run Phillips curves (SRPC and LRPC) for a hypothetical economy in long-run macroeconomic equilibrium at point A, where the natural unemployment rate is 6% and the current inflation rate is 8% per year.

Suppose that the central bank in this economy is concerned that inflation is too high and wants to lower the inflation rate by 6 percentage points per
year. A reduction in the rate of inflation is known as
To reduce inflation from 8% to 2% in the short run, the central bank would
have to accept an unemployment rate of
True or False: If people have rational expectations, the sacrifice ratio could be much higher than suggested by the short-run Phillips curve.

Definition Definition Relationship between the rate of unemployment and the rate of inflation that shows that the lower the initial rate of unemployment, the greater the rise in wage rate corresponding to a given rise in the rate of unemployment. The Phillips curve assumes that the ratio between prices and nominal wage rates is constant in the short run. Presented graphically, the Phillips curve shows an inverse relationship between the rate of unemployment and the rate of inflation.
