Distinguish between the short-run and long-run Phillips curves

What will be an ideal response?


The long-run Phillips curve shows the relationship between inflation and unemployment when the unemployment rate equals the natural rate and the inflation rate equals the expected inflation rate. There is no long-run tradeoff between inflation and unemployment. The short-run Phillips curve, however, shows the relationship between the inflation rate and the unemployment rate when the natural unemployment rate and the expected inflation rate do not change. The short-run Phillips curve is downward sloping, so that it shows a tradeoff between inflation and unemployment.
