According to the Phillips curve, there is an inverse relationship between unemployment and inflation. When inflation falls, there will be a temporary increase in unemployment. Therefore, the unemployment rate will temporarily rise from 7.5 percent to 9.5 percent. The Phillips curve does not suggest a permanent change in the natural rate of unemployment.
