What shifts the long run Phillips curve?
The long-run Phillips curve is vertical at the natural rate of unemployment. Shifts of the long-run Phillips curve occur if there is a change in the natural rate of unemployment .
Why does the Phillips curve not work?
The real problem with the Phillips curve is not that it supposes that inflation and unemployment are related, especially in the short run, but that it misconstrues that relation as involving a direct causal influence of unemployment on inflation, and vice versa, when in fact it is changes in aggregate demand that cause ...
