Diagram Description: (A diagram would be included here showing a short-run Phillips curve (SRPC) sloping upwards and a long-run Phillips curve (LRPC) vertical at the NAIRU. The point where SRPC intersects LRPC represents the NAIRU.)

The diagram illustrates the relationship between inflation and unemployment. The short-run Phillips curve shows an inverse relationship between inflation and unemployment, meaning that lower unemployment can be achieved at the cost of higher inflation, and vice versa. The long-run Phillips curve is vertical at the NAIRU, indicating that in the long run, there is no trade-off between inflation and unemployment. The NAIRU represents the level of unemployment consistent with stable inflation.

In the short run, policies aimed at reducing unemployment can be effective. For example, expansionary fiscal policy (increased government spending or tax cuts) or expansionary monetary policy (lower interest rates) can stimulate aggregate demand, leading to lower unemployment. However, this comes at the cost of higher inflation, as the economy is operating above its potential. The SRPC shifts to the right, reflecting the higher inflation rate.

In the long run, attempts to maintain unemployment below the NAIRU are unsustainable. As workers and firms anticipate higher inflation, they will demand higher wages and prices, leading to a shift in the SRPC back to its original position, intersecting the LRPC at the NAIRU. Therefore, while short-run policies can reduce unemployment, they will ultimately lead to accelerating inflation and no sustained improvement in the underlying economic situation. The long-run consequence is that the economy will return to the NAIRU, with the same level of unemployment and inflation as before the policy intervention.
