Key Concepts

Inflation Expectations

Inflation expectations play a crucial role in determining the position and slope of the Phillips curves. In the short run, if people have not fully adjusted their expectations, a temporary trade-off between lower unemployment and higher inflation might be observed. However, in the long run, adaptive expectations ensure that workers and firms adjust their behavior, resulting in a vertical long-run Phillips curve and negating any long-term impact of expansionary monetary policies on unemployment.

Monetary Policy Strategy

A monetary policy strategy aimed at achieving short-term political gains could involve implementing an expansionary monetary policy to temporarily lower unemployment. This might include lowering interest rates or increasing the money supply to shift the short-run Phillips curve downward. However, this action would likely enhance inflation expectations, and in the long run, it would result in higher inflation without reducing unemployment below its natural rate, as depicted by the vertical long-run Phillips curve.

Short-Run Phillips Curve

The short-run Phillips curve represents the inverse relationship between inflation and unemployment, indicating that in the short run, policy makers may stimulate the economy—trading a lower unemployment rate for higher inflation. However, this trade-off is temporary because inflation expectations have not yet fully adjusted to the newly anticipated higher inflation rate, allowing for this apparent benefit in reducing unemployment below its natural rate momentarily.

Long-Run Phillips Curve

The long-run Phillips curve is vertical at the natural rate of unemployment, highlighting that in the long run, there is no trade-off between inflation and unemployment. Once inflation expectations adjust, any attempt to lower unemployment below its natural level only leads to higher inflation without a sustained reduction in unemployment. This outcome illustrates the concept of monetary neutrality over the long term.
