In this video I explain the Phillips Curve and the relationship between inflation and unemploymnet. Either they alleviate unemployment and live with higher inflation, or they cause a large recession and eliminate high inflation. Indeed, some economists are discounting the supposed short-run relationship between inflation and unemployment altogether, arguing that the relationship is too volatile to be a reliable guide. The long run Phillips curve, therefore, is vertical. 1. Eventually the economy moves to point C, again a long-run equilibrium. If productivity growth is high, however, firms can pay workers higher wages and still keep price increases modest becuase those workers are more productive. Based on the previous two schools of thought we would say: nothing. 6 . A Phillips Curve can represent a theory, stating what that theory sees as a connection between inflation and unemployment.

The Phillips curve is the curve that shows the empirically fitted relationship between the rate of change of money wages (W) and the rate of unemployment (U) (see the curve PP in Figure 14.2 ignoring for the time being the vertical axis P on the right-hand side.) Economists were able to salvage the Phillips curve by realizing that a significant difference exists between the short-run and long-run relationship between inflation and unemployment.

W. Phillips argued that an inverse relationship existed between unemployment and wage inflation in the UK throughout the period in question. Points A and C each show the economy at full employment (U*), however, point C has a lower rate of inflation than point A. However, in the long run (about six years after the 1982 recession), the economy had 3 to 4 percent inflation and was back to the natural rate of unemployment. What are the Reasons for Wage Stickiness. From a Keynesian viewpoint, the Phillips curve should slope down so that higher unemployment means lower inflation, and vice versa.

On the Phillips curve plotted in the right-hand chart titled "Phillips Curve Response to an Oil Shock", the oil shock produces a movement to the northeast of point A as both unemployment and inflation increase.
