Adaptive expectations play a crucial role in the Phillips Curve theory by influencing the relationship between inflation and unemployment. The Phillips Curve suggests an inverse relationship between these two variables, stating that when unemployment is low, inflation tends to be high, and vice versa.
Adaptive expectations refer to the idea that individuals form their expectations about future inflation based on past experiences. In other words, people adapt their expectations of inflation based on the recent history of inflation rates. This means that if inflation has been high in the past, individuals will expect it to remain high in the future, and if it has been low, they will expect it to stay low.
In the context of the Phillips Curve theory, adaptive expectations influence the behavior of workers and firms when negotiating wages. When workers expect high inflation, they will demand higher wage increases to compensate for the expected rise in prices. Similarly, firms will anticipate higher costs due to inflation and may increase prices to maintain their profit margins. These wage and price adjustments based on adaptive expectations can lead to an increase in inflation.
Conversely, when workers and firms expect low inflation, they may be more willing to accept smaller wage increases or even wage cuts. This can help reduce inflationary pressures in the economy.
Therefore, adaptive expectations affect the behavior of economic agents and their decisions regarding wages and prices, which in turn impact the relationship between inflation and unemployment as depicted by the Phillips Curve.
