Economics Phillips Curve Questions
The Phillips Curve is a concept in economics that shows the relationship between inflation and unemployment. It suggests that there is a trade-off between these two variables, meaning that when unemployment is low, inflation tends to be high, and vice versa.
In the context of the adaptive Phillips Curve, it is based on the idea that workers and firms form their expectations about future inflation based on past experiences. According to this theory, if inflation is higher than expected, workers will demand higher wages to compensate for the loss in purchasing power, leading to an increase in labor costs for firms. As a result, firms may increase prices to maintain their profit margins, causing inflation to rise further.
Conversely, if inflation is lower than expected, workers may accept lower wage increases, and firms may reduce prices to remain competitive, leading to a decrease in inflation. This suggests that there is a lag in the adjustment of inflation expectations, as workers and firms gradually update their expectations based on past outcomes.
Overall, the adaptive Phillips Curve highlights the importance of expectations in shaping the relationship between inflation and unemployment. It suggests that changes in inflation are influenced by the gap between actual and expected inflation, and that the speed of adjustment in expectations can impact the trade-off between inflation and unemployment in the short run.
