The Phillips curve is an economic concept developed by A. W. Phillips stating that inflation and unemployment have a stable and inverse relationship. The theory claims that with economic growth comes inflation, which in turn should lead to more jobs and less unemployment. However, the original concept has been somewhat disproven empirically due to the occurrence of stagflation in the 1970s, when there were high levels of both inflation and unemployment.
The Phillips curve states that inflation and unemployment have an inverse relationship. Higher inflation is associated with lower unemployment and vice versa.
The Phillips curve was a concept used to guide macroeconomic policy in the 20th century but was called into question by the stagflation of the 1970s.
Understanding the Phillips curve in light of consumer and worker expectations shows that the relationship between inflation and unemployment may not hold in the long run, or even potentially in the short run.
