Phillips Curve – Definition & Examples

Definition: A graphical representation of the inverse relationship between unemployment and inflation in the short run.

Detailed Explanation

The Phillips curve suggests policymakers face a tradeoff: lower unemployment comes with higher inflation, and vice versa. However, this relationship is unstable—it shifts with expectations. The long-run Phillips curve is vertical at the natural rate of unemployment, meaning no permanent tradeoff exists. Expectations-adjusted versions are more accurate.

Real-World Example

In the 1960s, the US seemed to face a stable tradeoff—lower unemployment meant accepting more inflation. The 1970s stagflation showed this wasn't permanent.

AP Economics Relevance

The Phillips curve is heavily tested on AP Macro. You'll understand short-run tradeoffs, long-run neutrality, and how expectations shift the curve.

How to Remember It

A graphical representation of the inverse relationship between unemployment and inflation in the short run. A useful definition should do more than name the concept. Try to describe Phillips Curve – Definition & Examples in your own words, give one real-world example, and name one situation where confusing it with a related term would lead to the wrong answer. That habit is especially helpful for AP, IB, and introductory college economics.
