The Phillips Curve shows the inverse relationship between unemployment and inflation. The Non-Accelerating Inflation Rate of Unemployment is the unemployment level where inflation remains stable. The short-run Phillips Curve remains useful for policy analysis, but the long-run relationship has weakened since the 1970s stagflation. The slope (ฮฒ) measures how much inflation changes per 1% change in unemployment.

The Phillips Curve, first described by A.W. Phillips in 1958, remains one of the most influential concepts in macroeconomics. It illustrates the short-run tradeoff between unemployment and inflation that central banks must navigate. The Federal Reserve explicitly considers this relationship when setting monetary policy, targeting 2% inflation while pursuing maximum employment.

- โข Fed uses this tradeoff for interest rate decisions
Did You Know?
How Does the Phillips Curve Work?
Formula
ฯ = ฯe โ ฮฒ(u โ u*) + supply shock. When u > u*, inflation falls below expected; when u < u*, inflation rises.
NAIRU
At u = u*, inflation equals expected inflation (plus any supply shock). This is the "natural" rate where inflation is stable.
Supply Shocks
Oil crises, pandemics, or supply chain disruptions shift the curve. Positive shock raises inflation at any unemployment level.
Expert Tips
Economic Regime Comparison
| Regime | u vs u* | Inflation |
|---|---|---|
| Below NAIRU | u < u* | Rising |
| At NAIRU | u = u* | Stable |
| Above NAIRU | u > u* | Falling |
Frequently Asked Questions
What is the Phillips Curve?
The Phillips Curve shows the inverse relationship between unemployment and inflation. When unemployment falls, inflation tends to rise, and vice versa. Named after economist A.W. Phillips (1958).
What is NAIRU?
The Non-Accelerating Inflation Rate of Unemployment is the unemployment level where inflation remains stable. Currently estimated at 4-5% for the US. Below NAIRU, inflation accelerates.
Is the Phillips Curve still relevant?
The short-run Phillips Curve remains useful for policy analysis, but the long-run relationship has weakened since the 1970s stagflation. Modern versions include expectations and supply shocks.
What is the slope coefficient?
The slope (ฮฒ) measures how much inflation changes per 1% change in unemployment. Historically 0.3-0.7 for the US. A steeper slope means inflation is more sensitive to unemployment changes.
What are supply shocks?
External events (oil crises, pandemics) that shift the Phillips Curve. Positive supply shocks reduce inflation at any unemployment level; negative shocks increase it (stagflation).
How does the Fed use the Phillips Curve?
The Fed monitors the unemployment-inflation tradeoff to set interest rates. When unemployment falls below NAIRU, they may raise rates preemptively to prevent inflation from accelerating.
