NAIRU stands for Non-Accelerating Inflation Rate of Unemployment. Frictional unemployment is short-term—people between jobs, new graduates searching, relocating. Healthy economies always have some unemployment. The Phillips Curve shows a short-run trade-off: lower unemployment can raise inflation.

The natural rate of unemployment (NAIRU) is the unemployment rate at full employment—when inflation is stable. It equals frictional (job transitions) plus structural (skills mismatch) unemployment. The US NAIRU is estimated at 4.1% by the Fed. The Phillips Curve (1958) describes the inflation-unemployment trade-off. Zero unemployment is impossible in a healthy economy.

Key Takeaways
- • Natural rate = Frictional + Structural unemployment (as % of labor force).
- • NAIRU: unemployment rate where inflation is stable.
- • Cyclical unemployment = Actual rate − Natural rate (responds to demand).
- • Fed uses NAIRU to guide interest rate policy.
Did You Know?
How Does the Natural Rate Work?
Formula
Natural Rate = (Frictional + Structural Unemployed) / Labor Force × 100. Frictional: people between jobs. Structural: skills mismatch, technology, industry decline.
Phillips Curve
Short-run: lower unemployment → higher inflation. At natural rate, inflation stable. Long-run: vertical Phillips Curve at natural rate—no permanent trade-off.
Policy Implications
Unemployment above natural rate → expansionary policy may help. Below natural rate → contractionary to curb inflation. Structural unemployment needs supply-side reforms.

| Structural | Skills mismatch | Training, education |
| Cyclical | Recession, demand | Fiscal, monetary |
Frequently Asked Questions
What is the natural rate of unemployment?
The natural rate of unemployment (NAIRU) is the unemployment rate that exists when the economy is at full employment—when labor markets are in equilibrium. It includes frictional unemployment (job transitions) and structural unemployment (skills mismatch) but not cyclical unemployment. The US natural rate is estimated at 4.0–4.5% by the Fed and CBO.
What is NAIRU?
NAIRU stands for Non-Accelerating Inflation Rate of Unemployment. It is the unemployment rate at which inflation remains stable. Pushing unemployment below NAIRU tends to accelerate inflation. The Fed uses NAIRU estimates (around 4.1%) to guide monetary policy.
Frictional vs structural unemployment: what's the difference?
Frictional unemployment is short-term—people between jobs, new graduates searching, relocating. Typically 2–3% of the labor force. Structural unemployment is long-term—skills mismatch, technology displacing workers, industry decline. Typically 1–2%. Both are part of the natural rate; neither responds to demand stimulus.
Why is zero unemployment impossible?
Healthy economies always have some unemployment. Job matching takes time (frictional). Skills and jobs don't always align (structural). Attempting zero unemployment would require unsustainable wage/price controls and would likely cause runaway inflation. The natural rate represents "full employment" in economic terms.
How does the natural rate relate to inflation?
The Phillips Curve shows a short-run trade-off: lower unemployment can raise inflation. At the natural rate, inflation is stable. Below natural rate → upward pressure on wages and prices. Above natural rate → downward pressure. Long-run Phillips Curve is vertical at the natural rate.
What is the current US natural rate?
The Federal Reserve and CBO estimate the US natural rate (NAIRU) at approximately 4.0–4.5% as of 2024. It has declined from 5–6% in the 1980s due to demographics, labor market flexibility, and other structural factors. Estimates are uncertain and revised periodically.
