What is the Inflation-Unemployment Tradeoff?
The inflation-unemployment tradeoff is a fundamental relationship in macroeconomics: when unemployment falls, inflation tends to rise, and vice versa. This inverse relationship, first documented by economist A.W. Phillips, shows that policymakers face a difficult choice: they can achieve lower unemployment at the cost of higher inflation, or lower inflation at the cost of higher unemployment.
The inflation-unemployment tradeoff is an inverse relationship where lower unemployment pushes inflation up, and higher unemployment pulls inflation down. Policymakers must choose between these competing goals.
Step-by-step worked examples
An economy reduces unemployment from 5% to 3%. What typically happens to inflation?
When unemployment drops to 3%, labor markets tighten. Workers have more bargaining power, wages rise. Companies raise prices to cover higher labor costs. Inflation typically increases (e.g., from 2% to 4%).
A central bank raises interest rates to combat 6% inflation. What is the employment effect?
Higher rates cool spending and investment. Business hiring slows, unemployment rises. With fewer jobs available, wage pressure eases. Inflation falls to 3%, but unemployment may rise to 5%.
An economy faces 8% unemployment and 1% inflation. Which policy tradeoff should policymakers consider?
High unemployment = slack in the labor market, low inflation. Stimulating the economy (lower rates, more spending) could reduce unemployment to 5%. But inflation would likely rise to 3–4%. Policymakers must weigh job creation vs. price stability.

Common mistakes
The tradeoff is always the same strength. — Correct: The tradeoff shifts over time due to inflation expectations and structural changes in the economy.
We can achieve zero unemployment and zero inflation simultaneously. — Correct: The tradeoff shows they are competing goals; lowering one typically raises the other.
High unemployment always means low inflation. — Correct: The relationship is generally inverse, but stagflation (high inflation + high unemployment) has occurred.
The tradeoff applies equally to all time periods. — Correct: The Phillips Curve has shifted historically; the tradeoff weaker in the 1990s–2000s than the 1960s–70s.
FAQ
What is the inflation-unemployment tradeoff?
An inverse relationship: when unemployment falls, inflation tends to rise, and vice versa. Policymakers face a choice between lower unemployment and lower inflation.
What is the Phillips Curve?
A graph showing the empirical inverse relationship between inflation rates and unemployment rates, first documented by A.W. Phillips in 1958.
Why does the tradeoff exist?
When unemployment is low, labor is scarce, so workers demand higher wages. Employers raise prices to cover costs, pushing inflation up.
Can policymakers eliminate the tradeoff?
In the short run, no. But the strength of the tradeoff shifts with inflation expectations and supply shocks. Long-term, the curve can change position.
