Beveridge Curve

The Beveridge curve is a downward-sloping chart that plots the inverse relationship between the number of unfilled job vacancies and the unemployment rate in an economy. Named for British economist William Beveridge, it shows how quickly an economy can match jobless workers to available positions. A shift in the curve outward—more vacancies for the same unemployment level—suggests declining matching efficiency and rising structural unemployment.

The core inverse relationship

The Beveridge curve’s fundamental insight is straightforward: if unemployment falls, job vacancies should rise, and vice versa. When many workers are jobless and few positions are open, it is easy for employers to fill roles; the curve sits in the bottom-left quadrant with high unemployment and few vacancies. Conversely, when unemployment is very low and many jobs go unfilled, the curve shifts to the top-right, where employers struggle to find workers.

This relationship holds because in a normal, functioning labour market, the pool of available workers shrinks as unemployment falls, forcing employers to compete harder for talent. The curve captures this basic scarcity dynamic. Most economists treat the Beveridge curve as one of the labour market’s most reliable stylized facts—as consistent as supply and demand in any market.

What a shift in the curve means

The more important signal comes not from movement along the curve but from movement of the curve itself. In the 1960s and 1970s, the Beveridge curve was stable and predictable: you could forecast unemployment from vacancies, or vice versa. But starting in the late 1970s and repeatedly since, the curve has shifted outward—meaning that for any given unemployment rate, there are now more unfilled vacancies than the historical relationship would predict.

An outward shift is a red flag. It implies that even though unemployment is relatively high, employers cannot find suitable workers, and vacancies accumulate. This points to a breakdown in matching efficiency: the skills that unemployed workers possess no longer align with the skills jobs demand (skills mismatch), or workers are geographically misaligned with job clusters, or workers have exited the labour force entirely and are not counted as unemployed. This is the essence of structural unemployment—joblessness that cannot be cured simply by lowering interest rates and stimulating demand.

An inward shift—fewer vacancies for the same unemployment rate—suggests the opposite: the labour market is becoming more efficient at matching workers to jobs, or overall demand is cooling, or workers are returning to the labour force.

Shifts since 2020

The Beveridge curve provided crucial context during the 2020s labour market recovery. After the pandemic, the curve shifted sharply outward: unemployment fell rapidly, but job vacancy rates soared and remained stubbornly high for months. The ratio of vacancies to unemployed workers (the V/U ratio) reached levels not seen since the 1960s. Economists debated the cause: Did workers lack the right skills? Had they relocated? Were expanded unemployment benefits keeping them out of the labour force? Or were employers simply demanding higher wages than workers were willing to accept?

This period illustrated the Beveridge curve’s most important modern use: as an early-warning system for structural unemployment and wage pressure. When the curve shifts outward significantly, central banks and policymakers recognize that simply reducing unemployment further through monetary stimulus will not solve the matching problem; instead, it will bid up wages and fuel inflation.

The V/U ratio and policy implications

The vacancy-to-unemployment ratio—dividing the vacancy rate by the unemployment rate—is a cleaner way to track curve shifts. A V/U ratio of 1 means one job opening for each unemployed person. Ratios above 1 (common in tight labour markets) signal that unfilled vacancies exceed the unemployed workforce; in principle, every jobless person could find work if skills and location aligned perfectly. Ratios below 0.5 suggest slack in the labour market and little wage pressure.

Central banks and labour economists watch the V/U ratio because it influences inflation expectations. A high ratio hints at wage pressure despite measured unemployment, because employers bid aggressively for scarce labour. This was evident in the post-2020 period, when wage growth accelerated and inflation rose even as unemployment remained elevated—exactly the scenario Beveridge curve shifts had predicted.

Measurement challenges and data gaps

The Beveridge curve’s reliability depends on accurate vacancy and unemployment data. Many economies lack comprehensive job-vacancy counts; the United States relies on the Job Openings and Labor Turnover Survey (JOLTS), which is itself subject to seasonal adjustments and revision. Unemployment data is broader but also subject to measurement issues—workers who have given up searching drop out of the labour force and are not counted as unemployed, distorting the relationship.

A sudden shift in how vacancies or unemployment are measured—a change in methodology or scope—can create the false appearance of a Beveridge curve shift when no real change in matching efficiency has occurred. Economists must therefore combine curve analysis with deeper inspection of labour-force participation, wage growth, and sectoral mismatches.

Structural versus cyclical shifts

Economists distinguish between cyclical movements—small shifts along the curve during normal business-cycle ups and downs—and structural shifts, which are sustained outward movements indicating permanent changes in matching efficiency. Most agree that the curve shifts of the late 1970s and 2020s were largely structural, reflecting shifts in industry composition, geographic concentration of jobs, education gaps, and barriers to mobility. These shifts are harder for monetary policy to address and often require fiscal policy, training programs, or sectoral rebalancing.

Beveridge curve and policy trade-offs

The Beveridge curve illustrates a painful policy trade-off: in the presence of structural unemployment (an outward-shifted curve), policymakers cannot achieve low unemployment without igniting inflation through wage bidding. Conversely, a policy aimed solely at reducing inflation through demand destruction (higher interest rates, layoffs) will leave structural unemployment and vacancies unresolved.

This is why modern policymaking increasingly pairs demand-side monetary policy with supply-side interventions: education, retraining, housing policy, and labour-market infrastructure—all aimed at shifting the Beveridge curve back inward.
