Frictional unemployment is the component of total unemployment caused by the normal, ongoing process of workers and employers searching for each other. Unlike cyclical unemployment (driven by recessions) or structural unemployment (driven by mismatches between worker skills and available jobs), frictional unemployment exists even in a healthy economy and is generally considered unavoidable — and even beneficial, since it reflects voluntary mobility and better long-run matches between labor supply and demand.
Typical sources include:
- New graduates entering the labor market
- Workers voluntarily quitting to find a better fit
- People re-entering the workforce after caregiving, illness, or education
- Workers relocating geographically
- Seasonal transitions between industries
Economists treat frictional unemployment as part of the natural rate of unemployment, a concept developed by Milton Friedman and Edmund Phelps in the late 1960s. Because some search time is inherent to a dynamic labor market, full employment is not defined as zero unemployment; rather, it corresponds to a positive rate that includes frictional (and some structural) joblessness.
Search-and-matching models — most notably the Diamond–Mortensen–Pissarides (DMP) framework, which earned Peter Diamond, Dale Mortensen, and Christopher Pissarides the 2010 Nobel Prize in Economic Sciences — provide the standard theoretical treatment. These models analyze how vacancies, search effort, and wage bargaining produce equilibrium unemployment even without aggregate shocks.
Policy levers that influence frictional unemployment include unemployment insurance generosity (which can extend search duration), job-matching platforms and public employment services, and labor market information systems. Generous benefits may raise frictional unemployment modestly but can also improve match quality. In the United States, the Bureau of Labor Statistics does not publish frictional unemployment as a separate series; analysts typically infer it from short-duration unemployment data in the monthly Employment Situation report.
Example
In 2022, as U.S. quit rates hit record highs during the "Great Resignation," economists attributed much of the elevated short-duration unemployment to frictional churn rather than weak labor demand.
Frequently asked questions
Not necessarily. It reflects voluntary job search and labor mobility, which generally improve the quality of worker-employer matches and overall productivity.
