Search & Matching (Beveridge Curve)
Unemployment as a matching problem: vacancies, job-finding rates, and the Beveridge curve.
The Search & Matching (Beveridge Curve) model, in writing
Definition
The modern theory of unemployment: workers and vacancies search for each other, matches form according to a matching function, and the Beveridge curve traces the vacancy-unemployment trade-off.
Matches = m(U, V) ; Beveridge curve: V falls as U rises along the cycle
The intuition
Hiring is not instant shopping: both sides search, screen, and settle, so vacancies and unemployment coexist. Booms slide the economy up the Beveridge curve (many vacancies, few unemployed); a structural mismatch (wrong skills, wrong cities) shifts the whole curve outward, meaning MORE unemployment at any vacancy level, the signature of a broken matching process.
Exam tip
Movement along the Beveridge curve = business cycle; outward shift = worse matching efficiency. Post-COVID data is the go-to modern example of an outward shift.
