Matching Models Of Equilibrium Unemployment: An Overview

This paper aims to provide an overview of the labour market's benchmark macroeconomic models. The matching models of equilibrium unemployment are, in fact, the primary and most popular theoretical tools used by economists to evaluate various labour market policies and to study one of the key macroeconomic variables: The unemployment rate. It has been recognised that unemployment has also a structural nature which persists over the business cycle. The matching models, i.e. the models à la Mortensen-Pissarides, explain the co-existence in equilibrium of unemployment and vacancies through frictions in matching workers and firms.
