We survey search-theoretic models of the labor market and discuss their usefulness for analyzing labor market dynamics, job turnover, and wages. We first examine single-agent models, showing how they can incorporate many interesting features and generate rich predictions. We then consider equilibrium models that endogenize several variables that are treated parametrically in single-agent models, including the arrival rate of job offers and the wage distribution. We survey alternative formulations of these models, emphasizing two key issues: how workers and firms meet, and how wages are determined. We emphasize throughout the implications of alternative assumptions for turnover, wage dispersion, and efficiency.
