This article presents an equilibrium model of a dual labor market. Firms are assumed to be identical ex ante and dualism arises endogenously. The dual labor market outcome is supported by efficiency wage and search considerations. Firms choose wage/effort requirement packages optimally given optimal search and effort choice by workers, and vice versa. The authors prove existence and investigate the occurence and nature of dual labor market equilibria. Copyright 1992 by University of Chicago Press.
