Informal job search through social networks and vacancy creation

Author

Listed:
  • Merlino, Luca Paolo

Abstract

In this paper I study the interaction between firms’ decisions to open vacancies and workers’ investment in social networks to find jobs. The transmission of information in the network generates positive search externalities so that in equilibrium vacancy creation and socialization are strategic complements. Despite this, there is a unique interior stable equilibrium.
