Middlemen in Search Equilibrium

Author

Listed:
  • Adrian Masters

Abstract

This paper shows how including divisibility of goods and productive heterogeneity leads to the emergence of middlemen in an equilibrium search environment. In the baseline model, middlemen are welfare reducing and their number increases as market frictions are reduced. When the model is extended to allow for time taken in production and increasing returns-to-scale in the market meeting technology, middlemen can be beneficial to society by speeding up the meeting process.
