Middlemen In Search Equilibrium

  • Adrian Masters

This article shows how allowing for goods to be divisible at the point of consumption and incorporating productive heterogeneity lead 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.
