Multiple lending and constrained efficiency in the credit market


  • ATTAR, Andrea
  • CAMPIONI, Eloisa
  • PIASER, Gwenaël


In this paper we present a model of credit market with several homogeneous lenders competing to finance an investment project. Contracts are non-exclusive, hence the borrower can accept whatever subset of the offered loans. We use the model to discuss efficiency issues in competitive economies with asymmetric information and non-exclusive agreements. We characterize the equilibria of this common agency game with moral hazard and show that they all belong to the constrained Pareto frontier.
