This paper studies informational externalities between contracts. Two principals (for instance the governments of two neighbouring countries) deal with two different agents (for instance a railway company in each country). If, in the first period, an agent refuses the contract offered by his...

This paper characterizes the equilibrium sets of an intrinsic common agency game with discrete types and direct revelation mechanisms. After presenting a general algorithm to find the pure-strategy equilibria of this game, we use it to characterize these equilibria when the two principals...

This paper derives an Equivalence Principle between organizational forms of supervisory and productive activities. We consider an organization with an agent privately informed on his productivity and a risk averse supervisor getting signals on the agent's type. In a centralized organization, the...

We make three contributions to the theory of contracting under asymmetric information. First, we establish a competitive analog to the revelation principle which we call the implementation principle. This principle provides a complete characterization of all incentive compatible, indirect...

Public-private partnerships (PPPs) cannot be justified because they free public funds. When PPPs are justified on efficiency grounds, the contract that optimally balances demand risk, user-fee distortions and the opportunity cost of public funds, features a minimum revenue guarantee and a...

Evidence from ongoing procurement and concession contracts shows that time overruns are widespread. Two key elements, among others, can affect the delays in the execution of the contracts: a) uncertainty over production costs; b) inefficiency in the judicial system. In this article we summarize...
