Default and renegotiation : financial structure and incentive in public-private partnership contracts

This research explores the functional relationship between financial structure and agent's cost-reducing effort in the realm of public-private-partnership (PPP) contracting. I consider a canonical contracting problem where incomplete financial provisions are used to govern the execution of a project that involves uncertain cost. The existing literature shows that debt (as opposed to external equity) is the better financing alternative in terms of effort induction. I show, on the other hand, that internal equity (as opposed to debt) is the better financing alternative for effort induction when the parties are allowed to achieve ex post Pareto improvement through self-enforcement, renegotiation, and replacement. Under the assumptions that the consumer surplus is always greater than the realized cost, and that the social cost of public funds (the tax rate) is greater than the private agent's cost of capital, I show that: (1) Ex ante capital structure and control rights regime jointly determine the equilibrium game form of the contract (the agent's effort level and the uncertainty of cost don't matter). (2) The agent's optimal cost-reducing effort is determined by a hold-up factor and a self-enforcement factor. The former is a strict disincentive to the agent's effort, whereas the latter can be an incentive or a disincentive to the agent's effort depending on the capital structure of the contract.
