Book Description

This dissertation consists of three essays, each of which considers a different aspect of the moral hazard problem.




Moral Hazard and Risk Spreading in Medical Partnerships


Book Description

Partnerships provide a classic example of the tradeoff between risk spreading and moral hazard. The degree to which firms choose to spread risk and sacrifice efficiency incentives depends upon risk preferences, for which data are typically unavailable. The authors use a unique data set on medical group practice to investigate the degree to which firms which report more risk aversion have greater departures from first-best organizational incentive structures and the consequences for physician productivity. Increased risk aversion leads to compensation arrangements which spread more risk through diminished incentives. The authors also find that compensation arrangements that have greater degrees of revenue sharing across physicians significantly reduce each physicians's productivity, whereas reductions in group size significantly increase productivity. The estimated efficiency loss associated with risk aversion accounts for over ten percent of gross income, comparing the most risk averse to the least risk averse physicians in the sample. The authors use the results to show that changing the way physicians are paid from fee-for-service to capitation will dramatically reduce physician productivity.




Moral Hazard and Sorting in a Market for Partnerships


Book Description

We examine how equilibrium sorting patterns in a matching market for partnerships are impacted by the presence of bilateral moral hazard in a repeated production setting. We find that this impact depends on how the cost of moral hazard manifests itself - whether efficient effort is not feasible or desirable from the beginning, or whether inefficient effort is resorted to only as a punishment equilibrium. Which of these is the case depends both on the details of the technology and the contractual environment. In the former case, the presence of moral hazard moves the market away from positive sorting. In the latter case, whether moral hazard favors positive or negative sorting depends on how the power of incentives needed to implement effort varies with the observable types of the agents.










Public Private Partnerships and Public Works


Book Description

The subject of this paper is the role of what are termed Public Private Partnerships for investments in infrastructures and of the connected relationship between Public Administration and Enterprises, also in the light of Community law on Public Contracts and Concessions and of the recent coming into force in Italy of the Code of Public Contracts (Decree Law 163 of 2006). The aim is that of seeking mechanisms to improve the efficiency of single contracts by having recourse to the economic analysis law as a methodology of interpretation and, in particular, restoring the relationship between public administration and private partner to that of Principal-Agent. In this context the administration has to address basically two questions: in the first place, the selection of the private partner, and in the second place the stipulation of a potentially efficient contract, i.e. one able to induce the counterpart to bring its own interests into line with the administration's function of utility. Regarding the first question, the Public Private Partnership is considered also under the aspect of the potential elusiveness of the principles and rules of competition as sanctioned at Community level. To provide incentives for the involvement of private capital for public purposes, on the one hand, administrations are tending to seek new contractual figures and more streamlined and flexible award procedures for the selection of the private counterpart, while on the other hand the lawmaker is endeavouring to introduce legislation to facilitate the pursuing of this aim. The question is however that of establishing the limits of admissibility and the premises of legitimacy of this process in harmony with the over-riding principles, at Community level, of safeguarding competition and equality of treatment among the various entrepreneurs. A current example is what is happening in Italy for the adoption of the institution - already in force in Community law - of competitive dialogue. Once the private partner has been selected, it is in the administration's interest to stipulate a good contract, which will satisfy its own utility function and which will induce the counterpart, by foreseeing incentives and sanctions, to fulfill it exactly. The relationship of collaboration between public administration and enterprise is characterized by interests that are potentially at odds, stemming from a structural incompleteness of the contract due to various causes: the construction of a complex, long-lasting contractual relationship and the need, for the public partner, to have to renegotiate its behaviour with the private partner, involving high transaction costs. Furthermore, the fact that the relationship contains information asymmetries leads to distortional phenomena of moral hazard, necessitating high monitoring costs to be borne by the public administration, as the less informed party. These effects have to be analysed to seek possible adjustment mechanisms, on the one side by an adequate system of incentives and on the other an adequate system of control, aimed at the construction of a basically efficient relationship.
