We study the optimal regulation of a monopolist when intrinsic efficiency (intrinsic cost) and empire building tendency (marginal utility of output) are private information, but actual cost (the difference between intrinsic cost and effort level) is observable. This is a problem of...

We determine the optimal contract for the regulation of a bureaucratic firm in the case in which the bureaucratic bias is firm's private information. We find that output is distorted upward when the bureaucratic bias is low, downward when it is high, and equals a reference output when it is...

We study regulation of a bureaucratic provider of a public good in the presence of moral hazard and adverse selection. By bureaucratic we mean that it values output in itself, and not only profit. Three different financing systems are studied - cost reimbursement, prospective payment, and the...

We obtain the optimal contract for the government (principal) to regulate a manager (agent) who has a taste for empire-building that is his/her private information. This taste for empire-building is modeled as a utility premium that is proportional to the difference between the contracted output...

This paper studies exchange economies in which agents have differential information about the goods that the other agents bring to the market. To study such a setting, it is useful to distinguish goods not only by their physical characteristics, but also by the agent that brings them to the...

We study the distribution of a fixed amount of "favors" by an incumbent politician between two pressure groups, each of them offering to the agent a campaign contribution contingent on the quantity of "favors" received. Assuming that the total amount supplied is a private information of the...
