This article studies the problem of regulating a monopolist with unknown marginal cost. The problem described differs from Baron and Myerson [1982] because we suppose that the regulator faces a cash-in-advance constraint. The introduction of such a constraint may lead to the collapse of the...

In this paper we consider the problem of financing infrastructure when the regulator faces a budget constraint. The optimal budget-constrained mechanism satisfies four properties. The first property is bunching at the top, that is the more efficient firms produce the same quantity irrespective...

This paper presents a game where the incumbent firm uses the price as a signal about demand size. Without observing the demand, the regulator has to decide if the entry of new firms will be allowed. The game has a pooling Perfect Bayesian Equilibrium in which the incumbent firm chooses the...

In this paper we compare the costs of two regulatory policies about the entry of new firms. We consider an incumbent firm that has more information about the market demand than the regulator. Then, the incumbent firm can use this advantage to persuade the regulator to make entry more difficult....

Since 1989 and the regionalization of public transports in Belgium, the Société des transports intercommunaux de Bruxelles (STIB), i.e. the public operator of urban transport in Brussels, has undergone many changes, both structural and organizational. Meanwhile, the company has managed to...

Some empirical works from the nineties have shown the existence of a negative relationship between inequality and growth. In this paper I show that the inefficiency of the Public Sector due to agency problems can be a new element that must e considered to explain the negative empirical...

I demonstrate that providing information about product quality is not necessarily the best way to address asymmetric information problems when markets are imperfectly competitive. In a vertical differentiation model I show that a Minimum Quality Standard, which retains asymmetric information,...
