We consider an optimal regulation model in which the regulated firm’s production cost is subject to random, publicly observable shocks. The distribution of these shocks is correlated with the firm’s cost type, which is private information. The regulator designs an incentive compatible...

We study the impact of access regulation in a telecommunications market on an entrant?s decision whether to invest in a network or ask for access when the regulator cannot observe its potential demand. Since the entrant has incentives to not compete vigorously right after entry in order to...

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...

In this paper we consider the problem of regulating an open access essential facility. A vertically integrated firm owns an essential input and operates on the downstream market under the roof of a regulatory mechanism. There is a potential entrant in the downstream market. Both competitors use...

This article studies the problem of regulating a monopolist with unknown marginal cost. The originality of the paper is to consider that the regulator faces a cash-in-advance constraint. The introduction of such a constraint not only reduces the amount of public good provided but also limits the...

The paper develops a model of decentralized metering decisions when selective metering is socially optimal. Households choose between two-part tariffs. Decentralization achieves social efficiency when the regulator, who knows household characteristics, gives household-specific compensation (via...

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. The second...

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...

This paper investigates the design of incentives in a dynamic adverse selection framework when agents' production technologies display learning effects and agents' rate of learning is private knowledge. In a simple two-period model with full commitment available to the principal, we show that...
