In an industry where regulated firms interact with unregulated suppliers, we investigate the welfare effects of a merger between regulated firms when cost synergies are uncertain before the merger and their realization becomes private information of the merged firm. The optimal merger policy...

We study the regulation of a monopolistic firm that provides a non-marketed output based on multiple substitutable inputs. The regulator is able to observe the effectiveness of the provision, but faces information asymmetries with respect to the efficiency of the firm’s activities. Motivated...

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...

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...

I compare certification and self-regulation, two widely used quality assurance mechanisms in markets where consumers do not observe the quality of goods. Certification is a mechanism in which an external firm offers a certificate to producers who undergo a testing procedure, issues the...

I study the question of how much product information should be available to consumers. A monopolist sells one unit of product. The consumer is initially uninformed of the product value but can incur costs to observe a noisy signal of his valuation. I show that consumer surplus can be increasing...

We consider a principal-agent model where the principal can monitor and punish the agent with a fine if the agent is caught being non-compliant. To reduce the probability of being verified, the agent can engage in costly avoidance. We design the optimal regulatory policies with and without avoidance
