This paper aims to contribute to the normative economic analysis of mergers control by taking into account the possible efficiency gains for the design of structural merger remedies. We show that a larger asset transfer should be requested from a less efficient merged firm than from a more...

This paper aims to contribute to the normative economic analysis of mergers by taking into account the possible efficiency gains for the design of structural merger remedies. We show that a larger asset transfer should be requested from a less efficient merged firm than from a more efficient...

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...

I analyze a market where there is a homogeneous good, which quality is chosen, and therefore known, by a single producer. Consumers do not know the quality of the good but they use their acquaintances in order to obtain information about it. Information transmission exhibits decay and consumers...

This paper examines the optimal non linear income and commodity tax when the same labor disutility can receive two alternative interpretations, taste for leisure and disability, but the disability is not readily observable. We compare the optimal policyunder alternative social objectives,...

Individuals exchange contracts for the deliveryof commodities in competitive markets and, simultaneously, act strategically; actions affect utilities across individuals directlyor through the payoffs of contracts. This encompasses economies with asymmetric information. Nash-Walras equilibria...

We study the efficiency of the equilibrium price in a centralized, orderdriven market where many asymmetrically informed traders are active for many periods. We show that asymmetries of information can lead to suboptimal information revelation with respect to the symmetric case. In particular,...

Asymmetric information concerns either commodities or mutually exclusive states of the world. The notion of competitive equilibrium differs between the two cases. In particular, incentive compatibility constraints are only relevant in the case of asymmetric information concerning mutually...

This paper examines the properties of the optimal nonlinear income tax when preferences are quasilinear in leisure and heterogeneous. Individuals differ in their ability and in their preferences for leisure. The government seeks to redistribute income. It can perfectly observe the level of...
