This paper analyses the effect of antidumping (AD) duties on the pricing behaviour of exporters targeted with these measures. Using product and firm-level data for South Korea, the study provides evidence of increased export unit values and firms’ markups following the imposition of AD ad...

In the theoretical literature, strong arguments have been provided in support of the efficiency defense in antitrust merger policy. One of the most often cited results is due to Williamson (1968) that shows how relatively small reduction in cost could offset the deadweight loss of a large price...

L’efficacité des partenariats public-privé (PPP) dans les industries de service public en réseau a été remise en cause par de nombreux auteurs. Une des défaillances majeure reprochée à ce type d’accords concerne le manque d’incitation de l’opérateur en place à investir en fin...

Nous étudions l’ouverture à la concurrence d’un bien réseau dans lequel l’opérateur historique, intégré verticalement, gère en monopole l’infrastructure et est concurrencé sur le secteur des services. La qualité du bien réseau est le minimum des qualités de chaque composante....

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 effectiveness of antitrust policy in fighting horizontal collusion under different regimes of policy implementation. We consider two regimes : a public agency regime, where an antitrust authority is in charge of competition policy, and a "delegation" regime, where the...

A benevolent social planner which faces a cost of public funds because of distortive taxation, wants to finance an upstream monopoly. This monopoly produces a necessary input for a downstream competitive sector which competes à la Cournot (with either a fixed number of firms or free entry in...

We investigate positional effects in a vertically differentiated duopoly, evaluated against the first best. Positional concerns distort the allocation of consumers across varieties, as well as the average quality. If the external effect is sufficiently relevant, the resulting welfare loss is...

We study the welfare impact of enforcing a competitive behavior from an unregulated fringe competing with a regulated dominant operator with imperfectly differentiated goods. The fringe is potentially collusive but may be supervised by a competition authority. We show that the...

The paper discusses the relation between the justly famous Hotelling’s [1929] paper on stability in competition and the corresponding passages of the often ignored Launhardt’s [1885] book, devoted to mathematical economics. Launhardt is sometimes credited for the anticipation of...
