L'agglomération spatiale des firmes est un phénomène largement débattu en économie géographique. Cet article propose une nouvelle explication à ce phénomène : les entreprises mettent en avant la localisation comme un moyen de signaler un bien nouveau. Accepter la concurrence en se...

We propose a model where imperfect matching between firms and workers on local labor markets leads to incentives for spatial agglomeration. We show that the occurrence of spatial agglomeration depends on initial size differences in terms of both number of workers and firms. Allowing for dynamics...

This paper contributes to the economic analysis of merger control by taking into account the efficiency gains for the design of structural merger remedies when the competition authorities do not observe the magnitude of efficiency gains. We show that whenever divestitures are necessary, the...

Cet article développe un modèle théorique d'économie urbaine qui étudie les conséquences d'effets de voisinage informationnels sur l'organisation de la ville. Il s'agit, en particulier, d'examiner l'impact de tels effets de voisinage sur le processus de ségrégation urbaine. Pour ce...

This paper deals with the optimal enforcement of competition law between merger and anti-cartel policies. We examine the interaction between these two branches of antitrust, given the budget constraint of the public agency, and taking into account the ensuing incentives for firms in terms of...
