A  curse of dimensionality  arises when using the Continuum-GMM procedure to estimate large dimensional models. Two solutions are proposed, both of which convert the high dimensional model into a continuum of reduced information sets. Under certain regularity conditions, each reduced...

A review of the theoretical properties of the GMM with a continuum of moment conditions is presented. Numerical methods for its implementation are discussed. A simulation study based on the stable distribution and an empirical application based on the autoregressive variance Gamma model are...

This paper explores the indirect inflationary mechanism allowed by loss-leaders banning laws. In a model where a monopolist producer sells his product through vertically separated and differentiated retailers, we show that the ban of loss-leading can be used strategically by the producer to...

[fre] Nous examinons l’impact des structures de marché sur la variété des produits, lorsque le coût de lancement d’un nouveau produit est fixe et réparti entre les secteurs de production et de distribution. Une chaîne intégrée verticalement offre alors une plus grande variété de...

This paper studies horizontal mergers in vertically related markets. In a two-level Cournot model, with an intermediate and a final market, we show that downstream mergers inducing size effects are, ceteris paribus, more profitable than upstream ones. Moreover, a merger at one level reduces the...
