[eng] Studying differentiated product markets has become one of the main topics in New Empirical Industrial Organization. This paper presents different methodological approaches that have been used. It stresses on their pros and cons according to the type of available data and the features of...

Publiée par la Commission européenne, l’étude examine l’évolution économique et technique du marché de l’édition scientifique en Europe. Elle a été commandée dans le cadre du débat public actuel sur les conditions d'accès aux publications scientifiques et sur leur diffusion....

This paper deals with the forest owner's attitude towards risk and the harvesting decision in several ways. First, we propose to characterize and quantify the forest owner's attitude towards risk. Second, we analyze the determinants of the forest owner's risk attitude. Finally, we determine the...

Using a stochastic dynamic programming model we analyze how French private forest owners make inter-temporal trade-offs between non-timber amenities and timber income. We explicitly take into account the price expectations and forest growth. In addition, unlike previous empirical studies...

We study a spatial competition model which is a variant of the celebrated Hotelling (1929) framework. One of the firm is a brick-and-mortar one while the other is on-line. Both firms sell the same product except that (constant) marginal costs may differ. Consumers going to the shop around the...

We propose a two-step semiparametric pseudo-maximum likelihood procedure forsingle-index regression models where the conditional variance is a known function of theregression and an additional parameter. The Poisson single-index regression model withmultiplicative unobserved heterogeneity is an...
