In the entry literature, researchers sometimes use revenues as a proxy for profits because this is the only data available. Doing so could seriously bias the results.

The Poisson regression (PR) model is inappropriate for modeling over- or under-dispersed (or inflated) data. Several generalizations of PR model have been proposed for modeling such data. In this paper, a rich family of generalized Poisson regression (GPR) models is reviewed in detail. The...

We study the determinants of the demand of cultural goods using two different approaches. Starting by a simple analytical model that deals with the optimal demand of cultural goods for a consumer that lives two periods, we investigate the relevance of cultural capital on taste formation. Some...

This paper compares the practical performance of alternative goodness-of-fit techniques for count data models in the context of a study of the determinants of demand for dental care in Spain. We apply alternative goodness-of-fit techniques to different specifications. In particular, we implement...

This paper contributes to job-search literature by analysing commuter behaviour in the presence of asymmetric changes in the wage distribution. Job search theory predicts that reservation wages increase with the mean and mean-preserving spread of the wage distribution. However, changing...
