This paper provides an empirical application of Lee and Pitt’s (1986) approach to the problem of corner solutions in the case of panel data. This model deals with corner solutions in a manner consistent with the firm behavior theory while controlling for unobserved heterogeneity. In this...

Usually firms operate with a restricted number of energy sources. In the dairy industry, most firms have multi-energy systems allowing them to shift from one energy source to another at almost no cost. Zero expenditures are observed because firms minimize costs and non-negativity constraints on...

We estimate Translog and Fourier forms for three sectors of the French economy. The hypothesis that the former can be reduced to the latter is highly rejected. We show that the hypothesis of an endogenous technical change drops the autocorrelation of the disturbances in the Fourier case only....

This paper examines the link between pollution and income. The main purpose is to assess whether the introduction of income inequality in a Environmental Kuznets Curve (EKC) analysis can give new insights into the relationship between pollution and economic growth. The EKC hypothesis proposes...

[fre] Nous proposons un modèle économétrique, basé sur la théorie micro-économique du producteur, permettant d'estimer un système de fonctions de demande en présence de dépenses nulles. Dans l'analyse empirique nous estimons une fonction de coût translog pour trois facteurs...
