This paper presents a model for estimating both the magnitude of price-cost margins and the extent of rent sharing. The model generalizes Robert Hall's model, relating the conventional measure of total factor productivity (the "Solow residual") to the degree of imperfect competition in product...

This paper is an attempt to assess the existence and magnitude of local research spillovers in France. We rely on the model of an extended production function (Cobb-Douglas and Trans log) with both local and neighborhood R&D capital stocks. We estimate this model on 312 employment areas as of...

Our two related goals in this paper are the following: Firstly and mainly, we want to examine the effects of major changes in modelling strategy and econometric methodology, over the past twenty years, on estimation of firm-level investment equations using panel data. Secondly, we try to assess...

This paper consists in a detailed robustness investigation of the Crépon, Duguet and Mairesse [1998] (CDM) econometric framework, which encompasses as a reduced form equation the production function extended to R&D, as pioneered by Zvi Griliches. We focus on the sensitivity of the estimated...
