In this paper, we study the return to human capital variables for wages of workers observed in Tunisian matched worker-firm data in 1999. We develop a new method based on multivariate analysis of firm characteristics, which allows us most of the benefits obtained by introducing firm dummies in...

In this paper we analyze firms' ability to tacitly collude on pricesin an infinitely repeated duopoly game of vertical productdifferentiation. We show that firms collude if and only if their discountfactor is high enough, i.e. if they value future profits sufficiently. We alsoshow that a lower...

This paper searches for the determinants of government-funded R&D. The goal is to disentangle whether the efficiency considerations overwhelmingly emphasized by the theoretical literature are indeed the main driving force behind public R&D expenditures. Another goal of the paper is to assess...

Competition has long been regarded as productivity enhancing. Understanding the mechanism by which competition affects innovation and productivity is therefore an important topic for economic policy. The main contribution of this paper is to disentangle the relationship between competition and...

In this paper we propose a growth model in which the combined effect of human capital and technology adoption is the key factor in replicating and explaining growth miracles. Using standard technologies and parameterization, we show that the calibrated model generates output growth paths...

From Tunisian matched worker-firm data in 1999, we study the returns to human capital for workers observed in two leading manufacturing sectors. Workers in the mechanical and electrical industries (IMMEE) benefit from higher returns to human capital than their counterparts in the...

In this paper, we study the return to human capital variables for wages of workers observed in Tunisian matched worker-firm data in 1999. This reveals us how returns to human capital in a Less Developed Country like Tunisia may differ from the industrial countries usually studied with matched...

This paper presents a computable general equilibrium model of endogenous (stochastic) growth and cycles that can account for two key features of the aggregate data: balanced growth in the long-run and business cycles in the short-run. The model is built on Schumpeter's idea that economic...

This paper compares transitional dynamics in two alternative R&D non-scale growth models; one includes endogenous human capital, whereas the other does not. We show that focusing on the speed of convergence to discriminate between the two models can be misleading. Our analysis suggests that a...

In this paper we get the optimal two-part tariff contract for the licensing of a cost reducing innovation to a differentiated goods industry of a general size. We analyze the cases where the patentee is an independent laboratory or an incumbent firm. We show that, regardless of the number of...
