Appropriate technology in a Solovian nonlinear growth model
2007
We propose a Solovian growth model with a convex-concave production function and international technological spillovers. We test the empirical implications of the model, analysing the effects of the productivity slowdown that followed the oil shocks of the 1970s. We argue that this slowdown, altering the world income distribution, affected the pattern of international technological spillovers, taking the poorest countries further away from the technological leaders, and therefore unable to exploit their technologies. The result is the emergence of a poverty trap for low-income countries.
Growth and convergence in Africa: The impact of spatial effects
2010
The aim of this paper is to study the impact of spatial effects on convergence process in Africa over the period 1975-2000. Taking into account these effects through the methodology of Exploratory Spatial Data Analysis (ESDA) and spatial econometrics, we focus on the geographical dimension of economic convergence of African countries. This allows us to deal with spatial autocorrelation which is a consequence of econometric interdependences due to geographic spillovers. Indeed, countries economic performance hides specific geographical patterns providing information on the importance of location on economic dynamics. Our results prove the existence of convergence process in Africa through a …
On international spillovers
2012
Abstract This study investigates the role of international spillovers in generating productivity gains for a panel of 24 OECD countries during the period between 1971 and 2004. We use recent techniques developed in a common factor framework to characterize the global interdependence implied by international spillovers and the diffusion mechanisms involved. Consistently with some recent studies in this field, the evidence suggests that there are substantial cross-country spillovers mainly related to R&D and human capital variables, which contribute significantly to productivity.

A Contribution to the Schumpeterian Growth Theory and Empirics
2010
Soumis à Journal of Economic Growth; Document de Recherche LEO 2008-25; Cet article propose un cadre théorique et méthodologique unifie caractérisé par la priseen compte explicite des intéractions technologiques dans la modélisation des processus decroissance en adoptant une perspective Schumpétérienne. L'interdépendance globale impliquée par les spillovers internationaux de R&D doit être intégrée non seulement dans lamodélisation théorique mais également dans la spécification économétrique qui en découle.L'économétrie spatiale apparaît alors naturellement comme la méthodologie adéquate pourtraiter le problème de l'estimation de telles spécifications. Le modèle économétrique que nousproposo…
International R&D spillovers in the multi-country Schumpeterian growth model
2007
en ligne : http://ungaro.u-bourgogne.fr/pages/Documents%20de%20travail/Economie/e2007-04.pdf; Document de travail du LEG 2007-04; This paper reconsiders the multi-country Schumpeterian growth model and its empirical implications. We first show that the model implies a spatial econometric reduced form. Indeed, the global interdependence implied by international R&D spillovers needs to betaken into account in the theoretical model as well as in the empirical model. The spatial econometric model we propose includes the neoclassical growth model as a particular case. We can therefore test explicitly the role of R&D investment in the long run growth processagainst the Solow growth model which is…
Spatial spillovers in France: a study on individual count data at the city level
2007
Our study aims to measure the effects of spatial R&D spillovers on firms' patent production at the city level. We use an original method to estimate the spatial dimension of spillovers using count data. The method, based on a generalized cross entropy approach, allows us to test spatial auto-correlation. The main result is that when there are local spillovers, their impact on knowledge production is different according to the geographical area and the sector.
R&D with spillovers: Monopoly versus noncooperative and cooperative duopoly.
2011
This paper compares industry profit and R&D propensity for a duopoly conducting either noncooperative or cooperative R&D and a monopoly, using two different basic models of strategic R&D. One postulates spillovers in R&D inputs and predicts that equilibrium joint profit and R&D levels are always larger under monopoly. The other postulates spillovers in R&D outputs and sometimes predicts that joint profit and R&D levels are larger under either of the alternative scenarios. In addition, unlike input spillovers, spillovers in R&D outputs sometimes exert a positive effect on both effective and private noncooperative R&D levels.
