La desigualdad económica regional en América Latina (1895-2010)
2020
En este artículo se analiza por primera vez el crecimiento y la evolución de la desigualdad regional a lo largo del proceso de desarrollo económico de nueve países de Latinoamérica (Argentina, Bolivia, Brasil, Chile, Colombia, México, Perú, Uruguay y Venezuela) entre 1895 y 2010. Para ello, en primer lugar se verifica la presencia de un proceso de beta-convergencia entre los países latinoamericanos para la totalidad del periodo. No obstante, se muestra cómo este proceso fue especialmente intenso durante los periodos en los que los diferentes Estados implementaron políticas activas de desarrollo (ISI) que favorecieron la convergencia entre las regiones de un mismo país. En segundo lugar, se …
Complementarity between human capital and public infrastructure in industrial comparative advantage
2021
The article examines the role of public capital as an infrastructure service in the acquisition of industrial comparative advantages. To achieve this in this framework, we develop a theoretical model highlighting the complementarity between public and human capital as a mechanism of industrial development, and test this idea using sectoral panel data from 1999 to 2014 across 35 advanced and less advanced countries. Our results show that the sustainable acquisition of a comparative advantage in the production of industrial goods can only be guaranteed by accumulating public capital and human capital. It shows that public infrastructure can only generate industrialization when it is made avai…
Use of marked strains of pathogenic (FOL8) and protective (FO47) Fusarium oxysporum to visualize their interactions with the tomato root in soil
2008
Several modes of action have been proposed to explain the biocontrol capacity of the Fusarium oxysporum protective strain Fo47, especially competition with the pathogen for root colonization. Confocal microscopy has been used to visualize the interactions between the ransformed strains and the tomato root in soil. A disinfested soil was infested by Fo47 GFP, Fol8 DsRed2, or both fungi together at several concentrations before transplanting tomato seedlings. The general pattern of soil and root colonization was similar for the two fungi, but the saprophytic development of Fo47 was faster than that of the pathogenic strain. Conidia, at the surface of soil particles, germinated as early as 18 …

Phenazine antibiotics produced by fluorescent pseudomonads contribute to natural soil suppressiveness to Fusarium wilt
2009
Natural disease-suppressive soils provide an untapped resource for the discovery of novel beneficial microorganisms and traits. For most suppressive soils, however, the consortia of microorganisms and mechanisms involved in pathogen control are unknown. To date, soil suppressiveness to Fusarium wilt disease has been ascribed to carbon and iron competition between pathogenic Fusarium oxysporum and resident non-pathogenic F. oxysporum and fluorescent pseudomonads. In this study, the role of bacterial antibiosis in Fusarium wilt suppressiveness was assessed by comparing the densities, diversity and activity of fluorescent Pseudomonas species producing 2,4-diacetylphloroglucinol (DAPG) (phlD+) …
Une analyse exploratoire des disparités régionales dans l'Europe élargie
2005
http://www.regionetdeveloppement.u-3mrs.fr/; National audience; L'objectif de cet article est d'analyser les inégalités régionales dans l'Union Européenne élargie à l'aide de l'Analyse Exploratoire des Données Spatiales appliquée aux PIB par tête des 258 régions de l'Europe des 27 sur la période 1995-2000. Les résultats montrent l'existence d'une forte autocorrélation spatiale globale et locale ainsi qu'une forte hétérogénéité dans la distribution des richesses. Ils montrent également un changement de polarisation, puisque l'élargissement conduit à un schéma de polarisation Nord-Ouest - Est à la place du schéma Nord-Sud traditionnellement mis en évidence dans la littérature. Finalement, cet…
Les effets macroéconomiques sur la productivité et les prix de vastes réformes structurelles sur les marchés des biens et du travail
2015
La présente analyse vise à caractériser les effets « directs » et « indirects » des régulations sur le marché des biens ainsi que les effets des régulations sur le marché du travail, sur la productivité et sur les prix. L’analyse est empirique et réalisée via des estimations sur un panel de quatorze pays sur la période 1987-2007, et quand cela est possible sur des donnés sectorielles (treize secteurs manufacturiers et cinq secteurs des services et réseaux). Au terme de ces estimations, il est possible de caractériser les effets de la mise en oeuvre de réformes structurelles. Les réformes structurelles consistent ici en une baisse des indicateurs de régulations sur les marchés des biens et d…
THE IMPACT OF FISCAL POLICY ON ECONOMIC GROWTH IN THE COUNTRIES OF EASTERN EUROPE
2015
This paper deals with the effects of fiscal policy on economic growth in 10 countries of Eastern Europe. For this analysis we to use two regression models. The results of the first model provide information on the factors that influence economic growth. Thus, direct taxes, indirect taxes, total income taxes, social contributions and the economic crisis had an effect on economic growth. Of these variables, total taxable income had a positive effect and indirect taxes and social contributions had a direct negative effect on economic growth. In the second model, the analysis confirmed that a significant effect on economic growth have had other direct taxes, social contributions of the employer…
Global Divergence in Growth Regressions
2013
This paper extends the standard growth regression model by adding an assumption that a country follows the global technology frontier either fully or partially. This additional assumption changes significantly the growth regression model and its results in three main ways. First, it shows that although a country converges to its long-run growth path, this path can diverge from the countries at the global frontier. We measure the degree of divergence for each country and find that most indeed diverge from the frontier. Second, we estimate growth dynamics without controlling for additional variables. Third, our new method enables us to disentangle the effects of the explanatory variables on t…
Firm Lifecycles and External Restructuring
2011
This paper studies how firms contribute to the productivity growth of an industry over their lifecycle. We present a decomposition method that allows us to condition the components of productivity growth on the age of production units. We find evidence for a prolonged positive exit effect that mirrors market selection during the early stages of firms lifecycle. This effect is tightly related to the negative initial productivity effect of entry. We also find some evidence that productivity-enhancing reallocation of resources between firms is concentrated on the middle aged firms.
