Monotone Concave Operators: An application to the existence and uniqueness of solutions to the Bellman equation
2008
We propose a new approach to the issue of existence and uniqueness of solutions to the Bellman equation, exploiting an emerging class of methods, called monotone map methods, pioneered in the work of Krasnosel’skii (1964) and Krasnosel’skii-Zabreiko (1984). The approach is technically simple and intuitive. It is derived from geometric ideas related to the study of fixed points for monotone concave operators defined on partially order spaces.
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…
Global Dynamics and Imbalance Effects in the Lucas-Uzawa Model: Further Results
2007
In this paper we use a new analytical approach to the Lucas-Uzawa model (Boucekkine and Ruiz Tamarit, 2007) to extend the existing results on the dynamics, and notably on the imbalance effects arising in the model. The approach does not only allow to extend the traditional analysis to any initial conditions and for all variables in level, but it also permits a more general investigation of imbalance effects.
The impact of classes of innovators on Technology, Financial Fragility and Economic Growth
2011
In this paper, we study innovation processes and technological change in an agent-based model. By including a behavioral switching among heterogeneous innovative firms, which can endogenously change among three different classes (single innovators, collaborative innovators and imitators) on the base of their R&D expenditures, the model is able to replicate, via simulations, well known industrial dynamic and growth type stylized facts. Moreover, we focus the analysis on the impact of these three innovation categories on micro, meso and macro aggregates. We find that collaborative companies are those having the highest positive impact on the economic system. The model is then used to study th…
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…
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.

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…
NATIONAL COMPETITIVENESS - SCENARIOS FOR ROMANIA
2012
Competitiveness remains a continuous concern of nations in any stage of development, from factor based economy to innovation based economy. The present paper aims to emphasize the current level of national competitiveness of Romania, on one hand, and to identify possible ways to improve the current level by building scenarios in order to eliminate the uncertainty, on the other hand. The paper proposes four scenarios for increase GCI (growth competitiveness index) and four scenarios from pessimistic point of view (in these scenarios GCI will be decrease). In the near future, Romania must improve their pillars of national competitiveness and must increase their GDP per capita for transition p…
