Are competitiveness rankings and institutional measures helping emerging economies to improve?
2022
Purpose – Based on the rankings of the global competitiveness index and the fragile states index, this paper aims to suggest alternative approaches to shed some light on the effectiveness of rankings in helping emerging economies improve their competitiveness from an institutional standpoint. Design/methodology/approach – The statistical analysis consisted of a two-stage analysis; the first stage consisted of constructing an updated Alternative Institutional Quality Index (AIQI), intending to design a comparative measure between dimensions over time. The second stage consisted of evidencing the structure of each of the observed dimensions' variance to evidence the existing changes or gaps o…
Modeling Spatial Data Pooled over Time: Schematic Representation and Monte Carlo Evidences
2015
The spatial autocorrelation issue is now well established, and it is almost impossible to deal with spatial data without considering this reality. In addition, recent developments have been devoted to developing methods that deal with spatial autocorrelation in panel data. However, little effort has been devoted to dealing with spatial data (cross-section) pooled over time. This paper endeavours to bridge the gap between the theoretical modeling development and the application based on spatial data pooled over time. The paper presents a schematic representation of how spatial links can be expressed, depending on the nature of the variable, when combining the spatial multidirectional relatio…
La valorisation des compétences de base sur le marché du travail français
2013
D’après la théorie du capital humain, les individus sont rémunérés selon leur productivité, productivité qui dépend elle-même du niveau de diplôme ou du nombre d’années d’études. Mais à l’heure où l’éducation certifiée est discutée comme filtre, qu’en est-il de la valorisation des compétences, notamment de base, sur le marché du travail français ? Alors que de nombreuses recherches ont déjà été réalisées à ce sujet (dans les pays anglo-saxons principalement), aucune n’a encore été conduite sur cette thématique en France. Cette présente étude cherche alors à déterminer, via un modèle d’Heckman en deux étapes, dans quelle mesure l’accès à l’emploi et les salaires sont expliqués par le niveau …
Stackelberg-Cournot and Cournot equilibria in a mixed markets exchange economy
2012
In this note, we compare two strategic general equilibrium concepts: the Stackelberg-Cournot equilibrium and the Cournot equilibrium. We thus consider a market exchange economy including atoms and a continuum of traders, who behave strategically. We show that, when the preferences of the small traders are represented by Cobb-Douglas utility functions and the atoms have the same utility functions and endowments, the Stackelberg-Cournot and the Cournot equilibrium equilibria coincide if and only if the followers’ best responses functions have a zero slope at the SCE.
Informatique et salaires : le cas de la France au travers de l'enquête sur les changements organisationnels et l'informatisation
2003
The strong tensions on the labour market met for these twenty last years have considerably accentuated the inequalities of wages to the detriment of the least qualified workers. One of the explanations of the increase in the inequalities on the labour maiket privileges a shock of the application for a job following the diffusion of the ICT in the economy. Thus, the introduction of newtechnologies into the production process or the operation of the companies would lead those to recruit worker more formed better with the detriment of the least qualified. But can one establish a link between the use of the ICT, in particular with computer, and the level of wage? The object of this article is t…
Controlled-by-owner firms, mobility of capital and microeconomic profit rate maximization
1999
When they actively control the firm, owners select the firm that has the best profit rate if the hypothesis of mobility of capital is adopted: controlled-by-owner firms are profit-rate-maximizing when sleeping-owner firms are pure-profit-maximizing. Both types are compared in monopoly, in perfect competition, in classical or in mixed duopoly. Always, controlled-by-owner firms have a lower output than comparable sleeping-owner firms. It only takes a fixed coefficient of equity capital to do that price plays no role for controlled-by-owner firms in perfect competition; in duopoly, it only takes a similar condition plus a linear demand to do that reaction functions vanish.

La production et valorisation des compétences sur le marché du travail : des approches néo-classiques à l'économie des conventions
2003
This research starts from human capital theory to study the production and valorization of competences in the labor market. Using the potentials and constraints of the neo-classical approach, the incorporation of other areas of economic science as well as other social sciences contributions are proposed. We believe that the key notions economics of education - human capital and wages, are necessary but they are inadequate to explain the level of individual competence or his level of remuneration. We propose a coherent integration of the theoretical and methodological tools of economics of education as well as of the economics of conventions and economics of human resources. And it includes …
Estimation des modèles dynamiques à erreurs composées avec autocorrélation par la méthode des variables instrumentales
1996
In this paper, we consider a dynamic error-components models with autocorrelated disturbances. We analyse the efficient estimation procedure of autocorrelation parameter and we try to find out whether moment conditions of a dynamic model without autocorrelation are valid when the model includes autocorrelation. We propose two efficient estimation methods of autocorrelation parameter in addition to Baltagi and Li (1994) estimator. We show that all moment conditions of a dynamic model without autocorrelation are not valid in dynamics errors-components models with autocorrelated disturbances.
Behaviour of common estimators in dynamic error-components models with autocorrelated disturbances
1997
The purpose of this paper is to make a presentation of the properties of a set of estimators comprising the within, between, OLS and GLS estimators in the study of dynamic error - components models with autocorrelated disturbances. We underline in this study the importance of the statistical distribution governing the initial values for the process and the structure of xit variable for the limiting values of the estimators when the temporal dimension is fixed but the individual dimension N grows indefinitly.
