    Based on previous experience in Southern Europe and Middle-East, potentiality and constraints in collaborative projects are presented. More specifically, a number of EC funded ICT projects, undertaking by countries of these regions and implemented the last seven years, are presented in brief. By the introduction of quality issues and carefully examining a number of constraints and difficulties appeared during the development of these projects, we propose specific recommendations for successful co-operation, especially at a moment of deep and strong changes in these regions.</jats:p

    Measuring Poverty and Inequality in a Computable General Equilibrium Model

    This paper aims to evaluate the relevance of different types of macroeconomic general equilibrium modelling for measuring the impact of economic policy shocks on the incidence of poverty and on the distribution of income. In the literature three approaches are identified. The first is based on a traditional form of the CGEM which specifies a large number of households. In this case, we can only observe inter group income inequalities. The next uses survey data to estimate the distribution function and average variations by group, which allows one to estimate the evolution of poverty. The third approach, which we present in detail, includes individual data directly in the general equilibrium model according to the principles of micro simulations. This treatment provides a more reliable picture of income distribution but is also more complex. Given this, we develop, within a co-ordinated statistical framework representing an archetypal economy, the three types of model described above. More precisely, this exercise allows us to break down the contribution of average income variations, of the poverty line, and of income distribution in the evolution of the main poverty indicators. The results obtained show the importance of intra group information and therefore the relevance of micro simulation exercises.General Equilibrium Models, Micro Simulation, Poverty, Inequality

    Physicians' Multitasking and Incentives: Empirical Evidence from a Natural Experiment

    We analyse how physicians respond to contractual changes and incentives within a multitasking environment. In 1999 the Quebec government (Canada) introduced an optional mixed compensation system, combining a fixed per diem with a discounted (relative to the traditional fee-for-service system) fee for services provided. We combine panel survey and administrative data on Quebec physicians to evaluate the impact of this change in incentives on their practice choices. We highlight the differentiated impact of incentives on various dimensions of physician behaviour by considering a wide range of labour supply variables: time spent on seeing patients, time devoted to teaching, administrative tasks or research, as well as the volume of clinical services and average time per clinical service. Our results show that, on average, the reform induced physicians who changed from FFS to MC to reduce their volume of (billable) services by 6.15% and to reduce their hours of work spent on seeing patients by 2.57%. Their average time spent per service increased by 3.58%, suggesting a potential quality-quantity substitution. Also the reform induced these physicians to increase their time spent on teaching and administrative duties (tasks not remunerated under the fee-for-service system) by 7.9%.Physician payment mechanisms, multitasking, mixed-payment systems, incentive contracts, labour supply, self-selection, panel estimation

    Ce papier vise Ă  Ă©valuer la pertinence des diffĂ©rents types de modĂ©lisation macro- Ă©conomique en Ă©quilibre gĂ©nĂ©ral pour mesurer l'impact des chocs de politique Ă©conomique sur l'incidence de la pauvretĂ© et la distribution du revenu. Dans la littĂ©rature on peut identifier trois types d'exercices. Le premier repose sur une forme traditionnelle de MEGC spĂ©cifiant un grand nombre de mĂ©nages. Dans ce cadre on peut seulement observer les inĂ©galitĂ©s de revenu inter groupe. Le suivant utilise des donnĂ©es d'enquĂȘte pour estimer la fonction de distribution et lui applique les variations moyennes par groupe, ce qui permet d'estimer l'Ă©volution de la pauvretĂ©. Le dernier enfin, que nous prĂ©sentons plus en dĂ©tail, inclus les donnĂ©es individuelles directement dans le modĂšle d'Ă©quilibre gĂ©nĂ©ral selon le principe des micro simulations. Cette approche donne une image plus fidĂšle de la distribution de revenu mais est Ă©galement plus complexe Ă  mettre en Ɠuvre. Dans cette perspective, nous dĂ©veloppons les trois types de modĂ©lisation prĂ©cĂ©demment dĂ©crits, dans un cadre statistique coordonnĂ© reprĂ©sentant une Ă©conomie archĂ©type. Plus prĂ©cisĂ©ment, cet exercice nous permet de dĂ©composer la contribution des variations de revenu moyen, de la ligne de pauvretĂ© et des distributions de revenu dans l'Ă©volution des principaux indicateurs de pauvretĂ©. Les rĂ©sultats obtenus dĂ©montrent l'importance des informations intra groupe et donc la pertinence des exercices de micro simulation.ModĂšles d'Équilibre GĂ©nĂ©ral, Micro simulation, PauvretĂ©, InĂ©galitĂ©

    Assessing the tribocorrosionnext term behaviour of Cu and Al by electrochemical impedance spectroscopy

    International audienceThis study is focused on the interests and limits of Electrochemical Impedance Spectroscopy, to establish the electrochemical behaviour of a tribosystem between Cu and Al, in acid solution. The calculated capacitance, in high-frequency range, partially allows understanding the double layer state of body in the contact. The Potential of Zero Charge (PZC) was calculated for Cu sample and it was associated with a potential range for Al. PZC value of each material is discussed as a key parameter of sliding contact. During tests of wear, the EIS results are related to the evolution of adsorbed water molecules

    Copper and aluminium tribocorrosion in acid medium : Electrochemical Impedance Spectroscopy investigations

    International audienceThis study is focused on the interests and limits of EIS, Electrochemical Impedance Spectroscopy, to establish the electrochemical behaviour of a tribosystem during friction between copper and aluminium in acid solution. EIS measurements are performed before, during and after friction for understanding electrochemical surface reaction evolution. For each material, calculated capacitance in high frequencies range allows getting further information about the double layer state. The Potential of Zero Charge (PZC) is defined such as the potential value associated to the lowest capacitance. PZC was calculated for copper sample precisely and it was associated to a potential range for aluminium. PZC value of each material is discussed as a key parameter of sliding contact in considered media. Finally, impedance diagrams illustrate a parallel contribution of aluminium and copper during static contact. During wear corrosion tests, EIS results, at high frequencies, are related to the evolution of adsorbed water molecules

    We analyse how physicians respond to contractual changes and incentives within a multitasking environment. In 1999 the Quebec government (Canada) introduced an optional mixed compensation system, combining a xed per diem with a partial (relative to the traditional fee-for-service system) fee for services provided. We combine panel survey and administrative data on Quebec physicians to evaluate the impact of this change in incentives on their practice choices. We highlight the dierentiated impact of incentives on various dimensions of physician behaviour by considering a wide range of labour supply variables: time spent on seeing patients, time devoted to teaching, administrative tasks or research, as well as the volume of clinical services and average time per clinical service.

Their average time spent per service increased by 3.81%, suggesting a potential quality-quantity substitution. Also the reform induced these physicians to increase their time spent on teaching and administrative duties (tasks not remunerated under the fee-for-service system) by 7.9%. En 1999, le ministĂšre de la SantĂ© et des Services Sociaux du QuĂ©bec introduisait un mode de rĂ©munĂ©ration mixte optionnel pour rĂ©munĂ©rer l’activitĂ© hospitaliĂšre des mĂ©decins spĂ©cialistes. Ce mode combine une rĂ©munĂ©ration forfaitaire pour chaque jour de travail (per diem ou demi per diem) et une rĂ©munĂ©ration partielle Ă  l’acte s’exprimant en un pourcentage du tarif habituellement applicable pour un service donnĂ©. Cette Ă©tude jumelle en panel des donnĂ©es de sondage du CollĂšge des MĂ©decins du QuĂ©bec et des donnĂ©es administratives de la RĂ©gie de l’assurance maladie du QuĂ©bec pour Ă©valuer l’impact de ce mode de rĂ©munĂ©ration sur les choix de pratique des spĂ©cialistes. Nous mettons l’accent sur l’effet de la rĂ©munĂ©ration mixte sur plusieurs dimensions du comportement professionnel du mĂ©decin : heures consacrĂ©es aux patients, heures consacrĂ©es Ă  l’enseignement, aux activitĂ©s mĂ©dicales administratives et Ă  la recherche, volume de services mĂ©dicaux et temps moyen par service mĂ©dical. Nos rĂ©sultats montrent que l’introduction de la rĂ©munĂ©ration mixte a incitĂ© les mĂ©decins qui sont passĂ©s de la rĂ©munĂ©ration Ă  l’acte Ă  la rĂ©munĂ©ration mixte Ă  rĂ©duire leur nombre de services mĂ©dicaux (facturables) de 6,15 % et Ă  rĂ©duire leurs heures de travail consacrĂ©es aux patients de 2,57 %. En revanche, le temps moyen par service mĂ©dical s’est accru de 3,81 %, ce qui peut suggĂ©rer une substitution entre la quantitĂ© et la qualitĂ© des services. La rĂ©forme a aussi incitĂ© ces mĂ©decins Ă  accroĂźtre le temps consacrĂ© Ă  l’enseignement et aux activitĂ©s mĂ©dicales administratives (activitĂ©s non rĂ©munĂ©rĂ©es par la rĂ©munĂ©ration Ă  l’acte) de 7,9 %. En outre, le temps consacrĂ© par ces mĂ©decins Ă  la recherche (activitĂ© non rĂ©munĂ©rĂ©e par l’un ou l’autre des modes de rĂ©munĂ©ration) a diminuĂ© de 14,7 %. Enfin, le revenu des mĂ©decins qui sont passĂ©s Ă  la rĂ©munĂ©ration mixte s’est accru de 8,05 %, indiquant qu’il Ă©tait financiĂšrement rentable pour ceux-ci de choisir ce mode de rĂ©munĂ©ration.physician payment mechanisms, multitasking, mixed-payment systems, incentive contracts, labour supply, self-selection, panel estimation., mĂ©canismes de rĂ©munĂ©ration des mĂ©decins, fonctionnement multitĂąche, rĂ©munĂ©ration mixte, contrats incitatifs, offre de travail, auto-sĂ©lection, estimation en panel
