El esfuerzo en el trabajo de los docentes: el impacto del experimento AGEMAD
2014
International audience; Utilizando datos de un experimento randomizado realizado en Madagascar durante dos años escolares completos, se evalúan las heterogeneidades de impacto de unas intervenciones específicamente diseñadas para mejorar la gestión del proceso pedagógico en la escuelas primarias. Nuestros resultados muestran que intervenciones intensivas y directas a lo largo de la jerarquía educativa permiten cambiar el comportamiento de los docentes de manera significativa. Sin embargo, el impacto medio del programa oculta una gran heterogeneidad. Los maestros que tenían pocos alumnos así como los que tenían unas buenas condiciones de trabajo se beneficiaron más de las mismas. Por el cont…

L'estimation de modèles à variable dépendante dichotomique
1977
Document de travail de l'IME, n°20, avril 1977en ligne sur http://lara.inist.fr/bitstream/handle/2332/2144/IME_DT_77_20.pdf?sequence=1; e texte a pour objet l'étude de l'estimation de la probabilité de réalisation d'un évènement E, étant donné un certain nombre de caractéristiques associées à cette éventualité. Deux modèles sont envisagés, à savoir le modèle de régression linéaire et le modèle de régression logistique. Le premier, qui revient à estimer une fonction de probabilité linéaire ne vérifie plus les hypothèses classiques des moindres carrés ordinaires. Une première amélioration consiste alors à estimer le modèle par la méthode des moindres carrés généralisés. Cependant, outre le pr…

Productivity analysis of Latvian companies using ORBIS database
2021
International audience; This research study uses ORBIS microdata at the company level to analyse productivity of 167 thousand economically active Latvian companies over 2011-2018. The aim of the study is twofold-to find factors consistently associated with productivity at the company level; and to recommend possible criteria for companies to receive a state support (from the view of enhancing aggregate productivity in the long term). Our research results show that productivity of Latvian companies is positively related to their size, age, as well as location closer to Riga and other big cities. However, there is a substantial within-group variation in productivity between companies. Multiva…
Normalizing biproportional methods
2002
International audience; Biproportional methods are used to update matrices: the projection of a matrix Z to give it the column and row sums of another matrix is R Z S, where R and S are diagonal and secure the constraints of the problem (R and S have no signification at all because they are not identified). However, normalizing R or S generates important mathematical difficulties: it amounts to put constraints on Lagrange multipliers, non negativity (and so the existence of the solution) is not guaranteed at equilibrium or along the path to equilibrium.
Managerial Behavior in the Lab: Information Disclosure, Decision Process and Leadership Style
2019
This paper reports the results from a lab experiment in which subjects playing the manager role can implement either an efficient / inegalitarian allocation or an inefficient / egalitarian allocation of payoffs. The experiment simulates a stylized managerial context by allowing the manager to manipulate information and select the decision process and by allowing the stakeholders to retaliate against the manager given different choices in the decision process. We found that the inefficient allocation is often selected and that this choice depends on whether the employees can retaliate against the manager and on whether the manager can hide information about the payoffs. The social preference…
Job Satisfaction among Primary School Personnel
2016
International audience; This article analyzes the job satisfaction of primary school teachers inMadagascar. Based on the estimation of multilevel models, low wages and problems getting paid, job insecurity, lack of in-service training, high pupil-teacher ratios, and lack of basic infrastructure and teaching materials are identified as the main reasons for dissatisfaction. Principals' control of teachers' activities also adversely affects satisfaction, suggesting that, in Malagasy schools, neither school directors nor teachers have succeeded in adopting organizational cultures based on cooperation among their members. These results are likely to stimulate debates on educational policy, both …
Is there a Market Value for Energy Performance in a Local Private Housing Market ? An efficiency analysis approach
2018
This paper aims to find evidence of a “green value” in a local housing market using notarial data on a small urban area in France. We use frontier functions, an original approach that departs from customary hedonistic regressions, to model housing market prices as a production set bordered by an efficiency frontier estimated by Data Envelopment Analysis (DEA). The paper tests if difference in prices (i.e. the distance from the frontier) can be explained by energy performance measured as a normalized categorical ascending kWh/m²/year grade (or Energy Performance Certificate -EPC). We show that there is significative evidence for energy performance's market value. The “Green Property Value” i…
