Our study aims to measure the effects of spatial R&D spillovers on firms' patent production at the city level. We use an original method to estimate the spatial dimension of spillovers using count data. The method, based on a generalized cross entropy approach, allows us to test spatial...

This paper empirically analyzes the influence of road proximity on HIV- infection using geographical data on road infrastructure and the Demographic and Health Surveys collected in six African countries. Firstly we show that living in proximity to a major road increases the individual risk of...

Given the low condom use and high prevalence in some African countries, this paper addresses the question of whether these evidences are driven by a supply-side or a demandside issue. The role of road infrastructures on HIV/AIDS outcomes is investigated using data from the Demographic and Health...

In any fee for service system (FFS), doctors are incited to increase their activity such that outpatient care supply is strongly linked to private practice income. Thus, studying the private practice income determinants allows predicting doctors’ care provision. We aim first, to identify the...

We study the returns to human capital for workers observed in Tunisian matched worker-firm data in 1999. This tells us how these returns differ from those obtained in industrialised countries with matched data. We develop a new method based on multivariate analysis of firm characteristics, which...

Using matched employer-employee data collected in Mauritius and Madagascar in 2005, we add new evidence on the magnitude of the gender wage gap and on the relevance of the glass ceiling hypothesis recently observed in developed countries. We focus more closely on the role of firm characteristics...

In this article, we investigate the relevance of the glass ceiling hypothesis in France, according to which there exist larger gender wage gaps at the upper tail of the wage distribution. Using a matched worker-firm data set of about 1 30 000 employees and 14 000 employers, we estimate quantile...

According to the glass ceiling hypothesis evidenced in developed countries, there exist larger gender pay gaps at the upper tail of the wage distribution. In this paper, we investigate the relevance of a glass ceiling effect in Morocco using a matched worker-firm data set of more than 8000...

In spite of its predominant economic weight in developing countries, little is known about informal sector income dynamics vis-à-vis the formal sector. Some works have been done in this field using household surveys, but they only consider some emerging Latin American countries (Argentina,...

In any fee-for-service system, doctors may be encouraged to increase the number of services (private activity) they provide to receive a higher income. Studying private activity determinants helps to predict doctors’ provision of care. In the context of strong feminization and heterogeneity in...
