Abstract

(english) Using first-hand data from the 2009 Employment and Informal Sector Survey (EESIC) in the two largest cities of the Republic of Congo, Brazzaville and Pointe-Noire, we analyse the impact of education on labour market outcomes, and identify the segments where education pays off the most. Multivariate analyses of the risk of unemployment and sectoral choice indicate that young people face serious difficulties in the labour market: for most of them, their only choice is to remain unemployed or to join the informal sector. To measure the specific impact of schooling on earnings, we address issues related to sample selection and endogeneity of education in the earnings function. The results shed light on heterogeneity in the returns to schooling across the two main cities and institutional sectors. An important finding is that the informal sector does not systematically lag behind the formal sectors in terms of returns to education. We emphasize convex returns to education, meaning that the last years in secondary and tertiary schooling yield the highest returns, while those of primary education are generally lower. This convexity is also apparent in the informal sector, where education (albeit on another scale) again appears as an important determinant of earnings. _________________________________ (français) En utilisant les données « Enquête sur l'Emploi et le Secteur Informel au Congo 2009 » (EESIC) portant sur les deux grandes villes de la République du Congo, Brazzaville et Pointe-Noire, nous analysons l’effet de l'éducation sur l’insertion sur le marché du travail, et identifions les segments où l'éducation procure les rendements privés les plus élevés. Nos analyses multivariées du risque de chômage et du choix sectoriel indiquent que les jeunes sont confrontés à de sérieuses difficultés : pour la plupart d'entre eux, l’alternative est entre une situation de chômage ou une insertion dans le secteur informel. Pour mesurer l'impact spécifique de la scolarité sur les gains individuels, nous abordons les questions liées à la sélection et à l’endogénéité de la variable d’éducation dans la fonction de gains. Les résultats mettent en évidence une hétérogénéité des rendements de l’éducation dans les deux villes et leurs secteurs institutionnels. Un résultat important est que le secteur informel ne se situe pas systématiquement derrière les secteurs formels (privé et public) en termes de rendements de l'éducation. Nous montrons l’existence de rendements convexes de l'éducation. Cette convexité est également apparente dans le secteur informel, là où l'éducation (quoique à une autre échelle) apparaît aussi comme un déterminant important des gains.
