In this paper, we study the return to human capital variables for wages of workers observed in Tunisian matched worker-firm data in 1999. This tells us how returns to human capital in a Less Developed Country like Tunisia differ from the industrial countries usually studied with matched data. We...

(english) We study the relationship between wages, human capital accumulation and work organisation in Morocco using matched worker-firm data for Metallurgical-electrical and Textile-clothing firms. While wages are found to rise with all human capital characteristics, returns to education and...

(français) Nous analysons les rendements du capital humain à partir de données liées employeurs-employés collectées en Tunisie en 1999 et indiquons comment ces rendements diffèrent de ceux généralement obtenus dans les pays industrialisés avec ce type de données. Nous développons une...

From Tunisian matched worker-firm data in 1999, we study the returns to human capital in two leading manufacturing sectors. Workers in the IMMEE benefit from higher returns to human capital than their counterparts in the Textile-clothing industry. In the IMMEE firms, low wage workers experience...

This case study exploits matched firm-employee Tunisian data in order to underline the role played by within-firm human capital in worker remuneration. The estimated returns to human capital in wage equations remain unchanged when the dummies representing firm heterogeneity are replaced in the...

We present the asymptotic properties of double-stage quantile regression estimators with random regressors, where the first stage is based on quantile regressions with the same quantile as in the second stage, which ensures robustness of the estimation procedure. We derive invariance properties...

In general models, the strong quasi-concavity of the objective function, sufficient for theoretical properties of demands in consumer theory, is often arbitrary. Then, weaker global concavity conditions that preserve such properties are desirable for such models. We propose a new global...

(english) The purpose of this paper is to study the effects of education on urban labour market participation and earnings in seven major West African cities. Our results show that although education does not always guard against unemployment, it does increase individual earnings in Abidjan,...
