We draw some lessons from the Tunisian experience of social reforms and associated civil conflict. Our main interest is the riots that occurred after subsidy cuts and their possible substitution of price subsidies by direct cash transfers. We propose new welfare indicators apt to assess policy...

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...

The estimation of models of activity choice in LDCs (Less Developed Countries) is complicated by specific features of labour markets. In particular, entry into activity sectors is often restricted and worked hours are rationed. Moreover, in the informal sector workers may obtain their work...

In this paper, we study the return to human capital variables for wages of workers observed in Tunisian matched worker-firm data in 1999. We develop a new method based on multivariate analysis of firm characteristics, which allows us most of the benefits obtained by introducing firm dummies in...

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...

We conduct a case study of the linkages of task organization, human capital accumulation and wages in Morocco, using matched worker-firm data for Electrical-mechanical and Textile-clothing industries. In order to integrate task organization into the interacting processes of workers’ training...

We draw some lessons from the Tunisian experience of social reforms and associated unrest. Our main interest is the riots that occurred after subsidy cuts and the attempts at substitution of price subsidies by direct cash transfers. We propose new welfare indicators to assess reforms in such...
