In this paper, we develop a test to detect the presence of endogeneity in conditional quantiles. Our test is a Hausman-type test based on the distance between two estimators, of which one is consistent only under no endogeneity while the other is consistent regardless of the presence of...

In this paper, we propose a variance reduction method for quantile regressions with endogeneity problems. First, we derive the asymptotic distribution of two-stage quantile estimators based on the fitted-value approach under very general conditions on both error terms and exogenous variables....

In this paper, we test and reject the separability of production and consumption decisions of agricultural households in Ethiopia, using data from a rural household survey conducted in 1994 and an estimated labour demand equation. We also elicit socio-demographic and asset variables that are...

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 and...

We study the impact of violent conflict on social capital, as measured by citizen participation in community groups, defined by four activity types: governance, social service, infrastructure development and risk-sharing. Combining household panel data from Indonesia with conflict event...

In this paper, we conduct an econometric analysis of the links of on-the-job training (OJT) and worker remuneration in the area of Tunis using a case study data based on eight firms. We pay particular attention to the way the OJT cost may be shared between firms and workers. This is done through...
