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 endogeneity in conditional quantile models. We derive the asymptotic distribution of the …

This study aims at evaluating the actual profile of marginal productivity across the age groups within the workforce …. As age-productivity profile might differ between occupations, we differentiate the workforce simultaneously by skills … dataset for manufacturing, services and trade sectors. Labour productivity is found to be the lowest for the low-skilled older …
