Summary. -This paper investigates the effects of a remedial education program-the Roma Teaching Assistant Program-targeting the socially excluded Roma minority in Serbia. By using first-hand collected data, we find evidence that children exposed to the program went more to school. We do not find an effect on dropouts or marks for all grades. An examination of heterogeneous effects suggests that children in the first grade benefited more from the program as compared to their older peers through lower dropouts and better marks. Overall, our results suggest that well-targeted remedial education programs can boost outcomes of low performers.

Purpose -There is plenty of individual-level evidence, based on the estimation of Mincerian equations, showing that better-educated individuals earn more. This is usually interpreted as a proof that education raises labour productivity. Some macroeconomists, analysing cross-country time series, also support the idea that the continuous expansion of education has contributed positively to growth. Surprisingly, most economists with an interest in human capital have neglected the level of the firm to study the education-productivity-wage nexus. And the few published works considering firm-level evidence are lacking a proper strategy to cope with the endogeneity problem inherent to the estimation production and wage functions. The purpose of this paper is to aim at providing estimates of the causal effect of education on productivity and wage labour costs. Design/methodology/approach -This paper taps into a rich, firm-level, Belgian panel database that contains information on productivity, labour cost and the workforce's educational attainment to deliver estimates of the causal effect of education on productivity and wage/labour costs. Therefore, it exclusively resorts to within firm changes to deal with time-invariant heterogeneity bias. What is more, it addresses the risk of simultaneity bias (endogeneity of firms' education-mix choices in the short run) using the structural approach suggested by , alongside more traditional system-GMM methods (Blundell and Bond, 1998) where lagged values of labour inputs are used as instruments.Findings -Results suggest that human capital, in particular larger shares of university-educated workers inside firms, translate into significantly higher firm-level labour productivity, and that labour costs are relatively well aligned on education-driven labour productivity differences. In other words, the authors find evidence that the Mincerian relationship between education and individual wages is driven by a strong positive link between education and firm-level productivity.

In this paper, we investigate the child penalty in Russia using data from the Russian Longitudinal Monitoring Survey (RLMS) and the methodological framework of event studies. We find that five years after childbirth, women suffer an earnings penalty, while no effect is observed for men. The mothers’ penalty stems exclusively from lower employment after childbirth. Contrary to similar studies on Western Europe and the US, we do not find penalties in terms of working hours or hourly wage rates for women who remain in the labour force. We further find that mothers’ employment penalty is strongly driven by household characteristics and by their spouses’ beliefs. Finally, we find that parenthood decreases the probability of working in supervisory positions for mothers and in the public sector for fathers.
