Résumé : This article provides first microeconometric evidence on whether corporate social responsibility (CSR) influences the relationship between overeducation and labour productivity at the Belgian private firms level. We estimate a productivity equation and rely on detailed linked employer-employee panel data covering the period 1999-2010. By using the GMM estimator, our estimates first exhibit a positive and significant impact of over-education on labour productivity, supporting thereby human capital arguments. Next, they suggest that the effect of over-education is enhanced when firms implement CSR behaviour, i.e. when they hire workers: i) whose education levels match required levels and ii) are diverse in terms of gender and age. So our results suggest that CSR, besides representing an innovative and proactive approach for firms' stakeholders, may also improve working conditions and thereby the beneficial effet from overeducation on labour productivity within firms.
