Does Labor Diversity affect Firm Productivity?

Using a matched employer-employee data-set, we analyze how workforce diversity in cultural background, education and demographic characteristics affects productivity of firms in Denmark. Implementing a structural estimation of the firms' production function (Ackerberg et al., 2006) we find that labor diversity in education significantly enhances a firm's value added. Hence, the negative effects, coming from communication and integration costs connected to a more culturally and demographically diverse workforce, seem to outweigh the positive effects coming from creativity and knowledge spillovers.
