Cultural diversity and plant-level productivity [PDF]
Regional Science and Urban Economics, 2012 Abstract Using comprehensive data for German establishments, we estimate plant-level production functions to analyze if “cultural diversity” affects total factor productivity. We distinguish diversity in the establishment's workforce (the micro level) and in the aggregate labor force of the region where the plant is located (the macro level). We find

Labor diversity and firm productivity
European Economic Review, 2014 Using a matched employer–employee data-set, we analyze how workforce diversity associates with the productivity of firms in Denmark, following two main econometric routes. In the first one, we estimate a standard Cobb–Douglas function, calculate the implied total factor productivity and relate the latter to diversity statistics in a second stage.
