There is evidence from the literature that firms enjoy higher productivity levels when the workforce employed is culturally more diverse. It is an open question whether this gain is utilized to shift the supply curve and set lower prices, in order to achieve a higher demand and possibly higher revenues. This knowledge gap is not addressed in the existing literature, and forms the departure of our research. We introduce a reduced-form model, inspired by the study of Melitz and Ottaviano (2008) on heterogeneous firms, and add labor productivity by using the approach of Ottaviano and Peri (2005) on cultural diversity. In our empirical study, we employ German data, while the field of research is conducted for single plants, and industry-specific effects are taken into account. Our analysis shows significant positive effects of the cultural diversity of the high-skilled workforce on the market size of single establishments. We conclude that emerging productivity gains are not just paid as dividend or factor rewards but are also used to set lower prices in order to achieve higher demand.
