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.

This paper analyses the impact of the regional age structure on growth of German regions. Based on a neoclassical growth model an augmented Solow model was derived and estimated in a spatial econometric approach. Besides labor and human capital, public spendings and urbanisation measures are controlled for. Adding the age structure of the employed labor force, which we use as proxy for the age pattern of human capital, improves the regression model significantly. Spatial autocorrelation is controlled for and supports OLS results. To get deeper insights in the effectiveness of the age structure quantile regression techniques are applied to distinguish the effects between various levels of growth rates. The results of the different estimation approaches provide evidence that the age structure matters for growth.

We explore the impact of the age structure of human capital on average regional productivity by applying a spatial econometric analysis based on an augmented Lucas-type production function. We also apply a new definition of regional human capital focusing on its availability. The estimates provide evidence that there are age specific human capital effects in Germany and that a temporary increase in regional productivity could occur during the demographic transition. Furthermore, it becomes clear that the availability based definition of human capital provides additional insight and so, could enrich future studies on regional human capital.
