| Abstract: | The value of social network analysis is critically dependent on the comprehensive and reliable identification of actors and their relationships. We compare regional knowledge networks based on different types of data sources, namely, co-patents, co-publications, and publicly subsidised collaborative Research and Development projects. Moreover, by combining these three data sources, we construct a multilayer network that provides a comprehensive picture of intraregional interactions. By comparing the networks based on the data sources, we address the problems of coverage and selection bias. We observe that using only one data source leads to a severe underestimation of regional knowledge interactions, especially those of private sector firms and independent researchers. The key role of universities that connect many regional actors is identified in all three types of data. |

| Abstract: | This paper analyzes in how far immigration affects firm formation at the regional level. For this purpose, we exploit a placement policy in Germany in the 1990s for immigrants of German origin from Eastern Europe and the former Soviet Union. Our panel regressions suggest that immigration had a positive impact on regional firm formation. The most likely mechanisms driving this result are labor supply-side effects and positive implications of cultural diversity. Overall, our paper demonstrates that immigration induced changes in local labor supply can partially be absorbed by the creation of firms. |

| Abstract: | How important is foreign knowledge for domestic innovation outcomes? How is this relation shaped by globalization and the attendant intensification of international competition? Our empirical approach extends the previous literature by analyzing a large panel comprising industries in both advanced and emerging economies over the past two decades. We find that barriers to the domestic diffusion of foreign knowledge have fallen significantly for emerging economies. For all countries, and especially for emerging economies, inflows of foreign knowledge have a growing and quantitatively important impact on domestic innovation. Controlling for the amount of domestic R&D, we find evidence that increases in international competitive pressure at the industry level had a positive effect on domestic innovation outcomes |
