We analyze the characteristics of new businesses in the German ICT industry, distinguishing them based on their choice between two IPR regimes: open source software (OSS) or closed source software (CSS). The share of new firms with an OSS-based business model has increased considerably over the...

Demographic change will be one of the major challenges for economic policy in the developed world in the next decades. In this article, we analyze the relationship between age structure and the number of startups. We argue that an individual's decision to start a business is determined by his or...

This paper takes a different perspective toward the escape entry incentive of incumbent firms to innovate. New entrants spawned from incumbents are not necessarily a threat; they can complement incumbents' production by commercializing knowledge incumbents are not willing or able to exploit....

This paper constructs a Global Entrepreneurship Index (GEINDEX) that captures the contextual feature of entrepreneurship across countries. We find the relationship between entrepreneurship and economic development to be mildly S-shaped not U-shaped or L-shaped. Our findings suggest moving away...

A new model of economic growth introduces the knowledge filter between new generic knowledge and economically-useful knowledge. It identifies both the formation of new ventures and the absorptive capacity of incumbent firms as the mechanisms that penetrate the knowledge filter. Recent empirical...

We develop a model in which stronger protection of intellectual property rights has an inverted U-shaped effect on innovation. Intellectual property rights protection allows the incumbent firms to capture part of the rents of commercial exploration that would otherwise accrue to the...

In this study, we quantify the role of foreign-born founders in high-tech entrepreneurship in a nationally representative sample of rapidly growing high-impact companies. This class of companies drives job creation and aggregate growth in the U.S. We find that, while most previous studies have...

Cooperation can benefit and hurt firms at the same time. An important question then is: when is it better to cooperate. And how can an appropriate partner be selected? In this paper we present a model of inter-firm cooperation driven by cognitive distance, appropriability conditions and external...

Does exporting intermediate goods induce learning from importers? In this paper, we examine to what extent learning from German industries can be explained by knowledge spillovers, channeled through the export of intermediate goods. Our study is based on a sample of 27 German trade partners in...
