Entrepreneurship education ranks highly on policy agendas in Europe and the US, but little research is available to assess its impacts. In this context it is of primary importance to understand whether entrepreneurship education raises intentions to be entrepreneurial generally or whether it...

We investigate incidence and evolution of patent thickets. Our empirical analysis is based on a theoretical model of patenting in complex and discrete technologies. The model captures how competition for patent portfolios and complementarity of patents affect patenting incentives. We show that...

We examine empirically the role of lending relationships in determining the collateral requirements, costs and availability of external funding. The data originates from a recently concluded survey of small- and medium-sized German firms. In our descriptive analysis, we explore the borrowing...

Advocates of apprenticeship programmes often argue as if it is simply a matter of historical accident that such investment by US firms has been hindered. This paper explores the structure of incentives underpinning the German system of apprenticeship training. First, we describe three...

In this paper we discuss determinants of firm survival and growth in Germany within its pre-1989 boundaries. We argue that the legal form adopted by a firm is an important indicator of the riskiness of projects undertaken, and that firms under limited liability should be characterized by higher...

Using a newly constructed panel dataset of German enterprises, I estimate R&D and capital investment equations for the time period from 1990 to 1994. Simple accelerator specifications indicate considerable sensitivity of R&D and investment to cash flow for relatively small firms. Much of this...

We explore the tail of patented invention value distributions by using value estimates obtained directly from patent holders. The paper focuses on those full-term German patents of the application year 1977 which were held by West German and U.S. residents. The most valuable patents in our data...

Changing product quality poses a challenge for the computation of price indexes, in particular in technologically advanced industries. We assess the differences between traditional and quality-corrected indexes by computing hedonic and matched-model price indexes for personal computer database...

Through a survey, economic value estimates were obtained on 962 inventions made in the United States and Germany and on which German patent renewal fees were paid to full-term expiration in 1995. A search of subsequent U.S. and German patents yielded a count of citations to those patents....
