Despite its importance, the impact of vertical organization on innovation incentives has not been investigated in depth. This paper develops a number of testable hypotheses and then provides a first exploratory empirical analysis, using cross-sectional industry-level data. Two simple stylized...

The paper develops an oligopoly model of innovation and applies it to data from the Mannheim Innovation Panel. The model circumvents the need for market share and price elasticity data which typically can only be determined with measurement error and are therefore a major source of...

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...

This paper studies the effect of R&D spillovers on R&D spending and productivity in a sample of German manufacturing firms. Using panel estimation techniques, the results suggest that spillovers affect industries in a heterogeneous manner. In terms of R&D investment, firms in high-technology...

Financing constraints have been discussed as a major obstacle to innovation. Small and medium-sized enterprises and start-ups are particularly concerned by such impediments. Venture capital has emerged as a partial solution in some countries, but is only available for start-up firms with major...

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...
