I analyse how patent litigation outcome in Germany affects the performance of the disputing firms by interpreting changes in a firm's credit rating as a proxy for changes in firm performance. The results match theoretical considerations on the functioning of the bifurcated German patent...

Real options investment theory predicts current investment falls as uncertainty about market returns increases. In the case of R&D investment, which is usually considered an irreversible form of investment, this effect should be quite pronounced. This paper tests the real options prediction...

Theoretical considerations suggest that secrecy reduces spillovers almost completely through non-disclosure, while the disclosure requirement of patents generates some spillover and at the same time allows firms to appropriate knowledge. In this paper we empirically analyze whether protection by...

The real options investment theory shows that greater uncertainty about market revenues reduces current R&D investment by increasing the value of waiting. This paper presents empirical evidence that patent protection mitigates the effect market uncertainty on R&D investment.

Innovators seek to protect their intellectual assets by patenting them, at the same time trying to avoid any disclosure of critical knowledge. Given that a patent specification has to include a clear description of the patented matter so that anybody "skilled in the art" is enabled to reproduce...

Classical patent literature assumes that patents grant well-defined legal rights to exclude others from practicing an invention. In this scenario, start-up companies benefit from the exclusive right to commercialize patent-protected inventions and the certification effect of patents which...

This paper follows up recent work on the relationship between (un-)employment and wage effects of social security financing undertaken by the OECD Jobs Study. Based on a simple macroeconometric model of the labour market, I investigate whether the peculiar OECD results for Germany on the...

In this paper the outlier robust GMM panel data estimator recently proposed by Lucas, van Dijk, and Kloek (1994) is applied to an Euler equation model of firm investment behaviour with imperfectly competitive product markets for a small panel of German nonfinancial stock companies. Plots for...

The surge in interfirm cooperative agreements can be seen as expressing a way for firms to respond to and to organize market failure, especially in technology markets. The incentives of firms to internalize activities are to avoid the disadvantages, or capitalize on the advantages, of...
