In a continuous time model with stochastic demand, two firms compete in R&D, with the lead patent affecting the probability of success of a second innovation competing in the same product market; the size and direction of this effect characterize the level of appropriability. From this...

The quality of teaching and learning today is still a distant dream, even when compared to the access to education. The last decade has seen an outbreak of some kind; in educational technologies, again a much debated topic but poorly substantiated. This paper synthesises facts and trends from...

The Bali Roadmap marks a milestone in the process of international consensus building, setting forth a multilateral legal framework to address climate change. Delegates at the UN Climate Change Conference in Bali (Dec. 3-15 2007) launched a two-year process with a comprehensive agenda and 2009...

This paper investigates how different damage rules in patent infringement cases shape competition when intellectual property rights are probabilistic. I develop a simple model of oligopolistic competition to compare two main liability doctrines that have been used in the US to assess...

Most patent pools are formed in the shadow of patent litigation as an attempt to settle disputes in regard to conflicting infringement claims and the validity of patents. To reflect this reality, I develop a simple framework to analyze the incentives to form a patent pool or engage in...

We investigate the stability of cooperative relationships between inventors and consequences for the characteristics and patent productivity of the respective regional innovation systems (RIS). The empirical analysis is for nine German regions over a period of 15 years. We find a rather high...

The development of inventor networks is characterized by the addition of a significant number of new inventors, while a considerable number of incumbent inventors discontinue. We estimate the persistence of knowledge in regional inventor networks using alternative assumptions about knowledge...
