Patent holders may choose to protect innovations with single patents or to develop portfolios of multiple, related inventions. We propose a simple decision-making model in which patent-holders may allocate resources to either expanding the number of related patents or investing in higher value...

We analyse the determinants of opposition to biotechnology and pharmaceutical patents granted by the European Patent Office between 1978–96. Opposition can be considered an early form of patent validity challenge suit. In our sample, 8.6% of the patents are attacked in opposition proceedings....

If redistribution is distortionary, and if the income of skilled workers is due to knowledge-intensive activities and depends positively on intellectual property, a social planner which cares about income distribution may in principle want to use a reduction in Intellectual Property Rights...

Using a repeated game approach, this paper models a North-South trade agreement under which North offers South improved market access (via a tariff reduction) if South agrees to prevent local imitation by strengthening its protection of intellectual property rights (IPRs). We show that such an...

This Paper is concerned with the interaction between trade policies and the protection of Intellectual Property Rights (IPRs). In particular, it investigates, within the framework of a general equilibrium model with endogenous growth, the welfare implications of an international agreement on one...

We address the problem faced by innovators who have an idea for a marketable product but must hire employees to bring the product to the market. Information leakage implies that newly-hired employees become informed of the idea and may attempt to bring the product to the market themselves. We...

This paper employs data from an extensive European survey to produce one of the first systematic assessments of the private economic value of patents. The estimated mean of our patent value distribution is higher than 3 million Euros, the median is about one-tenth, and the mode is around a few...

We develop a North-South model of reciprocal antidumping (AD). We find that AD wars are winnable for the Northern firm if the Southern market is sufficiently small relative to the North’s. The South can avert AD war with the North by expanding the home market size. It may however trigger AD...

Using a unique firm-level dataset this study shows that, contrary to the hopes of transition economies, foreign investors in the region are characterized by low, rather than high, R&D intensity. The results also indicate that investors with higher R&D spending are more likely to engage in...

This paper investigates how the mode of entry into a foreign market can be influenced by the intensity of R&D in an industry and the protection of intellectual property rights (IPR) in a recipient country. It then analyzes the link between the IPR regime and policies that place limits on the...
