| Abstract: | We develop a model in which stronger protection of intellectual property rights has an inverted U-shaped effect on innovation. Intellectual property rights protection allows the incumbent firms to capture part of the rents of commercial exploration that would otherwise accrue to the entrepreneurs. Stronger patent protection will increase the incentive to do R+D and generate new knowledge. This has a positive impact on entrepreneurship and innovation. However, after some point, further strengthening patent protection will reduce the returns to entrepreneurship sufficiently to reduce overall economic growth. |

| Abstract: | We analyze a two-stage patent race. In the first phase firms seek to develop a research tool, an innovation that has no commercial value but is necessary to enter the second phase of the race. The firm that completes the second phase of the race first obtains a patent on the final innnovation and enjoys its profits. We ask whether patent protection for the innovator of the research tool is beneficial from the ex ante point of view. We show that there is a range of values of the final innovation such that firms prefer to have no Intellectual Property Rights for research tools. |

| Abstract: | The purpose of this paper is to investigate the pattern of knowledge flows as indicated by patent citations. In order to compute the technological proximity, we have followed the methodology developed by Jaffe (1986), where a technological vector is based on the distribution of patents of each firm across technology classes. As far as the geographic proximity is concerned, we have used the latitude and the longitude coordinates of the city in which each firm is located. The empirical results suggest that the effects of proximity variables on knowledge flows are rather differentiated. |

| Abstract: | Nanomaterials are seen as a key technology for the 21st Century, and much is expected of them in terms of innovation and economic growth. They could open the way to many radically new applications, which would form the basis of innovative products. In this context, it seems all the more important for regions to put their own innovation systems in place, and to ensure that they offer a suitable location for such activities in order to benefit from the expected growth. Many regions have already done so by establishing ‘science parks’ and ‘nanoclusters’. As nanomaterials are still in their infancy, both public research institutes and private businesses could play a vital role in the process. This paper investigates what conditions and configurations allow a regional innovation system to be competitive in a cutting-edge technology like nanomaterials. We analyse European Patent Office data at the German district level (NUTS-3) on applications for nanomaterial patents, in order to chart the effects of localised research and development (R&D) in the public and private sector. We estimate two negative binomial models in a knowledge production function framework and include a spatial filtering approach to adjust for spatial effects. Our results indicate that there is a significant positive effect of both public and private R&D on the production of nanomaterial patents. Moreover, we find a positive interaction between them which hints at the importance of their co-location for realising the full potential of an emerging technology like nanomaterials. |

| Abstract: | Over the past decades, there has been a dramatic increase in the foreign-ownership of firms in the four Nordic countries Denmark, Finland, Norway and Sweden. This increase has generated interest in the welfare effect of foreign take-over of national assets. In this paper we ask: how would a firm’s behaviour and performance have been if a foreign owner had not acquired the firm? The analysis is based on a sample of 5 186 firm-level observations in four Nordic countries, of which close to 30 percent are owned by foreign companies. Using an empirical approach that accounts for both selection bias and simultaneity bias, we establish some new findings regarding foreign ownership. First, no robust difference in the propensity to be innovative can be established. Second, among the group of innovative firms, foreign-owned multinationals are generally outperformed by domestic multinationals in R&D and innovation engagement. Third, despite the fact that domestic multinationals are considerably more involved in national innovation systems than other firms, they are not producing more innovation per R&D-dollar, controlling for firm size, human capital and industry. Finally, we find that foreign take-over of firms is neutral with respect to labour productivity, and hence that no evidence of welfare gain or welfare drain of foreign ownership can be established. |
