This study shows for a large sample of R&D-active manufacturing firms over the period 2000-2009 that knowledge alliances have a positive effect on patenting in terms of both quantity and quality. However, when distinguishing between alliances that aim at joint creation of new knowledge and...

We analyze the relationship between institutional investors, innovation and financing constraints. Building on the empirical framework of Aghion et al. (2013), we find that the effect of institutional ownership on innovation is concentrated in industries with high dependence on external finance...

This paper analyses the impact of common ownership on markups and innovation and adds to the discussion of the recently observed patterns of a long term rise in market power. We shed light on the inconclusiveness of results regarding the effects of common ownership on markups in the existing...

R&D collaboration facilitates pooling of complementary skills, learning from the partner as well as sharing risks and costs. Research therefore repeatedly stressed the positive relationship between collaborative R&D and innovation performance. Collaboration, however, involves transaction costs...

All consumers in the market are subscribed to one...

This paper explores the relationship between the intensity of competition in product markets and firms' incentives to lower their production costs by illegal means. Our framework combines a Salop circle with a crime model à la Becker, allowing us to differentiate between several measures for...

This paper experimentally studies the role of search cost in duopoly markets where sellers may be able to coordinate pricing decisions. We vary the level of search cost and whether sellers can communicate. While we find that consumers are more likely to invest in search when cost is reduced, we...
