According to the well-known “merger paradoxâ€, in a Cournot market game mergers are generally unprofitable unless most firms merge. The present paper proposes an optimal merger mechanism. With this mechanism mergers are never unprofitable, more profitable than in other known mechanism,...

Tournaments have been objected as resulting from ad hoc restrictions to the contracting problem which are not easily justified. Taking into account that a performance measure might not be verifiable to a third party, however, a restriction to payments which sum up to a constant may be...

We analyze the duration of the patent examination process at the European Patent Office (EPO). Our data contain information related to the patent’s economic and technical relevance, EPO capacity and workload as well as novel citation measures which are derived from the EPO’s search...

We introduce a concept of emotions that emerge when workers compare their own performance with the performances of co-workers. Assuming heterogeneity among the workers the interplay of emotions and incentives is analyzed within the framework of rank-order tournaments which are frequently used in...

This paper derives conditions under which reputation enables certifiers to resist capture. These conditions alone have strong implications for the industrial organization of certification markets: 1) Honest certification requires high prices that may even exceed the static monopoly price. 2)...

Several empirical studies have challenged tournament theory by pointing out that (1) there is considerable pay variation within hierarchy levels, (2) promotion premiums only in part explain hierarchical wage differences and (3) external recruitment is observable on nearly any hierarchy level. We...

Where product innovation requires several complementary patents, fragmented property rights can be a factor that limits firms’ willingness to invest in the development and commercialization of new products. This paper studies multiple simultaneous R&D contests for complementary patents...

At least two: the reputation of their brand and a reputation for being tough on imitators of this brand. Sustaining a brand requires both investment in its reputation amongst consumers and the defence of the brand against followers that infringe upon it. I study the defence of trade marks...

Does gender play a role in the context of team work? Our results based on a real-effort experiment suggest that performance depends on the composition of the team. We find that female and male performance differ most in mixed teams with revenue sharing between the team members, as men put in...

This paper investigates how patent applications and grants held by new ventures improve their ability to attract venture capital (VC) financing. We argue that investors are faced with considerable uncertainty and therefore rely on patents as signals when trying to assess the prospects of...
