We investigate a multi-period contest model in which a contestant.s present success gives an advantage over a rival in the future. How this win advantage affects contestants.efforts, and whether the laggard gives up or keep on fighting are key issues. We find that the expected effort of the...

We consider an effort-maximizing principal distributing a prize fund over two consecutive all-pay auctions. The two contestants are doubly heterogeneous: one of them has a head start in the fi rst contest; and winning contest one gives an advantage in contest two that varies between players. We...

The paper deals with rent-seeking behaviour among agents competing for future shares of a common renewable natural resource. Rent-seeking might become profitable when the agents expect that the distribution of the natural resource in future periods will be dependent on the agents' extraction of...

This paper analyses the endogenous formation of technology sharing coalitions with asymmetric firms. Coalition partners produce complementary technology advancements, although each firm determines its R&D investment level non-cooperatively and there is no co-operation in the product market. We...

This paper analyses endogenous formation of technology sharing coalitions with asymmetric firms. Coalition partners produce complementary technology advancements, although firms do not co-operate on R&D investment level or in the product market. The equilibrium coalition outcome is either...

In this paper we look at motivation over time by setting up a dynamic contest model where winning the first contest yields an advantage in the second contest. The win advantage introduces an asymmetry into the competition that we find reduces the expected value to the contestants of being in the...

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 and how...

We introduce learning by doing in a dynamic contest. Contestants compete in an early round and can use the experience gained to reduce effort cost in a subsequent contest. A contest designer can decide how much of the prize mass to distribute in the early contest and how much to leave for the...

We consider an industry where one firm with a superior technology competes for market shares with several rivals. The owner of the superior technology (the dominant firm) can license or transfer the source of its dominance to a subset of rivals. Allowing the non-license takers to remain active...
