We examine a Stackelberg game where a financially constrainedleader faces competition from a ‘deep pocket’ follower. We …

-tournament R&D competition. We consider thatsuccess in R&D is uncertain. We show that whether firms invest more under … Cournotcompetition or Bertrand competition is ambiguous and depends on the probability ofsuccess in R&D but does not depend on the degree … of product differentiation. While‘static’ welfare is higher under Bertrand competition, we find that ‘dynamic’ welfare …

Noncooperative games in which each player’s payo¤ function depends on anadditively separable function of every player’s choice variable may be transformedinto an aggregative game, which may be analysed using the conceptof ‘share functions’. The resulting approach avoids the...

We investigate the Nash equilibria of asymmetric, winner-take-all, imperfectlydiscriminating contests, focussing on existence, uniqueness and rentdissipation. When the contest success function is determined by a productionfunction with decreasing returns for each contestant, equilibria...

The rent-seeking model of Tullock (1980) has stimulated a large literature on rent-seekingcontests, of which Hillman (1989) and Nitzan (1994) provide useful surveys. AlthoughTullock's 'winner take all' model has been adapted and extended in numerous ways, thereremain fundamental modeling issues,...

We suggest an alternative way of analyzing the canonical Bergstrom-Blume-Varian model of non-cooperative voluntary contributions to a public goodthat avoids the proliferation of dimensions as the number of players is in-creased. We exploit this approach to analyze models in which the...

We study aggregative games in which players’ strategy sets areconvex intervals of the real line and (not necessarily differentiable)payoffs depend only on a player’s own strategy and the sum of allplayers’ strategies. We give sufficient conditions on each player’s payofffunction to...

The paper compares two models of evolution in symmetric twoplayergames with incomplete information. One model postulates thatthe type of a player is fixed, and evolution works within types. Inthe other model type-contingent strategies evolve. In the case of twotypes and two strategies it is...

The paper shows that there is a close connection between (constant)consistent conjectures in a given game and evolutionary stabilityof conjectures. Evolutionarily stable conjectures are consistent andconsistent conjectures are the only interior candidates for evolutionarystability...
