✦ Synopsis


It is shown that there are at least two evolutionarily stable strategies, or ESSs, in the war of attrition with a role asymmetry when players make an error with a small but positive probability in implementing their strategy choices. This result proves Maynard Smith's original conjecture that players should choose asymmetric pure strategies in the asymmetric war of attrition. It is also in contrast to the standard non-existence result of an ESS in this game under complete information. To derive this result we discretize the original game and apply the limit ESS condition introduced by Selten. The result is also compared with other evolutionary analyses of this game.

We derive the ESS for the generalized asymmetric war of attrition, where payo!s to contestants may vary in time and may depend on some characteristic, called the &&role'' of an individual. We use the same approach as Hammerstein & Parker (1982), who examined an asymmetric war of attrition. We consid

Several modifications and generalisations of the basic model ( 1) have been investigated (e.g. Bishop and Cnnnings (1978), (1986), Haigh and Rose (1980), Maynard Smith andParker (1976)). Here we analyze several different models for the generalisation of (1) to n-person conflicts. The common feature

In the asymmetric war of attrition the two opponents each play a different role. But mistakes in assumption of role are possible. Hammerstein and Parker (1982, J. theor. Biol. 96, 647-682) investigated this game to calculate the ESS of the distribution of the cost (fight duration) the players should
