We derive a necessary and sufficient condition for the existence of equilibria with only two active players in the all-pay auction with complete information and identity-dependent externalities. This condition shows that the generic equilibrium of the standard all-pay auction is robust to the introduction of "small" identity-dependent externalities. In general, however, the presence of identity...

In connection with the problem of struc...

Plato and Aristotle both believe that contrariety is fundamental to the analysis of change. At Phaedo 70e4-71a10, for example, Socrates says that all things that have an origin ( χει γ νεσιν) and that have contraries ( ναντ αι) 1 come to be (γ γνεται) from ( κ) contraries.
