Self-selection Into Contests∗
We study self-selection into contests among a large population of heterogeneous agents. We show that entry into the “richer” contest (in terms of show-up fees, number or value of prizes) is non-monotone in ability. Entry into the more meritocratic (i.e., discriminatory) contest exhibits two interior extrema. Other testable predictions of our model are: 1) All else equal, the more meritocratic c...

15 صفحه اولPreemptive defensive self-sacrifice by ant workers.
Worker insects altruistically sacrifice their own reproduction to rear nondescendant kin. This sacrifice reaches its most spectacular level in suicidal colony defense. Suicidal defense, such as when the sting of a honeybee worker embeds in a predator and then breaks off, is normally a facultative response. Here we describe the first example of preemptive self-sacrifice in nest defense. In the B...
