Since a man’s reproductive success depends on his ability to outcompete other men, male competitiveness may be expected to have been exposed to strong selective pressure throughout human history. Accordingly, the relatively low level of physical violence observed between men has been viewed as a...

This paper studies the role of risk attitudes in determining the optimality of winner-take-all contests. We compare the typical singlewinner lottery contest with two alternatives, both spreading the rewards to more players: through holding multiple prize-giving lottery competitions or through...

Procuring an innovation involves motivating a research effort to generate a new idea and then implementing that idea efficiently. If research efforts are unveriable and implementation costs are private information, a trade-off arises between the two objectives. The optimal mechanism resolves the...

In the paper, we introduce and analyze a new methodology to estimate the volatility functions of jump diffusion models. Our methodology relies on the standard kernel estimation technique using truncated bipower increments. The relevant asymptotics are fully developed, which allow for the time span...

We study identification of the players’ preferences in a network formation game featuring complete information, nonreciprocal links, and a spillover effect. We decompose the network formation game into local games such that the network formation game is in equilibrium if and only if each local game...

Farsighted economic agents can use their advantage to exploit their more myopic counterparts. In public goods games played on networks, such an agent will attempt to manipulate as many of his neighbors as possible to contribute to the public good. We study the exploitation of a myopic population by...

In post-industrial settings, apolipoprotein E4 (APOE4) is associated with increased cardiovascular and neurological disease risk. However, the majority of human evolutionary history occurred in environments with higher pathogenic diversity and low cardiovascular risk. We hypothesize that in high-...
