An active area of research within economics concerns the underpinnings of why people give to charitable causes. This study takes a new approach to this question by exploring motivations for giving among children aged 3–5. Using data gathered from 122 children, our artefactual field experiment...

We experimentally study overbidding in contests and find that overbidding is significantly higher when subjects are given a large per-experiment endowment rather than when the endowment is given per-period. Risk-aversion and non-monetary utility of winning can partially explain our findings.

We find the sufficient conditions for the existence of multiple equilibria in Tullock-type contests, and show that asymmetric equilibria arise even under symmetric prize and cost structures. We then present existing contests where multiple equilibria exist under reasonably weak conditions.
