This brief note describes the step-by-step protocol for conducting online economics experiments at the UCSC LEEPS Laboratory. This protocol assumes that the subject pool is managed using ORSEE (Greiner, 2015) and the experiment backend and interfaces are developed and deployed using oTree (Chen,...

We apply gradient dynamics to population games with continuous action spaces. The application features Veblen-esque consumers whose preferences include a rank dependent component. The spontaneous formation and disappearance of shock waves is a central feature caused by the nonlinearity of the...

A preference for negative reciprocity is an important part of the human emotional repertoire. We model its role in sustaining cooperative behavior but highlight an intrinsic free-rider problem: the fitness benefits of negative reciprocity are dispersed throughout the entire group, but the...

A growing body of evidence suggests that assets included in market indexes such as the S&P 500 trade at a premium relative to other assets.
