Many experiments indicate that most individuals are not purely motivated by material self interest, but also care about the well being of others. In this paper we examine tournaments among inequity averse agents, who dislike disadvantageous inequity (envy) and advantageous inequity (compassion)....

The "ratchet effect" refers to a phenomenon where workers whose compensation is based on productivity strategically restrict their output, relative to their capability, because they rationally anticipate that high levels of output will be met with increased or "ratcheted-up" expectations in the...

Modeling the incentive effects of competitions among employees for promotions or financial rewards, economists have largely ignored the effects of competition on effort provision once the competition is finished. In a laboratory experiment, we examine how competition outcomes affect the...

Fixed-wage workers comprise the bulk of the labor force and yet little is known about how they respond to wage changes. Given recent interest in theories of reciprocity and intrinsic motivation and their implications for effort provision, the neoclassical prediction seems less obvious today. To...

This paper studies the effect of providing feedback to college students on their position in the grade distribution by using a randomized control experiment. This information was updated every six months during a three-year period. In the absence of treatment, students' underestimate their...
