We demonstrate that heat inhibits learning and that school air-conditioning mitigates this effect. Student fixed effects models using 10 million PSAT-retakers show hotter school days in years before the test reduce scores, with extreme heat being particularly damaging. Weekend and summer heat...

In this paper we present results from a large scale real effort experiment in an online labor market investigating the effect of performance pay and two common leadership techniques: Positive expectations and specific goals. We find that positive expectations have a significant negative effect...

Many organizations nowadays combine profits with a social mission. This paper reveals a new hidden benefit of the mission: its role in facilitating the emergence of efficiency wages. We show that in a standard gift-exchange principals highly underestimate agents' reciprocity and, thereby, offer...

I study how motivation shapes own and peers’ educational success. Using data from Project STAR, I find that academic motivation in early elementary school, as measured by a standardized psychological test, predicts contemporaneous and future test scores, high school GPA, and college-test...

We conducted a randomized controlled trial involving nearly 700 customer-service representatives (CSRs) in a Canadian government service agency to study whether providing CSRs with performance feedback with or without peer comparison affected their subsequent organ donor registration rates....

The effects of performance pay in routine, easy to measure tasks are well-documented, but they are much less understood in knowledge creation. This paper studies the effects of explicit and implicit, career concerns incentives common in knowledge work in a multitasking model, and estimates their...

Academics are increasingly expected to engage in public discussions. We study how engagement conditions affect academics’ engagement attitudes via a survey experiment among 4,091 tenured professors in Germany. Consistent with the crowding-out of intrinsic motivation, we find less-positive...

We study the relationship between outside options and workers’ motivation to exert effort. We evaluate changes in outside options arising from age and experience cutoffs in the Austrian unemployment insurance (UI) system, and use absenteeism as a proxy for worker effort. Results indicate that...

Empirical research suggests that - rather than improving incentives - exerting control can reduce workers' performance by eroding motivation. The present paper shows that intention-based reciprocity can cause such motivational crowding-out if individuals differ in their propensity for...

We develop a methodology to sign output distortions in the random participation framework. We apply our method to monopoly nonlinear pricing problem, to the regulatory monopoly problem and mainly to the optimal income tax problem. In the latter framework, individuals are heterogeneous across two...
