Apparently judges’ decisions are not motivated by maximizing their own profit. The literature uses two strategies to explain this observation: judges care about the long-term monetary consequences for themselves, or individuals who are more strongly motivated by the common good self-select...

We introduce the "ball-catching task", a novel computerized real effort task, which combines "real" efforts with induced material cost of effort. The central feature of the ball-catching task is that it allows researchers to manipulate the cost of effort function as well as the production...

We investigate whether there is a link between conditional cooperation and betrayal aversion. We use a public goods game to classify subjects by type of contribution preference and by belief about the contributions of others; and we measure betrayal aversion for different categories of subject....

We investigate the impact of wage comparisons for worker productivity. We present three studies which all use three-person gift-exchange experiments. Consistent with Akerlof and Yellen's (1990) fair wage-effort hypothesis we find that disadvantageous wage discrimination leads to lower efforts...

We use survey and experimental data to explore how effort choices and preferences for redis-tribution are linked. Under standard preferences, redistribution would reduce effort. This is different with social preferences. Using data from the World Value Survey, we find that respondents with...

Building on a theoretical model we test the hypothesis that effort choices and preferences for redistribution are simultaneously determined. Using cross-country panel data from the World Value Survey, we find that it is important to model preferences for redistribution and effort choices...
