The last decade has seen a growing interest among economists on the effect of diversity on the provision of social goods and the stock of social capital. Indeed, in the workplace, cooperation, trust, and other social goods may be important elements of the smooth functioning of an office, but...

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...

We conduct a field experiment where we vary both the presence of a gift exchange wage and the effect of the worker's effort on the manager's payoff. The results indicate a strong complementarity between the initial wage gift and the agent's ability to "repay the gift". We collect information on...

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...

In a tedious real effort task, subjects know that their piece rate is either low or ten times higher. When subjects are informed about their piece rate realization, they adapt their performance. One third of subjects nevertheless forego this instrumental information when given the choice - and...

In theory, the publication of performance ratings may improve performance through reputation concerns and peer effects or impede performance by demoralizing employees. This paper uses school-district data and a regression discontinuity design to answer how consumers and employees respond to...

Collective contests are examined permitting heterogeneity of stakes within every competing group. Our first concern is whether unequal distribution of stakes in a group can enhance its win probability. Our second concern is whether a large stake in a group can be individually disadvantageous. We...

A well-recognized problem in the multitasking literature is that workers might substantially reduce their effort on tasks that produce unobservable outputs as they seek the salient rewards to observable outputs. Since the theory related to multitasking is decades ahead of the empirical evidence,...

We analyze relational contracts for a set of agents when either (a) only aggregate output or (b) individual outputs are observable. A team incentive scheme, where each agent is paid a bonus for aggregate output above a threshold, is optimal in case (a). The team's efficiency may increase...

Does temperature affect economic performance? Has temperature always affected social welfare through its impact on physical and cognitive function? While many studies have explored the indirect links between climate and welfare (e.g. agricultural yield, violent conflict, or sea-level rise), few...
