Are humans intuitively cooperative, or do we need to deliberate in order to be generous to others? The Social Heuristics Hypothesis (SHH) proposes that fast instinctive decision making promotes cooperation in social dilemmas. In this paper, we conduct a novel time-pressure experiment to shed...

We study the role of heuristic versus deliberative processing in intertemporal choice. Using studies in the Democratic Republic of Congo and an online labor market, we show that waiting periods - designed to prompt deliberation by temporally separating news about choice sets from choices...

In this paper, we analyze the role of intuitive versus deliberative thinking in stag hunt games. To do so we, first, provide a conceptual framework predicting that, under the assumption that stag is the ruling social convention in real life interactions, players who make their choices fast and...

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...

Peer effects arise in situations where workers observe each others' work activity. In this paper we disentangle the effect of observing a peer from that of being observed by a peer, by setting up a real effort experiment in which we manipulate the observability of performance. In particular, we...

We present results from a field experiment designed to measure the importance of managerial commitment to a contract within a firm that pays its workers piece rates. In the tree planting industry the piece rate paid to workers is determined as a function of the difficulty of the terrain to be...

We conduct a field experiment in a controlled work environment to investigate the effect of motivational talk and its interaction with monetary incentives. We find that motivational talk significantly improves performance only if it is accompanied by performance pay. Moreover, performance pay...

Contributing to a social cause can be an important driver for workers in the public and non-profit sector as well as in firms that engage in Corporate Philanthropy or other Corporate Social Responsibility policies. This paper compares the effectiveness of social incentives - that take the form...

Most large-scale economic experiments use a between-subjects random incentive system-BRIS-which selects a subset of the participants at random and offers real payment only to the selected participants. We evaluate the relative impact of nominal payoffs and the selection probability on the...
