Iran has the world's only government-regulated kidney market. We report the results of the first field study of donor behaviour in this unusual market. Participants have lower risk tolerance and higher patience levels than the Iranian average but display no difference in rationality from...

We provide experimental evidence on the effects of social disapproval by peers among communities of Uruguayan small-scale fishers exploiting a common pool resource (CPR). We combined this treatment with an in-group (groups from a single community) / mixed group (groups composed of fishers from...

Most evidence of hyperbolic discounting is based on violations of either stationarity or time consistency as observed in choice experiments. These choice reversals may however also result from time-varying discount rates. Hyperbolic discounting is a plausible explanation for choice reversals...

We present experimental evidence from a bilingual city in Northern Italy on whether the language spoken by a partner in a prisoner's dilemma game affects behavior and leads to discrimination. Running a framed field experiment with 828 six- to eleven-year old primary school children in the city...

Recent experimental research has examined whether contributions to public goods can be traced back to intuitive or deliberative decision-making, using response times in public good games in order to identify the specific decision process at work. In light of conflicting results, this paper...

This paper examines the empirical question of whether subjects' static choices among rewards received at different times are influenced by their expected income levels at those times. Moreover, we recover time preferences after compensating for possible income effects. Besides eliciting...

Does students' hand tremble after marking three consecutive identical answers in a multiple choice test? We design an experiment to study if the likelihood to change incorrectly to a different answer than the last one depends on the number of identical previous answers. We do not find a clear...

The conflict between pro-self and pro-social behaviour is at the core of many key problems of our time, as, for example, the reduction of air pollution and the redistribution of scarce resources. For the well-being of our societies, it is thus crucial to find mechanisms to promote pro-social...

What was once broadly viewed as an impossibility – learning from experimental data in economics – has now become commonplace. Governmental bodies, think tanks, and corporations around the world employ teams of experimental researchers to answer their most pressing questions. For their part,...

What happens when the tax authority increases enforcement in one tax with the level of compliance in other taxes? The very little evidence available is not conclusive. This paper presents a very simple analytical model that shows the conditions under which spillovers could be positive or...
