In recent years, the banking industry has witnessed several cases of excessive risk-taking that frequently have been attributed to problematic professional norms. We conduct experiments with employees from several banks in which we manipulate the saliency of their professional identity and subsequently measure their risk aversion in a real stakes investment task. If bank employees are exposed to professional norms that favor risk-taking, they should become more willing to take risks when their professional identity is salient. We find, however, that subjects take significantly less risk, challenging the view that the professional norms generally increase bank employees’willingness to take risks.

Most previous studies on intertemporal labor supply found very small or insignificant substitution effects. It is possible that these results are due to constraints on workers' labor supply choices. We conducted a field experiment in a setting in which workers were free to choose hours worked and effort per hour. We document a large positive elasticity of overall labor supply and an even larger elasticity of hours, which implies that the elasticity of effort per hour is negative. We examine two candidate models to explain these findings: a modified neoclassical model with preference spillovers across periods, and a model with reference dependent, loss-averse preferences. With the help of a further experiment, we can show that only loss-averse individuals exhibit a negative effort response to the wage increase. (JEL J22, J31)

Casual evidence as well as daily experience suggest that many people have a strong aversion against being the 'sucker' in social dilemma situations. As a consequence, those who cooperate may be willing to punish free-riding, even if this is costly for them and even if they cannot expect future benefits from their punishment activities. A main purpose of this paper is to show experimentally that there is indeed a widespread willingness of the cooperators to punish the free-riders. Our results indicate that this holds true even if punishment is costly and does not provide any material benefits for the punisher. In addition, we provide evidence that free-riders are punished the more heavily the more they deviate from the cooperation levels of the cooperators. Potential free-riders, therefore, can avoid or at least reduce punishment by increasing their cooperation levels. This, in turn, suggests that in the presence of punishment opportunities there will be less free riding. Testing this conjecture is the other major aim of our paper.

We review the vast literature on social preferences by assessing what is known about their fundamental properties, their distribution in the broader population, and their consequences for important economic and political behaviors. We provide, in particular, an overview of the empirical characteristics of distributional preferences and how they are affected by merit, luck, and concerns for equality of opportunity. In addition, we discuss the evidence for reciprocity and guilt aversion and assess the empirical relevance of self-image and social image concerns in prosocial behaviors. The overall evidence indicates that a large majority of individuals have some sort of social preferences, while purely self-interested subjects are a minority. We also document converging insights from the lab and the field on the impact of wage inequality on work morale, employees’ resistance to wage cuts, and the role of social preferences for cooperation and collective action, distributive politics, and individuals’ selection into different occupations.

In a wide variety of settings, spiteful preferences would constitute an obstacle to cooperation, trade, and thus economic development. This paper shows that spiteful preferences - the desire to reduce another's material payoff for the mere purpose of increasing one's relative payoff - are surprisingly widespread in experiments conducted in one of the least developed regions in India (Uttar Pradesh). In a one-shot trust game, the authors find that a large majority of subjects punish cooperative behavior although such punishment clearly increases inequality and decreases the payoffs of both subjects. In experiments to study coordination and to measure social preferences, the findings reveal empirical patterns suggesting that the willingness to reduce another's material payoff - either for the sake of achieving more equality or for the sake of being ahead - is stronger among individuals belonging to high castes than among those belonging to low castes. Because extreme social hierarchies are typically accompanied by a culture that stresses status-seeking, it is plausible that the observed social preference patterns are at least partly shaped by this culture. Thus, an exciting question for future research is the extent to which different institutions and cultures produce preferences that are conducive or detrimental to economic development.

When choice is stochastic, revealed preference analysis often relies on random utility models. However, it is impossible to infer preferences without assumptions on the distribution of utility noise. We show that this difficulty can be overcome by using response time data. A simple condition on response time distributions ensures that choices reveal preferences without distributional assumptions. Standard models from economics and psychology generate data fulfilling this condition. Sharper results are obtained under symmetric or Fechnerian noise, where response times allow uncovering preferences or predicting choice probabilities out of sample. Application of our tools is simple and generates remarkable prediction accuracy.
