Fast or Fair? A Study of Response Times

This paper uses a modified dictator game to investigate the relationship between response times and social preferences. We find that egoistic subjects make faster decisions than subjects with social preferences. Moreover, our within-analysis reveals that, for a given individual, egoistic payoff maximizing decisions are reached quicker than choices expressing social preferences.response times; social preferences

Luck or Cheating? A Field Experiment on Honesty with Children

We ran an experiment with children to study the development of honesty with age. We asked each child to toss a fair coin in private and to record the outcome (white or black) in a paper sheet. We rewarded only those who reported white. We found a fraction of reported whites signifi…cantly larger than 50%, uniformly across age groups. This suggests that some children cheat when cheating is profi…table and they are not observed. In a second treatment we told children not to cheat. This reminder reduced the probability of reporting white by 18% on average, and signifi…cantly more in girls.honesty; children; fi…eld experiment

Pay Dispersion and Work Performance

The effect of intra-firm pay dispersion on work performance is controversial and the empirical evidence is mixed. High pay dispersion may act as an extra incentive for employees' effort or it may reduce motivation and team cohesiveness. These effects can also coexist and the prevalence of one effect over the other may depend on the use of different definitions of what constitutes a "team." For this paper we collected a unique dataset from the men's major soccer league in Italy. For each match we computed the exact pay dispersion of each work team and estimated its effect on team performance. Our results show that when the work team is considered to consist of only the players who contribute to the result, high pay dispersion has a detrimental impact on team performance. Several robustness checks confirm this result. In addition, we show that enlarging the definition of work team causes this effect to disappear or even become positive. Finally, we find that the detrimental effect of pay dispersion is due to worst individual performance, rather than a reduction of team cooperation.Team productivity, Incentives, Pay dispersion.

Do not Trash the Incentive! Monetary incentives and waste sorting

This paper examines whether monetary incentives are an effective tool for increasing domestic waste sorting. We exploit the exogenous variation in the waste management policies experienced during the years 1999-2008 by the 95 municipalities in the district of Treviso (Italy). We estimate with a panel analysis that pay-as-you-throw (PAYT) incentive schemes increase by 12.3% the sorted-total waste ratio. This increase reflects a change in the behavior of households, who keep unaltered the production of total waste but sort it to a larger extent. Our data show that household behavior is also influenced by the policies of adjacent municipalities.Incentives, environment, waste management, PAYT

Temptation at work

To encourage worker productivity offices prohibit Internet use. Consequently, many employees delay Internet activity to the end of the workday. Recent work in social psychology, however, suggests that using willpower to delay gratification can negatively impact performance. We report data from an experiment where subjects in a Willpower Treatment are asked to resist the temptation to join others in watching a humorous video for 10 minutes. In relation to a baseline treatment that does not require willpower, we show that resisting this temptation detrimentally impacts economic productivity on a subsequent task.temptation, willpower, lab experiment.

Social Preferences and Strategic Uncertainty: An Experiment on Markets and Contracts

This paper reports experimental evidence on a stylized labor market. The experiment is designed as a sequence of three phases. In the rst two phases, P1 and P2; agents face simple games, which we use to estimate subjects social and reciprocity concerns, together with their beliefs. In the last phase, P3; four principals, who face four teams of two agents, compete by o¤ering agents a contract from a xed menu. Then, each agent selects one of the available contracts (i.e. he "chooses to work" for a principal). Production is determined by the outcome of a simple effort game induced by the chosen contract. We nd that (heterogeneous) social preferences are signi cant determinants of choices in all phases of the experiment. Since the available contracts display a trade-of between fairness and strategic uncertainty, we observe that the latter is a much stronger determinant of choices, for both principals and agents. Finally, we also see that social preferences explain, to a large extent, matching between principals and agents, since agents display a marked propensity to work for principals with similar social preferences

An experiment on markets and contracts : do social preferences determine corporate culture?

This paper reports experimental evidence on a stylized labor market. The experiment is designed as a sequence of three treatments. In the last treatment, TR3, four principals, who face four teams of two agents, compete by offering the agents a contract from a fixed menu. In this menu, each contract is the optimal solution of a (complete information) mechanism design problem where principals face agents’ who have social (i.e. interdependent) distributional preferences a’ la Fehr and Schmidt [19] with a specific parametrization. Each agent selects one of the available contracts offered by the principals (i.e. he “chooses to work” for a principal). Production is determined by the outcome of a simple effort game induced by the chosen contract. In the first two treatments, TR1 and TR2, we estimate individual social preference parameters and beliefs in the effort game, respectively. We find that social preferences are significant determinants of the matching process between labor supply and demand in the market stage, as well as principals’ and agents’ contract and effort decisions. In addition, we also see that social preferences explain the matching process in the labor market, as agents display a higher propensity to choose to work for a principal with similar distributional preferences.
