Psychological insights have made inroads within most major areas of study in economics. One area where less advance has been made is environmental and resource economics. In this study, we examine the implications of preference reversals over evaluation modes, in which stated economic values critically depend on whether the good is valued jointly with others or in isolation. The question arises because two commonly used methods for eliciting stated preferences differ in that one presents objects together and another presents objects to be evaluated in isolation. Beyond showing an example of the import of behavioral economics, our empirical evidence sheds new light on the factors associated with insensitivity of valuations to the scope of the good

The dictator game represents a workhorse within experimental economics, frequently used to test theory and to provide insights into the prevalence of social preferences. This study explores more closely the dictator game and the literature's preferred interpretation of its meaning by collecting data from nearly 200 dictators across treatments that varied the action set and the origin of endowment. The action set variation includes choices in which the dictator can "take" money from the other player. Empirical results question the received interpretation of dictator game giving: many fewer agents are willing to transfer money when the action set includes taking. Yet, a result that holds regardless of action set composition is that agents do not ubiquitously choose the most selfish outcome. The results have implications for theoretical models of social preferences, highlight that "institutions" matter a great deal, and point to useful avenues for future research using simple dictator games and relevant manipulations.

Randomization to treatment is fundamental to statistical control in the design of experiments. But randomization implies some uncertainty about treatment condition, and individuals differ in their preferences towards taking on risk. Since human subjects often volunteer for experiments, or are allowed to drop out of the experiment at any time if they want to, it is possible that the sample observed in an experiment might be biased because of the risk of randomization. On the other hand, the widespread use of a guaranteed show-up fee that is non-stochastic may generate sample selection biases of the opposite direction, encouraging more risk averse samples into experiments. We undertake a field experiment to directly test these hypotheses that risk attitudes play a role in sample selection. We follow standard procedures in the social sciences to recruit subjects to an experiment in which we measure their attitudes to risk. We exploit the fact that we know certain characteristics of the population sampled, adults in Denmark, allowing a statistical correction for sample selection bias using standard methods. We also utilize the fact that we have a complex sampling design to provide better estimates of the target population. Our results suggest that randomization bias is not a major empirical problem for field experiments of the kind we conducted if the objective is to identify marginal effects of sample characteristics. However, there is evidence that the use of show-up fees may have generated a sample that was more risk averse than would otherwise have been observed.

We combine the choice data of proposers and responders in the ultimatum game, their expectations elicited in the form of subjective probability questions, and the choice data of proposers (dictators) in a dictator game to estimate a structural model of decision making under uncertainty. We use a large and representative sample of subjects drawn from the Dutch population. Our results indicate that there is considerable heterogeneity in preferences for equity in the population. Changes in preferences have an important impact on decisions of dictators in the dictator game and responders in the ultimatum game, but a smaller impact on decisions of proposers in the ultimatum game, a result due to proposers subjective expectations about responders decisions. The model which uses subjective data on expectations has better predictive power and lower noise level than a model which assumes that players have rational expectations.

Second-price auctions are designed to induce people to reveal their private preferences for a good. Laboratory evidence suggests that while these auctions do a reasonable job on aggregate, they fall short at the individual level, especially for bidders who are off-margin of the market-clearing price. Herein we introduce and explore whether a random nth-price auction can engage all bidders to bid sincerely. Our results first show that the random nth-price auction can induce sincere bidding in theory and practice. We then compare the random nth-price to the second-price auction. We find that the second-price auction works better on-margin, and the random nth-price auction works better off-margin.

We experimentally investigate the effect of social identification and information feedback on individual behavior in contests. In all treatments we find significant over-expenditure of effort relative to the standard theoretical predictions. Identifying subjects through photo display decreases wasteful effort. Providing information feedback about others' effort does not affect the aggregate effort, but it decreases the heterogeneity of effort and significantly affects the dynamics of individual behavior. A behavioral model which incorporates a non-monetary utility of winning and relative payoff maximization explains significant over-expenditure of effort. It also suggests that decrease in 'social distance' between group members through social identification promotes pro-social behavior and decreases over-expenditure of effort, while improved information feedback decreases the heterogeneity of effort.

Economic research examining how educational intervention programs affect primary and secondary schooling focuses largely on test scores although the interventions can affect many other outcomes. This paper examines how an educational intervention, a voucher program, affected students' altruism. The voucher program used a lottery to allocate scholarships among low-income applicant families with children in K-8th grade. By exploiting the lottery to identify the voucher effects, and using experimental economic methods, we measure the effects of the intervention on childrens altruism. We also measure the voucher programs effects on parents' altruism and several academic outcomes including test scores. We find that the educational intervention positively affects students' altruism towards charitable organizations but not towards their peers. We fail to find statistically significant effects of the vouchers on parents' altruism or test scores.

An experimental approach is used to examine the performance of three different multi-unit auction designs: discriminatory, uniform-price with fixed supply, and uniform-price with endogenous supply. We find that the strategies of the individual bidders and the aggregate demand curves are inconsistent with theoretically identified equilibrium strategies. The discriminatory auction is found to be more susceptible to collusion than are the uniform-price auctions, and so contrary to theoretical predictions and previous experimental results the discriminatory auction provides the lowest average revenue. Consistent with theoretical predictions, bidder demands are more elastic with reducible supply or discriminatory pricing than in the uniform-price auction with fixed supply. Despite a lack of a priori differences across bidders, the discriminatory auction results in significantly more symmetric allocations.

Time-consuming and costly religious rituals pose a puzzle for economists committed to rational choice theories of human behavior. We propose that either through selection or a causal relationship, the performance of religious rituals is associated with higher levels of cooperation. To test this hypothesis we design field experiments to measure the in-group cooperative behavior of members of religious and secular Israeli kibbutzim, communal societies for which mutual cooperation is a matter of survival. Our results show that religious males (the primary practitioners of collective religious ritual in Orthodox Judaism) are more cooperative than religious females, secular males and secular females. Moreover, the frequency with which religious males engage in collective religious rituals predicts well their degree of cooperative behavior.

We report results from two surveys of representative samples of Americans with private health insurance. The first examines how well Americans understand, and believe they understand, traditional health insurance coverage. The second examines whether those insured under a simplified all-copay insurance plan will be more likely to engage in cost-reducing behaviors relative to those insured under a traditional plan with deductibles and coinsurance, and measures consumer preferences between the two plans. The surveys provide strong evidence that consumers do not understand traditional plans and would better understand a simplified plan, but weaker evidence that a simplified plan would have strong appeal to consumers or change their healthcare choices.

Evidence suggests that contributions to capital campaigns increase with the value of leadership gifts. We examine the response of subjects to the announcement of leadership gifts and its implied change in the campaign's target. The two effects are partitioned.

The public goods problem (Hardin, 1968) either viewed as a problem of extraction or that of contribution has had a long history in the Social Sciences.Our experimental design uses a standard Voluntary Contributions Mechanism (VCM) game with a moderately large group of ten and face-to-face communication. The subjects, who are villagers in the Gori-Ganga Basin of the Central Himalayas, are not re-matched every period.Our results are somewhat different from laboratory experiments using a similar design such as Isaac and Walker (1988a, 1988b). A noteworthy general observation is that even with a relatively low Marginal Per Capita Return (MPCR = 0.2) and a large group we find a steady contribution rate around 55 percent, which diminishes slightly at the end of the session to around 45 percent. We also delve into the demographic characteristics of our subject pool and find that individual contribution to the common pool is determined by gender, age, caste, literacy and history of cooperation in the experiment. However, face-to-face communication is not seen to increase average individual contribution to the common pool.

We report evidence from public goods experiments with and without punishment which we conducted in Russia with 566 urban and rural participants of young and mature age cohorts. Russia is interesting for studying voluntary cooperation because of its long history of collectivism, and a huge urban-rural gap. In contrast to previous experiments we find no cooperation-enhancing effect of punishment. An important reason is that there is substantial spiteful punishment of high contributors in all four subject pools. Thus, spite undermines the scope for self-governance in the sense of high levels of voluntary cooperation that are sustained by sanctioning free riders only.

We present a field experiment to assess the effect of own and peer wage variations on actual work effort of employees with hourly wages. Work effort neither reacts to an increase of the own wage, nor to a positive or negative peer comparison. This result seems at odds with numerous laboratory experiments that show a clear own wage sensitivity on effort. In an additional real-effort laboratory experiment we show that explicit cost and surplus information that enables to exactly calculate employer's surplus from the work contract is a crucial pre-requisite for a positive wage-effort relation. This demonstrates that employee's reciprocity requires a clear assessment of the surplus at stake.

This study showcases the usefulness of field experiments to the study of environmental and resource economics. Our focus pertains to work related to field experiments in the area of 'behavioral' environmental and resource economics. Within this rubric, we discuss research in two areas: those that inform i) benefit cost analysis and ii) conservation of resources. Within each realm, we show how field experiments have been able to test the relevant theories, provide important parameters to construct new theories, and guide policymakers. We conclude with thoughts on how field experiments can be used to deepen our understanding of important areas within environmental and resource economics.

What happens when charities compete? We begin to answer this question through a laboratory experiment in which subjects play two public goods games simultaneously. We systematically vary the incentives for contributing in one of the games - investigating the effects of recognition, a bonus conditional on contributing, and non-monetary sanctions - and measure the effect on contributions in both games. Monetary incentives in the form of conditional bonuses increase contributions, even when two games are played simultaneously. However, non-monetary incentives such as recognition and sanctions are less effective than in related literature on games played in isolation. Moreover, we find mixed evidence of the spillover effect of treatment on the un-treated games - bonuses increase contributions initially, recognition decreases contributions, and sanctions have no effect.
