There has been a dramatic increase in the use of experimental methods in the past two decades. An oft-cited reason for this rise in popularity is that experimental methods provide the necessary control to estimate treatment effects in isolation of other confounding factors. We examine the relevance of experimental findings from laboratory settings that abstract from the field context of the task that theory purports to explain. Using common value auction theory as our guide, we identify naturally occurring settings in which one can test the theory. In our treatments the subjects are not picked at random, as in lab experiments with student subjects, but are deliberately identified by their trading roles in the natural field setting. We find that experienced agents bidding in familiar roles do not fall prey to the winner's curse. Yet, when experienced agents are observed bidding in an unfamiliar role, we find that they frequently fall prey to the winner's curse. We conclude that the theory predicts field behavior well when one is able to identify naturally occurring field counterparts to the key theoretical conditions.

Problems that arise in online markets due to asymmetric information are exacerbated by the fact that transactions in these markets are completely anonymous. The online auction mechanism provided by eBay is an example of such a market. To combat the anonymity problem, eBay allows sellers to become "ID Verified" by paying a small fee to have their identity confirmed by a credit information company. Doing so may reassure potential bidders that the seller is legitimate since their identity is known, and there is more assurance that the seller could be tracked down and punished should a problem arise. Identifying the effect of ID verification is difficult using naturally occurring data, however, because the service tends to be used only by sellers who have a well-established reputation. It is thus difficult to determine whether an improved outcome is due to the seller's reputation or due to ID verification. This study alleviates this concern by conducting a field experiment where items are sold with different IDs that have different characteristics, and finds little evidence that bidders place any value on ID verification.

This paper uses a new panel data set on state-level sulfur dioxide and nitrogen oxide emissions from 1929-1994 to test the appropriateness of the 'one size fits all' reduced-form regression approach commonly used in the environmental Kuznets curve literature. Empirical results provide initial evidence that an inverted-U shape characterizes the relationship between per capita emissions and per capita incomes at the state level. Parameter estimates suggest, however, that previous studies, which restrict cross-sections to undergo identical experiences over time, may be presenting statistically biased results.

Experimental methods were used to examine consumer willingness-to-pay for steak tenderness in a grocery store setting. When relying on a taste test alone to determine product quality, the participants paid an average premium of $1.23/lb for a tender versus tough steak. Fifty-one percent of the participants were willing to pay an average of $1.84/lb when they had completed a taste test and were also provided information about the steak's tenderness. Results indicate that most consumers prefer more tender steaks and that many are willing to pay a premium for tender steaks.

We analyze how overconfidence is affected by superstitious beliefs and emotions induced by positive and negative stimuli in a field experiment involving about 700 Italian students who were randomly assigned to numbered seats in their written examination sessions. According to widespread superstitions, some numbers are considered lucky, while others are considered unlucky. At the end of the examination, we asked students the grade they expected to get. We find that students tend to be systematically overconfident and that their overconfidence is positively affected by being assigned to a lucky number. Interestingly, males and females react differently: on the one hand, females tend to expect lower grades when assigned to unlucky numbers, while they are not affected by being assigned to lucky numbers. On the other hand, males are not affected by being assigned to unlucky numbers but expect higher grades when assigned to lucky numbers.

This article reports the results of several field experiments designed to measure campaign effects in partisan contests. The findings suggest incumbent campaigns failed to increase incumbent vote share, whereas the challenger campaign was effective. To understand these and other results, the incumbent's optimal spending strategy was analyzed theoretically. The analysis reveals that if incumbents maximize their probability of victory rather than vote share, campaigns by typical incumbents are expected to produce only minimal improvement in incumbent vote share. The analysis also explains how returns to campaign spending vary with the competitiveness of the election, how incumbent spending can improve the incumbent's probability of victory yet have only minimal effect on incumbent vote share, and why rational spending plans might decrease the sponsor's expected vote. This article demonstrates the wide scope of application for field experiments and provides an example of how experimental findings can serve as a catalyst for generating theories.

Through good and bad economic times, charitable gifts have continued to roll in largely unabated over the past half century. In a typical year, total charitable gifts of money now exceed 2 percent of gross domestic product. Moreover, charitable giving has nearly doubled in real terms since 1990, and the number of nonprofit organizations registered with the IRS grew by nearly 60 percent from 1995 to 2005. This study provides a perspective on the economic interplay of three types of actors: donors, charitable organizations, and government. How much is given annually? Who gives? Who are the recipients of these gifts? Would changes in the tax treatment of charitable contributions lead to more or less giving? How can charitable institutions design mechanisms to generate the greatest level of gifts? What about the effectiveness of seed money and matching grants?

The effects of cultural framing on behavior in experimental games were explored with a trust game and the Maasai concept of osotua. Maasai use the term osotua to refer to gift-giving relationships based on obligation, need, respect, and restraint. In the trust game, the first player is given money and an opportunity to give any portion of it to the second player. The amount given is then multiplied by the experimenter, and the second player has an opportunity to give any amount back to the first player. Fifty trust games were played by Maasai men at a field site in north central Kenya. Half of the games were played without deliberate framing, and half were framed with the statement, "This is an osotua game." Compared to games with no deliberate framing, those played within the osotua rhetorical frame were associated with lower transfers by both players and with lower expected returns on the part of the first players. Osotua rhetorical framing is also associated with a negative correlation between amounts given by the first player and amounts returned by the second. These results have implications both for the experimental game method and for our understanding of the relationship between culture and behavior.

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.

An information campaign that provided Kenyan teenagers in randomly selected schools with the information that HIV prevalence was much higher among adult men and their partners than among teenage boys led to a 65% decrease in the incidence of pregnancies by adult partners among teenage girls in the treatment group relative to the comparison. This suggests a large reduction in the incidence of unprotected cross-generational sex. The information campaign did not increase pregnancies among teenage couples. These results suggest that the behavioral choices of teenagers are responsive to information on the relative risks of different varieties of a risky activity. Policies that focus only on the elimination of a risky activity and do not address risk reduction strategies may be ignoring a margin on which they can have substantial impact.

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

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.

Models of job tournaments and competitive workplaces more generally predict that while individual effort may increase as competition intensifies between workers, the incentive for workers to cooperate with each other diminishes. We report on a field experiment conducted with workers from a fishing community in Toyama Bay, Japan. Our participants are employed in three different aspects of fishing. The first group are fishermen, the second group are fish wholesalers (or traders), and the third group are staff at the local fishing coop. Although our participants have much in common (e.g., their common relationship to the local fishery and the fact that they all live in the same community), we argue that they are exposed to different amounts of competition on-the-job and that these differences explain differences in cooperation in our experiment. Specifically, fishermen and traders, who interact in more competitive environments are significantly less cooperative than the coop staff who face little competition on the job. Further, after accounting for the possibility of personality-based selection, perceptions of competition faced on-the-job and the treatment effect of job incentives explain these differences in cooperation to a large extent.

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.

In low-income countries, malnutrition is often most sever among infants of six to twenty-four months. They need higher-density foods than the family diet, but density is a credence attribute. We hypothesize that the premium now paid for heavily advertised brands reflects demand for quality assurance, which could be provided at lower cost to competing firms through third-party certification. We use a new market experiment to find that mothers' average willingness-to-pay for certification is about $1.75/kg, for four times its cost, so that total economic-surplus gains from introducing certification to Mali would be on the order of $1 million annually.

Whether rationality of economic behavior increases with expected payoffs and decreases with the cognitive cost it takes to formulate an optimal strategy remains an open question. We explore these issues with field data, using individual bids from sealed-bid auctions in which we sold nearly $10,000 worth of sportscards. Our results indicate that stakes do indeed matter, as high-priced ($70) cards produced more of the theoretically predicted strategic behavior than did lower-priced ($3) cards. We find additional evidence consistent with the importance of cognitive costs, as subjects more experienced with sportscard auctions exhibited a greater tendency to behave strategically than did less experienced bidders.

The functioning and well-being of any society and organization critically hinges on norms of cooperation that regulate social activities. Empirical evidence on how such norms emerge and in which environments they thrive remains a clear void in the literature. To provide an initial set of insights, we overlay a set of field experiments in a natural setting. Our approach is to compare behavior in Brazilian fishermen societies that differ along one major dimension: the workplace organization. In one society (located by the sea) fishermen are forced to work in groups whereas in the adjacent society (located on a lake) fishing is inherently an individual activity. We report sharp evidence that the sea fishermen trust and cooperate more and have greater ability to coordinate group actions than their lake fishermen counterparts. These findings are consistent with the argument that people internalize social norms that emerge from specific needs and support the idea that socio-ecological factors play a decisive role in the proliferation of pro-social behaviors.

We evaluate the impact of three auction mechanisms - the Becker-DeGroot-Marschak mechanism, the second-price auction, and the random nth-price auction - in the measurement of willingness to pay (WTP) and willingness to accept (WTA) measures of value. Our results show that initial bidding in trial 1 in each auction does not contradict the endowment effect; but that, if it is the endowment effect that governs people's initial bidding behavior, it can be eliminated with repetitions of a second-price or random nth-price auction; and if the thesis is that the effect should persist across auctions and across trials is right, our results suggest that there is no fundamental endowment effect.

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.
