Social scientists have recently explored how framing of gains and losses affects productivity. We conducted a field experiment in peri-urban Uganda, and compared output levels across 1000 workers over isomorphic tasks and incentives, framed as either losses or gains. We find that loss aversion can be leveraged to increase the productivity of labor. The estimated welfare costs of using the loss contract are quite modest -- perhaps because the loss contract is viewed as a (soft) commitment device.

Social scientists have presented evidence that suggests discrimination is ubiquitous: women, nonwhites, and the elderly have been found to be the target of discriminatory behavior across several labor and product markets. Scholars have been less successful at pinpointing the underlying motives for such discriminatory patterns. We employ a series of field experiments across several market and agent types to examine the nature and extent of discrimination. Our exploration includes examining discrimination based on gender, age, sexual orientation, race, and disability. Using data from more than 3000 individual transactions, we find evidence of discrimination in each market. Interestingly, we find that when the discriminator believes the object of discrimination is controllable, any observed discrimination is motivated by animus. When the object of discrimination is not due to choice, the evidence suggests that statistical discrimination is the underlying reason for the disparate behavior.

People respond to those who ask. Within the charitable fundraising community, the power of the ask represents the backbone of most fundraising strategies. Despite this, the optimal design of communication strategies has received less formal attention. For their part, economists have recently explored how communication affects empathy, altruism, and giving rates to charities. Our study takes a step back from this literature to examine how suggestions-a direct ask for a certain amount of money-affect giving rates. We find that our suggestion amounts affect both the intensive and extensive margins: more people give and they tend to give the suggested amount. Resulting insights help us understand why people give, why messages work, and deepen practitioners' understanding of how to use messages to leverage more giving.

This study explores the linkages between trade policy, corruption, and environmental policy. We begin by presenting a theoretical model that produces several testable predictions, including: (i) the effect of trade liberalization on the stringency of environmental policy depends on the level of corruption; and (ii) corruption reduces environmental policy stringency. Using panel data from a mix of developed and developing countries from 1982 to 1992, we find evidence that supports these conjectures. We view these results as representing an attempt at understanding the myriad of complex relationships that exist in an open economy.

People often demand a greater price when selling goods that they own than they would pay to purchase the same goods- a well-known economic bias called the endowment effect. The endowment effect has been found to be muted among experienced traders, but little is known about how trading experience reduces the endowment effect. We show that when selling, experienced traders exhibit lower right anterior insula activity, but no differences in nucleus accumbens or orbitofrontal activation, compared with inexperienced traders. Furthermore, insula activation mediates the effect of experience on the endowment effect. Similar results are obtained for inexperienced traders who are incentivized to gain trading experience. This finding indicates that frequent trading likely mitigates the endowment effect indirectly by modifying negative affective responses in the context of selling.

Play in the traditional trust experiment depends both on trust beliefs and on levels of risk aversion. We ran two experiments with a diverse set of subjects in fifteen villages of rural Paraguay, the traditional trust experiment and a new experiment measuring only risk aversion. We find that risk attitudes are highly predictive of play in the trust game. In addition, omitting risk aversion as a regressor in trust regressions signficiantly changes the coefficients of important explanatory variables such as gender and wealth. We also use data on income and bet choice to calculate players' coefficients of relative risk aversion.

We examine the degree of trust and trustworthiness in an experimental trust game with 662 participants from six different age groups, ranging from 8-year-olds to retired persons. Although both trust and trustworthiness have been identified as fundamental pillars for efficient economic interactions, economic research has devoted little attention to measuring their strength in different age groups. In our experiment subjects interact with members of the same age group. We find that trust increases almost linearly from early childhood to early adulthood, but stays rather constant within different adult age groups. Trustworthiness prevails in all age groups.

Successful field tests were conducted on two new Information Aggregation Mechanisms (IAMs). The mechanisms collected information held as intuitions about opening weekend box office revenues for movies in Australia. Participants were film school students. One mechanism is similar to parimutuel betting that produces a probability distribution over box office amounts. Except for "art house films", the predicted distribution is indistinguishable from the actual revenues. The second mechanism is based on guesses of the guesses of others and applied when incentives for accuracy could not be used. It tested well against data and contains information not encompassed by the first mechanism.

We designed a commitment savings product for a Philippine bank and implemented it using a randomized control methodology. The savings product was intended for individuals who want to commit now to restrict access to their savings, and who were sophisticated enough to engage in such a mechanism. We conducted a baseline survey on 1777 existing or former clients of a bank. One month later, we offered the commitment product to a randomly chosen subset of 710 clients; 202 (28.4 percent) accepted the offer and opened the account. In the baseline survey, we asked hypothetical time discounting questions. Women who exhibited a lower discount rate for future relative to current tradeoffs, and hence potentially have a preference for commitment, were indeed significantly more likely to open the commitment savings account. After twelve months, average savings balances increased by 81 percentage points for those clients assigned to the treatment group relative to those assigned to the control group. We conclude that the savings response represents a lasting change in savings, and not merely a short-term response to a new product.

Recent research on ultimatum bargaining, the fact that children often confront and use ultimatums, and theories of developmental psychology all combine to suggest that studying children's ultimatum behavior will be particularly enlightening, both theoretically and with respect to the development of bargaining behavior. The results from two experiments indicate that younger children made larger offers and accepted smaller offers than older participants. Boys took greater strategic advantage of asymmetric information than girls; this dichotomy began with nine-year-olds (third graders) and continued for twelve- and fifteen-year-olds (sixth and ninth graders) as well as for college students. Like adults, children accepted smaller offers when they did not know how much was being divided. Older children required increasingly higher offers, except for college students who were willing to accept considerably less than others. Also, some of the nine-year-olds displayed an extremely strong sense of fairness. The discussion focuses on the development of bargaining strategies and concerns for fairness.

This paper studies the impact of reservation for women on the performance of policy makers and on voters' perceptions of this performance. Since the mid 1990's, one third of Village Council head positions in India have been randomly reserved for a woman: In these councils only women could be elected to the position of chief. Village Councils are responsible for the provision of many local public goods in rural areas. Using a data set which combines individual level data on satisfaction with public services with independent assessments of the quality of public facilities, we compare objective measures of the quantity and quality of public goods, and information about how villagers evaluate the performance of male and female leaders. Overall, villages reserved for women leaders have more public goods, and the measured quality of these goods is at least as high as in non-reserved villages. Moreover, villagers are less likely to pay bribes in villages reserved for women. Yet, residents of villages headed by women are less satisfied with the public goods, including goods that are beyond the jurisdiction of the Panchayat. This may help explain why women rarely win elections even though they appear to be at least as effective leaders along observable dimensions, and are less corrupt.

This article reports results of a field experiment in which two hundred e-mails were sent to authors of recent articles in economics that had promised to send the interested reader supplementary material, such as alternative econometric specifications, "upon request." The e-mails were sent either by a researcher affiliated at Columbia University, New York or the University of Warsaw, Poland; furthermore, the authors' position (assistant professor) was specified in half the e-mails only. Overall, 64% of the approached authors responded to our message, of which two thirds (44% of the entire sample) delivered the requested materials. The frequency and speed of responding and delivering were very weakly affected by the position and affiliation of the sender. Gender of affiliation of the author, number of citations or journal impact factory or the type of object in question seemed to make no difference. However, authors of published articles were much more likely to share than authors of working papers.

Survey researchers have long been concerned with the question of whether participation in preelection surveys increases voter turnout. This article presents findings from three large-scale field experiments conducted during the 2002 general election in Maryland, New York, and Pennsylvania. Unlike early studies, which found that participation in preelection surveys increased voter turnout, this study finds no significant effect. The author argues that the rigorous experimental methodology and large sample size in these three experiments should allay concern that survey participation affects turnout.

We employ a two-step modified count data model to determine the county-level attributes that are conducive to attracting new foreign plants. Our estimation results indicate that previous counts of foreign direct investment, market size and accessibility, and land area are positively related to Foreign Direct Investment (FDI) occurrences; while higher input costs deter new foreign firm entry. Contrary to anecdotal evidence, our results suggest that stringent environmental regulations do not have a negative impact on FDI inflows. These findings have significant implications for policymakers, as flows of FDI are expected to increase dramatically given the economic integration of our global economy.

We implement a public goods game and a social intervention modeled after a public goods game in rural Sierra Leone near the Gola Forest Reserve. We also collect demographic, economic and forest conservation data on households in the area. We use this data to assess the mapping of social preferences from the artefactual field experiment (AFE) into real world behavior. We find evidence of heterogeneity in shifting factors between the AFE, the field experiment, and conservation outcomes. We also find evidence that social controls like war violence and witchcraft may explain some of this correlation.

Workplace misbehaviors are often governed by explicit monitoring and strict punishment. Such enforcement activities can serve to lessen worker productivity and harm worker morale. We take a different approach to curbing worker misbehaviour - bonuses. Examining more than 6500 donor phone calls across more than 80 workers, we use a natural field experiment to investigate how different wage contracts influence workers' propensity to break workplace rules in harmful ways. Our findings show that even though standard relative performance pay contracts, relative to a fixed wage scheme, increase productivity, they have a dark side: they cause considerable cheating and sabotage of co-workers. Yet, even in such environments, by including an unexpected bonus, the employer can substantially curb worker misbehavior. In this manner, our findings reveal how employers can effectively leverage bonuses to eliminate undesired behaviors induced by performance pay contracts.

Critics of stated preference methods argue that hypothetical bias precludes survey techniques from providing reliable economic values for non-market goods and services, rendering estimation of the total economic benefits of public programs fruitless. This paper explores a relatively new methodology to obtain the total value of non-market goods and services-choice experiments-which conveniently provide information on the purchase decision as well as the characteristic value vector. The empirical work revolves around examining behavior in two very different field settings. In the first field study, we explore hypothetical bias in the purchase decision by eliciting contributions for a threshold public good in an actual capital campaign. To extend the analysis a level deeper, in a second field experiment we examine both the purchase decision and the marginal value vector via inspection of consumption decisions in an actual marketplace. In support of the new valuation design, both field experiments provide some evidence that hypothetical choice experiments combined with ""cheap talk"" can yield credible estimates of the purchase decision. Furthermore, we find no evidence of hypothetical bias when estimating marginal attribute values. Yet, we do find that the ""cheap talk"" component might induce internal inconsistency of subjects' preferences in the choice experiment.

While contingent valuation remains the only option available for measurement of total economic value of nonmarketed goods, the method has been criticized due to its hypothetical nature. We analyze field experimental data to evaluate two ex ante approaches to attenuating hypothetical bias, directly comparing value statements across four distinct referenda: hypothetical, "cheap talk," "consequential," and real. Our empirical evidence suggests two major findings: hypothetical responses are significantly different from real responses; and responses in the consequential and cheap talk treatments are statistically indistinguishable from real responses. We review the potential for each method to produce reliable results in the field.

Questions remain as to whether results from experimental economics are generalizable to real decisions in nonlaboratory settings. Furthermore, questions persist about whether social capital helps mitigate information asymmetries in credit markets. I examine whether behavior in two laboratory games, Trust and a Public Goods, predicts loan repayments to a Peruvian group-lending microfinance program. Since this program relies on social capital to enforce repayment, this tests the external validity of the games. Individuals identified as "trustworthy" by the Trust Game are indeed less likely to default on their loans. No similar support is found for the game's identification of "trusting" individuals.
