Field experiments were conducted with farmers in the Limari Valley of Chile to test extant theory on right-to-choose auctions. Water volumes that differed by reservoir source and time of availability were offered for sale by the research team. The auctions were supplemented by protocols to elicit risk and time preferences of bidders. We find that the right-to-choose auctions raise significantly more revenue than the benchmark sequential auction. Risk attitudes explain a substantial amount of the difference in bidding between auction institutions, consonant with received theory. The auction bidding revealed distinct preferences for water types, which has implications for market re-design.

We conducted a field experiment involving 720 Italian undergraduate students to investigate the existence of gender differences in performance in competitive settings and whether performance is affected by one's opponent gender. The experimental design was aimed at disentangling gender differences in taste for competition from other differences in psychological attitudes, such as self-confidence and risk aversion. Students were invited to undertake a midterm exam under a tournament scheme having as a prize some bonus points to add to the final grade. Students competed in pairs of equal predicted ability but different gender composition. We find that females are as likely as males to take part in the competition and to obtain a good performance. The gender of one's competitor does not play any role in shaping students' behavior. Men and women perform similarly both in the competitive and in the non-competitive environment.

Potential poverty traps among the rural poor suggest a need to reduce poor farmers' vulnerability by stabilizing crop yields and limiting yield losses. Advances in biotechnology will help address this need directly with crops that tolerate climate fluctuation or resist biotic stresses. Evaluating ex ante how farmers will value these "poor" seeds is important for delivery design, but also challenging. This paper describes an experimental economic approach to understanding farmers' valuation of such seeds. Using data from a survey and experiment, I assess Indian farmers' valuation of changes in the mean, variance, and skewness of payoff distributions. These farmers value increases in expected value, but seem indifferent about higher moment changes in payoff distributions. Farmer traits such as wealth and risk exposure affect their valuation of these changes only mildly. While various limitations to the experimental approach must qualify practical implications of these findings, the experiment demonstrates the viability of conducting valuation experiments with open-ended questions in developing countries.

I present experimental evidence on the effects of minimum bids in first-price, sealed-bid auctions. The auction experiments manipulated the minimum bids in a preexisting market on the Internet for collectible trading cards from the game Magic: the Gathering. I examine a number of outcomes, including the number of participating bidders, the probability of sale, the levels of individual bids, and the auctioneer's revenues. The benchmark theoretical model is one with symmetric, risk-neutral bidders with independent private values. The results verify a number of the predictions concerning equilibrium bidding. Many bidders behave strategically, anticipating the effects of the reserve price on others' bids.

Firms spend billions of dollars annually on new product and label designs in order to attract and retain customers. The issue of labeling is also important to government agencies and nonprofit labeling organizations. For example, the U.S. Food and Drug Administration has an organizational body in its Office of Nutritional Products that deals with issues of food and dietary supplement labeling. The U.S. Department of Agriculture's Food Safety and Inspection Service also deals with labeling through its Labeling and Consumer Protection Staff. These government agencies spend millions of dollars trying to ensure that food labels adequately inform consumers. One issue that has not been examined is the welfare difference to consumers from alternative labeling schemes/regulations. It seems likely that different labels would differ in effectiveness at informing consumers.

We explore the value of the strategy method to field experimentalists. Specifically, we demonstrate that, while the method may lead to reductions in subject understanding, it also generates valuable insights. We played the Third Party Punishment Game and the Generalized Trust Game with Ethiopian medical and nursing students applying the strategy method to the responding role in each case. Then, making use of two proxy measures for the students` cognitive abilities, we investigate the relationship between strategy-type choices and subject understanding. Thus, we find support for the assertion that apparently random and internally inconsistent strategies are symptomatic of problems of cognition. We also find support for the often, implicitly made assumption that, in BDM-type trust games, the ratio of what is returned to what is sent is an appropriate focus for comparative analyses of responder behaviour. Finally, we find evidence that an observed difference in third party punishing behaviour between Swiss and Ethiopian students is due, not to misunderstanding, but to variations in what is perceived as punishable. Our results lead us to conclude that the strategy method is of considerable value in Third Party Punishment Games, but need not be routinely applied in BDM-type trust games.

Charitable giving has been about 2% of US GDP since the turn of the century. A popular fundraising tool is donation matching where every dollar is matched by a third party. But field experiments find that matching does not always increase donations. This may occur because individuals believe that peer donors will exhaust the matching funds. We develop a theory of how beliefs about peers' donations affect one's own likelihood of donation. We test our theory using novel "threshold match" treatments in field and laboratory experiments. These treatments form small groups and offer a flat matching bonus if a threshold number of donations is received. One "threshold match" treatment more than doubles the donation rate in the field relative to no match. To better understand the mechanism behind this huge increase, we use a lab study to replicate the field results and further show that beliefs about peers' donations matter. Our theoretical, lab, and field results combined suggest people are more likely to donate when they believe they are more pivotal to securing matching money. Beliefs about others matter, and they should be taken into account when trying to increase donations.

Domestic attempts to use financial incentives for teachers to increase student achievement have been ineffective. In this paper, we demonstrate that exploiting the power of loss aversion--teachers are paid in advance and asked to give back the money if their students do not improve sufficiently--increases math test scores between 0.201 (0.076) and 0.398 (0.129) standard deviations. This is equivalent to increasing teacher quality by more than one standard deviation. A second treatment arm, identical to the loss aversion treatment but implemented in the standard fashion, yields smaller and statistically insignificant results. This suggests it is loss aversion, rather than other features of the design or population sampled, that leads to the stark differences between our findings and past research.

Preference reversal, or choice/reservation-price inconsistency, has been documented experimentally for certain types of lotteries. We argue that the relevance of these findings for real-world markets is uncertain because the type of objects used cannot exist on a market and because the extent to which the subjects had any real interest in the objects is unknown. Using real-world lotteries, we have tested choice/price consistency on subjects who prefer lotteries to cash. Preference reversal was observed, but the frequency was much lower than in earlier experiments. There were no differences between subjects who qualify as ""lottery interested"" and those who did not.

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.

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.

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.

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.

Auction theory has recently revealed that multi-unit uniform-price auctions, such as those used by the U.S. Treasury for debt sales, entail demand-reduction incentives that can cause inefficient allocations. Recent experimental results show that bidders do indeed strategically reduce their bids in uniform-price auctions. The present paper extends this work, both theoretically and experimentally, to consider the effects of varying numbers of bidders. We derive several theoretical predictions, including the result that demand reduction should decrease with increasing numbers of bidders, though some demand reduction remains even in the asymptotic limit. We then examine the bidding behavior of subjects in this environment by auctioning dozens of Cal Ripken, Jr. baseball cards using both uniform-price and Vickrey auction formats. The field data are broadly consistent with the theoretical predictions of our model: most notably, demand reduction on second-unit bids becomes much smaller and harder to detect as the number of bidders increases.

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.

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.

We carry out a randomized experiment involving undergraduate students enrolled at an Italian University attending two introductory economics classes to evaluate the impact on achievement of examination frequency and interim feedback provision. Students in the treated group were allowed to undertake an intermediate exam and were informed about the results obtained, while students in the control group could only take the final exam. The results show that students undertaking the intermediate exam perform better both in terms of the probability of passing the exams and of grades obtained. High ability students appear to benefit more from the treatment. The experiment design allows us to disentangle "workload division or commitment" effects from "feedback provision" effects. We find that the estimated treatment impact is due exclusively to the first effect, while the feedback provision has no positive effect on performance. Finally, the better performance of treated students in targeted examinations seems not to be obtained at the expenses of results earned in other examinations.

Exploiting new data from a survey and behavioral experiment conducted in Peru we analyze individuals' preferences for securing income in old age. We identify a group that is unrationed by the mandate to save in Peru's pension system, and draw insights from their affiliation and contribution behavior. Among the unrationed, those who are more tolerant of risk, have more children, and have a greater share of housing in their accumulated assets are less likely to affiliate and/or contribute to the formal pensions system. Further, the less risk tolerant choose private individual retirement accounts over a publicly administered pension system.
