This is a review of the literature of field experimental studies of markets. The main results covered by the review are as follows: (1) Generally speaking, markets organize the efficient exchange of commodities; (2) There are some behavioral anomalies that impede efficient exchange; (3) Many behavioral anomalies disappear when traders are experienced.

We study how gradualism -- increasing required levels ("thresholds") of contributions slowly over time rather than requiring a high level of contribution immediately -- affects individuals' decisions to contribute to a public project. Using a laboratory binary choice minimum-effort coordination game, we randomly assign participants to three treatments: starting and continuing at a high threshold, starting at a low threshold but jumping to a high threshold after a few periods, and starting at a low threshold and gradually increasing the threshold over time (the "gradualism" treatment). We find that individuals coordinate most successfully at the high threshold in the gradualism treatment relative to the other two groups. We propose a theory based on belief updating to explain why gradualism works. We also discuss alternative explanations such as reinforcement learning, conditional cooperation, inertia, preference for consistency, and limited attention. Our findings point to a simple, voluntary mechanism to promote successful coordination when the capacity to impose sanctions is limited.

We present results from the first study to examine the causal impact of early childhood education on social preferences of children. We compare children who, at 3-4 years old, were randomized into either a full-time preschool, a parenting program with incentives, or to a control group. We returned to the same children when they reach 7-8 years old a conducted a series of incentivized experiments to elicit there social preferences. We find that early childhood education has a strong causal impact on social preferences several years after the intervention: attending preschool makes children more egalitarian in their fairness view and the parenting program enhances the importance children place on efficiency relative to fairness. Our findings highlight the importance of taking a broad perspective when designing and evaluating early childhood education programs, and provide evidence how differences in institutional exposure may contribute to explaining heterogeneity in social preferences in society.

We investigate determinants of private and public generosity to Katrina victims using an artifactual field experiment. In this experiment, respondents from the general population viewed a short audiovisual presentation that manipulated respondents' perceptions of the income, race, and deservingness of Katrina victims in one of two small cities. Respondents then decided how to split $100 between themselves and a charity helping Katrina victims in this small city. We also collected survey data on subjective support for government spending to help the Katrina victims in the cities. We find, first, that our income manipulation had a significant effect on giving; respondents gave more when they perceived the victims to be poorer. Second, the race and deservingness manipulations had virtually no effect on average giving. Third, the averages mask substantial racial bias among sub-groups of our sample. For instance, the subgroup of whites who identify with their ethnic or racial group strongly biased their giving against blacks. Finally, subjective support for government spending to help Katrina victims was significantly influenced by both our race and deservingness manipulations, but not by the income manipulation. White respondents supported significantly less public spending for black victims and significantly more for victims who were described in more flattering terms, such as being helpful and law-abiding.

Using sportscard grading as an example, we employ field experiments to investigate empirically the informational role of professional certifiers. In the past 20 years, professional grading of sportscards has evolved in a way that provides a unique opportunity to measure the information provision of a monopolist certifier and that of subsequent entrants. Empirical results suggest three patterns: the grading certification provided by the first professional certifier offers new information to inexperienced traders but adds little information to experienced dealers. This implies that the certification may reduce the information asymmetry between informed and uninformed parties. Second, compared with the incumbent, new entrants adopt more precise signals and use finer grading cutoffs to differentiate from the incumbent. Third, our measured differentiated grading cutoffs map consistently into prevailing market prices, suggesting that the market recognizes differences across multiple grading criteria.

Almost a third of US children ages 2-19 are deemed overweight or obese, and part of the problem is the habitual decision to consume high calorie, low nutrient foods. We propose that the school lunchroom provides a 'teachable moment' to engage children in making healthful choices. We conduct a field experiment with over 1,500 participants in grades K-8 and evaluate the impact of small non-monetary incentives on the selection of milk in the school lunchroom. At baseline, only 16% of children select white milk relative to 84% choosing chocolate milk. We find a significant effect of incentives, which increase white milk selection by 2.5 times, to 40%. One concern with incentives is that they may decrease intrinsic motivation to eat healthy, called 'crowd-out of intrinsic motivation.' However, we do not find evidence of 'crowd-out'; rather, we see some suggestive evidence of the positive habit forming effect of incentives.

The use of experimental settings to observe human behaviour in a controlled environment of incentives, rules and institutions, has been widely used by the behavioural sciences for some time now, particularly by psychology and economics. In most cases the subjects are college students recruited from one to two hour decision making exercises in which, depending on their choices, they earn cash averaging US$ 20. In such exercises players face a set of feasible actions, rules and incentives (payoffs) involving different forms of social exchange with other people, and that in most cases involve some kind of externalities with incomplete contracts, such as in the case of common-pool resources situations. Depending on the ecological and institutional settings, the resource users face a set of feasible levels of extraction, a set of rules regarding the control or monitoring of individual use, and sometimes ways of imposing material or non-material costs or rewards to those breaking or following the rules. We brought the experimental lab to the field and invited about two hundred users of natural resources in three Columbian rural villages to participate in such decision making exercises and through these and other research instruments we learned about the ways they solve - or fail to - tragedies of the commons with different social institutions. Further, bringing the lab to the field allowed us to explore some of the limitations of existing models about human behavior and its consequences for designing policies for conserving ecosystems and improving social welfare.

This note presents the results obtained after the first year of a two-year randomized evaluation of a computer assisted learning (CAL) program in Vadodara, India. The CAL program, implemented by a NGO, took advantage of the donation of four computers to each municipal primary school in Vadodara by the state government. The program provided each child in the fourth standard with two hours of shared computer time in which students played educational games that reinforced mathematics competencies ranging from the standard 1 to the standard 3 level. We find the program to be quite effective. On average, it increased math scores by 0.37 standard deviations. The program effect is slightly higher at the bottom of the distribution but persists throughout the distribution. The program had no apparent spillover on language competencies.

The gold standard in the sciences is uncovering causal relationships. A growing literature in economics utilizes field experiments as a methodology to establish causality between variables. Taking lessons from the economics literature, this study provides an "A-to-Z" description of how to conduct field experiments in accounting and finance. We begin by providing a user's guide into what a field experiment is, what behavioral parameters field experiments identify, and how to efficiently generate and analyze experimental data. We then provide a discussion of extant field experiments that touch on important issues in accounting and finance, and we also review areas that have ample opportunities for future field experimental explorations. We conclude that the time is ripe for field experimentation to deepen our understanding of important issues in accounting and finance.

Economists are increasingly turning to the experimental method as a means to estimate causal effects. By using randomization to identify key treatment effects, theories previously viewed as untestable are now scrutinized, efficacy of public policies are now more easily verified, and stakeholders can swiftly add empirical evidence to aid their decision-making. This study provides an overview of experimental methods in economics, with a special focus on developing an economic theory of generalizability. Given that field experiments are in their infancy, our secondary focus pertains to a discussion of the various parameters that they identify, and how they add to scientific knowledge. We conclude that until we conduct more field experiments that build a bridge between the lab and the naturally-occurring settings of interest we cannot begin to make strong conclusions empirically on the crucial question of generalizability from the lab to the field.

The work of Friedrich Von Hayek contains several testable predictions about the nature of market processes. Vernon Smith termed the most important one the "Hayek hypothesis:" equilibrium prices and the gains from trade can be achieved in the presence of diffuse, decentralized information, and in the absence of price-taking behavior and centralized market direction. Vernon Smith tested this by surveying data on laboratory experimental markets and found strong support. We repeat this exercise using field experimental market data. Using field experiments allows us to test several other predictions. Generally speaking, we find support for Hayek's theories.

Property taxes play a central role in the financing of municipal government services. Yet, municipal governments commonly confront problems with property tax collection even when the tax base is known. There is surprisingly little evidence on what authorities can do to increase property tax compliance. This paper analyzes seven different property tax notification strategies through a randomized controlled experiment conducted with the City of Philadelphia. All seven notification strategies increase property tax compliance over the usual approach of simply sending a bill. The most effective notifications are the those that threaten to take out a lien on the property or to foreclose by sheriff's sale for continued failure to pay taxes. The results suggest that economic motives to pay property taxes are more effective than those that appeal to social norms.

It is common in organizational life to be simultaneously involved in multiple collective actions. These collective actions may be modeled using public good dilemmas. The developing social dilemma literature has two perspectives - the "divided loyalties" and "conditional cooperation" perspectives - that give opposite predictions about how individuals will behave when they simultaneously play two identical public good games. The current paper creates consensus between these social dilemma perspectives by examining cooperative behavior of participants interacting in two public good games with either different or the same group members. In each round, individuals have a common budget constraint across the two games. In support of the conditional cooperator's perspective of social dilemmas, we find that playing two games with different, rather than same, group members increases overall contributions. Over the course of the experiment, participants playing two games with different group members shift their contributions significantly more often toward more cooperative public good games than participants playing with the same group members.

Nonparametric estimators provide a flexible means of uncovering salient features of auction data. Although these estimators are popular in the literature, many key features necessary for proper implementation have yet to be uncovered. Here we provide several suggestions for nonparamteric estimation of first-price auction models. Specifically, we show how to impose monotonicity of the equilibrium bidding strategy; a key property of structural auction models not guaranteed in standard nonparametric estimation. We further develop methods for automatic bandwidth selection. Finally, we discuss how to impose monotonicity in auctions with differering number of bidders, reserve prices, and auction-specific characteristics. Finite sample performance is examined using simulated data as well as experimental auction data.

Recent evidence from laboratory experiments suggests that important disparities exist between willingness to pay (WTP) and compensation demanded for the same good. Because a fundamental postulate in neoclassical theory is that with small income effects and many available substitutes, the willingness to accept (WTA) and WTP measures of value for a commodity should be roughly equivalent, this finding has vast implications in both a positive and normative sense. This study advances, and experimentally tests, a new explanation of the WTP/WTA disparity-a dynamic theory based on the presence of commitment costs. Although to date neoclassical models have not explained the observed data patterns well, we find that the commitment cost theory combined with a simple behavioral anomaly is able to lend insights into the causes and severity of the WTA/WTP disparity. Furthermore, we find that market experience attenuates the behavioral anomaly, consistent with the notion that no value disparity exists for agents with sufficient market experience.

An important public policy question that remains unresolved is whether devolution will enhance sensible policy making by exploiting informational asymmetries or, instead, trigger a "beggar thy neighbor" response and stimulate free riding amongst localities. We analyze this question within the framework of U.S. environmental policy making by scrutinizing a unique panel data set on state-level endangered species expenditure patterns. Our empirical estimates are consistent with the notion that states free ride, which may lead to an expenditure equilibrium that is not Pareto efficient.

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.

A hallmark result within behavioral economics is that individuals' choices are affected by current endowments. A recent theory due to Koszegi and Rabin (2006) explains such endowment effect with a model of expectations-based reference-dependent preferences. Departing from past work, we conduct complementary experiments to disentangle expectations - verified probabilistic beliefs held by subjects - from other features of endowment - such as "assignment" to a good - hence allowing us to compare the effect of expectations with that of other variations. While mere assignment can affect choices, we do not find a large role in the effect for Koszegi-Rabin expectations.
