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.

Every new method of trade offers an opportunity for economic agents to compare its costs and benefits relative to the status quo. Such comparison motivates sorting across market segments and reshapes the whole marketplace. The Internet provides an excellent example: it introduces substantial search cost savings over brick and mortar retail stores but imposes new obstacles for sellers to convey quality. Using sports card trading as a case study, we provide empirical evidence on (1) the sorting of product quality between the online and offline segments, (2) the changes for retail outlets after the Internet came into place, and (3) how supporting industries such as professional grading and card manufacturing adapted to take advantage of the new market.

The notion of diminishing marginal value had a profound impact on the development of neoclassical theory. Early neoclassical scholars had difficulty convincing contemporaries of the new paradigm's value until political economists used the critical assumption of diminishing marginal value to link utility and demand. While diminishing marginal value remains a key component of modern economic intuition, there is little direct verification of this behavioral property. This paper reports experiments on a myriad of subject pools to examine behavior in both price and exchange settings. We report results from nearly 900 subjects across 19 treatments and find strong evidence of diminishing marginal value.

Motivated by problems of coordination failure observed in weak-link games, we experimentally investigate behavioral spillovers for order-statistic coordination games. Subjects play the minimum- and median-effort coordination games simultaneously and sequentially. The results show the precedent for cooperative behavior spills over from the median game to the minimum game when the games are played sequentially, but not when they are played simultaneously. Moreover, spillover occurs even when group composition changes, although the effect is not as strong. We also find that the precedent for uncooperative behavior does not spill over from the minimum game to the median game. These findings suggest guidelines for increasing cooperative behavior within organizations.

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.

Experimental economics represents a strong growth industry. In the past several decades the method has expanded beyond intellectual curiosity, now meriting consideration alongside the other more traditional empirical approaches used in economics. Accompanying this growth is an influx of new experimenters who are in need of straightforward direction to make their designs more powerful. This study provides several simple rules of thumb that researchers can apply to improve the efficiency of their experimental designs. We buttress these points by including empirical examples from the literature.

In this study, I examine relative private signal strength and find that offered advice is significantly more influential in changing strategic mortgage default proclivity than is observed actions. Moreover, these private signals are more reflective of financial herding than they are of an information cascade. From a policy perspective, herds are easier to reverse than are cascades making more effective policies aimed at curbing the incidence of strategic mortgage default. Interestingly, an informationally equivalent change in private signal strength across actions and advice alters strategic default willingness, but not the moral stance of borrowers, which demonstrates the complexity of this life-altering financially and emotionally impactful decision.

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.

Framing a decision situation differently has affected behavior substantially in previous studies. This paper tests a framing effect in a field experiment at the University of Zurich. Each semester, every student has to decide whether to contribute to two social funds. Students were randomly informed that a high percentage of the student population contributed (or, equivalently, that a low percentage did not contribute), while others received the information that a relatively low percentage contributed (or a high percentage did not contribute). The results show the influence of framing effects is limited. People behave in a conditional cooperative way if informed either about the number of contributors or about the equivalent number of non-contributors. The positive correlation between group behavior and individual behavior is, however, weaker when the focus is on the defectors. The field experiment also shows gender differences in social comparison.

In this paper, we developed and experimentally evaluated four novel educational programs delivered online: an informational brochure, a visual interactive tool, a written narrative, and a video narrative. The programs were designed to inform people about risk diversification, an essential concept for financial decision-making. The effectiveness of these programs was evaluated using the RAND American Life Panel. Participants were exposed to one of the programs, and then asked to answer questions measuring financial literacy and self-efficacy. All of the programs were found to be effective at increasing self-efficacy, and several improved financial literacy, providing new evidence for the value of programs designed to help individuals make financial decisions. The video was more effective at improving financial literacy scores than the written narrative, highlighting the power of online media in financial education.

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.

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.

The literature exploring other regarding behavior sheds important light on interesting social phenomena, yet less attention has been given to how the received results speak to foundational assumptions within economics. Our study synthesizes the empirical evidence, showing that recent work challenges convex preference theory but is largely consistent with rational choice theory. Guided by this understanding, we design a new, more demanding test of a central tenet of economics - the contraction axiom - within a sharing framework. Making use of more than 325 dictators participating in a series of allocation games, we show that sharing choices violate the contraction axiom. We advance a new theory that augments standard models with moral reference points to explain our experimental data. Our theory also organizes the broader sharing patterns in the received literature.

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.

A disadvantage of multiple-choice tests is that students have incentives to guess. To discourage guessing, it is common to use scoring rules that either penalize wrong answers or reward omissions. These scoring rules are considered equivalent in psychometrics, although experimental evidence has not always been consistent with this claim. We model students' decisions and show, first, that equivalence holds only under risk neutrality and, second, that the two rules can be modified so that they become equivalent even under risk aversion. This paper presents the results of a filed experiment in which we analyze the decisions of subjects taking multiple-choice exams. The evidence suggests that differences between scoring rules are due to risk aversion as theory predicts. We also find that the number of omitted items depends on the scoring rule, knowledge, gender, and other covariates.

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.

Information asymmetries are important in theory but difficult to identify in practice. We estimate the empirical importance of adverse selection and moral hazard in a consumer credit market using a new field experiment methodology. We randomized 58,000 direct mail offers issued by a major South African lender along three dimensions: 1) the initial "offer interest rate" appearing on direct mail solicitations; 2) a "contract interest rate" equal to or less than the offer interest rate and revealed to the over 4,000 borrowers who agreed to the initial offer rate; and 3) a dynamic repayment incentive that extends preferential pricing on future loans to borrowers who remain in good standing. These three randomizations, combined with complete knowledge of the Lender's information set, permit identification of specific types of private information problems. Specifically, our setup distinguishes adverse selection from moral hazard effects on repayment, and thereby generates unique evidence on the existence and magnitudes of specific credit market failures. We find evidence of both adverse selection (among women) and moral hazard (predominantly among men), and the findings suggest that about 20% of default is due to asymmetric information problems. This helps explain the prevalence of credit constraints even in a market that specializes in financing high-risk borrowers at very high rates.

About 10% of primary school students in developing countries have poor vision, yet in virtually all of these countries very few children wear glasses. There has been almost no research on the impact of poor vision on school performance in developing countries, and simple OLS estimates are likely to be biased because students who study more often are likely to develop poor vision faster. This paper presents results from a randomized trial in Western China that began in the summer of 2004. The trial involves over 19,000 students in 165 schools in two counties of Gansu province. The schools were randomly divided (at the township level) into 103 schools that received eyeglasses (for students in grades 4-6) and 62 schools that served as controls. The results indicate that, after one year, making eyeglasses available increased average test scores by 0.11 to 0.15 standard deviations (of the distribution of the test scores). For those students who accepted the glasses, average test scores increased by 0.15 to 0.22 standard deviations.

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.
