Two behavioral concepts, loss aversion and mental accounting, have recently been combined to provide a theoretical explanation of the equity premium puzzle. Recent experimental evidence suggests that undergraduate students' behavior is consistent with this "myopic loss aversion" conjecture. Our suspicion is that, much like certain anomalies in the realm of riskless decisions, these behavioral tendencies will be severely attenuated when real market players are put to the task. Making use of a unique subject pool-professional futures and options pit traders recruited from the Chicago Board of Trade-we do find behavioral differences between professionals and students. Yet, rather than discovering that the anomaly disappears, the data suggest that professional traders exhibit myopic loss aversion to a greater extent than undergraduate students.

We overview the use of field experiments in labor economics. We showcase studies that highlight the central advantages of this methodology, which include: (i) using economic theory to design the null and alternative hypotheses; (ii) engineering exogenous variation in real world economic environments to establish causal relations and learning about the underlying mechanisms; and (iii) engaging in primary data collection and often working closely with practitioners. To highlight the potential for field experiments to inform issues in labor economics, we organize our discussion around the individual life cycle. We therefore consider field experiments related to the accumulation of human capital, the demand and supply of labor, behavior within firms, and close with a brief discussion of the nascent literature of field experiments related to household decision-making.

One explanation advanced for the persistent gender pay differences in labor markets is that women avoid salary negotiations. By using a natural field experiment that randomizes nearly 2,500 job-seekers into jobs that vary important details of the labor contract, we are able to observe both the nature of sorting and the extent of salary negotiations. We observe interesting data patterns. For example, we find that when there is no explicit statement that wages are negotiable, men are more likely to negotiate than women. However, when we explicitly mention the possibility that wages are negotiable, this difference disappears, and even tends to reverse. In terms of sorting, we find that men in contrast to women prefer job environments where the 'rules of wage determination' are ambiguous. This leads to the gender gap being much more pronounced in jobs that leave negotiation of wage ambiguous.

Recent discoveries in behavioral economics have led scholars to question the underpinnings of neoclassical economics. We use insights gained from one of the most influential lines of behavioral research -- gift exchange -- in an attempt to maximize worker effort in two quite distinct tasks: data entry for a university library and door-to-door fundraising for a research center. In support of the received literature, our field evidence suggests that worker effort in the first few hours on the job is considerably higher in the "gift" treatment than in the "non-gift treatment." After the initial few hours, however, no difference in outcomes is observed, and overall the gift treatment yielded inferior aggregate outcomes for the employer: with the same budget we would have logged more data for our library and raised more money for our research center by using the market-clearing wage rather than by trying to induce greater effort with a gift of higher wages.

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.

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.

We conducted two matching grant experiments with an international development charity. The primary experiment finds that a matching grant from the Bill and Melinda Gates Foundation raises more funds than a matching grant from an anonymous donor. The effect persists, and is strongest for donors who previously gave to other poverty-oriented charities. Combining these insights with survey results, we conclude that our matching gift primarily works through a quality signal mechanism. Overall, the results help to clarify why people give to charity, what models help to describe those motivations, and how practitioners can leverage economics to increase their fundraising potential.

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.

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.

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.

One fact that has emerged in modern societies is that people help others. Whether it is donating a few dollars to help feed the poor or volunteering time to help rebuild someone's life after a natural disaster, people around the globe commonly lend a hand. This study provides an overview of that support, summarizing gifts of both time and money around the globe. We also highlight research that indicates useful ways in which we can enhance the charitable pie. Our discussion revolves around both individual giving and corporate philanthropy, but we focus on empirical insights from recent charitable fundraising field experiments in the Western World. We present information that is useful for policymakers, fundraising practitioners, and academicians.

This paper examines aggregate time series data on individual charitable donations from 1968 to 2007. We find that changes in individual giving show an asymmetric response to changes in the S&P 500: individuals are more responsive to stock market upturns than downturns.

A critical question facing experimental economists is whether behavior inside the laboratory is a good indicator of behavior outside the laboratory. To address that question, we build a model in which the choices that individuals make depend not just on financial implications, but also on the nature and extent of scrutiny by others, the particular context in which a decision is embedded, and the manner in which participants and tasks are selected. We present empirical evidence demonstrating the importance of these various factors. To the extent that lab and naturally occurring environments systematically differ on any of these dimensions, the results obtained inside and outside the lab need not correspond. Focusing on experiments designed to measure social preferences, we discuss the extent to which the existing laboratory results generalize to naturally-occurring markets. We summarize cases where the lab may understate the importance of social preferences as well as instances in which the lab might exaggerate their importance. We conclude by emphasizing the importance of interpreting laboratory and field data through the lens of theory.

This paper uses county-level panel data to test the appropriateness of the 'one size fits all' reduced-form regression approach commonly used when estimating the economic model of crime. Empirical results provide initial evidence that previous studies, which restrict deterrent effects to have identical impacts across crime types, may be presenting statistically biased results.

Novel empirical insights by their very nature tend to be unanticipated, and in some cases at odds with the current state of knowledge on the topic. The mechanics of statistical inference suggest that such initial findings, even when robust and statistically significant within the study, should not appreciably move priors about the phenomenon under investigation. Yet, a few well-conceived independent replications dramatically improve the reliability of novel findings. Nevertheless, the incentives to replicate are seldom in place in the sciences, especially within the social sciences. We propose a simple incentive-compatible mechanism to promote replications, and use experimental economics to highlight our approach. We begin by reporting results from an experiment in which we investigate how cooperation in allocation games is affected by the presence of Knightian uncertainty (ambiguity), a pervasive and yet unexplored characteristic of most public goods. Unexpectedly, we find that adding uncertainty enhances cooperation. This surprising result serves as a test case for our mechanism: instead of sending this paper to a peer-reviewed journal, we make it available online as a working paper, but we commit never to submit it to a journal for publication. We instead offered co-authorship for a second, yet to be written, paper to other scholars willing to independently replicate our study. That second paper will reference this working paper, will include all replications, and will be submitted to a peer- reviewed journal for publication. Our mechanism allows mutually-beneficial gains from trade between the original investigators and other scholars, alleviates the publication bias problem that often surrounds novel experimental results, and accelerates the advancement of economic science by leveraging the mechanics of statistical inference.

Natural field experiments investigating key labour market phenomena such as unemployment have only been used since the early 2000s. This paper reviews the literature and draws three primary conclusions that deepen our understanding of unemployment. First, the inability to monitor workers perfectly in many occupations complicates the hiring decision in a way that contributes to unemployment. Second, the inability to determine a worker's attributes precisely at the time of hiring leads to discrimination on the basis of factors such as race, gender, age and ethnicity. This can lead to systematically high and persistent levels of unemployment for groups that face discrimination. Third, the importance of social and personal dynamics in the workplace can lead to short-term unemployment. Much of the knowledge necessary for these conclusions could only be obtained using natural field experiments due to their ability to combine randomized control with an absence of experimenter demand effects.

Carefully designed scientific experiments have been an engine of economic, technological, and social progress for well over a century, which is why the public generally trusts such methods. Unfortunately, governments around the world still routinely oppose controlled trials of public policies.
