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.

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 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.

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.

In this paper, we design and field a low-cost, easily-replicable financial education program called "Five Steps," covering five basic financial planning concepts that relate to retirement. We conduct a field experiment to evaluate the overall impact of "Five Steps" on a probability sample of the American population. In different treatment arms, we quantify the relative impact of delivering the program through video and narrative formats. Our results show that short videos and narratives (each takes about three minutes) have sizable short-run effects on objective measures of respondent knowledge. Moreover, keeping informational content relatively constant, format has significant effects on other psychological levers of behavioral change: effects on motivation and self-efficacy are significantly higher when videos are used, which ultimately influences knowledge acquisition. Follow-up tests of respondents' knowledge approximately eight months after the interventions suggest that between one-quarter and one-third of the knowledge gain and about one-fifth of the self-efficacy gains persist. Thus, this simple program has effects both in the short run and medium run.

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.

Both private and public organizations constantly grapple with incentive schemes to induce maximum effort from agents. We begin with a theoretical exploration of optimal contest design, focusing on the number of competitors. Our theory reveals a critical link between the distribution of luck and the number of contestants. We find that if there is considerable (little) mass on good draws, equilibrium effort is an increasing (decreasing) function of the number of contestants. Our first test of the theory implements a laboratory experiment, where important features of the theory can be exogenously imposed. We complement our lab experiment with a field experiment, where we rely on biological models complemented by economic models to inform us of the relevant theoretical predictions. In both cases we find that the theory has a fair amount of explanatory power, allowing a deeper understanding of how to effectively design tournaments. From a methodological perspective, our study showcases the benefits of combining data from both lab and field experiments to deepen our understanding of the economic science.

We introduce a simple, easy to implement instrument for jointly eliciting risk and ambiguity attitudes. Using this instrument, we structurally estimate a two-parameter model of preferences. Our findings indicate that ambiguity aversion is significantly overstated when risk neutrality is assumed. This highlights the interplay between risk and ambiguity attitudes as well as the importance of joint estimation. In addition, over our stakes levels we find no difference in the estimated parameters when incentives are real or hypothetical, raising the possibility that a simple hypothetical question can provide insights into an individuals preferences over ambiguity in such economic environments.

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.

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.

This study identifies a severe gap between the financial backlash borrowers believe awaits them after strategic mortgage default and the reality that lenders rarely pursue deficiency judgments. This coupled with the social norm finding that borrowers widely view strategic default as immoral, leads us to recommend lenders and policymakers seeking to stem the tide of defaults to pursue a policy of informational opacity. We make several recommendations for how to carry out such a policy as well as what might need to change in society before the alternative policy of informational transparency becomes ideal.

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 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.

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.

Food security, along with growing population and the associated environmental concerns, make food waste and loss a central topic in economic analysis. While food losses occur mostly at the production, postharvest and processing phases of the supply chain, food waste takes place mainly at the end of the chain and therefore concerns primarily the habits and behaviour patterns of retailers and consumers. Many solutions and practices have been proposed and oftentimes implemented in order to "keep food out of landfills", thus reducing food waste at the source. However, little attention has been paid to the possible sharing of consumer-side food surplus. In this context, food sharing could represent an effective way to tackle food waste at the consumers' level, with both environmental and economic potential positive effects. Currently, several initiatives and start-ups are being developed in the US and Europe, involving the collection and use of the excess of food from consumers and retailers and the promotion of collaborative consumption models (e.g. Foodsharing, Growington, Feastly, etc.). Nevertheless, there is still little empirical evidence testing the effectiveness of introducing sharing economy approaches to reduce food waste. This study seeks to fill this gap through a framed field experiment. We run two experimental treatments; in the control treatment students were asked to behave according to their regular food consumption habits, and in the food sharing treatment the same students were instructed to purchase food, cook and consume it collectively. Preliminary results showed that the adoption by households of food sharing practices do not automatically translate into food waste reduction. A number of factors (environmental and economic awareness, domestic skills and collaborative behaviors) might act as 'enablers' to make sharing practices effective.

This paper reports results from a field experiment conducted to study the effect of incentives offered to high school teens to motivate them to visit art museums. A vast literature exists on the design of incentives to modify the behavior of firms and consumers, but not much is known about incentives offered to adolescents and young adults to affect their cultural consumption behavior. Students in the first treatment receive a flier with basic information and opening hours of a main museum in Florence, Italy-Palazzo Vecchio. Students in the second treatment receive the flier and a short presentation conducted by an art expert about the exhibit; students in the third treatment, in addition to the flier and the presentation, receive also a non-financial reward in the form of extra-credit points toward their school grade. The analysis yields two main findings. First, non-financial reward is more effective at inducing the students to undertake the encouraged visit than either the simple presentation or the basic information with the flier. Second, over a longer time horizon the non-financial reward does not induce a significant change in behavior with respect to the simple presentation.

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.

This paper reports a surprising finding from an experiment on giving to welfare recipients. The experiment tests how offers of money in n-donor dictator games are affected by 1) donors' humanitarian and egalitarian values and 2) direct information about the recipients' work-preferences. People who are self-reported humanitarians and egalitarians have giving that is highly elastic with respect to the apparent worthiness of the recipient. Among high scoring humanitarian-egalitarians, the median offer to a recipient who appeared industrious was $5.00, while the median offer to a recipient who appeared lazy was only $1.00. Among low scoring humanitarian-egalitarians, the median offer was $1.00 in both conditions. I refer to this combination of altruism and equity/reciprocity as empathic responsiveness. This finding can be rationalized by a model of inequity aversion.
