We implement a public goods game and a social intervention modeled after a public goods game in rural Sierra Leone near the Gola Forest Reserve. We also collect demographic, economic and forest conservation data on households in the area. We use this data to assess the mapping of social preferences from the artefactual field experiment (AFE) into real world behavior. We find evidence of heterogeneity in shifting factors between the AFE, the field experiment, and conservation outcomes. We also find evidence that social controls like war violence and witchcraft may explain some of this correlation.

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.

To further our understanding of the economics of charity, we conducted a natural field experiment. Making use of two direct mail solicitations sent to nearly 20,000 prior donors to a charity, we tested the effectiveness of $1:$1 and $1:$3 matching grants on charitable giving. We find only weak evidence that either of the matches work; in fact, for the full sample, the match only increased giving after the match deadline expired. Yet, the aggregation masks important heterogeneities: those donors who are actively supporting the organization tend to be positively influenced whereas lapsed givers are either not affected or adversely affected. Furthermore, some presentations of the match can do harm, e.g., when an example amount given is high ($75) and the match ratio is below $1:$1. Overall, the results help clarify what might cause people to give and provide further evidence that larger match ratios are not necessarily superior to smaller match ratios.

Tax collection problems date back to the earliest recorded history of mankind. This paper begins with a simple theoretical construct of paying (rather than declaring) taxes, which we argue has been an overlooked aspect of tax compliance. This construct is then tested in two large natural field experiments. Using administrative data from more than 200,000 individuals in the UK, we show that including social norms and public goods messages in standard tax payment reminder letters considerably enhances tax compliance. The field experiments increased taxes collected by the Government in the sample period and were cost-free to implement, demonstrating the potential importance of such interventions in increasing tax compliance.

The wealthiest 10% of donors now give 90% of charitable dollars in the U.S., but little is known about what motivates them. This study uses a natural field experiment, tracking over five thousand high capacity donors, to lend preliminary insights into the world of high capacity givers. On some dimensions, high capacity donors mirror modal donors: there is persistence in giving patterns, signals of program quality influence giving, and the price of giving is not unduly important. Unlike typical small donors, the givers in our data respond only on the intensive margin, and often with a longer time lag. Our study highlights the value to practitioners of partnering with academics, as our intervention has generated $30 million in incremental donations to the University.

Acts of dishonesty permeate life. Understanding their origins, and what mechanisms help to attenuate such acts is an underexplored area of research. This study takes an economics approach to explore the propensity of individuals to act dishonestly across different contexts. We conduct an experiment that includes both parents and their young children as subjects, exploring the roles of moral cost and scrutiny on dishonest behavior. We find that the highest level of dishonesty occurs in settings where the parent acts alone and the dishonest act benefits the child. In this spirit, there is also an interesting, quite different, effect of children on parents' behavior: parents act more honestly under the scrutiny of daughters than under the scrutiny of sons. This finding sheds new light on the origins of the widely documented gender differences in cheating behavior observed among adults, where a typical result is that females are more honest than males.

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.

The tontine, which is an interesting mixture of group annuity, group life insurance, and lottery, has a peculiar place in economic history. In the seventeenth and eighteenth centuries it played a major role in raising funds to finance public goods in Europe, but today it is rarely encountered outside of a dusty footnote in actuarial course notes or as a means to thicken the plot of a murder mystery. This study provides a formal model of individual contribution decisions under a modern variant of the historical tontine mechanism that is easily implemented by private charities. Our model incorporates desirable properties of the historical tontine to develop a mechanism to fund the private provision of a public good. The tontine-like mechanism we derive is predicted to outperform not only the voluntary contribution mechanism but also another widely used mechanism: charitable lotteries. Our experimental test of the instrument provides some evidence of the beneficial effects associated with implementing tontine-like schemes. We find that the mechanism has particular power in cases where agents are risk-averse or in situations where substantial asymmetries characterize individual preferences for the public good.

Whether environmental regulations alter capital flows remains a hotly debated issue. This paper uses county-level data to examine the location decisions of domestic and foreign firms in a single empirical model and tests for asymmetries by firm origin in the degree to which capital flows are influenced by environmental standards. We find that while domestic firms are influenced by environmental regulations, foreign firms are not. Since the benefits of foreign investment are well-documented-foreign plants typically provide more jobs and increase local wages by more than domestic plants-this result suggests a double-dividend is available: foreign plants provide an economic stimulus and are not unduly influenced by environmental protections.

Previous studies have proposed that equilibrium capital flows are affected by environmental regulations-the commonly coined 'pollution haven' hypothesis. We revisit this issue by treating environmental policies as endogenous and allowing governmental corruption to influence foreign direct investment patterns. Via these two simple extensions, we are able to provide a much richer model of international capital flows. The theoretical model presumes that the effect of corruption on FDI operates via two channels: corruption affects capital flows through its impact on environmental policy stringency and due to greater theft of public funds earmarked for public spending. We empirically examine the implications of the model using US state-level panel data from four industrial sectors over the period 1977-1987. Empirical results suggest environmental policy and corruption both play a significant role in determining the spatial allocation of inbound US FDI. In addition, the estimated effect of environmental policy is found to depend critically on exogeneity assumptions.

We test the effect of performance-based incentives on educational achievement in a low-performing school district using a randomized field experiment. High school freshmen were provided monthly financial incentives for meeting an achievement standard based on multiple measures of performance including attendance, behavior, grades and standardized test scores. Within the design, we compare the effectiveness of varying the recipient of the reward (students or parents) and the incentive structure (fixed rate or lottery). While the overall effects of the incentives are modest, the program has a large and significant impact among students on the threshold of meeting the achievement standard. These students continue to outperform their control group peers a year after the financial incentives end. However, the program effects fade in longer term follow up, highlighting the importance of longer term tracking of incentive programs.

An important dialogue between theorists and experimentalists over the past few decades has raised the study of the interaction of psychological and economic incentives from academic curiosity to a bona fide academic field. One recent area of study within this genre that has sparked interest and debate revolves around the "hidden costs" of conditional incentives. This study overlays randomization on a naturally-occurring environment in a series of temporally-linked field experiments to advance our understanding of the economics of charity and test if such "costs" exist in the field. This approach permits us to examine why people initially give to charities, and what factors keep them committed to the cause. Several key findings emerge. First, there are hidden benefits of conditional incentives that would have gone undetected had we maintained a static theory and an experimental design that focused on short run substitution effects rather than dynamic interactions. Second, we can reject the pure altruism model of giving. Third, we find that public good provision is maximized in both the short and long run by using conditional, rather than unconditional, incentives.

Behavioral economics and field experiments within the social sciences have advanced well beyond academic curiosum. Governments around the globe as well as the most powerful firms in modern economies employ staffs of behavioralists and experimentalists to advance and test best practices. In this study, we combine behavioral economics with field experiments to reimagine a new model of early childhood education. Our approach has three distinct features. First, by focusing public policy dollars on prevention rather than remediation, we call for much earlier educational programs than currently conceived. Second, our approach has parents at the center of the education production function rather than at its periphery. Third, we advocate attacking the macro education problem using a public health methodology, rather than focusing on piecemeal advances.

The experimental literature has shown the tendency for experimental trading markets to converge to neoclassical predictions. Yet, the extent to which theory explains the equilibrating forces in markets remains under-researched, especially in the developing world. We set up a laboratory in 94 villages in rural Sierra Leone to mimic a real market. We implement several treatments, varying trading partners and the anonymity of trading. We find that when trading with co-villagers average efficiency is somewhat lower than predicted by theory (and observed in different contexts), and markets do not fully converge to theoretical predictions across rounds of trading. When participants trade with strangers efficiency is reduced more. Anonymizing trade within the village does not affect efficiency. This points to the importance of behavioral norms for trade. Intra-village social relationships or hierarchies, instead, appear less important as determinants of trading outcomes. This is confirmed by analysis of the trader-level data, showing that individual earnings in the experiment do not vary with one's status or position in local networks.

The growth of the "gig" economy generates worker flexibility that, some have speculated, will favor women. We explore one facet of the gig economy by examining labor supply choices and earnings among more than a million rideshare drivers on Uber in the U.S. Perhaps most surprisingly, we find that there is a roughly 7% gender earnings gap among drivers. The uniqueness of our data - knowing exactly the production and compensation functions - permits us to completely unpack the underlying determinants of the gender earnings gap. We find that the entire gender gap is caused by three factors: experience on the platform (learning-by-doing), preferences over where/when to work, and preferences for driving speed. This suggests that, as the gig economy grows and brings more flexibility in employment, women's relatively high opportunity cost of non-paid-work time and gender-based preference differences can perpetuate a gender earnings gap even in the absence of discrimination.

We develop theory and a tightly-linked field experiment to explore the supply side implications of corporate social responsibility (CSR). Our natural field experiment, in which we created our own firm and hired actual workers, generates a rich data set on worker behavior and responses to both pecuniary and CSR incentives. Making use of a novel identification framework, we use these data to estimate a structural principal-agent model. This approach permits us to compare and contrast treatment and selection effects of both CSR and financial incentives. Using data from more than 110 job seekers, we find strong evidence that when a firm advertises work as socially-oriented, it attracts employees who are more productive, produce higher quality work, and have more highly valued leisure time. In terms of enhancing the labor pool, for example, CSR increases the number of applicants by 25 percent, an impact comparable to the effect of a 36 percent increase in wages. We also find an economically important complementarity between CSR and wage offers, highlighting the import of using both to hire and motivate workers. Beyond lending insights into the supply side of CSR, our research design serves as a framework for causal inference on other forms of non-pecuniary incentives and amenities in the workplace, or any other domain more generally.

Field experiments conducted with the village, city, state, region, or even country as the unit of randomization are becoming commonplace in the social sciences. While convenient, subsequent data analysis may be complicated by the constraint on the number of clusters in treatment and control. Through a battery of Monte Carlo simulations, we examine best practices for estimating unit-level treatment effects in cluster-randomized field experiments, particularly in settings that generate short panel data. In most settings we consider, unit-level estimation with unit fixed effects and cluster-level estimation weighted by the number of units per cluster tend to be robust to potentially problematic features in the data while giving greater statistical power. Using insights from our analysis, we evaluate the effect of a unique field experiment: a nationwide tipping field experiment across markets on the Uber app. Beyond the import of showing how tipping affects aggregate outcomes, we provide several insights on aspects of generating and analyzing cluster-randomized experimental data when there are constraints on the number of experimental units in treatment and control.

In modern economies, when debt and trust issues arise, a partial forgiveness policy is often the solution to induce payment and increase disclosure. For their part, governments around the globe continue to use tax amnesties as a strategy to allow debtors to make amends for past misdeeds in exchange for partial debt forgiveness. While ubiquitous, much remains unknown about the basic facts of how well amnesties work, for whom, and why. We present a simple theoretical construct that provides both economic clarity into tax amnesties as well as insights into the necessary behavioral parameters that one must estimate to understand the consequences of tax amnesties. We partner with the Dominican Republic Tax Authorities to design a natural field experiment that is linked to the theory to estimate key causal mechanisms. Empirical results from our field experiment, which covers 125,452 taxpayers who collectively owe $5.2 billion (5.5% of GDP) in known debt, highlight the import of deterrence laws, beliefs about future amnesties, and tax morale for debt payment and increased disclosure. Importantly, we find large short run effects: our most effective treatment (deterrence) increased payments of known debt by 25% and hidden debt by 48%. Further, we find no evidence of our intervention backfiring on subsequent tax payments.
