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.

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.

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.

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.

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.

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.

Most hypotheses proposed to explain human food sharing address motives, yet most tests of these hypotheses have measured only the patterns of food transfer. To choose between these hypotheses we need to measure people's propensity to share. To do that, I played two games (the Ultimatum and Dictator Games) with Hadza hunter-gatherers. Despite their ubiquitous food sharing, the Hadza are less willing to share in these games than people in complex societies are. They were also less willing to share in smaller camps than larger camps. I evaluate the various food-sharing hypotheses in light of these results.

We assess the effect of two antithetic non-monetary incentive schemes based on grading rules on students' effort, using experimental data. We randomly assigned students to a tournament scheme that fosters competition between paired up students, a cooperative scheme that promotes information sharing and collaboration between students and a baseline treatment in which students can neither compete nor cooperate. In line with theoretical predictions, we find that competition induces higher effort with respect to cooperation, whereas cooperation does not increase effort with respect to the baseline treatment. Nonetheless, we find a strong gender effect since this result holds only for men while women do not react to this type of non-monetary incentives.

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.

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.

There are independent literatures in economics considering tax-price and match-price incentives for giving. The match-price literature has produced well-identified small price elasticities, but scholars have widely questioned whether these estimates can inform tax policy. The tax-price literature in contrast has produced a large range of estimates. Here, we explore and compare these different incentives. First, we consider tax incentives for giving by focusing on a state-level tax credit that creates a convex kink. We use traditional, as well as more novel, kink methods to estimate the tax-price elasticity of giving. Second, a subgroup of donors in our data were temporarily offered a match for their gifts, creating an opportunity to compare tax-price and match-price effects for the same group of donors giving to the same organization at the same time. We find the tax-price elasticity is about -.2. The match-price elasticity is essentially the same. Our results thus suggest a small tax-price elasticity, close to the match-price elasticity, and close to match-price elasticity estimates in the experimental match-price literature. The implication is that in the giving environment we investigate the match-price elasticity is informative for tax policy.

We analyze how overconfidence is affected by superstitious beliefs and emotions induced by positive and negative stimuli in a field experiment involving about 700 Italian students who were randomly assigned to numbered seats in their written examination sessions. According to widespread superstitions, some numbers are considered lucky, while others are considered unlucky. At the end of the examination, we asked students the grade they expected to get. We find that students tend to be systematically overconfident and that their overconfidence is positively affected by being assigned to a lucky number. Interestingly, males and females react differently: on the one hand, females tend to expect lower grades when assigned to unlucky numbers, while they are not affected by being assigned to lucky numbers. On the other hand, males are not affected by being assigned to unlucky numbers but expect higher grades when assigned to lucky numbers.

Eliciting actual donations toward a public good has been proposed as a means of estimating a lower bound to individuals' compensating surplus, and can be accomplished using mail/phone surveys or field experiments. This study shows that when warm-glow is present, the elicitation instrument decreases the transaction costs of donating. This presents an obstacle to using the donation mechanism. As a remedy, we propose the use of a multi-donation mechanism where subjects can direct their donation to alternative public goods. Results from a field experiment confirm this instrument-induced bias can be large, suggesting field experiment practitioners should seriously consider how their experimental procedures may alter economic behavior.

Tests measuring and comparing educational achievement are an important policy tool. We experimentally show that offering students extrinsic incentives to put forth effort on such achievement tests has differential effects across cultures. Offering incentives to U.S. students, who generally perform poorly on assessments, improved performance substantially. In contrast, Shanghai students, who are top performers on assessments, were not affected by incentives. Our findings suggest that in the absence of extrinsic incentives, ranking countries based on low-stakes assessments is problematic because test scores reflect differences in intrinsic motivation to perform well on the test itself, and not just differences in ability.
