Walrasian tatonnement has been a fundamental assumption in economics ever since Walras' general equilibrium theory was introduced in 1874. Nearly a century after its introduction, Vernon Smith relaxed the Walrasian tatonnement assumption by showing that neoclassical competitive market theory explains the equilibrating forces in ""double- auction"" markets. I make a next step in this evolution by exploring the predictive power of neoclassical theory in decentralized naturally occurring markets. Using data gathered from two distinct markets--the sports card and collector pin markets--I find a tendency for exchange prices to approach the neoclassical competitive model prediction after a few market periods.

Default options have been shown to affect behavior in a variety of economic choice tasks, including health care and retirement savings. Less research has tested whether defaults affect behavior in the domain of energy efficiency. This study uses data from a randomized controlled experiment in which the default settings on office thermostats in an OECD office building were manipulated during the winter heating season, and chosen thermostat setting observed over a six week period. Using difference-in-differences, panel, and censored regression models (to control for maximum allowable thermostat settings), we find that small decreases in the default led to a greater reduction in chosen settings than large decreases. We also find that office occupants who are more apt to adjust their thermostats prior to the intervention were less susceptible to the default. We find no evidence that offices with multiple occupants displayed different patterns in thermostat choices than single-occupant offices. We conclude that this kind of intervention can increase building energy efficiency, and discuss broader policy implications of our findings.

Economists well understand that the work of Friedrich Hayek contains important theoretical insights. It is less often acknowledged that his work contains testable predictions about the nature of market processes. Vernon Smith termed the most important one the 'Hayek hypothesis': that gains from trade can be realized in the presence of diffuse, decentralized information, and in the absence of price-taking behavior and centralized market direction. Vernon Smith tested this prediction by surveying data on laboratory experimental markets and found strong support. We extend Smith's work first by showing how subsequent theoretical advances provide a theoretical foundation for the Hayek Hypothesis. We then test the hypothesis using recent field experimental market data. Using field experiments allows us to test several other predictions from Hayek, such as that market experience increases the realized gains from trade. Generally speaking, we find support for Hayek's theories.

Using a natural field experiment with factory workers where we introduce a quantity-based performance-pay scheme in addition to their base salary, we quantify the impact of one-dimensional monetary incentives on both incentivized (quantity) and non-incentivized (quality) dimensions of output. While the management typically observes only quantity, we also observe quality by hiring quality-inspectors unbeknownst to the workers. While some workers receive a flat-rate base salary, others receive a piece-rate base salary. We find sharp evidence that workers under a flat-rate base salary trade off quality for quantity. Interestingly, this quantity-quality trade-off is statistically insignificant for workers under a piece-rate base salary. This variation in the treatment effect is consistent with a simple theoretical model that predicts that when agents are already incented at the margin, the quantity-quality trade-off resulting from additional incentives will be less prominent.

A well-recognized problem in the multitasking literature is that workers might substantially reduce their effort on tasks that produce unobservable outputs as they seek the salient rewards to observable outputs. Since the theory related to multitasking is decades ahead of the empirical evidence, the economic costs of standard incentive schemes under multitasking contexts remain largely unknown. This study provides empirical insights quantifying such effects using a field experiment in Chinese factories. Using more than 2200 data points across 126 workers, we find sharp evidence that workers do trade off the incented output (quantity) at the expense of the non-incented one (quality) as a result of a piece rate bonus scheme. Consistent with our theoretical model, treatment effects are much stronger for workers whose base salary structure is a flat wage compared to those under a piece rate base salary. While the incentives result in a large increase in quantity and a sharp decrease in quality for workers under a flat base salary, they result only in a small increase in quantity without affecting quality for workers under a piece rate base salary.

Recent evidence suggests that participants' misunderstanding of experimental auction mechanisms can systematically bias auction results. We present a simple technique for testing whether field auction participants fully understand the demand-revealing nature of the auction mechanism and, by extension, whether auction bids provide an unbiased estimate of participants' willingness to pay.

In an earlier paper (Raymond C. Battalio, John H. Kagel, and Don N. Mac Donald, 1985), we reported Allais-type violations of the independence axiom of expected utility theory with rats choosing over positively valued payoffs (food rewards). This note extends this research, examining animals' choices over losses, testing for (1) standard Allais-type common ratio effect violations of expected utility theory and (2) fanning out of indifference curves for random prospects, tests of Mark J. Machina's (1982, 1987) hypothesis II (hereafter H2), over previously unexplored areas of the unit probability triangle. Results from a parallel series of experiments using human subjects choosing over real losses are also reported. For both rats and people, we find standard Allais-type violations of expected utility theory and a systematic failure of the fanning out hypothesis in the southeast corner of the unit probability triangle, in the case of losses. Thus, the fanning out hypothesis (Machina 1982, 1987) cannot provide a satisfactory explanation for behavioral deviations from expected utility theory.

Although there is intense debate about the effect of increased expenditure on education in developed countries, there is widespread consensus that provision of textbooks can substantially increase test scores in developing countries. This paper evaluates a program through which a Dutch non-profit organization provided textbooks to 25 rural Kenyan primary schools that were chosen randomly from a group of 100 candidate schools. After one school year, average test scores did not differ substantially between program and comparison schools. However, for those students in the top quintile of the distribution of initial academic achievement, the program raised test scores by at least 0.2 standard deviations.

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 paper uses a natural field experiment to examine the effectiveness of specific nudges on tax compliance amongst firms and the self-employed in the Dominican Republic. In collaboration with the Dominican Republic's tax authority, we designed messages for more than 28,000 self-employed workers and over 56,000 firms. Leveraging administrative tax data, we find evidence that our nudges (increasing the salience of prison sentences or public disclosure of tax evaders) have large effects on increasing tax compliance, primarily working through the channel of decreasing claimed tax exemptions. Interestingly, we find that firms are more impacted than the self-employed, and that firm size is critically linked to nudge effectiveness: larger firms are considerably more influenced by nudges than smaller firms. We find this latter result noteworthy given the paucity of evidence showing significant behavioral impacts of nudges amongst the largest players in a market. Overall, our messages increased tax revenue by $193 million (roughly 0.23% of the Dominican Republic's GDP in 2018), with over $100 million constituting income that the government would not have received without our field experimental nudges.

We ran a field experiment to investigate whether competing in rank-order tournaments with different prize spreads affects individual performance. Our experiment involved students from an Italian University who took an exam that was partly evaluated on the basis of relative performance. Students were matched in pairs on the basis of their high school grades and each pair was randomly assigned to one of three different tournaments. Random assignment neutralizes selection effects and allows us to investigate if larger prize spreads increase individual effort. We do not find any positive effect of larger prizes on performance. Furthermore, we show that the effect of prize spreads on students' performance depends on their degree of risk-aversion: competing in tournaments with large spreads negatively affects the performance of risk-averse students, while it does not produce any effect on students who are more prone to taking risks.

Childhood obesity has reached epidemic proportions in the U.S., with now almost a third of children ages 2-19 deemed overweight or obese. In this study, we leverage recent findings from behavioral economics to explore new approaches to tackling one aspect of childhood obesity: food choice and consumption. Using a field experiment where we include more than 1,500 children, we report several key insights. First, we find that individual incentives can have large influences: in the control, only 17% of children prefer the healthy snack, whereas the introduction of small incentives increases take-up of the healthy snack to roughly 75%, more than a four-fold increase. There is some evidence that the effects continue after the treatment period, consistent with a model of habit formation. Second, we find little evidence that the framing of incentives (loss versus gain) matters. While incentives work, we find that educational messaging alone has little influence on food choice. Yet, we do observe an important interaction effect between messaging and incentives: together they provide an important influence on food choice. For policymakers, our findings show the power of using incentives to combat childhood obesity. For academics, our approach opens up an interesting combination of theory and experiment that can lead to a better understanding of theories that explain healthy decisions and what incentives can influence them.

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.

Research on behavioral economics has established the importance of factors such as reference dependent preferences, hyperbolic preferences, and the value placed on non-financial rewards. To date, these insights have had little impact on the way the educational system operates. Through a series of field experiments involving thousands of primary and secondary school students, we demonstrate the power of behavioral economics to influence educational performance. Several insights emerge. First, we find that incentives framed as losses have more robust effects than comparable incentives framed as gains. Second, we find that non-financial incentives are considerably more cost-effective than financial incentives for younger students, but were not effective with older students. Finally, and perhaps most importantly, consistent with hyperbolic discounting, all motivating power of the incentives vanishes when rewards are handed out with a delay. Since the rewards to educational investment virtually always come with a delay, our results suggest that the current set of incentives may lead to under-investment. For policymakers, our findings imply that in the absence of immediate incentives, many students put forth low effort on standardized tests, which may create biases in measures of student ability, teacher value added, school quality, and achievement gaps.

The role of the market in mitigating and mediating various forms of behavior is perhaps the central issue facing behavioral economics today. This study designs a field experiment that is explicitly linked to a controlled laboratory experiment to examine whether, and to what extent, social preferences influence outcomes in actual market transactions. While agents drawn from a well-functioning marketplace behave in accord with social preference models in tightly controlled laboratory experiments, when observed in their naturally occurring settings their behavior approaches what is predicted by self-interest theory. In the limit, much of the observed behavior in the marketplace that is consistent with social preferences is due to reputational concerns: suppliers who expect to have future interactions with buyers provide higher product quality only when the buyer can verify quality via a third-party certifier. The data also speak to theories of how reputation effects enhance market performance. In particular, reputation and the monitoring of quality are found to be complements, and findings suggest that the private market can solve the lemons problem through third party verification.

Recent discoveries in behavioral economics have led to important new insights concerning what can happen in markets. Such gains in knowledge have come primarily via laboratory experiments--a missing piece of the puzzle in many cases is parallel evidence drawn from naturally-occurring field counterparts. We provide a small movement in this direction by taking advantage of a unique opportunity to work with a Chinese high-tech manufacturing facility. Our study revolves around using insights gained from one of the most influential lines of behavioral research--framing manipulations--in an attempt to increase worker productivity in the facility. Using a natural field experiment, we report several insights. For example, conditional incentives framed as both "losses" and "gains" increase productivity for both individuals and teams. In addition, teams more acutely respond to bonuses posed as losses than as comparable bonuses posed as gains. The magnitude of the effect is roughly 1%: that is, total team productivity is enhanced by 1% purely due to the framing manipulation. Importantly, we find that neither the framing nor the incentive effect lose their importance over time; rather the effects are observed over the entire sample period. Moreover, we learn that worker reputation and conditionality of the bonus contract are substitutes for sustenance of incentive effects in the long-run production function.

One particularly vexing puzzle for economists and policymakers over the past several decades concerns the empirical significance of the theoretically predicted pollution haven hypothesis. While neoclassical theory and conventional wisdom both surmise that local economies will suffer deleterious effects from stricter environmental regulations, empirical studies have largely failed to validate such claims. This study utilizes the method of matching to show that the impact of stricter regulation is heterogeneous spatially, varying systematically based on location-specific attributes. Previous studies that assume a homogenous response may therefore inadvertently mask the overall impact of more stringent regulations by pooling unaffected and affected regions.

Adults do not play the Nash equilibrium in the well known centipede game. While Palacios-Huerta and Volij (2009) argued that behavior results from the failure of backward induction logic, Levitt et al. (2011) found that players who know how to backward induct still do not play Nash. Here, we ask children and adolescents (ages 8 to 16) to play the centipede game in the laboratory and we leverage knowledge about developing abilities to assess the contribution of backward induction logic. In line with the literature, we find that the ability to perform backward induction increases with age. However, it predicts behavior only in elementary school children: those with advanced logical abilities over-apply their skills. Starting in middle school, students who reason logically know that the unraveling argument should not be applied blindly. They utilize Theory-of-Mind (ToM) abilities to form beliefs about others' play and (optimally) refrain from stopping immediately. Their behavior is in line with the deviations observed in adults. Interestingly, developing ToM leads to a gradual decrease in stopping stages with age, which is accompanied by a decrease in payoffs with age. The results indicate that ToM is the key contributor of behavior that helps departing from backward induction when beneficial.
