Laboratory experiments have been used extensively in economics in the past several decades to lend both positive and normative insights into a myriad of important economic issues. This study discusses a related approach that has increasingly grown in prominence of late--field experiments. I argue that field experiments serve as a useful bridge between data generated in the lab and empirical studies using naturally-occurring data. In discussing this relationship, I highlight that field experiments can yield important insights into economic theory and provide useful guidance to policymakers. I also draw attention to an important methodological contribution of field experiments: they provide an empirical account of behavioral principles that are shared across different domains. In this regard, at odds with conventional wisdom, I argue that representativeness of the environment, rather than representative of the sampled population, is the most crucial variable in determining generalizability of results for a large class of experimental laboratory games.

Several experimental studies have recently provided strong evidence that the basic independence assumption, which is used in most theoretical and applied economic models to assess the operation of markets, is rarely appropriate. These results, which clearly contradict closely held economic doctrines, have led some influential commentators to call for an entirely new economic paradigm to displace conventional neoclassical theory. This paper refutes the generality of these experimental findings by going to a well-functioning marketplace and examining more than 350 individual decisions across various incentive compatible elicitation mechanisms. The data suggest that individuals with significant marketlike experience behave largely in accordance with neoclassical predictions: any observed WTA/WTP disparity amongst this group can be explained by neoclassical arguments. In light of these findings, I believe that we have discarded neoclassical explanations of the value disparity too quickly. More narrowly, these empirical results have important implications for stated valuation methods, such as contingent valuation.

An active area of research within economics concerns the underpinnings of why people give to charitable causes. This study takes a new approach to this question by exploring motivations for giving among children aged 3-5. Using data gathered from 122 children, our artefactual field experiment naturally permits us to disentangle pure altruism and warm glow motivators for giving. We find evidence for the existence of pure altruism but not warm glow. Our results suggest pure altruism is a fundamental component of our preferences, and highlight that warm glow preferences found amongst adults likely develop over time. One speculative hypothesis is that warm glow preferences are learned through socialization.

There are many great ways to incorporate behavioral economics in a first-year undergraduate economics class-i.e., the course that is typically called "Principles of Economics." Our preferred approach integrates behavioral economics throughout the course (e.g., see Acemoglu, Laibson, and List 2015). With the integrated approach, behavioral content plays a role in many of the chapters of the principles of economics curriculum, including chapters on optimization, equilibrium, game theory, intertemporal choice, probability and risk, social preferences, household finance, the labor market, financial intermediation, monetary policy, economic fluctuations, and financial crises. We prefer the integrated approach because it enables the behavioral insights to show up where they are conceptually most relevant. By illustration, it is best to combine a discussion of downward nominal wage rigidity (i.e., the idea that workers strongly resist nominal wage declines) with the overall discussion of the labor market. Whether or not an instructor integrates behavioral economics throughout the principles of economics course, it makes sense to pull central materials together and dedicate a lecture (or more) to a focused discussion of behavioral economics. This note describes our approach to such a lecture, emphasizing six key principles of behavioral economics. Our choice of content for a behavioral lecture is motivated by three factors. First, we include ideas that are conceptually important. Second, we include material that is practically important and personally relevant to our students-we have found that such content resonates long after the course ends. Third, we include content that relates to what has been (or will be) taught in the rest of the course, and therefore serves as a complement. We want students to see that behavioral economics is an integrated part of economics, not a freak show that is isolated from "the standard ingredients" in the rest of the economics course. This paper summarizes our approach to such a focused behavioral lecture. In Section I, we define behavioral economics and place it in historical context. In Section II, we introduce six modular principles that can be used to teach behavioral economics. We provide PowerPoint notes on our home pages, which instructors should feel free to edit and use.

Evidence suggests that contributions to capital campaigns increase with the value of leadership gifts. We examine the response of subjects to the announcement of leadership gifts and its implied change in the campaign's target. The two effects are partitioned.

Time paths of carbon dioxide emissions in twenty-one industrial countries are examined from 1960-1997 to test for stochastic and conditional convergence. Both panel unit root tests and cross-section regressions are performed. Overall, we find significant evidence that CO2 emissions have converged.

We employ a two-step modified count data model to determine the county-level attributes that are conducive to attracting new foreign plants. Our estimation results indicate that previous counts of foreign direct investment, market size and accessibility, and land area are positively related to Foreign Direct Investment (FDI) occurrences; while higher input costs deter new foreign firm entry. Contrary to anecdotal evidence, our results suggest that stringent environmental regulations do not have a negative impact on FDI inflows. These findings have significant implications for policymakers, as flows of FDI are expected to increase dramatically given the economic integration of our global economy.

Labor force composition and the allocation of talent remain of vital import to modern economies. For their part, governments and companies around the globe have implemented equal employment opportunity (EEO) regulations to influence labor market flows. Even though such regulations are pervasive, surprisingly little is known about their impacts. We use a natural field experiment conducted across 10 U.S. cities to investigate if EEO statements in job advertisements affect the first step in the employment process, application rates. Making use of data from nearly 2,500 job seekers, we find considerable policy effects, but in an unexpected direction: the presence of an EEO statement dampens rather than encourages racial minorities willingness to apply for jobs. Importantly, the effects are particularly pronounced for educated job seekers and in cities with white majority populations. Complementary survey evidence suggests the underlying mechanism at work is "tokenism", revealing that EEO statements backfire because racial minorities avoid environments in which they are perceived as regulatory, or symbolic, hires rather than being hired on their own merits. Beyond their practical and theoretical importance, our results highlight how field experiments can significantly improve policy making. In this case, if one goal of EEO regulations is to enhance the pool of minority applicants, then it is not working.

We use a natural field experiment in which we hired over 2000 workers from an online labor market to explore how upfront payment affects worker motivation and misbehavior on the job. We start with a simple theory that shows paying upfront can increase misbehavior through reducing the perceived costs of cheating, but it can decrease misbehavior through generating a gift-exchange effect. Motivated by the theory, we designed a task that provided workers with opportunities to reciprocate or misbehave. A unique aspect of our design is that we are permitted an opportunity to measure the curvature of the gift-exchange value of the upfront payment. Our results suggest paying workers upfront induces a gift-exchange effect that is concave in the share of total wage paid upfront. Moreover, the impact is strong enough to suggest that small upfront payments are a cost-effective means for an employer to curb employee misbehavior.

This review summarizes results of field experiments examining individual behaviors across several market settings from - open-air markets to rideshare markets to tax-compliance markets - where people sort themselves into market roles wherein they make consequential decisions. Using three distinct examples from my own research on the endowment effect, left-digit bias, and omission bias, I showcase how field experiments can help researchers understand mediators, heterogeneity, and causal moderation involved in judgment biases in the field. In this manner, the review highlights that economic field experiments can serve an invaluable intellectual role alongside traditional laboratory research.

Once believed to be an impossibility, field experiments in economics now occupy a central place in the empiricist's quiver. In the past few decades alone field experiments have taken on much greater import in academe, across organizations, as well as for policymakers. But is this emergence simply a fad that will soon return field experiments to obscurity? I argue in this article that there is something fundamental about the emergence of field experiments, as controlling the assignment mechanism in the field provides unparalleled power to both understand the "effects of causes" and the "causes of effects." This knowledge generation then begins to uncover the generalizability and scalability of knowledge. Quite the opposite of a withering tool that will be gone tomorrow, I urge economists to "double down" on this comparative advantage and in doing so I provide four methodological paths which I hope will cement the promise and growth of field experiments in the social sciences.

Field experiments provide the clearest window into the true impact of many policies, allowing us to understand what works, what does not, and why. Yet, their widespread use has not been accompanied by a deep understanding of the political economy of their adoption in policy circles. This study begins with a large-scale natural field experiment that demonstrates the ineffectiveness of a widely implemented intervention. We leverage this result to understand how policymakers and a representative sample of the U.S. population update their beliefs of not only the policy itself, but the use of science and the trust they have in government. Policymakers, initially overly optimistic about the program's effectiveness, adjust their views based on evidence but show reduced demand for experimentation, suggesting experiment aversion when results defy expectations. Among the U.S. public, support for policy experiments is high and remains robust despite receiving disappointing results, though trust in the implementing institutions declines, particularly in terms of perceptions of competence and integrity. Providing additional information on the value of learning from unexpected findings partially mitigates this trust loss. These insights, from both the demand and supply side, reveal the complexities of managing policymakers' expectations and underscore the need to educate the public on the value of open-mindedness in policy experimentation.

To identify effective policies that can scale, a third option should be added to traditional A/B tests, that accounts for the realities of a programme implemented at scale. By flipping the traditional research and policy-development model, researchers can generate policy-based evidence to help policymakers scale the best policies.
