Around one million people are killed world wide every year in road-traffic accidents. The risks and consequences of accidents increase progressively with speed, which ultimately is determined by the individual driver. The behaviour of the motorist thus affects both her own and other peoples safety. Internalisation of external costs of road transport has hitherto been focused on distance-based taxes or insurance premiums. While these means, as they are designed today, may affect driven distance, they have no influence on driving behaviour. This paper argues that by linking on-board positioning systems to insurance premiums it is possible to reward careful driving and get drivers to self select into different risk categories depending on their compliance to speed limits. We report two economic field experiments that have tested ways to induce car-owners to have technical platforms installed in their vehicle in order to affect the extent of speeding. It is demonstrated that a bonus to remunerate those that have the device installed, tantamount to a lower insurance premium, increases drivers?propensity to accept the technical devices. In a second experiment the size of the bonus is made dependent on the actual frequency of speeding. We find that this is a second way to discipline users to drive at legal speeds.

I examine treatment effect heterogeneity within an experiment to inform external validity. The local average treatment effect (LATE) gives an average treatment effect for compliers. I bound and estimate average treatment effects for always takers and never takers by extending marginal treatment effect methods. I use these methods to separate selection from treatment effect heterogeneity, generalizing the comparison of OLS to LATE. Applying these methods to the Oregon Health Insurance Experiment, I find that the treatment effect of insurance on emergency room utilization decreases from always takers to compliers to never takers. Previous utilization explains a large share of the treatment effect heterogeneity. Extrapolations show that other expansions could increase or decrease utilization.

We explore the value of the strategy method to field experimentalists. Specifically, we demonstrate that, while the method may lead to reductions in subject understanding, it also generates valuable insights. We played the Third Party Punishment Game and the Generalized Trust Game with Ethiopian medical and nursing students applying the strategy method to the responding role in each case. Then, making use of two proxy measures for the students` cognitive abilities, we investigate the relationship between strategy-type choices and subject understanding. Thus, we find support for the assertion that apparently random and internally inconsistent strategies are symptomatic of problems of cognition. We also find support for the often, implicitly made assumption that, in BDM-type trust games, the ratio of what is returned to what is sent is an appropriate focus for comparative analyses of responder behaviour. Finally, we find evidence that an observed difference in third party punishing behaviour between Swiss and Ethiopian students is due, not to misunderstanding, but to variations in what is perceived as punishable. Our results lead us to conclude that the strategy method is of considerable value in Third Party Punishment Games, but need not be routinely applied in BDM-type trust games.

Inequity Aversion has long been applied in a game theoretic setting to explain that individuals are willing to sacrifice personal wealth in order to financially penalize players they perceive to be acting selfishly or unfairly. I apply inequity aversion to strategic mortgage default decisions and find that individual homeowners (as well as a second sample of professional mortgage lenders) have a differential stated willingness to walk away from their mortgage based on the perceived characteristics of their lender. Importantly, these significant differences can be removed even with extremely modest loan modifications. Finally, I document that regular homeowners and even professional lenders do a poor job differentiating between the owner of their loan and the servicer of their loan. This is particularly troubling given the extreme misconception of their bank's true character. As a result, much of their willingness to penalize is misplaced resulting in an unnecessary number of strategic mortgage defaults.

Why do people vote? We design a field experiment to estimate a model of voting 'because others will ask'. The expectation of being asked motivates turnout if individuals derive pride from telling others that they voted, or feel shame from admitting that they did not vote, provided that lying is costly. In a door-to-door survey about election turnout, we experimentally vary (i) the informational content and use of a flyer pre-announcing the survey, (ii) the duration and payment for the survey, and (iii) the incentives to lie about past voting. The experimental results indicate significant social image concerns. For the 2010 Congressional election, we estimate a value of voting 'to tell others' of about $15, contributing 2 percentage points to turnout. Lastly, we evaluate a get-out-the-vote intervention in which we tell potential voters that we will ask if they voted.

Information frictions play a central role in the formation of household inflation expectations, but there is no consensus about their origins. We address this question with novel evidence from survey experiments. We document two main findings. First, individuals in lower-inflation contexts have significantly weaker priors about the inflation rate. This finding suggests that rational inattention may be an important source of information frictions. Second, cognitive limitations also appear to be a source of information frictions: even when information about inflation statistics is made readily available, individuals still place a significant weight on less accurate sources of information, such as their memories of the price changes of the supermarket products they purchase. We discuss the implications of these findings for macroeconomic models and policy-making.

Policymakers are considering including stricter standards in international trade agreements. Using auctions to assess preferences, we find that the median consumer places no premium on fair trade foods produced under more stringent labor and environmental standards. This indicates that current trade policies may be preferable to U.S. consumers.

The robust laboratory evidence of preference reversal for lotteries has been interpreted as a threat to the general vailidity of standard theories of decision-making under uncertainty. This evidence is obtained from laboratory, that is, not real-world, lotteries with subjects who have not sought to make decisions among such lotteries. Here, the prevalence of preference reversal is studied in a field experiment with used cars, that is, a case of real-world non-trivial, non-lottery - but still payoff-uncertain - choice objects, and with subjects who registered as potential buyers of such cars. No sign of preference reversal was observed.

Microfinance has been heralded as an effective way to address imperfections in credit markets. But from a theoretical perspective, the success of microfinance contracts has puzzling elements. In particular, the group-based mechanisms often employed are vulnerable to free-riding and collusion, although they can also reduce moral hazard and improve selection. The authors created an experimental economics laboratory in a large urban market in Lima, Peru and over seven months conducted 11 different games that allow them to unpack microfinance mechanisms in a systematic way. They find that risk-taking broadly conforms to predicted patterns, but that behavior is safer than optimal. The results help to explain why pioneering microfinance institutions have been moving away from group-based contracts.

This study showcases the usefulness of field experiments to the study of environmental and resource economics. Our focus pertains to work related to field experiments in the area of 'behavioral' environmental and resource economics. Within this rubric, we discuss research in two areas: those that inform i) benefit cost analysis and ii) conservation of resources. Within each realm, we show how field experiments have been able to test the relevant theories, provide important parameters to construct new theories, and guide policymakers. We conclude with thoughts on how field experiments can be used to deepen our understanding of important areas within environmental and resource economics.

This paper describes a randomized field experiment testing the impact of a savings competition on the behavior of working homeless individuals at a transitional shelter. When monetary prizes were offered for achieving the highest saving rates within a particular month, average savings increased by $80 (a 30% increase) while income and attendance at case management meetings remained unchanged. However, repeating the competition in the following month had no effect because responsive savers selected out of the shelter after the first month. In summary, while competition can increase savings in the short run, its effect may be limited to the intensive margin and may diminish with repetition. Combined with our findings that the strongest determinant of savings is income, it appear that for transitional populations on the economic margin, policies that provide opportunities to increase income may be a more effective first step than saving incentives.

Field experiments represent a relatively new area in economics to understand the causal links from one variable to another. They have been used by academics to help answer interesting and policy-relevant questions in the developed world relating to educational attainment, tax avoidance, consumer finance, negative externalities, charitable giving, and labour market contracts. In this paper we bring together the key ideas behind the different variants of field experiments, how field experiments have been used to test theory, their limitations, and the new areas currently being opened up by field experiments.

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 paper, we developed and experimentally evaluated four novel educational programs delivered online: an informational brochure, a visual interactive tool, a written narrative, and a video narrative. The programs were designed to inform people about risk diversification, an essential concept for financial decision-making. The effectiveness of these programs was evaluated using the RAND American Life Panel. Participants were exposed to one of the programs, and then asked to answer questions measuring financial literacy and self-efficacy. All of the programs were found to be effective at increasing self-efficacy, and several improved financial literacy, providing new evidence for the value of programs designed to help individuals make financial decisions. The video was more effective at improving financial literacy scores than the written narrative, highlighting the power of online media in financial education.

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.

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.

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.
