Field experiments are a useful empirical tool that can be deployed in any sub-discipline - including institutional economics - to enhance the sub-discipline's empirical insights. However, we here argue that there exist fundamental barriers to the use of field experiments in understanding the impact of institutions on economic growth. Despite these obstacles, we present some significant scholarly contributions that merit exposition, while also proposing some future methods for using field experiments within institutional economics. While field experiments may be limited in answering questions in institutional economics with macroeconomic outcomes, there is great potential in employing field experiments to answer micro founded questions.

Will college students who set goals for themselves work harder and achieve better outcomes? In theory, setting goals can help present-biased students to mitigate their self-control problem. In practice, there is little credible evidence on the causal effects on goal setting for college students. We report the result of two field experiments that involved almost four thousand college students in total. One experiments asked treated students to set goals for performance in the course; the other asked treated students to set goals for a particular task (completing online practice exams). Task-based goals had robust positive effects on the level of task completion, and task-based goals also increased course performance. We also find that performance-based goals had positive but small effects on course performance. We use a theoretical framework that builds on present bias and loss aversion to interpret our results. Since task-based goal setting is low-cost, scalable and logistically simple, we conclude that our findings have important implications for educational practice and future research.

This study investigates how to use regression adjustment to reduce variance in experimental data. We show that the estimators recommended in the literature satisfy an orthogonality property with respect to the parameters of the adjustment. This observation greatly simplifies the derivation of the asymptotic variance of these estimators and allows us to solve for the efficient regression adjustment in a large class of adjustments. Our efficiency results generalize a number of previous results known in the literature. We then discuss how this efficient regression adjustment can be feasibly implemented. We show the practical relevance of our theory in two ways. First, we use our efficiency results to improve common practices currently employed in field experiments. Second, we show how our theory allows researchers to robustly incorporate machine learning techniques into their experimental estimators to minimize variance.

We use structural estimates of time preferences to customize incentives for a sample of polio vaccinators during a series of door-to-door vaccination drives in Pakistan. Our investigation proceeds in three stages. First, we measure time preferences using intertemporal allocations of vaccinations. Second, we derive the mapping between these structural estimates and individually optimal incentives given a specific policy objective. Third, we experimentally evaluate the effect of matching contract terms to individual discounting patterns in a subsequent experiment with the same vaccinators. This exercise provides a test of the specific point predictions given by structural estimates of time preference. We document present bias among vaccinators and find that tailored contracts achieve the intended policy objective of smoothing intertemporal allocations of effort.

We use a field experiment to study how workers value alternative work arrangements. During the application process to staff a national call center we randomly offered applicants choices between traditional M-F 9am - 5pm office positions and alternatives. These alternatives include flexible scheduling, working from home, and positions that give the employer discretion over scheduling. We randomlyvaried the wage difference between the traditional option and the alternative, allowing us to estimate the entire distribution of willingness to pay (WTP) for these alternatives. We validate our results using a nationally-representative survey. The great majority of workers are not willing to pay for flexible scheduling relative to a traditional schedule: either the ability to choose the days and times of work or the number of hours they work. However, the average worker is willing to give up 20% of wages to avoid a schedule set by an employer on a week's notice. This largely represents workers' aversion to evening and weekend work, not scheduling unpredictability. Traditional M-F 9am - 5pm schedules are preferred by most jobseekers. Despite the fact that the average worker isn't willing to pay for scheduling flexibility, a tail of workers with high WTP allows for sizable compensating differentials. Of the workerfriendly options we test, workers are willing to pay the most (8% of wages) for the option of working from home. Women, particularly those with young children, have higher WTP for work from home and to avoid employer scheduling discretion. They are slightly more likely to be in jobs with these amenities, but the differences are not large enough to explain any wage gaps.

Despite having the same probability of being drawn, certain number combinations are more popular than others among the lottery players. One explanation of such preferences is the representativeness heuristic (RH). Unlike previous hypothetical experiments, in the present experiment we used real-life lottery tickets, involving a high payout in case of winning to elicit true preferences. To verify if people prefer randomly-looking number combinations, participants were to choose a preferred ticket. To validate if it is likely to be caused by RH, we correlated preference for "random" sequences with the belief in dependence between subsequent coin tosses. We confirm that people strongly prefer random sequences and that a non-trivial fraction believes in dependence between coin tosses. However, there is no correlation between these two tendencies, questioning the RH explanation. By contrast, participants who have an (irrationally) strong preference for number combinations also tend to make (irrationally) specific predictions in the coin task. Unexpectedly, we find that females are considerably more likely to belong to this groups than males.

Habit is a frequently mentioned but understudied cause of political action. This article provides the first direct test of the hypothesis that casting a ballot in one election increases one's propensity to go to the polls in the future. A field experiment involving 25,200 registered voters was conducted prior to the November general election of 1998. Subjects were randomly assigned to treatment conditions in which they were urged to vote through direct mail or face-to-face canvassing. Compared to a control group that received no contact, the treatment groups were significantly more likely to vote in 1998. The treatment groups were also significantly more likely to vote in local elections held in November of 1999. After deriving a statistical estimator to isolate the effect of habit, we find that, ceteris paribus, voting in one election substantially increases the likelihood of voting in the future. Indeed, the influence of past voting exceeds the effects of age and education reported in previous studies.

Colombia's PACES program provided over 125,000 pupils from poor neighborhoods with vouchers that covered approximately half the cost of private secondary school. Since many vouchers were allocated by lottery, we use differences in outcomes between lottery winners and losers to assess program effects. Three years into the program, lottery winners were 15 percentage points more likely to have attended private school, had completed .1 more years of schooling, and were about 10 percentage points more likely to have finished 8 th grade, primarily because they were less likely to repeat grades. The program did not significantly affect dropout rates. Lottery winners scored .2 standard deviations higher on standardized tests. There is some evidence that winners worked less than losers and were less likely to marry or cohabit as teenagers. On average, lottery winners increased their educational expenditure by about 70% of the value of the voucher. Since winners also worked less, they devoted more total resources to education. Compared to an equivalent expansion of the public education system, the voucher program increased annual government educational expenditure by about $24 per winner. But the costs to the government and to participants were probably much less than the increase in winners' earnings due to greater educational attainment.

Workplace misbehaviors are often governed by explicit monitoring and strict punishment. Such enforcement activities can serve to lessen worker productivity and harm worker morale. We take a different approach to curbing worker misbehavior-bonuses. Examining more than 6500 donor phone calls across more than 80 workers, we use a natural field experiment to investigate how different wage contracts influence workers' propensity to break workplace rules in harmful ways. Our findings show that even though standard relative performance pay contracts, relative to a fixed wage scheme, increase productivity, they have a dark side: they cause considerable cheating and sabotage of co-workers. Yet, even in such environments, by including an unexpected bonus, the employer can substantially curb worker misbehavior. In this manner, our findings reveal how employers can effectively leverage bonuses to eliminate undesired behaviors induced by performance pay contracts.

This paper reports a field experiment involving manipulation of invitations to register in an experimental economics subject database. Two types of invitations were sent out: one emphasizing pecuniary and the other non-pecuniary benefits of participation. The former resulted in higher response rate and the strength of this treatment effect was comparable in different groups defined by gender and academic major. In a follow-up test conducted about a year later it was found that individuals recruited by invitations emphasizing monetary benefits were less willing to make an effort to participate in a non-paid survey. The very same survey also showed that they were marginally less altruistic in general.

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.

In this study, we first present a large natural field experiment that tested messages aimed at increasing tax compliance. We find that the main drivers of changes in compliance are messages describing the monitoring and enforcement behavior of the tax collector. A second natural field experiment built on the results of the first experiment to further investigate what kinds of costs resulting from tax collector oversight are salient to taxpayers. Specific time and cognitive incentives did not significantly increase payment rates, whereas stating non-specific costs of inaction did. Additional analyses suggest the increase in compliance is likely due to a 'fill in the blank' effect in which taxpayers assume the consequence is a fine. Interestingly, specifically stating maximum fine or jailtime consequences have the largest effect in a laboratory setting but only if the consequences are interpreted as realistic. Overall, our study reinforces that tax authorities can use short messages to increase tax compliance; the estimated accelerated revenue from the two field studies amounts to 9.9m GBP.

Numerous laboratory studies find that minor nuances of presentation and description change behavior in ways that are inconsistent with standard economic models. How much do these context effect matter in natural settings, when consumers make large, real decisions and have the opportunity to learn from experience? We report on a field experiment designed to address this question. A South African lender sent letters offering incumbent clients large, short-term loans at randomly chosen interest rates. The letters also contained independently randomized psychological "features" that were motivated by specific types of frames and cues shown to be powerful in the lab, but which, from a normative perspective, ought to have no impact. Consistent with standard economics, the interest rate significantly affected loan take-up. Inconsistent with standard economics, some of the psychological features also significantly affected take-up. The average effect of a psychological manipulation was equivalent to a one half percentage point change in the monthly interest rate. Interestingly, the psychological features appear to have greater impact in the context of less advantageous offers and persist across different income and education levels. In short, even in a market setting with large stakes and experienced customers, subtle psychological features appear to be powerful drivers of behavior. The findings pose a challenge for the social sciences: they suggest that psychological nuance matters but may be inherently difficult to predict given the impact of context. Successful incorporation of psychological features into field studies is likely to prove a vital, but nontrivial, addition to the formation of more general theories on when, why, and how frames and cues influence important decisions.

Monetary incentives are widely used to align employees' actions with the objectives of employers. We conduct a field experiment in a retail chain to evaluate whether an attendance bonus reduces employee absenteeism. The RCT assigned 346 apprentices for one year to either a monetary attendance bonus, a time-off bonus or a control group. We find that neither form of the bonus reduced absenteeism, but the monetary bonus increased absence by around 45%. This backfiring effect is persistent and driven by the most recently hired apprentices. Survey results reveal that the bonus shifted the perception of absenteeism as acceptable behavior.

Corporate Social Responsibility (CSR) has become a cornerstone of modern business practice, developing from a "why" in the 1960s to a "must" today. Early empirical evidence on both the demand and supply sides has largely confirmed CSR's efficacy. This paper combines theory with a large-scale natural field experiment to connect CSR to an important but often neglected behavior: employee misconduct and shirking. Through employing more than 3,000 workers, we find that our usage of CSR increases employee misbehavior - 20% more employees act detrimentally toward our firm by shirking on their primary job duty when we introduce CSR. Complementary treatments suggest that "moral licensing" is at work, in that the "doing good" nature of CSR induces workers to misbehave on another dimension that hurts the firm. In this way, our data highlight a potential dark cloud of CSR, and serve to forewarn that such business practices should not be blindly applied.
