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.

Clear Skies is an economist's approach to pollution reduction. We heartily endorse its core approach, while recommending surgery for a few minor blemishes.

How does setting a donation option as the default in a charitable appeal affect people's decisions? In eight studies, comprising 11,508 participants making 2,423 donation decisions in both experimental settings and a large scale-natural field experiment, we investigate the effect of "choice-option" defaults on the donation rate, average donation amount, and the resulting revenue. We find (1) a "lower-bar" effect, where defaulting a low amount increases donation rate, (2) a "scale-back" effect where low defaults reduce average donation amounts and (3) a "default-distraction' effect, where introducing any defaults reduces the effect of other cues, such as positive charity information. Contrary to the view that setting defaults will backfire, defaults increased revenue in our field study. However, our findings suggest that defaults can sometimes be a "self-cancelling" intervention, with countervailing effects of default option magnitude on decisions and resulting in no net effect on revenue. We discuss the implications of our findings for research on fundraising specifically, for choice architecture and behavioral interventions more generally, as well as for the use of "nudges" in policy decisions.

One conjecture in the theory of incentives is that incentives based on broader outcomes may be better at motivating agents than incentives based on narrow measures. We designed an experiment to test these hypotheses using a "prospective randomized evaluation procedure" (PREP). We then apply PREP to training programs as typically funded by donors of economic development assistance. We randomly assigned 274 participating entrepreneurs in the Philippines to one of 26, simultaneous, one-day, training classes in marketing. Trainers were given cash incentives based on the average score of their "students" on a standardized test containing an alternative number of questions, which were randomly assigned to each class. We then examined outcomes based on student satisfaction ratings of the trainer. Our results suggest that incentives based on broad outcomes are more effective than incentives based on narrow outcomes. We conclude with ways to improve our approach as well as with a discussion of the implications for using prospective randomized evaluation for improving the evaluation of donor projects.

Using a field experiment, we investigate whether, and if so, how spam is targeted. By comparing the spam rates among a set of synthetic email accounts, we find that spam is targeted to clients of particular email providers, users who declared interest in particular products or services, and consumer segments that are relatively more likely to make online purchases.

Intestinal helminths - including hookworm, roundworm, schistosomiasis, and whipworm - infect more than one-quarter of the world's population. A randomized evaluation of a project in Kenya suggests that school-based mass treatment with deworming drugs reduced school absenteeism in treatment schools by one quarter; gains are especially large among the youngest children. Deworming is found to be cheaper than alternative ways of boosting school participation. By reducing disease transmission, deworming creates substantial externality health and school participation benefits among untreated children in the treatment schools and among children in neighboring schools. These externalities are large enough to justify fully subsidizing treatment. We do not find evidence that deworming improves academic test scores. Existing experimental studies, in which treatment is randomized among individuals in the same school, find small and insignificant deworming treatment effects on education; however, these studies underestimate true treatment effects if deworming creates positive externalities for the control group and reduces treatment group attrition.

This study examines social preferences in three distinct field environments. In the first field setting, I allow consumers of all age and education levels to participate in one-shot and multiple-shot public goods games in a well-functioning marketplace. The second field study, an actual university capital campaign, gathers data from mail solicitations sent to 2,000 Central Florida residents. In the third field experiment, I examine data from an uncontrolled environment, a television gameshow, which closely resembles the classic prisoner's dilemma game. Several insights emerge; perhaps the most provocative is that age and social preferences appear linked.
