We overview the use of field experiments in labor economics. We showcase studies that highlight the central advantages of this methodology, which include: (i) using economic theory to design the null and alternative hypotheses; (ii) engineering exogenous variation in real world economic environments to establish causal relations and learning about the underlying mechanisms; and (iii) engaging in primary data collection and often working closely with practitioners. To highlight the potential for field experiments to inform issues in labor economics, we organize our discussion around the individual life cycle. We therefore consider field experiments related to the accumulation of human capital, the demand and supply of labor, behavior within firms, and close with a brief discussion of the nascent literature of field experiments related to household decision-making.

An important dialogue between theorists and experimentalists over the past few decades has raised the study of the interaction of psychological and economic incentives from academic curiosity to a bona fide academic field. One recent area of study within this genre that has sparked interest and debate revolves around the "hidden costs" of conditional incentives. This study overlays randomization on a naturally-occurring environment in a series of temporally-linked field experiments to advance our understanding of the economics of charity and test if such "costs" exist in the field. This approach permits us to examine why people initially give to charities, and what factors keep them committed to the cause. Several key findings emerge. First, there are hidden benefits of conditional incentives that would have gone undetected had we maintained a static theory and an experimental design that focused on short run substitution effects rather than dynamic interactions. Second, we can reject the pure altruism model of giving. Third, we find that public good provision is maximized in both the short and long run by using conditional, rather than unconditional, incentives.

We organize regular business meetings for randomly selected managers of young Chinese firms to study the effect of business networks on firm performance. We randomize 2,800 managers into several groups that hold monthly meetings for one year, and a "no-meetings" control group. We find that: (1) The meetings increase firm revenue by 7.8 percentage points, and also significantly increase profit, a management score, employment, and the number of business partners; (2) These effects persist one year after the conclusion of the meetings; and (3) Firms randomized to have better peers exhibit higher growth. We exploit additional interventions to document concrete channels: (4) Peers share exogenous business-relevant information, particularly when they are not competitors, showing that the meetings facilitate learning; (5) Managers create more business partnerships in the regular than in other one-time meetings, showing that the meetings improve firm-to-firm matching.

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.

This article reports the results of several field experiments designed to measure campaign effects in partisan contests. The findings suggest incumbent campaigns failed to increase incumbent vote share, whereas the challenger campaign was effective. To understand these and other results, the incumbent's optimal spending strategy was analyzed theoretically. The analysis reveals that if incumbents maximize their probability of victory rather than vote share, campaigns by typical incumbents are expected to produce only minimal improvement in incumbent vote share. The analysis also explains how returns to campaign spending vary with the competitiveness of the election, how incumbent spending can improve the incumbent's probability of victory yet have only minimal effect on incumbent vote share, and why rational spending plans might decrease the sponsor's expected vote. This article demonstrates the wide scope of application for field experiments and provides an example of how experimental findings can serve as a catalyst for generating theories.

Devolution of tasks to local levels of government has recently become a popular agenda item within certain political factions in the US. While one expects the local policymaker to tailor policies to match the preferences of his constituents, critics of local policymaking claim that externalities are ignored and inefficiencies thus arise under local control of certain policies. A primary example concerns the control of pollution, which is known to have adverse effects on neighbouring jurisdictions. Whether localities actually 'race to the bottom' and enact lax environmental policies when given the chance remains an open issue. In this study, we make use of stochastic dominance tests to examine if President Reagan's policy of 'New Federalism' in the early 1980s induced states to lower environmental standards. Among the several environmental measures analysed, we do not find any evidence that the 'race to the bottom' materialized. Indeed, the evidence shows that even during these lean years of federal intervention several indicators of environmental quality at the state level continued to improve.

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.

Evidence suggests the calibration of hypothetical and actual behavior is good-specific. We examine whether clustering commodities into mutual categories can reduce the burden. While we reject a common calibration across sets of commodities, a sport-specific calibration function cannot be rejected.

In this paper we explore to what extent secondary policy issues are influenced by electoral incentives. We develop a political agency model in which a politician decides on both a frontline policy issue, such as the level of public spending, and a secondary policy issue, such as environmental policy. The model shows under which conditions the incumbent finds it worthwhile to manipulate the secondary policy to attract additional votes to his platform. We test the predictions of the model using state-level panel data on Gubernatorial environmental policy choices over the years 1960-2000. In contrast to the popular view that choices on secondary policy instruments are largely determined by lobbying, we find strong effects of electoral incentives on environmental policy.

Little is known about the effect of message framing on conservation behavior over time. In a randomized controlled trial with residential households, we use advanced metering and information technologies to test how different messages about household energy use impact the dynamics of conservation behavior down to the appliance level. Our results, based on 374 million panel observations of kilowatt-hour (kWh) electricity consumption for 118 households over 9 months, show that differences in behavioral responses due to message framing become more significant over time. We find that a health-based frame, in which households consider the human health effects of their marginal electricity use, induced persistent energy savings behavior of 8-10% over 100 days; whereas a more traditional cost savings frame, drove sharp attenuation of treatment effects after 2 weeks with no significant savings versus control after 7 weeks. We discuss the implications for the design of effective information campaigns to engage households in conservation behavior.

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.

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.

Colombia's PACES program provided over 125,000 poor children with vouchers that covered half the cost of private secondary school. The vouchers were renewable annually conditional on adequate academic progress. Since many vouchers were assigned by lottery, program effects can reliably be assessed by comparing lottery winners and losers. Estimates using administrative records suggest the PACES program increased secondary school completion rates by 15-20 percent. Correcting for the greater percentage of lottery winners taking college admissions tests, the program increased test scores by two-tenths of a standard deviation in the distribution of potential test scores. Boys, who have lower scores than girls in this population, show larger test score gains, especially in math.

Every new method of trade offers an opportunity for economic agents to compare its costs and benefits relative to the status quo. Such comparison motivates sorting across market segments and reshapes the whole marketplace. The Internet provides an excellent example: it introduces substantial search cost savings over brick and mortar retail stores but imposes new obstacles for sellers to convey quality. Using sports card trading as a case study, we provide empirical evidence on (1) the sorting of product quality between the online and offline segments, (2) the changes for retail outlets after the Internet came into place, and (3) how supporting industries such as professional grading and card manufacturing adapted to take advantage of the new market.

Almost a third of US children ages 2-19 are deemed overweight or obese, and part of the problem is the habitual decision to consume high calorie, low nutrient foods. We propose that the school lunchroom provides a 'teachable moment' to engage children in making healthful choices. We conduct a field experiment with over 1,500 participants in grades K-8 and evaluate the impact of small non-monetary incentives on the selection of milk in the school lunchroom. At baseline, only 16% of children select white milk relative to 84% choosing chocolate milk. We find a significant effect of incentives, which increase white milk selection by 2.5 times, to 40%. One concern with incentives is that they may decrease intrinsic motivation to eat healthy, called 'crowd-out of intrinsic motivation.' However, we do not find evidence of 'crowd-out'; rather, we see some suggestive evidence of the positive habit forming effect of incentives.

The use of experimental settings to observe human behaviour in a controlled environment of incentives, rules and institutions, has been widely used by the behavioural sciences for some time now, particularly by psychology and economics. In most cases the subjects are college students recruited from one to two hour decision making exercises in which, depending on their choices, they earn cash averaging US$ 20. In such exercises players face a set of feasible actions, rules and incentives (payoffs) involving different forms of social exchange with other people, and that in most cases involve some kind of externalities with incomplete contracts, such as in the case of common-pool resources situations. Depending on the ecological and institutional settings, the resource users face a set of feasible levels of extraction, a set of rules regarding the control or monitoring of individual use, and sometimes ways of imposing material or non-material costs or rewards to those breaking or following the rules. We brought the experimental lab to the field and invited about two hundred users of natural resources in three Columbian rural villages to participate in such decision making exercises and through these and other research instruments we learned about the ways they solve - or fail to - tragedies of the commons with different social institutions. Further, bringing the lab to the field allowed us to explore some of the limitations of existing models about human behavior and its consequences for designing policies for conserving ecosystems and improving social welfare.

Framing a decision situation differently has affected behavior substantially in previous studies. This paper tests a framing effect in a field experiment at the University of Zurich. Each semester, every student has to decide whether to contribute to two social funds. Students were randomly informed that a high percentage of the student population contributed (or, equivalently, that a low percentage did not contribute), while others received the information that a relatively low percentage contributed (or a high percentage did not contribute). The results show the influence of framing effects is limited. People behave in a conditional cooperative way if informed either about the number of contributors or about the equivalent number of non-contributors. The positive correlation between group behavior and individual behavior is, however, weaker when the focus is on the defectors. The field experiment also shows gender differences in social comparison.
