Over the past three decades, the number of prison inmates has increased by more than 500 percent, leaving the United States the country with the highest incarceration rate in the world. With over two million individuals currently incarcerated, and over half a million prisoners released each year, the large and growing numbers of men being processed through the criminal justice system raises important questions about the consequences of this massive institutional intervention. This paper focuses on the consequences of incarceration for the employment outcomes of black and white job seekers. The manuscript is comprised of two studies: the first, a large-scale experimental audit of employers in Milwaukee, used matched pairs of young men to apply for real entry-level jobs to measure the extent to which employers use information about criminal histories and race to screen out otherwise qualified applicants. Indeed, the results of the audit study provide clear evidence for the dramatic impact of both a criminal record and race on employment opportunities: Ex-offenders are one-half to one-third as likely to receive initial consideration from employers relative to equivalent applicants without criminal records. Perhaps most striking, the results show that even blacks without a criminal record fare no better-and perhaps worse-than do whites with criminal records.The second study, a telephone survey of these same employers, gathered self-reported information about the considerations and concerns of employers in hiring entry-level workers, with a specific focus on employers' reactions to applicants with criminal backgrounds. By linking results from the audit study to those of the employer survey, I find that employers' self-reports vastly understate the barriers faced by both blacks and ex-offenders seeking entry-level employment. Though employer surveys can tell us a great deal of useful information about the relative preferences of employers, extreme caution should be used in generalizing these results to estimates of actual behavior. The findings of this project reveal an important, and much under-recognized, mechanism of stratification. A criminal record presents a major barrier to employment, with important implications for racial disparities.

In a randomized field experiment where first year university students could earn financial rewards for passing all first year requirements within one year we find small and non-significant average effects of financial incentives on the pass rate and the numbers of collected credit points. There is however evidence that high ability students collect significantly more credit points when assigned to (larger) reward groups. Low ability students collect less credit points when assigned to larger reward groups. After three years these effects have increased, suggesting dynamic spillovers. The small average effect in the population is therefore the sum of a positive effect for high ability students and a (partly) off-setting negative effect for low ability students. A negative effect of financial incentives for less able individuals is in line with research from psychology and recent economic laboratory experiments which shows that external rewards may be detrimental for intrinsic motivation.

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.

Behavioral economists have recently put forth a theoretical explanation for the equity premium puzzle based on combining myopia and loss aversion. Complementing the behavioral theory is evidence from laboratory experiments, which provide strong empirical support consistent with myopic loss aversion (MLA). Yet, whether, and to what extent, such preferences underlie behaviors of traders in their natural domain remains unknown. Indeed, a necessary condition for the MLA theory to explain the equity premium puzzle is for marginal traders in markets to exhibit such preferences. Using minute-by-minute trading observations from over 864,000 price realizations in a natural field experiment, we find data patterns consonant with MLA: in their normal course of business, professional traders who receive infrequent price information invest 33% more in risky assets, yielding profits that are 53% higher, compared to traders who receive frequent price information. Beyond testing theory, these results have important implications for efficient resource allocation as well as characterizing the optimal structure of social and economic policies.

A commonly held view is that laboratory experiments provide researchers with more "control" than natural field experiments, and that this advantage is to be balanced against the disadvantage that laboratory experiments are less generalizable. This paper presents a simple model that explores circumstances under which natural field experiments provide researchers with more control than laboratory experiments afford. This stems from the covertness of natural field experiments: laboratory experiments provide researchers with a high degree of control in the environment which participants agree to be experimental subjects. When participants systematically opt out of laboratory experiments, the researcher's ability to manipulate certain variables is limited. In contrast, natural field experiments bypass the participation decision altogether and allow for a potentially more diverse participant pool within the market of interest. We show one particular case where such selection is invaluable: when treatment effects interact with participant characteristics.

Prior to the November 7, 2000 election, randomized voter mobilization experiments were conducted in the vicinity of college campuses in New York State, Colorado, and Oregon. Lists of registered people under the age of 30 were randomly assigned to treatment and control groups. A few days before Election Day, the treatment group received a phone call or face-to-face contact from Youth Vote 2000, a nonpartisan coalition of student and community organizations, encouraging them to vote.

The growth of the "gig" economy generates worker flexibility that, some have speculated, will favor women. We explore one facet of the gig economy by examining labor supply choices and earnings among more than a million rideshare drivers on Uber in the U.S. Perhaps most surprisingly, we find that there is a roughly 7% gender earnings gap among drivers. The uniqueness of our data - knowing exactly the production and compensation functions - permits us to completely unpack the underlying determinants of the gender earnings gap. We find that the entire gender gap is caused by three factors: experience on the platform (learning-by-doing), preferences over where/when to work, and preferences for driving speed. This suggests that, as the gig economy grows and brings more flexibility in employment, women's relatively high opportunity cost of non-paid-work time and gender-based preference differences can perpetuate a gender earnings gap even in the absence of discrimination.

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.

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.

The rising childhood obesity rate calls for interventions aimed at improving child food choice, and one recent innovation is the use of behavioral 'nudges.' We conducted a field experiment with over 1,400 children to measure the impact of interventions based on two behavioral theories: reciprocity and theories of self-control. The interventions were implemented in the classroom prior to observing choices between a healthy and less healthy milk choice in the cafeteria. We found that small, unconditional gifts (triggering reciprocity) increased the choice of the healthier milk by 15 percentage points relative to a control group. Giving the option to set a goal (an internal commitment device) was most effective for the younger children and increased the choice of the healthier milk by 10 percentage points. About two thirds of children made a goal to select the healthier milk, and almost 90 percent followed through with their goal. We also see an impact of health information delivered by teachers. Our results have implications for policy and practice, since low cost interventions implemented at school may have an impact on what kids choose to eat and in turn on obesity rates.

Overloaded electrical systems are a major source of unreliable power (outages) in developing countries. Using a randomized saturation design, we estimate the impact of energy efficient lightbulbs on household electricity consumption and local electricity reliability. Receiving compact fluorescent lightbulbs (CFLs) significantly reduced household electricity consumption. Estimates not controlling for spillovers in take-up underestimate the impacts of the CFLs, as control households near the treated are likely to take-up CFLs themselves. Greater saturation of CFLs within a transformer leads to aggregate reliability impacts of two fewer days per month without electricity due to unplanned outages relative to pure controls. Increased electricity reliability permits households to consume more electricity services, suggesting that CFL treatment results in technological externalities. The spillovers in take-up and technological externalities that we document may provide an additional explanation for the gap between empirical and engineering estimates of the impacts of energy efficient technologies.

In order to test the proposition that performance in bargaining experiments is significantly affected by degree of monetarization, market integration, and relative westernization, a one-shot Ultimatum Game was conducted during the months of June and July 1998 in two villages in a rural region of Papua New Guinea: Anguganak (where the people speak Au) and Bogasip (where they speak Gnau). Although the villages are located in close proximity to one another and are relatively homogeneous culturally, and both subsist using a mixture of foraging and horticulture and have an elaborate system of exchange relationships, they are distinguished by their average degree of exposure to and integration in a cash-based economy, as well as their degree of education (both are greater in Anguganak). The different sections of the chapter provide: an ethnographic account of the two villages; a description of the experimental methods employed; a presentation and analysis of the results in terms of various indicators of wealth and market integration; and a discussion of the implications of the results. The level of offers made in the Ultimatum Game data combined for Anguganak and Bogasip were between those in western industrialized populations and the Machiguenga of Peru. There was some indication that variability in the level of market integration between the two village populations may have influenced the results, although they appeared to be equally influenced by local beliefs on reciprocity, generosity, and indebtedness, and an unfamiliarity with impersonal transactions.

Acts of dishonesty permeate life. Understanding their origins, and what mechanisms help to attenuate such acts is an under explored area of research. This study takes an economics approach to explore the propensity of individuals to act dishonestly across different economic environments. We begin by developing a simple model that highlights the channels through which one can increase or decrease dishonest acts. We lend empirical insights into this model by using an experiment that includes both parents and their young children as subjects. We find that the highest level of dishonesty occurs in settings where the parent acts alone and the dishonest act benefits the child rather than the parent. In this spirit, there is also an interesting effect of children on parents' behavior: in the child's presence, parents act more honestly, but there are gender differences. Parents act more dishonestly in front of sons than daughters. This finding has the potential of shedding light on the origins of the widely documented gender differences in cheating behavior observed among adults.

This paper discusses why running experiments in the field, outside of the university lab, can help us enrich the analysis we do of experimental data. One of the main arguments of the paper is that people participating in experiments, including students, do not come naked to the lab. They bring a great deal of rules of thumb, heuristics, values, prejudices, expectations and knowledge about the others participating, and about similar games, and use such information to make their decisions. The paper offers a short mention of relevant field experiments, and a more detailed look at field experiments conducted by the author, including a data set of CPR experiments run in 10 villages, between 2000 and 2002, with more than 1300 villagers in about 220 sessions, and replications with about 250 university students in more than 40 sessions. It offers then main lessons from bringing the lab to the field. Also there is a discussion of additional information gathered through different field instruments as well as community workshops with the participants to discuss the experimental data, the external validity of the experiments and their results, through parallels with their daily life. One of the lessons is that the greater variance in certain demographics about the experimental subjects might help explain variations in lab behavior that cannot be fully explained by the experimental institutions we study. Also, certain significant differences in behavior between villagers and students will be discussed.

This paper studies the impact of reservation for women on the performance of policy makers and on voters' perceptions of this performance. Since the mid 1990's, one third of Village Council head positions in India have been randomly reserved for a woman: In these councils only women could be elected to the position of chief. Village Councils are responsible for the provision of many local public goods in rural areas. Using a data set which combines individual level data on satisfaction with public services with independent assessments of the quality of public facilities, we compare objective measures of the quantity and quality of public goods, and information about how villagers evaluate the performance of male and female leaders. Overall, villages reserved for women leaders have more public goods, and the measured quality of these goods is at least as high as in non-reserved villages. Moreover, villagers are less likely to pay bribes in villages reserved for women. Yet, residents of villages headed by women are less satisfied with the public goods, including goods that are beyond the jurisdiction of the Panchayat. This may help explain why women rarely win elections even though they appear to be at least as effective leaders along observable dimensions, and are less corrupt.

The gender difference in competitiveness has been cited as an important factor driving the gender gap in labor market outcomes. Using a natural field experiment with 35,000 university students, I explore the impact of compensation scheme on willingness to apply for a job. I find that competitive compensation schemes disproportionately deter women from applying, which cannot be explained by differences in risk preferences alone. I also vary whether the job is introduced as helping a non-profit, which increases application rates, suggesting a role for social preferences in application decisions. Finally, I observe a correlation between competitiveness preferences and career choice.

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 existing literature on socially responsible purchasing relies heavily on stated preference measures elicited through surveys that utilize hypothetical market choices. This paper explores consumers' revealed purchasing behavior with regard to fair trade coffee and is apparently the first to do so in an actual market setting. In a series of experiments, we investigated differences in consumer responsiveness to relative price changes in fair trade and non-fair trade brewed coffees. In order to minimize the hypothetical bias that may be present in some experimental settings, we conducted our experiments in cooperation with a vendor who allowed us to vary prices in an actual coffee shop. Using a choice model, we found that purchasers of fair trade coffee were much less price responsive than those of other coffee products. The demonstration of low sensitivity to price suggests that the market premiums identified by stated preference studies do indeed exist and are not merely artifacts of hypothetical settings.
