Survey research finds that mothers suffer a substantial wage penalty, although the causal mechanism producing it remains elusive. The authors employed a laboratory experiment to evaluate the hypothesis that status-based discrimination plays an important role and an audit study of actual employers to assess its real-world implications. In both studies, participants evaluated application materials for a pair of same-gender equally qualified job candidates who differed on parental status. The laboratory experiment found that mothers were penalized on a host of measures, including perceived competence and recommended starting salary. Men were not penalized for, and sometimes benefited from, being a parent. The audit study showed that actual employers discriminate against mothers, but not against fathers.

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.

We present results from a field experiment testing the gift-exchange hypothesis inside a tree-planting firm paying its workforce incentive contracts. Firm managers told a crew of tree planters they would receive a pay raise for one day as a result of a surplus not attribuable to past planting productivity. We compare planter productivity - the number of trees planted per day - on the day the gift was handed out with productivity on previous and subsequent days of planting on the same block, and thus under similar planting conditions. We find direct evidence that the gift had a significant and positive effect on daily planter productivity, controlling for planter-fixed effects, weather conditions and other random daily shocks. Moreover, reciprocity is the strongest when the relationship between planters and the firm is long term.

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.

Can globalization change our willingness to redistribute to the poor? We propose the hypothesis that in developing countries, the 'glitter' of foreign direct investment (FDI) reduces public support for redistribution by creating perceptions of better employment opportunities for the poor. Initial evidence is derived from World Value Survey responses from developing economies. Delving deeper, a framed field experiment in India reveals foreign ownership of low-skilled firms reduces redistribution to the poor. We further find that rich conservatives drive this reduction. This analysis provides the first experimental evidence of the causal impact of globalization on redistribution, mediated by ideology and income.

The National School Lunch Program (NSLP) is a federal food assistance program that serves over 30 million children in the United States annually. Yet the impact of NSLP on nutritional intake may be limited because children frequently do not choose the healthier offerings or waste large portions of their meal. In this article, we study whether we can improve the impact of the NSLP on child food choice through low-cost nudges. We conduct a field experiment in a school lunchroom with 2500 children, evaluating the impact of informational prompts on milk choice and consumption over two weeks. We find that the prompts alone increase the proportion of children choosing and consuming the healthier white milk relative to sugar-sweetened chocolate milk from 20% in the control group to 30% in the treatment groups. Adding health or taste messaging to the prompt does not seem to make a difference. We survey students and find that most prompts affect perceived healthfulness of the milk, but not perceived taste. Finally, we find that the prompts are nearly as effective as a small nonmonetary incentive.

Group liability is often portrayed as the key innovation that led to the explosion of the microcredit movement, which started with the Grameen Bank in the 1970s and continues on today with hundreds of institutions around the world. Group lending claims to improve repayment rates and lower transaction costs when lending to the poor by providing incentives for peers to screen, monitor and enforce each other's loans. However, some argue that group liability creates excessive pressure and discourages good clients from borrowing, jeopardizing both growth and sustainability. Therefore, it remains unclear whether group liability improves the lender's overall profitability and the poor's access to financial markets. We worked with a bank in the Philippines to conduct a field experiment to examine these issues. We randomly assigned half of the 169 pre-existing group liability centers of approximately twenty women to individual-liability centers (treatment) and kept the other half as-is with group liability (control). We find that the conversion to individual liability does not affect the repayment rate, and leads to higher growth in center size by attracting new clients.

This paper evaluates a program in Kenya that encourages the production of export oriented crops by providing smallholder farmers with credit linked to agricultural extension and marketing services. We use an experimental design in which farmer selfhelp groups are randomly assigned to either a control group, a group receiving all DrumNet services, or a group receiving all services except credit. Among the services offered by DrumNet, credit is the most important. Since the production of export crops requires a significant investment in capital and inputs, without credit farmers are less likely to plant the mentioned crops. Overall, the results show that DrumNet is an effective model for encouraging the production of export oriented crops.

We use data from a promotion campaign of NH-Hoteles to study self-selection of participants in a gift-exchange experiment. The promotion campaign allowed guests to pay any non negative amount of money for a stay in one of 36 hotels in Belgium and the Netherlands. The data allow us to distinguish between `regular guests', who booked prior to the announcement of the promotion campaign and guests who booked after the campaign was announced. During the promotion campaign we varied the posted price of a room that was communicated to the guests. Only the regular guests respond to the exogenous variation in the posted price and they pay substantially more on average. This different behavior cannot be explained by differences in satisfaction or observed compositional differences between both groups. We argue that the promotion campaign mainly attracted individuals who find it relatively unimportant to be viewed of as prosocial.

The literature has shown the power of social norms to promote residential energy conservation, particularly among high usage users. This study uses a natural field experiment with nearly 200,000 US households to explore whether a financial rewards program can complement such approaches. We observe strong impacts of financial rewards, particularly amongst low-usage and low-variance households, customers who typically are less responsive to normative messaging. Our data thus suggest important policy complementarities between behavioral and financial incentives: whereas non-pecuniary interventions disproportionally affect intense users, financial incentives are able to affect substantially low-user, "sticky households."

Previous studies of income distribution have found evidence indicating that incomes across U.S. regions have converged, supporting the prediction of the neoclassical growth model. A potential shortcoming in these studies is that only one measure of well-being is considered a measure of wealth linked to incomes or production. This paper examines whether income convergence was accompanied by air pollutant emission convergence. Results from unit root tests provide some evidence that indicators of environmental quality have converged across U.S. regions during the 1929-1994 period.

There is surprisingly little information about the delivery of health care in rural India, and about the relationship, if any, between health care and health status. Some, such as the Commission on Macroeconomics and Health of the World Health Organization (2001), have argued that better health care is the key to improving health as well as economic growth in poor countries, but there is little systematic evidence that gives us a sense of how easy it is to impact the quality of health care delivery in developing countries and through these improvements to impact the health of the population. This paper reports on a recent survey in a poor rural area of the state of Rajasthan in India intended to shed some light on this issue, where we use a set of interlocking surveys to collect data on health and economic status, as well as the public and private provision of health care.

An unsettling stylized fact is that decorated early childhood education programs improve cognitive skills in the short-term, but lose their efficacy after a few years. We implement a field experiment with two stages of randomization to explore the underpinnings of the fade-out effect. We first randomly assign preschool access to children, and then partner with the local school district to randomly assign the same children to classmates throughout elementary school. We find that the fade-out effect is critically linked to the share of classroom peers assigned to preschool access-with enough treated peers the classic fade-out effect is muted. Our results highlight a paradoxical insight: while the fade-out effect has been viewed as a devastating critique of early childhood programs, our results highlight that fade-out is a key rational for providing early education to all children. This is because human capital accumulation is inherently a social activity, leading early education programs to deliver their largest benefits at scale when everyone receives such programs.

Prior research finds that, conditional on an encounter, minority civilians are more likely to be punished by police than white civilians. An open question is whether the actual encounter is related to race. Using high-frequency location data of rideshare drivers operating on the Lyft platform in Florida, we estimate the effect of driver race on traffic stops and fines for speeding. Estimates obtained across traditional and machine learning approaches show that, relative to a white driver traveling the same speed, minorities are 24 to 33 percent more likely to be stopped for speeding and pay 23 to 34 percent more in fines. We find no evidence that these estimates can be explained by racial differences in accident and re-offense rates. Our study provides key insights into the total effect of civilian race on outcomes of interest and highlights the potential value of private sector data to help inform major social challenges.

Commitment devices for savings could benefit those with self-control as well as familial or spousal control issues. We find evidence to support both motivations. We examine the impact of a commitment savings product in the Philippines on household decision making power and self-perception of savings behavior, as well as actual savings. The product leads to more decision making power in the household for women, and likewise more purchases of female-oriented durable goods. We also find that the product leads women who appear time-inconsistent in a baseline survey to self-report being a disciplined saver in the follow-up survey. For impact on savings balances, we find that the 81% increase in savings after one year did not crowd out savings held outside of the participating bank, but that the longer-term impact over two and a half years on bank savings dissipated to only a 33% increase, which is no longer statistically significant. We discuss reasons why the effect dissipated and the implications for designing and implementing sustainable, equilibrium-shifting interventions.
