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.

The ability to cooperate in collective action problems --such as those relating to the use of common property resources or the provision of local public goods --is a key determinant of economic performance. In this paper we discuss two aspects of collective action problems in developing countries. First, which institutions discourage opportunistic behavior and promote cooperation? Second, what are the characteristics of the individuals involved that determine the degree to which they cooperate? We first review the evidence from field studies, laboratory experiments, and cross community studies. We then present new results from an individual level panel data set of rural workers.

The wealthiest 10% of donors now give 90% of charitable dollars in the U.S., but little is known about what motivates them. This study uses a natural field experiment, tracking over five thousand high capacity donors, to lend preliminary insights into the world of high capacity givers. On some dimensions, high capacity donors mirror modal donors: there is persistence in giving patterns, signals of program quality influence giving, and the price of giving is not unduly important. Unlike typical small donors, the givers in our data respond only on the intensive margin, and often with a longer time lag. Our study highlights the value to practitioners of partnering with academics, as our intervention has generated $30 million in incremental donations to the University.

Controlled experiments, using matched pairs of bogus transactors, to test for discrimination in the marketplace have been conducted for over 30 years, and have extended across 10 countries. Significant, persistent and pervasive levels of discrimination have been found against non-whites and women in labour, housing and product markets. Rates of employment discrimination against non-whites, in excess of 25% have been measured in Australia, Europe and North America. A small number of experiments have also investigated employment discrimination against the disabled in Britain and the Netherlands, and against older applicants in the United States.

We study the effect of social information on the voluntary provision of public goods. Competing theories predict that others[1] contributions might be either substitutes or complements to one's own. We demonstrate a positive social information effect on individual contributions, supporting theories of complementarities. We find the most influential level of social information is drawn from the 90th to 95th percentile of previous contributions. We furthermore find the effect to be significant for new members but not for renewing members. In the most effective condition, social information increases contributions by 12% ($13). These increased contributions do not crowd out future contributions.

Exploiting findings that losses loom larger than gains, studies have shown that framing manipulations can increase productivity of workers. Using a natural field experiment that exogenously manipulates wage bonuses within contests in a Chinese high-tech manufacturing facility, we show that how loss aversion affects worker behavior critically depends on the incentive scheme as well as the framing manipulation. Four sets of two identical teams competed against each other to win a bonus given to the team, within a set, with the higher average hourly productivity over the week. In each set, the bonus was framed as a reward or gain for one team and as a punishment or loss for the other. Average weekly productivity was slightly higher under the loss treatment, but this increase was statistically insignificant. However, the team under the loss treatment was at least 35% more likely to win the contest. As teams' payoffs are based on relative productivity under a contest, framing effect is much stronger in terms of relative productivity. Finally, workers seemingly responded to the bonus by increasing the quality of production as well as quantity-defect rate fell as productivity increased.

In this paper we study the effect of downward social information in contribution decisions to fund public goods. We describe the results of a field experiment run in conjunction with the fundraising campaigns of a public radio station. Renewing members are presented with social information (information about another donor's contribution) which is either above or below their previous (last year's) contribution. We find that respondents change their contribution in the direction of the social information; increasing their contribution when the social information is above their previous contribution, and decreasing their contribution when the social information is below. We hypothesize about the psychological motivations that may cause the results and test these hypotheses by comparing the relative size of the upward and downward shifts. These results improve our understanding of cooperation in public good provision and suggest differential costs and benefits to fundraisers in providing social information.

This study explores the linkages between trade policy, corruption, and environmental policy. We begin by presenting a theoretical model that produces several testable predictions, including: (i) the effect of trade liberalization on the stringency of environmental policy depends on the level of corruption; and (ii) corruption reduces environmental policy stringency. Using panel data from a mix of developed and developing countries from 1982 to 1992, we find evidence that supports these conjectures. We view these results as representing an attempt at understanding the myriad of complex relationships that exist in an open economy.

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.

This paper examines the extent to which a noncompliant debtor can be induced to pay back the debt by sending a randomly assigned message via mobile phone and e-mail, ranging from a simple reminder to personalized messages and a social norm. In cooperation with a debt-collector enterprise in Latvia, the field experiment was carried out on 24,781 unique cases of consumer debts with unpaid liabilities, ranging from one to 40,060.26 euros. Overall, sending a message to a debtor increases compliance in comparison of not sending a message at all. However, messages, which include debtor's name, agent's name or social norm, do not increase compliance in comparison to a simple reminder message. I also looked at the interaction effect between the content of the message and the debt amount, which has been hardly examined in previous experiments on compliance. Messages with a debtor's name significantly increase compliance in comparison to a simple reminder among the debts smaller than 170 euros. However, such a message is counter-effective for debts larger than 1,340 euros, the same trend is true for a message with the social norm. Hence, a different policy needs to be applied to the debtors who are extensively overindebted in comparison to those with comparatively small debt amounts.

In this paper, we propose a decision framework where people are individually asked to either actively consent or dissent to some pro-social behavior. We hypothesize that confronting individuals with the choice of engaging in a specific pro-social behavior contributes to the formation of issue-specific altruistic preferences while simultaneously involving a commitment. The hypothesis is tested in a large-scale field experiment on blood donation. We find that this "active-decision" intervention substantially increases the stated willingness to donate blood, as well as the actual donation behavior of people who have not fully formed preferences beforehand.

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.

A vibrant literature has emerged that explores the economic implications of the sex ratio (the ratio of men to women in the population), including changes in fertility rates, educational outcomes, labor supply, and household purchases. Previous empirical efforts, however, have paid less attention to the underlying channel via which changes in the sex ratio affect economic decisions. This study combines evidence from a field experiment and a survey to document that the sex ratio importantly influences female bargaining power: as the sex ratio increases, female bargaining power increases.

We show that fixed costs of adjustment as opposed to low returns likely explain why better quality care practices diffuse slowly in the medical industry. Using a randomized field experiment conducted in Argentina, we find that temporary financial incentives paid to health clinics for the early initiation of prenatal care 'nudged' providers to test and develop new data driven strategies to locate and encourage likely pregnant women to seek care in the first trimester of pregnancy. These innovations raised the rate of early initiation of prenatal care by 34% while the incentives were being paid in the treatment period. We follow health clinics over time and find that this increase persisted for at least 24 months after the incentives ended. In the absence of incentives, even though it is in the clinics' interest to stimulate early initiation of care, the presence of hard to change habits and cost of experimentation made it too expensive to develop and implement new methods to increase early initiation of care. Despite the large increases in early initiation of prenatal care, we find no effects on health outcomes.

Recent discoveries in behavioral economics have led scholars to question the underpinnings of neoclassical economics. We use insights gained from one of the most influential lines of behavioral research -- gift exchange -- in an attempt to maximize worker effort in two quite distinct tasks: data entry for a university library and door-to-door fundraising for a research center. In support of the received literature, our field evidence suggests that worker effort in the first few hours on the job is considerably higher in the "gift" treatment than in the "non-gift treatment." After the initial few hours, however, no difference in outcomes is observed, and overall the gift treatment yielded inferior aggregate outcomes for the employer: with the same budget we would have logged more data for our library and raised more money for our research center by using the market-clearing wage rather than by trying to induce greater effort with a gift of higher wages.

This paper shows that accounting for variation in mistakes can be crucial for welfare analysis. Focusing on consumer underreaction to not-fully-salient sales taxes, we show theoretically that the efficiency costs of taxation are amplified by 1) individual differences in under reaction and 2) the degree to which attention is increasing with the size of the tax rate. To empirically assess the importance of these issues, we implement an online shopping experiment in which 2,998 consumers-matching the U.S. adult population on key demographics-purchase common household products, facing tax rates that vary in size and salience. We find that: 1) there are significant individual differences in underreaction to taxes. Accounting for this heterogeneity increases the efficiency cost of taxation estimates by at least 200%, as compared to estimates generated from a representative agent model. 2) Tripling existing sales tax rates roughly doubles consumers' attention to taxes. Our results provide new insights into the mechanisms and determinants of boundedly rational processing of not-fully-salient incentives, and our general approach provides a framework for robust behavioral welfare analysis.

We perform a field experiment to measure racial discrimination in the labor market. We respond with fictitious resumes to help-wanted ads in Boston and Chicago newspapers. To manipulate perception of race, each resume is assigned either a very African American sounding name or a very White sounding name. The results show significant discrimination against African-American names: White names receive 50 percent more callbacks for interviews. We also find that race affects the benefits of a better resume. For White names, a higher quality resume elicits 30 percent more callbacks whereas for African Americans, it elicits a far smaller increase. Applicants living in better neighborhoods receive more callbacks but, interestingly, this effect does not differ by race. The amount of discrimination is uniform across occupations and industries. Federal contractors and employers who list Equal Opportunity Employer' in their ad discriminate as much as other employers. We find little evidence that our results are driven by employers inferring something other than race, such as social class, from the names. These results suggest that racial discrimination is still a prominent feature of the labor market.
