The economics literature suggests that enhanced social connection can increase trust amongst agents, which can ultimately lead to more efficient economic outcomes, including increased provision of public goods. This study provides a test of whether social connectedness (proxied via agent similarities in race and gender) influences giving to a charitable fundraiser. Using data gathered from more than 2000 households approached in an actual door-to-door fundraising drive, we find limited evidence of the importance of such social connections. A robust result in the data, however, is that our minority solicitors, whether approaching a majority or minority household, are considerably less likely to obtain a contribution, and conditional on securing a contribution, gift size is lower than their majority counterparts receive.

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.

The economic costs of environmental regulations have been widely debated since the U.S. began to restrict pollution emissions more than four decades ago. Using detailed production data from nearly 1.2 million plant observations drawn from the 1972-1993 Annual Survey of Manufactures, we estimate the effects of air quality regulations on manufacturing plants' total factor productivity (TFP) levels. We find that among surviving polluting plants, stricter air quality regulations are associated with a roughly 2.6 percent decline in TFP. The regulations governing ozone have particularly large negative effects on productivity, though effects are also evident among particulates and sulfur dioxide emitters. Carbon monoxide regulations, on the other hand, appear to increase measured TFP, especially among refineries. The application of corrections for the confounding of price increases and output declines and sample selection on survival produce a 4.8 percent estimated decline in TFP for polluting plants in regulated areas. This corresponds to an annual economic cost from the regulation of manufacturing plants of roughly $21 billion, about 8.8 percent of manufacturing sector profits in this period.

While confounding factors typically jeopardize the possibility to use observational data to measure peer effects, field experiments offer the possibility to obtain clean evidence. In this paper we measure the output of four randomly selected groups of individuals who were asked to fill letters in envelopes, with a remuneration completely independent of output. For two of these groups the output of peers was exogenously manipulated (low or high) by making individuals aware of the number of letters previously produced by artificial colleagues. In the third group individuals were set up to work one in front of the other, while the fourth group gave the baseline output for independent not manipulated work. Our first finding is that effort of the less productive workers reacts in a sizeable and statistically significant way to peer pressure. Second, there is strong evidence of peer effects when individuals work in pairs. Third, these peer effects work in the direction of making the least productive individuals work harder, thereby increasing overall productivity.

This paper explores the origins of the strikingly high price premia paid for new food products in lab valuation exercises. Our experimental design distinguishes between two explanations of this phenomenon: novelty of the experimental experience versus the novelty of the good, i.e., preference learning-bids reflect a person's desire to learn how an unfamiliar good fits into their preference set. Subjects bid in four consecutive experimental auctions for three goods that vary in familiarity, candy bars, mangos, and irradiated meat. Our results suggest that preference learning is the main source of the high premia, and that novelty of the experimental experience does not in itself artificially inflate valuations.

Kenya's education system blends substantial centralization with elements of local control and school choice. This paper argues that the system creates incentives for local communities to build too many small schools; to spend too much on teachers relative to non-teacher inputs; and to set school fees that exceed those preferred by the median voter and prevent many children from attending school. Moreover, the system renders the incentive effects of school choice counterproductive by undermining the tendency for pupils to switch into the schools with the best headmasters. A randomized evaluation of a program operated by a non-profit organization suggests that budget-neutral reductions in the cost of attending school and increases in non-teacher inputs, financed by increases in class size, would greatly reduce dropout rates without reducing test scores. Moreover, evidence based on transfers into and out of program schools suggests that the population would prefer such a reallocation of expenditures.

We design a model-based field experiment to estimate the nature and magnitude of workers' social preferences towards their employers. We hire 446 workers for a one-time task. Within worker, we vary (i) piece rates; (ii) whether the work has payoffs only for the worker, or also for the employer; and (iii) the return to the employer. We then introduce a surprise increase or decrease in pay ('gifts') from the employer. We find that workers have substantial baseline social preferences towards their employers, even in the absence of repeated-game incentives. Consistent with models of warm glow or social norms, but not of pure altruism, workers exert substantially more effort when their work is consequential to their employer, but are insensitive to the precise return to the employer. Turning to reciprocity, we find little evidence of a response to unexpected positive (or negative) gifts from the employer. Our structural estimates of the social preferences suggest that, if anything, positive reciprocity in response to monetary 'gifts' may be larger than negative reciprocity. We revisit the results of previous field experiments on gift exchange using our model and derive a one-parameter expression for the implied reciprocity in these experiments.

This review steps back from the burgeoning economics literature on measuring social preferences and considers more carefully the empirical evidence from the lab and the field. I place the claims from the ardent supporters of the literature into three bins: one for claims that are supported by the data upon closer scrutiny, one for claims that are not supported by the data upon closer scrutiny, and one for claims that may or may not be true. The third set of claims highlights important theoretical and empirical investigations that need to be done to further our understanding of the nature and import of social preferences.

We implemented the first web-based online field experiments of fund-raising. We embedded our experiment in the Internet Public Library to test four mechanisms: Voluntary Contribution (VCM), Premium, Seed Money and Matching. Although the gift size is not significantly different across mechanisms, the Seed and Matching mechanisms each generate significantly higher user click-through response rate than the Premium mechanism. Because this is one of the earliest embedded, web-based field experiments, we report our methodology findings in some detail. Cookies work better as participant assignment techniques than pop-up windows and elicitation of geographic information. Participant clickstream data that nominally demonstrate a desire to donate is a poor predictor of actual giving.

Using the data from sealed offer laboratory markets, we compare the price and quality choices of student subjects with those of businessmen subjects. The businessmen subjects were public accounting firm partners and corporate financial officers. This is of interest since the financial officer-auditor relationship is one particular application of the elementary principal-agent model which the laboratory environment was designed to test. Using several different performance measures we are unable to reject the null hypothesis that the average performance of the two subject pools were the same. However, the market using businessmen subjects generally exhibited greater variance than the market using students.

Economic research examining how educational intervention programs affect primary and secondary schooling focuses largely on test scores although the interventions can affect many other outcomes. This paper examines how an educational intervention, a voucher program, affected students' altruism. The voucher program used a lottery to allocate scholarships among low-income applicant families with children in K-8th grade. By exploiting the lottery to identify the voucher effects, and using experimental economic methods, we measure the effects of the intervention on childrens altruism. We also measure the voucher programs effects on parents' altruism and several academic outcomes including test scores. We find that the educational intervention positively affects students' altruism towards charitable organizations but not towards their peers. We fail to find statistically significant effects of the vouchers on parents' altruism or test scores.

The minimax argument represents game theory in its most elegant form: simple but with stark predictions. Although some of these predictions have been met with reasonable success in the field, experimental data have generally not provided results close to the theoretical predictions. In a striking study, Palacios-Huerta and Volij (2007) present evidence that potentially resolves this puzzle: both amateur and professional soccer players play nearly exact minimax strategies in laboratory experiments. In this paper, we establish important bounds on these results by examining the behavior of four distinct subject pools: college students, bridge professionals, world-class poker players, who have vast experience with high-stakes randomization in card games, and American professional soccer players. In contrast to Palacios-Huerta and Volij's results, we find little evidence that real-world experience transfers to the lab in these games--indeed, similar to previous experimental results, all four subject pools provide choices that are generally not close to minimax predictions. We use two additional pieces of evidence to explore why professionals do not perform well in the lab: (1) complementary experimental treatments that pit professionals against preprogrammed computers, and (2) post-experiment questionnaires. The most likely explanation is that these professionals are unable to transfer their skills at randomization from the familiar context of the field to the unfamiliar context of the lab.

Recently an important line of research using laboratory experiments has provided a new potential reason for why we observe gender imbalances in labor markets: men are more competitively inclined than women. Whether, and to what extent, such preferences yield differences in naturally-occurring labor market outcomes remains an open issue. We address this question by exploring job-entry decisions in a natural field experiment where we randomized nearly 7,000 interested job-seekers into different compensation regimes. By varying the role that individual competition plays in setting the wage, we are able to explore whether competition, by itself, can cause differential job entry. The data highlight the power of the compensation regime in that women disproportionately shy away from competitive work settings. Yet, there are important factors that attenuate the gender differences, including whether the job is performed in teams, whether the job task is female-oriented, and the local labor market.

In their landmark study of a field experiment, Gerber and Green (2000) found that get-out-the-vote calls reduce turnout by five percentage points. In this article, I introduce statistical methods that can uncover discrepancies between experimental design and actual implementation. The application of this methodology shows that Gerber and Green's negative finding is caused by inadvertent deviations from their stated experimental protocol. The initial discovery led to revisions of the original data by the authors and retraction of the numerical results in their article. Analysis of their revised data, however, reveals new systematic patterns of implementation errors. Indeed, treatment assignments of the revised data appear to be even less randomized than before their corrections. To adjust for these problems, I employ a more appropriate statistical method and demonstrate that telephone canvassing increases turnout by five percentage points. This article demonstrates how statistical methods can find and correct complications of field experiments.

Social scientists have presented evidence that suggests discrimination is ubiquitous: women, nonwhites, and the elderly have been found to be the target of discriminatory behavior across several labor and product markets. Scholars have been less successful at pinpointing the underlying motives for such discriminatory patterns. We employ a series of field experiments across several market and agent types to examine the nature and extent of discrimination. Our exploration includes examining discrimination based on gender, age, sexual orientation, race, and disability. Using data from more than 3000 individual transactions, we find evidence of discrimination in each market. Interestingly, we find that when the discriminator believes the object of discrimination is controllable, any observed discrimination is motivated by animus. When the object of discrimination is not due to choice, the evidence suggests that statistical discrimination is the underlying reason for the disparate behavior.

Political stock markets have a long history in the United States. Organized prediction markets for Presidential elections have operated on Wall Street (1880-1944), the Iowa Electronic Market (1988-present), and TradeSports (2001-present). Proponents claim such markets efficiently aggregate information and provide forecasts superior to polls. An important counterclaim is that such markets may be subject to manipulation by interested parties. We analyze this argument by studying alleged and actual speculative attacks- large trades, uninformed by fundamentals, intended to change prices- in these three markets. We first examine the historical Wall Street markets where political operatives from the contending parties actively and openly bet on city, state and national races; the record is rife with accusations that parties tried to boost their candidates through investments and wash bets. Next we report the results of a field experiment involving a series of planned, random investments-- accounting for two percent of total market volume-- in the Iowa Electronic Market in 2000. Finally, we investigate the speculative attacks on TradeSports market in 2004 when a single trader made a series of large investments in an apparent attempt to make one candidate appear stronger. In the cases studied here, the speculative attack initially moved prices, but these changes were quickly undone and prices returned close to their previous levels. We find little evidence that political stock markets can be systematically manipulated beyond short time periods.

Whether rationality of economic behavior increases with expected payoffs and decreases with the cognitive cost it takes to formulate an optimal strategy remains an open question. We explore these issues with field data, using individual bids from sealed-bid auctions in which we sold nearly $10,000 worth of sportscards. Our results indicate that stakes do indeed matter, as high-priced ($70) cards produced more of the theoretically predicted strategic behavior than did lower-priced ($3) cards. We find additional evidence consistent with the importance of cognitive costs, as subjects more experienced with sportscard auctions exhibited a greater tendency to behave strategically than did less experienced bidders.

Recent research has posited that, in advanced economies, there is a positive correlation between income inequality and development. Using a new unbalanced panel dataset for 71 countries from 1961 to 1992, we present evidence that supports this conjecture. Although many factors may be contributing to this renewed positive relationship between growth and inequality, one plausible explanation rests on the shift away from a manufacturing base towards a service base in most advanced economies.
