Models of job tournaments and competitive workplaces more generally predict that while individual effort may increase as competition intensifies between workers, the incentive for workers to cooperate with each other diminishes. We report on a field experiment conducted with workers from a fishing community in Toyama Bay, Japan. Our participants are employed in three different aspects of fishing. The first group are fishermen, the second group are fish wholesalers (or traders), and the third group are staff at the local fishing coop. Although our participants have much in common (e.g., their common relationship to the local fishery and the fact that they all live in the same community), we argue that they are exposed to different amounts of competition on-the-job and that these differences explain differences in cooperation in our experiment. Specifically, fishermen and traders, who interact in more competitive environments are significantly less cooperative than the coop staff who face little competition on the job. Further, after accounting for the possibility of personality-based selection, perceptions of competition faced on-the-job and the treatment effect of job incentives explain these differences in cooperation to a large extent.

We report results from two surveys of representative samples of Americans with private health insurance. The first examines how well Americans understand, and believe they understand, traditional health insurance coverage. The second examines whether those insured under a simplified all-copay insurance plan will be more likely to engage in cost-reducing behaviors relative to those insured under a traditional plan with deductibles and coinsurance, and measures consumer preferences between the two plans. The surveys provide strong evidence that consumers do not understand traditional plans and would better understand a simplified plan, but weaker evidence that a simplified plan would have strong appeal to consumers or change their healthcare choices.

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.

The in-group-out-group bias is among the most widely documented and analyzed phenomenon in the social sciences. We conduct field experiments to test whether the bias extends to the cooperative behavior of one of the most successful modern collectives, the Israeli kibbutz. Despite their promise as universal cooperators, kibbutz members are more cooperative toward anonymous kibbutz members than they are toward anonymous city residents. In fact, when paired with city residents, kibbutz members' observed levels of cooperation are identical to those of city residents. Moreover, self-selection rather than kibbutz socialization largely accounts for the extent to which kibbutz members are cooperative.

We conduct experiments in urban slums to measure trust and cooperation and to see how behavior varies with demographic factors and associational measures of social capital. Overall, we find high contribution rates among Thai and Vietnamese participants in a voluntary contribution game, and we see that many participants are willing to signal their disapproval of free riding despite it being costly to do so. At the individual level, we find that behavior varies with many demographic factors and with many associational factors. However, these correlations often differ significantly between our two locations, indicating the role of culture, defined broadly.

Economists have paid increasing attention to the role of cultural diversity in explaining the variability of economic outcomes across societies. We develop an experimental framework that complements existing research in this area. We implement the framework with two cultures that coexist in an industrialized society: the Hispanic and Navajo cultures in the southwestern United States. We vary the ethnic mix of our experimental sessions in order to infer the effect of intercultural interactions on economic behavior and outcomes. We control for demographic differences in our subject pools and elicit beliefs directly in order to differentiate between statistical discrimination and preference-based discrimination. We present clear evidence that Hispanic and Navajo subjects behave differently and that their behavior is affected by the ethnic composition of the experimental session. Our experimental framework has the potential to shed much needed light on economic behavior and outcomes in societies of mixed ethnicity, race and religion.

We use field experiments with nearly 900 children to investigate how skills developed at ages 3-5 drive later-life outcomes. We find that skills map onto three distinct factors - cognitive skills, executive functions, and economic preferences. Returning to the children up to 7 years later, we find that executive functions, but not cognitive skills, predict the likelihood of receiving disciplinary referrals. Economic preferences have an independent effect: children who displayed impatience at ages 3-5 were more likely to receive disciplinary referrals. Random assignment to a parenting program reduced disciplinary referrals. This effect was not mediated by skills or preferences.

Social scientists for years have documented the pervasiveness of discrimination in product and labor markets. While the literature has recently attempted to measure the nature of such discrimination, much less work has been done exploring the origins of discrimination. We make a modest step in this direction by reporting data from a field experiment attempting to measure discrimination amongst 3-5 years olds. Using a design that isolated discriminatory behaviors in economic games, we find that both White and Hispanic children send more resources to Black children than White children, whereas black children send equal amounts. This provides a first glimpse that suggests preferences amongst the young do not show similar patterns as preferences of adults.

Although social capital has been considered of the utmost importance for development it remains a complex and elusive concept. Different dimensions of social capital form part of the puzzle: cooperation is an individual other-regarding preference; social norms stem from beliefs about others' behavior; and the formation of such beliefs is mediated by attributes of the social network. To disentangle social capital we conduct an artefactual field experiment with 714 households at the inset of a Conditional Cash Transfer program in an urban context. To our knowledge this is the first paper that disentangles cooperation from coordination by conducting a minimum effort coordination game with Pareto ranked equilibria. Willingness to cooperate is teased out using a public goods game. By controlling for the density of network information we capture the role of connections, which is the third element of the mixture. We also look at the relation between our experimental data and traditional survey measures of social capital. Our identification strategy allows us to assess whether exposure to the program could be helping individuals overcome strategic uncertainty and select the most efficient equilibrium in the coordination game. The regressions suggest that the program helps overcome the coordination failure through different channels. In particular, the evidence suggests there is a spillover effect of the monetary incentive as it facilitates a social norm, which itself allows individuals to overcome the coordination failure. We rule out confounding factors such as individual socio-economic characteristics, social capital accumulation, willingness to cooperate and connectivity.

Acts of dishonesty permeate life. Understanding their origins, and what mechanisms help to attenuate such acts is an underexplored area of research. This study takes an economics approach to explore the propensity of individuals to act dishonestly across different contexts. We conduct an experiment that includes both parents and their young children as subjects, exploring the roles of moral cost and scrutiny on dishonest behavior. We find that the highest level of dishonesty occurs in settings where the parent acts alone and the dishonest act benefits the child. In this spirit, there is also an interesting, quite different, effect of children on parents' behavior: parents act more honestly under the scrutiny of daughters than under the scrutiny of sons. This finding sheds new light on the origins of the widely documented gender differences in cheating behavior observed among adults, where a typical result is that females are more honest than males.

The current social dilemma literature lacks theoretical consensus regarding how individuals behave when facing multiple simultaneous social dilemmas. The divided-loyalty hypothesis, from organizational theory, predicts that cooperation will decline as individuals experience multiple social dilemmas with different compared to the same group members. The conditional-cooperation hypothesis, from behavioral economics, predicts that cooperation will increase as individuals experience multiple social dilemmas with different compared to the same group members. We employ a laboratory experiment to create consensus between these literatures and find support for the conditional-cooperation hypothesis. The positive effect of interacting with different group members comes from participants having an opportunity to shift their cooperative behavior from the less cooperative to the more cooperative group.

It is common in organizational life to be simultaneously involved in multiple collective actions. These collective actions may be modeled using public good dilemmas. The developing social dilemma literature has two perspectives - the "divided loyalties" and "conditional cooperation" perspectives - that give opposite predictions about how individuals will behave when they simultaneously play two identical public good games. The current paper creates consensus between these social dilemma perspectives by examining cooperative behavior of participants interacting in two public good games with either different or the same group members. In each round, individuals have a common budget constraint across the two games. In support of the conditional cooperator's perspective of social dilemmas, we find that playing two games with different, rather than same, group members increases overall contributions. Over the course of the experiment, participants playing two games with different group members shift their contributions significantly more often toward more cooperative public good games than participants playing with the same group members.

Time-consuming and costly religious rituals pose a puzzle for economists committed to rational choice theories of human behavior. We propose that either through selection or a causal relationship, the performance of religious rituals is associated with higher levels of cooperation. To test this hypothesis we design field experiments to measure the in-group cooperative behavior of members of religious and secular Israeli kibbutzim, communal societies for which mutual cooperation is a matter of survival. Our results show that religious males (the primary practitioners of collective religious ritual in Orthodox Judaism) are more cooperative than religious females, secular males and secular females. Moreover, the frequency with which religious males engage in collective religious rituals predicts well their degree of cooperative behavior.

I examine treatment effect heterogeneity within an experiment to inform external validity. The local average treatment effect (LATE) gives an average treatment effect for compliers. I bound and estimate average treatment effects for always takers and never takers by extending marginal treatment effect methods. I use these methods to separate selection from treatment effect heterogeneity, generalizing the comparison of OLS to LATE. Applying these methods to the Oregon Health Insurance Experiment, I find that the treatment effect of insurance on emergency room utilization decreases from always takers to compliers to never takers. Previous utilization explains a large share of the treatment effect heterogeneity. Extrapolations show that other expansions could increase or decrease utilization.

This paper discusses voluntary contributions to health education in a shanty town in Peru, using a new experimental setup to identify voluntary contributions to local public goods. The experiment enables individuals to contribute to a health education meeting facilitated by an NGO, which they know will only be organised if the cumulative investment level exceeds a certain threshold value. In contrast to expectations of aid distributors, individuals contributed a substantial amount of money, despite the long-term nature of the health benefits from health education. High discount rates only seem to have had a detrimental effect on investment in a poorer subsample. Results from a complementary experiment, which identifies donations to a nutrition program, suggest that positive beliefs about short-term benefits from health education in the form of learning effects have played an important role in the investment decision. The results indicate that channelling decision-making power about public good provision to beneficiaries not necessarily implies a crowding out of investment in local public goods with long-term benefits. Hence, particular attention is given to the potential role of cash transfers in the financing of local public goods.

Two behavioral concepts, loss aversion and mental accounting, have recently been combined to provide a theoretical explanation of the equity premium puzzle. Recent experimental evidence suggests that undergraduate students' behavior is consistent with this "myopic loss aversion" conjecture. Our suspicion is that, much like certain anomalies in the realm of riskless decisions, these behavioral tendencies will be severely attenuated when real market players are put to the task. Making use of a unique subject pool-professional futures and options pit traders recruited from the Chicago Board of Trade-we do find behavioral differences between professionals and students. Yet, rather than discovering that the anomaly disappears, the data suggest that professional traders exhibit myopic loss aversion to a greater extent than undergraduate students.

Evidence that individuals have dynamically consistent preferences is usually generated by studying the discount rates of the individual over different horizons, but where those rates are elicited at a single point in time. If these elicited discount rates vary by horizon, the individual is typically claimed to have preferences that imply a dynamic inconsistency, although this inference requires additional assumptions such as intertemporal separability. However, what one really wants to know is if the same subject has the same discount rate function when that individual is asked at a later point in time. Such panel tests then require that one allow for possible changes in the states of nature that the subject faces, since they may confound any in-sample comparisons of discount rate functions at different points in time. We report the results of a large-scale panel experiment undertaken in the field that allows us to examine this issue. In June 2003, we elicited subjective discount rates from 253 subjects, representative of the adult Danish population. Between September 2003 and November 2004, we re-visited 97 of these subjects and repeated these tasks. In each visit, we also elicited information on their individual characteristics, as well as their expectations about the state of their own economic situation and macroeconomic variables. We find evidence in favor of dynamic consistency.
