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.

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 article analyzes the validity and reliability of using the results of behavioral experiments in stimulating businessmen in real life situation. 301 samples of various fields namely business and non-business managers, students and military personnels were taken for the experiment. The businesss situation taken was that a manager had abruptly discharged his subordinate on the context of performance. The subjects were required to make a letter of advocacy and also were asked to write their opinion on the firing done by the manager. The letter of advocacy was the subject's effort, in writing, to support the point of view assigned to him. One point of view had the subject approving the manager's method of firing the subordinate and the other point of view had him disapproving. If change in opinion for both groups of advocates had occurred toward one point of view and not toward the other, then the change could have been reasonably attributed to bias in the topic. Military personnel showed the least significant opinion changes in advocating either of the two points of view. On the other extreme, business managers showed rather highly significant changes irrespective of point of view advocated.

In this paper, we distinguish between horizontal and vertical trust. We investigate how these measures of trust, as well as measures of trustworthiness and risk aversion are related to the probability of rural farmers of having had a loan from a bank. Using experimental and survey data from 191 farmers of the Amazon region of Ecuador, we find that: (1) controlling for risk aversion, women do not trust differently than men in each trust game, however, women compared to men do trust outside professionals more than community members, and (2) isolated rural farmers with stronger preferences for trusting outside professionals experience higher levels of bank loan uptake.

We build on previous work in the charitable giving literature by examining not only how much subjects give to charity, but also which charities subjects prefer. We operationalize this choice in an artefactual field experiment with a representative sample of respondents. We then use these data to structurally model motives for giving. The novelty of this design allows us to ask several interesting questions regarding the choices one undertakes when deciding both whether and how much to give to charity. Further, we ask these questions in the context of a standard utility framework. Given the unique set up of this experiment, we also explore how these distributional preference parameters differ by charity choice and from what we have observed in the past. We find that there is more variation within demographics and charity types than across distributions.

En esta ponencia queremos explorar, a partir de nuestros resultados de investigacion, posibles puentes de complementariedad y sinergia entre la economia experimental y los m_todos participativos de investigacion, para poder estudiar problemas rurales, en particular aquellos asociados al uso de recursos naturales por parte de las comunidades. Desde el 1er semestre del 2001 hasta la fecha hemos realizado una serie de talleres y experimentos economicos en varias comunidades del pas. En esta ponencia vamos a hacer referencia a los tres estudios de caso que se realizaron en el proyecto "Regulacion de Recursos Comunitarios: Ejercicios economicos en el campo" que se llevaron a cabo en el Neusa y la Vega en Cundinamarca, y el Parque Sanquianga en Nario. El proposito de estos estudios de caso era estudiar los problemas del uso comunitario de recursos como la pesca, la piangua y o el agua en una microcuenca. En cada comunidad se realizaron 26 sesiones de experimentos economicos con participacion de 130 campesinos en cada comunidad; igualmente se llevaron a cabo talleres y ejercicios desde el Diagnostico Rural Participativo (DRP) para discutir con los mismos participantes tanto los resultados de los experimentos como la problem_tica asociada al uso de estos recursos naturales. Dicha informacion fue sistematizada con el fin de contrastar los tres casos, y las posibles consistencias entre dos aproximaciones (economia experimental y herramientas participativas) que hasta el momento no han sido utilizadas de manera conjunta ni para las mismas situaciones. Como se presentar_, la economia experimental ofrece potencialidades interesantes para estudiar la validez de los modelos economicos de comportamiento de las personas frente a, por ejemplo, los dilemas del uso de recursos colectivos; igualmente puede ofrecer informacion muy detallada y verificable acerca de las decisiones micro de las personas; por su parte las metodolog?as participativas permiten explicar procesos y situaciones que un agente externo dif?cilmente puede comprender acerca de las causalidades e interacciones de factores que afectan la problem_tica de una comunidad. A traves de estos instrumentos podemos mostrar como estas dos metodologias pueden de una manera eficaz responder a preguntas centrales acerca del uso comunitario de recursos.

Psychological insights have made inroads within most major areas of study in economics. One area where less advance has been made is environmental and resource economics. In this study, we examine the implications of preference reversals over evaluation modes, in which stated economic values critically depend on whether the good is valued jointly with others or in isolation. The question arises because two commonly used methods for eliciting stated preferences differ in that one presents objects together and another presents objects to be evaluated in isolation. Beyond showing an example of the import of behavioral economics, our empirical evidence sheds new light on the factors associated with insensitivity of valuations to the scope of the good

Auction theory represents one of the richest areas of research in economics over the past three decades. Yet, whether, and to what extent, the introduction of secondary resale markets influences bidding behavior in sealed bid first-price auctions remains under researched. This study begins by examining field data from a unique data set that includes nearly 3,000 auctions (over 10,000 individual bids) for cutting rights of standing timber in British Columbia from 1996-2000. In comparing bidding patterns across agents who are likely to have resale opportunities with those who likely do not, we find evidence that is consistent with theory. Critical evaluation of the reduced-form bidding model, however, reveals that sharp tests of the theoretical predictions are not possible because several other differences may exist across these bidder types. We therefore use a laboratory experiment to examine if the resale opportunity by itself can have the predicted theoretical effect. We find that while it does have the predicted effect, a theoretical model based on risk-averse bidders explains the overall data patterns more accurately than a model based on risk-neutral bidders. Beyond testing theory, the paper highlights the inferential power of combining naturally occurring data with laboratory data.

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.

This study examines strategic mortgage default on a neurological level. Specifically, we test two mainstream behavioral finance/economic theories: sunk cost fallacy and cognitive dissonance. Using fMRI technology, we identify a number of substrates within the brain that provide a neurobiological explanation for why some homeowners exercise their mortgage put option while others do not. We find that borrowers rationally do not suffer from the sunk cost fallacy as it relates to strategic default in that stye significantly prioritize their negative equity position over the amount of their initial down payment. We do, however, find neurological support that cognitive dissonance is relevant in homeowners' thought processes as they toil with the hesitancy brought on by the belief that strategic default is immortal against strong financial incentive to walk away from a substantially underwater mortgage.

Time preferences have been correlated with a range of life outcomes, yet little is known about their early development. We conduct a field experiment to elicit time preferences of nearly 1,000 children ages 3-12, who make several inter temporal decisions. To shed light on how such primitives form, we explore various channels that might affect time preferences, from background characteristics to the causal impact of an early schooling program that we developed and operated. Our results suggest that time preferences evolve substantially during this period with younger children displaying more impatience than older children. We also find a strong association with race: black children, relative to white or Hispanic children, are more impatient. Interestingly, parents of black children are also much more impatient than parents of white and Hispanic children. Finally, assignment to different schooling opportunities is not significantly associated with child time preferences.

In this study, we use functional magnetic resonance imaging (fMRI) to understand how homeowners process non-financial information when considering strategic mortgage default. We find that borrowers initially attempt to inhibit their knee-jerk reaction to retaliate against a lender who has engaged in egregious lending practices when compared to a financially conservative lender. Moreover, when defaults are rare, borrowers are less likely to default because violating the social norm results in feelings of disgust. Finally, when a lender refuses a loan modification, the borrower is found to seek retribution. Interestingly, granting even a modest loan modification removes the desire of homeowners to seek retribution towards their lender no matter what their impression of the lender may be. The results carry a number of policy implications.

Great debate is being waged between whether strategic mortgage defaulters follow a herd for social reasons or mimic others' behavior for informational gain. Using functional magnetic resonance imaging (fMRI), the latest neurological technology allowing for observation of brain activity during strategic mortgage default decision-making, we find that when defaulters learn of peer default behavior, they acknowledge the social component of the decision, but feel freer to make their own decisions. Alternatively, when observing the behavior of a maven (real estate expert), borrowers still consider the social aspect of the decision (although to a lesser extent), but ultimately follow the maven who presumably possesses a greater information set. Alarmingly, borrowers only significantly follow the herd when mavens advocate strategic default, not when they recommend against it.

We show that a number of "non cognitive" skills and preferences, including patience and identity, are malleable in adults, and that investments in them reduce crime and violence. We recruited criminally-engaged men and randomized half to eight weeks of cognitive behavioral therapy designed to foster self-regulation, patience, and a noncriminal identity and lifestyle. We also randomized $200 grants. Cash alone and therapy alone initially reduced crime and violence, but effects dissipated over time. When cash followed therapy, crime and violence decreased dramatically for at least a year. We hypothesize that cash reinforced therapy's impacts by prolonging learning-by-doing, lifestyle changes, and self-investment.

Research on competitiveness at the individual level has emphasized sex as a physiological determinant, focusing on the gap in preference for competitive environments between young men and women. This study presents evidence that women's preferences over competition change with age such that the gender gap, while large for young adults, disappears in older populations due to the fact that older women are much more competitive. Our finding that tastes for competition appear just as strong among older women as they are among men suggests a simple gender-based view of competitiveness is misleading; age seems just as important as sex. These findings are consistent with one of the most commonly cited views on the deeper origins of gender differences: that they stem at least in part from human evolution.
