This paper investigates the role of dry promotions for community participation in eight Brazilian fishing villages. We randomly promoted some fishermen to assistants before the start of an environmental program, increasing their responsibilities but not providing any monetary compensation. Thereafter, we study whether they engage more in conservation behavior during this program. The data shows that promoted fishermen provide substantially more effort, which suggests that such promotions my be a cost-effective tool to stimulate cooperation and community participation.

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.

We conduct a natural field experiment with over 200 customers at a grocery store to investigate dynamic inconsistency and the demand for commitment in food choice. Subjects are invited to allocate and re-allocate food items received as part of a grocery delivery program. We observe substantial dynamic inconsistency, as well as a demand for commitment among a non-negligible number of subjects. Interestingly, individuals who demand commitment are more likely to be dynamically consistent in their prior behavior. This work provides direct evidence of dynamic inconsistency in consumption choices in the field and points towards potential extensions to models of temptation.

A large, but inconclusive, literature addresses how economic heterogeneity affects the use of local resources and local environmental quality. One line of thought, which derives from Nash equilibrium provision of public goods, suggests that in contexts in which individual actions degrade local environmental quality, wealthier people in a community will tend to do more to protect environmental quality. In this paper we report on experiments performed in rural Colombia that were designed to explore the role that economic inequality plays in the 'provision' of local environmental quality. Subjects were asked to decide how much time to devote to collecting firewood from a local forest, which degrades local water quality, and how much to unrelated pursuits. Economic heterogeneity was introduced by varying the private returns to these alternative pursuits. Consistent with the Nash equilibrium prediction, we found that the players with more valuable alternative options put less pressure on local water quality. However, the subjects with less valuable alternative options showed significantly more restraint relative to their pure Nash strategies. Furthermore, they were willing to bear significantly greater opportunity costs to move their groups to outcomes that yielded higher average payoffs and better water quality than the Nash equilibrium outcome.

We report results from a randomized evaluation comparing three school-based HIV/AIDS interventions in Kenya: 1) training teachers in the Kenyan Government's HIV/AIDS-education curriculum; 2) encouraging students to debate the role of condoms and to write essays on how to protect themselves against HIV/AIDS; and 3) reducing the cost of education. Our primary measure of the effectiveness of these interventions is teenage childbearing, which is associated with unprotected sex. We also collected measures of knowledge, attitudes, and behavior regarding HIV/AIDS. After two years, girls in schools where teachers had been trained were more likely to be married in the event of a pregnancy. The program had little other impact on students' knowledge, attitudes, and behavior, or on the incidence of teen childbearing. The condom debates and essays increased practical knowledge and self-reported use of condoms without increasing self-reported sexual activity. Reducing the cost of education by paying for school uniforms reduced dropout rates, teen marriage, and childbearing.

Whether lax environmental regulations are an important attraction for mobile capital remains one of the most controversial issues in the area of regulatory federalism. While the extant literature does a nice job of estimating the effects of environmental regulation on the spatial allocation of new plant births, one neglected area of research is the effect that environmental regulation has on plant relocation decisions. This paper uses an annual (1980-90) county level panel data set to examine the relationship between air quality regulatory stringency and the destination choice of relocating plants. We estimate empirical models using both parametric and semi-nonparametric specifications. Empirical results from both models suggest that air quality regulations alter significantly the destination choices of relocating plants.

Whether environmental regulations alter capital flows remains a hotly debated issue. This paper uses county-level data to examine the location decisions of domestic and foreign firms in a single empirical model and tests for asymmetries by firm origin in the degree to which capital flows are influenced by environmental standards. We find that while domestic firms are influenced by environmental regulations, foreign firms are not. Since the benefits of foreign investment are well-documented-foreign plants typically provide more jobs and increase local wages by more than domestic plants-this result suggests a double-dividend is available: foreign plants provide an economic stimulus and are not unduly influenced by environmental protections.

This study examines the effects of air quality regulation on economic activity. Anecdotal evidence and some recent empirical studies suggest that an inverse relationship exists between the stringency of environmental regulations and new plant formations. Using a unique county-level data set for New York State from 1980 to 1990, we revisit this conjecture using a seminonparametric method based on propensity score matching. Our empirical estimates suggest that pollution-intensive plants are responding to environmental regulations; more importantly, we find that traditional parametric methods used in previous studies may dramatically understate the impact of more stringent regulations.

Economic theory suggests that energy subsidies ca lead to excessive consumption and environmental degradation. However, the precise impact of energy subsidies is not well understood. We analyze a large energy subsidy: the California Alternate Rates for Energy (CARE). CARE provides a price reduction for low-income consumers of natural gas and electricity. Using a natural field experiment, we estimate the price elasticity of demand for natural gas to be about -0.35 for CARE customers. An economic model of this subsidy yields three results. First, the natural gas subsidy appears to reduce welfare. Second, the economic impact of various policies, such as cap-and-trade, depends on whether prices for various customers move closer to the marginal social cost. Third, benefits to CARE customers need to increase by 6% to offset the costs of the program.

The price elasticity of demand for credit has major implications for macroeconomics, finance, and development. We present estimates of this parameter derived from a randomized trial. The experiment was implemented by a consumer microfinance lender in South Africa and identifies demand curves that, while downward-sloping with respect to price, are flatter than recent estimates in both developing and developed countries throughout most of a wide price range. However, demand becomes highly price sensitive at higher-than-normal rates. We discuss several interpretations of this kink and present some related evidence. We also find that loan size is far more responsive to changes in loan maturity than to changes in interest rate. This pattern is more pronounced among lower income individuals, a comparative static that has been observed in the United States as well and is consistent with liquidity constraints that decrease with income.

Most charity organizations depend on contributions from the general public, but little research is conducted on donor preferences. Do donors have geographical, recipient, or thematic preferences? We designed a conjoint analysis experiment in which people rated development aid projects by donating money in dictator games. We find that our sample show strong age, gender, regional, and thematic preferences. Furthermore, we find significant differences between segments. The differences in donations are consistent with differences in donors' attitudes toward development aid and their beliefs about differences in poverty and vulnerability of the recipients. The method here used for development projects can easily be adapted to elicit preferences for other kinds of projects that rely on gifts from private donors.

We design experiments to jointly elicit risk and time preferences for the adult Danish population. The experimental procedures build on laboratory experiments that have been evaluated using traditional subject pools. The field experiments utilize field sampling designs that we developed, and procedures that were chosen to be relatively transparent in the field with non-standard subject pools. Our overall design was also intended to be a general template for such field experiments in other countries. We examine the characterization of risk over a wider domain for each subject than previous experiments, allowing more precise estimates of risk attitudes. We also examine individual discount rates over six time horizons, as the first stage in a panel experiment in which we revisit subjects to test consistency and stability of responses over time. Risk and time preferences are heterogeneous, varying by observable individual characteristics. On a methodological level, we implement a refinement of existing procedures which elicits much more precise estimates, and also mitigates framing effects.

Mixing across racial and ethnic lines could spur understanding or inflame tensions between groups. We find that white students at a large state university randomly assigned African American roommates in their first year were more likely to endorse affirmative action and view a diverse student body as essential for a high-quality education. They were also more likely to say they have more personal contact with, and interact more comfortably with, members of minority groups. Although sample sizes are too small to provide definitive evidence, these results suggest students become more empathetic with the social groups to which their roommates belong.

This paper reports a surprising finding from an experiment on giving to welfare recipients. The experiment tests how offers of money in n-donor dictator games are affected by 1) donors' humanitarian and egalitarian values and 2) direct information about the recipients' work-preferences. People who are self-reported humanitarians and egalitarians have giving that is highly elastic with respect to the apparent worthiness of the recipient. Among high scoring humanitarian-egalitarians, the median offer to a recipient who appeared industrious was $5.00, while the median offer to a recipient who appeared lazy was only $1.00. Among low scoring humanitarian-egalitarians, the median offer was $1.00 in both conditions. I refer to this combination of altruism and equity/reciprocity as empathic responsiveness. This finding can be rationalized by a model of inequity aversion.

Nonparametric estimators provide a flexible means of uncovering salient features of auction data. Although these estimators are popular in the literature, many key features necessary for proper implementation have yet to be uncovered. Here we provide several suggestions for nonparamteric estimation of first-price auction models. Specifically, we show how to impose monotonicity of the equilibrium bidding strategy; a key property of structural auction models not guaranteed in standard nonparametric estimation. We further develop methods for automatic bandwidth selection. Finally, we discuss how to impose monotonicity in auctions with differering number of bidders, reserve prices, and auction-specific characteristics. Finite sample performance is examined using simulated data as well as experimental auction data.

Winners of randomly assigned initial public offering (IPO) lottery shares are significantly more likely to hold these shares than lottery losers 1, 6, and even 24 months after the random allocation. This effect persists in samples of wealthy and highly active investors, suggesting along with additional evidence that this type of "endowment effect" is not solely driven by portfolio inertia or wealth effects. The effect decreases as experience in the IPO market increases, but persists even for the most experienced investors. These results suggest that agents' preferences and/or beliefs about an asset are not independent of ownership, providing field evidence derived from the behavior of 1.5 million Indian stock investors which is in line with the large laboratory literature documenting endowment effects. We evaluate the extent to which prominent models of endowment effects and/or investor behavior can explain our results. A combination of inattention and non-standard preferences (realization utility) or non-standard beliefs (salience based probability distortions) appears most consistent with our findings.

In the past several decades academics and policymakers have grappled with how to augment the traditional classroom approach to enhance critical thinking skill formation. In this not, I take a different approach. I begin by developing a Critical Thinking Hierarchy, where from the bottom of the hierarchy upwards two key skills evolve: developing/assimilating empirical evidence to update one's beliefs (connecting the dots with empiricism) and putting the puzzle pieces together with conceptual reasoning (connecting the dots with abstract thought). Skills lower down in the hierarchy must be achieved before individuals can gain skills higher up. A key aspect of the CT skill formation process revolves around student's maturation from "fast thinking" to "slow thinking". My overall approach is useful because it at once defines critical thinking, pinpoints where improvements must be made for development, and provides a classroom playbook to enhance critical thinking skill formation.
