Advocates of teacher incentive programs argue that they can strengthen weak incentives, while opponents argue they lead to teaching to the test.' We find evidence that existing teacher incentives in Kenya are indeed weak, with teachers absent 20% of the time. We then report on a randomized evaluation of a program that provided primary school teachers in rural Kenya with incentives based on students' test scores. Students in program schools had higher test scores, significantly so on at least some exams, during the time the program was in place. An examination of the channels through which this effect took place, however, provides little evidence of more teacher effort aimed at increasing long-run learning. Teacher attendance did not improve, homework assignment did not increase, and pedagogy did not change. There is, however, evidence that teachers increased effort to raise short-run test scores by conducting more test preparation sessions. While students in treatment schools scored higher than their counterparts in comparison schools during the life of the program, they did not retain these gains after the end of the program, consistent with the hypothesis that teachers focused on manipulating short-run scores. In order to discourage dropouts, students who did not test were assigned low scores. Program schools had the same dropout rate as comparison schools, but a higher percentage of students in program schools took the test.

Many forest ecosystems provide multiple goods and services to both local users (e.g. firewood, water) and to other external beneficiaries (biodiversity conservation, carbon sequestration). This calls for alternative approaches in the governance of these local ecosystems. Even if local users solve the commons dilemma they face regarding the optimal provision of the direct benefit, there might still be a need for introducing mechanisms that also address the externality that involves those outside of the group. This paper addresses the analysis of different types of mechanisms, endogenously emerged from groups vs. externally imposed to them, when facing the typical tragedy of the commons. During 2000_2002 we conducted a series of economic experiments in several rural communities in Colombia. The sub-set reported here of 53 sessions with 265 actual users of local ecosystems, were focused specifically on the effect of external and self-governing rules for inducing cooperative behavior within groups. A group extraction or 'commons' game was used to explore how rules, formal and informal, emerge and how individual behavior responds to regulatory mechanisms aimed at solving the dilemma. Three treatments were compared to a baseline design: Two external regulations (high and low penalties, and only 20% of the players monitored), and a self-governed system where individuals were allowed to have in each round a few minutes of non-binding face-to-face communication. Surprisingly, both external regulations generated very similar results regardless of the level of the penalty, and they induced behaviors very similar to those achieved by the self-governed treatment. The experimental results suggest that individuals do not seem to follow entirely the conventional economic prediction of a minimizer of expected costs of regulations against the benefits from over extracting the resource, and that humans can develop norms based on non-enforceable rules of cooperation. Instead, other elements related to social norms and subjective valuation of the benefits and costs of the regulations might be in play.

Walrasian tatonnement has been a fundamental assumption in economics ever since Walrasian general equilibrium theory was introduced in 1874. Nearly a century after its introduction, Vernon Smith relaxed the Walrasian tatonnement assumption by showing that neoclassical competitive market theory explains the equilibrating forces in double-auction markets. I make a next step in this evolution by exploring the predictive power of neoclassical theory in decentralized naturally occurring markets. Using data gathered from two distinct markets--the sports card and collector pin markets--I find a tendency for exchange prices to approach the neoclassical competitive model prediction after a few market periods.

Pairs of carefully-matched, written applications were made to advertised job vacancies in England to test for sexual discrimination in hiring. Two standard resumes were constructed for each occupation to control for all relevant supply-side variables, such as qualifications, experience and age. Consequently any differential response recorded can be attributed to demand-side discrimination. Statistically significant discrimination against men was found in the `female occupation' - secretary, and against women in the `male occupation' - engineer. Statistically significant, and unprecedented, discrimination against men was found in two `mixed occupations' - trainee chartered accountant and computer analyst programmer.

Assumptions of individual rationality and preference stability provide the foundation for a convenient and tractable modeling approach. While both of these assumptions have come under scrutiny in distinct literatures, the two lines of research remain disjointed. This study begins by explicitly linking the two literatures while providing insights into perhaps the central issue facing behavioral economics today: to what extent does market experience mitigate various forms of individual irrationality? We find considerable evidence that the market is a catalyst for rationality. The study then focuses on aggregate market outcomes by examining empirically whether individual rationality is a prerequisite for market efficiency. Using field data gathered from more than 380 subjects of age 6-18 in multi-lateral bargaining markets at a shopping mall, we find that the market is a filter of irrationality--even when markets are populated solely by irrational buyers, aggregate market outcomes quickly converge to neoclassical predictions.

This paper estimates the risk preferences of cotton farmers in Southern Peru, using the results from a multiple-price-list lottery game. Assuming that preferences conform to two of the leading models of decision under risk--Expected Utility Theory (EUT) and Cumulative Prospect Theory (CPT)--we find strong evidence of moderate risk aversion. Once we include individual characteristics in the estimation of risk parameters, we observe that farmers use subjective nonlinear probability weighting, a behavior consistent with CPT. Interestingly, when we allow for preference heterogeneity via the estimation of mixture models--where the proportion of subjects who behave according to EUT or to CPT is endogenously determined--we find that the majority of farmers' choices are best explained by CPT. We further hypothesize that the multiple switching behavior observed in our sample can be explained by nonlinear probability weighting made in a context of large random calculation mistakes; the evidence found on this regard is mixed. Finally, we find that attaining higher education is the single most important individual characteristic correlated with risk preferences, a result that suggests a connection between cognitive abilities and behavior towards risk.

Play in the traditional trust experiment depends both on trust beliefs and on levels of risk aversion. We ran two experiments with a diverse set of subjects in fifteen villages of rural Paraguay, the traditional trust experiment and a new experiment measuring only risk aversion. We find that risk attitudes are highly predictive of play in the trust game. In addition, omitting risk aversion as a regressor in trust regressions signficiantly changes the coefficients of important explanatory variables such as gender and wealth. We also use data on income and bet choice to calculate players' coefficients of relative risk aversion.

Economic decisions depend on both actual outcomes as well as perceived intentions. In this paper, we examine whether and how the relative importance of outcomes or intentions for economic decisions develops with age. We report the results of ultimatum games with children, teens and university students. We find that children and teens react systematically to perceived intentions, like university students do. However, children and teens reject unequal offers much more often than university students, indicating that outcomes are relatively more important than intentions for younger subjects. Hence, the relative importance of intentions increases with age.

A field study of altruistic behaviour is presented using a modification of the dictator game in a large random sample survey in the Netherlands (n=1,964). In line with laboratory experiments, only 5.7% donated money. In line with other survey research on giving, generosity increased with age, education, income, trust, and prosocial value orientation.

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.

We experimentally investigate the impact of recognizing contributors on public good contributions. We vary recognizing all, highest or lowest contributors. Consistent with previous studies, recognizing all contributors significantly increases contributions relative to the baseline. Recognizing only the highest contributors does not increase contributions compared to not recognizing contributors, while recognizing only the lowest contributors is as effective as recognizing all contributors. These findings support our conjecture that aversion from shame is a more powerful motivator for giving than anticipation of prestige.

Do men and women have different social preferences? Previous findings are contradictory. We provide a potential explanation using evidence from a field experiment. In a door-to-door solicitation, men and women are equally generous, but women become less generous when it becomes easy to avoid the solicitor. Our structural estimates of the social preference parameters suggest an explanation: women are more likely to be on the margin of giving, partly because of a less dispersed distribution of altruism. We find similar results for the willingness to complete an unpaid survey: women are more likely to be on the margin of participation.

In a laboratory one-shot public good game, Fischbacher, Gachter and Fehr (2001) classify 50 percent of the subjects as conditional cooperators. Outside the lab, using a student sample, Frey and Meier (2005) find that people behave pro-socially, conditional on others' behavior. This paper tests for conditional cooperation and social comparisons in a natural field experiment, using decisions from a sample of cross-country skiers in Sweden on the issue of voluntary cash contributions to the preparation of ski tracks. Two test procedures are used. First, testing for correlation between beliefs about the contribution of others and own behavior and second, experimentally varying the beliefs about others' behavior. Using the latter approach, I find the share of subjects giving a contribution to be significantly greater in the group receiving information about others' behavior than in the group that does not. Regression analysis cannot reject that subjects are affected by social comparisons and express a behavior classified as conditional cooperation.

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.

Standard applications of utility theory assume that utility depends solely on outcomes and not on causes. This study uses a field experiment conducted in the Netherlands to determine if alternative causes of an environmental problem affect willingness to pay to ameliorate it. We find evidence supporting the hypothesis that people are willing to pay significantly more to correct problems caused by humans than by nature (the "outrage effect"), but find no support for the hypothesis that "moral responsibility" matters. We also find support for the hypothesis that stated willingness to pay values obtained via "cheap talk" and "consequential" treatments are lower than without inclusion of these protocols.

Stricter environmental regulations are often opposed on the grounds that they will alter equilibrium capital flows. Empirical evidence in this area remains largely unresolved, mainly due to the quite disparate results found in the literature. This paper takes a positive look at the relationship between new manufacturing plant location decisions and environmental regulations by examining data from 11 studies that provide more than 365 observations. One major result from our meta-analysis is that methodological considerations play a critical role in shaping the body of received estimates. Our empirical estimates also lend insights into future research that is necessary before any robust conclusions can be made regarding the effects of environmental regulations on capital flows.

This paper calibrates real and hypothetical willingness-to-accept estimates elicited for consumer goods in a multi-unit, random nth-price auction. Using a within-subject experimental design, we find that people understated their real willingness to accept in the hypothetical regimes, framed both as demand and non-demand revealing. After controlling for personspecific effects, however, hypothetical and real statements are equivalent on the margin.

This paper uses a randomized field experiment to examine several approaches to reducing corruption. I measure missing expenditures in over 600 village road projects in Indonesia by having engineers independently estimate the prices and quantities of all inputs used in each road, and then comparing these estimates to villages' official expenditure reports. I find that announcing an increased probability of a government audit, from a baseline of 4 percent to 100 percent, reduced missing expenditures by about 8 percentage points, more than enough to make these audits cost-effective. By contrast, I find that increasing grass-roots participation in the monitoring process only reduced missing wages, with no effect on missing materials expenditures. Since materials account for three-quarters of total expenditures, increasing grass-roots participation had little impact overall. The findings suggest that grass-roots monitoring may be subject to free-rider problems. Overall, the results suggest that traditional top-down monitoring can play an important role in reducing corruption, even in a highly corrupt environment.

We employ a two-step modified count data model to determine the county-level attributes that are conducive to attracting new foreign plants. Our estimation results indicate that previous counts of foreign direct investment, market size and accessibility, and land area are positively related to Foreign Direct Investment (FDI) occurrences; while higher input costs deter new foreign firm entry. Contrary to anecdotal evidence, our results suggest that stringent environmental regulations do not have a negative impact on FDI inflows. These findings have significant implications for policymakers, as flows of FDI are expected to increase dramatically given the economic integration of our global economy.
