Empirical evidence suggesting that a considerable amount of horizontal strategic interaction exists amongst governments is important in light of recent devolutionary trends of many important public programs. The empirical approach in these studies typically relies on estimating reaction functions in a uni-dimensional policy framework, where a nonzero slope estimate is interpreted as evidence in support of strategic interactions. While this framework is a useful representation within certain contexts, it is potentially too restrictive; for example, in models of resource competition, localities may use multiple instruments in their recruiting pursuits, leading to potential strategic interactions across policy instruments. In this study, we first develop a simple theoretic construct that includes resource competition in a world of three-dimensional policy choice. The model suggests that while a zero-sloped reaction function may exist for any particular policy, this does not necessarily imply the absence of strategic interactions. We examine the implications of the model empirically using US state-level panel data over the period 1977-1994. The results suggest that important cross-policy strategic interactions exist, lending support in favor of the multi-dimensional framework, and indicate that uni-dimensional frameworks may present lower bound estimates of the degree of strategic interaction.

Across domains, people struggle to follow through on their commitments. This can happen for many reasons, including dishonesty, forgetfulness, or insufficient intrinsic motivation. Social scientists have explored the reasons for persistent failures to follow through. suggesting that eliciting explicit promises can be an effective way to motivate action. This paper presents a field experiment that tests the effect of explicit promises, in the form of "honor pledges", on loan repayment rates. The experiment was conducted with LendUp, an online lender, and targeted 4,883 first time-borrowers with the firm. Individuals were randomized into four groups, with the following experimental treatments: (1) having no honor pledge to complete (control); (2) signing a given honor pledge; (3) re-typing the same honor pledge as in (2) before signing; and (4) coming up with a personal honor pledge to type and sign. I also randomized whether or not borrowers were reminded of the honor pledge they signed prior to repayment deadline. The results suggest that the honor pledge treatments had minimal impacts on repayment, and that reminders of the pledges were similarly ineffective. This suggests that borrowers who fail to repay loans do so not because of dishonesty or behavioral biases, but because they suffer from true financial hardship and are simply unable to repay.

We use a field experiment in Sierra Leone to examine how the identity of the manager influences rent seeking and performance in participatory development projects. Specifically, we vary the composition of a committee responsible for implementing a development project-local elites or randomly selected villagers. The design is unique in that it permits us to explore the effectiveness of two alternative local governance modalities and the extent of elite capture in community projects. We find little evidence that local elites capture project resources. We do observe they are better managers of development projects. Improved performance covaries with a proxy for power of the local chief.

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.

Auditing is a technique used to test for discrimination. The concept is straightforward: Two individuals are matched on all relevant characteristics except the one presumed to lead to discrimination. Each person then applies for the same job, housing, mortgage loan, or credit card. The differential treatment they receive provides a measure of discrimination. The authors argue that the value of auditing has grown in the current legal and political environment because it can detect subtle forms of discrimination.

I conducted a field experiment in Benin to investigate the impact of clientelism on voting behavior. In collaboration with four political parties involved in the 2001 presidential elections, clientelist and broad public policy platforms were designed and run in twenty randomly selected villages of an average of 756 registered voters. Even after controlling for ethnic affiliation, I find that clientelist platforms have significant effects on voting behavior. The effect was strongest for incumbent and for "local" candidates. The evidence indicates that female voters tend to prefer "national" candidates, especially when they run on public policy platforms. In contrast, male voters tend to prefer "local" candidates especially when they run on clientelist platforms.

Procrastination, an issue linked to poor performance and decreased well-being, is a pervasive problem in education. This paper examines the role of commitment and motivation by evaluating a program called CollegeBetter.com which acts as a commitment device and monetary incentive to help college students battle problems of present bias. The zero-sum mechanism is based off a parimutuel betting market, where students join a pool by placing a monetary wager on themselves to achieve the pool's "commitment challenge." Students who successfully commit to the challenge 1) recover their wagers and 2) split losing wagers proportionally. Through a series of lab and field experiments, I find that students interested in the mechanism were low-achieving, overconfident, self-identified procrastinators, while traditional measures of time-preferences were weak predictors of selection. Across all pools, students randomly selected to participate were more likely to achieve the commitment challenge than students who applied for a spot but were randomly excluded. Consistent with loss aversion, having the student risk their own money is a principal contributor to the effectiveness of the mechanism.

Behavioral economics and field experiments within the social sciences have advanced well beyond academic curiosum. Governments around the globe as well as the most powerful firms in modern economies employ staffs of behavioralists and experimentalists to advance and test best practices. In this study, we combine behavioral economics with field experiments to reimagine a new model of early childhood education. Our approach has three distinct features. First, by focusing public policy dollars on prevention rather than remediation, we call for much earlier educational programs than currently conceived. Second, our approach has parents at the center of the education production function rather than at its periphery. Third, we advocate attacking the macro education problem using a public health methodology, rather than focusing on piecemeal advances.

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.

Researchers, using contingent valuation (CV) to value changes in nonmarket goods, typically believe respondents always answer questions truthfully or they answer truthfully only when it is in their interest to do so. The second position, while consistent with economic theory, implies that interpreting survey responses depends critically on the incentive structure provided. We derive simple tests capable of distinguishing the two views. Our theoretical model for examining the incentive structure of a single binary choice relaxes the usual expected utility assumption. We test our theory using a field experiment involving voting to provide a public good. Experimental results are consistent theoretical predictions and cast doubt on the relevance of a large experimental literature using inconsequential questions and non-incentive-compatible mechanisms to make inferences about CV. The framework put forth should help in understanding the role played by theoretical conditions for preference elicitation and lend insight into the hypothetical bias literature.

We explore collusion by using the tools of experimental economics in a naturally occurring marketplace. We report that competitive price theory adequately organizes data in multilateral decentralized bargaining markets without conspiratorial opportunities. When conspiratorial opportunities are allowed and contract prices are perfectly observed, prices (quantities) are considerably above (below) competitive levels. When sellers receive imperfect price signals, outcomes are intermediate to those of competitive markets and collusive markets with full information. Finally, experienced buyers serve as a catalyst to thwart attempts by sellers to engage in anticompetitive pricing: in periods where experienced agents transact in the market, average transaction prices are below those realized in periods where only inexperienced agents execute trades.

Economists accept consumer frauds as an equilibrium outcome of information costs. This paper empirically investigates what information is costly, what contribute to the information costs, and what institutions are more effective in reducing the information costs. We focus on one of the most complained about markets - Internet auctions. In a field experiment, we obtain actual baseball cards from both online and retail markets whose quality are then professionally graded and compared to the prices paid by online buyers for goods with similar claims. The experiment allows us to obtain a key variable - true quality - on top of price and seller ratings used in the existing literature. Our findings indicate that some naive buyers in the online ungraded market are misled by non-credible claims of quality. They pay higher prices but do not receive better quality and in fact are defrauded more often. In comparison, claim-driven frauds do not exist in retail or graded markets where buyers can observe card quality either through careful quality examination before purchase or a third-party grading service. Online seller reputation is found to be effective for identifying good-faith sellers. But conditional on completed auctions, reputable sellers do not provide better quality. More disturbingly, the price increase from making non-credible claims more than compensates for the lower likelihood of sale for sellers with low reputations. We attribute the naivete to misleading signals in the online ungraded market and two loopholes in the eBay rating system, namely universal rating and costless switching of anonymous identities. These loopholes reduce the precision and accessibility of seller information, and therefore add difficulties for naive buyers to become sophisticated. We also point out that naive buyers could impose several negative externalities on the other good-faith players in the market.

Results in behavioral economics suggest that material incentives can crowd out effort, if agents are mission-oriented rather than self-interested. We test this prediction on a sample of nonprofit organizations in Sweden. Swedish nonprofit organizations receive tax funds annually to promote global development issues through information campaigns. Traditionally, the contract with the main principal (the Swedish foreign aid agency) has been based on trust and self-regulation. We designed an experimental policy intervention, effectively replacing the trust-based contract with an increased level of monitoring from the principal, along with a threat to cut future funds if irregularities were detected. Our findings are inconsistent with (strong) motivational crowd-out. Overall, using both self-reported and observed measures of outreach, we find that the intervention improved efficiency. Graphical analysis shows that non-monitored organizations exhibit a distinct tendency to maximize expenditure; in contrast, organizations in the treatment group are more likely to return unused grants to Sida. Additionally, we find no crowding out of private contributions and no evidence of a "discouraged NGO"-syndrome.

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 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.

This paper examines the accuracy of beliefs about corruption, using data from Indonesian villages. Specifically, I compare villagers' stated beliefs about the likelihood of corruption in a road-building project in their village with a more objective measure of 'missing expenditures' in the project, which I construct by comparing the project's official expenditure reports with an independent estimate of the prices and quantities of inputs used in construction. I find that villagers' beliefs do contain information about corruption in the road project, and that villagers are sophisticated enough to distinguish between corruption in the road project and other types of corruption in the village. The magnitude of their information, however, is small, in part because officials hide corruption where it is hardest for villagers to detect. This may limit the effectiveness of grass-roots monitoring of local officials. I also find evidence of systematic biases in corruption beliefs, particularly when examining the relationship between corruption and variables correlated with trust. For example, ethnically heterogeneous villages have higher perceived corruption levels but lower actual levels of missing expenditures. The findings illustrate the limitations of relying solely on corruption perceptions, whether in designing anti-corruption policies or in conducting empirical research on corruption.

We examined the effect of an image of a pair of eyes on contributions to an honesty box used to collect money for drinks in a university coffee room. People paid nearly three times as much for their drinks when eyes were displayed rather than a control image. This finding provides the first evidence from a naturalistic setting of the importance of cues of being watched, and hence reputational concerns, on human cooperative behaviour.

The 1987 academic market was strong, whereas the 1997 market was weak. A multimarket theory of optimal search suggests that job seekers will respond to a weakening market by changing their search strategies at the extensive margin (which markets to enter) and the intensive margin (how many applications to submit per market). Employers respond to the weakening market by raising their hiring standards. High-quality applicants will obtain an increased share of academic interviews in weak markets while applicants from weaker schools will increasingly secure interviews outside of the academic market. Empirical results show that in the bust market, graduates of elite schools shifted their search strategies to include weaker academic institutions, while graduates of lower-ranked schools shifted their applications away from academia and toward the business sector. In bust conditions, academic institutions increasingly concentrate their interviews on elite school graduates, women, and U.S. residents

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.
