Many argue that organizations of the disadvantaged create positive externalities, and in particular strengthen the position of these groups in society. A natural inference is that these organizations should be subsidized. We argue that the benefits of expanding the operations of these groups must be set against the potential costs of weakening the role of the disadvantaged in these organizations. A prospective, randomized evaluation of a development program targeted at strengthening rural women's groups in western Kenya suggests that the program did not improve group strength or functioning as measured by participation rates, assistance to members, and assistance to other community projects. The funding did, however, change the very characteristics of the groups that made them attractive to funders in the first place. Younger, more educated women and women employed in the formal sector joined the groups, and men and better-educated and wealthier women moved into key leadership positions.

This paper evaluates a program in Kenya that encourages the production of export oriented crops by providing smallholder farmers with credit linked to agricultural extension and marketing services. We use an experimental design in which farmer selfhelp groups are randomly assigned to either a control group, a group receiving all DrumNet services, or a group receiving all services except credit. Among the services offered by DrumNet, credit is the most important. Since the production of export crops requires a significant investment in capital and inputs, without credit farmers are less likely to plant the mentioned crops. Overall, the results show that DrumNet is an effective model for encouraging the production of export oriented crops.

In Israel, as in many other countries, a high school matriculation certificate is required by universities and some jobs. In spite of the certificate's value, Israeli society is marked by vast differences in matriculation rates by region and socioeconomic status. We attempted to increase the likelihood of matriculation among low-achieving students by offering substantial cash incentives in two demonstration programs. As a theoretical matter, cash incentives may be helpful if low-achieving students reduce investment in schooling because of high discount rates, part-time work, or face peer pressure not to study. A small pilot program selected individual students within schools for treatment, with treatment status determined by previous test scores and a partially randomized cutoff for low socioeconomic status. In a larger follow-up program, entire schools were randomly selected for treatment and the program operated with the cooperation of principals and teachers. The results suggest the Achievement Awards program that randomized treatment at the school level raised matriculation rates, while the student-based program did not.

People respond to those who ask. Within the charitable fundraising community, the power of the ask represents the backbone of most fundraising strategies. Despite this, the optimal design of communication strategies has received less formal attention. For their part, economists have recently explored how communication affects empathy, altruism, and giving rates to charities. Our study takes a step back from this literature to examine how suggestions-a direct ask for a certain amount of money-affect giving rates. We find that our suggestion amounts affect both the intensive and extensive margins: more people give and they tend to give the suggested amount. Resulting insights help us understand why people give, why messages work, and deepen practitioners' understanding of how to use messages to leverage more giving.

Using a natural field experiment with factory workers where we introduce a quantity-based performance-pay scheme in addition to their base salary, we quantify the impact of one-dimensional monetary incentives on both incentivized (quantity) and non-incentivized (quality) dimensions of output. While the management typically observes only quantity, we also observe quality by hiring quality-inspectors unbeknownst to the workers. While some workers receive a flat-rate base salary, others receive a piece-rate base salary. We find sharp evidence that workers under a flat-rate base salary trade off quality for quantity. Interestingly, this quantity-quality trade-off is statistically insignificant for workers under a piece-rate base salary. This variation in the treatment effect is consistent with a simple theoretical model that predicts that when agents are already incented at the margin, the quantity-quality trade-off resulting from additional incentives will be less prominent.

Default options have been shown to affect behavior in a variety of economic choice tasks, including health care and retirement savings. Less research has tested whether defaults affect behavior in the domain of energy efficiency. This study uses data from a randomized controlled experiment in which the default settings on office thermostats in an OECD office building were manipulated during the winter heating season, and chosen thermostat setting observed over a six week period. Using difference-in-differences, panel, and censored regression models (to control for maximum allowable thermostat settings), we find that small decreases in the default led to a greater reduction in chosen settings than large decreases. We also find that office occupants who are more apt to adjust their thermostats prior to the intervention were less susceptible to the default. We find no evidence that offices with multiple occupants displayed different patterns in thermostat choices than single-occupant offices. We conclude that this kind of intervention can increase building energy efficiency, and discuss broader policy implications of our findings.

Academic journal editors reject a significant portion of first submissions without sending them out for peer review. This decision, desk rejection, is made to reduce the workload on associate editors and referees, to give the submitting author a head start on revision or pursuit of an alternative venue, as well as to achieve quicker turnaround time for the journal. Desk rejection is a judgement based on the manuscript's perceived quality, impact and fit with the journal's scope. Could extraneous factors which are unrelated to the content of the manuscript, affect the editorial decision? This paper examines whether the sequential order in which manuscripts are submitted to a large academic journal affects the editorial decision. Becoming the first submission on the editor's list of manuscripts to review increases the probability of a desk rejection by up to 7% without any effect on the likelihood of a rejection after peer review.

We use field and natural experiments in online auctions to study the revenue effect of varying the level and disclosure of shipping charges. Our main findings are (1) disclosure affects revenues-for low shipping charges, a seller is better off disclosing; and (2) increasing shipping charges boosts revenues when these charges are hidden. These results are not explained by changes in the number of bidders.

In this paper, we propose a decision framework where people are individually asked to either actively consent or dissent to some pro-social behavior. We hypothesize that confronting individuals with the choice of engaging in a specific pro-social behavior contributes to the formation of issue-specific altruistic preferences while simultaneously involving a commitment. The hypothesis is tested in a large-scale field experiment on blood donation. We find that this "active-decision" intervention substantially increases the stated willingness to donate blood, as well as the actual donation behavior of people who have not fully formed preferences beforehand.

An extensive literature demonstrates the existence of framing effects in the laboratory and in questionnaire studies. This paper reports new evidence from a natural field experiment using a subject pool one might expect to be particularly resistant to such effects: experimental economists. We find that while the behaviour of junior experimental economists is affected by the description of the decision task they face, this is not the case for the more senior members of our subject pool.

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

We conducted two matching grant experiments with an international development charity. The primary experiment finds that a matching grant from the Bill and Melinda Gates Foundation raises more funds than a matching grant from an anonymous donor. The effect persists, and is strongest for donors who previously gave to other poverty-oriented charities. Combining these insights with survey results, we conclude that our matching gift primarily works through a quality signal mechanism. Overall, the results help to clarify why people give to charity, what models help to describe those motivations, and how practitioners can leverage economics to increase their fundraising potential.

Recent theoretical and empirical studies have explored the effect of group membership and identity on individual decision-making. This line of research highlights that economic models focusing on the individual as the sole entity in the decision-making environment potentially miss critical features. This study takes this literature in a new direction by overlaying a field experiment onto a setting where groups have arisen naturally. Our experimental laboratory is large open air markets, where we are able to examine the effects of group membership on seller's collusive behavior as measured by prices and surplus allocations. This permits us to explore strategic implications of group composition. Empirical results illustrate the importance of group composition on pricing decisions, and show that deviations from Nash equilibrium are crucially related to group membership.

In this paper we examine temporal properties of eleven natural resource real price series from 1870-1990 by employing a Lagrangian Multiplier unit root test that allows for two endogenously determined structural breaks with and without a quadratic trend. Contrary to previous research, we find evidence against the unit root hypothesis for all price series. Our findings support characterizing natural resource prices as stationary around deterministic trends with structural breaks. This result is important in both a positive and normative sense. For example, without an appropriate understanding of the dynamics of a time series, empirical verification of theories, forecasting, and proper inference are potentially fruitless. More generally, we show that both pre-testing for unit roots with breaks and allowing for breaks in the forecast model can improve forecast accuracy.

The literature has shown the power of social norms to promote residential energy conservation, particularly among high usage users. This study uses a natural field experiment with nearly 200,000 US households to explore whether a financial rewards program can complement such approaches. We observe strong impacts of financial rewards, particularly amongst low-usage and low-variance households, customers who typically are less responsive to normative messaging. Our data thus suggest important policy complementarities between behavioral and financial incentives: whereas non-pecuniary interventions disproportionally affect intense users, financial incentives are able to affect substantially low-user, "sticky households."

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.
