How to hire voluntary helpers? We shed new light on this question by reporting a field experiment in which we invited 2859 students to help at the 'ESA Europe 2012' conference. Invitation emails varied non-monetary and monetary incentives to convince subjects to offer help. Students could apply to help at the conference and, if so, also specify the working time they wanted to provide. Just asking subjects to volunteer or offering them a certificate turned out to be significantly more motivating than mentioning that the regular conference fee would be waived for helpers. By means of an online-survey experiment, we find that intrinsic motivation to help is likely to have been crowded out by mentioning the waived fee. Increasing monetary incentives by varying hourly wages of 1, 5, and 10 Euros shows positive effects on the number of applications and on the working time offered. However, when comparing these results with treatments without any monetary compensation, the number of applications could not be increased by offering money and may even be reduced.

We conducted an experiment with 30,000 users of a virtual nanotechnology facility, nanoHUB.org. We investigate the effect of virtual points and message framing on user participation in a survey. In one treatment, users receive points for completing the survey. In another treatment, users are exposed to a visual observation cue. We vary the social message, either emphasizing the private benefit to the user or the social benefit to the community of participation. Participation rates are increased through virtual points and for users receiving the private benefit messaging. The observation cue doesn't have an effect.

Given the importance of job placement for Ph.D.s, it is surprising that economists have not closely examined the factors that affect procuring job interviews for new Ph.D. economists.' In this study, I investigated those factors using a data set gathered at the 1997 American Economic Association (AEA) meetings in New Orleans. My purpose was to increase the information available to Ph.D. candidates who wish to maximize their postgraduation job prospects. In addition, this study may guide undergraduates and master's candidates who seek to pursue a Ph.D. in economics. The results of the findings, however, could benefit more than job seekers-they may provide academic departments and private industry with a comparative baseline for making decisions to interview job candidates. The job market for new Ph.D.s consists of two submarkets-academic and businesshndustry. The following are questions regarding job seekers in both submarkets. (1) Do employers in academia seek the same attributes as businesshndustry? (2) Is there discrimination in the interview decision? (3) Is an MBA important in the Ph.D. market? (4) How many more interviews are secured by candidates with a finished dissertation? (5) How important are teaching and research credentials? (6) Are graduates from top-ranked programs given special consideration in the job market? (7) Do personal letters of recommendation or calls from professors make a difference in the interview decision? (8) How influential are recommendation letters from prestigious economists? (9) What is the marginal effect of submitting another application? A simple theoretic construct provides a basis for understanding the two-step job-search process carried out by new Ph.D. economists.* In the first step, the job seeker decides whether to enter one or both submarkets and determines the optimal number of applications to submit. The second step reflects the actual decision process regarding acceptance or rejection of a job offer. Because a natural prerequisite to securing a job is an initial interview, my main focus in this study was to discover the optimal job search strategies for new Ph.D. economists by determining applicant characteristics that are conducive to obtaining interviews.

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.

The wealthiest 10% of donors now give 90% of charitable dollars in the U.S., but little is known about what motivates them. This study uses a natural field experiment, tracking over five thousand high capacity donors, to lend preliminary insights into the world of high capacity givers. On some dimensions, high capacity donors mirror modal donors: there is persistence in giving patterns, signals of program quality influence giving, and the price of giving is not unduly important. Unlike typical small donors, the givers in our data respond only on the intensive margin, and often with a longer time lag. Our study highlights the value to practitioners of partnering with academics, as our intervention has generated $30 million in incremental donations to the University.

An active area of research within economics concerns the underpinnings of why people give to charitable causes. This study takes a new approach to this question by exploring motivations for giving among children aged 3-5. Using data gathered from 122 children, our artefactual field experiment naturally permits us to disentangle pure altruism and warm glow motivators for giving. We find evidence for the existence of pure altruism but not warm glow. Our results suggest pure altruism is a fundamental component of our preferences, and highlight that warm glow preferences found amongst adults likely develop over time. One speculative hypothesis is that warm glow preferences are learned through socialization.

Measuring preferences via stated methods remains the only technique to obtain the total economic value of a non-marketed good or service. This study examines if alternative causes of an environmental problem affect individual statements of compensation demanded. Making use of a unique sample drawn from the Netherlands, we find that Hicksian equivalent surplus (ES) is not significantly affected by causes of environmental harm. While our finding that agents only care about outcomes, rather than causes, is consonant with standard applications of utility theory, it is at odds with some recent experimental findings measuring the effects of cause on Hicksian compensating surplus (CS).

We investigate the effect of different interactive technologies on the decision-making process in an information search laboratory experiment. In our experiment, the participant makes a selection from a list of differently-valued objects with multiple attributes. We compare presenting information in static form to two methods of interactive presentation. In the first, the participant can manually sort objects by attribute, a capability similar to that found in spreadsheet software. In the second, we present an interactive visual tool that (1) automatically sorts all objects by attribute and (2) uses visual cues for comparisons. Manual sorting capability does not cause an improvement in decisions in this context. On the other hand, the visual tool increases the value of the objects selected by the participant and decreases time spent deliberating. We also find that our interactive presentations affect the decision-making process of participants by changing the number of intermediate options considered. Our results highlight the importance of investigating the effect of technology on information search, and suggest that appropriate interactive visual displays may improve search in practice.

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.

A stylized fact is that agents respond more acutely to negative than positive stimuli. Such findings have generated insights on mechanism-design, have been featured prominently in policymaking, and more generally have led to discussions of whether preferences are defined over consumption levels or changes in consumption. This study reconsiders this stylized fact. In doing so, it provides insights into an important domain wherein positive stimuli induce a greater response than negative stimuli: a principal-agent game with reputational considerations and with the agent on the market's short end. This common setting represents an important feature of labor markets with involuntary unemployment.

We therefore agree with the sentiments of Bailey et al. (1) and Daly (2): Our study should not be viewed as the definitive study on this topic but as a proof of concept, which should propel researchers to exploit this unique sample to its fullest advantage. Further research using noncognitive measures, as well as alternative spatial measures would prove invaluable in addressing some of the shortcomings pointed out by Bailey et al. (1) and Daly (2). Moreover, such research would reveal the generality of our results and could focus activist efforts on traits that are most amenable to nurture. Also, if the measures are chosen to be more or less gender-dimorphic and more or less influenced by motivation, stereotype threat, and training, for example, this research, in addition to addressing some of the astute criticisms of Bailey et al. (1) and Daly (2), could also reveal mechanism, which would likewise be invaluable for focusing activists' efforts. We welcome collaboration with psychologists and anthropologists, such as the experts to whom this letter replies, to help us develop such measures of spatial and nonspatial cognitive abilities that are easy to explain and quick to implement, to take full advantage of this unique sample.

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 goal of this paper is to provide an investigation of several approaches to valuing ecosystem services and to contribute additional techniques which may be used in evaluating 'green' GDP accounts. Our estimates focus on the ecosystem as a productive economic input, not a stock which is depreciated or depleted over time; as such, it differs with other concepts more frequently employed in green GDP accounting. Most of our results are derived from the analytical fiction that a single owner of the biosphere establishes a market for all ecological resources. This monopolist then appropriates all rents from the human population. The maximum amount the monopolist charges is first assumed to be world gross product less the global human subsistence level. In addition, we examine the excess rents available in factor markets using the assumption of weak complementarity between factor inputs and ecosystem services. We also provide more conservative estimates of the value of ecosystem services by investigating the sustainable price the monopolist could charge the global population and by exploring the effects of compensating wage differentials and a non-monopolist owner of the ecosystem.

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 public goods problem (Hardin, 1968) either viewed as a problem of extraction or that of contribution has had a long history in the Social Sciences.Our experimental design uses a standard Voluntary Contributions Mechanism (VCM) game with a moderately large group of ten and face-to-face communication. The subjects, who are villagers in the Gori-Ganga Basin of the Central Himalayas, are not re-matched every period.Our results are somewhat different from laboratory experiments using a similar design such as Isaac and Walker (1988a, 1988b). A noteworthy general observation is that even with a relatively low Marginal Per Capita Return (MPCR = 0.2) and a large group we find a steady contribution rate around 55 percent, which diminishes slightly at the end of the session to around 45 percent. We also delve into the demographic characteristics of our subject pool and find that individual contribution to the common pool is determined by gender, age, caste, literacy and history of cooperation in the experiment. However, face-to-face communication is not seen to increase average individual contribution to the common pool.

Problems that arise in online markets due to asymmetric information are exacerbated by the fact that transactions in these markets are completely anonymous. The online auction mechanism provided by eBay is an example of such a market. To combat the anonymity problem, eBay allows sellers to become "ID Verified" by paying a small fee to have their identity confirmed by a credit information company. Doing so may reassure potential bidders that the seller is legitimate since their identity is known, and there is more assurance that the seller could be tracked down and punished should a problem arise. Identifying the effect of ID verification is difficult using naturally occurring data, however, because the service tends to be used only by sellers who have a well-established reputation. It is thus difficult to determine whether an improved outcome is due to the seller's reputation or due to ID verification. This study alleviates this concern by conducting a field experiment where items are sold with different IDs that have different characteristics, and finds little evidence that bidders place any value on ID verification.

We use a field experiment to investigate the effect of incentives on food purchase decisions at a grocery store. We recruit over 200 participants and track their purchases for a period of 6 months, permitting us a glimpse of more than 3,500 individual shopping trips. We randomize participants to one of several treatments, in which we incentivize fresh fruit and vegetable purchases, provide tips for fruit and vegetable preparation, or both. We report several key insights. First, our informational content treatment has little effect. Second, we find an important price effect: modest pecuniary incentives more than double the proportion of dollars spent on produce in the grocery store. Third, we find an interesting pattern of consumption after the experiment ends: even when incentives are removed, the treatment group has higher fruit and vegetable purchases compared to the control group. These long-term results are in stark contrast to either a standard price model or a behavioral model of 'crowd out.' Rather, our results are consonant with a habit formation model. This opens up the distinct possibility that short term incentives can be used as a key instrument to combat obesity.
