Evidence suggests the calibration of hypothetical and actual behavior is good-specific. We examine whether clustering commodities into mutual categories can reduce the burden. While we reject a common calibration across sets of commodities, a sport-specific calibration function cannot be rejected.

Incomplete contracts are the rule rather than the exception, and any incentive scheme faces the risk of improving performance on incented aspects of a task at the detriment of performance on non-incented aspects. Recent research documents the effect of loss-framed versus gain-framed incentives on incentivized behavior, but how do such incentives affect overall performance? We explore potential trade-offs by conducting field experiments in an artificial "workplace". We explore two types of incentive spillovers: those contemporaneous to the incented task and those subsequent to the incented task. We report three main results. First, consonant with the extant literature, a loss aversion incentive induces greater effort on the incented task. Second, offsetting this productivity gain, we find that the quality of work decreases if quality is not specified in the incentive contract. Third, we find no evidence of harmful spillover effects to subsequent tasks; if anything, the loss aversion incentive induces more effort in subsequent tasks. Taken together, our results highlight that measuring and accounting for incentive spillovers are important when considering their overall impact.

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.

Previous empirical studies of information cascades use either naturally occurring data or laboratory experiments with student subjects. We combine attractive elements from each of these lines of research by observing market professionals from the Chicago Board of Trade (CBOT) in a controlled environment. As a baseline, we compare their behavior to student choices in similar treatments. We further examine whether, and to what extent, cascade formation is influenced by both private signal strength and the quality of previous public signals, as well as decision heuristics that differ from Bayesian rationality. Analysis of over 1,500 individual decisions suggests that CBOT professionals are better able to discern the quality of public signals than their student counterparts. This leads to much different cascade formation. Further, while the behavior of students is consistent with the notion that losses loom larger than gains, market professionals are unaffected by the domain of earnings. These results are important in both a positive and normative sense.

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.

We present the results of a novel early childhood intervention in which disadvantaged 3-4-year-old children were randomized to receive a new preschool and parents education program focused on cognitive and non-cognitive skills (CogX) or to a control group that did not receive preschool education. In addition to a typical academic year (9 month) program, we also evaluated a shortened summer version of the program (2 months) in which children were treated immediately prior to the start of Kindergarten. Both programs, including the shortened version, significantly improved cognitive test scores by about one quarter of a standard deviation relative to the control group at the end of the year. The shortened version of the program was equally as effective as the academic-year program because most of the gains in the academic-year program occurred within the first few months.

This special issue highlights an empirical approach that has increasingly grown in prominence in the last decade--field experiments. While field experiments can be used quite generally in economics to test theories' predictions, to measure key parameters, and to provide insights into the generalizability of empirical results, this special issue focuses on using field experiments to explore questions within the economics of charity. The issue contains six distinct field experimental studies that investigate various aspects associated with the economics of charitable giving. The issue also includes a fitting tribute to one of the earliest experimenters to depart from traditional lab methods, Peter Bohm, who curiously has not received deep credit or broad acclaim. Hopefully this issue will begin to rectify this oversight.

An important class of investment decisions is characterized by unrecoverable sunk costs, resolution of uncertainty through time, and the ability to invest in the future as an alternative to investing today. The options model provides guidance in such settings, including an investment decision rule called the "bad news principle": the downside investment state influences the investment decision whereas the upside investment state is ignored. This study takes a new approach to examining predictions of the options model by using the tools of experimental economics. Our evidence, which is drawn from student and professional trader subject pools, is broadly consonant with the options model.

This study develops theory and conducts an experiment to provide an understanding of why people initially give to charities, why they remain committed to the cause, and what factors attenuate these influences. Using an experimental design that links donations across distinct treatments separated in time, we present several insights. For example, we find that previous donors are more likely to give, and contribute more, than donors asked to contribute for the first time. Yet, how these previous donors were acquired is critical: agents who are initially attracted by signals of charitable quality transmitted via an economic mechanism are much more likely to continue giving than agents who were initially attracted by non-mechanism factors.

A concern with the contingent valuation method (CVM) is the finding that hypothetical and real statements of value often differ. We test whether hypothetical bias, broadly defined, is independent of location by comparing real and hypothetical votes on a dichotomous choice referendum in China, France, Indiana, Kansas, and Niger. We find significant differences in hypothetical bias across locations and reject the hypothesis that hypothetical bias is independent of location. As opposed to the typical finding reported in the literature, subjects in Niger significantly understated their willingness-to-pay in the hypothetical referendum.

A hallmark result within behavioral economics is that individuals' choices are affected by current endowments. A recent theory due to Koszegi and Rabin (2006) explains such endowment effect with a model of expectations-based reference-dependent preferences. Departing from past work, we conduct complementary experiments to disentangle expectations - verified probabilistic beliefs held by subjects - from other features of endowment - such as "assignment" to a good - hence allowing us to compare the effect of expectations with that of other variations. While mere assignment can affect choices, we do not find a large role in the effect for Koszegi-Rabin expectations.

Several recent laboratory experiments have shown that the use of explicit incentives--such as conditional rewards and punishment--entail considerable "hidden" costs. The costs are hidden in the sense that they escape our attention if our reasoning is based on the assumption that people are exclusively self-interested. This study represents a first attempt to explore whether, and to what extent, such considerations affect equilibrium outcomes in the field. Using data gathered from nearly 3000 households, we find little support for the negative consequences of control in naturally-occurring labor markets. In fact, even though we find evidence that workers are reciprocal, we find that worker effort is maximized when we use conditional--not unconditional--rewards to incent workers.

Socioeconomic inequalities in child development crystallize at early stages, with associated disparities in parental investment in children. A key to understanding the data patterns is to document the sources underlying the observed inequalities. We first show that there are dramatic differences in parental beliefs across socioeconomic backgrounds (SES), with parents of higher SES being more likely to believe that parental investments impact child development. We then use two field experiments targeted to low-SES families to explore the mutability of such beliefs and their link to parental investments. In both cases, we find that parental beliefs about child development are malleable. The less intensive version of the program based on educational videos changes parental beliefs, but fails to lastingly increase parental investments and child outcomes. By contrast, in the more intensive version of our program combining home visits and feedback, the augmented beliefs are associated with enriched parent-child interactions and improved vocabulary, math, and social-emotional skills for the children. Together, these results suggest that changing parental beliefs can be an important pathway to raising parental investments and reducing socioeconomic gaps in children's skills, but that simple informational policies may not be sufficient.

While behavioral non-price interventions ("nudges") have grown from academic curiosity to a bona fide policy tool, their relative economic efficiency remains under-researched. We develop a unified framework to estimate welfare effects of both nudges and taxes. We showcase our approach by creating a database of more than 300 carefully hand-coded point estimates of non-price and price interventions in the markets for cigarettes, influenza vaccinations, and household energy. While nudges are effective in changing behavior in all three markets, they are not necessarily the most efficient policy. We find that nudges are more efficient in the market for cigarettes, while taxes are more efficient in the energy market. For influenza vaccinations, optimal subsidies likely outperform nudges. Importantly, two key factors govern the difference in results across markets: i) an elasticity-weighted standard deviation of the behavioral bias, and ii) the magnitude of the average externality. Nudges dominate taxes whenever i) exceeds ii). Combining nudges and taxes does not always provide quantitatively significant improvements to implementing one policy tool alone.

An active area of research within the social sciences concerns the underlying motivation for sharing scarce resources and engaging in other pro-social actions. We develop a theoretical framework that sheds light on the developmental origins of social preferences by providing mechanisms through which parents transmit preferences for generosity to their children. Then, we conduct a field experiment with nearly 150 3-5 year old children and their parents, measuring (1) whether child and parent generosity is correlated, (2) whether children are influenced by their parents when making sharing decisions and (3) whether parents model generosity to children. We observe no correlation of independently measured parent and child sharing decisions at this young age. Yet, we find that apart from those choosing an equal allocation of resources between themselves and another child, children adjust their behaviors to narrow the gap with their parent's or other adult's choice. We find that fathers, and parents of initially generous children, increase their sharing when informed that their child will be shown their choice.

An active area of research within the social sciences concerns the underlying motivation for sharing resources and engaging in other pro-social actions. In this paper we ask: do parents model social preference behavior to children, and do children emulate this behavior? We develop a theoretical framework to examine this question, and conduct an experiment with 147 3 to 5 year old children and their parents, using dictator games to measure generosity. We find (1) evidence of parental teaching/modeling in the case of fathers and in that of parents of relatively generous children, and (2) an emulation effect such that children who initially share less than half of their endowment subsequently share more the more they see a parent or other adult share. We find little correlation between baseline sharing of children and the parents, with the possible exception of the oldest children.
