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.

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.

This paper tests the empirical predictions of recent theories of the endogenous entry of bidders in auctions. Data come from a field experiment, involving sealed-bid auctions for collectible trading cards over the Internet. Manipulating the reserve prices in the auctions as an experimental treatment variable generates several results. First, observed participation behavior indicates that bidders consider their bid submission to be costly, and that bidder participation is indeed an endogenous decision. Second, the participation is more consistent with a mixed-strategy entry equilibrium than with a deterministic equilibrium. Third, the data reject the prediction that the profit- maximizing reserve price is greater than or equal to the auctioneer's salvage value for the good, showing instead that a zero reserve price provides higher expected profits in this case.

Firms spend billions of dollars annually on new product and label designs in order to attract and retain customers. The issue of labeling is also important to government agencies and nonprofit labeling organizations. For example, the U.S. Food and Drug Administration has an organizational body in its Office of Nutritional Products that deals with issues of food and dietary supplement labeling. The U.S. Department of Agriculture's Food Safety and Inspection Service also deals with labeling through its Labeling and Consumer Protection Staff. These government agencies spend millions of dollars trying to ensure that food labels adequately inform consumers. One issue that has not been examined is the welfare difference to consumers from alternative labeling schemes/regulations. It seems likely that different labels would differ in effectiveness at informing consumers.

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).

One conjecture in the theory of incentives is that incentives based on broader outcomes may be better at motivating agents than incentives based on narrow measures. We designed an experiment to test these hypotheses using a ""prospective randomized evaluation procedure"" (PREP). We then apply PREP to training programs as typically funded by donors of economic development assistance. We randomly assigned 274 participating entrepreneurs in the Philippines to one of 26, simultaneous, one-day, training classes in marketing. Trainers were given cash incentives based on the average score of their ""students"" on a standardized test containing an alternative number of questions, which were randomly assigned to each class. We then examined outcomes based on student satisfaction ratings of the trainer. Our results suggest that incentives based on broad outcomes are more effective than incentives based on narrow outcomes. We conclude with ways to improve our approach as well as with a discussion of the implications for using prospective randomized evaluation for improving the evaluation of donor projects.

Complementing proprietary archival data with an experiment, we examine employees' subjective valuations of their employee stock options and explore a stock option education program as a mechanism for influencing those valuations. We argue that the conflicting evidence on employee subjective valuations in prior studies can be attributed in part to knowledge differences. Our archival and experimental results show most employees value their options lower than the corresponding Black-Scholes cost. We find that a stock option education program that provides descriptive information about the Black-Scholes option pricing model and quantitative information about option values using that model increases not only employees' subjective valuations but also their self-reported loyalty and motivation. We complement our primary results with analyses of the cross-sectional determinants of subjective valuations, the differential effects on valuations of different components of the education program, and the heuristics used to formulate subjective valuations.

We conduct a framed field experiment in a Dutch university to compare student effort provision and exam performance under the two most prevalent evaluation practices: absolute (criterion-referenced) and relative (norm-referenced) grading. Based on the empirical stylized fact of gender differences in competitiveness we hypothesize that the rank-order tournament created by relative grading will increase male, but not female, performance. Contrary to our expectations, we find no impact of competitive grading on preparation behavior or exam scores among either gender. Our result may be attributed to the low value students in our sample attach to academic excellence.

Research on behavioral economics has established the importance of factors such as reference dependent preferences, hyperbolic preferences, and the value placed on non-financial rewards. To date, these insights have had little impact on the way the educational system operates. Through a series of field experiments involving thousands of primary and secondary school students, we demonstrate the power of behavioral economics to influence educational performance. Several insights emerge. First, we find that incentives framed as losses have more robust effects than comparable incentives framed as gains. Second, we find that non-financial incentives are considerably more cost-effective than financial incentives for younger students, but were not effective with older students. Finally, and perhaps most importantly, consistent with hyperbolic discounting, all motivating power of the incentives vanishes when rewards are handed out with a delay. Since the rewards to educational investment virtually always come with a delay, our results suggest that the current set of incentives may lead to under-investment. For policymakers, our findings imply that in the absence of immediate incentives, many students put forth low effort on standardized tests, which may create biases in measures of student ability, teacher value added, school quality, and achievement gaps.

Does willingness to aid "others" change when in their physical presence? We argue that studies cueing non-coethnics through names and photos may underestimate discrimination resulting from actual interethnic interaction. In an experiment in Kabul, Afghanistan, Dari-speaking day-laborers contribute their earnings to a hospital under one of three randomly-assigned experimental conditions. In In-group, the hospital is in a Dari-speaking province; in Out-group-Abstract and Out-group-Real, it is in a Pashto-speaking (Pashtun) province. While subjects in In-group and Outgroup- Abstract wait for the experiment with only Dari-speakers present, subjects in Out-group-Real wait among both Dari-speakers and Pashto-speakers. When Pashtuns are absent, the findings accord with other experiments that find little to no out-group discrimination. However, the physical presence of Pashtuns (Out-group-Real) decreases contributions by 25%. Consistent with the threat hypothesis, contributions decrease the longer Dari-speakers wait with Pashtuns, though subjects' youth and ability to speak Pashto mediate this effect.

The experimental literature has shown the tendency for experimental trading markets to converge to neoclassical predictions. Yet, the extent to which theory explains the equilibrating forces in markets remains under-researched, especially in the developing world. We set up a laboratory in 94 villages in rural Sierra Leone to mimic a real market. We implement several treatments, varying trading partners and the anonymity of trading. We find that when trading with co-villagers average efficiency is somewhat lower than predicted by theory (and observed in different contexts), and markets do not fully converge to theoretical predictions across rounds of trading. When participants trade with strangers efficiency is reduced more. Anonymizing trade within the village does not affect efficiency. This points to the importance of behavioral norms for trade. Intra-village social relationships or hierarchies, instead, appear less important as determinants of trading outcomes. This is confirmed by analysis of the trader-level data, showing that individual earnings in the experiment do not vary with one's status or position in local networks.

Economic analyses of asymmetric information typically start with the assumption that individuals know more about their own characteristics than outside observers. This assumption implies that individuals can accurately assess their own competence in a given domain. However, individuals can only judge their competence if they are sufficiently competent. The relationship between competence and self-awareness explains a great deal of the overconfidence observed among economic agents. More specifically, overconfidence is inversely proportional to competence. Through a series of experiments and analyses of field data, the link between incompetence and overconfidence is confirmed and its implications for economic theory are explored.

Ambiguity about the chances of winning represents a key aspect in lotteries. By means of a controlled field experiment, we exogenously vary the degree of ambiguity about the winning chances of lotteries organized to incentivize the contribution for a public good. In one treatment, people have been simply informed about the maximum number of potential participants (i.e. the number of lottery tickets released). In a second treatment, this information has been omitted as in all traditional lotteries. Our general finding shows that simply reducing the degree of ambiguity of the lottery leads to a sizable and significant increase (67%) in the participation rate. This result is robust to alternative prize configurations.

Using a sample of CCIM designees and candidates in an experimental setting, this study examines the impact of broker signaling in commercial real estate transactions. It also explores the effect of certainty of closure in commercial real estate transactions. Findings suggest brokers are able to influence transaction pricing. Moreover, detailed analysis reveals that when a signal is above a reference point implied by previous transactions, the strength of the signal matters; privately communicated signals from reliable sources have significantly greater impact than signals which are made widely available. Additionally, we find an approximately 10% premium in transactions with lower certainty of closure than one with high certainty. The latter result varies by transactional participant type; owner/developers require a larger premium than institutional sellers.

We test the disjunctive hypothesis as it relates to mortgage contracts and find that a liquidated damages clause shifts one's view of a mortgage from a promise to perform to either a promise to perform or pay compensatory damages. However, when a strategic mortgage default is responsible for the breach, the perceived immorality of this action overwhelms the liquidated damages clause effect in support of the disjunctive thesis. We also find that people's conscious "experimentally stated preference" moral stance on installment loan (mortgages, auto loans, credit card debt and even cell phone contracts) default significantly differs from their subconscious "experimentally revealed preference" moral stance indicating a difference between what people say they believe and what they actually believe.

We investigate whether customers' overall impression of online property listings can be influenced by the real estate agent, and whether this influence depends on the customer's demographic characteristics. A sample of 1,594 potential homebuyers took an online audio/visual tour of a typically priced home in their area. Subjects were shown one of eight conditions in which we varied agent gender (male/female), agent attractiveness (attractive/less attractive), and pathos (used/not used). The results show that segments of customers are drawn to different real estate agents, but contrary to our expectations, customers were not necessarily drawn to similar agents or more attractive ones.
