We estimate individual risk attitudes using controlled experiments in the field in Denmark. The experiments were carried out across Denmark using a representative sample of 253 people between 19 and 75 years of age. Risk attitudes are estimated for various individuals differentiated by socio-demographic characteristics. Our results indicate that the average Dane is risk averse, and that risk neutrality is an inappropriate assumption to apply. We also find that risk attitudes vary significantly with respect to several important socio-demographic variables such as age and education. However, we do not find any effect of sex on risk attitudes. Copyright The editors of the "Scandinavian Journal of Economics" 2007 .

We design a model-based field experiment to estimate the nature and magnitude of workers' social preferences towards their employers. We hire 446 workers for a one-time task. Within worker, we vary (i) piece rates; (ii) whether the work has payoffs only for the worker, or also for the employer; and (iii) the return to the employer. We then introduce a surprise increase or decrease in pay ('gifts') from the employer. We find that workers have substantial baseline social preferences towards their employers, even in the absence of repeated-game incentives. Consistent with models of warm glow or social norms, but not of pure altruism, workers exert substantially more effort when their work is consequential to their employer, but are insensitive to the precise return to the employer. Turning to reciprocity, we find little evidence of a response to unexpected positive (or negative) gifts from the employer. Our structural estimates of the social preferences suggest that, if anything, positive reciprocity in response to monetary 'gifts' may be larger than negative reciprocity. We revisit the results of previous field experiments on gift exchange using our model and derive a one-parameter expression for the implied reciprocity in these experiments.

The purpose of this paper is to describe a test involving five different approaches to estimating the demand for a public good. The test was conducted in a setting which permitted a real collective choice and in which each subject was committed to actual payments when relevant. The results indicate that the well-known risk for misrepresentation of preferences in this context may have been exaggerated. The test would seem to encourage further work in the field of experimental economics.

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.

The main purpose of this article is to advance a set of conditions which demand-revealing mechanisms must pass in order to be politically acceptable for real-world applications and - to begin with - for real-world experiments. Without such non-laboratory experiments, real progress seems unlikely to take place in this field. So far, there are few indications that these conditions can be met with respect to the proposals made in the literature on public goods. One possible example of a mechanism that meets the ""acceptability"" conditions is given here. In addition, we present some comments as to why demand-revealing mechanisms constitute and important economic problem, a view which has recently been questioned.

The A/B testing approach invites promising early results that are unlikely to be realized in a larger setting. We argue that within the social sciences, a fundamentally different approach is needed; we call it option C thinking. Put simply, a twenty-first-century team of civil servants and social scientists should lead with experiments that anticipate likely causes of failure at scale, even if doing so requires more time, effort, and resources initially.

Despite its growth in other areas of economics,time series econometric methods have not been widespread in the area of environmental and resource economics. We illustrate one use of time series methods by examining the time path of US nitrogen oxide (NOx) emission data over the period 1900-1994. The analysis highlights that proper time series methods can aid in optimal regulatory policy as well as developing empirical verification of theories put forth to explain economic phenomena. In addition, several interesting results emerge. First, we find that the emissions series contains both a permanent and random component. Second, if one attributed all of the emissions reductions to regulatory policy, intervention analysis suggests that the 1970 Clean Air Act(CAA) did not merely have transitory effects,but permanently influenced the NOx emission path. In terms of total regulatory impact, an upper bound on the emissions saved due to the 1970 CAA is in the range of 27%-48%.

Expanding access to commercial credit is a key ingredient of financial development strategies. There is less consensus on whether expanding access to consumer credit helps borrowers, particularly when loans are extended at high interest rates. Popular skepticism about "unproductive," "usurious" lending is fueled by research highlighting behavioral biases that may induce overborrowing. We estimate the impacts of expanding access to consumer credit at a 200% annual percentage rate (APR) using a field experiment and follow-up data collection. The randomly assigned marginal loans produced significant net benefits for borrowers across a wide range of outcomes. There is also some evidence that the loans were profitable.

Despite increased use of experimental auctions, a myriad of different procedures are being employed without formal consideration of how the procedures might affect results. The study investigates the effect of several procedural issues on valuation estimates from experimental auctions. Results indicate the second price auction generates higher valuations than English, Becker-DeGroot-Marschak (BDM), and random nth price auctions, especially in latter bidding rounds, and that random nth price auction yields lower valuations than English and BDM auctions. We find that endowing subjects with a good prior to eliciting bids can have an impact on valuationsk, but the effect varies across auction mechanism.

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.

This review summarizes the historical place of the seminal contribution of Kahneman et al. (1990), from origins to theory to catalyst of an entire area of scholarship. This new literature has produced evidence both in concert with the original KKT conclusions as well as evidence refuting certain insights from KKT. The general theme of my summary is that even imperfect papers can have deep impact, both within and outside the academy; a lesson that today's critics should consider as young experimentalists continue to fight the tyranny of the top 5.

This paper revisits results from a field experiment conducted in Florence, Italy to study the effects of incentives offered to high school teens to motivate them to visit art museums and to identify best practices to transform this behavior into a long run cultural consumption. Students belonging to a first group of classes receive a flier with basic information and opening hours of a main museum in Florence, Palazzo Vecchio. Students in a second group of classes receive the flyer and a short presentation conducted by an art expert. Students in a third group of classes, in addition to the flyer and the presentation, receive also a nonfinancial reward in the form of extra-credit points towards their school grade. Taking a Principal Stratification approach, we explore the causal pathways that may lead students to increase their future museum attendance. Within the strata defined by compliance to the three forms of encouragement, we estimate associative and dissociative principal causal effects, that is, effects of the encouragement on the primary outcome, long run cultural consumption, that are associative or dissociative with respect to the effects of the encouragements on the Palazzo Vecchio visit. This analysis allows to interpret these effects as ascribable either to the encouragements, or to the museum visits, or to classroom spillovers. To face identification issues, estimation is performed with Bayesian inferential methods using hierarchical models to account for clustering. The main findings of the analysis are as follows: what seems to matter the most is the motivational incentive (i.e., the presentation), rather than the induced experience, i.e., the Palazzo Vecchio visit.

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.

We use a sample of subsistence farmers in Sierra Leone as respondents to compare behavior in a context-free experiment (a standard public goods game) and behavior in the field (a real development intervention). There is no meaningful correlation in behavior across contexts. This casts doubt on the prospect of using lab experiments as "predictors" of behavior in real life.

We experimentally investigate the effect of social identification and information feedback on individual behavior in contests. In all treatments we find significant over-expenditure of effort relative to the standard theoretical predictions. Identifying subjects through photo display decreases wasteful effort. Providing information feedback about others' effort does not affect the aggregate effort, but it decreases the heterogeneity of effort and significantly affects the dynamics of individual behavior. A behavioral model which incorporates a non-monetary utility of winning and relative payoff maximization explains significant over-expenditure of effort. It also suggests that decrease in 'social distance' between group members through social identification promotes pro-social behavior and decreases over-expenditure of effort, while improved information feedback decreases the heterogeneity of effort.
