Active decisions and pro-social behavior
In this paper, we propose a decision framework where people are individually asked to either actively consent to or dissent from some pro-social behavior. We hypothesize that confronting individuals with the choice of whether to engage 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 donations. We find that this ?active-decision? intervention substantially increases the actual donation behavior of people who had not fully ...

Games with synergistic preferences
In economic situations a player often has preferences regarding not only his or her own outcome but also regarding what happens to fellow players, concerns that are entirely apart from any strategic considerations. While this can be modeled directly by simply writing down a player's final preferences, these are commonly unknown a priori. In many cases it is therefore both helpful and instructive to explicitly model these interactions. This paper, building on a model due to Bergstrom (1989, 1999), presents a simple structure in the context of game theory that incorporates the "synergies" ...

Estimating a structural model of herd behavior in financial markets
We develop a new methodology for estimating the importance of herd behavior in financial markets. Specifically, we build a structural model of informational herding that can be estimated with financial transaction data. In the model, rational herding arises because of information-event uncertainty. We estimate the model using 1995 stock market data for Ashland Inc., a company listed on the New York Stock Exchange. Herding occurs often and is particularly pervasive on certain days. In an information-event day, on average, 2 percent (4 percent) of informed traders herd-buy (sell). In 7 percent ...

The empirical content of models with multiple equilibria in economies with social interactions
We study a general class of models with social interactions that might display multiple equilibria. We propose an estimation procedure for these models and evaluate its efficiency and computational feasibility relative to different approaches taken to the curse of dimensionality implied by the multiplicity. Using data on smoking among teenagers, we implement the proposed estimation procedure to understand how group interactions affect health-related choices. We find that interaction effects are strong both at the school level and at the smaller friends-network level. Multiplicity of ...

Public and private values
This paper experimentally examines whether looking at other people's pricing decisions is a type of heuristic - a decisionmaking rule - that people use even when it is not applicable, as in the case of clearly private value goods. We find evidence that this is indeed the case - an individual's valuation of a purely subjective experience under full information, elicited using an incentive compatible mechanism, is highly influence by valuations made by others. This result can shed light on price behavior, price rigidities, and rents.

Managing self-confidence: theory and experimental evidence
Evidence from social psychology suggests that agents process information about their own ability in a biased manner. This evidence has motivated exciting research in behavioral economics, but also garnered critics who point out that it is potentially consistent with standard Bayesian updating. We implement a direct experimental test. We study a large sample of 656 undergraduate students, tracking the evolution of their beliefs about their own relative performance on an IQ test as they receive noisy feedback from a known data-generating process. Our design lets us repeatedly measure the ...

Do people behave in experiments as in the field?: evidence from donations
Laboratory experiments are an important methodology in economics, especially in the field of behavioral economics. However, it is still debated to what extent results from laboratory experiments can be applied to field settings. One highly important question with respect to the external validity of experiments is whether individuals act the same in experiments as they would in the field. ; This paper presents evidence on how individuals behave in donation experiments and how the same individuals behave in a naturally occurring decision situation on charitable giving. The results show that ...

Another hidden cost of incentives: the detrimental effect on norm enforcement
Monetary incentives are often considered as a way to foster contributions to public goods in society and firms. This paper investigates experimentally the effect of monetary incentives in the presence of a norm enforcement mechanism. Norm enforcement through peer punishment has been shown to be effective in raising contributions by itself. We test whether and how monetary incentives interact with punishment and how this in turn affects contributions. Our main findings are that free riders are punished less harshly in the treatment with incentives, and as a consequence, average contributions ...

Predicting health behaviors with economic preferences and perceived control
We present new evidence on the relationship between health behaviors and experimental measures of risk and time preferences and introduce evidence that perceived control ? a measure incorporated from the health psychology literature ? is a stronger and more consistent predictor of health behaviors than economic preferences.
