It is difficult to identify acts that are purely altruistic, and do not have some level of egoism or self-interest involved. By considering situations where team members seemingly have nothing to gain by the way they distribute points to others with regard to peer evaluation, and where their...

There is a substantial literature examining coordination in public goods games. We conducted an experiment to explore how varying patterns of thresholds affect the willingness of subjects to contribute to a public good. We had subjects play a multi-period game where each subject was allocated an...

In an experiment using two-bidder first-price sealed bid auctions with symmetric independent private values, we collected information on the female participants' menstrual cycles. We find that women bid significantly higher than men in their menstrual and premenstrual phase but do not bid...

In an experiment using two-bidder first-price sealed bid auctions with symmetric independent private values, we scan also the right hand of each subject. We study how the ratio of the length of the index and ring fingers (2D:4D) of the right hand, a measure of prenatal hormone exposure, is...

In this paper we analyse the empirical performance of several preference functionals using individual and group data. Our investigation aims to address two fundamental questions that have, until now, not been addressed in literature. Specifically, we intend to assess if there exists a risky...

101 real couples participated in a controlled experimental risk taking task involving variations in household and individuals’ income risks, but controlling for ex-ante income inequal- ity. Our design disentangles the effect of household risk, of intra-household risk inequality and of ex-post...

In the real life groups, rather than individuals, take the most part of decisions. So that it is useful to study how groups take a decision in different strategic environments. This paper provides an overview of previous research about groups’ preferences over risk. I compare different...

We present results from an experiment with a within-subject design aimed at testing a unique prediction of expectations-based reference-dependent preferences and loss aversion in private-value second-price (Vickrey) auctions. If bidders have expectationsbased reference-dependent preferences, the...
