We explore the effects of social distance on reciprocal behavior in an experiment conducted over the Internet on three continents and in classroom laboratory sessions conducted in Israel and Spain.

Empirically, mutual fund flows depend on past performance. It is unclear, however, whether this behavior is rational. Using the experimental approach we analyze behavior without confronting measurement problems of real data. We detect two anomalies: quot;Absolute Performance Effectquot; --...

The field experimental approach was utilized to collect expectations-arbitrage portfolios from competent investors in late 2008 where stock prices shrunk by 50%. Positions were closed after three months and the four-factor model was applied to characterize strategies and derive risk-adjusted...

We compare the standard one-bid first price auction to a corresponding two-bid first price auction where each buyer may place two bids: a high bid and a low one and the winner pays his low bid if this was higher than all other bids. We characterize the equilibria of the two mechanisms and prove...

Assume that two risk neutral agents with asymmetric information simultaneously expect a gain from zero-sum betting. Geanakoplos and Sebenius (1983) (henceforth GS) consider the case where the agents may re-evaluate the profitability of betting successively before the payments are realized. They...
