We conducted an experiment to describe how social learners use information about the relation between payoffs and behavior. Players chose between two technologies repeatedly. Payoffs were random, but one technology was better because its expected payoff was higher. Players were divided into two...

We provide the first systematic empirical analysis of how asymmetric information and competition in the credit market affect voluntary information sharing between lenders. We study an experimental credit market in which information sharing can help lenders to distinguish good borrowers from bad...

Economists long considered money illusion to be largely irrelevant. Here we show, however, that money illusion has powerful effects on equilibrium selection. If we represent payoffs in nominal terms, choices converge to the Pareto inefficient equilibrium; however, if we lift the veil of money by...

We suggest a new micro-foundation of money in which markets are well-organized but consumers' preferences are stochastic. In this model, we solve for stationary equilibria and show that there is an optimum quantity of money. The rational solution of our model is compared with actual behavior in...

In the television show Deal or No Deal an individual faces a sequence of binary choices between a risky lottery with equiprobable prizes of up to half a million euros and a monetary amount for certain. The decisions of 348 contestants from Italian and British versions of the show are used to...

Cross-disciplinary 'happiness research' has made big progress in the measurement of individual welfare. This development makes it tempting to pursue the old dream of maximizing aggregate happiness as a social welfare function. However, we postulate that the appropriate approach is not to...

In this paper we analyze the long-run dynamics of the market selection process among simple trading strategies in an incomplete asset market with endogenous prices. We identify a unique surviving financial trading strategy. Investors following this strategy asymptotically gather total market...
