I conduct an experiment to assess whether majority voting on a nonbindingsharing norm affects subsequent behavior in a dictator game. Ina baseline treatment, subjects play a one shot dictator game. In a votingtreatment, subjects are first placed behind a ‘veil of ignorance’ and vote onthe...

Economics has devoted little attention so far as to whether the type of decision maker matters for economic decisions. However, many important decisions like those on monetary policy or a company’s business strategy are made by (small) groups rather than an individual. We compare behaviour of...

We test for behavioral differences between groups and individuals in gift-exchange experiments. Related studies establish group behavior as typically closer to the game-theoretic equilibrium. We show that this result my depend crucially on the decision making procedure within groups. A novel...

Few micro…nance-funded businesses grow beyond subsistence entrepreneur-ship. This paper considers one possible explanation: that the structure ofexisting micro…nance contracts may discourage risky but high-expected returninvestments. To explore this possibility, I develop a theory that uni…es...

This article examines the nature of human behavior in a nested socialdilemma referred to as the Spillover Game. Players are divided into twogroups with positive production interdependencies. Based on theoreticallyderived opportunistic, local, and global optima, our experimental...

E-nstructions facilitates the use of electronic instructions in computerized laboratory ex-periments in social sciences. In this article I provide a set of guidelines for the installationand the use of E-nstructions.

Based on an experimental analysis of a simple monetary economy we argue that a monetary system is more stable than one would expect from individual rationality. Weshow that positive reciprocity stabilizes the monetary system, provided everyparticipant considers accepting money as a reasonable...

This paper contributes to the micro-foundation of money in centralizedmarkets with idiosyncratic uncertainty. It shows existence of stationarymonetary equilibria and ensures that there is an optimum quantity ofmoney. The rational solution of our model is compared with actual be-havior in a...

We explain excess volatility, short-term momentum and long-term reversal of asset prices by a repeated game version of Keynes beauty contest. In every period the players can either place a buy or sell order on the asset market. The actual price movement is determined by average market orders and...

Charness et al. (2007b) have shown that group membership has a strong effect on individualdecisions in strategic games when group membership is salient through payoff commonality.In this comment I show that their findings also apply to non-strategic decisions, even when nooutgroup exists, and I...
