We present a neural network methodology for learning game-playing rules in general. Existing research suggests learning to find a Nash equilibrium in a new game is too difficult a task for a neural network, but says little about what it will do instead. We observe that a neural network trained...

Herding arises when an agents private information is swamped by public information in what Jackson and Kalai (1997) call a recurring game. The agent will fail to reveal his own information and will follow the actions of his predecessor and, as a result, useful information is lost, which might...

This paper examines experimental evidence relating to herd behaviour in situations when subjects can learn from each other, and can delay their decision. Subjects acted rationally, gaining from observational learning, despite penalties for delay. Cascades were ubiquitous and reverse-cascades...

The underlying motivations for envy or related social preferences and their impact on agricultural innovations are examined by combining data from money burning experimental game and household survey from Ethiopia.  In the first stage of the money burning experimental game, income inequality is...

Game harmony is a generic game property that describes how harmonious (non-conflictual) or disharmonious (conflictual) the interests of players are, as embodied in the payoffs. It can be used to predict cooperation in two-player games. We show how, for large enough positive harmony...

Three experiments on utility interdependence are discussed. Subjects receive money by betting and possibly by arbitrary assignments. They can then pay to reduce and, possibly, redistribute the steal money; in one case, only the decisions of a randomly determined dictator are implemented. The...

This paper presents the results of an experiment where people can reduce (`burn`) other subjects` money at a cost to their own, with the decisions of one of them (randomly chosen after all decisions are made) getting implemented to determine final winnings. Almost 50% of the subjects engage in...

A positive correlation between relative position and the neurotransmitter serotonin exists in non-human primates, within an optimal range. This paper explores the reasons of this correlation. The main function of serotonin appears cognitive: it determines how optimally agents perceive and behave...
