We consider a prediction market in which traders have heterogeneous prior beliefs in probabilities. In the two-state case, we derive necessary and sufficient conditions so that the prediction market is accurate in the sense that the equilibrium state price equals the mean probabilities of...

Despite advances in the field, we still know little about the socio-cognitive processes of team decisions, particularly their emergence from an individual level and transition to a team level. This study investigates team decision processes by using an agent-based model to conceptualize team...

The paper investigates the minimum level of individual rationality that is needed for market prices to converge toward their equilibrium level. It does so by examining the theoretical and methodological foundations of the 'zero-intelligence' (ZI) agent trading approach, with which Gode and...
