Many psychology experiments show that individually judged probabilities of the same event can vary depending on the partition of the state space (a framing effect called "partitiondependence"). We show that these biases transfer to competitive prediction markets in which multiple informed traders are provided economic incentives to bet on their beliefs about events. We report results of a short...

This paper investigates a discrete-time system with Markov modulated batch Bernoulli process (MMBP) inputs, general service times, and a finite capacity waiting room (queue). The FIFa and space priority service rules are considered. The main motivation for studying this type of queue is its potential applicability to time-slotted communication systems in broadband ISDN (B-ISDN). Applying the su...

The results of recent studies on prediction markets are encouraging. Prior experience demonstrates that markets with different incentive schemes predicted uncertain future events at a remarkable accuracy. In this paper, we study the impact of different monetary incentives on the prediction accuracy in a field experiment. In order to do so, we compare three groups of users, corresponding to thre...

In 2026, the FIFA World Cup will for first time gather 48 men’s national teams. It consist of a group stage made 16 groups three, with best two teams in each advancing to knockout stage. Using three raises several fairness issues, including risk match fixing and schedule imbalance. this article we examine collusion. The who play last game know exactly what results let them advance Risk occurs w...
