Abstract

We propose “Rip-off”, a new multi-player bargaining game based on the well-studied weighted voting game (WVG) model from cooperative game theory. Many different solution concepts, such as the Core and the Shapley value have been proposed to analyze models such as WVGs. However, there is little work on analyzing how humans actually play in such settings. We conducted several experiments where we let humans play “Rip-off”. Our analysis reveals that although solutions of games played by humans do suffer from certain biases, a player’s average payoff over several games is roughly reflected by the Shapley value.
