In this study, we examine the effectiveness of the individual-punishment mechanism in larger groups, comparing groups of four to groups of 40 participants. We find that the individual punishment mechanism is remarkably robust when the MPCR is held constant despite the coordination problems...

We examine the effectiveness of the individual-punishment mechanism in larger groups, comparing groups of four to groups of 40 participants. We find that the individual punishment mechanism is remarkably robust when the marginal per capita return (MPCR), i.e. the return to each participant from...

Brenner and Vriend (2006) argued (experimentally and theoretically) that one should not expect proposers in ultimatum games to learn to converge to the subgame perfect Nash equilibrium offer, as finding the optimal offer is a hard learning problem for (boundedly-rational) proposers. In this...

Using the parallel concepts and methods on the granular rod's spontaneous motion (PRL 106, 118001, 2011 [1]), in the observable (relative angular momentum) of the laboratory social evolution processes around the Nash equilibrium in the strategy space, we evaluate the large-deviation function...

The evolution equation determines how frequencies of strategies in the population change (Traulsen & Hauert (2009)), where the change indicates velocities (Bowles (2004),Weibull (1997),Sigmund (2010)). In this paper, based on the laboratory Rock-Paper-Scissors (RPS) game experiments and from the...

How to examine a behavior model in social computation is a long existed problem. By data mining, characters of the fluctuation in human subjects iterated prisoner’s dilemma (IPD) experiment are studied. Fluctuation is the individual strategy changing. In IPD, fluctuation of a population is the...
