Dynamical Pattern in a 2 × 2 Game with Human Subjects (Chinese)

Abstract

In the two-dimensions’ strategy space of a two-populations society, social should be jumping or stop at each moment. From a 2 × 2 game of experimental economics laboratory data, we measure the mean velocity of the jumping at each point of the strategy space. We find that the velocity vector field is in a cycle pattern, at the same time, unbalanced (beyond detailed balance condition) jumping’s distribution is in a ring-mountain form.
