Game Analysis of Investment in a Group with Stickiness

This paper studies the investment in a group with stickiness. A group investment game is constructed. By analyzing the best response of each player, the equilibria are presented. Furthermore, the convergence region of each equilibrium is outlined, and the sensitivity analysis of the region to parameters is explored. The game with two players is given to illustrate the convergence region of each equilibrium. The explanation and illustration of the results are summarized. The findings indicate that a successful investment usually occurs in a group with ‘tolerance’, ‘open‐sharing’, ‘efficiency’, ‘sensitivity’, and with large members.
