题目: 基于变分不等式的网络竞赛的研究

TitleNetworks in Conflict: A Variational Inequality Approach

主讲人:徐进

Presenter:Jin Xu

Abstract

本文研究了一个网络上的竞赛博弈,证明了Nash均衡集的非空性和凸性且使用变分不等式提供了等价的刻画,并展示了成本函数的强单调性可保证均衡的唯一性。另外,本文还考查了模型参数如何影响均衡努力和收益,讨论了奖励分配、竞赛设计等应用。

We study a contest game among players fighting in a nexus of conflicts. We show that the set of pure strategy Nash equilibria is nonempty and convex, and provide equivalent characterizations using techniques from Variational Inequality (VI). We illustrate that strong monotonicity of cost functions always implies uniqueness of equilibrium regardless of the structure of conflict. Moreover, we conduct extensive comparative statics analysis with respect to the parameters of the model on equilibrium efforts and payoffs, and discuss several applications in terms of prize allocation and contest design.
