Information Protocol Equilibrium in n-insider Perfect Competition with a Random Deadline

引用

Acta Mathematicae Applicatae Sinica 2024年

作者： Qi-hong NIE Ji-xiu QIU Ji-ze LI yong-hui zhou School of Big Data and Computer Sciences Guizhou Normal University School of Mathematical Sciences Guizhou Normal University

This paper studies a model of n insiders with perfect information trading on a risky asset with value normally distributed and disclosed at a random deadline. We propose a concept of information protocol equilibrium under semi-strong efficient pricing, consisting of an n-profile of insider trading strategies with terminal residual information protocols, and find that if a common protocol on terminal residual information before trading is obeyed by all insiders, then, in the market with more than two insiders there exists a uique equilibrium only when it requires to release common partial information eventually, or it does not exist if it requires to release all or not any; but in the market with a single insider, the insider may release all private information eventually to make a maximal profit. Thereby, the existence and uniqueness of information protocol equilibrium among n insiders are deduced. Finally, numerical results illustrate some market characteristics of equilibria with different information protocols required before trading.

消费中心和城市群都是我国重要的区域发展对象,两者之间联系紧密,互动性强。消费中心概念的引入,能够为现有城市群研究提供新视角。城市群作为消费(中心)城市群,能够促进区域消费经济大发展,体现出消费性质差异化、消费形式多样化、消费水平层级化、消费内容普遍化、消费中心化、消费联系性强、消费完整度高、消费文化认同度高等特征,具有消费集聚构建宏大消费场景、消费中心化汇集更多消费动能、消费极化提升区域消费发展层级、整合消费形成区域消费竞争力等多重机制。基于熵值法、Dagum基尼系数及其分解法、Kernel估计法的量化分析表明,各城市群消费中心发展水平总体上呈稳定上升趋势,但不同城市群发展差异大。总体基尼系数走势较为平缓,甚至呈缓慢下降的态势。需要强化体制机制建设,以(国际)消费中心(城市)建设推动城市群发展。
