多主体模型下的银行网络流动性转移

Liquidity Transferring of Multi-Agent Model in Bank Networks

流动性危机是银行倒闭的重要原因,在金融危机形成和传染过程中起关键作用.银行网络流动性动态配置正是流动性危机形成的微观基础.因此,银行网络间流动性动态配置对于研究金融危机具有很强的现实意义.构建银行网络流动性转移的多主体模型可以模拟银行网络流动性再分配的过程,模拟结果表明银行网络结构、连接度都对网络流动性转移效率有重要影响.最后提出了基于这一模型给出了提高银行网络流动性转移效率的长效机制以及流动性危机的应急措施的政策建议.

The liquidity crisis is a major cause of bank failures and also plays a key role in leading to the formation and contagion of a financial crisis.In the meantime,the fundamental framework with which a liquidity crisis is developed is the dynamic liquidity configuration in the banking network.Therefore,the study and modeling of the dynamic liquidity configuration is of practical significance to the understanding and prevention of a financial crisis.A bank liquidity transferring multi-agent model based on networks is used to simulate the redistribution process of liquidity.Results indicate that both the network structure and the network connectivity have a significant influence on the liquidity transferring efficiency of the network.Finally,we put forth suggestions for emergency measures in the event of a liquidity crisis,as well as for long-term mechanisms to improve the liquidity transferring efficiency of a banking network.
