A Theoretical Analysis on Efficiency of a Narrow Bank System

本研究的目的是通过构建一个理论模型来严格分析骨髓银行制度的效率。目前的银行体系建立在部分准备金制度的基础上，存在内在的不稳定性，担心银行资产负债表的资产端和负债端的流动性不匹配。近年来，随着银行构建以先进信息技术为基础的网络系统，整个银行体系的不稳定性问题被频繁地争论。当银行陷入困境时，通常会指出银行的公共性。特别是，银行网络作为经济的支付系统，一家银行的倒闭会立即影响到其他银行，进而影响到整个支付系统。这一机制证实了当局对银行系统的干预。然而，对于合适的干预形式，我们没有任何共识。这种亟待解决的问题引发了这一研究。研究的结果之一是，狭义银行制度在资源配置效率方面是合适的，这与通常的理解相反。这项研究还提出了银行监管的理想形式。

The purpose of this research is to analyze the efficiency of the marrow bank system rigorously by constructing a theoretical model.The curried banking system which is based on a partial reserve system has intrinsic inside instability dread abad match of liquidity between the asset side and liability side of the balance sheet of banks. Recently instability of the whole banking system has been argued frequently as banks are constricting a net work system based on advanced information technology.The public nature of banks is usually pointed out when banks are in trouble. Especially, the network of banks works as a payment system of the economy and the failure of one bank affects other banks instantly, which in turn affects the whole payment system. This mechanism validates the intervention of authorities into the banking system. However, we do not have any consensus on the suitable form of intervention. This kind of issue awaiting solution initigates this research.One of the results obtained is that the narrow bank system is suitable regarding the efficiency of resource allocation contrary to usual understanding. This research also suggests the desirable form of banking regulation.
