Bank Capital,Bank Loan and Macroeconomic Fluctuation
通过引入存贷比要求、信用风险和可变风险权重扩展C-C模型，研究银行资本、贷款与宏观经济波动的关系，发现存贷比和信用风险加剧了巴塞尔I下银行资本和贷款的顺周期性，而巴塞尔II的可变风险权重可部分缓解这一效应。
In the context of the implement of Chinese New Capital Accord,this paper studies the relationship among bank capital,bank loan and macroeconomic fluctuation by introducing loan-to-deposit ratio requirement, credit risk and variable risk weight to extend the basic C-C model in the three aspects.Based on this new theory framework,we firstly compare the optimal behaviors of the representative bank under the binding regulatory capital requirement(B-CR) and non-binding(NB-CR) both in the BaselⅠand BaselⅡframeworks.Secondly,we prove how the fluctuation of macroeconomic impacts the optimal behaviors of the banks.Finally,we indicate clearly that the loan-to-deposit ratio requirement and credit risk doubly strengthen the procyclicality of bank loan and bank capital in BaselⅠ.However,the variable risk weight of BaselⅡmay weaken the procyclicality of capital requirement in certain extent.
