金融道德风险影响下银行贷款上限的决策研究

摘要

以中小企业融资困难为现实背景,基于报童模型,研究了银行面对有需求风险和金融道德风险的零售商时,如何给出最优的贷款上限以降低潜在的违约损失,以及缺乏运营资金的零售商如何优化订货决策和信贷决策.结论表明了零售商是否提出贷款要求、银行是否批准取决于市场上金融道德风险;而金融道德风险是否会真正转化为行动,则取决于该行为的实施成本.%The model describes and tries to provide solutions to the difficulty that small enterprises have when they ask for financing help from the bank.It combines Newsvendor model and financial moral hazard,and researches how the bank should decide credit limit when it is unclear whether the borrower has moral hazard or not.The conclusion clarified that the bank's decisions and the retailer's actions depend on the financial moral risk level on the whole market,and whether or not the retailer will jeopardize the bank through diverting the loan is affected by the implementing cost.
