The Nonparametric Risk‐Adjusted Efficiency Measurement: An Application to Taiwan's Major Rural Financial Intermediaries
用非参数方法将风险纳入技术效率测量，以台湾农村金融中介为案例，发现不良贷款、贷款损失准备金和风险资产三种风险约束均有效，其中风险资产和贷款损失准备金监管负担更重。
Abstract In this article, a nonparametric approach is used to incorporate risk into the measurement of technical efficiencies of the major financial intermediaries in rural Taiwan. Risk is treated as a joint but undesirable output given the fact that various regulatory actions may prevent its free disposability. Three risk indicators (nonperforming loans, allowance for loan losses, and risky assets) are employed alternatively in the empirical work. Results suggest that all three risk constraints are binding. Regulations on controlling risky assets and loan loss reserves are effective but more burdensome than those on controlling loan quality.
