Intermediation Costs in an Agricultural Development Bank: A Cost‐Function Approach to Measuring Scale Economies
用超越对数模型分析洪都拉斯农业发展银行的成本与产出关系，发现平均分支机构的规模经济不显著，贷款业务规模报酬接近常数，但存款动员仍有未开发的规模经济，且联合提供存贷服务比传统专业放贷更有优势。
Abstract The cost‐output relationships and production technology in the Agricultural Development Bank of Honduras are analyzed using a translog model. Scale economies for the average branch are not significantly different from one. They are a function of output levels reflecting U‐shaped cost surfaces. Product‐specific economies of scale are substantially different. Returns to scale of lending activities approach unity, whereas there are important unexploited economies to the expansion of deposit mobilization. Cost complementarities between lending and deposit mobilization indicate advantages of joint provision of financial services over the traditional specialization in lending of agricultural development banks in developing countries.
