本文对日本财产意外保险公司的规模经济和范围经济进行了检验。我们对1980年至1995年期间的一组日本公司拟合了一个复合成本函数,并采用了一个误差分量模型。我们的主要发现如下。首先,在日本经营的日本公司和外国公司都观察到了统计上显著的规模经济。其次,对日本公司和大多数外国保险公司来说,“第三部门”产品和其他财产意外险之间的范围经济在统计上也很重要。《风险与保险杂志》版权所有。
This article tests economies of scale and economies of scope for the property-casualty insurance companies in Japan. We fit a composite cost function to a set of Japanese firms over the period from 1980 to 1995 and employ an error components model. Our main findings are as follows. First, statistically significant economies of scale are observed in both Japanese firms and foreign firms operating in Japan. Second, economies of scope are also statistically significant for Japanese firms and most of the foreign insurers between the "third sector" products and the rest of the property-casualty insurance lines.
