An application and test for a random coefficient model in Bangladesh agriculture
估计孟加拉国四个地区的生产函数，发现随机系数法优于OLS，并通过分段回归揭示小农场效率更高。
Abstract This paper deals with efficiency question by estimating four production functions for four different regions in connection with Bangladesh agriculture. Hildreth and Houck's (1968) random coefficient method was found more suitable than OLS after conducting an appropriate test for this. In contrast to earlier studies, 24 piece‐wise regressions have been fitted for each index of efficiency considering all four regions and six different ranges of farm size instead of a single regression so that the relationship could be studied more closely. The study clearly indicates higher efficiency for smaller farms.
