Testing the hypothesis of equal relative economic efficiency using restricted Aitken's least squares estimation
用受限艾特肯最小二乘法检验印度南部种植高产水稻品种的农民群体间是否具有相同的相对经济效率，发现大农户和小农户的经济效率相同。
This paper tests the hypothesis of equal relative economic efficiency between farmer groups growing high yielding paddy varieties (HYVs) in a Southern Indian district. Using a theoretically acceptable form of analysis, this work applies restricted Aitken's least squares method with Lagrange multipliers for the empirical verification of the hypothesis. This method of estimation provides an easier way of testing the hypothesis and a more useful interpretation of the results than the conventional method of analysis. The result of the study shows that large and small farmer groups are equally efficient economically in the production of high‐yielding paddy varieties.
