Abstract
The study employed a corrected ordinary least square and maximum likelihood estimate approach to find the technical efficiency of the production of rice in the Cauvery delta zone of Tamil Nadu. The data collected for two years (2009-10 and 2010-11) under the Cost of Cultivation Scheme of Tamil Nadu Centre were used for the study. The results of OLS and MLE of technical efficiencies were compared. The result showed that 97% of farmers having their technical efficiency above 0.5 in maximum likelihood estimates but 88% of farmers were falls in this range in Corrected OLS estimates. The output oriented mean technical efficiency was found to be 81% in maximum likelihood estimates whereas 86% corrected OLS estimates. This shows that Maximum likelihood estimates are more consistent over corrected OLS estimates.
