Abstract

Technical efficiency (TE) measures the ability of the farmers to obtain maximum output from a given combination of inputs. This paper aims to examine the determinants of technical efficiency (TE) in shrimp culture in Pulicat area of Tamil Nadu in India. A stochastic production frontier model to estimate technical efficiency was applied to samples of intensive farms interviewed during 2019. The TE ranges between 0.16 to 0.99 with the mean technical efficiency of 0.9 and it implies that the shrimp farmers can reach full technical efficiency by reducing their input by another 10%. Findings revealed that less than 25% of the shrimp farmers sampled have technical efficiency scores less than 0.80. Feed and manure & chemicals have been found as important determinants of TE. Results indicated that experience, education, family size and risk-bearing ability have a significant impact on technical efficiency.
