Evaluation of Technical Efficiency in Exotic Carp Polyculture in Northern India: Conventional DEA vs. Bootstrapping Methods

Abstract

The paper adopts the conventional data envelopment analysis (DEA) and bootstrap procedure to analyze the technical efficiency, while tobit regression is applied to identify the factors affecting efficiencies of exotic fish polyculture in Jammu and Kashmir (India). According to the statistical analysis of the variables utilized, there was a lot of variability in the inputs being used by the farmers, with the most variation being in the lime input. The DEA estimated technical efficiency for the sample farms in Jammu and Kashmir is 0.9771 and 0.9741, respectively, with least technical inefficiency of 3%. The bias-corrected (bootstrapped) technical efficiencies found were slightly lower than the ones estimated by conventional DEA. Mean allocative and cost efficiencies for sample farms in the Jammu region were 92% and 75%, respectively, and 84% and 74%, respectively, for farmers in the Kashmir region. Farming experience, age, and education have favorable impacts on technical efficiency of farmers in the state, but family size showed negative impacts. Efficiency improvement will eventually lead to increase in the production providing better scope for marketed surplus. More fisheries extension is suggested for expanding the exotic fish culture in the state making the enterprise a more profitable venture.

Determinant of Technical Efficiency of Sugarcane During the Covid 19 Pandemic in Malang Regency East Java Indonesia

“…The potential for increasing technical efficiency can be seen from the input savings that can be made by producers, in which sugarcane farmers in Malang Regency are advised to reduce inputs by 16.6% and 14.6%, on both assumptions for a double bootstrap approach. The more significant input savings in the DEA bootstrap approach were found in [17], [37] study. The findings of this study highlight the importance of using a double bootstrap approach in assessing technical efficiency, as this method uncovers greater potential for input savings and increased efficiency among sugarcane farmers in Malang District compared to conventional DEA methods.…”

Impacts of Elderly Population on the Technical Efficiency of Asean

“…In depth, the existing empirical studies also tend to focus on the nexus between aging and technical efficiency across the world. For the example, Zhang et al, (2022) statistically revealed that aging have favorable impacts on technical efficiency of farmers in Indian farmers. Furthermore, Saiyut et al (2019) also investigated the effect of age structure on technical efficiency in the context of agriculture in Thailand.…”

“…Similarly,Liu et al, (2019) also statistically proved that aging of teaproducing farmers would exert negative impacts on technical efficiency in tea production of Meitan, China. By contrast,Zhang et al, (2022) statistically revealed that aging have favorable impacts on technical efficiency of farmers in Indian farmers. Nevertheless,…”
