Technical Efficiency of Agricultural Production in Ethiopia

Abstract

Farmers faced low productivity due to lack of knowledge on maximizing level of output at the given level of inputs. Technical efficiency of agricultural production in the Ethiopia were assessed by using cross-sectional secondary data collected from Ethiopia socioeconomic survey in 2015/16 production year. Cobb-Douglas stochastic frontier production function model was used to estimate technology and determinants of technical inefficiency simultaneously using the maximum likelihood estimator (MLN). MLN estimation results showed that increasing input use like area, seed, oxen, fertilizer and labor would increase yield of agricultural production. The coefficients of elasticity for area, seed, oxen, fertilizer and labor were 0.21, 0.29, 0.38, 0.12 and 0.10 respectively. Consequently, agricultural production exhibits increasing return to scale because the sums of input elasticity’s were greater than one which is 1.1. The mean technical efficiency of farmers in the agricultural production was about 36%. The implication is that there is an opportunity to increase output on average by 64% through efficient use of inputs given the current input use and technology. The discrepancy ratio gamma (γ) which measures the relative deviation of output from the frontier due to inefficiency was about 86 percent indicating that about 86% of variation in agricultural production among the farmers was attributed to technical inefficiency effects. Thus, it is possible to improve technical efficiency through better use of these factors.
