Abstract

Though enormous researcher were conducted their study on economic efficiency in crop production, they found significant differences in mean economic efficiency scores and sign of important explanatory variables. Thus, this study aimed at determining the sources of differences in the overall mean economic efficiency estimates among crop production studies in Ethiopia using a meta-regression analysis based on 19 studies published from 2005-2019. The result of descriptive statistics revealed a significant inefficiency in crop production in the country. Accordingly, the overall average technical, allocative and economic efficiencies of reviewed empirical studies were 76%, 61% and 47% percent, respectively, indicating available prospects in enhancing economic efficiency in crop production in Ethiopia. Consequently, it also implies that output can be increased by 24 percent or cost can be reduced by 53 percent given the existing level of technology and resources. The econometrics results of meta-analysis also pointed out that out of twelve independent variables incorporated in the Tobit model method of efficiency estimation, number of independent variables, mean technical efficiency score, mean allocative efficiency score, type of model, method of efficiency estimation and dummy 2015 were found to affect mean economic efficiency of empirical studies positively and significantly where as type of crops, functional form and number of inputs were found to affect it negatively and significantly. Thus, there were a room to decrease variation among mean economic efficiency estimates if researches and academicians set out strategies directed towards the above mentioned causes of variations. Besides, this paper determines the causes of variations for economic efficiency in crop production only. Thus, it further call up other researchers and academicians to made further analysis on economic efficiency of agricultural production as a whole covering large number of studies and wide geographic areas.
