Meta-regression Analysis of Technical (In)Efficiency in Agriculture: a Regional Approach

While scientific studies have not reached a consensus on the methodology for examining Technical Efficiency (or Inefficiency), influence of regions appears to be important efficiency scores. Therefore, this research aims investigate empirical procedures achievement more robust results in analysis productive efficiency, as well evaluate effect location farms such efficiency. The goal was check whether most developed are efficient. Meta-regression provides an adequate method accurate assessment both situations. This technique applied based database 166 observations agricultural sector from countries around world, published period 2010–2017. criteria used collection and conceived model were previously and, thereby, enrich discussion topic. procedure variation Mean Inefficiency conduct using Quasi-Maximum Likelihood Estimation. regressions showed that could mainly explained by data, variables, employed models region study. focus present lowest Inefficiency, while developing or low-income exhibit opposite. future analysis, we suggest aimed at achieving take into account specific regional characteristics farms.
