A Study of Dairy Farm Technical Efficiency Using Meta-Regression: An International Perspective

This paper develops a meta-regression analysis to explain the variation of mean technical efficiency (PETP) measurements from a total of 65 frontier studies that report technical efficiency (ET) measurements at the dairy farm level in the literature published in English and Spanish. The analysis inc...
