A Study of Dairy Farm Technical Efficiency Using Meta-Regression: An International Perspective Chilean J. Agric. Res.
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 includes the effect of methodology on ET measurements, as well as the effect of the econometric procedure on the meta-regression estimates. Eight models were estimated, and two of these were selected: a fixed effects specification with dummy variables for the most significant studies without geographical effects (EFS), and a specification where the multiple observations are averaged and geographical effects included (OP). Based on model performance, the EFS option...

Technical Efficiency of the Crop Farms under the Various CAP Reforms: Empirical Studies for Germany, the Netherlands and Sweden AgEcon
Zhu, Xueqin; Oude Lansink, Alfons G.J.M..
We analyse the impacts of the CAP reforms on the technical efficiency of the crop farms. We use an output distance function and an inefficiency effects model which incorporates the influences of exogenous variables on farm efficiency. We formulate policy variables (e.g. the CAP subsidies) and producer characteristics as explanatory variables in the inefficiency effects model. We use the 1995- 2004 FADN data to estimate the production frontiers of the crop farms in Germany, Netherlands and Sweden, to derive their technical efficiency, and to determine the effects of the explanatory variables. The study shows that the 10-year average technical efficiency of crop farms is 59% in Germany, 75% in Netherlands, and 70% in Sweden. The average annual technical...
