Analysis (DEA) have become very popular in the analysis of productive efficiency. This paper undertakes a comparison of the SFA and the constant returns to scale (CRS) and variable returns to scale (VRS) output-oriented DEA models, based on a sample of 165 dairy farms in Greece. However, the aim...

A steep decline in coffee prices at the producer level led to considerable pressure for farmers in Costa Rica and producer countries all over the world. One possible reaction was moving to specialty markets, where price pressure was perceived to be lower. We use original survey data from 2002/03...

Este estudio estimó la forma funcional de producción cafetera en Colombia mediante fronteras estocásticas (FEP). Con esto, se analizó la importancia de los principales insumos empleados en la producción de café (cantidad de hectáreas cultivadas, mano de obra utilizada, maquinaria...

This article presents a new framework for the impact evaluation studies of programs that aim to increase efficiency and productivity of firms. Likelihood ratio statistics support a spatial autoregressive stochastic production model that estimates the technical efficiencies of matched subsamples...

This paper proposes an alternative specification for technical efficiency effects in a stochastic production frontier model. The proposed specification is distribution free and thus eschews one-sided error term present in almost all the existing inefficiency effects models. The efficiency...

Parametric Stochastic Frontier Analysis (SFA) and non-parametric Data Envelopment Analysis (DEA) have become very popular in the analysis of productive efficiency. This paper undertakes a comparison of the SFA and the constant returns to scale (CRS) and variable returns to scale (VRS)...

This article offers a methodology to address the endogeneity of inputs in the input distance function (IDF) formulation of the production processes. We propose to tackle endogenous input ratios appearing in the normalized IDF by considering a flexible (simultaneous) system of the IDF and the...

This paper proposes a stochastic frontier panel data model which includes time-invariant unobserved heterogeneity along with the efficiency effects. Following Paul and Shankar (2018), the efficiency effects are specified by a standard normal cumulative distribution function of exogenous...

This article provides a generalization of the materials balance-based production model introduced by Coelli et al. (2007). Based on this, some new environmental efficiency (EE) measures are presented. The Coelli et al. (2007) EE measure and its extension by Rødseth (2016) produce biased...

This article uses panel data estimation techniques to examine technical efficiency of individual dairy farms in northern Germany. To the extent that agricultural production is characterised by heterogeneous production conditions, estimation techniques that do not account for unobserved...
