Efficiency, Environmental Contaminants and Farm Size : Testing for Links Using Stochastic Production Frontiers
Hadri, Kaddour; Whittaker, Julie M. - 2004
This paper investigates whether there is any relationship between farm size, technical efficiency and the use of agrochemicals which are potentially environmentally contaminating. These questions are pertinent in the context of current EU policy decisions. Using two models of stochastic frontier...

A comparison of panel data models in estimating technical efficiency
Rashidghalam, Masoomeh; Heshmati, Almas; Dashti, Ghader; … - 2016
The purpose of this paper is two-fold. First, it compares the performance of various panel data models in estimating technical efficiency in production. Second, it applies various stochastic frontier panel data models to estimate the technical efficiency of Iran's cotton production and to...

Firms' export performance: a fractional econometric approach
Faria, Samuel; Rebelo, João; Gouveia, Sofia - In: Journal of business economics and management 21 (2020) 2, pp. 521-542
Export activities have become crucial to firms' competitiveness, with determinants of export performance being a challenging field of research, since there is no consensus regarding the explained and explanatory variables or on the econometric methods to be used. Using a panel data of Portuguese...

Estimating Farm Efficiency in the Presence of Double Heteroscedasticity Using Panel Data
Guermat, Cherif; Hadri, Kaddour; Whittaker, Julie M. - 2015
inefficiencies are sensitive to specification errors. One source of such errors is heteroscedasticity. This paper addresses this … issue by extending the Hadri (1999) correction for heteroscedasticity to stochastic production frontiers and to panel data …. It is argued that heteroscedasticity within an estimation can have a significant effect on results, and that correcting …

A metafrontier analysis on the performance of grain-producing regions in Norway
Alem, Habtamu - In: Economies : open access journal 9 (2021) 1/10, pp. 1-10
Previous application of the stochastic frontier model and subsequent measurement of the performance of the crop sector can be criticized for the estimated production function relying on the assumption that the underlying technology is the same for different agricultural systems. This paper...

Bayesian treatments for panel data stochastic frontier models with time varying heterogeneity
Liu, Junrong; Sickles, Robin C.; Tsionas, Efthymios G. - In: Econometrics : open access journal 5 (2017) 3, pp. 1-21
This paper considers a linear panel data model with time varying heterogeneity. Bayesian inference techniques organized around Markov chain Monte Carlo (MCMC) are applied to implement new estimators that combine smoothness priors on unobserved heterogeneity and priors on the factor structure of...

Identifying Different Technologies Using a Latent Class Model : Extensive Versus Intensive Dairy Farms
Alvarez, Antonio - 2010
In this article, we use a stochastic frontier latent class model to estimate the technology of dairy farms according to their degree of intensification. The results are compared with a model which assumes that the technology is common to all farms. The empirical analysis uses data on a balanced...

Production risk, energy use efficiency and productivity of Korean industries
Khayyat, Nabaz T.; Heshmati, Almas - 2014
Korea imports all of its primary energy, which leads to high dependency and vulnerability related to its energy supply. Efficiency in the use of energy is a way to reduce dependency and emissions. This study provides empirical results of the stochastic production process in energy use. Special...

A Spatial Autoregressive Stochastic Frontier Model for Panel Data Incorporating a Model of Technical Inefficiency
Tsukamoto, Takahiro - 2019
By integrating Battese and Coelli's (1995) model and the spatial autoregressive model (SAR), a spatial autoregressive stochastic frontier model for panel data is developed. The main feature of this frontier model is a spatial lag term of explained variables and the joint structure of a...
