Estimating Farm Efficiency in the Presence of Double Heteroscedasticity Using Panel Data
Hadri, Kaddour; Guermat, Cherif; Whittaker, Julie - In: Journal of Applied Economics VI (2003) November, pp. 255-268
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 …

Efficiency, Environmental Contaminants and Farm Size: Testing for Links Using Stochastic Production Frontiers.
Hadri, Kaddour; Whittaker, Julie - In: Journal of Applied Economics II (1999) November, pp. 337-356
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...

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...

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...

Productive efficiency analysis of quantitative economics journals through stochastic frontier analysis using panel data
Gavilan Ruiz, José Manuel; Ortega Irizo, Francisco Javier - In: Revista de métodos cuantitativos para la economía y … 30 (2020), pp. 297-311
The main goal of a scientific journal is to diffuse new knowledge. The number of citations received by a journal can be considered as a measure of this objective and, in turn, as a measure of productivity in relation to the production process in which the journals are involved. In order to...

Analysis of the Ef f iciency Determinants of Turkey’s Agriculture Sector by Two-Stage Data Envelopment Analysis (DEA)
AKTAN, Hande ERDOGAN; SAMUT, Pinar KAYA - In: Ege Academic Review 13 (2013) 1, pp. 21-28
In the country-wide providing the efficiency will only be provided by distributing the resources in the non-efficient provinces and regions well-balanced by correcting the deficiencies and by building separate plans. For this purpose, the efficiency of Turkey’s agriculture sector in 2009 on...

Effects of Input Composition on Technical Efficiencies of Textile Industries in Pakistan
Mahmood, Tariq - In: The Pakistan Development Review 51 (2012) 2, pp. 117-130
This paper studies the technical efficiencies of the textile manufacturing industries in Pakistan using 5-digit level industry data. Technical efficiencies are computed by the Data Envelopment Analysis technique assuming constant as well as variable returns to scale. The efficiency scores thus...
