Cassava farming in Central Lampung Regency has lower productivity than its potential. Low is one of the essential indicators that are not efficient yet. This study investigates income level cassava farming, technical efficiency and factors causing inefficiency, also economic farming. research was conducted center, Terbanggi Besar District Terusan Nunyai District, Lampung. Data were collected fr...
Abstract Shrimp aquaculture systems vary from primitive (extensive/improved extensive) to more industrialized (intensive/semi‐intensive) farms, and the impacts of environmental shocks may differ between them. This article applies Cobb–Douglas stochastic production frontier function evaluate determinants that impact inefficiency these intensive extensive in Vietnam. Data is a survey 436 white‐le...
Application of DEA and SFA on the Measurement of Agricultural Technical Efficiency in MENA Countries
The purpose of this paper is to investigate the levels of technical efficiency in agricultural sector of MENA countries by using Data Envelopment Analysis (DEA) and Stochastic Frontier Analysis (SFA) approaches in 2007-2008. The results show that the total average of technical efficiency is as follows: DEABCC(0.770)>DEACCR(0.744)>SFA(0.479), and among all MENA countries, the best performanc...
Abstract Climate adaptation is an essential strategy for responding to climate change at local levels and required sustainable food production meet the growing demand. In this light, study analyzed effects of strategies on technical efficiency maize farmers in Northern Ghana. This involved a total 619 that were selected through multistage sampling procedure. A Cobb-Douglas stochastic frontier w...
A number of studies have explored the semiand nonparametric estimation of stochastic frontier models by using kernel regression or other nonparametric smoothing techniques. In contrast to popular deterministic nonparametric estimators, these approaches do not allow one to impose any shape constraints (or regularity conditions) on the frontier function. On the other hand, as many of the previous...
The car manufacturing industry, one of the largest energy consuming industries, has been making a considerable effort to improve its energy intensity by implementing energy efficiency programs, in many cases supported by government research or financial programs. While many car manufacturers claim that they have made substantial progress in energy efficiency improvement over the past years thro...
Received analyses based on stochastic frontier modeling with panel data have relied primarily on results from traditional linear fixed and random effects models. This paper examines several extensions of these models that employ nonlinear techniques. The fixed effects model is extended to the stochastic frontier model using results that specifically employ the nonlinear specification. Based on ...
