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...

abstarct precise knowledge of all components of water balance is essential to optimize water use in irrigated agriculture. however, water balance components are difficult to measure in required time intervals because their measuring is time consuming and costly. unsaturated zone simulator models are useful tools for predicting the effects of agricultural management on crop water use and can be ...

Low efficiency has been the bottleneck that is hindering agricultural products logistics to play the role in improving economic and social development. But relevant research achievements are not many. This paper studies agricultural products logistics efficiency from 2008 to 2011 in China based on DEA and Malmquist index and finds that during later period of study, the total factor productivity...

This paper analyzes the relationships between bilateral trade and economic growth in the U.S. and Korean economies. Using quarterly data from 1990 to 2008, the theoretical procedures utilize Ordinary Least Square (OLS) and Seemingly Unrelated Regression (SUR) models under the static model assumption, an Impulse Response Function (IRF) and Forecast Error Variation Decomposition (FEVD) under the ...

BACKGROUND Self-reported work-related ill-health (WRI) statistics suggest that agricultural workers in the UK are at an increased risk of musculoskeletal disorders (MSD), skin and respiratory disease. However, there is little comprehensive medically reported information on WRI in the UK agricultural sector. METHODS Cases of WRI within the UK from 2002 to 2008, as reported to The Health and Oc...
