Farmers' Decision to Adoption of Modern Irrigation Systems Under Risk Condition: Application of Stochastic Efficiency With Respect to a Function Approach
نویسندگان
چکیده
To effectively tackle the issue of increasing irrigation water scarcity, farmers need to convert modern systems with lower use while achieving higher yields and profitability. Unlike government support cover a proportion modernizing costs by public subsidies in Iran, adoption rate is low. This due farmers' uncertainty about trade-off between benefits from yield improvement added production costs. The historical gross margin barley, wheat, forage corn, tomato under surface, drip, permanent sprinkler, semi-permanent sprinkler was generated using simulation survey-based data for published prices over 5-year period (2009–2015). stochastic dominance (SD) efficiency respect function (SERF) approaches were used evaluate risk various main crops Bakhtegan Basin. Estimating certainty equivalent (CE), we ranked alternatives at different absolute risk-aversion coefficient (r ) levels. findings show that drip corn have CE values all levels coefficient; however, preferred system barley wheat varies r . Moreover, estimated premiums revealed risk-neutral would pay move surface more efficient systems, whereas risk-averse be paid tendency change their system. important policy implication these results can consider justifying subsidy allocation manner induces risk-efficient systems.

abstract type-ii fuzzy logic has shown its superiority over traditional fuzzy logic when dealing with uncertainty. type-ii fuzzy logic controllers are however newer and more promising approaches that have been recently applied to various fields due to their significant contribution especially when the noise (as an important instance of uncertainty) emerges. during the design of type- i fuz...

رابطه ی میانِ هنر و شرایطِ اجتماعیِ زایش آن همواره در طولِ تاریخ دغدغه ی ذهنی و دل مشغولیِ اساسیِ منتقدان و نیز هنرمندان بوده است. از آنجا که هنر در قفس آهنیِ زندگیِ اجتماعی محبوس است، گسترش وابستگیِ آن با نهاد ها و اصولِ اجتماعی پیرامون، صرفِ نظر از هم سو بودن و یا غیرِ هم سو بودنِ آن نهاد ها، امری اجتناب ناپذیر به نظر می رسد. با این وجود پدیدار گشتنِ چنین مباحثِ حائز اهمییتی در میان منتقدین، با ظهورِ مکتب ما...
