In course, findings are applied Multiregional Global Analysis Project 10 then calibrated for projection. Findings results indicate that there a decrease cereals production because eventually it increases prices cereals, decreases local consumption and, result, causes loss welfare. Subsidies SAFTA have been found no substantial increasing security Asia. Originality/value concept demand all way focuses fiscal trade
