The joint impacts of increasing the world price of rice, resulting from the export policies in Thailand along with changes in tariff rates in Iran, on social welfare are analyzed in the two countries. Because Iran is a small country in terms of the volume of world rice trade its policies do not influence Thai social welfare. Results of this study show that in order to maximize its own social welfare, the government should impose a modest tariff rate of approximately 3%. This is much less than the actual tariff rate applied in recent years, e.g. 19% in 2007. https://ijes.shirazu.ac.ir/article_1563_02b927c62a27a064807786482acc8f3e.pdf
