  Problem statement: Because of growing demand for water resources, increasing cost of supplying water and overdraft of underground waters, economists suggest water pricing policy to improve water allocation efficiency in Iran. While due to political risk, economic and cultural concerns, government tends to reject that advice. This study addressed questions of what policy alternatives to water pricing could be used to improve irrigation water allocation efficiency. Approach: Three policy options include water pricing, water complementary input factor taxes and output taxes were examined. In order to minimize the problems of bias produced by fully aggregated models, sample farms were classified into homogeneous groups of farmers by means of clustering technique. The analysis carried out by means of Positive Mathematical Programming (PMP), utilizing quadratic cost functions. Results: Results showed that effects of alternative policies were strongly dependent on group of farmers and that would create widespread effects on policy goals across clusters. The results also indicated that water pricing policy worked well in reducing the irrigation water use when the water price level was high and will have, in most cases, higher effects than other policy scenarios. Conclusion: Low level of input taxation wasn't a good driver in decreasing irrigation water demand and keeping the welfare level. Water pricing and output tax policies were better suited and effective than water complementary input factor taxation but both input factor tax and output tax policy at certain rates could be alternatives to water pricing policy. Water pricing policy had noticeable effects on social and environmental goals, while input and output taxes had small effects on that goals.

Problem statement:World economy has become increasingly integrated. There is an underlying assumption that integration into the world economy provides more opportunities for trade. The evidence shows that integration at the regional levels can help developing countries to prepare for the international economic integration. It will be important to outline and analyze past efforts at regional integration (regionalism) to have prospects for future arrangements.
Approach: Therefore this study assessed the impact of Iran membership in Economic Cooperation Organization (ECO) on agricultural exports by means of generalized gravity model. The econometric method was used to isolate and eliminate the regional agreement effects is panel and pooled data techniques.
Results:Our estimation results indicated positive and significant intra-trade impact of regionalism on Iranian agricultural export. Conclusion/recommendation: We had seen that, directly and indirectly, ECO could have positive effect on Iran agricultural trade. Indirectly, because similarity degree between Iran and the other ECO members in religion, border, ethnic, language and is very high in relation to the other chosen trade partners of Iran. Also a considerable share of the variability in ECO agricultural trade flows referred to uneconomic factors. Therefore, it seems that Iran would be able to expand its agricultural exports by gradually reducing trade barriers in ECO region and using of these ECO members' similarities.
