The main objective of this study is to examine the impacts of two demand side policies، namely; expanding food industries and externally increase in households’ demand for agricultural goods، on the growth of products in agricultural subsector. To this end، a social accounting matrix (SAM) is constructed based on the latest Iranian input- output table released in 2001. Then، production multipliers and income effects were calculated for four main agricultural subsectors. Finally، multiplier coefficients were decomposed، using the structural path analysis approach to distinguish short run and long run effects of the two policies. Results indicate that among agricultural related industries، food processing industry has a high potential for accelerating growth of raw agricultural products، both in short run and long run. Expansion of other related industries such as tobacco processing، carpets and rugs، hotel and restaurant services and agricultural activities are in the second place. Results of estimating income effects show that the impacts of income injection to the household groups، specially to lower income groups on growth of raw agricultural products is significant. Furthermore، redistribution of income from high to low income groups has almost the same effect. Accordingly، the latter two policies can be viewed as an alternative policy for agricultural growth both in short run and long run.

Job creation and reducing income inequality are two major objectives of the economic development plans in Iran. In this study, it is tried to evaluate the role of the agricultural sector in getting access to these objectives. To this end, an SAM was initially developed, based on the latest input-output table published by Iran's Statistical Centre in 2001, then the related labor and income multipliers for agricultural sector, and as well for other sectors were assessed. Finally, path decomposition analysis was utilized to determine the path with the largest affecting factors on employment and income generation. Results revealed that agricultural sector bears a high potential in creating jobs and generating income especially for low income groups. Sub-sectors including horticulture, animal husbandry, and crop production sectors carry the largest potentials in creating jobs and shrinking the gaps among rural and urban households and between low and high income groups in both rural and urban areas
