Abstract

According to the importance of imports in the process of development, on the one hand, and limitation of foreign exchange reserves specially during the post revolutionary period, on the other hand, the Irans relevant trade policies have been mostly implemented towards import compression, and particularly directed towards imported capital and intermediate goods, and also specific trade partners. However, due to the globaiization process and Irans attempts for joining WTO, it seems that there is a need for changes in import structure based upon the countrys development requirements. This may be somehow conducted through trade liberalization. Due to the identification of this process, this paper tends to estimate the long-run import budget share, arising from various supplying resources for Iran. The formulation is based upon typical model of the Almost Ideal Demand System (AIDS). After estimating import demand, we test the hypothesises that import demand is homothetic, homogenous and symmetric. Using the dynamic adjustment process of the first order of Error Correction Model (ECM), the paper estimates the long-run balanced import budget shares, domestic sales share as well as long-run expenditure and compensated price elasticites over the 1978-2002 period. Estimation results obtained indicate that implementing a type of trade liberalization policy can possibly lead the share of domestic sales to decline, while total import budget share will grow resulting in trade creation, and particularly trade flows may be deviated from other partners to Irans second ten major trading partners.
