Abstract

The possible WTO membership of Iran not only depends on liberalizing the trade sector but also needs to meet the relevant conditions of a specific development process. To examine these conditions we specify an unconstrained first-order autoregressive model of the Almost Ideal Demand System(AIDS), as a long-run demand model, for Iran’s import allocation over foreign and domestic supplies of manufacturer.
   In this paper, the structural stability of the AIDS model is tested by using time series data for the period 1993-2002. The significance of trade liberalization, proxied by a dummy variable over the period reveals both trade creation and trade diversion in the Iran’s imports
   In addition, the conduction of different scenarios on reducing tariff, arising from the Iran’s fourth development program, over the ex-ante period 2003-2007 indicates that there is no structure break in the country’s import demand. The implication of this result is that a decrease in tariff through a relatively accelerated speed of adjustment can be utilized for the promotion of trade between Iran and her trading partners.
