This article analyses the effects of foreign exchange commitment and exchange rate unification policies on Iran’s non-oil exports during the last three decades. In addition, the effects of these policies on non-oil exports have empirically been estimated. For this purpose, an export supply model was estimated using the econometrics technique of Auto Regressive Distributed Lag (ARDL) and reliable Iranian data for the last three decades. The empirical results of this paper shows that during the entire period of 1977-2008, foreign exchange commitment policy has caused non-oil exports to decline, but exchange rate unification policy has had positive effects on Iran’s non-oil exports.

One of the main goals of developing countries is to achieve a sustainable economic growth. The exports promotion can directly help economic growth. Therefore, recognizing the factors influencing economic growth is of utmost important. Regarding the significance of factors affecting non-oil exports in trade policy making, this study aims to investigate the impact of exports insurance subsidy and other relevant variables on non-oil exports in Iran. To do this, the short- and long-term relationships between non-oil exports and exports insurance subsidy are estimated by Auto-Regressive Distributed Lags (ARDL) over the period 1995-2011. The results show that exports insurance subsidy is of positive effect on non-oil exports in both short- and long-term.

This paper investigates the short- run and long-run effects of government size and exports on the economic growth of Iran as a developing oil export based economy for the period of 1974 - 2008 using an autoregressive distributed lags (ARDL) framework. A modified form of Feder (1982) and subsequently Ram’s (1986) model has been applied to include both government size and exports in growth equation. The findings show that in long run and short run the Armey curve (1995) is valid, indicating that both a very big size and a too small size of government are harmful for growth and government should adjust its size. The results also show that total exports, the amount of oil exports in terms of barrels and oil prices affect economic growth positively and significantly both in short-run and long-run. However, non-oil exports do not have a significant effect on growth in the long run
