Nowadays, besides of other factors affecting macroeconomic instability, the chronic trade account deficit has a crucial role in this instability. It is clear that the trade account deficit can be risen from instability of goods and services exports. Therefore, in this research, along with investigating the concept of non-oil export instability, we’re going to study the most important factors shaping this phenomenon during the period of 1971-2008. To do this, we have chosen the best index for measuring export instability and also other indices for measuring commodity and geographical concentration. Then, by using Bound test method, suggested by Pesaran(2001), we have investigated the long run relationship among the variables. In the next stage, the Variance decomposition method, suggested by Liu and Xin(2008), has been employed to analyze the isolated effects of commodity and country groups on export instability. Our results show that commodity and geographic concentration along with oil and industrial exports have a significant effect on non-oil export instability. In fact, when considering geographical concentration, the largest instability comes from OPEC market.
