A Review of Relationship between Export Diversification and Stability of Export Earnings in IRAN

This paper investigates non-oil export.diversification and its effects on export earnings stablization in Iran. For that purpose, we construct some measures for diversification and stability of each commodity group. The measures are: commulative export experience function, traditionality index and elasticity of export variance. We used the last measure for stability of each commodity group in total export and the others for diversification export, respectively. Then, we applied the indices for the full set of 40 two-digit U.S. Commodity groups in Iran (1358-77) . The results indicate that the majority of industrial commodities (about two-third)had positive effect on stability of export earnings, but the others did not affect the stability. Therefore, our finding show that adopting and implementing diversification policies are justifiable
