| Abstract: | Evidence is presented regarding strengths and limitations of portfolio approaches as applied to diversifying export earnings. An empirical application using data from Malawi, Tanzania, and Zimbabwe is used to demonstrate these strengths and limitations. Modifications of the typical portfolio approach to export diversification are presented; these modifications help make the approach more plausible for use in developing countries. The modified approach is shown to provide guidance to policymakers who seek simultaneously to increase export earnings and reduce their instability. |
