Quality Upgrading and the Stages of Diversification

This paper explores the contribution of product quality upgrading in the process of export diversification. To do this, the paper builds a multisector model following Eaton and Kortum (2002) in which product quality is incorporated as a key feature. The model is then calibrated to generate predictions about the degree of export diversification in a number of East Asian countries. It is shown that quality upgrading is a key factor to understand the changes in the degree of export diversification in the majority of countries in our sample.
