Despite many apparently positive signs, however, there is no evidence of improved income shares for developing country exporters. In fact, some new research (discussed in the latest Trade and Development Report 2002 (TDR) produced by UNCTAD) suggests that product diversification in itself ensures neither more dynamic exports nor even higher incomes from such activities. The report argues that while the share of developing countries in world manufacturing exports, including those of rapidly growing high-tech products, has been expanding rapidly, the income earned from such activities does not appear to share in this dynamism.
