Diversification and Specialization Paradox in Developing Country Trade

This paper examines and resolves a puzzling issue associated with less developed country (LDC) export compositions. Since the newly industrialized country (NIC) takeoff during the early 1970s, LDC exports have involved an increasingly broader and diversified export base. Yet trade theories, both "old" that focus on classic comparative advantage, and "new" which rely on scale economies, lead to expectations of growing specialization as a concomitant of LDC takeoff. This study examines periods of rapid growth and structural transformation of trade for a representative group of LDCs covering a wide geographic and temporal sample
