Rendimentos crescentes e a distribui？？o internacional de renda

the existence of increasing returns in high technology industries assigns a path dependent character to the international division of labor. rich countries, first entrants in these industries, enjoy permanent advantages that prevent, in a free market environment, the development of such industries in middle-income countries. this dynamics allows the former group of countries to experience a higher growth rate of labor productivity than the latter, and, as a result, increases the gap between the workers' standard of living in these countries. it is up to the states of middle-income countries the task of devising development strategies capable of breaking such pattern and improving the international distribution of income.
