This study examines net migration in less developed countries (LDCs) within the context of a world economic system and an urban ecological framework. Data are obtained from the "1987 World Development Report," the "1983 and 1987 World Bank Tables," and the 1984 UN Demographic Yearbook. It is posited that international migration is a direct response to the changes in the ecological subsystems in LDCs. The framework of this analysis relies on analyses by Sly and Tayman that found in multi-equation models that migration was a demographic response to environmental conditions created by organization and technology. The maximum likelihood estimates derived from the proposed structural model indicate that net capital flows positively influence net migration rate directly. Large transfers of capital were associated with net migration. It is suggested that a reduced percentage in the labor force in agriculture may have a greater impact on emigration than wages or social disadvantages. Gross national product had a smaller impact on migration than net capital outflows. Exports had a positive impact on net migration. There was a direct negative effect of value added to manufacturing on net migration, and the direct negative effect was greater than the positive indirect effect. The percentage of persons economically active had a positive impact on net migration. Increased economic activity was related to increased emigration. The evidence suggests that world economic systems did have an impact on emigration, when profits were not invested in domestic economies of LDCs. Findings suggest that the value added to manufacturing, the percentage engaged in agriculture, and the economically active population mediated the impact of trade on net migration.
