Perception of returns and negative externalities of growth in internal migration

This article presents the concepts of perception of returns and negative externalities of growth as two focal points of analysis to explain internal migration that occurs outside the rural-urban model. The discussion that arises suggests that it is necessary to analyze population growth resulting from population movements in semi-urban, metropolitan, as well as integrated or semi-integrated rural areas, going beyond the interpretation of motivations that are explained by potential options in the labor market and income. This study returns to the cost-benefit approach, and costs are explained by a causality associated with the negative externalities of growth; when migrants perceive them as obstacles to achieving their goals of well-being and quality of life, they seek alternatives that generate higher returns for these purposes.
