Circulation and migration in third world settings: a comparison in Ecuador
Abstract:
This study is concerned with circulation, defined as temporary and repetitive migration that lacks any declared intention of a permanent or long-lasting change in residence. "The first section of the paper reviews pertinent circulation literature. Attention then turns to describing circulation and migration patterns in Ecuador, and identifying relationships between these patterns and regional differentials in economic development, both through cartographic and statistical analyses. A summary and conclusions comprise the last section."
