Dynamic Models of Segregation

Author: Thomas C. Schelling
Year: 1971
Summary: A classic paper in the study of emergent behavior. Schelling created a simple agent-based model showing how stark residential segregation could arise from the collective effect of individual choices, even when individuals have only a mild preference for living near people of the same 'color'. It's a powerful demonstration of how macro-level patterns can be unintended consequences of micro-level behavior.
