Originally published over twenty-five years ago, "Micromotives and Macrobehavior" still feels fresh today. And the subject of these stories - how small and seemingly meaningless decisions and actions by individuals often lead to significant unintended consequences for a large group - is more important than ever. In one famous example, Thomas C. Schelling shows that a slight-but-not-malicious preference to have neighbours of the same race eventually leads to completely segregated populations. The updated edition contains a new preface and the author's Nobel Prize acceptance speech.
