Political disintegration is a persistent feature of world history. The Collapse of Complex Societies, though written by an archaeologist, will therefore strike a chord throughout the social sciences. Any explanation of societal collapse carries lessons not just for the study of ancient societies, but for the members of all such societies in both the present and future. Dr. Tainter describes nearly two dozen cases of collapse and reviews more than 2000 years of explanations. He then develops a new and far-reaching (...) theory that accounts for collapse among diverse kinds of societies, evaluating his model and clarifying the processes of disintegration by detailed studies of the Roman, Mayan and Chacoan collapses.

A world product time series covering two million years is well fit by either a sum of four exponentials, or a constant elasticity of substitution (CES) combination of three exponential growth modes: “hunting,” “farming,” and “industry.” The CES parameters suggest that farming substituted for hunting, while industry complemented farming, making the industrial revolution a smoother transition. Each mode grew world product by a factor of a few hundred, and grew a hundred times faster than its predecessor. This weakly suggests that (...) within the next century a new mode might appear with a doubling time measured in days, not years. (shrink)
