![]() | Secular Cycles Subjects: Population -- Mathematical models; Demography -- Mathematical models; Business cycles -- Mathematical models; Economic development -- Mathematical models; Many historical processes exhibit recurrent patterns of change. Century-long periods of population expansion come before long periods of stagnation and decline; the dynamics of prices mirror population oscillations; and states go through strong expansionist phases followed by periods of state failure, endemic sociopolitical instability, and territorial loss. Peter Turchin and Sergey Nefedov explore the dynamics and causal connections between such demographic, economic, and political variables in agrarian societies and offer detailed explanations for these long-term oscillations--what the authors call secular cycles. Peter Turchin is professor of ecology and evolutionary biology and adjunct professor of mathematics at the University of Connecticut. Sergey A. Nefedov is senior research scientist at the Institute of History and Archaeology of the Russian Academy of Sciences, Ural Branch. |
