This book discusses the role of space, time and cyclical behavior in world politics. More specifically, the political-economic role of lead economies – the world’s most innovative economies for finite periods of time – in world politics. These represent unusual concentrations of new technologies, energy sources, and military capabilities of global reach that play disproportional roles in the conduct of international affairs and the provision of limited governance at the most macro level. They also possess close links to economic growth and intense conflict. The book describes the economic, military and political processes behind the systemic leadership of a state at the international level. It also highlights the economic preconditions of systemic leadership, such as economic monopoly of new technologies and energy, which underlie the system leader’s material advantage over others. Analyzing lead economies and the evolution of power over a number of centuries, the author demonstrates how disruptions wrought by the emergence of new technologies and energy sources are partly responsible for global conflicts. This book appeals to international relations scholars as well as anyone interested in the political economy of systemic leadership, growth, and conflict in world politics.

The idea that political and economic power moves in coordinated cycles has long intrigued political scientists and political economists, for if a pattern exists in the rise and fall of international political power, a model explaining this pattern gains predictive qualities. In Leading Sectors and World Powers, George Modelski and William R. Thompson venture beyond previous attempts to explain why major powers rise, fall, and fight about their changing status to establish an explicit connection between war, economic innovation, and world leadership. They argue that surges in economic innovation, which in turn are tied to global war, determine leadership in the global system. Modelski and Thompson base their theory on the coordination of long cycles (phases of world order and decay punctuated by intensive bouts of global war) and K-waves (cycles delineating the wax and wane of leading industrial sectors). They contend that K-waves appear in paired sets correlated to long-cycle shifts in political power. Modelski and Thompson conclude by discussing the nature and timing of the next K-wave/long cycle peak, commenting on the relevance of it for U.S. industrial policy and speculating on the possibility of evolving away from this pattern in the near future.

This critical analysis of long-term trends and recent developments in world systems examines such questions as: Will the cycles of boom and bust, peace and war of the past 500 years continue? Or have either long-term trends or recent changes so profoundly altered the structure of world systems that these cycles will end or take on a less destructive form? The noted international contributors to this volume examine the question of future dominance of the core global systems and include comprehensive discussions of the economic, political and military role of the Pacific Rim, Japan and the former Soviet Union.
