Argues that surges in economic innovation, which in turn are tied to global war, determine leadership in the global system. The authors base their theory on the coordination of long cycles (phases of world order and decay punctuated by bouts of global war) and K-waves (cycles delineating the wax and wane of leading industrial sectors). After testing their theory against historical evidence, they conclude by discussing the nature and timing of the next K-wave/long cycle peak and its relevance for U.S. industry.
