Genuine long cycles of the industrial and post-industrial ages (19th-21st centuries)

The author questions the existence of N. Kondratiev’s supercycles and waves by showing that the essence of the long cycles cannot be understood without their strong connection with 7-11 year Juglar cycles. It is the interchange of these cycles that defines the evolution of global economy, while the long 21-30-year cycles in fact consist of three Juglar cycles.
