The business cycle refers to the recurrent periods during which a nation's economy moves through phases of recession and recovery. Historical research by economists has identified both short-term and long-term cycles.
The Kondratieff Cycle, also known as the Kondratieff Wave, is a theory proposed by Soviet economist Nikolai Kondratieff in the 1920s, which suggests that the economies of the Western capitalist world experience major up-and-down 'supercycles' lasting 50 to 60 years.
The Long-Wave Cycle, also known as the Kondratieff Cycle, refers to a theorized cycle in the modern world economy spanning approximately fifty to sixty years, marked by periods of high sectoral growth followed by declines.
