“The Russian economist Nikolai Kondratieff was executed on Stalin’s orders in the mid-1930s because his econometric model predicted, accurately as it turned out, that collectivization of Russian agriculture would lead to a sharp decline in farm production. The “fifty-year Kondratieff cycle” was based on the inherent dynamics of technology. Every fifty years, so Kondratieff asserted, a long technological wave crests, popularized in the West by Austro-American economist Joseph Schumpeter in his book Business Cycles (1939).”

From the book innovation and entrepreneurship by Peter Drucker (1985)
