George does a nice overview on
the following:
The major cycles are (roughly is descending order of
credibility among academics):
Joseph Kitchin's (1920's) 3-5 year
cycle, sometimes blurred and glossed over as the "presidential cycle".
Reality? It's something of an inventory cycle.
Clement Juglar's (1862) 7-11
year cycle of fixed investment, occasionally blurred and glossed-over at "the
real estate cycle" or "the California real estate" cycle.
Simon Kuznet's (1930)
infrastructure investment cycle. 15-25 years.
Nicholas Kondratieff's
(1926) long-term business cycle, argued [by some] to be 45-60 years
duration. Also called the K-wave. The cause and proper
label of the K-wave is still hotly debated
Grand Economic
Supercycle: 250 years, plus or minus a revolution, typically made up
of 5 K-waves.
