|Proposed Economic Waves|
|Juglar fixed investment||7–11|
|Kuznets infrastructural investment||15–25|
Kuznets swing is a claimed medium-range economic wave with a period of 15–25 years found in 1930 by Simon Kuznets. Kuznets connected these waves with demographic processes, in particular with immigrant inflows/outflows and the changes in construction intensity that they caused, that is why he denoted them as “demographic” or “building” cycles/swings. Kuznets swings have been also interpreted as infrastructural investment cycles.
Economists now recognize the Kuznets swing as the 18 year land cycle. This cycle of boom and bust could be smoothed or avoided altogether by levying an annual tax on the value of land (Land Value Tax)" 
Kuznet's finding was debunked by Howrey (1968). Howrey claimed that the apparent business cycle found by Kuznets was an artifact of the filter Kuznets used. Howrey suggested that the same cyclical pattern could be found in white noise series when the Kuznets filter was applied. However, Kuznets claims swings can be found in the world GDP dynamics even without the application of the Kuznets filter.
