Kuznets swing

The Kuznets swing is a claimed medium-range economic wave with a period of 15–25 years identified 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.
