ヨーゼフ・シュンペーター
Joseph Kitchin (1861–1932) was a British businessman and statistician. Analysing American and English interest rates and other data, Kitchin found evidence for a short business cycle of about 40 months. His publications led to other business cycle theories by later economists such as Nikolai Kondratieff, Simon Kuznets, and Joseph Schumpeter.
