克里门特·朱格拉(Clèment Juglar,1819-1905)法国经济学家原为医生,后改为研究经济周期。他在1862年发表的《论德、英、美三国经济危机及其发展周期》一书中,根据他搜集的统计数据,计算出平均9至11年发生一次经济周期。这个周期被熊彼特命名为朱格拉周期,并指出是一种中周期。后来英国专家汉森用朱格拉的计算方法,使用英国1795年至1937年的统计数据,计算出了平均周期长度为8.35年,从而把朱格拉周期增为8至11年。
Clèment Juglar, 1819-1905
French doctor and statistician. One of the earliest proponents for the development of an "economic" theory of the business cycle (1862), thus can be called the father of business cycle theory. Juglar identified the 7-11 year industrial cycle, that has since been associated with his name. His findings on credit cycles spurred the subsequent efforts of overinvestment theorists such as Tugan-Baranovsky.
