3) Liquidation Juglar's Influence - his work was challenged 100 years of economic beliefs
-Schumpeter brought great attention to Juglar's works
“Then came the great impulse due to the genius of Clement Juglar. He, first, by showing that crises are only elements of a much wider and deeper cyclical movement, unearthed the real problem; he, second, succeeded in describing empirically this cyclical movement; and, third, he contributed substantially towards its explanation."
