Wicksell, Keynes Economic Theory, Tradition,

As an economist of Nordic School, Knut·Wicksell is controversial and legendary. Wicksell is referred to as "Marshll of Scandinavia" in the Western economic history for his being the first person to oppose the "Say's Law" and the first economist to deny the traditional economic theory under which Capitalist Economy has the ability to achieve automatic equilibriums. Thus, Wicksell is a very important person in the history of economic thought.Over the century, the appraisal of Wicksell of his historical achievements has never been as the same importance as the great economist—John·Maynard·Keynes. It's indisputable that Keynes is the greatest Economist of his periods. Keynes's three main economic literatures— 1923, and < The General Theory of Employment, Interest, and Money > 1936, have a profound impact on his successors of western economist and revolutionary changes in western economic theory. But Wicksell's contributions to modern macroeconomics remain the earliest and fundamental. For example, the Nordic School first introduce the Totality Problem into the core system of economic theory and Wicksell is the founder of the Nordic School and more than a century ago Wicksell has already grasp the core concerns of modern macroeconomics—the relation between the nominal variables and real variables. Not only dose Wicksell develop the Bohm·Bawerk's Theory of Interest on Capital and Walras's General Equilibrium Theory, but he also originate the Cumulative Process Theory. So actually Wicksell is the founder of modern macroeconomics.This article adopts the method of comparative method. First it introduces the core economic theory of Wicksell's, then it introduces the key economic thought of Keynes's. After that, the article deeply digs Wicksell's economic thought reflected inside Keynes's economic thought. At last, it draw the conclusion that as the greatest economics and the founder of modern macroeconomics, Keynes's economic theory is constructed on the basic concept of Wicksell's economic thought and evolves with his own creativity.
