Schumpeter 體系와 Post Keynesian 體系의 比較 硏究 = A Comparative Study on the Schumpeterian System and Post Keynesian Dynamics

다국어 초록 (Multilingual Abstract)

The main purpose of this paper is to find feasibility of synthesis and its direction between Schumpeterian system and post Keynesian Dynamics. To carry out this purpose, in this paper, the theoretical structures of the two systems are analyzed.
1. Schumpeter's specific theory of the business cycle and its model.
Schumpeter's equilibrium concept is based on the Walras's "full equilibrium" in his specific theories of business cycle, however Schumpeter emphasized the uncertainty of expectation, introducing the time lag which succeeded the distribution theory.
Schumpeter regarded the self-induced innovation as a engine of economic development, and to the theory of business cycle combining the innovation and credit creation.
Concerning about Schumpeter's theory of business cycle, we can note that a trend regard a result of circular flow, the business cycle is considered as a decreasing process mechanism, and permanent creative desturction process is derived from correlation between innovation and competition.
2. The Harrod-Domar Dynamic Model and its Comparison with Schumpeter's Theory. Schumpeter regarded a cyclical width which formed by Kondratief cycles as a trend and the economic growth, in contrast with modern economics that understood a trend of growth as a Kondratief cycle itself.
With regard to the technical progress, Harrod and Domar considered the technical progress as an exogenous variable to the economic growth, though the former's passive attitude and the latter's positive attitude. Schumpeter however considered the technical progress as a self-induced element to the growth.
3. Hick's Theory of Business Cycle and its Comaprison with Schumpter's.
Concerning about the theory which explain estrangement from equilibrium and its process, we can not find differences in basic concepts between Hick's theory and Schumpeter's.
According to the Hick's Model, we can say that the fluctuation trend, in the course of expansion meet the lower turning point owing to full employment ceiling, and in the course expansion meet the lower turning point owing to full employment ceiling, and in the course of contraction the trend meet the upper turning point due to spontaneous investment which cause a multiplier and acceleration effect at lower equilibrium point, On the contrary. Schumpeter says that the expansion course of business cycle buing on a depression element in itself, therefore there is no spontaneous investment caused by innovation in the process of business recovering from its depression.
4. Synthesis of the two Dynamic Theories.
Having an insight into the whole, Post Keynesian take a divergent form of theory to Hicks's model, however, Schumpeter take a astringent one. Therefore the Dynamic Theory will be more complete and profitable if we put a thought of Schumpeter into the static mechanical theory of Hicks, and vice versa.
