두 제약조건하의 경제적 파급효과에 관한 비교 연구 : 총산출 제약(OO모형)과 최종수요 제약(FF모형)을 중심으로

Fundamentally, the economic impacts derived from the models of IO(input-output), OO (output-output), and FF(final demand-final output) between final demand(f), total output(χ), and final output(ο) are based on the unrestricted(or unconstrained) conditions on the economic impact assessment. In the real economic circumstances, however, let us now consider a new scenario where any new constraints into the real economy are constrained on the supply and demand sides. On the basis of the latest research findings and results from the economic impact under constraints for total output and final demand in the most recent economic literature, the specific objectives of this paper can be summarized as follows. (1) We testify the usefulness and necessity for the economic impact under constraints on the supply(total output) and demand sides(final demand) through the models of OO and FF developed recently by the author as alternatives of the IO model. (2) We derive the models for the varied economic impacts under two different constraints for total output(ο) and final demand(f) and interpret the economic characteristics and meanings of the models driven. (3) Based on constraints for total output(ο) and final demand(f), we empirically calculate the varied economic impacts by 28 endogenous sectors through the OO and FF models from the raw data of the 2010 Input-Output Tables of Korea.
