Abstract

Inflation uncertainty is known to have deleterious effects on facilities investment by disturbing the corporate decision on the opportunity cost of investment. In this paper, we test the validity of this hypothesis in Korea by estimating the inflation uncertainty with both a time-varing parameter model with GARCH disturbances and the relative price volatility and then, estimate the facilities investment equation which includes those uncertainty indicators. The uncertainty indexes estimated by the above-mentioned methods continue to fluctuate even after the inflation rate has dropped dramatically reflecting the structural changes of Korea's economy since the financial crisis in 1997. As a result of estimation of the investment equation by both OLS and GMM, we find the inflation uncertainty has a negative effect on facilities investment with a statistical significance. Moreover, by means of Markov-switching regression model utilized to verify the non-linearity of this relationship, we draw a conclusion that this negative effect of inflation uncertainty heightens asymmetrically during the downturn periods of business cycle.

인플레이션의 불확실성은 기업투자의 기회비용 산정 등에 어려움을 줌으로써 설비투자를 위축시킬 수 있다. 본 연구에서는 우리나라에서도 이러한 가설의 성립여부를 검정하고자 시변모수(Time-Varying) GARCH모형과 품목별 상대가격 변동성을 통해 인플레이션과 관련된 불확실성을 측정하고 동 불확실성이 기업의 설비투자에 미치는 영향을 살펴보았다. 인플레이션 불확실성을 인플레이션율의 불확실성과 품목별 상대가격 변동성으로 각각 산출하여 추이를 살펴보면 우리나라의 인플레이션율이 구조적으로 낮아진 2000년대 이후에도 인플레이션 관련 변동성이 등락을 거듭하는 모습으로 보이고 있다. 또한, 동 지표들을 활용하여 설비투자와의 관계를 점검한 결과 인플레이션 불확실성은 예상한 바와 같이 기업의 설비투자에 유의한 부(-)의 영향을 미치는 것으로 나타났다. 특히 이러한 인플레이션 불확실성의 비대칭적 효과를 살펴보기 위해 마코프 국면전환 회귀모형(Markov-Switching Regression Model)을 추정한 결과, 인플레이션 불확실성의 투자위축 효과가 경기위축기에 더욱 커지는 것으로 나타났다.
