Abstract

This study examined whether there is a difference in cost asymmetry between a corporate listed on KOSDAQ and a corporate listed on KOSPI, and whether there is a difference in cost asymmetry depending on the size of the listed corporate. In the previous study, cost asymmetry was examined only for listed corporate, but the difference in size between KOSDAQ-listed corporate and KOSPI-listed corporate was not examined. However, according to many studies, since the characteristics of corporate and firm risks are different between corporate listed on KOSPI and corporate listed on KOSDAQ, or even for listed corporate, such an impact may affect the decision-making of internal resource allocation. The analysis was conducted that there would be a difference in the impact. For this study, the results of analyzing the KOSPI and KOSDAQ markets from 2011 to 2019 using the cost behavior model of Anderson et al. (2003), There was a difference in cost behavior in the KOSPI and KOSDAQ markets. Overall, as in previous studies, Cost Stickiness was appeared. but in the case of the KOSPI market, Cost Stickiness was mitigated.It was found that corporate with large corporate size made the decision to dispose of idle resources more clearly when sales decreased. In addition, it was observed that the higher the foreign investor's ownership ratio, the KOSPI market, and the larger the corporate size, the more clearly the Stickiness of cost was mitigated. This study expands research on cost asymmetry and reveals that there is a difference between the KOSPI market and the KOSDAQ market, and between the size of the corporate, and has a differentiation from previous studies.

본 연구는 국내 상장시장 간 원가의 비대칭성의 차이가 있는지, 상장기업의 기업 규모에 따라 원가의 비대칭성이 차이가 있는지 검증하였다. 기존의 연구에서는 상장기업만을 대상으로 한 원가의 비대칭성은 살펴보았지만, 상장기업 간의 규모의 차이는 살펴보지 않았다. 그러나 다수의 연구에 따르면 상장시장 간 또는 상장기업이라 할지라도 기업의 특성이나 기업고유의 위험(firm risk)이 서로 다르기 때문에 이와 같은 영향이 기업 내부 자원배분 의사결정에 미치는 영향에 차이가 있을 것이라고 보고 분석을 실시하였다. 이를 위해 2011년부터 2019년까지 유가증권시장과 코스닥시장을 대상으로 Anderson et al.(2003)의 원가행태 모형을 이용하여 분석한 결과, 유가증권시장과 코스닥시장의 원가행태는 차이가 있는 것으로 나타났다. 전반적으로 선행연구와 마찬가지로 원가의 하방경직성이 보고되었으나 유가증권시장의 경우 원가의 하방경직성이 완화됨을 확인할 수 있었다. 기업규모가 클수록 매출액이 감소할 때 유휴자원의 처분의사결정이 더 뚜렷한 것으로 나타났다. 추가적으로 외국인투자자 지분율이 높은 경우, 유가증권시장일수록, 기업규모가 클수록 원가의 하방경직성의 완화는 더 크게 나타남을 관찰할 수 있었다. 본 연구는 원가의 비대칭성에 관한 연구를 확장하고 상장시장 간, 기업규모 간의 차이가 존재함을 밝힌 연구로써 선행 연구와의 차별성을 갖는다.
