Abstract

This paper examines the opportunistic behavior of corporate insiders and analyzes the relationship between equity change and the possibility of delisting. The findings are summarized as follows. First, the larger the stake reduction of insider, the greater the negative excess return after announcement. In the delisting firm group, there is a significant decrease in equity and statistically significant results in the difference test between the comparative groups. The logistic regression analysis showed that the regression coefficient of equity change was negatively statistically significant, indicating a significant correlation between insider share change and the possibility of delisting. These findings are expected not only to provide useful information for investors, but also to be evidence of capital market information asymmetry.

본 연구는 부정사건이 발생한 기업을 대상으로 기업내부 관계자의 기회주의적 행태에 대하여 살펴보고 정보우위에 의한 지분변화가 자본시장에서의 시장퇴출 가능성과 지니는 관련성에 대한 실증분석을 실시하였다. 연구결과는 다음과 같이 요약된다. 먼저 사건 전후에 나타난 기업내부자의 지분감소가 큰 기업의 경우 공시이후에 보다 큰 음(-)의 초과 수익률이 나타나고 있다. 사건 기업 중 향후 시장퇴출로 이어진 기업집단에서는 뚜렷한 지분감소현상이 나타나고 있으며 비교집단 간 차이검정에서 통계적으로 유의한 결과를 보여주고 있다. 로짓회귀분석 결과 지분변화의 회귀계수가 음(-)의 통계적으로 유의한 결과 값을 나타내어 내부관계자의 지분감소가 클수록 향후 시장퇴출가능성이 증가하고 있음을 확인하였다. 이러한 연구결과는 정보우위에 따른 정보거래 가능성을 보여주는 결과로써, 자본시장 내외부자간 정보비대칭 현상에 대한 학술적 근거가 될 뿐만 아니라 이해관계자들의 의사결정에 유용한 정보를 제공해줄 수 있을 것으로 기대된다.
