신용부도스왑 스프레드에 대한 체계적 위험의 영향
김정무, 박윤정
We study the cross-sectional relationship between systematic risk proportion and CDS spreads using CDS data on 18 Korean firms. The sample period covers from 2001 to 2012. Controlling for the total risk, we find that firms with higher systematic risk proportion have lower CDS spreads and this result is statistically and economically significant. Specifically, we find evidence that one percent increase in systematic risk proportion induces approximately one basis point decrease in CDS spread for a firm with a CDS spread of 100 bps. We also confirm the negative relation between systematic risk proportion and CDS spreads via various robustness tests. Thus, we conclude that the systematic risk proportion is an important determinant that Merton’s model does not capture.
