In this paper, we make a liquidity adjustment to the consumption-based capital asset pricing model (CCAPM) and show that the liquidity-adjusted CCAPM is a generalized model of Acharya and Pedersen (2005). Using different proxies for transaction costs such as the effective trading costs measure of Hasbrouck (2009) and the bid-ask spread estimates of Corwin and Schultz (2012), we find that the liquidity-adjusted CCAPM explains a larger fraction of the cross-sectional return variations.

A seasoned equity offering (SEO) can improve a firm’s stock liquidity and lower its cost of capital. This paper examines whether SEO firms achieve a liquidity gain and the sources of this gain. It explores the role of liquidity risk in explaining SEO long-run performance. The evidence shows that SEO firms experience significant post-issue improvements in liquidity and reductions in liquidity risk. Size and book-to-market matching fails to control for these liquidity effects, generating the low long-term post-SEO performance documented in the literature. After adjusting for liquidity risk, SEO firms show normal long-term performance.
