Are CFOs’ Trades More Informative Than CEOs’ Trades?

Journal of Financial and Quantitative Analysis 2012 47(4), 743-762 open access
We investigate whether trades made by chief financial officers (CFOs) reveal more information about future stock returns than those by chief executive officers (CEOs). We find that CFOs earn statistically and economically higher abnormal returns following their purchases of company shares than CEOs. During 1992–2002, CFOs earned an average 12-month excess return that is 5% higher than that by CEOs. The superior performance by CFOs occurs notwithstanding controls for risk factors and persists even after their trades are publicly disclosed. Further analysis shows that CFO purchases are associated with more positive future earnings surprises than CEO purchases, suggesting that CFOs incorporate better information about future earnings.

The Effect of Organization Capital on the Cost of Bank Loans

Journal of Financial and Quantitative Analysis 2023 58(6), 2579-2616 open access
We find that organization capital is negatively related to the cost of bank loans. This finding is robust to additional analyses including those that address omitted variable bias and reverse causality. In addition, we find that organization capital reduces all-in-spread-undrawn. When we decompose the bank loan cost, we find that organization capital increases facility fees due to its risk-engendering characteristics. Finally, we find that organization capital is positively associated with a high likelihood of the presence of inventors and innovation output, consistent with the argument that organization capital is embedded in the key talent within a firm.

Do activist hedge funds target female CEOs? The role of CEO gender in hedge fund activism

Journal of Financial Economics 2021 141(1), 372-393 open access
Using a comprehensive US hedge fund activism dataset from 2003 to 2018, we find that activist hedge funds are about 52% more likely to target firms with female CEOs compared to firms with male CEOs. We find that firm fundamentals, the existence of a “glass cliff,” gender discrimination bias, and hedge fund activists’ inherent characteristics do not explain the observed gender effect. We also find that the transformational leadership style of female CEOs is a plausible explanation for this gender effect: instead of being self-defensive, female CEOs are more likely to communicate and cooperate with hedge fund activists to achieve intervention goals. Finally, we find that female-led targets experience greater increases in market and operational performance subsequent to hedge fund targeting.

Labor law and innovation revisited

Journal of Banking & Finance 2018 94, 1-15 open access
This paper examines the impact of changes in job security on corporate innovation in 20 non-U.S. OECD countries. Using a difference-in-differences approach, we provide firm-level evidence that the enhancement of labor protection has a negative impact on innovation. We then discuss possible channels and find that employee-friendly labor reforms induce inventor shirking and a distortion in labor flow. Further investigation reveals that the negative relation is more pronounced in (1) firms that heavily rely on external financing, (2) firms that have high R&D intensity, (3) manufacturing industries, and (4) civil-law countries. Our micro-level evidence indicates that enhanced employment protection impedes corporate innovation.
