Prior work on the connection between firm-level corporate governance and firm value, both in the U.S. and worldwide, relies on cross-sectional data. This leaves open the possibility that endogeneity or omitted firm-level variables explain the observed correlations. Korea provides a unique laboratory for addressing these empirical issues. Using panel data on the governance of Korean public companies over 1998-2003, we report time-series evidence that an overall corporate governance index is an important and likely causal factor in explaining these firms' market values. In prior cross-sectional work, Black, Jang, and Kim (2006) finds strong OLS and instrumental variable evidence that a Korean corporate governance index (KCGI) predicts higher firm market values, measured by ln(Tobin’s q) using 2001 data. Using their index extended over a seven-year period, we show here that the coefficient on KCGI remains significant and economically important over time and with firm random and fixed effects, which capture only the time-series variation of governance. When we decompose KCGI into subindices, subindices that reflect substantive governance are important; while procedure is not. Better-governed firms pay higher dividends than other firms, but do not report higher accounting profits.
