During the 1997 Korean financial crisis, firms with higher ownership concentration by unaffiliatedforeign investors experienced a smaller reduction in their share value. Firms that hadhigher disclosure quality andalternative sources of external financing also sufferedless. In contrast, chaebol firms with concentratedownership by controlling family shareholders experienceda larger drop in the value of their equity. Firms in which the controlling shareholders’ voting rights exceeded cash flow rights and those who borrowed more from the main banks also hadlower returns. Our results suggest that change in firm value during a crisis is a function of firm-level differences in corporate governance measures.
