Corporate Governance, Product Market Competition and Equity Prices

Abstract

This paper examines whether firms in non-competitive industries benefit relatively more from good governance than do firms in competitive industries. Consistent with this hypothesis, we find that weak governance firms, as measured by the G-index, have lower equity returns, worse operating performance, and lower firm value, but only so in non-competitive industries. When we examine the nature of the underlying agency cost, we find that weak governance firms have lower labor productivity, higher input costs, and make more value-destroying acquisitions, but, again, only so in non-competitive industries. We also find that weak governance firms in non-competitive industries are more likely to be targeted by activist hedge funds, suggesting that investors are taking actions to mitigate the inefficiency.
