Equity Misvaluation and Default Options

We study whether default options are mispriced in equity values by employing a structural equity valuation model that explicitly takes into account the value of the option to default (or abandon the firm) and uses firm‐specific inputs. We implement our model on the entire cross section of stocks and identify both over‐ and underpriced equities. An investment strategy that buys undervalued stocks and shorts overvalued stocks generates an annual four‐factor alpha of about 11% for U.S. stocks. The model's performance is stronger for stocks with a higher value of the default option, such as distressed or highly volatile stocks.     

Empirical Evidence of Risk Shifting in Financially Distressed Firms

This paper provides evidence of risk‐shifting behavior in the investment decisions of financially distressed firms. Using a real options framework, I show that shareholders' risk‐shifting incentives can reverse the expected negative relation between volatility and investment. I test two hypotheses that are consistent with risk‐shifting behavior: (i) volatility has a positive effect on distressed firms' investment; (ii) investments of distressed firms generate less value during times of high uncertainty. Empirical evidence using 40 years of data supports both hypotheses. I further evaluate the effect of various firm characteristics on risk shifting, and estimate the costs of the investment distortion.
