This study examines the empirical evidence of risk-shifting behavior in large and small distressed firms. The main contributions include the extension of a previous study and the use of a more rigorous method to measure asset return and volatility. The results suggest that the risk-shifting problem is more significant for small firms due to their agency problems.

Comments onEmpirical Evidence of Risk Shifting Behavior in Large and Small Distressed Firms Yehning Chen National Taiwan University
Main Contributions • An extension of Eisdorfer (2008) • Eisdorfer (2008): For distressed firms, • Volatility↑ → Gains from risk-taking↑→ Investment↑ • This effect is more significant when volatility is higher • Contribution 1: the above effects are significant only for small firms because their agency problems are more serious • Contributions 2: for measuring asset return and volatility, use Duan (1994, 2000) rather than Merton (1974)
Comments • Very interesting idea: size (market capitalization) matters! Empirical results support the idea. Dependent: investment Dependent: ΔVolatility
Comments Why does size matter? A puzzle! Is the risk-shifting problem more serious for small firms? Not necessarily. (complexity, bargaining power, …) Size is rarely used as a proxy for agency problems (Smaller → Adverse selection↑→ Risk shifting↑? ) Wild guess: size may be related to financial distress Given the same z-score: Larger firms → less likely to fail → less distressed → less likely to suffer risk-shifting 4
Comments Using Duan (1994, 2000) to calculate asset return and volatility Plus: More rigorous conceptually Minus: Results less comparable to Eisdorfer (2008) How significant are the improvements? If claim the improvements are important → Need to show what differences it makes 5
Comments Some minor points Style: too similar to Eisdorfer (2008) in format (tables, variables used, hypotheses, paragraphs…) Results in Table 7 (Cost of risk-shifting) are not significant Impact of investment on debt value is insignificant For small distressed firms, the overinvestment problem reduces value of debt only by 0.97% 6
Comments Some minor points Results against the intuitions (1) z-score↑→ risk-shifting↓→ marginal return of investment↑ Table 3 finds the opposite results (for large firms) (2) Secured debt↑, convertible debt↑, or regulated industry → Risk-shifting problem should be less serious. Table 5 finds the opposite results 7
