Business complexity and risk management: evidence from operational risk events in U. S. bank holding companies
How does business complexity affect risk management in financial institutions? The commonly used risk measures rely on either balance-sheet or market-based information, both of which may suffer from identification problems when it comes to answering this question. Balance-sheet measures, such as return on assets, capture the risk when it is realized, while empirical identification requires knowledge of the risk when it is actually taken.

Uncertainty, Stock Prices and Debt Structure: Evidence from the U.S.-China Trade War
Using the recent U.S.-China trade war as a laboratory, we show that policy uncertainty shocks have a significant impact on stock prices. This impact is less negative for firms that heavily rely on bank debt whereas non-bank debt does not have a mitigating effect. Moreover, the mitigating effect of bank debt is concentrated among zombie firms. A zombie firm that derives half of its capital from bank debt has no negative stock price reaction to increased uncertainty. These results are consistent with bank debt providing insurance for zombie firms in bad economic times.
Firm Debt Structure Can Mitigate Impact of Uncertainty Shock
We found evidence that the way a firm structures its debt can mitigate a significant amount of the negative effects from uncertainty shocks, especially for zombie firms.
