Subordinated Debt,Market Discipline,and Bank Risk

This paper demonstrates that subordinated debt (subdebt thereafter) regulation can be an effective mechanism for disciplining banks. By reducing the chance that managers of distressed banks can take value‐destroying actions to benefit themselves, subdebt regulation may encourage banks to lower asset risk. Moreover, subdebt regulation and bank capital requirements can be complements for alleviating the banks’ moral hazard problems. To make subdebt regulation effective, regulators may need impose ceilings on the interest rates of subdebt, prohibit collusion between banks and subdebt investors, and require subdebt to convert into the issuing bank's equity when the government provides assistance to the bank.     

Lock‐In Effects in Relationship Lending: Evidence from DIP Loans

Do prior lending relationships result in pass‐through savings (lower interest rates) for borrowers, or do they lock in higher costs for borrowers? Theoretical models suggest that when borrowers experience greater information asymmetry, higher switching costs, and limited access to capital markets, they become locked into higher costs from their existing lenders. Firms in Chapter 11 seeking debtor‐in‐possession (DIP) financing often fit this profile. We investigate the presence of lock‐in effects using a sample of 348 DIP loans. We account for endogeneity using the instrument variable (IV) approach and the Heckman selection model and find consistent evidence that prior lending relationship is associated with higher interest costs and the effect is more severe for stronger existing relationships. Our study provides direct evidence that prior lending relationships do create a lock‐in effect under certain circumstances, such as DIP financing.     

The Risk‐Taking Channel of Monetary Policy in the U.S.: Evidence from Corporate Loan Data

To study the presence of a risk‐taking channel in the U.S., we build a comprehensive data set from the syndicated corporate loan market and measure monetary policy using different measures, most notably Taylor (1993) and Romer and Romer (2004) residuals. We identify a negative relation between monetary policy rates and bank risk‐taking, especially in the run up to the 2007 financial crisis. However, this effect is purely supply‐side driven only when using Taylor residuals and an ex ante measure of bank risk‐taking. Our results highlight the sensitivity of the potency of the risk‐taking channel to the measures of monetary policy innovations.     

Cross‐Border Bank M&As and Risk: Evidence from the Bond Market

The impact of cross‐border bank M&As on bank risk remains an open question. Though geographically diversifying bank M&As have the potential to reduce the risk of bank insolvency, they also have the potential to increase that risk due to the increase in risk‐taking incentives by bank managers and stockholders following these transactions. This paper empirically investigates whether cross‐border bank M&As increase or decrease the risk of acquiring banks as captured by changes in acquirers' yield spreads. This paper also investigates how differences in the institutional environments between bidder and target countries affect changes in yield spreads following M&A announcements. The study finds that bondholders, in general, perceive cross‐border bank M&As as risk‐increasing activities, unlike domestic bank mergers. Specifically, on average, yield spreads increase by 4.13 basis points following the announcement of cross‐border M&As. This study also finds that these yield spreads are significantly affected by the differences in investor‐protection and deposit insurance environments between the transacting countries. However, the study does not find that the regulatory and supervisory environment in the home countries of the transacting parties significantly affects the changes in yield spreads. The overall evidence suggests that regulators should judge the relative environment in both the home and the host countries in evaluating the associated risks of an active multinational financial institution and in setting the sufficiency of the banks' reserve positions.     

Does Social Capital Matter in Corporate Decisions? Evidence from Corporate Tax Avoidance

We investigate whether the levels of social capital in U.S. counties, as captured by strength of civic norms and density of social networks in the counties, are systematically related to tax avoidance activities of corporations with headquarters located in the counties. We find strong negative associations between social capital and corporate tax avoidance, as captured by effective tax rates and book‐tax differences. These results are incremental to the effects of local religiosity and firm culture toward socially irresponsible activities. They are robust to using organ donation as an alternative social capital proxy and fixed effect regressions. They extend to aggressive tax avoidance practices. Additionally, we provide corroborating evidence using firms with headquarters relocation that changes the exposure to social capital. We conclude that social capital surrounding corporate headquarters provides environmental influences constraining corporate tax avoidance.
