Tax reforms and the capital structure of banks

This paper studies the link between corporate income tax (CIT) reforms and domestic banks’ financing decisions. We use a dataset of CIT reforms and estimate the effect of tax rate changes on leverage, dividend policies and earnings management of banks. The results suggest that taxation influences all three variables. Leverage increases with the CIT rate in the first three years after the reform. The reason is that the statutory CIT rate determines the value of the debt tax shield. A higher tax rate increases incentives to use debt finance when interest payments are deductible from the CIT base. The tax effects we find are statistically and economically significant but considerably lower than those found in previous research. Also, dividend pay-outs increase after an increase in CIT rates. This could indicate that banks actively manage their pay-out policies around tax reforms and adjust their capital structure with changes in dividends. Furthermore, banks increase loss loan reserves in anticipation of tax rate cuts since losses become less valuable with lower CIT rates.     

Online RPM and MFN Under Antitrust Law and Economics

The legal framing of a firm’s pricing strategy can determine whether it constitutes online resale price maintenance (RPM) or online most favored nation (MFN). Together, cases that involve online RPM and MFN can be viewed as a natural experiment of how antitrust economics and law may adapt to an online world. Thus far, legal theories that have been inconsistent with economic theories have dictated enforcement across jurisdictions, which has led to confusion that thwarts potentially efficient business practices. This paper distinguishes issues of online RPM from traditional RPM and online RPM from online MFN. We apply the economics learning to RPM and analyze the antitrust cases of online RPM and MFN to date in the United States, Europe, and Australia. Finally, we offer policy recommendations that reduce the confusion in current legal doctrine.     

The Impact of Mergers on Quality Provision: Evidence from the Airline Industry

We examine how mergers affect quality provision by analyzing five U.S. airline mergers, focusing on on‐time performance (OTP). We find that airline mergers have minimal negative impacts on OTP, and likely result in long‐run improvements due to efficiencies. Importantly, we show that this finding is not driven by post‐merger changes in price that could affect OTP. Consequently, at least in the case of airlines, policymakers should not, as a rule, fear the negative quality effects of mergers.
