The U.S. Tax Program for Swiss Banks is a very significant part of the recent history of the Swiss financial industry. It has accelerated the transformation of the Swiss banking industry from a system that relied on bank secrecy to a much more compliant one. It was also rather costly for the...

We document that the first leak of customer information from a tax haven bank caused a sudden flight of deposits from tax havens and a sharp decrease in the market value of banks known to be assisting with tax evasion. The loss of market value was largest for the banks most strongly involved in...

We document that the first leak of customer information from a tax haven bank caused a significant decrease in the market value of Swiss banks known to be assisting with tax evasion and that the decrease was largest for the banks most strongly involved. These findings suggest that markets...

We study the effect of the first global multilateral standard for the automatic exchange of information (AEOI), the so called Common Reporting Standard (CRS), on cross border tax evasion. Employing newly available bilateral data on cross-border deposits, we find that the CRS induced a reduction...

​We show that firms led by politically partisan CEOs are associated with a higher level of corporate tax sheltering than firms led by nonpartisan CEOs. Specifically, Republican CEOs are associated with more corporate tax sheltering even when their wealth is not tied with that of shareholders...

We analyze the impact of exchange of information in tax matters in reducing international tax evasion between 1995 and 2018. Based on bilateral deposit data for 39 reporting countries and more than 200 counterparty jurisdictions, we find that recent automatic exchange of information frameworks...

While the public has noticed the need for the detection of potential tax loopholes and demands further improvement in the taxation of banks, there is scarce empirical evidence whether banks' degree of tax avoidance actually differs from that of non-banks. We try to close this gap by...

This paper examines whether managers of firms that engage in high levels of tax avoidance (TA) strategically reduce their financial statement readability (FSR) to mitigate the risk of exposing their TA strategies. On average, results are inconclusive, but mainly hold in the sample of firms with...

We analyze the effect of mandatory financial transparency on corporate tax avoidance. Capital Requirements Directive IV by the European Commission required multinational banks to publish key financial and tax data in the form of public Country-by-Country Reporting. We examine tax avoidance of...

We show that managers can significantly lower corporate borrowing costs by adjusting effective tax rates. While prior research suggests a positive linear relation between tax avoidance and cost of debt, we document a U-shaped relation in which bondholders reward “undersheltering” firms with...
