This paper discusses the issue of profit shifting and "aggressive" tax planning by multinational firms. The paper makes two contributions. First, it provides some background information to the debate by giving a brief overview of existing empirical studies on profit shifting and by describing...

We study how short-selling pressure affects tax aggressiveness using the pilot program on short sales in Regulation SHO. Using a difference-in-differences approach, we find that higher short-selling pressure significantly reduces tax aggressiveness. To explain the reduction, we offer a simple...

We examine the shareholder response to heightened regulation of corporate tax planning advice through the covered opinions rules under U.S. Treasury Department Circular No. 230. These rules imposed extensive due diligence obligations and drafting requirements on tax professionals for a broad...

We investigate whether and how the federal judiciary affects corporate tax planning. We find that firms engage in less aggressive tax planning when Circuit Court and Tax Court judges are more liberal. This effect is economically significant and robust across various measures of tax planning. We...

This study examines whether corporate tax planning and financial reporting of income taxes vary systematically with CEO tenure. Using a CEO-firm fixed effects design, we find that the GAAP effective tax rate (ETR) is higher in the early years of the CEOs' tenure and lowest in the last year of...

We find that firms' tax planning exhibits strategic reactions: firms respond to changes in their industry-competitors' tax planning by changing their own tax planning in the same direction. We document evidence of these strategic reactions in two distinct research settings that entail an...

Our objective is to examine the ‘black box' of corporate tax risk management by providing unique insights into practitioners' tax risk perception, implemented tax risk management practices, and the internal dynamics leading to these practices. We perform our analysis based on 33 expert...

This study investigates whether expected economic growth is associated with corporate tax planning. We predict that higher expected economic growth increases the net present value of tax planning opportunities and thus increases investment in tax planning. Consistent with our prediction, we find...

I examine differences between effective tax rates (ETRs) and book-tax differences (BTDs) as alternative measures of corporate tax avoidance or tax aggressiveness. When BTDs are scaled by pretax income, the scaled BTD is statistically equivalent to the ETR. When BTDs are scaled by assets the...
