The theory of optimal taxation has often been criticized for being of little practical policy relevance, due to a lack of robust theoretical results. This paper argues that recent advances in optimal tax theory has made that theory easier to apply and may help to explain some current trends in...

The integration of world capital markets carries important implications for the design and impact of tax policies. This paper evaluates research findings on international taxation, drawing attention to connections and inconsistencies between theoretical and empirical observations. Diamond and...

The Organisation for Economic Co-Operation and Development (OECD) recently proposed an interest barrier to fight tax base erosion and profit shifting (BEPS). We use the introduction of such an interest deductibility restriction in Germany as a quasi-experiment and find significant corporate...

The theoretical literature suggests that when taking tax effects into account, debt ought to be preferable to equity. However, there are no uniform predictions of the size of this tax benefit (tax shield) in comparison to an opposing increasing cost of debt (especially insolvency costs). The...

The recent international agreement on a minimum effective corporate tax rate marks a profound change in global tax arrangements. The appropriate level of that minimum, however, has been, and remains, extremely contentious. This paper explores the strategic responses to a minimum tax, which the...

This study examines the effect of the interaction of dividend taxes and capital gains taxes on the sale of stock. Using a model of the new view of dividend taxation modified to incorporate realization-based capital gains and losses on stock, it shows that capital gains taxes increase the...

We consider a model in which business public services must be financed with either a source-based tax on mobile capital, such as a property tax, or a tax on production, such as an origin-based VAT and assess which of the two tax instruments is more efficient. In general, both a capital tax and a...

In general, both a capital tax and a...

We examine whether three tax system characteristics – required book-tax conformity, worldwide versus territorial approach, and perceived strength of enforcement – impact corporate tax avoidance across countries after controlling for firm-specific factors previously shown to be associated...

We propose a novel approach for studying optimal capital structure under the prevalent corporate income tax regime where full tax deductibility of interest is permitted. Then, following the OECD proposed BEPS (Base Erosion and Profit Shifting) framework, we impose an EBITDA-based limit on the...
