Policymakers are struggling to accommodate cryptocurrencies within tax systems not designed to handle them; this paper reviews the issues that arise. The greatest challenges are for implementation: crypto's quasi-anonymity is an inherent obstacle to third-party reporting. Design problems arise...

The international agreement on a corporate minimum tax is a milestone in global corporate tax arrangements. The minimum tax disturbs the equivalence between otherwise equivalent forms of efficient economic rent taxation: cash-flow tax and allowance for corporate equity. The marginal effective...

In this study, we estimate the impacts of differences in international tax rates on the probability of choosing a location for an affiliate of a multinational firm. In particular, we distinguish between the tax sensitivity of Greenfield and M&A investments. Based on a novel firm-level dataset on...

Theory recommends aligning the tax treatment of debt and equity. A few countries, notably Belgium, have introduced an allowance for corporate equity (ACE) to achieve tax neutrality. We study the effects of adopting an ACE on debt financing, passive investment, and active investment of...

Following renewed academic and policy interest in the destination-based principle for taxing profits—particularly through a destination-based cash flow tax (DBCFT)—this paper studies other forms of efficient destination-based taxes. Specifically, it analyzes the Destination-Based Allowance...

We estimate the revenue implications of a Destination Based Cash Flow Tax (DBCFT) for 80 countries. On a global average, DBCFT revenues under unchanged tax rates would remain similar to the existing corporate income tax (CIT) revenue, but with sizable redistribution of revenue across countries....

We sketch a model according to which tax havens attract corporate income generated in corrupted countries. In our framework, tax havens have two opposite effects on welfare. First, tax havens' services have a positive effect on welfare through encouraging investment by firms fearing...
