Daniel Shaviro (NYU) has posted More Revenues, Less Distortion? Responding to Cross-Border Tax Arbitrage on SSRN. Here is the abstract:

Transactions commonly known as cross-border tax arbitrages take advantage of inconsistencies between countries’ tax rules to achieve more favorable tax results than could have been achieved by investing just in one country. Examples include dual resident companies and double dip leases, in which clever structuring may enable a multinational enterprise to claim the same deduction in two countries. This article analyzes the national and worldwide welfare considerations that may be relevant to a country’s deciding whether to allow tax benefits that will be thus duplicated, taking into account strategic interactions with other countries. It also briefly discusses cross-border tax arbitrage in relation to tax harmonization and the proposed creation of multilateral tax institutions akin to the GATT and WTO.
