Abstract: Using data from the annual reports of over 100,000 subsidiaries of multinational enterprises (MNEs) from 55 countries between 2003 and 2012, the authors of this article investigate the impact of exchange-of-information agreements ("EOI agreements") on tax-motivated income shifting. Transparency created by the signing of EOI agreements is expected to reduce the tax-motivated shifting of income by multinational corporations. Whether such agreements affect the income-shifting behaviour of multinational corporations is an unanswered question. The authors find evidence that, on average, EOI agreements do have an impact on tax-motivated income shifting. Additionally, they find that more advanced, modern EOI agreements are associated with a larger decrease in tax-motivated income shifting compared to the impact of early EOI agreements. This evidence challenges the prevalent assumption in empirical studies that EOI agreements are homogeneous. Supplemental analyses suggest that factors that affect the information asymmetry between MNEs and tax authorities, such as corporations with high levels of intangibles and tax authorities with strong transfer-pricing rules and enforcement, can diminish or enhance the effectiveness of EOI agreements in moderating tax-motivated income shifting. The evidence provided by this study shows that consideration of the tax authorities' information environment and the substance of an EOI agreement is essential when assessing the impact of such an agreement on the tax behaviour of sophisticated taxpayers such as multinational corporations.
