Abstract
We exploit the new multinational corporations' country-by-country reporting data with unparalleled country coverage to study profit shifting to tax havens. We show that a logarithmic function is preferable to linear and quadratic ones for modelling the extremely non-linear relationship between profits and tax rates.
Using this methodology, we reveal that multinational corporations shifted US$1 trillion of profits in 2016 and that those headquartered in the United States and China did so most aggressively. We establish that the Cayman Islands is the largest tax haven, whereas countries with lower incomes tend to lose more tax revenue relative to total tax revenues.
