This paper examines how the effects of dividend taxation on the cost of new equity funds depend on whether or not shareholders can recover their original equity injections without being subject to the dividend tax. We point out the alternative assumptions in the literature on this, and we...

The Savings Directive has been celebrated as a major political break-through in coordinating taxation in Europe. Against this background, the present paper evaluates the real-world effects of this directive. The directive has left a loophole by providing grandfathering (exemption from...

Until 2009, the United Kingdom operated a system of worldwide taxation. Taxation of foreign income was deferred until repatriated as dividends, leaving UK-owned multinational firms the possibility of avoiding UK taxation by delaying dividend payments and keeping earnings abroad. In 2009, the UK...

The present study provides estimates of the Effective Marginal Tax Rates (EMTRs) for a sample of 17 OECD countries and 11 manufacturing sectors in a single framework encompassing capital, labour and energy taxes. Our cross-country/cross-sector approach allows us comparing the incentives provided...

We study the optimal nonlinear income tax problem with multidimensional individual characteristics on which taxes cannot be conditioned. We obtain an optimal tax formula that generalizes the standard one by averaging, with specific weights, the sufficient statistics of individuals who earn the...
