Abstract
This article examines the effectiveness and feasibility of some of the main proposals for financial taxes by analysing their economic rationale and impact and some related international trade law issues regarding their implementation. The advantages and disadvantages are considered in terms of their effect on risk mitigation, market liquidity and the provision of sustainable revenue. The article suggests that financial transaction taxes, especially those applied to currency transactions and exchange-traded and over-the-counter derivatives, could serve regulatory objectives while raising adequate revenue to assist governments in paying for the social costs of financial crises and providing global public goods.
