This paper studies an optimal tax problem for a small open economy where collecting taxes is costly. It is shown that, in the presence of collection costs modeled as an increasing function of the tax rate: (a) the standard rules of optimal commodity taxation (the Ramsey, the inverse elasticity,...

This paper discusses important tax policy issues facing developing countries today. It views tax policy from both the macroeconomic perspective, which focuses on broad questions such as the level and composition of tax revenue, and the microeconomic perspective, which focuses on certain design...

Like any tax, the VAT is vulnerable to evasion and fraud. But its credit and refund mechanism does offer unique opportunities for abuse, and this has recently become an urgent concern in the European Union (EU). This paper describes the main forms of noncompliance distinctive to a VAT, considers...

Like the theory of the second best that the 2006 congress marks, the VAT is now fifty years old. Judged by the extent and speed of its spread around the world, and the revenue that it raises, the VAT would seem to have been a remarkable success. Over the last few years, however, it has come...

This paper sets out some tools for understanding the performance of the value added tax (VAT). Applying a decomposition of VAT revenues (as a share of GDP) to the universe of VATs over the last twenty years, it emerges that developments have been driven much less by changes in standard rates...

This paper addresses two fundamental issues in indirect tax design. It first revisits the case for reduced rates on items especially important to the poor, establishing conditions under which even very crudely targeted spending measures better serve their interests. It then explores the welfare...

This paper examines tax policy and tax reforms in Uganda. Using household survey evidence, the paper identifies which taxes are progressive and investigates whether tax reforms have made the poor better or worse off. Household survey analysis reveals that some of the tax reforms implemented in...

Do reductions in capital income taxes attract foreign capital and, at the same time, foster economic growth? This paper examines the effect of capital income taxation on the international allocation of capital and on economic growth in a two-country overlapping generations model with endogenous...

Tax laws and administrations often treat different size firms differently. There is, however, little research on the consequences. As modeled here, oligopolists with different efficiencies determine the size distribution of firms. A government that maximizes a weighted sum of consumer surplus,...
