We develop a theory of tax reforms for a setting with multi-dimensional heterogeneity amongst taxpayers and multiple economic decisions that are all subject to fixed and variable costs. The theorems in this paper provide a complete characterization of the conditions under which Pareto- or...

This paper discusses tax policy measures to reduce corporate tax avoidance by extending taxation in the source country without imposing double taxation. We focus on four options: Bilaterally restricting interest and royalty deductibility, introducing an inverted tax credit system, levying...

The Mirrlees Review recommends that commodity taxation should in general be uniform, but with some goods consumed in conjunction with labour supply (such as child care) left untaxed. This paper examines the validity of this claim in an optimal income tax framework. Contrary to the recommendation...

This paper aims to provide a perspective on the ideal tax system using insights from optimal-tax theory supplemented with empirical evidence. These insights are applied to actual policy questions regarding the progressiveness of the labor income tax, in-work tax credits, the design of the...

This paper tests a version of Barro’s tax-smoothing model, which assumes intertemporal optimization by a government seeking to minimize the distortionary costs of taxation, using Pakistan and Sri Lankan data for 1956-95 and 1964-97, respectively. The empirical results indicate that...
