It is a well-known result in economics that land value taxation is efficient since it does not distort the supply of the tax base. Considering only efficiency, land value should thus be fully taxed. Using optimal taxation theory with heterogeneous households, we show that it may be optimal not...

This paper assesses a possible explanation for the global downward trend in top personal income tax rates over the last decades: globalization and the related tax evasion and avoidance opportunities could have raised elasticities of taxable income, which would imply lower optimal tax rates. The...

This paper discusses the theory and practice of tax design to achieve an efficient and equitable outcome, i.e. in support of inclusive growth. It starts with a discussion of the key principles from tax theory to guide practical tax design. Then, it elaborates on more granular tax policy,...

This paper provides an overview of the key economic factors that shape tax policy reform in many high-income countries, developing countries, and/or transition economies. The paper describes and evaluates global and regional developments with respect to tax rates and revenue ratios over the last...

In a recent paper Professor Dixit criticized the argument that when collection lags characterize tax systems, recourse to inflationary finance should be minimized. He argued that, in such case, rather than minimizing recourse to inflationary finance, the rates of the commodity taxes should be...

The paper analyzes the wage-employment effects of replacing unemployment benefits by negative income taxes. It first surveys the major equity and efficiency effects of unemployment benefits versus negative income taxes, and summarizes the salient features of many European unemployment benefit...

This paper provides an overview of the design of means-tested Guaranteed Minimum Income schemes, which constitute an important component of social protection systems in European countries. It discusses how key design features differ across countries, including how countries balance the primary...

A tax on gross assets has been introduced in some developing countries where several factors (most notably, high inflation) enabled apparently viable enterprises to report losses for income tax purposes. The idea of a tax on the value of assets, rather than on the income that the assets...

Following renewed academic and policy interest in the destination-based principle for taxing profits-particularly through a destination-based cash flow tax (DBCFT)-this paper studies other forms of efficient destination-based taxes. Specifically, it analyzes the Destination-Based Allowance for...

The recent international agreement on a minimum effective corporate tax rate marks a profound change in global tax arrangements. The appropriate level of that minimum, however, has been, and remains, extremely contentious. This paper explores the strategic responses to a minimum tax, which—the...
