Measuring the Redistributive Capacity of Tax Policies

Authors: Charles Vellutini & Juan Carlos Benitez

This paper presents a novel technique to measure and compare the redistributive capacity of observed tax (or transfer) policies. The technique is based on income distribution simulations and controls for differences in pre-tax income distributions. It assumes that the only information on the pre-tax distribution available in each country-year is the Gini coefficient and the mean (GDP per capita). We illustrate the technique with an application to the personal income tax, using a dataset of 108 countries over the 2007-2018 period.

Pareto-Improving Minimum Corporate Taxation

Authors: Shafik Hebous & Michael Keen

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 policy objective being to change the rules of tax competition game–—are critical for assessing the design and welfare impact of, and prospects for, this fundamental policy innovation. Analysis and calibration plausibly suggest sizable scope for minima that are Pareto-improving, benefiting low as well as high tax countries, over the uncoordinated equilibrium.

Natural Resource Taxation in Mexico: Some Considerations

Author: Alpa Shah

Mexico has large extractive industries and it traditionally has raised sizable fiscal revenues from the oil and gas sector. A confluence of factors—elevated commodity prices, financial challenges of the state-owned oil company Pemex, and revenue needs for financing social and public investment spending over the medium term—suggest that a review of Mexico’s taxation regimes for natural resources would be opportune, against the backdrop of a comprehensive approach to tackling Mexico’s challenges. This paper identifies opportunities for redesigning mining taxation to increase somewhat the revenue intake while maintaining the favorable investment profile of the sector. It also discusses recent reforms to the oil and gas fiscal regime and future reform considerations, with attention to the attractiveness of investment on commercial terms—an issue that should be placed in the context of an overall reform of Pemex’s business strategy and possibly of the energy sector more generally.

Social Spending in Mexico: Needs, Priorities and Reforms

Authors: Swarnali A Hannan, Juan Pablo Cuesta Aguirre & David Bartolini

Poverty in Mexico was high before the COVID-19 pandemic and has been exacerbated by the pandemic, with significant variation across states. Education losses from the pandemic are likely to be large and worsen pre-existing disparities; unless mitigated soon, they could contribute to heightened scarring over the medium term. Using state-level and cross-country comparisons, this paper reviews key social programs as well as priorities in education and health. It finds that higher spending and improved design of social programs (e.g., better targeting) would reduce socioeconomic gaps, mitigate scarring risks, and foster inclusive growth.
