The World Bank has partnered with the Commitment to Equity Institute at Tulane University to implement their diagnostic tool—the Commitment to Equity (CEQ) Assessment—designed to assess how taxation and public expenditures affect income inequality, poverty, and different economic groups. The approach relies on comprehensive fiscal incidence analysis, which measures the contribution of each individual intervention to poverty and inequality reduction as well as the combined impact of taxes and social spending. The CEQ Assessment provide an evidence base upon which alternative reform options can be analyzed. The use of a common methodology makes the results comparable across countries. This volume presents eight country studies that examine the distributional effects of individual programs and policy measures—and the net effect of each country’s mix of policies and programs. These case studies were produced in the context of Bank policy dialogue and have since been used to propose alternative reform options.

This book develops a number of analytical models and presents empirical analyses of the equity and efficiency effects of existing indirect taxes from New Zealand. Potential tax reforms including environmental taxes are also examined and the methods presented can easily be adapted to deal with other countries. Policy debates are inevitably influenced by value judgements, which are seldom made explicit either by governments or those engaging in public discussion. By concentrating on the empirical orders of magnitude, and by examining the implications of adopting alternative value judgements, the findings of this book contribute towards rational policy debate, rather than relying on guesswork and rhetoric. The equity and efficiency effects of indirect taxes are examined in detail, using the central concepts of welfare changes, the excess burden of taxation, and money metric utility measures. The indirect taxes examined include a carbon tax designed to reduce carbon dioxide emissions. The Distributional Effects of Indirect Taxes develops widely applicable models and will therefore appeal to economists interested in public economics, tax policy, inequality measurement, welfare economics and tax modelling. Economists in government departments and international agencies interested in public finance and inequality and poverty measurement will also find much to engage them in this book, as will policymakers concerned with indirect and environmental tax policy, inequality, and welfare economics.

This book builds upon existing literature to simultaneously examine disparities in the distribution of environmental impacts of environmental policy and in the distribution of financial effects among households.

Addressing the poverty and distributional impacts of carbon pricing reforms is critical for the success of ambitious actions in the fight against climate change. This paper uses a simple framework to systematically review the channels through which carbon pricing can potentially affect poverty and inequality. It finds that the channels differ in important ways along several dimensions. The paper also identifies several key gaps in the current literature and discusses some considerations on how policy designs could take into account the attributes of the channels in mitigating the impacts of carbon pricing reforms on households.

Edited by Nora Lustig, the Commitment to Equity Handbook: Estimating the Impact of Fiscal Policy on Inequality and Poverty (Brookings Institution Press and CEQ Institute-Tulane University, 2nd edition, 2022) is a unique manual on the theory and practical methods to estimate the impact of taxation and public spending on inequality and poverty. In addition, the second edition covers frontier topics such as alternative approaches to measure the redistributive effect of education, health, and infrastructure spending. Policymakers, social planners, and economists are provided with a step-by-step guide to applying fiscal incidence analysis, illustrated by country studies. The 2nd edition of the Handbook has two volumes. Volume 1 is comprised of Part I, Methodology, describes what a CEQ Assessment© is and presents the theoretical underpinnings of fiscal incidence analysis and the indicators used to assess the distributive impact and effectiveness of fiscal policy. Part II, Implementation, presents the methodology on how taxes, subsidies, and social spending should be allocated. It includes a step-by step guide to completing the CEQ Master Workbook©, a multi-sheet Excel file that houses detailed information on the country’s fiscal system and the results used as inputs for policy discussions, academic papers, and policy reports. Part III, “Applications,” presents applications of the CEQ framework to low- and middle-income countries and includes simulations of policy reforms. In this 2nd edition, chapters 1, 6, and 8 have been significantly updated and two new country studies have been added to Part III. Parts IV (updated), V (new), and VI (new) are available online only. Part IV contains the CEQ Assessment’s main tools. Part V includes the databases housed in the CEQ Data Center on Fiscal Redistribution. Part VI contains the CEQ Institute’s microsimulation tools. Volume 2 (new) includes a collection of chapters whose purpose is to expand the knowledge and methodological frontiers to sharpen even further the analysis of fiscal policy’s redistributive impact. Topics include: alternative approaches to value in-kind education and health services; alternative methods to evaluate spending on infrastructure; corporate taxes and taxation on capital incomes; inter-temporal fiscal incidence and the redistributive consequences of social insurance pensions; fiscal redistribution, macroeconomic stability and growth; and, the political economy of fiscal redistribution.
