Policymakers will not accept forceful decarbonisation policies if they lead to visibly increasing inequality within their societies. The distributive effects of climate policies need to be addressed. This report provides a selective review of recent academic literature and experience on the distributional effects of climate policies.
Most people would agree that it makes sense to tax a company that pollutes in a way that directly reflects the amount of environmental and social damage it has done. Yet in practice, such taxes are fraught with difficulty and have far-reaching implications. A company facing a new tax may lay off workers, for example, exacerbating an unemployment problem. This volume focuses on such external issues and examines in detail the trade-offs involved in designing policies to deal with environmental problems. Reflecting the broad nature of the subject, the contributors include leading economists in the areas of public finance, industrial organization, and trade theory, as well as environmental economists. Integrating both theoretical and empirical methods, they examine environmental policy design as it relates to location decisions, compliance costs, administrative costs, effects on research and development, and international factor movements. Shedding light on an extraordinarily complex and important topic, this collection will be of interest to all those involved in designing effective environmental policy.
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 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.
Distributional cost-effectiveness analysis aims to help healthcare and public health organizations make fairer decisions with better outcomes. It can provide information about equity in the distribution of costs and effects - who gains, who loses, and by how much - and the trade-offs that sometimes occur between equity and efficiency. This is a practical guide to methods for quantifying the equity impacts of health programmes in high, middle, and low-income countries. The methods can be tailored to analyse different equity concerns in different decision making contexts. The handbook provides both hands-on training for postgraduate students and analysts and an accessible guide for academics, practitioners, managers, policymakers, and stakeholders. Part I is an introduction and overview for research commissioners, users, and producers. Parts II and III provide step-by-step guidance on how to simulate and evaluate distributions, with accompanying spreadsheet training exercises. Part IV concludes with discussions about how to handle uncertainty about facts and disagreement about values, and the future challenges facing this growing field. Book jacket.
Economists have had much to say about the impact of economic policies on growth, but little on their distributional consequences and poverty impact. The reorientation of development policy from structural adjustment to poverty reduction as the central objective thus called for new tools to examine distributional change. This book analyzes the poverty and distributional impact of policy changes and external shocks in three case studies from Latin America: Trade liberalization in Colombia and Brazil, and the gas boom in Bolivia. It uses an innovative approach that combines computable general equilibrium and microsimulation models. The country applications illustrate that distributional consequences depend very much on the nature of the shock or policy change as well as the characteristics of the country in question. The book issues a warning against policy prescriptions being based on oversimplifying assumptions and models.
Microeconomic Simulation Models for Public Policy Analysis, Volume 1: Distributional Impacts is a collection of papers presented at a conference of the same title held in Washington, D.C. in March 1978. This collection discusses extended micro data models for first-round distributional analysis, models that incorporate behavioral responses to the policies being stimulated, models of macroeconomics, and models that have sectorial or regional impacts. One paper explains that increasing support for the negative income tax scheme can result in bigger increase in the budgetary cost of the program itself. Another paper evaluates the Kasten, Greenberg, Betson program as useful for policymakers to determine the distributional consequences of any proposed changes in policy in welfare reforms. With the oil embargo and energy crisis in the U.S., one author presents a model to measure the impacts these events have on energy consumers, especially on the lower-income group. Such model employs a comprehensive human resources data system that measures the distributional impacts of energy policies. This book is beneficial for policy makers and regulators involved in economic and public services. This book can also help sociologists and academicians in the field of political science and developmental studies.
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.
The 2015 Millennium Development Goal to reduce by 50 percent the share of the world's population living in extreme poverty was met early. The number of individuals in developing countries who live in extreme poverty had decreased from 43 percent in 1990 to 21 percent by 2010. Yet, with 1.2 billion people still struggling today, we have a long way to go. What can we learn from the recent success of reducing extreme poverty? Understanding Changes in Poverty brings together different methods to decompose the contributions to poverty reduction. A simple approach quantifies the contribution of changes in demographics, employment, earnings, public transfers, and remittances to poverty reduction. A more complex approach quantifies the contributions to poverty reduction from changes in individual and household characteristics, including changes in the sectoral, occupational, and educational structure of the workforce, as well as changes in the returns to individual and household characteristics. Understanding Changes in Poverty implements these approaches and finds that labor income growth--that is, growth in income per worker rather than an increase in the number of employed workers--was the largest contributor to moderate poverty reduction in 21 countries experiencing substantial reductions in poverty over the past decade. Changes in demographics, public transfers, and remittances helped, but made relatively smaller contributions to poverty reduction. Further decompositions in three countries find that labor income grew mainly because of higher returns to human capital endowments, signaling increases in productivity, higher relative price of labor, or both. Understanding Changes in Poverty will be of particular relevance to development practitioners interested in better understanding distributional changes over time. The methods and tools presented in this book can also be applied to better understand changes in inequality or any other distributional change.
This paper investigates the response of consumer price inflation to changes in domestic fuel prices, looking at the different categories of the overall consumer price index (CPI). We then combine household survey data with the CPI components to construct a CPI index for the poorest and richest income quintiles with the view to assess the distributional impact of the pass-through. To undertake this analysis, the paper provides an update to the Global Monthly Retail Fuel Price Database, expanding the product coverage to premium and regular fuels, the time dimension to December 2020, and the sample to 190 countries. Three key findings stand out. First, the response of inflation to gasoline price shocks is smaller, but more persistent and broad-based in developing economies than in advanced economies. Second, we show that past studies using crude oil prices instead of retail fuel prices to estimate the pass-through to inflation significantly underestimate it. Third, while the purchasing power of all households declines as fuel prices increase, the distributional impact is progressive. But the progressivity phases out within 6 months after the shock in advanced economies, whereas it persists beyond a year in developing countries.
