Tax Deductions Environmental Policy And The Double Dividend Hypothesis

Presents the paper "Tax Deductions, Environmental Policy, and the "Double Dividend" Hypothesis," written by Ian Parry and Antonio Bento in May 1999 for the World Bank. The authors find that incorporating tax-favored consumption in models of environmental tax swaps may overturn key results from earlier studies.

Recent studies find that environmental tax swaps typically exacerbate the costs of the tax system and therefore do not produce a double dividend. This paper extends previous models by incorporating tax-favored consumption goods. In this setting, the efficiency gains from recycling environmental tax revenues are larger because preexisting taxes distort the consumption bundle, in addition to factor markets. A genuine double dividend is then found.Parry and Bento find that incorporating tax-favored consumption in models of environmental tax swaps may overturn key results from earlier studies. In particular, a revenue-neutral pollution tax (or auctioned permits) can produce a substantial double dividend by reducing both pollution and the costs of the tax system. The second dividend arises because the welfare gain from using environmental tax revenues to cut labor taxes is much larger when labor taxes also distort the choice among consumption goods. Indeed (ignoring environmental benefits), the overall costs of a revenue - neutral pollution tax are negative in the benchmark simulations, at least for pollution reductions up to 17 percent, and possibly up to 42 percent.In addition, Parry and Bento show that the presence of tax-favored consumption may drastically increase the efficiency gain from using (revenue-neutral) emissions taxes (or auctioned emissions permits) rather than grandfathered emissions permits.This paper - a product of Infrastructure and Environment, Development Research Group - is part of a larger effort in the group to study regulatory policies in a second-best setting.

Recent studies find that environmental tax swaps typically exacerbate the costs of the tax system and therefore do not produce a "double dividend". We extend previous models by incorporating tax-favored consumption goods (e.g. housing, medical care). The efficiency gains from recycling environmental tax revenues are therefore larger because pre-existing income taxes distort both consumption decisions and factor markets. In this setting a revenue-neutral emissions tax (or auctioned permits) produces a double dividend. Moreover, the overall costs of environmental tax swaps are negative, for modest emissions reductions. The efficiency gains from emissions taxes over grandfathered permits are also much larger than previously recognized.

This volume contains 31 contributions from Goulder (economics, Stanford U.) and other scholars on the interactions between environmental policy initiatives and distortionary taxes (such as income and sales taxes). Coverage includes such topics as tradeable emissions permits, the substitution of taxes on pollution for existing distortionary taxes, and the effects of environmental policies on income distribution. With the exception of Agnar Sandmo's 1975 paper on the optimal setting of commodity taxes, the contributions have all been published in various economic journals no earlier than 1994.

A rigorous and innovative approach for integrating environmental policies and fiscal reform for the U.S. economy. Energy utilization, especially from fossil fuels, creates hidden costs in the form of pollution and environmental damages. The costs are well documented but are hidden in the sense that they occur outside the market, are not reflected in market prices, and are not taken into account by energy users. Double Dividend presents a novel method for designing environmental taxes that correct market prices so that they reflect the true cost of energy. The resulting revenue can be used in reducing the burden of the overall tax system and improving the performance of the economy, creating the double dividend of the title. The authors simulate the impact of environmental taxes on the U.S. economy using their Intertemporal General Equilibrium Model (IGEM). This highly innovative model incorporates expectations about future prices and policies. The model is estimated econometrically from an extensive 50-year dataset to incorporate the heterogeneity of producers and consumers. This approach generates confidence intervals for the outcomes of changes in economic policies, a new feature for models used in analyzing energy and environmental policies. These outcomes include the welfare impacts on individual households, distinguished by demographic characteristics, and for society as a whole, decomposed between efficiency and equity.

An important topic in environmental economics is how to reduce carbon dioxide emissions in order to reduce the threat of global warming. For this purpose, some countries levy environmental taxes. Often, such taxes can result in a second dividend if revenues are used for other governmental purposes such as the reduction of unemployment or the reduction of taxes. Can Germany realistically earn this "double dividend"? Based on a theoretical model, Scholz performs numerical simulations to find out whether environmental taxes have positive effects on households (differentiated by income groups) and firms (differentiated by technologies). Scholz finds that most effects on employment are not large enough to warrant the term "double dividend" and concludes that it is better to levy environmental taxes only for environmental objectives. This study will be of interest to scholars and students specializing in environmental economic issues as well as to international organizations and research institutes in economics.

This paper reviews recent literature on the macroeconomic effects of environmental taxes. It attempts to delineate the conditions under which a cleaner environment is compatible with attaining macroeconomic objectives, such as more employment and economic growth. The analysis reveals that an environmentally motivated fiscal reform—using the revenues from environmental taxes to cut labor taxes—may yield employment and environmental dividends if the tax burden can be shifted to agents outside the labor market, such as capitalists, transfer recipients, and foreigners. A cleaner environment and a higher rate of economic growth go hand in hand if the environment is considered an important public input into production.

'In looking at the effects of ecological tax reform on allocation, this book addresses a very important issue. The results are interesting and have significant policy implications.' - Glenn Feltham, Canadian Tax Journal 'The book contains an excellent analysis of how environment taxation affects large countries that are highly integrated in world capital markets.' - Lans Bovenberg, CPB Netherlands Bureau for Economic Policy Analysis, The Netherlands The twin benefits of improving environmental quality and reducing tax distortions through the recycling of environmental tax proceeds prove an attractive policy objective. This book analyses the use of the double dividend concepts for evaluating ecological tax reforms. The author aims to analyse unilateral environmental policy measures thoroughly and to assess under which conditions a double dividend can be achieved. The analysis is undertaken in the context of international capital mobility and cross-border externalities. He also includes a discussion of an empirically relevant example for an ecological tax reform scenario in Germany - the DIW proposal.
