Not for Redistribution Dedication This book is dedicated to Gary Becker, in appreciation of his inspiring teaching and long-time support of my work on environmental taxes; as my thesis chairman in the early 1990s, he encouraged me to model carbon taxes. Gary had agreed to write an endorsement for this book before his untimely death, his main reserva- tion being the risk that environmental tax revenues might be overused for low- value spending.

Not for Redistribution Foreword The enormous improvement in global living standards over the past 100 years could not have happened without the energy derived from the world’s vast depos- its of fossil fuels. Yet, the intense use of energy derived from such sources has brought side effects that pose major social, political, and economic challenges. The imperative is now to find ways to diversify and reduce the use of energy while continuing to eliminate poverty and promote inclusive growth. Within its man- date, the Fund is playing a part in this discussion. Indeed, energy policies are not new territory for the Fund. We have been em- phasizing the large fiscal benefits from removing harmful fuel subsidies for many years, primarily with an eye to saving money for the taxpayer. However, as the external effects of energy use have reached a macrocritical level—whether from environmental degradation, higher food prices, or the threat of climate change— the Fund’s advice has also evolved. Policymakers face a wide array of options for meeting energy challenges. Given the powerful incentive effect that prices have on economic behavior, the applica- tion of basic tax principles is critical. “Getting prices right” means that taxes on fossil fuels should be set at a level such that energy prices reflect their associated environmental side effects. This economic principle is widely accepted; however, putting it into practice is by itself an intellectual challenge. Here lies the unique contribution of this book.
