This book draws together the seminal contributions to the literature on the nature of macroeconomics in open economies and illuminates the material. This is an essential guide to the subject for students.

This book surveys the theoretical issues that characterize the problem of reforming capital income taxes in an open economy. It explores the tax incentives and disincentives to investment in an open economy framework allowing cross-border portfolio and direct investment.

This paper highlights key issues pertinent for the understanding of international effects of domestic tax policies and of international tax harmonization. The analytical framework adopts the saving-investment balance approach to the analysis of international economic interdependence focusing on income, consumption, and international borrowing. A simulation model is developed that is richer in structure than the two period analytical model. The analytical and simulation frameworks are used to analyze the consequences of revenue-neutral conversions between income and consumption (VAT) tax systems, the international effects of budget deficits and public-debt management, and the effects of international tax harmonization. We demonstrate that the effects of such changes in the structure of taxes depend critically on international differences in saving and investment propensities.

The goal of the Mirrlees Review has been to identify what makes a good tax system for an open developed economy in the 21st century and to suggest how the UK tax system could be reformed to move in that direction. As an integral part of the Review, this volume brings together thirteen studies of different dimensions of tax design, plus associated commentaries. These were commissioned from IFS researchers and other international experts, to be of interest and value in their own right, as well as to provide inspiration for the final report of the Review, which is published as a separate volume, Tax by Design. The Commission's work was directed by: Tim Besley Richard Blundell Malcolm Gammie James Poterba The Commission's editorial team: Stuart Adam Stephen Bond Robert Chote Paul Johnson Gareth Myles

This paper articulates and, using newly-assembled data, explores how international taxation affects aggregate tangible cross-border investment. Spillovers from statutory tax rates abroad seem: As sizable as effects from the host’s rate; larger than previous consensus values (attributed to a systematic bias from FDI data); and consistent with ‘implicit’ profit shifting through real investment (rather than ‘paper’ profit shifting). Contrary to much policy discussion, the results also imply that: Host countries’ marginal effective tax rates have at best a weak effect on real investment; those elsewhere have none; and, applied to the prospective global minimum tax, inward tangible investment in most sample countries will increase.

This paper examines the main distortions of the U.S. corporate income tax (CIT), focusing on its international aspects, and proposes a set of reforms to alleviate them. A bold reform to replace the CIT with a corporate-level rent tax could induce efficiency-enhancing reform of the international tax system. Since fundamental reform is politically difficult, this paper also proposes an incremental reform that would reduce tax expenditures, reduce the CIT rate to 25-28 percent, and impose a minimum rent tax on foreign earnings. Finally, this paper analyzes empirically the likely impact of the incremental on corporate revenues outside the U.S.: Though a U.S. rate cut would likely lower revenues elsewhere, implementation of a strong minimum tax could more than offset that effect for most countries with effective tax rates above 15 percent.
