The tax rules of the United States and other countries have intended and unintended effects on the operations of multinational corporations, influencing everything from the formation and allocation of capital to competitive strategies. The growing importance of international business has led economists to reconsider whether current systems of taxing international income are viable in a world of significant capital market integration and global commercial competition. In an attempt to quantify the effect of tax policy on international investment choices, this volume presents in-depth analyses of the interaction of international tax rules and the investment decisions of multinational enterprises. Ten papers assess the role played by multinational firms and their investment in the U.S. economy and the design of international tax rules for multinational investment; analyze channels through which international tax rules affect the costs of international business activities; and examine ways in which international tax rules affect financing decisions of multinational firms. As a group, the papers demonstrate that international tax rules have significant effects on firms' investment and other financing decisions.

Several recent papers argue that corporate income taxes should not be used by small, open economies. With capital mobility, the burden of the tax falls on fixed factors (e.g., labor), and the tax system is more efficient if labor is taxed directly. However, corporate taxes not only exist but rates are roughly comparable with the top personal tax rates. Past models also forecast that multinationals should not invest in countries with low corporate tax rates, since the surtax they owe when profits are repatriated puts them at a competitive disadvantage. Yet such foreign direct investment is substantial. We suggest that the resolution of these puzzles may be found in the role of income shifting, both domestic (between the personal and corporate tax bases) and cross-border (through transfer pricing). Countries need cash-flow corporate taxes as a backstop to labor taxes to discourage individuals from converting their labor income into otherwise untaxed corporate income. We explore how these taxes can best be modified to deal as well with cross-border shifting.

The increasing globalization of economic activity is bringing an awareness of the international consequences of tax policy. The move toward the common European market in 1992 raises the important question of how inefficiencies in the various tax systems—such as self-defeating tax competition among member nations—will be addressed. As barriers to trade and investment tumble, cross-national differences in tax structures may loom larger and create incentives for relocations of capital and labor; and efficient and equitable income tax systems are becoming more difficult to administer and enforce, particularly because of the growing importance of multinational enterprises. What will be the role of tax policy in this more integrated world economy? Assaf Razin and Joel Slemrod gathered experts from two traditionally distinct specialties, taxation and international economics, to lay the groundwork for understanding these issues, which will require the attention of scholars and policymakers for years to come. Contributors describe the basic provisions of the U.S. tax code with respect to international transactions, highlighting the changes contained in the U.S. Tax Reform Act of 1986; explore the ways that tax systems influence the decisions of multinationals; examine the effect of taxation on trade patterns and capital flows; and discuss the implications of the opening world economy for the design of optimal international tax policy. The papers will prove valuable not only to scholars and students, but to government economists and international tax lawyers as well.

Leading economists and policymakers consider what economic tools are most effective in reversing the rise in inequality. Economic inequality is the defining issue of our time. In the United States, the wealth share of the top 1% has risen from 25% in the late 1970s to around 40% today. The percentage of children earning more than their parents has fallen from 90% in the 1940s to around 50% today. In Combating Inequality, leading economists, many of them current or former policymakers, bring good news: we have the tools to reverse the rise in inequality. In their discussions, they consider which of these tools are the most effective at doing so.

This volume brings together nine papers from a conference on international macroeconomics sponsored by the NBER in 1985. International economists as well as graduate students in the fields of global monetary economics, finance, and macroeconomics will find this an outstanding contribution to current research. It includes two commentaries for each paper, written by experts in the field, and Frenkel's detailed introduction, which serves as a reader's guide to the arguments made, the models employed, and the issues raised by each contributor. The studies analyze national fiscal policies within the context of the international economic order. Malcolm D. Knight and Paul R. Masson use an empirical model to show that fiscal changes in recent years in the United States, West Germany, and Japan have caused major disturbances in net savings and investment flows. Linda S. Kole uses a two-country simulation model to examine the effects of a large nation's expansion on exchange rates, interest rates, and the balance of payments. In other studies, Warwick J. McKibbin and Jeffrey D. Sachs discuss the influences of different currency regimes on the international transmission of inflation; Kent P. Kimbrough analyzes the interaction between optimal tax policies and international trade; Sweder van Wijnbergen investigates the interrelation of fiscal policies, trade intervention, and world interest rates; and Willem H. Buiter uses an analytical model to look at fiscal interdependence and optimal policy design. David Backus, Michael Devereux, and Douglas Purvis develop a theoretical model to investigate effects of different fiscal policies in an open economy. Alan C. Stockman looks at the influence of policy anticipation in the private sector, while Lawrence H. Summers shows the effects of differential tax policy on international competitiveness.
