The present paper attempts to demonstrate that finding an appropriate trade-off between direct and indirect taxes can help smooth policy makers’ way through reconciling the contradictory notions of equity and efficiency. Our theoretical and empirical analysis is based on the assumption that...

This study investigates how strategic tax transfer pricing of a multinational company (MNC) and two tax authorities in different countries affects production and tax avoidance decisions at the firm level and tax revenues at the country level. We employ a game-theoretical model to analyze the...

This paper investigates the incentives for countries to implement and maintain the global minimum tax introduced by the G20/OECD’s Inclusive Framework 2021 agreement: Pillar 2. It argues that the agreement has sufficient elements to create incentives for large headquarters countries to...

This paper studies the effects of globalization on the ability of governments to generate tax revenues for the financing of national welfare states. In this context, it summarizes the theoretical predictions of various economic models of tax competition between countries and discusses the role...

Excess profit taxes (EPTs) emerge as an option to contribute to the extra needed revenues, avoiding a general increase in corporate tax rates, while having the prospect to serve as a gateway to converge toward a permanent efficient rent tax instaed of the corporate income tax. General unilateral...

This paper studies how the global minimum tax shapes national tax policies and welfare in a formal model of international tax competition with heterogeneous countries. The net welfare effect is generally ambiguous from the perspective of non-havens. On the one hand, the global minimum tax raises...

The recent international agreement on a minimum effective corporate tax rate marks a profound change in global tax arrangements. The appropriate level of that minimum, however, has been, and remains, extremely contentious. This paper explores the strategic responses to a minimum tax, which the...

A Theory of International Taxation combines qualitative and quantitative analyses to shed light on the shaping of the international tax regime (ITR) over the last century. It offers a theory of the ITR as the product of the strategic interaction between three small groups: international...

Anfang 2021 hat die Europäische Kommission den formalen Prozess zur Entwicklung eines stabilen regulatorischen und steuerlichen Rahmens zur Bewältigung der Herausforderungen der digitalen Wirtschaft wieder aufgenommen. Bereits 2018 wollte die Europäische Kommission eine politische Einigung...

As of the beginning of 2021, the European Commission has restarted the formal process to develop a stable regulatory and tax framework to address the challenges of the digital economy. In 2018, the European Commission initially intended to gain political agreement on a Digital Services Tax (DST)...

Based on the agreed Pillar 1 threshold of profitability of 10% (and given that financial and extractive companies are excluded), then only 78 of the world’s 500 largest companies will be affected. If the proportion of profit above this threshold liable to Amount A is set to 20% (from the...

We consider a world in which countries apply optimal taxes on mobile capital and savings (like in Bucovetsky and Wilson, 1991). Firms and savers may underreport income in order to avoid or evade taxation. We show that, even in the presence of underreporting, the equilibrium under tax competition...

The paper highlights key considerations necessary for the analysis of international tax competition and the desirability of international tax harmonization. The analysis of a Nash-Cournot international tax competition is carried out for (1) competing countries that cannot exercise significant...

The United States implements much of its social policy through the income tax laws. The Code is rife with tax expenditures for education, housing, community economic development, retirement savings, and health care to name a few. But the IRS is not an agency with expertise in any of these areas...

The integration of world capital markets carries important implications for the design and impact of tax policies. This paper evaluates research findings on international taxation, drawing attention to connections and inconsistencies between theoretical and empirical observations. Diamond and...

Opening Europe's borders in 1993 makes the allocation of resources more vulnerable to differences in the national tax rates. The first part of the paper demonstrates that direct consumer purchases will imply distortions resulting from diverging VAT rates and it clarifies why the frequently cited...

In a previous paper I described how the tax design called the X Tax would facilitate an international tax system free of many of the complexities and avoidance opportunities plaguing the existing international tax regime and also have neutrality properties generally deemed desirable. A choice...

Should a subset of member states of a federation be allowed to form a sub-union on some policy issue? When centralization is not politically feasible, allowing an enhanced cooperation agreement among a subset of countries permits the latter to gain benefits which would otherwise be lost....

Using a human capital based growth model, we show the essential role of labor mobility and cross-country tax harmonization in equalizing income levels of countries that start off from different initial income positions. Knowledge spillovers cum labor mobility are the driving forces behind the...

Theory predicts that strategically-determined tax rates induce negative externalities across countries in relative prices, the wealth distribution and tax revenue. This paper studies the interaction of these externalities in a dynamic, general equilibrium environment and its effects on...

We show that agglomeration forces can reverse standard international-tax-competition results. Closer integration may result first in a race to the top' and then a race to the bottom, a result that is consistent with recent empirical work showing that the tax gap between rich and poor nations...

To what degree will the recent free-trade agreement create pressure on the U.S. and Canada to modify, and perhaps harmonize, their tax systems? What will be the implications of the more extensive policy changes now going on within the E.C.? This paper examines the types of pressures for reform...

This paper is an introductory chapter to a book that brings together 22 of my papers written between 1965 and 1981. The chapter provides a summary of each paper and a more general discussion of the role of taxation in influencing the process of capita1 accumulation. The four sections of the book...

This paper investigates regulation on corporate income taxation with multinationals and transfer pricing. We recommend full cooperation within the EU if profit shifting costs are sufficiently low and cannot be influenced to a large extend. Otherwise, high profit shifting costs or the potential...

This paper shows how the distribution of the ownership of multinational companies and the labour market conditions, especially the wage formation process, influence the outcome of interjurisdictional tax competition and coordination. In particular, it sets forth that equilibrium corporate tax...

The paper analyzes the effects of a regionally coordinated profit tax in a model with three active countries, one of which is not part of the union, and a globally mobile firm. We show that regional tax coordination can lead to two types of welfare gains. First, for investments that would take...

This paper shows that under imperfect competition the welfare effects of indirect tax harmonization may depend crucially on whether taxes are levied by the destination or the origin principle. In a standard model of imperfect competition, while harmonization always makes at least one country...

Tax competition for mobile capital can undermine the attempts of governments to redistribute income from rich to poor. I study whether international tax coordination can alleviate this problem, using a general equilibrium model synthesizing recent contributions to the tax competition literature....

The paper employs a standard model of dynamic price competition to study how international principles of value-added taxation affect the stability of collusive agreements when producers in an international duopoly agree not to export into each others's home market and tax rates differ across...

The paper considers governments' public procurement decision as a way of influencing industry structure. In a federation in which capital is mobile and capital taxation is harmonized, a home bias in public procurement can potentially be explained as an effort to increase the capital intensity of...

If countries anticipate Bertrand competition in tax rates, they may expend effort that makes some of their tax payers less mobile or increases the mobility of tax payers elsewhere. I provide piecemeal evidence on what activities countries use. I analyse how such activities interact with Bertrand...

Basic economic theory identifies a number of efficiency gains that derive from international capital mobility. But just as free trade in goods, there is no guarantee that capital mobility makes everyone better off. Consequently, capital mobility may be politically unsustainable even though it...

This paper aims to contribute to the European policy debate on corporate income tax reform in three ways. First, it takes a step back to review the performance of the CIT in Europe over the past several decades and the important role played by MNEs in European economies. Second, it analyses...

Since its creation, the EU has targeted tax harmonization to protect the single market and avoid capital outflow to regions that have lower tax rates. However, despite repeated attempts, complete convergence has not yet been achieved. Using the effective tax rate, the statutory tax rate, and the...

The Inclusive Framework of the OECD/G20 currently discusses the internationally coordinated introduction of effective minimum taxes on multinational firm profits. This so-called GLOBE (global anti-base erosion) proposal is inspired by the GILTI and BEAT regimes of the 2017 US tax reform. It...
