On the political economics of tax reforms: survey and empirical assessment

Political constraints and incentives are the true driver of tax reforms. This paper reviews the political economics literature on personal income tax systems and reforms to see how political mechanisms help explain tax reforms. We take some of the implications of these theories to the data using LABREF, a database that identifies labor tax reforms in the European Union for the period 2000–2007, and control for economic and labor market factors. We find that political variables carry more weight than economic variables, and we show empirical regularities that support political economy theories. We also find that governments tended to reform more in better economic times, engaging in pro-cyclical behavior.     

GARCH modelling of banking integration in the Eurozone

We investigate the progress of integration in the European banking industry and its effects on the price of the common stock of banks listed on European stock exchanges. We estimate the overall effect of progress by comparing the changes in the stock price volatility of listed banks over the period from January 1990 to December 2005. Using univariate and bivariate GARCH models, we document that the introduction of the Euro and the enlargement of the European Union in May 2004 have contributed to the integration process of the banking industry in Europe. We also find evidence of negative volatility spillovers among bank stock returns for different groups of countries that have been involved in various recent stages of the European economic and political integration.     

Economic integration and the choice of commodity tax base with endogenous market structures

This paper analyzes the choice of commodity tax base when countries set their taxes noncooperatively in a two-country symmetric reciprocal dumping model of intraindustry trade with free entry and trade costs. We show that the consumption base (destination principle) dominates the production base (origin principle) when trade costs are high or demand is linear. For lower levels of trade costs and nonlinear demand, the welfare ranking of the two tax bases is ambiguous. Hence, there is no clear preference for a tax principle with an ongoing movement toward closer economic integration.     

Are Multinational Corporate Tax Rules as Important as Tax Rates?

Previous research has documented the influence of statutory tax rates on international firms' effective tax rates, or ETRs. We add to this body of research by examining common factors of the income tax base, which affects ETRs. Specifically, this study examines the determinants of effective tax rates for publicly traded companies based in European Union (EU) countries. The time period examined is after 2004, when all EU firms were required to use standardized accounting principles under International Financial Reporting Standards (IFRS). We find that, across EU countries, such factors are relatively consistent with factors found in studies of U.S. companies' effective tax rates, which include inventory, leverage, depreciation tax shield, and R&D intensity. We also find that the presence of country book-tax conformity rules increases effective rates. Importantly, our finding that such tax base (or rule) effects are at least as important as rate effects adds to the international debate about uneven tax structures around the globe.     

Do government preferences matter for tax competition?

This paper explores how government preferences affect capital tax decisions of a country. We develop a model in which governments, differentiating in their preferences for economic development and income equality, compete for mobile capital over corporation taxes. The key prediction of the model, borne out in data from OECD countries over the years 1990–2012, is that an increase in government preferences for pursuing economic development relative to income equality makes countries’ horizontal tax reactions stronger. Unlike the existing studies, our result contributes to the tax competition literature by highlighting the importance of government preferences in determining the extent of tax competition among countries and so offering a novel explanation for the widely observed heterogeneous tax policies across countries.     

Decline of Controlled Foreign Company Rules and Rise of Intellectual Property Boxes: How the European Court of Justice Affects Tax Competition and Economic Distortions in Europe

The European Court of Justice (ECJ) has become an influential player in the field of direct taxation in the European Union (EU) in the past 20 years. However, it is unclear whether or not the ECJ's decisions and the corresponding reactions by the member states actually contribute to tax neutrality in economic terms and, therefore, to the achievement of the internal market. In 2006, the ECJ limited the applicability of specific tax rules in the EU that are intended to prohibit the excessive use of low‐tax countries by multinationals. Our counterfactual analysis shows that the court's restriction of so‐called controlled foreign company rules and the related second‐round reactions by some member states – i.e. the introduction of low‐tax regimes for income from acquired intellectual properties (IP boxes for acquired IP) – cast doubt on the seemingly positive effects the ECJ has on reducing tax distortions. In addition, we demonstrate that the restricted applicability of IP boxes as endorsed by the OECD and the European Commission would strengthen tax neutrality in Europe.

欧盟税收管辖权的现状与趋势

欧盟有关税收问题的规定,约束了成员国的税收立法内容,并且已经超越成员国的独立税收管辖权,导致成员国税收管辖权部分转移,出现超越国家的税收管辖权现象。欧盟法律制度的主要目标之一就是消除统一市场的人为和制度障碍,促进共同市场内部的商品、劳动力、资本和服务流动。欧盟在处理与成员国之间的税收管辖权问题上已经取得了有益的进展,但是,税收管辖权由国家向国际组织行使的转变仍然任重道远。     

Tax Principles,Product Differentiation and the Nature of Competition

We analyze the choice between the origin and destination principles of taxation when there is product differentiation and Bertrand competition. If taxes are redistributed to consumers and demand is linear the origin principle dominates the destination principle whatever the degree of product differentiation and extent of economic integration. With nonlinear demand the origin principle dominates if there is sufficient economic integration. When the social value assigned to tax revenue is higher than the private value, the destination principle dominates for intermediate values of product differentiation and economic integration. The same results are also shown to hold with Cournot competition. JEL Code: F12, H20     

IAS/IFRS in Belgium: Quantitative analysis of the impact on the tax burden of companies

The adoption of International Accounting Standards and the International Financial Reporting Standards (IAS/IFRS) in the European Union is part of the European Commission's global tax harmonisation policy whose aim is to establish a common (consolidated) corporate tax base. The paper shows that the impact of an IAS/IFRS-based tax accounting on the effective tax burden of Belgian companies is large and not uniform across sectors. Some sectors, like construction and automotive vehicles, experience much larger increases in effective tax burdens than others. Globally the impact is relatively important. The analysis is conducted using the European Tax Analyzer (ETA), a multi-period forward looking program. In a European context, an IAS/IFRS-based tax accounting will increase the effective corporate tax burdens in all selected countries. However, it will most probably maintain the current tax competitive positions of EU countries. The expected broadening of the tax base could constitute an opportunity to reduce the corporate income tax rate without changing the overall effective burden.     

Value-added taxation and consumption

One of the main rationales for taxing consumption rather than income is that it is believed that consumption taxes discourage consumption, encourage savings, and thus generate higher economic growth. However, empirical evidence on the actual effectiveness of consumption taxes in stimulating savings is very limited. In this paper, we estimate the impact of a broad-based consumption tax, the value-added tax (VAT), on the aggregate consumption of fifteen European Union countries over the period 1961–2005. Our empirical results indicate, across a variety of estimation methods and specifications, that a one percentage point increase in the VAT rate leads to roughly a one percent reduction in the level of aggregate consumption in the short run and to a somewhat larger reduction in the long run.     

Prospects for Co-ordination of Corporate Taxation and the Taxation of Interest Income in the EU

This paper evaluates the recent proposals for a co-ordinated capital tax policy in the European Union, focusing on an EU-wide minimum withholding tax on interest income and alternative ways to increase the effective tax rate on corporate profits. The analysis draws on current theoretical and empirical research and views the recent capital tax reforms undertaken by individual member countries as rational adjustments to changing conditions in capital markets. Special emphasis is placed on the constraints for EU tax policy imposed by the possibility of shifting capital income to third countries. The paper concludes that some aggregate efficiency gains can be expected from the EU co-ordination proposals, but additional tax collections will be limited largely to the group of small savers while highly mobile large-scale investors are likely to avoid the EU tax.     

Evolution of international stock and bond market integration: Influence of the European Monetary Union

This paper examines the dynamic relationship between daily stock and government bond returns of selected countries over the past decade to infer the state and progress of inter-financial market integration. We proceed to empirically investigate the influence of the European Monetary Union (EMU) on time variations in inter-stock–bond market integration/segmentation dynamics using a two-step procedure: First, we document the downward trends in time-varying conditional correlations between stock and bond market returns in European countries, Japan and the US. Second, we investigate the causality and determinants of this interdependent relationship, in particular, whether the various macroeconomic convergence criteria associated with the EMU have played a significant role. We find that real economic integration and the reduction in currency risk have generally had the desired effect on financial integration but monetary policy integration may have created uncertain investor sentiments on the economic future of the EMU, thereby stimulating a flight to quality phenomenon.     

Opting for Opting‐In? An Evaluation of the European Commission's Proposals for Reforming VAT on Financial Services*

This paper provides a legal and economic analysis of the European Commission's recent proposals for reforming the application of VAT to financial services, with particular focus on their ‘third pillar’, under which firms would be allowed to opt in to taxation on exempt insurance and financial services. From a legal perspective, we show that the proposals’‘first and second pillars’ would give rise to considerable interpretative and qualification problems, resulting in as much complexity and legal uncertainty as the current regime. Equally, an option to tax could potentially follow significantly different legal designs, which would give rise to discrepancies in the application of the option amongst Member States of the European Union (EU). On the economic side, we show that quite generally, when firms cannot coordinate their behaviour, they have an individual incentive to opt in on business‐to‐business (B2B) transactions, but not on business‐to‐consumer (B2C) transactions. We also show that opting‐in eliminates the cost disadvantage that EU financial services firms face in competing with foreign firms for B2B sales. But these results do not hold if firms can coordinate their behaviour. An estimate of the upper bound on the amount of tax revenue that might be lost from allowing opting‐in is provided for a number of EU countries.     

The European Union Endorsement Process for International Financial Reporting Standards: A Telos-Based Analysis

The paper discusses the process for the endorsement of an IFRS in the European Union with regard to its compliance with teleological principles and with regard to the true and fair view. It begins with an exposition of the teleological principle under Roman law and its relationship to the true and fair view override, as known in the UK and in the EU. We then discuss firstly the telos-based criteria against which a new Standard is appraised during the endorsement process, and secondly the application of the true and fair view principle to the issue of which criteria an EU-endorsed IFRS should be appraised against as regards its application, using IFRS 3 as a specific illustration. The teleological principle is a crucial element in our conclusions. We show that this principle can be used, and in the EU is being used, to bypass democratic processes. The issues raised by this paper concern the operation of regulations designed to be, at least theoretically, context-neutral, within a specific legal and operational framework, that is, the European Union. But similar issues are likely to require consideration in other geographical areas, outside the European context.     

Taxes in an e-commerce generation

Rapid growth in e-commerce has altered the ability of jurisdictions to enforce commodity taxes on a destination basis. This results in different effective tax rates depending on the way in which goods and services are purchased and the characteristics of both the products and the sellers. We discuss the arguments for the destination principle as the appropriate place-of-taxation rule for consumption taxation of cross-border trade. We analyze various recent reforms to the value-added tax in the European Union in response to e-commerce. We then examine various policy options in the USA—maintaining the status quo, changing nexus rules, states adopting information reporting, and national reforms that require firms to remit taxes regardless of physical presence—and relate them to the recent European reforms. We conclude based on our analysis and the recent European Union experience that reforms at the national level appear to be the important next step to enforcing commodity taxes at destination in the USA.     

Destination taxation and evasion: Evidence from U.S. inter-state commodity flows

Tax evasion has been an important issue in the accounting literature for several decades, but the focus has been on corporate income taxes. We develop a new way to examine tax evasion that focuses on corporate transactions, rather than corporate profits. Specifically, we examine how commodity flows respond to destination sales taxes, allowing for tax evasion as a function of distance between trade partners. After accounting for transportation costs, we find that the effect of taxes decreases as distance increases. This is consistent with the notion that longer distances between trade partners hinder government oversight and increase the likelihood of successful tax evasion. Our results are robust with respect to outliers, strategic neighbor effects, information sharing agreements and other re-specifications. These results are important to policymakers because they evidence the difficulty of enforcing destination taxation in open economies such as U.S. states and the European Union.     

Incentives and Information Exchange in International Taxation

The exchange of taxpayer-specific information between national tax authorities has recently emerged as a key and controversial topic in international tax policy discussions, most notably with the OECD's harmful tax practices project and the EU's savings tax initiative. This paper analyzes the effects of information exchange and withholding taxes, recognizing that countries which agree to exchange information do not forfeit the ability to levy withholding taxes, and also focusing in particular on the effects of innovative revenue-sharing arrangements. Amongst the findings are that: (i) the transfer of withholding tax receipts to the residence country, as planned in the European Union, has no effect on equilibrium tax rates, but acts purely as a lump-sum transfer; (ii) in contrast, allocating some of the revenue from information exchange to the source country—counter to usual practice (though no less so than the EU agreement)—would have adverse strategic effects on total revenue; (iii) nevertheless, any withholding tax regime is Pareto dominated by information exchange combined with appropriate revenue sharing; and, in particular, (iv) sharing of the additional revenues raised from information provided, while efficiency-reducing, could be in the interests of large countries as a means of persuading small countries to provide that information voluntarily.

Corporate Tax Consolidation and Enhanced Cooperation in the European Union*

We assess the economic impact of introducing consolidation with formula apportionment in the European Union and consider alternative enhanced cooperation agreements. We find that the consolidation is likely to yield a small aggregate welfare gain in Europe. However, not all countries benefit. A coalition of winning countries reduces the welfare gain and may induce a process of adverse selection which destroys the possibility of cooperation. We find that a coalition of similar countries (in terms of the size of their multinational sector) is more feasible in achieving agreement and is actually preferred by those countries over a Europe‐wide reform.
