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.

Preferential tax regimes with asymmetric countries

Current policy initiatives taken by the EU and the OECD aim at abolishing preferential corporate tax regimes. This note extends Keen's (2001) analysis of symmetric capital tax competition under preferential (or discriminatory) and non-discriminatory tax regimes to allow for countries of different size. Even though size asymmetries imply a redistribution of tax revenue from the larger to the smaller country, a non-discrimination policy is found to have similar effects as in the symmetric model: it lowers the average rate of capital taxation and thus makes tax competition more aggressive in both the large and the small country

Company tax coordination cum tax rate competition in the European Union

This paper reviews the recent theoretical literature that analyses the European Union's policy to eliminate preferential corporate tax regimes and the proposal to introduce a consolidated EU tax base with formula apportionment for the taxation of multinational firms. Since neither proposal includes a harmonisation of corporate tax rates, a core issue is how tax competition between member states will be affected by these partial coordination measures. The conclusions from our review are supportive of the EU's ban on preferential tax regimes, but the economic incentive effects of a switch to formula apportionment are found to be ambiguous

Competition for Firms in an Oligopolistic Industry: Do Firms or Countries Have to Pay?

We set up a model of generalised oligopoly where two countries of different size compete for an exogenous, but variable, number of identical firms. The model combines a desire by national governments to attract internationally mobile firms with the existence of location rents that arise even in a symmetric equilibrium where firms are dispersed. As economic integration proceeds, equilibrium taxes decline, switching from positive to negative levels, and then rise as trade costs fall even further. A range of trade costs is identified where economic integration raises the welfare of the small country, but lowers welfare in the large country

Unionisation triggers tax incentives to attract foreign direct investment

This paper analyses tax competition between a unionised and a non-unionised country for the location of an outside firm. We show that unionisation offers an extra incentive for the government to attract a foreign competitor to a concentrated domestic market, in order to affect the behaviour of the domestic union. This results in the unionised country's government offering a tax discount (or a subsidy premium) to the outside firm in excess of what is needed to compensate the investor for the higher union wage. In equilibrium, therefore, the unionised country can attract the outside firm even if it has other location disadvantages, such as a smaller home market

Merger Policy and Tax Competition

In many situations governments have sector-specific tax and regulation policies at their disposal to influence the market outcome after a national or an international merger has taken place. In this paper we study the implications for merger policy when countries non-cooperatively deploy production-based taxes. We find that whether national or international mergers are more likely to be enacted in the presence of nationally optimal tax policies depends crucially on the ownership structure of firms. When all firms are owned domestically in the pre-merger situation, non-cooperative tax policies are more efficient in the national merger case and smaller synergy effects are needed for this type of merger to be proposed and cleared. These results are reversed when there is a high degree of foreign firm ownership prior to the merger

Cross-border loss offset can fuel tax competition

Following recent court rulings, cross-border loss compensation for multinational firms will likely be introduced, at least in Europe. This paper analyzes the effects of introducing a coordinated cross-border tax relief in a setting where multinational firms choose the size of a risky investment and host countries endogenously choose tax rates. We show that coordinated cross-border loss compensation is likely to intensify tax competition when, following current international practice, the parent firm's home country bases the tax rebate for a loss-making subsidiary on its own tax rate. In equilibrium, tax revenue losses will then be even higher than is implied by the direct effect of the reform. In contrast, tax competition will be mitigated when the home country bases its loss relief on the tax rate in the subsidiary's host country

Market structure and the taxation of international trade

The paper compares non-cooperative commodity taxation under the destination and origin principles under a variety of different assumptions about market structure. We consider a model of international duopoly with either quantity or price competition of firms and either segmented or integrated markets, and a monopolistic competition model with mobile firms. In each setting the international spillovers of tax policy are isolated and evaluated at the Pareto efficient tax rate. The sign of the net spillover, and thus the direction that commodity tax competition will take, depends critically on whether lump-sum taxes are available or commodity taxes must be used to finance the government budget

Competition for firms in an oligopolistic industry : the impact of economic integration

We set up a model of generalised oligopoly where two countries of different size compete for an exogenous, but variable, number of identical firms. The model combines a desire by national governments to attract internationally mobile firms with the existence of location rents that arise even in a symmetric equilibrium where firms are dispersed. As economic integration proceeds, equilibrium taxes initially decline, but then rise again as trade costs fall even further. A range of trade costs is identified where economic integration raises the welfare of the small country, but lowers welfare in the large country

Reforming an Asymmetric Union: On the Virtues of Dual Tier Capital Taxation

The tax competition for mobile capital, in particular the reluctance of small countries to agree on measures of tax coordination, has ongoing political and economic fallouts within Europe. We analyse the effects of introducing a two tier structure of capital taxation, where the asymmetric member states of a union choose a common, federal tax rate in the first stage, and then non-cooperatively set local tax rates in the second stage. We show that this mechanism effectively reduces competition for mobile capital between the members of the union. Moreover, it distributes the gains across the heterogeneous states in a way that yields a strict Pareto improvement over a one tier system of purely local tax choices. Finally, we present simulation results, and show that a dual structure of capital taxation has advantages even when side payments are feasible
