The effects of labour unions on international capital tax competition

Abstract We analyze the impact of labour market rigidities on tax competition between two imperfectly integrated countries. Following a shift from a competitive to a unionized labour market in both countries, the capital tax can be adjusted upward in the country with the less rigid labour market, whereas the capital tax is always adjusted downward in the other country. Moreover, by reducing the labour cost differential between countries, trade liberalization gives rise to tax and welfare convergences. Finally, when a country adopts a flexible labour market, the unionized country may attract the majority of capital.     

Agglomeration and tax competition

Tax competition may be different in ‘new economic geography settings’ compared to standard tax competition models. If the mobile factor is completely agglomerated in one region, it earns an agglomeration rent which can be taxed. Closer integration first results in a ‘race to the top’ in taxes before leading to a ‘race to the bottom’. We reexamine these issues in a model that produces stable equilibria with partial agglomeration in addition to the core-periphery equilibria. A bell-shaped tax differential also arises in our model. Therefore, the ‘race to the top’ result generalises to a framework with partial agglomeration.     

EU regional policy and tax competition

The European Union (EU) provides coordination and financing of trans-European transport infrastructures, i.e. roads and railways, which link the EU member states and reduce the cost of transport and mobility. This raises the question of whether EU involvement in this area is justified by inefficiencies of national infrastructure policies. Moreover, an often expressed concern is that policies enhancing mobility may boost tax competition. We analyze these questions using a model where countries compete for the location of profitable firms. We show that a coordination of investment in transport cost reducing infrastructures within union countries enhances welfare and mitigates tax competition. In contrast, with regard to union-periphery infrastructure, the union has an interest in a coordinated reduction of investment expenditures. Here, the effects on tax competition are ambiguous. Our results provide a rationale for EU-level regional policy that supports the development of intra-union infrastructure.     

A journey from a corruption port to a tax haven

We sketch a model according to which tax havens attract corporate income generated in corrupted countries. We consider the choice of optimal bribes by corrupt officials and the share of the proceeds of corruption that will be concealed in tax havens. Our framework provides novel welfare implications of tax havens. First, tax havens’ services have a positive effect on welfare through encouraging investment by firms fearing expropriation and bribes in corrupt countries. Second, by supporting corruption and the concealment of officials’ bribes, tax havens discourage the provision of public goods and hence have also a negative effect on welfare. The net welfare effect depends on the specified preferences and parameters. One source of this ambiguity is that the presence of multinational firms in corrupted countries is positively associated with demanding tax havens’ operations. Using firm-level data, we provide new empirical results supporting this hypothesis.     

The effects of regional tax and subsidy coordination on foreign direct investment

This paper analyses the effects of a regionally coordinated profit tax or location subsidy 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 coordination can lead to two types of welfare gain. First, for investments that would take place in the union in the absence of coordination, a coordinated tax increase can transfer location rents from the firm to the union. Second, by internalising all of the union's benefits from foreign direct investment, a coordinated tax reduction can attract more welfare-enhancing investment than when member states act in isolation. Depending on which motive dominates, tax levels may thus rise or fall under regional coordination.     

On the welfare effects of competition for foreign direct investments

This paper investigates welfare effects of subsidy competition for the location of a multinational enterprise. One of the competing regions benefits more from the inward investment but, in the absence of incentives, the multinational's preferred location is the other, more advanced region. The paper shows that subsidies, by making the multinational switch location, may increase aggregate welfare. If the multinational exports in the absence of incentives, the welfare effects of subsidy competition may look very different. Allowing subsidies attracts the direct investment, which otherwise would not take place, in one of the two regions. Further, it intensifies competition in the market. The paper shows that the welfare increasing role of incentives may be amplified, but also that the competition effect, by hurting domestic firms, may cancel out any other positive role of incentives.     

Decentralization and international tax competition

This paper models tax competition between two countries that are divided into regions. In the first stage of the game, the strategy variable for each country is the division of a continuum of public goods between central and regional government provision. In the second stage, the central and regional governments choose their tax rates on capital. A country's decentralization level serves as a strategic tool through its influence on the mix of horizontal and vertical externalities that exists under tax competition. In contrast to standard tax competition models, decentralizing the provision of public goods may improve welfare.     

The impact of endogenous tax treaties on foreign direct investment: theory and evidence

Abstract .  This paper investigates the effect of tax treaties on bilateral stocks of outward FDI. For this purpose we employ a numerically solvable general equilibrium model of trade and multinational firms to study the impact of tax treaties on both welfare and outward FDI. The model indicates under which factor endowment configurations countries gain in welfare when implementing a tax treaty. This motivates an empirical specification of the endogenous selection into implementing new tax treaties. Using data of bilateral OECD outward FDI between 1985 and 2000, we find a significant negative impact of newly implemented tax treaties on outward FDI stocks.     

Congestion and tax competition in a parallel network

The purpose of this paper is to study the effects of tolling road use on a parallel road network where each link can be tolled by a different government. Using both theoretical and numerical models, the paper analyses the potential tax competition between countries that each maximise the surplus of local users plus tax revenues in controlling local and transit transport. Three types of tolling systems are considered: (i) toll discrimination between local traffic and transit, (ii) only uniform tolls on local and transit transport are acceptable, (iii) tolls on local users only. The results suggest that the welfare effects of introducing transit tolls are large, but that differentiation of tolls between local and transit transport as compared to uniform tolls does not yield large welfare differences. Also, the welfare effects of toll cooperation between countries are relatively small in comparison with the welfare gains of non-cooperative tolling of transit. The numerical model further illustrates the effects of different transit shares and explicitly considers the role of asymmetries between countries. Higher transit shares strongly raise the transit toll and slightly decrease local tolls. With asymmetric demands, the welfare gains of introducing differentiated tolling rise strongly for the country with lower local demand.     

Corporate tax competition: A meta-analysis

Do jurisdictions compete over corporate taxes? The extent of uncooperative strategic government interactions in corporate tax policy remains unclear, because the results reported in relevant econometric studies vary considerably. This paper applies meta-analysis and meta-regression methods to a novel dataset consisting of 604 observations on corporate tax competition reported in 33 primary studies. The results point to the presence of corporate tax competition effects, and there is no consistent evidence for publication selection bias. The analysis, however, reveals that several data and specification choices systematically affect the results reported in the literature: the choice of the weighting scheme applied in estimating the corporate tax function and details of the econometric estimation strategy are significant when it comes to explaining variation in reported results. Furthermore, we find that accounting for partisan politics and country size matters.     

Innovation and international trade in technology

The international market for technology is growing rapidly relative to world GDP. To study the international technology market, I present a model of innovation and international trade in which inventors auction their technology in both domestic and foreign markets. There is monopolistic competition in differentiated products. International trade in technology has number of significant economic effects. Technology trade improves the quality of innovation by increasing the pool of R&D experiments from which the best technology is chosen. Technology trade increases the efficiency of invention while at the same time lowering the total number of inventors relative to the equilibrium without technology trade. Technology trade increases the volume of trade in goods. Technology trade increases product variety at the market equilibrium. Technology trade increases national income in each country and increases total gains from trade.     

Intra-industry trade with multinational firms

Recent developments, including the analysis of firm-level adjustment to falling trade costs, have contributed to a revival of interest in intra-industry trade (IIT). Most empirical work still relies on the standard Grubel-Lloyd measure. This however refers only to international trade, disregarding income flows stimulated by repatriated profits of multinational firms. Given the overwhelming importance of the latter, this is a major shortcoming. This paper provides a guide to measurement and estimation of the determinants of bilateral IIT shares from the perspective of new trade theory with multinational firms. We develop an analytically solvable general equilibrium model to investigate the impact of investment costs, multinational activities and income flows from repatriated profits. We also discuss and quantify the bias of the Grubel-Lloyd index associated with repatriated profit flows of multinationals. Using bias-corrected versions of the Grubel-Lloyd index as the dependent variable, we demonstrate that the determinants motivated by our theoretical analysis offer important insights into variations in IIT shares.     

A welfare analysis of unilateral trade and FDI liberalization

This paper uses a heterogeneous‐firms model to examine the pro‐competitive channel through which FDI affects national welfare. The model shows that the country from which FDI originates experiences a welfare gain following liberalization. However, a counterintuitive finding is that the welfare of the host country deteriorates. This is explained by the production relocation process that leads to an increase in the mass of domestic firms in the source country and a decrease in the host country. The model also confirms that unilateral trade liberalization brings a similar result even in the presence of bilateral FDI flows.     

The demand for tax haven operations

What types of firms establish tax haven operations, and what purposes do these operations serve? Analysis of affiliate-level data for American firms indicates that larger, more international firms, and those with extensive intrafirm trade and high R and D intensities, are the most likely to use tax havens. Tax haven operations facilitate tax avoidance both by permitting firms to allocate taxable income away from high-tax jurisdictions and by reducing the burden of home country taxation of foreign income. The evidence suggests that the primary use of affiliates in larger tax haven countries is to reallocate taxable income, whereas the primary use of affiliates in smaller tax haven countries is to facilitate deferral of U.S. taxation of foreign income. Firms with sizeable foreign operations benefit the most from using tax havens, an effect that can be evaluated by using foreign economic growth rates as instruments for firm-level growth of foreign investment outside of tax havens. One percent greater sales and investment growth in nearby non-haven countries is associated with a 1.5 to 2% greater likelihood of establishing a tax haven operation.     

On the welfare effects of trade and investment liberalization

Using a three-factor knowledge- and physical capital model of trade and multinational activity, we consider a set of policy experiments to assess the welfare effects of trade and investment liberalization in general equilibrium. Specifically, we address the question of whether and under which circumstances a single versus a combined trade/investment liberalization strategy or a unilateral versus a bilateral policy change is preferable from a single country's and the world's point of view. The focus of this paper is to look at three relevant questions. First, when is investment liberalization beneficial and when is it harmful for a single economy or the whole world? Second, is pure investment liberalization a welfare maximizing strategy? Third, when is either kind of liberalization (trade, investment, or both) welfare improving and when neither of them?     

Greasing the wheels of international commerce: how services facilitate firms’ international sourcing

Abstract We use plant‐level data to study the link between the local availability of services and the decision of manufacturing firms to source materials from abroad. We develop a model to generate predictions about how the intensity of international sourcing of materials depends on the availability of services and firm characteristics. These predictions are supported by the data. Greater availability of services across regions, industries, and time increases firms’ foreign sourcing of materials relative to sales. The impact of services differs by firm type. National firms’ sourcing responds to changes in regional service conditions, whereas multinationals tend to be less affected.     

Company taxation and tax spillovers: Separate accounting versus formula apportionment

It is observed in the real world that taxes matter for location decisions and that multinationals shift profits by transfer pricing. The US and Canada use so-called formula apportionment (FA) to tax corporate income, and the EU is debating a switch from separate accounting (SA) to FA. This paper develops a theoretical model that compares basic properties of FA to SA. The focal point of the analysis is how changes in tax rates affect capital formation, input choice, and transfer pricing, as well as on spillovers on tax revenue in other countries. The analysis shows that a move from SA to FA will not eliminate such spillovers and will, in cases identified in the paper, actually aggravate them.     

Neckties in the tropics: a model of international trade and cultural diversity

Abstract .  Some cultural goods are consumed socially and are characterized by the same consumption network externalities as languages. Also, producers of new cultural goods in any one country draw on the stock of ideas generated by previous cultural production in all countries. For such goods, costless trade and communication tend to lead to the dominance of one cultural style, increasing utility in the short run but reducing quality and welfare in the long run. Increasing protection while keeping communication costs low may stimulate production of cultural goods that are 'compatible' with the dominant style, adding little to the stock of usable ideas.     

Competition in taxes and performance requirements for foreign direct investment

Tax incentives offered to attract firms engaged in foreign direct investment are often tied to performance requirements such as domestic content restrictions or adherence to environmental standards. The tax competition literature has repeatedly shown that competition between municipalities for mobile firms tends to drive taxes to low levels. One would expect a comparable result for burdensome performance requirements. Despite this, the evidence suggests that while taxes have indeed been driven down, performance requirements are as popular as ever. We explain this seeming conundrum by showing that in the presence of spillovers, binding performance requirements can act as a coordination device for firms. In equilibrium, municipalities choose performance requirements, which maximize joint surplus from investment. Competition between municipalities then transfers this surplus to firms via tax subsidies.     

Profit taxation and the mode of foreign market entry

Abstract This paper studies the role of profit taxation for an international firm's decision upon how to penetrate a foreign market – through exports or through foreign direct investment (FDI) and local supply. We show that with harmonized taxes the international firm may choose FDI even though this has welfare costs from a global point of view. With tax competition, the host country can enforce exporting instead of FDI. This leads to a Nash equilibrium associated with higher world welfare than harmonized taxes. Thus, because of the effect on entry mode, tax competition provides heretofore unexplored benefits as compared to tax harmonization.
