On the theory of interregional tax incidence

The state of factor income distribution prevailing in a local jurisdiction may be greatly influenced by the change in tax policies carried out by some other local jurisdictions through the market mechanism. The theory of interregional tax incidence is concerned with the problem of interactive distributional effects among local jurisdictions when each local government executes independently tax policies. This paper develops a new method of conducting a comparative static analysis on the current issue by making use of a general equilibrium model of interregional tax incidence characterized by the assumption that labor is perfectly immobile between different jurisdictions.     

Is it tax competition or tax exporting?

This paper extends the basic tax-competition model to a framework in which jurisdictions have market power over the price of the output produced within their borders. If firms within the jurisdiction are competitive, the jurisdiction can play the role of monopoly-rent collector by using taxes to restrict the level of output. It is shown that the basic tax competition model can be thought of as a special case of this more general framework. In this framework, the opportunity to export the tax burden can partially or fully offset the well-known effects identified by the tax competition model.     

A note on tax competition in the presence of agglomeration economies

This paper analyzes tax competition in the presence of agglomeration effects. The obtained results are then compared to the results of the traditional model, without agglomeration effects. As is well known, the presence of a fiscal externality affects the provision of the public good in the standard competitive model of tax competition. In the model with agglomeration effects, in addition to this externality, a new effect shows up. This effect reflects heightened government concern about capital flight, which depresses firm productivity by limiting external economies of scale. As a result, capital tax rates end up being lower than in the case where agglomeration effects are not present, worsening the underprovision of the public good. This conclusion holds in both the competitive and strategic versions of the model.     

A theory of multihoming in rideshare competition

We examine competition among ridesharing platforms, where firms compete on both price and the wait time induced with idled drivers. We show that when consumers are the only agents who multihome, idleness is lower in duopoly than when consumers face a monopoly ridesharing platform. When drivers and consumers multihome, idleness further falls to zero as it involves costs for each platform that are appropriated, in part, by their rival. Interestingly, socially superior outcomes may involve monopoly or competition under various multihoming regimes, depending on the density of the city, and the relative costs of idleness versus consumer disutility of waiting.     

Redistribution and regional development under tax competition

This paper considers how capital tax competition affects transfer and development policies in the presence of regional income disparity. In each country, development policies determine the number of rich (poor) regions that (do not) engage in production activities, while transfer policies redistribute income between rich and poor regions. The mix of transfer and development policies is inefficient under tax competition: conditional on the equilibrium tax rate, too much revenue is spent on development policies and too little on transfer policies. This analysis of the expenditure mix implies that development policies are used as a means of regional redistribution even if transfer policies are efficient instruments for this purpose. Moreover, it is shown that the overall level of public expenditure may be too high because of the possibility of over-development.     

Even small trade costs restore efficiency in tax competition

We introduce transport cost of trade in products into the classical Zodrow and Mieszkowski (1986) model of capital tax competition. It turns out that even small levels of transport cost lead to a complete breakdown of the seminal result, the underprovision of public goods. Instead, there is a symmetric equilibrium with efficient public goods provision in all jurisdictions.     

A neoclassical model of interregional economic growth

Interregional economic growth is characterized by free trade, capital movements and labour migration. An interregional equilibrium and a steady state are likely to exist, and if a disturbance occurs, there might be a tendency back to equilibrium. Output and income grow at the same rate in all regions, although the regions differ in technology, propensity to save and natural growth of labour; these factors also determine the speed of expansion. Yet if the natural growth of labour is too fast (too slow), then capital and labour tend to a single region.     

Interregional tax competition and intraregional political competition: The optimal provision of public goods under representative democracy

This paper explores the implications of the interaction between interregional tax competition and intraregional political competition for the optimal provision of public goods under representative democracy à la Osborne and Slivinski, 1996, Besley and Coate, 1997. As an extension of Hoyt’s (1991) finding that intensified tax competition is always harmful and aggravates the extent to which public goods are undersupplied in a region, we show that intensified tax competition can be beneficial if political as well as tax competition is considered. In particular, we identify plausible conditions under which (i) there is an optimal intensity of tax competition such that the interaction between interregional tax competition and intraregional political competition will result in the optimal provision of public goods and (ii) intensified tax competition will be beneficial if and only if the degree of tax competition is less than this optimal intensity.

Can partial fiscal coordination be welfare worsening?: A model of tax competition

Most work on tax competition argues that mobile factors tend to be undertaxed except if there is coordination of tax policies. Full coordination is not however always feasible, and as a consequence some measures of partial coordination have been proposed such as minimal withholding taxes on interest income. We show that partial coordination can be in some instances welfare worsening and that then no coordination is to be preferred.     

A note on interregional versus intraregional inequality

This paper addresses the decomposition of inequality in an interrogional and intraregional component. In addition to cardinal data (income), attention is paid to binary data (e.g., unemployment). Some specific features of binary data which are relevant in the context of inequality analyses are studied. The decomposition approach is illustrated for Dutch provincial data.     

Income tax competition at the State and Local Level in Switzerland

Tax competition is supposed to lead to inefficiencies in the provision of public goods and difficulties for decentralized redistribution. A necessary condition for these effects to occur is that residence and location decisions are determined by fiscal considerations. In this paper, the impact of personal income taxes and transfer payments on residence decisions of taxpayers is analyzed using cross sectional data on the distribution of different groups of taxpayers in different income groups among the 26 Swiss cantons and the 137 largest Swiss cities. We find that tax competition with respect to personal income taxes is relatively strong in Switzerland.     

Investment in public infrastructure with spillovers and tax competition between contiguous regions

Two contiguous regions compete to attract a population of heterogeneous firms. They choose infrastructure levels in a first stage and compete in taxes in a second stage. We study the properties of Subgame Perfect Nash equilibria in this stage game depending on the extent to which the benefits of infrastructure spill over from one region to the other. First, we show that the presence of inter-regional spillovers allows jurisdictions to control for the intensity of tax competition and therefore affects the optimal levels of infrastructure selected at equilibrium. Second, by comparing the non-cooperative and cooperative outcomes, we show that the extent to which regions overinvest in infrastructures negatively depends on the intensity of the spillovers.

Double Bertrand tax competition: a fiscal game with governments acting as middlemen

In a common market with costless mobility of all factors regional governments can attract mobile firms by granting subsidies which they must finance out of wage taxes on mobile labour. Firms locate where subsidies are highest and workers settle where taxes are lowest, forcing government ‘in the splits’ (double Bertrand-type tax competition). Initially, there is unemployment in the economy. Regional governments then behave like middlemen in the labour market, and the fiscal game takes the form of competition among strategic intermediaries. Results from the theory of intermediation are applied to this framework. It is shown that government size may increase rather than decline in a fiscal competition, that industrial clustering may emerge from tax competition, and that tax competition may alleviate the unemployment problem.     

Lobbying and tax competition in an oligopolistic industry: a reverse home-market effect

This paper studies tax competition between two asymmetrical countries for an oligopolistic industry with many firms. Each government sets its tax rate strategically to maximize the weighted sum of residents’ welfare and political contributions by owners of firms. It is shown that if the governments care deeply about contributions and trade costs are low, the small country attracts a more than proportionate share of firms by setting a lower tax rate. The well-known home-market effect, which states that countries with a larger market attract a more-than-proportionate share of firms, may be reversed as a result of tax competition by politically interested governments.     

Local business taxation and competition for capital: the choice of the tax rate

A theoretical model describes the local choice of the tax rate on capital income. It establishes preferences and various fiscal conditions — including the tax rates of competing jurisdictions — as determinants of the tax rate. The empirical implications are tested using a large panel of jurisdictions in Germany, which have discretion in setting the local rate of the business tax. Tax competition is identified by means of instrumental variables techniques. Despite significant competition effects between local neighbors, where tax rates are strategic complements, jurisdictions are found to have some leeway in using the tax rate as an instrument of their policy. In particular, large jurisdictions set higher tax rates in interjurisdictional competition.
