A bargaining model of tax competition

This paper develops a model in which competing governments offer financial incentives to induce individual firms to locate within their jurisdictions. Equilibrium is described under three specifications of the supplementary taxes. There is no misallocation of capital under two of these specifications, and there might or might not be capital misallocation under the third. This result contrasts strongly with that of the standard tax competition model, which does not allow governments to treat firms individually. That model finds that competition among governments almost always leads to capital misallocation.     

The political economy of capital market integration and tax competition

This paper investigates the effect of capital market integration (CMI) on capital taxes in a political economy framework in which policy is influenced by lobbying of interest groups. CMI increases the efficiency cost of the capital tax, which introduces incentives to reduce the tax rate, but also reduces lobbying by owners of capitalists, which introduces countering incentives to increase the tax rate. CMI can therefore result in a higher capital tax rate. When the market share of each country is small, CMI may increase government supply of public goods and enhance efficiency, which implies that, in the presence of policy endogeneity through lobbying, decentralized policymaking can be more efficient than centralized policymaking.     

Endogenizing leadership in tax competition

In this paper we extend the standard approach of horizontal tax competition by endogenizing the timing of decisions made by the competing jurisdictions. Following the literature on the endogenous timing in duopoly games, we consider a pre-play stage, where jurisdictions commit themselves to move early or late, i.e. to fix their tax rate at a first or second stage. We highlight that at least one jurisdiction experiments a second-mover advantage. We show that the Subgame Perfect Equilibria (SPEs) correspond to the two Stackelberg situations yielding to a coordination problem. In order to solve this issue, we consider a quadratic specification of the production function, and we use two criteria of selection: Pareto-dominance and risk-dominance. We emphasize that at the risk-dominant equilibrium the less productive or smaller jurisdiction leads and hence loses the second-mover advantage. If asymmetry among jurisdictions is sufficient, Pareto-dominance reinforces risk-dominance in selecting the same SPE. Three results may be deduced from our analysis: (i) the downward pressure on tax rates is less severe than predicted; (ii) the smaller jurisdiction leads; (iii) the ‘big-country-higher-tax-rate’ rule does not always hold.     

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.     

Capital tax competition: bane or boon

This paper reviews potential advantages and disadvantages of capital tax competition. Tax competition may introduce, mitigate, or exacerbate inefficiencies in both the private sector and the public sector. In different models, tax competition may either limit or increase public expenditures and taxes on mobile factors, with differing welfare consequences. We also discuss the implications of tax competition for redistributive policies and for policies dealing with risk, and we identify some of the possible empirical implications of tax competition.     

Endogenous political competition and political accountability

We contribute to the debate over the effectiveness of elections in motivating incumbents to perform well. We show that with endogenous political competition the effectiveness of democracy in disciplining officials can be largely diminished.     

A tax programming model

This paper presents a new technique for analysing tax reform proposals. The technique is general in the sense that it allows the user to choose the targets he thinks are the most important. Using this technique the Israeli Income Tax Reform of 1975 is evaluated.     

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.     

Tax competition,tax coordination and tax harmonization: The effects of EMU

There is little doubt that the step towards a monetary union in Europe will increase both the distorionary effects of existing differences in national tax systems and the intensity of tax competition for internationally mobile commodity and factor tax bases. This paper discusses selected issues of commodity and capital tax coordination that are likely to be affected by monetary unification. Starting from the distortive present scheme of value-added taxation in Europe we first analyze the effects of a switch to a general origin-based VAT as a way to maintain national tax rate autonomy over this important tax base. While an origin-based VAT would neither distort trade flows — both within the EU and with third countries — nor investment decisions in the long-run, its short-run effects are likely to be severe in the absence of exchange rate flexibility. In the field of capital taxation the focus switches to the feasibility of regional harmonization measures when there is no cooperation with the rest of the world. We argue that in a monetary union the mobility costs of capital will be significantly lower within the EU as compared to outside investments. This provides an efficiency argument for minimum source taxes on both interest income and corporate profits even if cooperation with third countries is infeasible.     

Tax competition and the political economy of public employment: a model for Austria

In this work, we simulate the effects of the tax autonomy of the Austrian states on the levels of public employment in each state. We show that depending on the strength of the public sector lobby, tax autonomy would require a reduction of employment in the public sector of between 25 and 35% of the current level. We also show that tax autonomy increases welfare levels by 1–1.5%; that is, the positive change in the disposable income of the workers more than offsets the welfare loss resulting from the lower provision of public goods. Finally, we show that the reduction of public employment is superior in terms of welfare to an alternative scenario in which employment levels are held constant but the wage levels in the public sector are adjusted.     

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.     

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.     

An exercise in political economy of tax reform

If the tax rate is endogenously determined by majority voting, then a fully effective and costless reform resulting in full tax compliance may not be supported by a majority even when the evaders (or, avoiders) are only a minority.     

Search costs and corporate income tax competition

If a small cost applies for learning the corporate tax rules in different countries, this can completely eliminate tax competition. This modified version of the Diamond paradox and can also explain the empirically observed tax cuts cum base broadening.     

Fairness, errors and the power of competition

In this paper, we investigate the effects of competition on bargained outcomes. We show that the neglect of either fairness concerns or decision errors will prevent a satisfactory understanding of how competition affects bargaining. We conducted experiments which demonstrate that introducing a small amount of competition to a bilateral ultimatum game – by adding just one competitor – induces large behavioral changes among responders and proposers, causing large changes in accepted offers. Models that assume that all people are self-interested and fully rational do not adequately explain these changes. We show that a model which combines heterogeneous fairness concerns with decision errors correctly predicts the comparative static effects of changes in competition. Moreover, the combined model is remarkably good at predicting the entire distribution of offers in many different competitive situations.     

A general disequilibrium model of tax incidence

This paper applies a general disequilibrium approach to the tax incidence problem. Separate sections have examined the incedence of various taxes in an economy experiencing general excess demand and excess supply. The specific inclusion of these disequilibrium elements leads to some results markedly different from those obtained in an equilibrium model. The tax incidence is measured by the labor-capital ratio rather than by the familiar wage-rental ratio. The incidence of a partial factor tax can easily and definitely be shown to fall in a greater proportion on the taxed factor than on the untaxed one.     

A spatial model of corporate tax incidence

Using a unique, self-compiled data-set on international tax rates, we explore the link between taxes and manufacturing wages for a panel of 66 countries over 25 years. We find, controlling for other macroeconomic variables, that wages are significantly responsive to corporate taxation. Higher corporate tax rates depress wages. Using spatial modelling techniques, we also find that tax characteristics of neighbouring countries, whether geographic or economic, have a significant effect on domestic wages. We test for, and reject, spatial autocorrelation in our model using a modification of the Moran-I test statistic that accounts for country-specific fixed effects in a panel data setting. Our article fits in with the new economic geography literature as well as the urban economics literature which attempt to explain the spatial distribution of wages.     

Delegation and polarization of platforms in political competition

Summary. We consider a model of political competition among two ideological parties who are uncertain about the distribution of voters. The distinguishing feature of the model is that parties can delegate electoral decisions to candidates by nomination. It is shown that if the credible platform commitments of the candidates is feasible, then at least one of the parties nominates in equilibrium to a candidate who has an ideology that is more radical than the delegating party's ideology. In a variety of circumstances, this, in turn, yields a polarization of equilibrium policy choices of the candidates. It is thus argued formally here that strategic nomination of the candidates may well be one of the major reasons behind the well documented observation that the platforms associated with the political parties in two-party democracies are often surprisingly polarized.
