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.     

Tax enforcement,tax compliance and tax morale in transition economies: A theoretical model

The focus of this paper is the analysis of the relationship between tax enforcement, tax compliance and tax morale within countries characterised by rapid introduction of market institutions and slow evolution of political regimes, such as transition economies. The paper investigates a coordination game in which the government is ex-ante committed to tax enforcement and can observe the proportion of tax-compliant agents in the economy. In turn, two groups of agents (third-party reporting and self-reported income) are keen to evade taxes unlawfully but have limited information on how many others evade taxes; their tax morale is therefore an endogenous function of agents' perception on tax compliance. The model predicts that the lower the quality of political institutions and the weaker tax morale, the less tax compliance can be achieved. The third-party reporting group will also be bearing higher tax burden than the self-reported income group. The model entails that having political institutions of good quality is not a sufficient condition to conduce to tax enforcement or tax compliance. Due to the endogenous role of tax morale, the government could be pushed ex-post towards poor or no tax enforcement. If good political institutions are not accompanied by good information about the enforcement of tax collection, there is scope for co-existence of poor tax enforcement, low tax compliance and weak tax morale. As such, this model well describes the tax evasion behaviour observed since the outset of transition from planned to market economy.     

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.     

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.     

Endogenous leadership and sustainability of enhanced cooperation in a repeated interactions model of tax competition: Endogenous leadership in tax competition

In this study, the endogenous timing of moves is analyzed in an infinitely repeated game setting of capital tax competition between a subgroup (a tax union) of countries agreeing on partial tax harmonization and outside countries. It is shown that in a subgame perfect equilibrium of the infinitely repeated tax competition game, they simultaneously set capital taxes in every stage game when a tax union comprises similar countries with respect to productivity, whereas they may set capital taxes sequentially in every stage game when a tax union comprises dissimilar countries. This finding is significantly different from Ogawa (2013), although we also assume that capital is owned by the country's residents, as in Ogawa's model. This is because a disadvantaged member country of the tax union would suffer from larger losses when a tax union comprising dissimilar countries, and thus the tax union will choose the strategy of moving Late for the sake of sustaining tax harmonization to avoid such losses.     

Lobbying,political competition and the welfare effect of campaign contribution tax

This paper develops a probabilistic voting model in which a single lobby group commits campaign contributions to parties, contingent on the policy position the party adopts. Parties may have different propensities for diverting campaign funds towards rents. We show that a party that skims more from contributions mobilises fewer uninformed voters but places more value on receiving greater contributions. Further, the contributions and vote share of the party increases with the distance between the lobby's preferred policy and the median voter's ideal policy. Finally, we show that the equilibrium policy is between the median voter's ideal point and the lobby's preferred policy. Such an equilibrium policy does not maximise the aggregate social welfare due to the distortionary nature of lobbying. However, when an appropriate contribution tax is introduced to limit this distortion, social welfare will be maximised.     

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.     

Economic versus political symmetry and the welfare concern with market integration and tax competition

The paper studies the implications of increased capital market integration and the associated increased tax competition for world welfare. We consider a population with heterogeneous endowments of capital in a model of redistributive politics. We show that if countries have the same average capital endowments but differ with respect to the endowments of their decisive majority, autarky may be socially preferred to integration under any aversion to inequality. We then reverse the conclusion by assuming that the decisive majority has the same endowment but countries differ in their average capital endowments. In proving these results we show that integration may decrease world output and increase the utility of the poorest members of the economy.     

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.     

Strategic delegation in asymmetric tax competition

This study examines asymmetric tax competition under representative democracy systems. The findings show that the degree of asymmetry between countries affects the result of elections in each country, where the citizens select a policy‐maker to set a tax rate for the country. In particular, under certain conditions, a decisive voter in the election can select a citizen whose share of the country's capital is higher than the decisive voter's own share.     

Identifying peers in international tax competition

Multinational companies (MNCs) have historically used corporate subsidiaries to isolate income earned in lower-taxed jurisdictions from tax in a higher-rate home country. This planning technique has been long accepted as a strategy to lower the MNC’s effective tax rate and maintain shareholder value. A recently study, however, demonstrates that this is an inefficient, and possibly inappropriate, strategy. This article conducts a comprehensive empirical benchmarking analysis by applying cluster analysis to empirically identify peer groups of MNCs operating in the pharmaceutical industry. We find that most firms consistently fall into the same cluster, providing evidence that income shifting can be benchmarked by industry sector. We also find special cases where firms should be excluded from the benchmark.     

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 principles and tax harmonization under imperfect competition: A cautionary example

This paper shows that under imperfect competition, the welfare effects of indirect tax harmonization may depend crucially on whether taxes are levied by the destination or the origin principle. In a standard model of imperfect competition, while harmonization always makes at least one country better off, and may be Pareto-improving, when taxes are levied under the destination principle (which currently applies in the European Union), harmonization of origin-based taxes (as recently proposed by the European Commission) is certain to be Pareto-worsening when the preferences in the two countries are identical, and is likely to be so even when they differ.     

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.     

A spatial tax harmonization model

Policies to harmonize value-added tax rates are controversial in the European Union. This paper formulates a multi-country model over a one-dimensional space as a non-cooperative Nash game, in which each country aims at maximizing its tax revenue, subject to the constraint that its tax rate lies within a given common band. Then we examine the effects of changes in the common band on tax rates, tax revenues and the number of cross-border shoppers at Nash equilibrium. We also analyze the effects of geographical variation in country size and location.
