Corporate tax avoidance and cost of equity capital: international evidence

ABSTRACT

This study examines the association between firm’s tax avoidance activities and cost of equity capital across 17 countries. Consistent with the prior study based on the U.S. evidence, within strong investor protection countries, the extent of firm’s tax avoidance is negatively associated with its cost of equity capital. This result indicates that strong investor protection induces investors to perceive firm’s tax avoidance activities as the results of efficient tax planning to reduce tax liabilities. To the contrary, we find that the extent of firm’s tax avoidance is positively associated with its cost of equity capital within weak investor protection countries. This result suggests that investors impose equity risk premium on firm’s tax avoidance activities in weak investor protection countries, where agency conflicts prevail more on firm’s tax avoidance activities. As the first international study on the association between firm’s tax avoidance activities and its cost of equity capital, this study contributes to the literature by suggesting that such an association may vary across countries depending on the strength of investor protection within each country of domicile.     

Optimal fiscal policy in a dynamic multicountry world with public services

The authors construct a dynamic one‐good multicountry growth model with productive government spending and perfect capital mobility to study fiscal interdependence among countries. In the case of a source‐based tax, it is found that there is no strategic interaction and that the equilibrium spending/tax mix coincides with the optimal one. In the case of a residence‐based tax system, however, there is strategic interaction across countries and, under noncooperation, countries tend to spend and tax over and above the optimal Pigouvian level.     

Royalty taxation under tax competition and profit shifting

Multinational corporations increasingly use royalty payments for intellectual property rights to shift profits globally. This not only threatens the tax base of countries worldwide but also affects the nature of tax competition. Against this background, our theoretical analysis suggests a surprising solution to the problem of curbing profit shifting without suffering major outflows of capital: a strictly positive withholding tax on royalty payments is both the Pareto-efficient solution under international coordination and the optimal unilateral response. If internal debt is sufficiently responsive, governments can even implement optimal targeting. Then, the royalty tax closes the profit-shifting channel, while all competition for mobile capital is relegated to internal-debt regulation. Our results question the ban on royalty taxes in double tax treaties and the EU Interest and Royalty Directive.     

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.     

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.     

Environmental capital flight and pollution tax

This paper analyzes the impacts of a production pollution tax on environmental capital flight and national product in a two-country static general equilibrium model with two-way foreign investment. It is assumed that the capital input in both countries is a composite good of domestic and imported capital. And pollution is assumed to originate in the production process. The productivity of capital in each country is negatively (or positively) related to the worldwide aggregate emissions.The analysis shows that when a domestic pollution tax is levied, domestic capital outflows increase and foreign capital inflows decrease for sufficiently high elasticities of substitution between labor (immobile input) and capital (mobile input) in both countries. Moreover, with negative transnational externalities, increases of a domestic pollution tax reduce domestic production and increase foreign production. The difficulty of substitution between immobile and mobile inputs hinders the optimal allocation of worldwide capital and national product. In this paper, the optimal pollution tax is based on global welfare maximization, not on global income maximization, taking into consideration the impact of income change on individual welfare. Therefore, an optimal pollution tax in the developing country should be lower for a given rate of pollution.

Implementing partial tax harmonization in an asymmetric tax competition game with repeated interaction

This paper investigates the conditions under which partial harmonization for capital taxation is sustained in a repeated interactions model of tax competition when there are three countries with heterogenous capital endowments. We show that regardless of the structure of the coalition (i.e., full or partial tax coordination), whether partial tax harmonization is sustainable or not crucially depends on the extent to which the capital endowment of the medium‐sized country is similar to that of the large or small country. The most noteworthy finding is that the closer the capital endowment of the median country is to the average one, the less likely the tax harmonization including the median country is to prevail and the more likely the partial tax harmonization excluding the median country is to prevail. We also show that partial tax harmonization makes the member countries of the tax union better off and non‐member countries worse off, which stands in sharpe contrast with previous studies, such as Konrad and Schjelderup (1999) and Bucovetsky (2009).     

Capital Mobility, Agglomeration and Corporate Tax Rates: Is the Race to the Bottom for Real?

Based on a data set for 19 OECD countries for the period 1981–2001,we estimate the impact of FDI on corporate tax rates, wherechanges in FDI are a measure for changes in capital mobility.So far the literature has been concerned with the related butrather different question as to the sensitivity of FDI to taxrates. Our article takes an opposite perspective and asks whatthe impact of capital mobility is on corporate tax rates. Indoing so, we explicitly take the role of agglomeration intoaccount. In theory, core countries can afford a higher tax ratecompared to peripheral countries. In our estimation strategy,we instrument capital mobility to deal with reverse causality.The main conclusion is that increased international capitalmobility, measured by FDI flows, implies a lower corporate taxrate. But we also find that agglomeration matters: core countrieshave a higher corporate tax rate than peripheral countries.If there is a race to the bottom, it seems that it is more realfor some countries than others.

Fiscal harmonization in the European Union with public inputs

Fiscal harmonization among the European Union member states is a goal involving major difficulties for its implementation. Each country faces a particular trade-off between fiscal revenues generated by taxation and the productive efficiency loss induced by their respective tax code. This paper provides a quantitative analysis of these trade-offs for a number of the European Union (EU-15) member states using a dynamic general equilibrium model with public inputs. Calibration of the model for the EU-15 member states provides the following results: i) the maximum tax revenue level is relatively far from the current tax levels for most countries; ii) the cases of Sweden, Denmark and Finland are anomalous, as productive efficiency can be gained by lowering tax rates without affecting fiscal revenues; iii) in general, countries would obtain efficiency gains without changing fiscal revenues by reducing the capital tax and increasing the labor tax; and iv) capital tax harmonization to the average capital tax rate can be done with quite small changes in both fiscal revenues and output for most countries.     

Social norms and economic growth in a model with labor and capital income tax evasion

Empirical evidence suggests that low-income countries are characterized by high levels of labor and capital income tax evasion while the opposite is true for high-income countries. This paper proposes a model to study the relationship between economic growth and both types of income tax evasion. We show that the existence of a social norm towards tax compliance generates a complementarity between capital and labor income tax evasion which explains the decline of both the share of evaders in the population and the amount of tax evasion when countries accumulate capital. The model predicts that the level of tax morale is positively correlated with both types of income tax evasion and the level of income per capita, consistent with recent empirical evidence. Finally, a higher tax rate increases the share of evaders in the population and aggregate tax evasion.     

The asset price incidence of capital gains taxes: evidence from the Taxpayer Relief Act of 1997 and publicly-traded real estate firms

We provide new evidence on the asset price incidence of corporate-level investment subsidies by examining the relative stock price performance of publicly traded companies in the real estate industry that should have been differentially affected by the capital gains tax rate reduction enacted in the Taxpayer Relief Act of 1997. By comparing real estate firms that have an organizational structure that allows entities who sell property to it to defer capital gains taxes and that plan to use the structure to acquire property with those that do not, we isolate the effect of the tax cut from industry trends and firm-level heterogeneity. When we examine the time period surrounding the reduction in the capital gains tax rate, our results suggest the tax change was substantially capitalized into lower share prices for these firms and the benefit of the seller’s capital gains tax deferral accrued mainly to the buyer of an appreciated property.     

Capital Mobility—Resource Gains or Losses? How,When, and for Whom?

This paper investigates which of the two types of countries—resource‐rich or resource‐poor—gains from capital market integration and capital tax competition. We develop a framework involving vertical linkages through resource‐based inputs as well as international fiscal linkages between the two types of countries. Our analysis shows that capital market integration causes capital flows from resource‐poor to resource‐rich countries and improves global production efficiency. However, such gains accrue only to resource‐poor countries, and capital mobility might even negatively affect resource‐rich countries. Furthermore, we show that resource‐rich countries can exploit the gains when taxes on capital are available.     

The incidence of heterogeneous residential property taxes

In an economy with multiple tax jurisdictions, the distribution of the burden of heterogeneous residential property taxes is shown to depend on the elasticity of demand for housing, the elasticity of substitution between land and capital in housing production, the elasticity of supply of land to individual tax jurisdictions, and the degree of population mobility between tax jurisdictions. It is demonstrated that the excise effects of the residential property tax may not cancel across jurisdictions and the average rate of tax may overstate or understate the burden on residential capital.     

Redistribution, Fiscal Competition, and the Politics of Economic Integration

The paper examines the consequences of the economic integration of factor markets in a model with two countries that redistribute income among their residents. The social benefits in each country are financed by a source based tax on capital which is democratically chosen by its inhabitants. If either capital or labour is internationally mobile, the countries engage in fiscal competition and the partial integration of capital or labour markets is detrimental to the countries' redistributive ability. A move from partial to full integration, however, may alleviate rather than intensify fiscal competition, particularly, if the two countries face sufficiently similar economic and political conditions. In such a situation, for example, tax competition for mobile capital is softened as the labour market becomes more integrated and even vanishes if both factors are fully mobile. As a result, there is more redistribution in equilibrium and a majority of the population in each country is strictly better off.     

Imperfect Capital Mobility and Local Government Behaviour in a Two‐Period Economy

One clear result in the tax competition literature is that, when head taxes on immobile residents are available, the optimal capital tax rate for local government is zero. However, zero tax rate, when resident taxes are available, is incompatible with the phenomenon actually observed. In most countries, local governments use capital taxes as policy variables for choosing a nonzero tax rate. This paper presents a model of a two‐period economy with imperfect mobile capital to explain the behaviour of local government providing capital subsidies on capital. It further examines an equilibrium tax rate where local government’s objectives include Niskanen‐type revenue‐maximizing.     

Tax Competition and the Distribution of Income*

In this paper, we provide a two-country, two-class model of asymmetric capital tax competition. We show formally that poor people living in small countries can benefit from capital tax competition and therefore they are in favor of it. In order to benefit from capital inflow from larger countries, poor people in smaller countries accept less within-country income redistribution. As a consequence, between-country income inequality is increased by tax competition.     

The role of infrastructure investment and factor productivity in international tax competition

In this paper we use data from 30 developed economies from 1999 to 2014 to analyse the importance of infrastructure investments and factor productivity for explaining international capital tax competition. Our results indicate the existence of intensive tax competition in effective average corporate taxation during this period. It is also suggested that non-tax variables of third countries affect a country's corporate tax policy. Countries whose direct competitors have better infrastructures or are more productive compensate with lower capital taxation. In this way, their infrastructure investment and productivity-enhancing policies are used as strategic substitutes for capital taxation. With regard to the characteristics of closest competitors, we find that corporate tax competition is fiercer among countries that are characterized by similar infrastructure investments and geographical proximity.     

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.     

The Oecd Model Tax Treaty: Tax Competition And Two‐Way Capital Flows*

Model tax treaties do not require tax rate coordination, but do require that either credits or exemptions be applied to repatriated earnings. This contradicts recent models with a single capital exporter where deductions are most efficient. I incorporate the fact that capital flows are typically bilateral. With symmetric countries, credits by both is the unique and efficient treaty equilibrium. This equilibrium weakly dominates the nontreaty equilibrium. With asymmetric countries, the treaty need not offer improvements without tax harmonization. With harmonization, it is always possible to reach efficient capital allocations while increasing both countries' welfares only if neither uses deductions.
