Capital Mobility and Source-Based Taxation of Capital Income in Small Open Economies

This paper examines the taxation of capital income in a small open economy that faces a highly elastic supply of internationally mobile capital and increasing tax competition. The analysis considers a wide variety of additional factors that affect the determination of capital income taxation policy, including the desire to tax economic rents earned by foreign and domestic firms, the desire to take advantage of any treasury transfer effects, the role played by transfer pricing and other financial accounting manipulations by foreign multinationals, the need for a backstop to the personal income tax and various political concerns. The paper evaluates several potential income and consumption-based tax reforms in this context. JEL Code: H21, H25, H87     

The Marginal Cost of Funds and the Shadow Prices of Public Sector Inputs and Outputs

Existing studies on the marginal cost of funds (MCF) do not incorporate the public sector inputs explicitly. Incorporating labor and capital as public sector inputs raises questions concerning the definition and the usage of the MCF, and its relation to public sector shadow prices. This paper finds that the MCF should be defined based on the excess revenue rather than the gross revenue; that general equilibrium effects on individuals' net income and government's inframarginal expenditures should be incorporated; and that the MCF measures an element in the shadow price that is solely attributable to the marginal financing, justifying the role of the MCF in cost-benefit analysis and tax reform.     

An Investigation into Alternative Representations of the Marginal Cost of Public Funds

The literature on the marginal cost of public funds (MCF) and the marginal excess burden is presently a very rich one. A problem with this literature, is that several different measures are interpreted as MCF. This paper derives and compares some commonly used measures, and introduces an alternative. Performing a cross-comparison of the various measures seems to be a useful exercise in order to be able to distinguish between which measure is telling us what. Such a taxonomy might clarify the sense in which the different concepts should be used in future writings on this field.     

Why Capital Income Taxes Survive in Open Economies: The Role of Multinational Firms

This paper discusses the role of multinational firms and double taxation treaties for corporate income taxation in open economies. We show that it is optimal for a small open economy to levy positive corporate income taxes if multinational firms are taxed according to the full taxation after deduction system or the foreign tax credit system. Positive corporate taxes also occur in the asymmetric case where some countries apply the exemption system and others apply the tax credit system. If all countries apply the exemption system, the optimal corporate income tax is zero. We also show that, under tax competition, corporate income taxes are not necessarily too low from the perspective of the economy as a whole. While the undertaxation result is confirmed for the case of the exemption system, tax rates may also be inefficiently high if the deduction or the credit systems are applied.     

Strategic Capital Taxation in Large Open Economies with Mobile Capital

The purpose of this paper is to provide a methodologyfor computing time-consistent, strategic capital taxes in a largeopen economy and to analyze the nature of these taxes. Our resultssuggest that even if a full set of nondistortionary taxes isunavailable and even if the government has redistributive goals,the country which imports capital should tax corporate capitaland the capital exporter should subsidize it. We perform comparativestatics experiments to show how strategically chosen taxes varywith the parameters of the model. JEL classifications: H21,E62     

The Importance of Asymmetric Tax Policy and Dangers of Aggregation

Existing tax policies have many complex features that make distinctions across goods, factors, and financial structures that distort economic allocations. Their importance is ignored when tax policy is summarized by an “effective” tax rate. In fact, the losses due to asymmetries are often larger than the losses due to the level of taxation.     

Equity Returns and Business Cycles in Small Open Economies

This is the first paper in the dynamic stochastic general equilibrium literature to match key business cycle moments and long‐run equity returns in a small open economy with production. These results are achieved by introducing four modifications to a standard real business cycle model: (i) borrowing and lending costs are imposed to increase the volatility of the marginal rate of substitution over time, (ii) capital adjustment costs are assumed to make equity returns more volatile, (iii) GHH preferences are employed to smooth consumption, and (iv) a working capital constraint to generate countercyclical trade balances. Our results are based on data from Argentina, Brazil, and Chile.     

Personal Taxation and Investment Incentives in a Small Open Economy

A simple portfolio model is used to investigate the effects of personal taxes on real investment incentives in a small open economy with large and small firms. When shares in large firms can be traded internationally and their rate of return is exogenously determined on international equity markets, a tax on the return on riskless bonds will induce a portfolio shift from bonds to shares in large firms. This shift reduces the impact of the bond tax on the required rate of return on shares in domestically owned small firms, provided that returns on shares in small and large firms are positively correlated. The total impact of the bond tax may even change from a negative to a counter-intuitive positive one if the “beta” between the returns on small and large firms is above unity. A personal tax on equity returns does in general have an ambiguous impact on the pre-tax rate of return requirement of domestically owned firms. An exogenous rate of return on large company shares is shown to enhance the possibility for the equity tax to reduce the required pre-tax rate of return in small domestic firms. A sufficient condition for a negative relationship is again that the “beta” between the returns in small and large firms is above unity.

Determinacy and Learnability of Monetary Policy Rules in Small Open Economies

This paper evaluates under which conditions different Taylor-type rules lead to determinacy and expectational stability (E-stability) of rational expectations equilibrium in a simple "New Keynesian" small open economy model, developed by Gali and Monacelli (2005) . In particular, we extend Bullard and Mitra (2002) results of determinacy and E-stability in a closed economy to this small open economy framework. Our results highlight an important link between the Taylor principle and both determinacy and learnability of equilibrium in small open economies. More importantly, the degree of openness coupled with the nature of the policy rule adopted by the monetary authorities might change this link in important ways. A key finding is that, contrary to Bullard and Mitra, expectations-based rules that involve the consumer price inflation and/or the nominal exchange rate limit the region of E-stability and the Taylor Principle does not guarantee E-stability. We also show that some forms of managed exchange rate rules can help to alleviate problems of both indeterminacy and expectational instability, yet these rules might not be desirable since they can promote greater volatility in the economy.     

Optimal Capital Income Taxes and Capital Controls in Small Open Economies

This paper studies the optimal taxation of capital income in a simplemodel of a small open economy where domestic residents can evade taxeson their foreign investment income. The national government can onlytax domestic capital income and can impose capital controls, whichhowever absorb real resources. The design of optimal policy in thismodel depends on the revenue needs of the government. For relativelylow levels of government expenditures, it turns out that the countrydoes not levy capital income taxes but may restrict capital exports.Otherwise, the country taxes domestic capital income and sets capitalcontrols such that capital exports are driven to zero, at an optimum.In contrast to other models with capital controls it turns out thatthis policy can lead to underinvestment in domestic capital.JEL Classification Number: E 62, F 41, H 21     

Effects of Monetary Policy Coordination on Small Open Economies

This paper proposes an innovative approach for analyzing the influence of external shocks on small open economies. This approach incorporates the role of large-country monetary policy coordination in influencing shocks and provides an empirical tool to analyze them. In the face of recent fluctuations in commodity prices, this new tool makes it possible to evaluate the influence on small countries of large-country policy coordination in response to these shocks. Based on an analysis of data from Mexico, such policies are found to provide better results for Mexico when Mexico's trade partners coordinated their responses.     

Public Investment Criteria in Overlapping Generations Models of Open Economies

This paper derives criteria for worthwhile public investment in an overlapping generations model of an “almost small” open economy- an economy with access to external funding at a given interest rate, but with some influence over its temporal terms of trade. If the economy is dynamically efficient (i.e. the interest rate exceeds the growth rate), committed to free trade, public investment is debt financed and lump sum taxes are feasible, two results follow. First, the “social opportunity cost of public funds” will exceed the government's borrowing rate because of the adverse effect of government borrowing on the terms of trade. Second, the marginal rate of return on worthwhile public investment will be greater than the social opportunity cost of public funds if public and private investment are complements (substitutes) and the tax on capital is below (above) the rate that minimizes the steady state burden of servicing the debt.

The Role of the Personal Tax System in Old‐Age Support: A Survey of 15 Countries

This paper examines the tax treatment of pensioners in 15 industrialised countries. Using a standard methodology, it calculates the average and marginal tax rates of older people and compares them with those of people of working age. These are then combined with a model of pension entitlements in different countries. This shows that tax differentials play an important role in old‐age support. We discuss the appropriate way for the tax system to support pensioners and the implications for the tax treatment of private pensions.     

Public Pressure and Corporate Tax Behavior

We use a shock to the public scrutiny of firm subsidiary locations to investigate whether that scrutiny leads to changes in firms’ disclosure and corporate tax avoidance behavior. ActionAid International, a nonprofit activist group, levied public pressure on noncompliant U.K. firms in the FTSE 100 to comply with a rule requiring U.K. firms to disclose the location of all of their subsidiaries. We use this setting to examine whether the public pressure led scrutinized firms to increase their subsidiary disclosure, decrease tax avoidance, and reduce the use of subsidiaries in tax haven countries compared to other firms in the FTSE 100 not affected by the public pressure. The evidence suggests that the public scrutiny sufficiently changed the costs and benefits of tax avoidance such that tax expense increased for scrutinized firms. The results suggest that public pressure from outside activist groups can exert a significant influence on the behavior of large, publicly traded firms. Our findings extend prior research that has had little success documenting an empirical relation between public scrutiny of tax avoidance and firm behavior.     

News and Business Cycles in Open Economies

We study the effects of news about future total factor productivity (TFP) in a small open economy. We show that an open‐economy version of the neoclassical model produces a recession in response to good news about future TFP. We propose an open‐economy model that generates comovement in response to TFP news. The key elements of our model are a weak short‐run wealth effect on the labor supply and adjustment costs to labor and investment. We show that our model also generates comovement in response to news about future investment‐specific technical change and to “sudden stops.”     

Regime Change and the Role of International Markets on the Stock Returns of Small Open Economies

We examine the influence of US, UK and German macroeconomic and financial variables on the stock returns of two relatively small, open European economies, Ireland and Denmark. Within a nonlinear framework, we allow for time variation via regime switching using a smooth transition regression (STR) model. We find that US (global) and UK and German (regional) stock returns are significant determinants of returns in both markets. Further, global information represented by oil and US asset price movements drive changes between states in each market. Significantly, the role of country‐specific domestic variables is typically confined to a single state while global and regional variables pervade all states.     

The Reaction of Closed End Funds to Stock Distribution Announcements

This study examines the impact of stock split and stock dividend announcements made by closed end mutual funds. We argue that the asymmetric information / signaling hypothesis does not apply to mutual funds. Therefore, any announcement effects must be attributed to other factors such as the optimal trading range hypothesis. We find that closed end funds react no differently than other firms to stock distribution announcements; also, trading volume and turnover remain unchanged after closed end funds' ex-stock distribution days, while liquidity declines for other firms that distribute shares.     

The Elasticity of Taxable Income in New Zealand*

This paper reports estimates of the elasticity of taxable income with respect to the net‐of‐tax rate for New Zealand taxpayers. The relative stability of the New Zealand personal income tax system, in terms of marginal rates, thresholds and the tax base, provides helpful conditions for deriving these estimates. The elasticity of taxable income was estimated to be substantially higher for the highest income groups. Changes in the timing of income flows for the higher income recipients were found to be an important response to the announcement of a new higher rate bracket. The marginal welfare costs of personal income taxation were consistent across years, being relatively small for all but the higher tax brackets. For the top marginal rate bracket of 39 per cent, the welfare cost of raising an extra dollar of tax revenue was estimated to be well in excess of a dollar. Implications of the findings are that: disincentive effects of high top marginal rates can be substantial even when labour supply responses are small; the welfare costs of increases in top marginal tax rates can be high; and announcement effects of tax policy changes can lead to considerable income shifting between time periods.

The tax treatment of UK defined contribution pension schemes

The paper aims to clarify the tax status of pension schemes in the UK and, by using economic and other arguments, to establish a theoretical benchmark that could be considered the ‘appropriate’ tax regime for pension saving. We consider existing tax regimes for saving (such as the ‘ISA’ regime) and theoretical regimes (such as a pure expenditure tax and a comprehensive income tax) and we compare the costs different tax regimes impose on defined contribution pension schemes. We conclude that an expenditure tax is an appropriate benchmark tax regime for pension saving, and that other tax regimes impose additional financial as well as administrative costs.
