Laffer curves in Japan

This paper investigates the Laffer curves in Japan, based on a neoclassical growth model. It is found that while the labor tax rate is smaller than that at the peak of the Laffer curve, the capital tax rate is either very close to, or larger than, that at the peak of the Laffer curve. This problem is more serious when the consumption tax rate is high. It is also found that to maximize total tax revenue, the government should increase the labor tax rate but decrease the capital tax rate.     

Welfare cost of higher tax rates: An empirical laffer curve for The Netherlands

Summary On the basis of a simple general equilibrium model calculations are made of the welfare cost of higher tax rates. Furthermore, the Laffer curve for The Netherlands is estimated. Taking 1970 as the basic year and assuming that all tax revenues were paid back in lump-sum benefits, the Laffer curve topped at a marginal rate of 66.9076 and theMEB stood at 1.24. This means that an additional guilder in tax revenues involves a welfare loss of Dfl. 1.24 on top of the direct tax burden. Considering the true proportion of government income being spent on benefits, the Laffer curve is found at a marginal tax-rate of 70.1016. In that case theMEB amounts to 0.83 in 1970. The most striking finding was the sharp rise in theMEB, from 0.83 in 1970 to 6.36 in 1985. This high welfare cost is an indication that The Netherlands is nearing the limits of taxation on income. It is found that market signals are disturbed most when tax revenues are used for income transfers in a form which does not influence allocation decisions at the margin (lump-sum benefits). In that case relative prices are affected, whereas income effects are neutralized.The authors wish to thank Professor F. W. Rutten, J. van Sinderen and other colleagues at the Directorate for Macro-economic Policy of the Ministry of Economic Affairs for their stimulating support and critical remarks. J. Hulsman translated the original Dutch draft.     

Tax Elasticities and the Impact of Discretionary Tax Measures on Government Revenue in Papua New Guinea, 1975–92

This paper evaluates tax elasticities and the impact of discretionary tax measures on government revenue in Papua New Guinea (PNG) using a dynamic macroeconometric model of taxation which captures the interaction between GDP, individual tax systems and individual tax revenues and bases. Our findings show that economic growth and discretionary tax changes have both been effective in mobilizing additional tax revenue. However, the responsiveness of the individual tax system reflected base-to-GDP elasticity except personal income tax whose elasticity reflected increased tax rates.     

Welfare Effects of Capital Taxation in a Small Open Economy

In a small open economy, the welfare effect of capital taxation depends on the allocation of the tax revenue as well as the tax system. If tax revenues are used to finance debt or government spending, an increase in either residential or territorial capital taxation will reduce the welfare of the representative individual. If tax revenues are transferred intergenerationally, an increase in the residential capital tax rate will increase the steady-state welfare when the after-tax interest rate is greater than the growth rate. If the revenue is rebated to the tax payer, an introduction of territorial capital taxation may increase welfare when the growth rate is relatively high. In the case where either the revenue from residential capital taxation is rebated to the tax payer or the revenue from territorial capital taxation is transferred intergenerationally, the welfare-maximizing tax rate appears to be zero.     

International Capital Competition and Environmental Standards

This paper examines the welfare effects of capital taxation and environmental standards with and without a government spending constraint or international tax credits. This analysis delineates the intricate linkages of the two policy measures to both private income and government welfare. Loosening environmental control leads to more capital tax revenue for the government. The optimal capital tax rate may be of any sign, depending upon the ranking of the weights of government objectives and private utility. The same criterion also applies in determining how stringent the optimal environmental standards should be.

Corporate tax systems and cross country profit shifting

The paper analyses optimal taxation of corporate profits whengovernments can choose both the rate and the base of the corporationtax, but are constrained to collect a given amount of corporatetax revenue. In a standard two-period model of investment andinternational mobility of portfolio capital only, the optimaltax system allows a full deduction for the costs of capital.When foreign direct investment is permitted, however, and firmscan shift profits between countries through transfer pricing,it will be optimal for each government to distort investmentdecisions in order to reduce tax rates and limit the incentivefor profit shifting.     

Optimal Taxation in a Federal System of Governments

This paper demonstrates that the optimal structure of taxation in a federal system of governments is one in which only lower level governments are allowed to tax, and the higher level of government receives its revenues as contributions from the lower level governments. The central inefficiency created when multiple levels are allowed to tax is a revenue externality between governments that is analogous to a common pool problem. A federal system with multiple levels of taxing authority results in combined tax rates higher than would be optimal, a higher excess burden of taxation, and an inefficiency bias in government spending.

Income tax reform for a globalized world: The case for a dual income tax

Countries that are industrialized, or becoming so, must adopt tax systems that are capable of raising considerable amounts of revenue efficiently, equitably and with administrative simplicity, while at the same time coping with the competitive features of a globalized world economy. A component of that tax system will be direct taxation of households alongside general sales and payroll taxation. This paper addresses the role that capital income taxes should play in the income tax system. Arguments for the preferential treatment of capital income are summarized, and a case is made for adopting a schedular approach in which capital and labor income are taxed according to separate rate structures. The particular case of the dual income tax system used in the Nordic countries is advocated whereby capital income is taxed at a low, flat rate and non-capital income is taxed progressively. It is argued that this system best combines the objectives of a good tax system in an internationally competitive environment.     

Taxation in the Tanzanian gold sector: Overview of impacts and possible solutions

This paper analyses the factors that reduce the gold sector's contribution to the Tanzanian government's revenue. Tanzania is among Africa's largest gold exporters. Yet ordinary Tanzanians have seen little benefit from this. This is partly because the government has enacted tax laws that are, as we shall see, overly favourable to multinational mining companies, and partly because of the same companies' business practices. Critics argue that the government fails to capture a substantial amount of state revenue as a result of low royalty rates, unpaid corporate taxes and tax evasion by major gold mine operators. This paper argues that the Tanzanian government should try to increase its share of revenues by taxation based on revenues, increasing its auditing skills and its involvement in mining, as well as by increasing the transparency of contracts and limiting the discretionary power of policy-makers in negotiating contracts.     

Tax policy and reform in Asian countries: Thailand''s perspective

This paper gives overviews of Thailand's tax system covering major taxes administered by the central government and the local taxes administered by the local government. Recent tax reform experiences are discussed at length starting from the introduction of value added tax (VAT) replacing the business tax to customs tariff reform. Current issues on taxation are also highlighted ranging from tax base, direct and indirect taxation, decentralization impediments. Furthermore, the government is implementing modern and cutting-edge technology in tax administration, thereby providing effective and efficient e-government services to the Thai people. This paper discusses the Roadmap for Tax Reform that would outline the framework for future direction of taxation in Thailand. Finally, the paper gives important insights on tax issues, and draws important conclusions for the future of tax reform in Thailand.

Optimal taxation and risk-sharing arrangements in an economic federation

This paper analyzes optimal taxation and risk-sharing arrangementsin an economy with two levels of government. Both levels providepublic goods and finance their expenditures via labor incometaxation, where the tax base is responsive to the private agents'labor supply decisions. The localities are assumed to experiencedifferent random productivity shocks, meaning that the privatelabor supply decision as well as the choices of income tax ratesare carried out under uncertainty. Part of the central government'sdecision problem is then to provide tax revenue sharing betweenthe local governments. The optimal degree of revenue sharingdepends on whether or not the localities/regions differ withrespect to labor supply incentives.     

ECONOMIC GROWTH AND THE STRUCTURE OF TAXES IN SOUTH AFRICA: 1960–2002*

One tenet of taxation is its distorting effect on economic behaviour. Despite the economic inefficiencies resulting from taxation, it is widely believed that taxes impact minimally on the economy's growth rate. Evidence in developing countries generally supports this view. In this paper, we present evidence that tax distortions in South Africa may be much more severe. Using tax and economic data from 1960 to 2002 and a two‐stage modelling technique to control for unobservable business cycle variables, we examine the relationship between total taxation, the mix of taxation and economic growth. We find that decreased tax burdens are strongly associated with increased economic growth potential; in addition, contrary to most theoretical research, decreased indirect taxation relative to direct taxation is strongly correlated with increased economic growth potential.     

The Distributional Effects of the Trump and Clinton Tax Proposals

Hillary Clinton and Donald Trump, the Democratic and Republican candidates for President of the U.S. in 2016, proposed several changes in the federal tax code. Hillary Clinton would add a personal income tax surcharge of 4% on high annual incomes, limit the tax benefits of non-charitable deductions, set a minimum tax rate of 30% on taxpayers earning more than one million dollars a year, increase the tax rates on capital gains for taxpayers in the top tax bracket, and expand the base of the estate tax. Donald Trump would reduce the number of personal income tax rates, increase the standard personal deduction, cut all taxes on business income to no more than 15%, and abolish the inheritance tax. Using a tax calculator model, we estimate the static effects of these very different changes. Over a ten-year period, Clinton’s proposals would raise federal tax revenue by a total of $816 billion, an increase of 1.9% over projected baseline revenue, while Trump’s tax changes would lower tax revenue by $9.8 trillion. Clinton’s higher taxes would reduce incomes and revenue somewhat, while Trump’s tax cuts would potentially boost output substantially. Using an extended simulation model, we find that 86% of the incremental tax burden of Clinton’s tax increases would fall on those in the top tenth of the income distribution. Most other taxpayers would see only minor changes in their tax burdens, and the revenue and redistributive effects of her proposed changes are relatively modest. Meanwhile, 70% of Trump’s tax cuts would go to those in the top decile, and the effects are large, with gains of over $15,000 annually per person for this group, compared to gains of less than $500 per person for the poorest 40% of the population. On tax policy, the two candidates propose strikingly different policies.

Indonesia's new tax reform: Potential and direction

This study aims to provide direction for policy and provide input to improve the quality of taxation services, by emphasizing and analyzing the existing tax potential and recommending a taxation reformation plan in accordance with fiscal sustainability and efforts to increase the level of Indonesian competence both for the transition period and in the long term. The result of the study has indicated that there is still the opportunity to increase national revenue without increasing rates and by increasing the capacity of tax administration and expanding the tax base, tax collection/revenue will increase. There are a number of indicators that illustrate this, such as the ratio of tax revenue to the GDP which is still relatively low compared to other countries, wide scope for increasing value added tax (VAT), PIT and CIT revenue productivity, etc. Our best estimation for potential tax revenue expansion for the next 2–3 years would be 2.1% of GDP where PIT and CIT contributed more than half of that expansion.
