The distribution of abilities and the progressive income tax

This paper develops a model of endogenous labor supply, where agents are uncertain about their future wages. Assuming risk aversion, some redistributive taxation is thus warranted. It is shown that, for a particular parameterization of the tax system, an optimally progressive income tax exists. Comparative ststics analysis demonstrates how this tax system is effected by changes in the wage distribution. The paper ends with a discussion of whether an optimally progressive income tax can be politically sustained. It is shown that generally this is not the case in a political system with majority voting.     

Accounting for the family in European income tax systems

Tax systems are expected to achieve many things at once andthis paper discusses the trade-offs involved in attempting toreconcile conflicting aims. It surveys the various instrumentsthat are used to take account of marriage and the presence ofchildren and describes the current systems in the 15 EuropeanUnion countries. The impact of alternative tax treatments ofthe family 'borrowed' from other countries is examined for theUK, using the tax-benefit microsimulation model, POLIMOD. Thepaper explores the implications of the alternatives for thetax paid by families of different types and for the work incentivesof individuals in different family situations.

On the existence of an implementable optimal income tax

Summary. This paper discusses the existence of an optimal income tax and distinguishes itself from the previous articles in two respects. In previous papers, the self selection condition was not necessarily consistent with the individual budget constraint. Furthermore, implementability in previous papers was implicit in individual ability, rather than individual income, as the basis of the tax function. We offer a different concept of the self selection conditions: Anti Normal Envy that is consistent with the individual budget constraint and that we show to be equivalent to the competitive equilibrium under a tax function based on income. We then establish the existence of an implementable optimal income tax.Received: 9 December 2000, Revised: 5 August 2003, JEL Classification Numbers: H21, C62, D59.Correspondence to: Jun IritaniThe authors are grateful to an anonymous referee of this journal whose suggestions were instrumental to our revision of the paper, and to Professors Takao Kataoka, Tomoyuki Kamo, Tetsuya Kishimoto, and Mototsugu Fukushige, and the members of the Kobe-Osaka Joint Seminar in Mathematical Economics, for their invaluable comments.     

Replacing the U.S. income tax with a progressive consumption tax: A sequenced general equilibrium approach

This paper examines the welfare consequences of changing the current U.S. income tax system to a progressive consumption tax. We compute a sequence of single period equilibria in which savings decisions depend on the expected future return to capital. In the presence of existing income taxes, the U.S. economy is assumed to lie on a balanced growth path. With the change to a consumption tax, individuals save more and initially consume less. As the capital stock grows, consumption eventually overtakes that of the original path, and the economy approaches the new balanced growth path with higher consumption and a greater capital stock. Both the transition and the balanced growth paths enter our welfare evaluations. We find the discounted present value of the stream of net gains is approximately $650 billion in 1973 dollars, just over 1 percent of the discounted present value of national income. Larger gains occur if further reform of capital income taxation accompanies the change. We examine the sensitivity of the results, both to the design of the consumption tax and to the values of elasticity and other parameters. The paper also contains estimates of the time required to adjust from one growth path to the other.

Consumer anticipation of income tax changes

The paper synthesizes existing consumption theories to suggest that consumers modify their consumption, savings, debt, and asset acquisition behavior in advance of well-publicized changes in federal personal income tax changes. Existing cross-section and time series data document such adjustments prior to enactment of the 1964, 1968, and 1975 federal income tax revisions. Uncertainty reinforces tax-increase anticipation effects and moderates tax decrease anticipation effects. Further, the response to actual tax changes is reduced, and may even be offset, by consumers' anticipatory actions. The theory and data presented help resolve controversy surrounding the effectiveness of the 1968 tax increase.     

企业所得税并轨对我国引进外国直接投资的影响

我国将要进行的内外资企业所得税并轨会使外资企业所得税负有所提高,来自中国香港和台湾地区的直接以及来自维尔京群岛、开曼群岛和新加坡等国际避税地的外国直接投资,很可能会因此转移到其他国家;而来自美国、欧盟及日本等发达国家的外国直接投资受到的影响则较小。但由于目前我国来自中国香港、台湾地区以及一些国际避税地的直接投资占有绝对的优势,已将近总额的60%,因此提高外资企业所得税率很可能会导致大量外资流向周边低税国家,从而对我国引进外国直接投资的总量产生较大影响。     

A simulation study of income tax evasion

In a game-simulation context, tax evasion behavior of 15 subjects was observed. Large fines were found to be more effective deterrents than frequent audits. The decision to underreport income appears to be influenced by different factors than the magnitude of underreporting. Tax evasion behavior differed widely among individuals.     

The uniform enterprise income tax reform in China

In China, the income tax of enterprise is very different between foreign funded enterprises and other domestic enterprises. It is believed that this discrimination is harmful to the entire economy. So there is a reform in the tax system to build a uniform enterprise income tax. This is a significant reform in China＇s tax system, so every decision about this have to count the cost and the benefit carefully. The author has introduced the Computable General Equilibrium （CGE） to simulate this new tax system and value its benefit and cost. There are two different models in the paper; they are of different assumptions and for different purposes. Model I is a static CGE model and model II is a Ramsey Dynamic model. The static model is mainly used for comparative static approach to examine how the tax reform will change the endogenous variables. According to the results of the model, more goods will be produced by both of the DFEs and FIEs after the tax reform in the medium and low tax effective tax rate situations. If the nominal tax rates decrease 24.24% （from 33% to 25%）, the enterprise income tax will only reduce 19.36% and the total tax revenue will only reduce 1.911%. The dynamic model will concentrate on the costs and benefits during the transition. From the results of the model, a lower tax rate will increase the level of investment, capital stock, capital prices, wage rate and also the growth rates through transition. If the capital tax rates are changed gradually, the fluctuating of transition will be smoothed a little.     

The corporate income tax in an open economy

The paper begins with a brief review of the distortion literature, stressing its relation to the general equilibrium consequences of the corporate income tax. The consequences for international trade of the distortions associated with the tax are then examined, and among other things it is found that trade could reduce welfare. Finally, the implications of trade for the incidence question are examined, and it is shown that whether labor or capital bears the burden of the tax depends entirely on whether the tax is imposed in the labor-intensive or the capital-intensive industry.     

Savings neutrality for the new personal income tax in Spain

The primary aim of this research is to identify to which extent alternative ways of savings are treated differently by the Spanish personal income tax before and after the tax reform of 1998. The proposed measure for appraising savings tax neutrality is based on the methodology of effective tax rates, originally developed by King and Fullerton [1983a, 1983b] and adapted to the Spanish case by González-Páramo [1991, 1995] and González-Páramo and Badenes [1999]. In light of the results, support is found for the expected lack of neutrality under the 18/91 law and the 40/98 law. However, in the savings taxation arena, it is possible to appreciate a trend toward greater doses of simplicity and neutrality as means of a closer treatment between capital income and capital gains returns.This project was funded by the Distance Teaching National University.     

Simulating the revenue elasticity of an individual income tax

The revenue elasticity of an idealized income tax depends upon the threshold, median income and income inequality. Numerical simulations facilitate comparison of elasticities in different economies and underline the dangers of the constant elasticity assumption in certain cross-sectional studies.

Intermediate goods and the incidence of the corporation income tax

Intermediate goods are introduced into a general equilibrium model of the incidence of the corporation income tax. Several theoretical conclusions about the role of such goods are established. Many well-known propositions about the incidence of the corporation income tax, emanating from models with only final goods, need to be modified. Estimates from U.S. data suggest that if intermediate goods are left out results will be misleading, especially if these goods are a relatively large sector in the economy and possibilities of substituting capital for labor in their production, and of substituting them for other productive factors in the final-good industries, are rather limited.
