A general proposition on the design of a neutral business tax

A simple and general means of levying a business tax that is ‘neutral’ in the sense that it does not affect the firm's decisions at the margin is discussed. In particular, we analyze the effect of a business tax of our design on the investment decision of the firm. The well-known ‘imputed income’ and ‘immediate write-off’ methods of levying a neutral business tax are found to be special cases of our general tax design. The implication of our results is that a neutral ‘pure profits’ tax can be levied without the informational difficulties of the imputed income method or the cash flow disadvantages of the immediate write-off method.     

RAMSEY TAXES MEET PRICE RIGIDITY

‘Ramsey taxes’ are commodity taxes that minimize deadweight loss. Evidence has shown dramatic differences in the extent of price rigidity across goods: while the prices of some goods change frequently, the prices of other goods seldom change. This paper examines Ramsey taxes in the presence of heterogeneous price rigidity. We find that, to minimize deadweight loss, lower (higher) tax rates should be imposed on goods with rigid prices if their relative prices are too high (low) relative to the would‐be situation of no price stickiness. Intuitively, Ramsey taxes remedy the relative price distortion caused by the price rigidity of some goods. We calibrate our model to data from Taiwan and the USA, showing a significant cut in welfare cost if Ramsey rather than uniform taxes are applied.     

Dividend taxes,corporate investment,and ‘Q’

Taxes on corporate distributions have traditionally been regarded as a ‘double tax’ on corporate income. This view implies that while the total effective tax rate on corporate source income affects real economic decisions, the distribution of this tax burden between the shareholders and the corporation is irrelevant. Recent research has suggested an alternative to this traditional view. One explanation of why firms in the United States pay dividends in spite of the heavy tax liabilities associated with this form of distribution is that the stock market capitalizes the tax payments associated with corporate distributions. This capitalization leaves investors indifferent at the margin between a corporation's decision to pay out dividends or to retain earnings. This alternative view holds that while changes in the dividend tax rate will affect shareholder wealth, they will have no impact on corporate investment decisions.This paper develops econometric tests which distinguish between these two views of dividend taxation. By extending Tobin's ‘q’ theory of investment to incorporate taxes at both the corporate and personal levels, the implications of each view for corporate investment decisions can be derived. The competing views may be tested by comparing the performance of investment equations estimated under each theory's predictions. British time series data are particularly appropriate for testing hypotheses about dividend taxes because of the substantial postwar variation in effective tax rates on corporate distributions. The econometric results suggest that dividend taxes have important effects on investment decisions.

Another note on deadweight loss

In a recent article, J.A. Kay proposed a useful measure of the deadweight loss arising from a commodity tax system. The measure answers the question: How much more would the taxed consumer be willing to pay in a lump sum rather than as a commodity tax? Kay's computation of the marginal deadweight loss does not yield the change in this measure for small changes in commodity tax rates, however. This note clarifies Kay's otherwise excellent contribution, derives the measure for Cobb–Douglas utilities, and examines a useful property of it.     

Tax Competition in Vertically Differentiated Markets with Environmentally Conscious Consumers

This paper analyses the effects of tax competition on environmental product quality, pollution and welfare in a two-country, vertically differentiated, international duopoly, in which consumers are environmentally conscious. The firm in each country chooses first the environmental quality of its product (which reflects the emissions generated in the production process) and then the price. In equilibrium one country will be more polluted than the other because firms choose different levels of environmental quality of their products. We find that a country’s optimal commodity tax is higher if the domestic firm is the more polluting supplier. Furthermore, non-cooperative commodity tax rates are inefficiently high in equilibrium. This is because, in this framework with environmentally aware consumers, commodity taxes affect the choice of firms regarding their emissions. Therefore, a domestic tax reduction not only raises the profits of the foreign firm but also lowers its emission levels, resulting in higher welfare for the other country. We also analyse the optimal cooperative and non-cooperative commodity and emission taxes with border tax adjustments. With these two policy instruments available, commodity taxes are higher.     

Joan Robinson as a teacher

Sraffa's construct, the standard commodity, responds to Ricardo's search for an ‘invariable’ measure of value, since it is a measurement unit invariant to changes in distribution. But Sraffa suggests that there is no ‘counterpart,’ no analogous search or needed construct, for the ‘problem’ of ‘difference’ as distinct from change (‘why two commodities produced by the same quantities of labour are not of the same exchangeable value’). Difference in this sense is crucial to Marx, who distinguishes value and surplus-value from capitalist price and profit in part in order to theorize differences as systematic value transfers. In that effort, Marx repeatedly poses commodities and capitals as ‘aliquot parts’ of the whole, so that profit is a redistributed share of aggregate surplus-value. This paper shows that, when Marx's aliquot part imagery is formalized, the resulting hypothetical system represents a meaningful ‘counterpart,’ a construct with a function in Marx's analysis of difference comparable to that of Sraffa's standard commodity in analyzing distributional change. A Marxian ‘standard system’ posing each commodity as an aliquot part of the social capital (a) defines the needed labor-time unit of social account by homogenizing heterogeneous concrete labors as socially average (‘abstract’) labor while simultaneously (b) allowing the derivation of exchange-value (e.g., capitalist production price) on that scale via summation of directly and indirectly embodied labor. Indeed, Marx's approach to production prices as resulting from an inter-industry redistribution of aggregate surplus-value is shown to be algebraically identical to the calculation of labor-embodied under ‘aliquot part’ production conditions.     

Extension of Oi's price instability theorem

Oi's theorem that product price variability raises the average profit of a single-product perfectly competitive firm is generalized in this paper to cover the case of an n-commodity firm. Under similar conditions to those mentioned by Oi for the single-product case, commodity (factor or product) price instability raises the average profit of an n-commodity perfectly competitive firm.     

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.     

Factor Substitution and Relative Factor Prices

This paper examines the effects of factor endowments on factor prices in a three‐factor, two‐commodity general‐equilibrium model with endogenous commodity demand and prices. Unlike the conventional small open‐economy model that assumes constant commodity prices, factor substitution influences the direction of these effects. When a factor endowment increases, complementarity with the expanding factor benefits an unchanged factor, but substitutability harms it. If the unchanged factors are complements, there is a possibility of a rise in the expanding factor's price. A comparison of this closed‐economy model with the small open‐economy model reveals the role of international trade, which dampens the effect on the expanding factor's price.     

税收政策与居民消费需求——基于结构效应视角的新思考

本文运用税收经济效应原理系统阐释所得税、商品税与财产税对居民消费需求的作用机制,在考察我国税制结构整体状况及其对居民消费需求负面影响的基础上,通过建立动态面板数据模型与采用GMM估计方法实证估计税收政策对居民消费需求的结构效应,结果发现：一方面,财产税挤入居民消费;另一方面,商品税和所得税均挤出居民消费需求,但开征利息税能够显著降低个人所得税对居民消费需求的抑制效应。基于理论分析与实证估计结果,本文认为,政府为了提高税收政策对居民消费需求调节的针对性与激励效果,应充分发挥税收政策的结构效应,积极推进与实行“有增有减”的新一轮税制改革,构建与扩大居民消费需求相协调的税制结构。     

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.     

Differential incidence in the presence of initial distorting taxes

This paper extends the two-sector, two-factor, general-equilibrium analysis of differential tax incidence by considering an initial situation where the government finances a fixed commodity bundle by distorting commodity and factor taxes. This alters the traditional analysis of marginal differential incidence in a fundamental way by necessitating the simultaneous determination of the change in the rental-wage ratio, the change in aggregate welfare and the change in an endogenously adjusting tax parameter. This contributes towards an integration of the study of the excess-burden effects and the distributional effects of a given tax situation.     

The Emergence of the Law of Value in a Dynamic Simple Commodity Economy

Abstract

A dynamic computational model of a simple commodity economy is examined and a theory of the relationship between commodity values, market prices and the efficient division of social labour is developed. The main conclusions are: (i) the labour value of a commodity is an attractor for its market price; (ii) market prices are error signals that function to allocate the available social labour between sectors of production; and (iii) the tendency of prices to approach labour values is the monetary expression of the tendency of a simple commodity economy to allocate social labour efficiently. The model demonstrates that, in the special case of simple commodity production, Marx's law of value can naturally emerge from multiple local exchanges and operate ‘behind the backs’ of actors solely via money flows that place budget constraints on their local evaluations of commodity prices, which are otherwise subjective and unconstrained.     

Commodity taxes under uncertainty

This paper considers the relative distorting effect on output of commodity taxes, specific and ad valorem, in a situation where a firm faces revenue uncertainty. It is shown generally that this effect depends both on the precise nature of the firm's revenue uncertainty and on the degree of its risk aversion. More specifically, the distorting effect of each tax is characterised for a selection of objective functions and uncertain environments. These characterisations are compared in order to show the influence of alternative specifications on the relative distorting effect.     

Cost-benefit analysis and project evaluation: A comparison of alternative approaches

A cost-benefit criterion is devised to identify small projects which increase production efficiency in a small open economy. This productive efficiency criterion requires only local information on the country's technology. Conditions which make this criterion consistent with more complex criteria based on consumers' preferences as well as technology are investigated in the second half of the paper. We find that the appropriate project evaluation criterion depends on what set of tax and transfer instruments the government can vary. Assuming that the government cannot vary tariffs but can vary all commodity taxes, we find that our initial productive efficiency project evaluation criterion is still valid. Assuming that the government cannot vary tariffs or commodity taxes but can vary direct transfers to consumers leads to a different project evaluation criterion, a generalized Harberger-Bruce-Harris criterion.     

外部冲击与中国的通货膨胀

本文在充分考察全球流动性的转化、国际大宗商品价格的传导、人民币汇率升值的紧缩效应、国际利率的影响以及价格扭曲效应为外部冲击所放大等典型化事实基础上,应用扩展的菲利普斯曲线方程和VAR模型对外部冲击影响国内通胀进行了经验研究。计量结果表明:短期内,国际食品价格是导致国内物价上涨的主要因素;国际原油价格对国内物价的影响在中长期逐步上升;人民币升值抑通胀的效果要经过一段时间才能体现出来;国际利率变化对国内物价有影响;全球流动性的转化因央行的有效对冲对物价的直接影响并不明显。综合而言,外部冲击只是导致通胀的因素之一,而GDP增长率仍是影响物价的最主要因素。因此,防止经济增长过快,调整要素价格抑制投资需求膨胀,以及提高汇率机制弹性以增强货币政策独立性并使之成为应对外部冲击的第一道防线,将是治理中国通胀的根本途径。     

Tax subsidies,the rational demand for insurance and the health care crisis

An individual's optimal insurance coverage depends on balancing his gain through avoiding risk against his loss through the distortion of demand. The U.S. tax system subsidizes the purchase of excessive health insurance by excluding employer premium payments from employees' taxable incomes and by permitting the deduction of a portion of individual premiums. The current operational model of demand for health insurance shows that the tax subsidy does substantially increase insurance coverage. Since much of the rise in health care costs can be attributed to the growth of insurance, the tax subsidy is responsible for much of what is widely perceived as a health care crisis.     

Tax rebating of exports and the balance of payments

Tax rebating has recently been given heavy emphasis as a means of improving a country's balance of payments and recommendations have been made for the substitution of taxes that are fully rebated on exports for taxes that are only partly rebated or are not rebated at all. This paper gives the conditions under which tax rebating would improve a country's balance of payments. It shows that whether tax rebating of exports improves the balance of payments or not depends upon the size of the price elasticity and of the import component of exports. It then shows that, with the available evidence concerning the size of the price elasticities and of the import components in a number of European countries, export rebating may harm rather than improve their balances of payments.     

Determinants of the demand for imports of Venezuela

In this study we use disaggregated annual data to estimate real income and relative price elasticities of demand for imports of Venezuela. After comparing our estimates with those of previous studies, we conclude that (1) Venezuela has made progress in developing domestic substitutes for imports, and (2) the degree of ‘openness’ in Venezuela increased after 1961. We also find evidence that during the period 1974–1979, the increase in the market value of Venezuela's oil reserves led to an increase in all categories of imports.
