Income Shifting within a Dual Income Tax System: Evidence from the Finnish Tax Reform of 1993*

Dual income tax systems can suffer from income that shifts from progressively taxed labour income to capital income, which is taxed at a lower, flat rate. This paper empirically examines the 1993 Finnish dual income tax reform, which radically reduced the marginal tax rates on capital income for some, but not all, taxpayers. We measure how overall taxable income and the relative shares of capital income and labour income reacted to the reform. We find that the reform led to a small positive impact on overall taxable income, but part of the positive response was probably offset by income shifting among the self‐employed.     

论集群经济中的税收竞争效应

文章首先简单回顾标准/经典国际税收竞争模型的主要内容,然后引入集群经济这一新的经济概念,对集群经济下国际税收竞争模型及其结果进行重新审视,得出的结论是集群经济中的政府倾向于对企业进行补贴,而当存在集群经济的地区与不存在集群经济的地区展开税收竞争时,均衡状态下前者的税率将高于后者.结合我国的实际情况,文章最后提出了集群经济中政府参与税收竞争的一些政策建议.     

Welfare Policy in the Presence of Unionised Labour and Internationally Mobile Firms*

To what extent does the welfare state exacerbate the loss of jobs due to offshoring? We consider a model with oligopolistic sectors that are exposed to offshoring, as well as a unionised labour force that is entitled to unemployment benefits. We find that deeper economic integration induces wage moderation to the point that wages become independent of workers' outside options. Because the entire incidence of redistribution falls on net wages, the unions' willingness to moderate wages is constrained by the level of redistribution. Beyond an upper limit of redistribution, extending the welfare state compels unions to oppose wage moderation at the cost of losing jobs to offshoring. Below that upper limit, however, redistribution becomes less rather than more distortive.     

中国地方财税竞争与异质偏好劳动力的空间流动——以京津冀大都市区为例

文章通过对Hindriks、Rochet和Stole(2002)模型的拓展,将劳动力流动引入含有空间属性的区域财税竞争框架,研究异质性偏好的劳动力的空间流动决策,及其对地方税收竞争一般均衡的影响。文章解析了地方政府效用最大化的税收和支出组合条件、罗尔斯式政府效用与线性政府效用函数下均衡解的影响因素,以及均衡时要素流动性对地方政府效用和地方福利分配的政策影响。研究发现,劳动力流动与地方政府的政策集合、政府效用之间存在相互的决定和影响关系。在罗尔斯式的政府效用设定下,博弈均衡仅与技术工人的流动性有关,但地方再分配的程度与技术工人的流动性成反比。     

Tax Reform,Sector‐specific Labor Supply and Welfare Effects*

This paper focuses in particular on the 1992 tax reform in Norway. In this reform the top marginal tax rates were cut considerably. We find that the impact on overall labor supply is rather modest, but these modest changes shadow for stronger sectoral changes. The tax reform stimulated the women to shift their labor from the public to the private sector and to work longer hours. A calculation of mean compensated variation, calculated within the framework of a random utility model, shows that the richest households benefited far more from the 1992 tax reform than did the poorest households.     

Heterogeneous firms,corporate taxes and export behavior: A firm-level investigation for Italy

This paper analyses the effect of home corporate taxes on a firm’s decision to expand the scale of its activity through exports using a rich dataset on Italian firms. Starting out from the observation that firms’ export activity vary greatly among them and tend to be systematically related to firm’s characteristics, we relate differences in firms’ export choices to firm level incidence of corporate taxes. Our results suggest that (i) corporate taxes matter at both the extensive and the intensive margin and (ii) higher corporate taxes may increase the probability of new firms’ entry in the foreign market while they decrease the export intensity of incumbent exporters.     

Public Provision of Private Goods,Self‐Selection,and Income Tax Avoidance

Redistributive taxation should benefit those with low earnings capacity rather than those who choose a lower income to obtain tax savings. Several contributions have highlighted how public provision of work complements can discourage people from lowering labor supply to diminish taxable income. We show how tax avoidance, previously neglected, can alter the conclusions regarding public provision. Tax avoidance breaks the link between labor supply and reported income. An agent reducing his reported income to escape taxes might no longer forego a publicly provided labor complement, because he can now lower his income by avoiding more rather than working less.     

Revenue Sharing and Information Exchange under Non‐discriminatory Taxation*

The international exchange of tax information, and its merits compared to withholding taxation, has emerged as a central topic in international tax policy. We characterize and compare the outcomes that emerge, in a two‐country world, with and without information exchange, under the assumption that countries are unable to tax residents and non‐residents differentially. The analysis focuses on the role of asymmetries in country size (capturing a key feature of tax havens) and on the impact and potential desirability of schemes to share the revenue raised by withholding (as under the new EU savings tax arrangements) or (more innovatively) as a consequence of information exchange. We show that, irrespective of any difference in country size, it is in the interests of both countries, in terms of tax revenue, that all revenue collected from non‐residents be transferred to the residence country—which would entail taking the EU practice even further from the norm, but is currently the standard in relation to information exchange. A withholding scheme with revenue fully reallocated in this way gives both countries more revenue than does information sharing, whatever the allocation under the latter.

The Finnish Corporate Income Tax Reform and the Financial Strategy of Firms: A General Equilibrium Approach

This paper simulates the effects of the recent Finnish corporate tax reform with a computable general equilibrium model. It shows that the impact of the reform on the capital stock depends on the reactions of firms. If the financial strategy is changed to prefer dividend distribution and share issues, the cost of capital falls and the capital stock increases. On the other hand, if the criterion of financial policy is to minimise the welfare loss of current shareholders, the earlier financial behaviour should be continued. In that case,the induced higher cost of capital leads to a lower capital stock. The overall welfare evaluation of the tax reform is not sensitive to the regime shift: the reform should not have been implemented. This is because the increase in interest income taxation distorts saving decisions, expands the net foreign debt of the economy and weakens the terms of trade.     

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.     

Fiscal Competition and Growth When Capital Is Imperfectly Mobile*

Is tax competition good for economic growth? We address this question using a simple model of endogenous growth. Governments in a system of many small jurisdictions benevolently maximize the welfare of immobile residents. Quadratic (de‐)installation costs limit the mobility of capital. We look at optimal taxation and long‐run growth, and we analyse the effects of cost parameter variations on taxation and growth. A race to the bottom in capital tax rates is only one possibility; the relationship between capital mobility and capital tax rates is not monotonic. Growth and capital mobility are unambiguously positively related.     

Consequences of Environmental Tax Reform for Unemployment and Welfare

We investigate the welfare effects of environmental tax reform, i.e. raising environmental taxes and using the proceeds to reduce distortionary taxes on labour. The framework of analysis is a small open economy with involuntary unemployment due to a rigid consumer wage. Environmental tax reform boosts not only environmental quality but also employment if substitution between labour and resources is easy, the production share of the fixed factor is large, and the initial tax rates on resources and profits are small. If the initial tax system is sub-optimal with a negligible tax on resources, profits rise as well.     

分税制改革、地方政府干预与金融发展效率

文章对1994年的分税制改革在改变中央与地方政府财政收支格局的同时,是否使地方政府施加于金融部门的行为方式也趋于变化作了系统考察。研究显示,正是由于分税制改革切断了财政收入与支出的联系,使得地方政府面临着沉重的财政负担,从而导致了其普遍加强了对金融信贷行为的干预,不利于金融部门发挥其价值发现与企业监管的职能,进而也必然导致金融信贷资金配置的低效率。计量分析结果也有力地支持了上述观点,其政策含义是将财政体制、金融体制和政府体制改革纳入同一个框架中将有利于减少制度转型过程中的“摩擦成本”。     

Tax distortions in Sweden and the United States

We calculate the welfare costs of distortionary taxation (including inflation) in models calibrated for the United States and Sweden. The welfare costs are calculated using comparative steady state as well as dynamic analysis, where we take the costs of transition from the distorted to the optimal steady state into account. We also calculate the welfare costs of adding stochastic fluctuations. Our main finding is that the total welfare costs of the distortionary taxes including the distortionary effects of inflation are about five times higher in Sweden than in the United States. Meanwhile, stochastic fluctuations in policy turn out to have a relatively small impact on welfare.     

Tax Competition,Investment Irreversibility and the Provision of Public Goods

This article studies the effects of tax competition on the provision of public goods under business risk and partial irreversibility of investment. As will be shown, the provision of public goods changes over time and also depends on the business cycle. In particular, under source‐based taxation, in the short term, public goods can be optimally provided during a downturn. The converse is true during a recovery: in this case, they are underprovided. In the long term, however, tax competition does not affect capital accumulation. This means that the provision of public goods is unaffected by taxation.

Monetary Policy,Financial Frictions,and Heterogeneous R&D Firms in an Endogenous Growth Model*

Motivated by empirical facts, I construct an endogenous growth model in which heterogeneous research and development (R&D) firms are financially constrained and use cash to finance R&D investments. I also examine the optimal monetary policy. The effects of financial constraint crucially depend on whether R&D firms are homogeneous or heterogeneous regarding R&D productivity. If R&D firms are homogeneous, then the zero nominal interest rate (i.e., the Friedman rule) is always optimal under severe financial constraint. Heterogeneity in R&D productivity leads to the opposite result. With heterogeneity, severe financial constraint makes the strictly positive nominal interest rate welfare-improving under a plausible condition.
