Outward foreign direct investment and sovereign risks in developing host country

Outward foreign direct investment can affect developing, technology-receiving host countries mainly through tax revenue, technology spillover and the competition effect. With the consideration of these three effects of the outward foreign direct investment on host country, we develop a dynamic game model of interaction between foreign investors and host country from a dynamic perspective, to reveal the dynamic evolution mechanism of the sovereign risk faced by outward foreign direct investment. The result shows that: host governments usually give a specific tax holiday for outward foreign direct investors, and during the period of tax holiday investment decision of investors would be influenced by technology spillover effect, specifically, the greater the technology spillover the slower the growth of investment stock. Once the system reaches a stable state, the host country will impose a tax on multinational corporations. If the equilibrium tax rate of industries or regions which makes it easy to obtain technology spillover is high, then the equilibrium capital stock would be low.     

Capital and Consumption Tax Reforms in a Small Open Economy

The effects of a reform in capital and consumption taxes on private welfare and government tax revenue are examined for a small open, capital‐importing economy. A trade‐off between private welfare and tax revenue is encountered in maximizing social welfare. Nonetheless, lowering capital taxes and raising consumption taxes can increase both private welfare and tax revenue if the initial tax rates are not optimal. In addition, a tax reform by this fashion is a likely response to a rise in the foreign rate of return on capital.     

Dynamic inconsistency and non-preferential taxation of foreign capital

When capital is sunk after it is invested, a host government facing heterogeneous foreign investors has a strong incentive to reduce preferential taxes over time in order to attract less eager investors while fully expropriating past investors. This induces investors to wait rather than invest in the initial period, and leads to loss of tax revenue. This dynamic inconsistency problem is resolved if the host government commits to non-preferential taxation in each period even if it does not commit to future tax rates.     

Some aspects of the taxation of capital gains

The analysis of the effects of capital gains taxation requires a careful modelling both of the details of the tax code and the imperfections in the capital market. Under the standard assumptions concerning perfect capital markets and under the standard idealizations of the tax code, there are several strategies by which rational investors can avoid note only all taxes on their capital income, but also all taxes on their wage income; these strategies leave individuals' consumption and bequests in each state of nature and at each date unchanged from what they would have been in the absence of taxes. Although certain detailed provisions of the tax code may limit the extent to which rational investors can avail themselves of these tax avoidance activities, there are ways, in a perfect capital market, by which the effects of these restrictions can be ameliorated. Accordingly, any analysis of the effects of capital taxation must focus on imperfect capital markets.If individuals face limitations on the amounts which they can borrow and/or if there are limitations on short sales, then under some circumstances there is a locked-in effect (individuals do not sell securities which they would have sold in the absence of taxation); but under other circumstances individuals are induced to sell securities that they otherwise would have held, in order to take advantage of the asymmetric treatment of short-term losses and long-term gains. A policy of realizing gains as soon as they become eligible for long term treatment dominates the policy of postponing the realization of capital gains, provided the gains are not too large.A simple general equilibrium model is constructed within which it is shown that the taxation of capital gains may increase the volatility of asset prices, and lead individuals not to trade when they otherwise would. While the analysis casts doubt on the significance of the welfare losses resulting from these exchange inefficiencies, there are circumstances in which the tax leads to production inefficiencies, e.g. terminating projects at other than the socially optimal date.Finally, we argue that the focus of some recent policy debates on the short-run revenue impact of a decrease in the tax rate on capital gains is misplaced: even when the short-run revenue impact is positive, consumption may increase (thus exacerbating inflationary pressures) and private savings may decrease (thus leading to a lower level of investment in the private sector). Moreover, there is some presumption that the long-run revenue impact is negative.Our analysis has some important implications for empirical research. In particular, it suggests that the impact of the tax is not adequately summarized by a single number, such as the ‘effective tax rate’ representing the average ratio of tax payments to capital gains. Moreover, the impact of the tax cannot be assessed by looking only at reported capital gains and losses.     

Lessons from the polder: Energy tax design in The Netherlands from a climate change perspective

This paper evaluates energy tax reform in The Netherlands between 1988 and 2002 from a climate change perspective. In particular, the introduction of two (indirect) taxes on energy products is now responsible for a considerable amount of tax revenue from a green tax base. The paper discusses the energy tax base and rate structure from a modern Pigovian tax perspective and illustrates the practical difficulties involved in the indirect and non-uniform taxation of emissions. Also further improvements of the energy tax structure are discussed, such as a better targeting of the energy tax base and tax rate to fuel characteristics.     

Taxing Nothing – Tax Arbitrage and the Vanishing Revenue from Capital Income Taxation

In a one-period model the implications of the German tax code, concerning capital taxation, onto the capital market equilibrium are examined. Therefore, we model a corporation sector subject to the corporation tax and private investors liable to private income taxation. We show that there neither exist any possibilities for local tax arbitrage nor tax clienteles. Extending the model for stocks and derivative financial instruments, the tax base for private capital income taxation vanishes and the tax revenue drops to zero.revised version received September 3, 2003     

绿色与非绿色技术对后续创新影响的比较——“厚此薄彼”还是“双赢策略”

尽管绿色技术一直被认为具有广阔的发展前景,但这些技术在企业间的扩散率却很低。企业在非绿色与绿色技术创新关系上存在“厚此薄彼”的现象。基于1992—2019年中国制造业上市公司专利数据研究发现,相较于非绿色技术,绿色技术的前向引用次数更多,且产生了更大的知识溢出效应,对整个社会后续创新具有更大的正向影响力。此外,由于高能耗行业存在转化成本高、自身知识储备不足等问题,随着能耗水平提升,绿色技术对后续创新的正向影响力逐渐减弱。相较于非国有控股企业,国有控股企业绿色技术对后续创新产生了显著正向影响。该结论对政府设计绿色与非绿色创新“双赢策略”,促进企业从“厚此薄彼”转向绿色与非绿色技术双创新具有重要意义。     

Upstream and downstream pollution taxations in vertically related markets with imperfect competition

When two markets are vertically related, the government can control pollution at the upstream as well as the downstream market levels. This paper employs the stylized model of input price discrimination and compares the effectiveness of upstream and downstream pollution taxations. We consider the situation in which downstream firms have heterogeneous abatement technologies and an upstream monopolist performs input price discrimination against them. In order to mitigate pollution, the government imposes input tax on the intermediate inputs and emission tax on the pollutant. We show that the degree of input price discrimination decreases with a rise in the input tax and increases with a rise in the emission tax. We further examine the effect of a green tax reform in which the government changes the source of taxation from input tax to emission tax. We argue that although this green tax reform may reduce the tax revenue of the government, it will certainly increase social welfare.      

The value added tax: Its causes and consequences

This paper explores the causes and consequences of the remarkable rise of the value added tax (VAT), asking what has shaped its adoption and, in particular, whether it has proved an especially effective form of taxation. It is first shown that a tax innovation, such as the introduction of a VAT, reduces the marginal cost of public funds if and only if it also leads an optimizing government to increase the tax ratio. This leads to the estimation, on a panel of 143 countries for 25 years, of a system describing both the probability of VAT adoption and the revenue impact of the VAT. The results point to a rich set of determinants of VAT adoption, and to a significant but complex impact on the revenue ratio. The estimates suggest, very tentatively, that most countries which have adopted a VAT have thereby gained a more effective tax instrument, though this is less apparent in sub-Saharan Africa.     

Multistage public education,voting, and income distribution

This paper proposes a theory to study the formulation of education policies and human capital accumulation. The government collects income taxes and allocates tax revenue to primary and higher education. The tax rate and the allocation rule are both endogenously determined through majority voting. The tax rate is kept at a low level, and public funding for higher education is not supported unless the majority of individuals have human capital above some threshold. Although public support for higher education promotes aggregate human capital accumulation, it may create long-run income inequality because the poor are excluded from higher education.     

新能源成本不确定下能源最优开采研究

随着全球气候变暖和环境的恶化,低污染高效率的新能源成为各国能源政策的主要发展对象,因此新能源取代传统能源是大势所趋。针对未来新能源对传统能源的替代趋势,本文通过建立基于社会和企业总效益最大化的能源最优开采的动态模型,分析了新能源成本不确定性和社会风险偏好的差异对能源耗竭速度的影响,并提出了提高社会总收益的合理方案。分析表明：在替代品出现之前能源的开采量随着新能源替代品成本不确定性的增加而增加;而社会风险厌恶倾向于减少社会的最优开采,但是会增加竞争性企业的的开采量;对T时刻之前的能源开采征收额外的税收可以减缓能源耗竭速度,增加社会总收益。最后,本文提出了T时刻之前的能源开采征收额外的税收,或者是对T时刻之后的能源开采进行补贴来实现我国能源最优开采,提高能源利用效率的建议。     

Public investment,taxation, and long-run output in economies with multi-level governments

This paper examines the dynamic effects of taxation and investment on the steady state output level of an economy. A simple neoclassical growth model with different tiers of government is developed. The initial focus is on governments that aim to maximise their citizens' welfare and economic performance by providing consumption goods for private consumption and public capital for private production. It is shown that a long-run per capita output maximising tax rate can be derived and that there also exists an optimal degree of fiscal decentralisation. The analysis then extends to the case where governments attempt instead to maximise their own tax revenue to fund expenditures which do not contribute to the utility of their citizens. Three different cases of taxation arrangement are considered: tax competition, tax sharing, and tax coordination. The modeling shows that intensifying tax competition will lead to an increase in the aggregate tax rate as compared to the cases of sharing and coordination amongst governments. These tax rates are both higher than the long-run per capita output maximising rate that was implied under the welfare maximising government scenario.     

Tax effort performance in sub-Sahara Africa and the role of colonialism

Governments in sub-Sahara Africa (SSA) have tended to rely unduly on foreign aid and debt financing for the provision of public goods such as health, basic education and infrastructure. Domestic tax revenue could play a significant role in funding such expenditures. However, to date tax revenue collection in SSA has only averaged about 15% of GDP. In this paper we employ cluster analysis to enhance our understanding in the variations in tax effort performance amongst SSA countries. Past studies of tax effort performance in SSA have resorted to economic events or factors to explain the tax effort performance. We argue here that it is necessary to consider historical events to provide a fuller explanation. We provide evidence to show that the different colonial policies pursued in SSA have had a long lasting and profound effect on the countries' tax revenue performance.     

Tax incentives and the decision to purchase long-term care insurance

This paper studies the impact of the tax incentive prescribed in the Health Insurance Portability and Accountability Act of 1996 (HIPAA) on individuals' long-term care insurance purchasing behavior. Using data from the Health and Retirement Study, we find that the tax incentive in HIPAA increased the take-up rate of private LTC insurance by 3.3 percentage points, or 25%, for those eligible. Despite this seemingly strong response, our results imply that even an above-the-line tax deduction would not increase the coverage rate of seniors beyond 13%, indicating that tax incentives alone are unlikely to expand the market substantially. We also present, to our knowledge, the first estimate of the price elasticity of demand for LTC insurance of around ? 3.9, suggesting that demand is highly elastic at the current low ownership rate. Finally, we evaluate the net fiscal impact of the tax incentive and find that the tax deductibility of LTC insurance premiums leads to a net revenue loss for the government, as the reduced tax revenue from granting the tax incentive exceeds the savings in Medicaid's LTC expenditures.     

The Tax‐rate Elasticity of Local Business Profits

Local business profits respond to local business tax (LBT) rates that vary across municipalities. We estimate that a 1% increase in the LBT rate decreases the LBT base by 0.45%, based on the universe of German LBT return files, which include corporations and unincorporated businesses. However, the fiscal equalization scheme largely compensates municipalities for the loss in the LBT base when they increase the LBT rate. Our estimates suggest that using tax revenue data instead of tax return data, as commonly done in the literature, results in a significant bias of the elasticity away from zero.     

Green Tax Reform and Competitiveness

This paper studies a revenue-neutral green tax reform that substitutes energy for wage taxes in an open economy with unemployment. As long as the labour tax rate exceeds the energy tax rate, such a reform will increase employment, reduce the domestic firms' unit cost of production and hence increase international competitiveness and output of the economy. The driving force behind these results is the technological substitution process that a green tax reform will bring about. The resulting reduction in unemployment is welfare increasing since energy, which the country has to buy at its true national opportunity cost, is replaced with labour, whose price is above its social opportunity cost.     

The macro-economic impact of changing the rate of corporation tax

This paper considers the impact of changes in the rate of corporation tax in Ireland affecting the business and financial services sector. A model is estimated that relates services exports and output to world activity, competitiveness and the rate of corporation tax. This model indicates that a reduction in the rate of corporation tax in the 1990s stimulated exports and, even allowing for profit repatriations by foreign firms and replacement of lost tax revenue, it resulted in an increase in domestic output. The increase in profitability suggests that some of the increased output involved relocation of profits to Ireland by multinational firms.     

投资者恶性增资行为的控制机制探讨——基于原生性认知和负反馈信息明确化的考察

本文探讨了在资本预算项目决策中,投资者恶性增资行为的控制机制。文中首先提出了同时使用相对降低投资者的原生性认知和使负反馈信息明确化两种途径,可有效地抑制投资者的恶性增资行为。采用综合设定项目最低报酬率方式可同时达到这一目的。其次,本文运用模拟实验法对该观点进行了验证。验证结果表明：综合设定项目最低报酬率的方式既能有效地抑制恶性增资行为,又可以使设定的最低报酬率与公司期望的最低报酬率无显著差异。     

我国节能减排税收政策效应研究

税收政策是我国促进节能减排的重要工具之一。采用Engle-Granger协整检验方法,对我国节能减排税收政策效应的实证研究结果表明,从长期看,节能减排税收收入与我国单位GDP能耗之间存在协整关系,但各个税种的节能减排效应差异较大。其中,增值税的节能减排效果显著,但仍有改善空间,而消费税和资源税并未发挥应有的作用。因此,建议通过全面改革资源税制、扩大消费税征税范围以及优化增值税税率等系列措施,促进我国节能减排税收政策效应的发挥。     

MONETARY EXPANSION AND PRODUCTIVE PUBLIC EXPENDITURE IN A CASH‐IN‐ADVANCE ECONOMY*

Using a dynamic optimization model that incorporates a cash‐in‐advance constraint on both consumption and investment and productive public capital financed by a lump‐sum tax and seigniorage, this paper analyses the steady‐state effects of an increase in the inflation rate (the money growth rate) on output, private capital and welfare. The effects are negative at high inflation rates. However, at low inflation rates, the effects depend on the amount of lump‐sum tax revenue collected and therefore are either positive or negative.
