国际资本异常流动对经济增长具有非线性效应吗?--基于汇率制度和金融市场发展视角

本文基于64个经济体1999-2017年的季度面板数据,采用工具变量广义矩估计(IV-GMM)方法,从汇率制度和金融市场发展视角研究国际资本异常流动对经济增长的非线性效应。研究表明,资本流动激增显著促进了经济增长,资本流动中断、外逃和撤回对经济增长具有负向影响。有弹性的汇率制度显著减弱了四种资本异常流动情形对经济增长的冲击效应;金融市场发展显著降低了激增、中断和撤回对经济增长的冲击影响,强化了外逃对经济增长的冲击效应。随着汇率制度弹性和金融发展程度变化,新兴经济体与发达经济体资本外逃对经济增长的影响呈现明显的异质性。本文结论对于各国防范国际资本异常流动风险、维护国内经济金融稳定,以及稳步有序推进汇率市场化改革和金融市场建设具有重要的参考价值。     

Foreign Direct Investment and Economic Growth in Malaysia: Interactions with Human Capital and Financial Deepening

This paper explores the role of foreign direct investment (FDI) in economic growth in Malaysia, appropriately controlling for other proximate drivers of economic growth: domestic investment, exports, financial markets, and human capital. Domestic capital formation, FDI, human capital, and financial deepening significantly affect economic growth. FDI has a positive and significant effect on economic growth, but its effect is of lesser magnitude than that of domestic investment. Human capital and financial markets interact with FDI and, thus, are important for both short- and long-term growth processes. The results suggest that it is important to encourage domestic as well as foreign investment to put Malaysia back on its precrisis growth path.     

Do corporate tax cuts increase investments?

This paper studies the effect of corporate taxes on investment. Since firms with a foreign parent have more cross-country profit shifting opportunities than domestically owned firms do, their effective tax rate and, consequently, their tax-induced costs to investment are lower. We therefore expect capital investment responses to a corporate tax cut to be heterogeneous across firms. Using firm-level data on German corporations, we exploit the 2008 tax reform, which substantially cut corporate taxes as an exogenous policy shock and expect domestically owned firms' investments to be more responsive to the reform. We show exactly this in a difference-in-differences setting. We find that the reduction in corporate tax payments led to a one-to-one increase in the real investments of domestic firms. The effect is stronger for domestic firms relying more on internal funds. Correspondingly, labor investment increased more for domestic firms, ensuring a constant mix of input factors. In addition, we show that domestic firms' sales grew faster after the tax cut than the sales of foreign-owned firms. Our results imply that corporate tax changes can increase corporate investment but that domestic firms benefit more than foreign-owned firms from a tax cut through higher investment responses resulting in greater sales growth.     

环境税率、双重红利与经济增长

本文构建了一个包含环境税、污染存量和预期寿命的世代交替模型,研究环境税对环境红利和经济发展红利的影响。基于新古典增长模型的研究表明,环境税能够实现双重红利(环境红利和经济发展红利),这契合“绿水青山就是金山银山”的绿色发展理念。从传导机制看,环境税通过负收入效应使得资本积累下降,同时,环境税通过健康效应使得预期寿命延长,这又使得资本积累增加。环境税通过影响资本积累,进而影响环境质量和经济发展。此外,环境税率上升使得用于环境治理的政府支出增加,这使得经济更容易产生环境红利。基于内生增长框架的分析表明,环境税有助于摆脱“环境贫困陷阱”,这为解释国家之间的收入差距提供了一个参考机制。数值模拟结果显示,在新古典增长框架和内生增长框架下,均存在最优的环境税率可以极大化人均产出和经济增长率。本文认为,合理的环境税率有助于推进减污降碳协同治理。     

不同资本账户开放程度下汇率波动对经济增长的非线性效应--基于面板门限模型的分析

文章利用50个国家1997~2015年的年度数据,基于面板门限模型分析了不同资本账户开放度下汇率波动与经济增长之间的非线性效应。研究发现:第一,汇率波动与经济增长之间存在门限效应,具体表现为低汇率波动促进经济增长,高汇率波动抑制经济增长;第二,资本账户开放能够弱化汇率波动对经济增长的不利影响,且不同资本账户开放度存在异质性;第三,不同汇率波动幅度下,汇率波动与资本账户开放度的交互项对经济增长的影响存在门限效应。     

Why hasn’t tax competition triggered a race to the bottom? Some quantitative lessons from the EU

The integration of European financial markets in the early 1980s created an environment of near-perfect capital mobility across countries that had harmonized indirect taxes but maintained large differences in factor taxes. The years that followed witnessed several rounds of competition in capital taxes with puzzling results. Instead of the dreaded “race to the bottom” in capital taxes, the UK lowered its capital tax to a rate closer to those of France, Germany and Italy, while capital taxes changed slightly in these countries. The UK increased its labor tax marginally, but the other countries increased theirs sharply. This paper shows that these results are consistent with the quantitative predictions of a dynamic, Neoclassical general equilibrium model of tax competition that incorporates the key international externalities of tax policy operating via relative prices, wealth distribution and fiscal solvency. Tax competition is modeled as a one-shot game over time-invariant capital taxes with dynamic payoffs relative to a status quo calibrated to European data. The calibration is preceded by an empirical analysis that shows that the relationship linking taxes to labor supply and the investment rate in the model are in line with empirical evidence and that domestic taxes seem to respond to foreign taxes. The solutions of the games show that when countries compete over capital taxes adjusting labor taxes to maintain fiscal solvency, there is no race to the bottom and the Nash equilibrium is close to observed taxes. In contrast, if consumption taxes adjust to maintain fiscal solvency, competition over capital taxes triggers a “race to the bottom,” but this outcome entails large welfare gains. Surprisingly, the gains from coordination are small in all of these experiments.     

Ramsey meets Thünen: the impact of land taxes on economic development and land conservation

Land taxes can increase production in the manufacturing sector and enhance land conservation at the same time, which can lead to overall macroeconomic growth. Existing research emphasizes the non-distorting properties of land taxes (when fixed factors are taxed) as well as growth-enhancing impacts (when asset portfolios are shifted to reproducible capital). This paper furthers the neoclassical perspective on land taxes by endogenizing land allocation decisions in a multi-sector growth model. Based on von Thünen’s observation, agricultural land is created from wilderness through conversion and cultivation, both of which are associated with costs. In the steady state of our general equilibrium model, land taxes not only may reduce land consumption (associated with environmental benefits) but may also affect overall economic output, while leaving wages and interest rates unaffected. When labor productivity is higher in the manufacturing than in the agricultural sector and agricultural and manufactured goods are substitutes (or the economy is open to world trade), land taxes increase aggregate economic output. There is a complex interplay of conservation policy, technological change and land taxes, depending on consumer preferences, sectoral labor productivities and openness-to-trade. Our model introduces a new perspective on land taxes in current policy debates on development, tax reforms as well as forest conservation.     

Efficient Tax Competition with Factor Mobility and Trade: A Note

This note shows that residence- and source-based taxes on capital income are not sufficient to sustain an efficient Nash equilibrium when several goods are internationally traded, apart from two special cases. With several traded commodities, domestic fiscal policies affect foreign welfare not only through changes in the world interest rate but also through changes in the equilibrium relative prices of traded commodities. In order to guarantee the existence of an efficient Nash equilibrium in the general case, additional tax instruments are required. In particular, destination-based taxes on traded commodities are needed to enable the government to control the relative commodity prices faced by domestic consumers. In addition, in order to shield domestic producers from changes in world prices, the government must levy either origin-based commodity taxes or taxes on the immobile factors.     

Optimal Capital Income Taxes and Capital Controls in Small Open Economies

This paper studies the optimal taxation of capital income in a simplemodel of a small open economy where domestic residents can evade taxeson their foreign investment income. The national government can onlytax domestic capital income and can impose capital controls, whichhowever absorb real resources. The design of optimal policy in thismodel depends on the revenue needs of the government. For relativelylow levels of government expenditures, it turns out that the countrydoes not levy capital income taxes but may restrict capital exports.Otherwise, the country taxes domestic capital income and sets capitalcontrols such that capital exports are driven to zero, at an optimum.In contrast to other models with capital controls it turns out thatthis policy can lead to underinvestment in domestic capital.JEL Classification Number: E 62, F 41, H 21     

Corruption and Transparency in a Growth Model

We develop a Ramsey type model of economic growth in which the “Engine of Growth” is public capital accumulation. Public capital is a public good, and is financed by taxes on private output. The government may either use the taxes gathered to fund public capital accumulation or consume the resourses itself; that is engage in corruption. There is an irreducable level of endogenously determined corruption which constitutes rents for which potential governments compete. This competition takes the form of choosing a time path for public capital invesment, which implies time paths for output and household consumption. We study both the model’s steady state, and dynamical behavior along the saddle path. The predictions of our theory accord well with the existent empirical evidence on the relationships between the level and growth rate of output, corruption, public investment and fiscal transparency. Our analysis also provides a perspective on the transition experiences of several Eastern European economies. JEL Code: O41, H41     

Mitigating America's demographic dilemma by pre-funding social security

Financing Social Security benefits at current levels implies significant increases in payroll taxes within the next 20 years under current US demographic developments. Using a general-equilibrium overlapping-generations model with realistic patterns of fertility and lifespan extension, this study shows that future generations would be harmed during the demographic transition due to rising payroll taxes, which crowd out savings and slow real wage growth below the rate of technological progress. A faster rate of technological progress would mitigate only some of the payroll tax increase and its economic consequences but could not overcome them. Addressing the financing problem by reducing Social Security benefits as needed or by raising the eligibility age for benefits imposes major welfare losses on current or near term retirees. By contrast, a pre-funding of Social Security financed with consumption taxes more evenly spreads the welfare losses across generations, and it helps future generations, especially the poor, by stimulating capital formation.     

Government venture capital and cross-border investment

We use data on venture capital investments from 26 countries from 1998–2013. We investigate the following questions: Do domestic government sponsored venture capital funds augment or curtail domestic private venture capital funds from cross-border investment? Do government sponsored venture capital funds attract or repel foreign private venture capital investment? The results show that a preponderance of mixed-structured over pure-structured government venture capital investment has a crowding-in effect overall: it attracts domestic and international private venture capital to the domestic venture capital market while simultaneously increasing total private venture capital investment. In contrast, a preponderance of pure-government over mixed-government venture capital fund investment repels foreign private venture capital investment (has a crowding out effect). We find that both these effects are more pronounced for domestic rather than foreign private venture capital and that the attraction effect is stronger than the repulsion effect.     

Political Sustainability and the Design of Environmental Taxes

This paper studies the issue of political support for environmental taxes. The environmental tax is determined by majority voting, given a refund rule that specifies the allocation of tax proceeds. The refund rule is chosen by a welfare-maximizing constitutional planner. We show that: (i) The equilibrium tax rate is increasing in the proportion of tax reductions based on wage incomes. (ii) If labor and capital income taxes are reduced in the same proportion, to keep the government's budget balanced, majority voting yields a rate of environmental taxation that is lower than the optimal (Pigouvian) level. (iii) To mitigate this negative bias, the government reduces wage taxes by a higher proportion than capital income taxes. (iv) The final outcome will either be the Pigouvian tax or else all reductions will be given in wage taxes. This depends on individuals' preferences for the polluting good as well as wage and capital income distributions.     

Capital Gains Taxes and Asset Prices: Capitalization or Lock‐in?

This paper demonstrates that the equilibrium impact of capital gains taxes reflects both the capitalization effect (i.e., capital gains taxes decrease demand) and the lock‐in effect (i.e., capital gains taxes decrease supply). Depending on time periods and stock characteristics, either effect may dominate. Using the Taxpayer Relief Act of 1997 as our event, we find evidence supporting a dominant capitalization effect in the week following news that sharply increased the probability of a reduction in the capital gains tax rate and a dominant lock‐in effect in the week after the rate reduction became effective.     

Can Capital Income Taxes Survive in Open Economies?

Optimal-tax theory forecasts that small open economies should not tax capital income. Yet, countries do tax capital income. Why the inconsistency? This paper shows that use of the double-taxation convention, whereby governments credit taxes paid abroad against domestic taxes, helps explain this inconsistency. In particular, capital income will be taxed if a dominant capital exporter acts as a Stackelberg leader when setting its tax policy. Due to the convention, other countries will then tax capital imports, making it attractive for the dominant capital exporter to tax capital income. Without a dominant capital exporter, however, the model still forecasts no capital-income taxes.     

破解中国制造业产能过剩的新路径:外资开放政策的视角

产能过剩已经成为困扰中国经济可持续增长的深层次难题,本文以中国2002年外资管制放松作为准自然实验,采用倍差法系统研究外资开放政策对制造业产能利用率的影响及传导机制。研究发现,外资开放有效提升了同行业内资企业的产能利用率,生产效率、出口扩张和对外直接投资是外资开放影响内资企业产能利用率的重要渠道。外资开放对民营企业、一般贸易企业、吸收能力强的企业以及沿海地区企业产能利用率的提升效应更大,并且地区制度环境增强了外资开放的产能利用率提升效应。此外,内资企业除了获得行业内外资进入的水平溢出效应之外,还分别从上游和下游行业的外资进入中获得正向的前向关联与后向关联效应,进而显著提升了自身的产能利用率。最后,本文还进一步考察了外资开放政策对制造业总体产能利用率的影响,发现外资开放通过资源再配置渠道显著促进了制造业总体产能利用率的增长,进一步检验显示,外资开放一方面促进了市场份额从落后产能企业向相对优势产能企业的再配置,另一方面促进了落后产能企业的淘汰,进而提高了资源再配置效率并促进制造业总体产能利用率的提升。本文从外资开放政策视角探究了产能过剩问题,对新常态下破解产能过剩困境、实现“去产能”政策目标具有一定启示意义。     

金融发展、汇改最优次序与长期经济增长--基于118个经济体的面板模型的分析

本文构建由金融发展、资本开放、汇率制度与产出增长组成的理论模型,选取世界上118个经济体1972-2016年的宏观数据,综合运用动态面板、面板门槛与面板IV模型进行实证分析。本文得出主要结论为:第一,在汇率制度弹性对长期经济增长的边际影响中,金融发展水平呈显著为正的调节效应;第二,对于金融发展水平较高的国家,汇率制度弹性在资本项目开放度与长期经济增长之间存在显著正向的调节效应;第三,在金融发展水平较高时,对外贸易开放度在汇率制度弹性与长期经济增长之间存在显著为正的中介效应。借鉴历史发展经验,本文归纳出"先发展国内金融市场,再开放浮动汇率,最后加强资本开放"的汇改最优次序,为我国克服汇率制度改革难点、推进资本项目开放、维持经济基本面稳定增长提出合理化政策建议。     

Capital taxation and accumulation in a growing world economy with deficit finance

Prior analyses of the incidence of capital taxation have assumed that the government budget is balanced and changes in capital taxes affect either other taxes, transfers, or government expenditures. The general conclusion is that an increase in the capital tax rate will increase the gross-of-tax interest rate and decrease capital accumulation. This article examines the steady-state effects of capital taxation on the gross-of-tax interest rate and capital accumulation within a two-country model of overlapping generations, which allows capital taxation to directly affect government budget deficits. It is shown that, under the residence tax system, if the after-tax-interest rate is greater than the growth rate, an increase in the capital tax rate willdecrease the gross interest rate andincrease the capital-labor ratio. This result holds even under the territorial tax system, with some additional assumptions.     

论技术创新驱动经济发展的加速效应——兼论发展中国家中等收入陷阱产生的原因

在技术创新驱动经济发展的过程中,技术进步不仅直接通过提升资本要素的生产率水平来提升经济增长速度,而且也间接提升了资本积累的速度,由此将进一步提升经济增长速度,导致技术进步对经济增长速度的弹性大于1,形成了技术创新驱动经济发展的加速效用.当发展中国家剩余劳动力的转移依赖于资本积累的速度时,技术进步的速度还可以通过提升资本积累速度和剩余劳动力的转移速度来进一步提升经济增长速度,因此,发展中国家技术创新驱动经济发展加速效应更加明显.也正因为这一机理,发展中国家可能因为技术创新的速度过低导致经济发展速度过低从而陷入中等收入陷阱.
