生态赤字税：理论与实证研究框架

文章基于生态足迹核算方法和生态服务价值理论所确定的价格体系,在核算生态赤字及其价值并提出其价值补偿的环境税方案的基础上,将生态占用作为一种要素投入,构建绿色社会核算矩阵和环境税 CGE 模型,通过数值模拟比较分析了在5%、10%和30%的补偿强度下税收方案的环境效应、就业效应、增长效应、分配效应和贸易效应。模拟结果表明：(1)生态赤字税方案具有减少生态占用和增加就业的双重红利效应;(2)各部门的总产出和中间投入总体上下降,但名义 GDP 增长,绿色 GDP 增幅更大,而实际 GDP 则下降,表明税收政策会造成价格指数一定程度的上升;(3)政府税收收入因生态赤字补偿额度较大而增长较快,且增速高于劳动和资本要素报酬的增长,但居民收入和企业收入比重略有下降。基于我国资源与环境等税收在总税收中的比重,以及 OECD 国家的税制结构和变化趋势,文章最后建议生态赤字税的补偿性税率应低于5%。     

两税合并、税收筹划与盈余管理方式选择

文章以2007年的两税合并为背景,研究上市公司出于税收筹划的目的如何选择盈余管理方式。研究发现,税率下降公司由于税率下降幅度较大,税收筹划收益较高,因此进行了显著向下的应计盈余管理,而没有选择真实盈余管理方式;而税率上升公司则由于存在5年的过渡期,税收筹划收益较低,因此既没有进行显著的应计盈余管理,也没有进行显著的真实盈余管理。这意味着上市公司在进行税收筹划时会综合权衡各种避税方式的成本收益,进而选择最合适的避税方式。政府部门在制定税收政策时必须预先考虑企业可能的税收筹划策略,以达到预期的政策效果。     

Attracting private investment: Tax reduction,investment subsidy,or both?

This paper uses a real-option model to examine the net benefit to a government from using tax cut and/or investment subsidy as incentives to induce immediate investment. Although earlier papers generally concluded that investment subsidy dominates tax cut, it is observed that many governments use a combination of subsidy and tax cut. We show that, when the government uses a different discount rate from private firms, and when it has to borrow money to provide an investment subsidy, it is possible to get an internal optimum; that is, it might be optimal for the government to provide an investment subsidy as well as charge a positive tax rate on the profits from the project. Thus, we provide an explanation for the puzzling fact that many governments provide an investment subsidy to a firm while simultaneously taxing its profits.     

环境保护税对经济和碳排放影响研究——以江苏省为例

环境保护税的征收,有效减少了污染物排放,同时也会对经济和碳排放产生一定影响。通过构建包含环境保护税模块的CGE模型和江苏省2018年环境社会核算矩阵,模拟分析不同环境保护税税率对江苏省经济发展和碳排放的影响。研究发现:(1)征收环境保护税会给江苏省经济带来负面影响,但影响程度较小,当征收税率上升时,江苏省GDP、出口、省际调出等会下降,而居民和地方政府收入几乎没有变化。(2)环境保护税税率上升时,不仅会增加环境保护税收入,还会减少江苏省碳排放水平。(3)对于大多数行业,环境保护税税率上升会造成行业产出下降,但是对于污染物排放强度较低的行业,行业产出会上升,碳排放会增加。(4)为了更好地完成碳减排目标,建议江苏省可以适度增加环境保护税税率或加征碳税,对于污染物排放浓度较低的行业,可以采取补贴措施鼓励发展;对于污染物排放强度较高的行业,要推动转型升级,降低排放强度。     

Two-part tariffs in the online gaming industry: The role of creative destruction and network externalities

Playing computer games online is a fast growing, billion dollar industry which has received little academic attention. The industry exhibits a number of interesting economic features. The industry structure is determined by creative destruction as in Aghion and Howitt (1992) [Aghion, P., Howitt, P. 1992. A model of growth through creative destruction, Econometrica, 60(2), 323–351], with game makers experiencing market power within a genre until the game is superceded. Furthermore, the attractiveness of playing a game online depends on the existence of opponents (positive network externalities) while technical and reputational problems eventually arise (negative network externalities). We model the choice of two-part tariffs by a monopolist under creative destruction and network externalities and derive conditions for the multiple equilibria which currently exist in the industry.     

Tax Havens,Growth, and Welfare

This paper develops an endogenous growth model featuring tax havens, and uses it to examine how the existence of tax havens affects the economic growth rate and social welfare in high‐tax countries. We show that the presence of tax havens generates two conflicting channels in determining the growth effect. First, the public investment effect states that tax havens may erode tax revenues and in turn decrease the government's infrastructure expenditure, thereby reducing growth. Second, the tax planning effect of tax havens reduces marginal cost of capital and hence encourages capital accumulation so as to spur economic growth. The overall growth effect is ambiguous and is determined by the extent of these two effects. The welfare analysis shows that tax havens are more likely to be welfare‐enhancing if the government expenditure share in production is low, or the initial income tax rate is high. Moreover, the welfare‐maximizing income tax rate is lower than the growth‐maximizing income tax rate if tax havens are present.     

生态赤字税：绿色发展与税制改革*

本文在量化生态占用并评估生态价值基础上,提出运用税收实现超额生态占用价值补偿的税收方案,也称生态赤字税。根据税制生态化的改革思路,本文运用CGE模型分析了征收生态赤字税和降低所得税的政策效应。本文研究发现：(1)在各税收方案中,生态赤字减少,就业增加,支持双重红利假说,全行业中间投入减少相对总产出减少更大,名义GDP保持增长;(2)实际GDP在生态赤字税基础上仅减少企业所得税的方案中下降,同时减少个人所得税则能实现增长,此时减税额低于生态赤字税收入;(3)在开征生态赤字税同时,降低个人所得税在保持经济增长方面较好,降低企业所得税在减少生态赤字方面较好,但降低企业所得税所减少的生态赤字价值低于降低个人所得税时劳动和资本增加值的提高。本文建议在完善生态占用核算基础上开征生态赤字税,并减轻所得税,促进经济增长由资源环境消耗转向劳动和资本投入的绿色发展。     

The (Non‐)Equivalence of Input and Output Taxes Under Monopoly

The author argues that a government taxing a polluting monopoly by means of levies on output and inputs can implement the first‐best allocation through a continuum of tax profiles. Using this degree of freedom in the tax system, the government is, in general, able to transfer income from the firm to the public sector, so that the additional tax rate acts as a non‐distorting tax on profits. This transfer – and therefore public revenue – is the higher, the lower (higher) the input taxes are, and correspondingly the higher (lower) the output tax is, provided that the production function exhibits decreasing (increasing) returns to scale.     

Tax progressivity, income distribution and tax non-compliance

This article examines the determinants of tax non-compliance when we recognise the existence of an imperfectly competitive “tax advice” industry supplying schemes which help taxpayers reduce their tax liability. We apply a traditional industrial organisation framework to model the behaviour of this industry. This tells us that an important factor determining the equilibrium price and hence, the level of non-compliance, is the convexity of the demand schedule. We show that in this context, this convexity is affected by the distribution of pre-tax income, the progressivity of the tax-schedule and the way in which monitoring and penalties vary with income. It is shown that lower pre-tax income inequality as well as a less progressive tax code may cause more tax minimisation activities. Therefore, the frequently advocated policy of reducing the highest tax rate may fail as a policy directed at improving tax discipline. One way of offsetting the possible harm to tax compliance from a less progressive tax could be an adjustment of the penalty and monitoring functions.     

R&D and Absorptive Capacity: Theory and Empirical Evidence*

This paper presents a single unified framework that integrates the theoretical literature on Schumpeterian endogenous growth and major strands of the empirical literature on R&D, productivity growth and productivity convergence. Starting from a structural model of endogenous growth following Aghion and Howitt (1992, 1998) , we provide microeconomic foundations for the reduced‐form equations for total factor productivity (TFP) growth frequently estimated empirically using industry‐level data. R&D affects both innovation and the assimilation of others’ discoveries (“absorptive capacity”). Long‐run cross‐country differences in productivity emerge endogenously, and the analysis implies that many existing studies underestimate R&D's social rate of return by neglecting absorptive capacity.     

Supply-Side Economics of Germany's Year 2000 Tax Reform: A Quantitative Assessment

Abstract. The paper provides an assessment of supply‐side economics following Germany's year 2000 tax reform. Investigated are a corporate tax cut, deteriorating depreciation allowances and imputation rules, and a private income tax cut. For this purpose, a neoclassical growth model is augmented by various fiscal policy parameters and endogenous corporate finance and calibrated with German data. The model is used to evaluate consequences of Germany's tax reform on production, firm finance and leverage, investment, consumption and welfare of a representative household.     

The impact of the Indonesian income tax reform: A CGE analysis

This study evaluates the impacts of Indonesia's recent income tax reforms on key macroeconomic variables, as well as the impacts on poverty and income distribution. It was found that the reductions in personal income tax and corporate income tax increase economic growth under a balanced budget assumption. The policy reforms also lead to a small reduction in the incidence of poverty. However, the policies also lead to an increase in income inequality because the tax cut is more beneficial to households in the highest income categories. It is recommended that future tax cuts should target the urban and rural poor.     

Tax bases,tax rates and the elasticity of reported income

Tax reforms usually change both tax rates and tax bases. Using a panel of income tax returns spanning the two major U.S. tax reforms of the 1980s and a number of smaller tax law changes, I find that the elasticity of income reported on personal income tax returns depends on the available deductions. This highlights that this key behavioral elasticity is not an immutable parameter but rather that it can be to some extent controlled by policy makers. One implication is that base broadening reduces the marginal efficiency cost of taxation. The results are very similar for all income categories indicating that the rich are more responsive to tax rates because tax rules that apply to them are different (their tax base is narrower). The point estimates indicate that the Tax Reform Act of 1986 reduced the marginal cost of collecting a dollar of tax revenue, with roughly half of this reduction due to the base broadening and the other half due to the tax rate reduction. As a by-product, the analysis in this paper offers a reconciliation of disparate estimates obtained by previous studies of the tax responsiveness of income.     

Macroeconomic Implications of Changes in Corporate Tax Rates: A Review

Many countries have initiated structural reforms in corporate income tax (CIT) to attract investment and promote growth. There has been a continuous decline in CIT rates worldwide. It is expected that cuts in CIT rates may increase after-tax profits and encourage investment. A change in the CIT rate may also be shifted backward (by changing salaries and wages) and/or forward (by changing product prices). These are theoretical possibilities and may not have support from empirical evidence. In this paper we review empirical studies to assess the impact of CIT rate changes on the economy.     

Job creators,job creation,and the tax code

This paper considers the role of the tax code in determining income dispersion and vacancy creation. A “span‐of‐control” model is embedded into a search and matching environment. A cut to the tax on profits in isolation improves job creation and reduces before‐tax income inequality. The impact of a budget‐balancing increase in the wage tax depends on the bargaining power of firms. When it is high, firms pick up the lion's share of the tax burden. The tax acts like a barrier to entry: it benefits large firms at the expense of marginal ones. Net effects are an increase in unemployment and before‐tax income dispersion. Low firm bargaining power means workers pick up more of the tax burden. It acts like a subsidy to entrepreneurship reinforcing the impact of the profit tax reduction. Taxes on the returns to capital leave everyone worse off.     

Effect of the Tax System ON R&D Intensity,Growth, Wages and Consumption Share

We propose a general equilibrium knowledge‐driven (semi‐)endogenous‐growth model with horizontal R&D, which is extended to consider two types of labour, skilled and unskilled, and exogenous government expenditure, financed through taxes on financial assets and on labour income, to analyse the implications of the tax system on R&D intensity, economic growth, wage inequality and consumption share in the output. In particular, we show that: (i) taxes have negative influence in the consumption share, being higher the marginal effect of the labour‐income tax; (ii) for any given government expenditure share, an increase (a decrease) in financial‐assets tax decreases (increases) the labour‐income tax; (iii) only the financial‐assets tax affects negatively the R&D intensity and the skill‐premium; thus, to reduce the skill‐premium the financial‐assets tax must increase; (iv) ignoring the effect on wage inequality and on R&D intensity, taxes are substitutes.     

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.     

Tax decentralization,labour productivity,and employment in OECD countries

Tax decentralization should improve the efficiency of local governments and ultimately boost output growth. However, the empirical evidence is mixed. Decomposing output growth into labour productivity and employment growth, we show that the ultimate effect of fiscal decentralization on growth depends on which factor prevails, thus rendering the direct estimation of tax decentralization on growth ambiguous. Using an instrumental variable approach, with instruments based on institutional similarities and geographic distance, the empirical analysis on a sample of 20 OECD countries shows that the positive and significant effect of tax decentralization on the employment growth rate is offset by the reduction of labour productivity growth, resulting in the absence of any statistically significant effect on output growth.     

Fiscal policies, environmental pollution and economic growth

This paper develops a model of endogenous economic growth with special consideration to the role of productive public expenditure and environmental pollution; and analyses the properties of optimal fiscal policy in the steady state growth equilibrium. We consider the level of consumption as the source of pollution. Government allocates its tax revenue between pollution abatement expenditure and productive public expenditure. Optimum ratio of productive public expenditure to national income is equal to the competitive output share of the public input, when productive public expenditure is depicted as tax revenue minus abatement expenditure. However, the proportional income tax rate exceeds the competitive output share of the public input. There is no conflict between the social welfare maximizing solution and the growth rate maximizing solution in the steady state growth equilibrium. The unique steady state growth equilibrium appears to be a saddle-point when the growth rate is above a critical level and the steady state equilibrium growth rate in the market economy is not necessarily lower than the socially efficient growth rate.     

Tax compliance and firm response to electronic sales monitoring

This paper analyzes how firms respond to an Internet of Things technology that reduces significantly the tax authorities' marginal cost of monitoring firm activity. More precisely, we analyze how mandating every restaurant of a single Canadian province to have sales recording modules (SRMs) affects restaurant sales, expenses and profits. We estimate that SRMs increase reported sales by 5.8% to 9.8% on average and that this increase is almost completely offset by an equal increase in expenses, including wages. As a result, the firms' taxable income remains mostly unchanged. Our results suggest that sales tax remittance enforcement at the firm level spills over to other firm stakeholders, such as employees and suppliers. Overall, the one-time cost of the device needed to monitor sales more efficiently is small compared with the recurring benefits for tax authorities.
