我国个人所得税改革的误区及其突破

我国个人所得税改革存在一定的误区:税制改革的重点在于流转税、当前个税属于综合与分类相结合的税收模式、劳动所得作为个税的改革核心等。反思改革误区,我国个人所得税改革应实现三点突破:一是个税改革重点应由劳动所得转向资本所得,以股息和红利所得作为资本所得课税的改革核心,取消根据持有时间长短而差别计税的优惠政策;二是不断扩大个人所得综合征税的范围,逐步实现对资本所得的综合课税、以半二元模式作为我国综合与分类相结合的个税改革模式;三是缓步实现对个人所得税的"增税"调整,促进我国税制结构向"双主体"模式合理过渡。     

Climate Change Policies and Tax Recycling Schemes: Simulations with a Dynamic General Equilibrium Model of the Italian Economy

A dynamic general equilibrium model of the Italian economy is used to assess the impact of carbon taxation (or auctioned carbon permits), where additional revenue is used to cut either existing taxes on labor or on capital income. Simulation results do not support the existence of the so-called "double dividend" when labor taxes are reduced, whereas lower tax rates on capital have mild positive effects on growth and welfare, with progressivity properties on income distribution. These findings hinge on the assumptions of open economy, given world interest rate, and capital mobility.     

The winners and losers of tax reform: An assessment under financial integration

I quantify the macroeconomic and redistributive effects of the unilateral elimination of the capital income tax in a two-country, heterogeneous-agent incomplete markets model with progressive labor income taxes. Home, by implementing the reform, induces government responses where labor income is taxed in Home and mostly subsidized in Foreign. In addition, post-reform price dynamics reduce Home’s wealth and suppress households’ ability to do consumption smoothing, with negative effects on the majority—particularly on the poor. In turn, Foreign accumulates wealth, and price movements work particularly in favor of the poor. As a result, a large majority in Home prefers the status quo whereas Foreign supports the reform unanimously. These findings are robust to alternative scenarios where (i) the borrowing constraints are relaxed, (ii) both countries jointly eliminate capital income taxes, (iii) foreign interest income is taxed, and (iv) Home capital income tax is reduced from 40% to 35%.     

个人所得税纳税筹划的必要性与可行性

要合理避税,就必须对个人纳税进行筹划。本文对个人所得税的相关规定和个人所得税筹划现状进行研究,分析了个人所得税筹划的必要性,从最大限度给员工交纳住房公积金或社会保险费、发放通评补贴分种收入、通过集体福利分流收入、工资薪金与劳务报酬转化、单独列支项目、某些单位采用年薪制等6个方面提出了工资薪金个人所得税纳税筹划的措施;从最大限度将一些收入转化为费用列支、适时少计费用、将资本性支出转为收益性支出、采用拆借方法、采用融资租赁方式等5个方面提出了个体工商户个人所得税纳税筹划的措施。     

Factor substitution and taxation in a finance constrained economy

In this paper, we examine the effects of constant-rate factor taxation on macroeconomic stability in the Woodford (1986) model. Our focus is on how the degree of factor substitution, as measured by the elasticity of factor substitution (EOS) in production, affects different balanced-budget tax rules. Analytically, we show that indeterminacy can occur under capital income taxation only when the EOS is very low, whereas indeterminacy under labor income taxation is not subject to the EOS restriction. This finding is robust when we tax all of the factor incomes with equal rates. Thus, in terms of macroeconomic stability, taxing capital income is preferred to taxing labor income.     

Taxes, Federal Grants, Local Public Spending, and Growth

In a dynamic model with both private and local public capital accumulation, this paper examines how federal and local income taxes, local consumption tax, and federal matching grants for local public consumption and local public investment affect the long-run equilibrium (equilibria) of private consumption, private capital accumulation, local public consumption, and local public capital stock.     

Tax Regimes and Capital Gains Realizations

This paper contrasts the individual capital gains realization behavior between progressive and proportional tax regimes. Using a longitudinal panel of over 288,000 individuals in Sweden, I exploit the 1991 tax reform in Sweden that changed progressive capital gains tax rates ranging from 12% to 80% to a proportional tax rate of 30%. Using the proportional tax system to control for non-tax reasons to realize capital gains, I show that individuals are highly responsive to capital gains tax incentives created by temporary income changes under a progressive capital gains tax. More specifically, I find that individuals with temporary negative (positive) income changes sell (hold) shares that they would hold (sell) in the absence of temporary tax incentives. Further, I show that high-income individuals are more tax sensitive than low-income individuals. This result indicates that low-income individuals facing temporary negative income changes could trade predominantly for non-tax reasons.     

Health insurance reform: The impact of a Medicare buy-in

The steady-state general equilibrium and welfare consequences of a Medicare buy-in program, optional for those aged 55–64, is evaluated in a calibrated life-cycle economy with incomplete markets. Incomplete markets and adverse selection create a potential welfare improving role for health insurance reform. We find that adverse selection eliminates any market for a Medicare buy-in if it is offered as an unsubsidized option to individual private health insurance. The subsidy needed to bring the number of uninsured to less than 5 percent of the target population could be financed by an increase in the labor income tax rate of just 0.03–0.18 percent depending on how the program is implemented.     

NIT picking: The macroeconomic effects of a Negative Income Tax

I study a revenue-neutral reform of the U.S. income tax and welfare system that involves the adoption of a Negative Income Tax (NIT). The reform is undertaken in a life-cycle economy with individual heterogeneity and uninsurable idiosyncratic labor risk. The optimal NIT consists of a 22% rate and a transfer equivalent to 11% of per-capita GDP. The ex-ante average welfare gain is a 2.1% annual increase of individual consumption. I show that a NIT outperforms a flat tax reform (income tax plus deduction) by a considerable margin. The key consequence of the reform is that high-productivity agents increase their relative importance in the labor supply at the expense of low-productivity agents.     

Factor taxation and labor supply in a dynamic one-sector growth model

This paper studies a class of AK-type growth models with factor income taxes, public capital stock and labor–leisure trade offs. While a higher capital tax rate reduces economic growth in the short run, the long-term growth effect is ambiguous and remains ambiguous even if the level of tax rate is larger than the degree of government externality. A higher labor income tax rate has ambiguous growth effects both in the short and long runs. However, if the intertemporal elasticity of substitution for labor supply is sufficiently small, a higher labor tax rate always lowers economic growth in the long run, despite the existence of productive government taxation.     

DESIRABILITY AND SEQUENCE OF LIBERALIZATION AND STRUCTURAL REFORM POLICIES IN A MODEL WITH INFORMAL SECTOR

The paper develops a three-sector general equilibrium model with informal sector and examines the welfare effects of liberalization and structural reform in the presence of labor and capital market distortions. It attempts to determine a credible sequence of reforms that may be the most welfare-enhancing, since implementation of reforms in all the markets at a single stage may be neither feasible nor optimal. Foreign capital is welfare-improving only in the presence of labor market distortion, while welfare deteriorates if the capital market is distorted. While tariff and capital market reforms may be welfare-enhancing in the absence of labor market distortion, labor market reform may intensify the formal-informal wage gap and have a worsening effect on welfare in the presence of tariff distortion and capital market imperfection. One of the plausible sequences of reforms may be to initially undertake tariff reform followed by capital and labor market reforms, respectively.     

On the theory of interregional tax incidence

The state of factor income distribution prevailing in a local jurisdiction may be greatly influenced by the change in tax policies carried out by some other local jurisdictions through the market mechanism. The theory of interregional tax incidence is concerned with the problem of interactive distributional effects among local jurisdictions when each local government executes independently tax policies. This paper develops a new method of conducting a comparative static analysis on the current issue by making use of a general equilibrium model of interregional tax incidence characterized by the assumption that labor is perfectly immobile between different jurisdictions.     

Innovation dynamics and fiscal policy: Implications for growth,asset prices,and welfare

We study the equilibrium implications of different fiscal policies on macroeconomic quantities and welfare by utilizing an endogenous growth model that matches asset pricing data well. The fiscal instruments of interest are (i) subsidies to R&D expenditure, consumption and capital investment, and (ii) cuts in labor and corporate tax rates. Our equilibrium analysis provides new insights on the interplay of innovation dynamics and fiscal policy. Importantly, we find growth and welfare to be inversely related when changing R&D subsidies. However, this depends on how well the model reproduces asset pricing dynamics. Moreover, only subsidies to capital investments and cuts in the corporate tax rate have the potential to increase both growth and welfare.     

An Applied General Equilibrium Model to Assess the Impact of National Tax Changes on a Regional Economy

This paper presents two versions of an applied general equilibrium model for the regional economy of Andalusia, Spain, that differ in the closure rule adopted to describe the behavior of the public sector. We use the model with to analyze the impact that the reform of the personal income tax (Act 40/98) implemented in Spain as a whole would have had on the Andalusian region in particular. The model is of the neoclassical variety and includes not only the productive sectors of the economy but also the foreign sector and the government, which are usually absent from theoretical general equilibrium models. Both versions of the model are calibrated by using a Social Accounting Matrix of Andalusia for 1995. The analysis shows that the reform is not self-financing, not even partially, despite governmental claims. It also indicates that there is a positive but smaller than anticipated economic stimulus. In welfare terms, we find that the category of Urban Salaried consumers is the one that benefits the most in real income terms.

Agricultural Trade Liberalization in a Computable General Equilibrium Framework for the Philippines

A bi-regional and multi-market computable general equilibrium model that focuses on the agricultural sector of the Philippines' economy in 1987 is constructed. This paper presents the basic structure of the model and carries out some cost-benefit analyses to assess the impact of alternative trade reform policies on the economy. It is found that various liberalization policies can produce large benefits, but any single policy implemented separately may incur intolerable costs. However, a combination of trade liberalization and currency devaluation, coupled with target income support and income tax reform, can achieve balanced results that are beneficial to the economy without worsening income distribution and food consumption of the poor.     

Proposals to Tax Life Insurance Savings as Personal Income

A bstract . Proposals to tax the realized net increment built up in life insurance policies amount to suggestions that we tax rewards to suppliers of capital. As tax policy it would tend to discourage capital accumulation. Many types of income and of capital gains are not taxed as a matter of social policy. Taxing the "inside buildup" would obstruct the building up of a capital base for the family and the economy. Economists recognize that there are alternatives, e.g. , a consumption based tax. In a time of great need for capital, a time of capital shortage, this tax policy would be retrogressive.     

Tax rate uncertainty,labor supply and saving in a nonexpected utility maximizing model

The effects of uncertainty in rate of return tax rate, wage income tax rate and a comprehensive tax rate which affects both return to saving and wage income are analyzed in a nonexpected utility maximizing framework of Selden (1978). We consider a two period model where the agent works and saves. The effect of rate of return tax rate uncertainty on labor supply and saving critically depends on the magnitude of the elasticity of intertemporal substitution. A wage income tax rate uncertainty on the other hand unambiguously raises work effort while its effect on saving again depends on the magnitude of the intertemporal substitution elasticity. For empirically plausible magnitudes of the intertemporal substitution elasticity, saving responds positively to wage income tax rate risk. The effect of a comprehensive tax rate uncertainty on labor supply and saving, however, depends solely on the magnitude of the elasticity of intertemporal substitution.     

Estimating DSGE models using seasonally adjusted and unadjusted data

This paper evaluates the common practice of estimating dynamic stochastic general equilibrium (DSGE) models using seasonally adjusted data. The simulation experiment shows that the practice leads to sizable distortions in estimated parameters. This is because the effects of seasonality, which are magnified by the model’s capital accumulation and labor market frictions, are not restricted to the so-called seasonal frequencies but instead are propagated across the entire frequency domain.
