Optimal Tax Theory: The Journey from the Negative Income Tax to the Earned Income Tax Credit

What lessons do we learn from optimal tax theory for the design of income redistribution programs? I modify a standard model of optimal nonlinear income taxation with discrete types to consider differences in both earning ability and the disutility of effort. This gives a role for “workfare” in the optimal tax policy. The existence of screening mechanisms can play a role in explaining non‐participation in cash and in‐kind redistribution programs, including Progresa‐Oportunidades, Lifeline Telephone subsidies, and the Special Supplemental Nutrition Program for Women, Infants, and Children (WIC). Stigma can increase efficiency of a redistribution program by discouraging participation by individuals near the eligibility thresholds. The Family Assistance Program proposed in the early 1970s lacked adequate stigma for nonworkers, which contributed to a lack of political support. In contrast, the current Earned Income Tax Credit (EITC) provides greater benefits to workers than to nonworkers. Thus the EITC does not require any stigma to screen out individuals who do not work from obtaining benefits. Reasons for separate income support programs for nonworkers and for workers are discussed.     

The Timing of Redistribution

We investigate whether late redistribution programs that can be targeted toward low income families, but that may distort savings decisions, can “dominate” early redistribution programs that cannot be targeted as a result of information constraints. We use simple two‐period overlapping generations models with heterogeneous agents under six policy regimes: a model calibrated to the U.S. economy (benchmark), two early redistribution (lump sum) regimes, two (targeted) late redistribution regimes, and finally a model without taxes and redistribution. Redistribution programs are financed by a labor tax on the young generation and a capital tax on the old generation. We argue that if the programs are small in size, late redistribution can dominate early redistribution in terms of welfare but not in terms of real output. Better targeting of low income households cannot completely offset savings distortions. In addition, we find that the optimal transfer and tax policy implies a capital tax of 100% and transfers exclusively to the young generation.     

我国个人所得税的再分配效应及国际比较

个人所得税是调节收入分配差距的重要手段之一。文章认为：整个考察期间,除2006年外,我国个人所得税制发挥了正向、且进一步加强的再分配效应。但与其它国家相比,其调节效果非常有限。主要原因在于：我国个人所得税没有发挥主体地位,在制度设计上存在严重缺陷,而且在税收征管上也存在许多漏洞。因此,为了更好地发挥其应有的再分配效应,全面的个人所得税制改革迫在眉睫。     

免征农业税以来经济欠发达地区农村所面临的问题与对策

随着农村税费改革的不断推进,在全国范围内免征农业税是"以工促农、以城带乡"的重要转折,也是突破"黄宗羲定律"的关键。结合新时期中央关于切实加强农业基础建设进一步促进农业发展农民增收的若干意见,文章重新梳理了免征农业税的重大现实意义与历史意义分析了免征农业税以来经济欠发达地区农村发展所面临的新问题并提出了相应的对策建议。     

Capitalization of local government grants on land values: Evidence from Tokyo metropolitan area,Japan

This study investigates the capitalization effect of intergovernmental fiscal transfers from central to local governments on land prices. Using a drop in the size number of fiscal transfers following fiscal reform in the early 2000 s, this study examines the extent to which unconditional fiscal transfers to municipalities in the Tokyo metropolitan area are attributed to land prices. The result shows that the decline in the transfer has decreased the land prices in the municipalities. Furthermore, reducing one unit in the per capita grant reduced the value of housing area per capita by one or more units, even if the real discount rate was assumed to be as low as 2%. Therefore, the fiscal transfer reform more negatively affects the benefits of residing in a municipality in the area than the reduction amount in the transfer.     

Economic growth and income inequality in the Asia-Pacific region: A comparative study of China,Japan, South Korea,and the United States

This paper builds an inequality-growth-redistribution nexus, and applies the Engle–Granger two-step ECM approach to estimate the long-run and short-run relationships between inequality and growth for four economies: China, Japan, South Korea, and the United States. Our estimation results support the S-shaped curve hypothesis relating GDP per capita to inequality with different starting points for the four economies. For the reverse relationship, we find a positive causal relationship for China, Japan, and the United States, indicating that increased income inequality spurred economic growth. In addition, we find mixed results on the effect of trade openness on inequality and growth. Trade openness reduced inequality in the United States and Japan, worsened it in China and had no significant effect in South Korea. In the inequality-GDP per capita relationship, exports provided an impetus to economic growth for Japan. As for redistribution, although fiscal redistributive measures reduced inequality in Japan, they played no major role in the other three countries. With regard to the inequality-GDP per capita relationship, all countries except for China show a negative effect of fiscal redistribution on GDP per capita.     

Deficit Estimation and Welfare Effects after the 1994 Fiscal Reform in China： Evidence from the County Level

Using simple statistical analysis of count-level budgetary data from across all of China＇s counties, the present paper examines whether the post-1994 fiscal decentralization has affected redistribution at the count-level. The new fiscal system has been less able to narrow inter-county dispersion in ftscal imbalances than the old one, even after taking intergovernmental transfer payments into account. Although with the post-1994 system there has been a modest increase in per capita welfare spending in all counties on average, much of the new-found fiscal resources have been spent on salary and administrative expenses rather than spending on public goods. Therefore, it is imperative that the reform of China＇s tax system is intensified.     

关于我国个人所得税制度的思考

我国的个人所得税制度自1980年建立以来,在调节收入分配,缩小贫富差距,增加财政收入方面起到了积极的作用。随着我国经济的快速发展,我国个人所得税制度在税制模式、课税标准、税率、起征点方面日益暴露出其存在的问题。文章认为,建立分类和综合相结合的混合税制,依据物价指数和国家经济形势的发展适时调整费用扣除标准和个税起征点,适当降低边际税率、调整级距是当前个人所得税制度改革需要研究的问题。     

The potential impact of abolishing company tax in Ciskei

The purpose of this paper is to examine the likely effect of the abolition of company tax on the Ciskeian economy. After considering the case for and against a corporate tax exemption, the issues involved are analysed on two levels. Using aggregate data, drawn from available census data, we find that most firms seem likely either to prefer the existing package of industrial concessions to the tax holiday, or to be indifferent to either option. Similarly, a recent survey of manufacturing enterprises in Ciskei indicated that the majority would prefer the incentive package. Firms that might be attracted by the tax‐free option are likely to be relatively profitable, subsidiaries of multinational companies, and enjoying a higher turnover per worker than firms opting for the incentive package.     

Supplying Slot Machines to the Poor

As gambling becomes increasingly accessible worldwide, governments face an important policy question: how should they exploit the industry's growth to raise tax revenue while protecting individuals from the detrimental effects of gambling? Using data on slot machines from the largest per capita gambling market in the world, Australia, we estimate a structural oligopoly model to (i) quantify firms' incentives to make gambling accessible among socioeconomically disadvantaged groups and (ii) evaluate the effect of government policy (tax levies, supply caps, and venue smoking bans) on the distribution of slot machine supply, tax revenue, and problem gambling prevalence.
