Are contributions of time and money substitutes or complements?

This article empirically investigates the relationship between donations of time and money using Canadian tax policy reforms that changed the tax price of charitable donations. The 1988 reform where a charitable tax deduction was converted to a credit and the 2000 reform in provincial income taxes provide tax price variations plausibly exogenous to individuals’ unobserved heterogeneity. Our estimates on cross-price effects imply that individuals make more time donations as the tax price of charitable donations increases and hence money and time donations are substitutes, as some theories would imply. This contrasts with earlier findings using cross-sectional data.     

促进科技创新的税收激励政策——英美等国的主要经验及其启示

创新体系理论对税收激励政策有重要的影响。创新的税收激励,特别是R&D税收抵扣政策,在发达国家有效地保留和吸引了R&D投资。那些在税收激励上最慷慨的国家均是吸引外来R&D投资最多的国家。R&D抵扣直接利益是刺激R&D投入。美国R&D税收抵扣有3种方案,即传统抵扣、选择性增量研究抵扣(AIRC)和选择性简化抵扣(ASC);英国主要是增强型扣除。政策设计时要参考多种因素。我国施行R&D税收抵扣政策,要研究制定统一的、供税收目的的R&D支出标准,出台具体的实施办法,并注意政策的可操作性、可预测性、一致性和稳定性。

Testing for the Ratchet Effect in the R&D Tax Credit

Many countries have implemented the R&D tax credit to encourage firms’ R&D spending. The design of the tax credit is important for its effectiveness. Some countries such as Korea, Taiwan, Japan, France and the US have employed an incremental R&D tax credit system. The US case that made a major change in its design from the moving average base to the fixed base in calculating the credit provides us with a natural experiment to measure the effectiveness of the tax credit from the perspective of the ratchet effect. By applying an endogenous switching regression model to US manufacturing firm data, we attempt to measure the ratchet effect of R&D credit on firms’ R&D investment. According to the empirical results, the R&D tax credit policy has been effective with the price elasticity, –1.818, for the qualified firms, and the re-design of R&D credit improved the positive impact of R&D credit. This provides some policy implication for those countries that adopted an incremental credit system. In addition, our result suggests the existence of selectivity bias in the previous literature.     

弹性分成：分税制的契约与影响

本文从契约角度分析分税制的性质,并用统一的框架解释了分税制的正反两方面作用。研究认为：中国的分税制本质上是一个弹性的分成合同系统。它是中央政府与地方政府关于剩余分配的各种子契约的组合。这些子契约可归为四种基本形式--工资合同、定额合同、分税合同和分成合同,并且它们之间具有很强的互补性,由此构成了一个富有弹性的分成合同系统。在信息不对称的条件下,这个激励系统能够激励地方政府发展经济,但是易扭曲地方政府行为,促使经济重复建设和粗放型增长模式的形成。     

Effects of tax benefits on the price elasticity of charitable contributions in South Korea

Using South Korean panel data from 2008 to 2019 and censored quantile regression method, this study calculates the effects of different tax incentives on charitable contributions. We observe price elasticity under two different tax-benefit systems in South Korea and find that, first, taxpayers tend to be more sensitive to tax incentives under a tax deduction system than a tax credit system. The price elasticity gap between a tax deduction and tax credit is approximately −2.3 to −1.0. Second, we show the existence of heterogeneity in taxpayers’ behaviour: the price elasticity of charitable contributions exhibits a convex shape, where more significant donors have lesser reactions to tax incentives. We further show that socioeconomic contexts, such as income, gender, marital status, and education, affect people's attitudes. In sum, the results are as expected: tax deductions work more efficiently than tax credits.     

税收政策与居民消费需求——基于结构效应视角的新思考

本文运用税收经济效应原理系统阐释所得税、商品税与财产税对居民消费需求的作用机制,在考察我国税制结构整体状况及其对居民消费需求负面影响的基础上,通过建立动态面板数据模型与采用GMM估计方法实证估计税收政策对居民消费需求的结构效应,结果发现：一方面,财产税挤入居民消费;另一方面,商品税和所得税均挤出居民消费需求,但开征利息税能够显著降低个人所得税对居民消费需求的抑制效应。基于理论分析与实证估计结果,本文认为,政府为了提高税收政策对居民消费需求调节的针对性与激励效果,应充分发挥税收政策的结构效应,积极推进与实行“有增有减”的新一轮税制改革,构建与扩大居民消费需求相协调的税制结构。     

The effects of vertical and horizontal incentives on local tax efforts: evidence from China

Tax effort is a measure of a government’s effort to collect taxes. This study explores what impacts both vertical and horizontal incentives have on local governments’ tax efforts in China. For consistency with the literature, we first include typical economic and institutional factors in our analysis. We find that the effects of economic factors on local tax efforts are significant, but the effects of institutional factors tend to be weak. Fiscal decentralization, as a vertical incentive, has a significantly positive effect on tax efforts at the provincial level. Meanwhile, fiscal interaction, as a horizontal incentive, is also taken into account in a spatial specification to explain tax competition among local governments. The results show that local tax effort in China also depends on the horizontal incentive. Hence, to improve local tax effort, the central government should let the locals have more autonomy in collecting taxes and evaluate local tax effort by referring to tax collection in adjacent provinces simultaneously.     

纳税信用评级结果披露与研发投入

以纳税信用评级披露作为一个天然外生冲击,并基于2013—2016年1214家A股上市公司的微观数据构造准自然实验,使用双重差分法系统评估纳税信用评级结果披露对上市公司研发投入的影响。结果发现:纳税信用评级结果披露显著增加了上市公司的研发投入。基于PSM-DID方法的估计结果与上述结论无明显差异。稳健性检验也表明上述结论的正确性。机制检验表明,纳税信用评级结果披露通过降低企业的融资约束,进而促进企业增加研发投入。此外,分样本回归发现纳税信用评级结果披露只能对中小型企业和民营企业的研发投入产生促进作用。     

Excise taxes,over-shifting,cross-elasticity,and tax revenue

This article examines cross-elasticity effects in excise taxation for markets characterized by monopolistic competition and over-shifting. Extending the constant elasticity demand model to consider cross-elasticity leads to notably different results regarding tax revenue maximization. With nonzero but weak cross-elasticity effects relative to the price elasticity, we derive a higher optimal tax-price ratio compared to prior research. With strong cross-elasticity, revenue can continually be increased by raising the excise tax. Overall, the study offers government greater incentive to use excise taxes to obtain revenue.     

THE IMPACT OF TAX PRICE CHANGES ON CHARITABLE CONTRIBUTIONS TO THE NEEDY

Eliminating or reducing the federal charitable deduction can have serious impacts on the level of charitable donations. Tax price elasticity estimates from a multivariate sample selection model indicate that changing the deduction to a 12% tax credit would have reduced individual donations in 2012 by 18.9% if applied to itemizing taxpayers and by 10.5% if extended to nonitemizers. Elimination of the deduction would have led to a 35% reduction in individual charitable donations. Even if coupled with cuts in marginal tax rates, eliminating the charitable deduction will still likely result in substantial reductions given the inelastic income elasticities of charitable donations. The estimates justify the ardent opposition of many in the nonprofit sector to the more radical proposals for changing the tax treatment of charitable contributions. (JEL D34, C34)     

The impact of taxes and wasteful government spending on giving

We examine how taxes impact charitable giving and how this relationship is affected by the degree of wasteful government spending. In our model, individuals make donations to charities knowing that the government collects a flat-rate tax on income (net of charitable donations) and redistributes part of the tax revenue. The rest of the tax revenue is wasted. The model predicts that a higher tax rate increases charitable donations. Surprisingly, the model shows that a higher degree of waste decreases donations (when the elasticity of marginal utility with respect to consumption is high enough). We test the model’s predictions using a laboratory experiment with actual donations to charities and find that the tax rate has an insignificant effect on giving. The degree of waste, however, has a large, negative and highly significant effect on giving.

Political Measures for Strategic Environmental Policy with External Effects

This paper investigates an environmental policy designed to reduce the emission of pollutants under uncertainty, with the agent problem as an optimal stopping problem. We first analyze the two cases in which there are one agent and two competing agents by following Ohyama and Tsujimura (2005). When we consider a model of strategic agents, we need to analyze the external economic effect that is peculiar to an agent’s environmental policy implementation. Then, to improve and resolve these external effects, we examine three alternative political measures, comprising an environmental subsidy, an environmental tax and an emission trading system. The results of the analysis indicate that the environmental subsidy and environmental tax promote environmental policy. However, they do not create an incentive to be the leader. On the other hand, an emissions trading system not only promotes environmental policy but also creates an incentive for leadership.This paper was previously circulated under the title “Political Measures for Strategic Environmental Policy with Induced Effects”.

Donations in a recursive dynamic model

Abstract.  This paper studies how donations respond to unexpected permanent changes in income and tax rates in a recursive dynamic model. The dynamic approach yields several interesting insights. If marginal tax rates are progressive, a permanent jump in a household's income increases its consumption and donations in the short run, but has no effect in the long run. The permanent income elasticity of current donations is likely to exceed one. If the marginal tax rate is flat, the jump in income raises consumption and donations in both the short and the long run. A permanent marginal tax rate cut raises consumption and donations in the long run if marginal tax rates are progressive, while it reduces donations in the short run if it has little direct impact on tax payments. If the marginal tax rate is flat, a tax cut has a positive effect on consumption in both the short and the long run, but has an ambiguous effect on donations.     

Does tax policy affect credit spreads? Evidence from the US and UK

This paper studies how exogenous tax changes affect credit market conditions in the US and UK. Using both structural VAR and structural factor-augmented VAR (FAVAR) model, we find that tax-policy shocks have significant effects on the credit spread. Specifically, the credit spread responds first positively and then negatively to an exogenous tax increase in the two countries. Moreover, the impulse responses of the credit spread to tax-policy shocks do not always accord well with the impulse responses of the output. This indicates that there are channels of tax policy transmission to the credit spread other than through its impact on the business cycle.     

构建我国纳税人诉讼制度的理论基础

纳税人诉讼制度是公民财政监督权的具体体现,是实现财政民主与财政法治的重要途径。文章逐次分析了纳税人诉讼制度的政治学、经济学以及法学基础,指出“税收契约”、“税收价格”和“．税收债权债务理论’’都是纳税人诉讼赖以建立的理论基础,而宪法中关于人民主权、财产权、监督权的规定是纳税人诉讼得以建立的直接依据。     

R & D税收激励有效性与影响因素

基于生产函数理论抽象出盈利能力和研发程度是R&D税收激励效应的两个关键因素,进而采用2012-2015年全国高新技术企业调查数据,分别检验了15%税率式优惠与研发加计扣除政策的有效性及其影响因素。实证结果表明：15%税率式优惠与加计扣除政策均能激励企业创新,而加计扣除激励效果显著优于15%税率式优惠;15%税率式优惠政策效应受企业盈利能力影响较大,而加计扣除政策受企业研发投入的作用较大;15%税率式优惠政策对高新制造业、服务业和文化产业创新激励效果不显著,而加计扣除对高新制造业和文化产业研发密集型行业创新具有显著的激励作用;15%税率式激励对成熟度较高企业创新具有较好的激励效应,而研发费用加计扣除政策对成熟度较低企业创新具有较强的促进作用。     

促进非政府组织发展的税收政策

利用税收政策促进非政府组织发展是世界各国的普遍做法,中国也不例外。然而中国针对非政府组织的税收政策还存在着税收政策有失公平、税式支出被滥用、纳税人公益性捐赠税前抵扣限制较多以及对民间非政府组织的歧视性税收待遇等问题。因此,需要对现行的税收政策进行调整,如把非政府组织分为＂公益性＂和＂互益性＂,实行不同的税收政策,开征遗产税,鼓励遗产捐赠等,以促进中国非政府组织的健康发展。
