THE POTENTIAL FOR SHORT‐RUN SHIFTING OF A CORPORATE PROFITS TAX

Can the owners of a firm shift a corporate profits tax to consumers? Not in the short run if the tax is stated as a proportion of profits and the firm is a profit maximizer. But what if the firm wishes to pursue a strategy other than profit maximization, say revenue maximization subject to a profit constraint? Under such a condition the firm's reaction to a tax or tax increase might be a price rise that captures part of the foregone profits. We show that firms which operate at a point on their demand curve that differs from profit maximization have an incentive to raise price in response to the tax – and that high cost firms have a greater incentive to raise price than do low cost firms. Our empirical analysis of the US beer industry confirms this finding, and sheds light on the Krzyzaniak–Musgrave analysis of the 1960s which suggested that the corporation income tax produced significant short‐run shifting.     

The tax advantage of public firms over private firms in the German household solid waste disposal industry

We measure the tax advantage of public firms over private firms, which operate at municipality level in the German household solid waste disposal industry. Public firms with sovereign duties pay no taxes, but equivalent private firms have to. In a simple risk-free setting, we develop a measure of the percentage difference of the charges of both types of firms demanded under their respective tax treatments. We model a cost-covering public firm and a net present value maximizing private firm. For sensible model parameters from the German waste disposal industry the private firm has to demand an about 16% to 18% higher charge. The by far biggest impact on the measure has the value added tax, with revenues as a much larger tax base than profits. Tax savings, which directly affect pre-tax profits, only alleviate the disadvantage bit. There is some evidence that at least one type of private firms—that is, private law firms that are also majority privately owned, are productive enough to overcome the tax advantage of public firms and be able to charge a lower price than public firms.     

Numerical simulation on property tax reform: evidence from China

This article analyses the property tax reform in China in a computable general equilibrium model that recognizes the interaction between and among housing markets in different provinces and macroeconomic development. Using real data in 2010, we present the benchmark equilibrium for reference property and income tax rates. Then, we examine different property and income tax policies and make a comparison of their production, consumption, welfare and national income. We find that the implementation of property tax would decrease the house production at the expense of welfare in taxed area. The expansion of the taxed regions may increase the total social welfare and national income. Even though property tax policy may not be able to change the income distribution in China, increasing income tax rate could narrow the income disparity. Finally, this article shows the reliability of the conclusions when sensitivity analysis on optimal condition of equilibrium computation is performed under varied property tax policy.     

Taxation and corruption: theory and firm-level evidence from Uganda

This article develops a simple framework to analyse the negotiation over bribe and tax payments during the tax collection process. We show that the larger the bribe a firm offers to a tax collector, the larger the tax rebate it gets. More particularly, we show that the negotiation over bribe and tax payments hinges on four other factors: firms’ official liabilities, detection, firms’ negotiation power and red tape costs imposed on firms. Some of the predictions from the theoretical model are tested using firm-level data from Uganda. We find that bribe and tax payments are inversely related, thereby supporting the hypothesis of a negotiation taking place between firms and tax collectors. In particular, a 1% point increase in average bribe payments per employee is associated with a 7% point reduction in average amount of tax payments per employee. Results are robust to various instruments dealing with the endogenous relationship between bribes and taxes.     

Income Shifting within a Dual Income Tax System: Evidence from the Finnish Tax Reform of 1993*

Dual income tax systems can suffer from income that shifts from progressively taxed labour income to capital income, which is taxed at a lower, flat rate. This paper empirically examines the 1993 Finnish dual income tax reform, which radically reduced the marginal tax rates on capital income for some, but not all, taxpayers. We measure how overall taxable income and the relative shares of capital income and labour income reacted to the reform. We find that the reform led to a small positive impact on overall taxable income, but part of the positive response was probably offset by income shifting among the self‐employed.     

Taxes and firm investment

We investigate the firm-level investment response to unanticipated narrative shocks to average personal and corporate tax rates using a universal micro dataset of publicly-traded U.S. firms for the post-1976 period. Using local projections, we show that: (i) corporate tax shocks have significant effects on investment while personal tax shocks do not; (ii) corporate income tax responses are negative overall, and this result is driven by smaller firms who face larger borrowing constraints, especially when the accompanying monetary policy is contractionary or output gap is slack; (iii) there is some evidence of positive personal income tax responses during monetary contractions by dividend-paying firms, which is consistent with the recent literature.     

促进信息技术产业发展的税收思考

IT产业是一个比较幼稚的产业,但它对于国民经济而言又具有非常重大的现实意义。从某个角度上说,它在竞争中处于不利的地位,因而有必要对其在税收政策方面给予一定的扶持。扶持的措施是完善税收政策,改革现行的企业所得税,增值税和个人所得税,使我国的税收制度更加有利于IT产业的发展。     

Fiscal policy under a minimum‐time objective

In an endogenous growth model, we characterize the fiscal policy driven by a minimum‐time objective of economic development. We find that in equilibrium government should levy the highest possible consumption taxes, reduce public expenditures to the lowest possible level, and keep labor income tax rate and capital income tax rate satisfy a substitution relationship at the balanced budget constraint. We also identify the condition under which income tax rate should be set to zero. We further find that the equilibrium fiscal policy is equivalent to the growth‐maximizing fiscal policy, whereas it generally deviates from the welfare‐maximizing fiscal policy. We hence identify a circumstance where setting the policy goal of reaching an economic‐performance target as soon as possible cannot be justified in the sense of maximizing the welfare of households.     

Optimal income taxation with tax avoidance

We determine the optimal income tax schedule when individuals have the possibility of avoiding paying taxes. Considering a convex concealment cost function, we find that a subset of individuals, located in the interior of the income distribution, should be allowed to avoid taxes, provided that the marginal cost of avoiding the first euro is sufficiently small. This contrasts with the results of Grochulski who shows that, using a subadditive cost function, all individuals should report their true income. We also provide a characterization of the optimal income tax curve.     

Do chairmen with China's Great Famine experience in early-life affect firm tax avoidance activities?

This article investigates whether and how chairmen with China's Great Famine experience affect firm tax avoidance activities. We find that the chairmen who experienced China's Great Famine in early-life engage in fewer tax avoidance activities than other chairmen. This effect is stronger for firms in regions with a weak gambling culture and provinces with higher political uncertainty, nonstate-owned firms, and chairmen with higher education. We show that a lower-level risk appetite among chairmen is the primary mechanism driving lower tax avoidance in their firms. Our article provides new insights into the differences in tax avoidance between firms based on whether managers experienced the Great Famine.     

企业避税与年报可读性

避税活动加剧了企业的信息不对称，管理层在信息披露中是否会采用晦涩的文本信息掩盖避税行为？本文利用2008—2017年中国A股上市公司数据，考察企业避税对年报可读性的影响及其机制。结果发现，避税活动越多，企业年报采用的复杂词汇就越多，年报可读性就越差。在运用工具变量弱化内生性问题、更替年报可读性指标与企业避税指标、考虑递延所得税信息披露和税收政策影响等一系列稳健性检验后，避税行为降低企业年报可读性的结论依然成立。机制分析发现会计信息质量在避税行为对年报可读性的影响中发挥了部分中介作用，避税活动通过降低会计信息质量削弱了年报可读性，信息披露中文本信息与数字信息相配合的观点从企业避税视角得到了验证。此外，在无税收优惠、递延所得税负债较多和外部治理环境较差的企业中，避税降低年报可读性的现象更为明显。因此，规范企业税收制度能够减少企业避税、限制管理层寻租行为，促进税收透明化，从而提高企业的信息披露质量。     

Outsourcing of accounting tasks and tax management: evidence from a corporate tax rate change

The aim of this article is to investigate if small firms react to a national corporate tax rate reduction by managing their taxable income. In contrast to previous studies, we also analyse whether outsourcing of accounting tasks affects the magnitude of the reaction. Based on a sample of Finnish firms and measures of earnings management, evidence is provided that firms with an internalized accounting function are more active tax planners in this context. This study suggests that outsourcing of accounting tasks increases the corporate tax reporting quality.

中国地方政府间的企业所得税竞争研究* ——基于面板数据空间滞后模型的实证分析

中国地方政府没有独立的税收立法权,但仍然可以通过企业所得税优惠开展中国式税收竞争。本文在构建省级企业所得税优惠衡量指标的基础上,使用面板数据空间滞后模型分析表明,中国地方政府间存在无序的策略互补式税收竞争,并且在企业所得税名义税收优惠上的竞争比实际税收优惠更为激烈。中央政府有必要从企业所得税名义税收优惠入手,采取措施规范地方政府间的企业所得税竞争行为,但同时也应该保持税收优惠政策本身及其实施效果的连续性。     

Redistribution with Unobservable Bequests: A Case for Taxing Capital Income

This paper addresses the question of the optimal taxation of labour and interest income in an overlapping generations model with two unobservable characteristics, ability and inheritance. We assume realistically that saving can only be taxed anonymously, whereas the tax on labour earnings can be individualized and made non-linear. In such a setting, we show that a withholding tax on interest income along with a non-linear tax on labour income is desirable. The role of interest income taxation is to indirectly tax inherited wealth.

Optimal pollution taxation in a Cournot duopoly

It is well known that the optimal pollution tax in a competitive industry is equal to the marginal damage inflicted by the pollution. It has also been shown that the optimal pollution tax on a monopoly is less than the marginal damage. In this paper, I derive the optimal pollution tax for a Cournot duopoly. If firms have different production costs, the optimal tax rate may exceed the marginal damage. This is so because the tax may be an effective instrument for allocating production from the less to the more efficient firm. It is also shown that, if one firm has a positive most preferred pollution tax, the sum of consumer and producer surpluses will be declining in the tax at this level.     

The effects of progressive income taxation on job turnover

We examine whether the level of the income tax rate and the convexity of the income tax schedule affect job mobility, as measured by moving to a better job. While the predicted effect of the level of the tax rate is ambiguous, we predict that an increase in the convexity of the tax schedule decreases job search activity by taxing away some of the benefits of a successful job search. Using data from the Panel Study of Income Dynamics, we estimate that both higher tax rates and increased tax rate progressivity decrease the probability that a head of household will move to a better job during the coming year. Our estimates imply that a five-percentage-point reduction in the marginal tax rate increases the average probability of moving to a better job by 0.79 percentage points (a 8.0% increase in the turnover propensity) and that a one-standard-deviation decrease in our measure of tax progressivity would increase this probability by 0.86 percentage points (a 8.7% increase in the turnover propensity). This estimate is robust to sensitivity analysis examining the importance of different sources of identification and variation in estimated effects across subgroups in the population. Our estimated importance of tax policy for job turnover suggests a potential role in explaining the responsiveness of taxable income to marginal tax rates.     

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.     

上市公司所得税率变化的敏感性分析

从 2 0 0 2年起除高科技类和西部地区的上市公司以外 ,其它上市公司不再享有所得税地方返还政策 ,而且我国加入WTO以后所得税也面临着改革。对于上市公司来说 ,法定税率 (LTR)变化对其实际税率 (ETRs)有多大的影响就成为政策制定者的一个现实的问题。本文首先对中国上市公司自 1 994— 2 0 0 0年执行的法定所得税税率的现状作一分析 ;然后 ,用 1 86家上市公司的样本进行检验 ,结果发现法定税率变化对实际税率的影响只有法定税率变化的 0 50 2 ,在分组及分年度检验中也得到了类似的结论。     

‘Earnings shocks and tax-motivated income-shifting: evidence from European multinationals’ – revisited

This article revisits the study by Dhammika Dharmapala and Nadine Riedel on income shifting between European multinationals published in the Journal of Public Economics in 2013. It used a promising alternative causal identification strategy for profit-shifting based on earnings shocks, which has over a short time period been frequently cited in the literature. Using data from the same database, albeit for a period 10 years later, for 2006–2015, the significant causal evidence for profit-shifting from European parent firms to their lower taxed European subsidiaries cannot be reproduced. Neither can similar results be obtained by considering profit-shifting to subsidiaries located anywhere in the world. Results in line with those of the original study can however be found when using effective rather than statutory corporate tax rates. While these findings raise concerns about the external validity of earlier studies’ result, it should not put the existence and extent of profit-shifting into question. It rather raises concerns about the focus on statutory tax rates in measuring profit-shifting. Moreover, rather than a decrease in profit-shifting, it may illustrate the database’s and the methodology’s limitations and ability to capture all shifts and channels.
