环境税率、双重红利与经济增长

本文构建了一个包含环境税、污染存量和预期寿命的世代交替模型,研究环境税对环境红利和经济发展红利的影响。基于新古典增长模型的研究表明,环境税能够实现双重红利(环境红利和经济发展红利),这契合“绿水青山就是金山银山”的绿色发展理念。从传导机制看,环境税通过负收入效应使得资本积累下降,同时,环境税通过健康效应使得预期寿命延长,这又使得资本积累增加。环境税通过影响资本积累,进而影响环境质量和经济发展。此外,环境税率上升使得用于环境治理的政府支出增加,这使得经济更容易产生环境红利。基于内生增长框架的分析表明,环境税有助于摆脱“环境贫困陷阱”,这为解释国家之间的收入差距提供了一个参考机制。数值模拟结果显示,在新古典增长框架和内生增长框架下,均存在最优的环境税率可以极大化人均产出和经济增长率。本文认为,合理的环境税率有助于推进减污降碳协同治理。

Pollution Externalities in a Model of Endogenous Fertility and Growth

An endogenous growth model with human capital formation, pollution caused by production of consumption goods, and endogenous fertility decisions made by altruistic agents with infinite horizons is presented. Consequences for optimal policy of modelling fertility as an explicit decision variable are examined. Because ordinary lump-sum transfers to individuals are no longer neutral, either revenue from a pollution tax must be redistributed to dynasties (working as an implicit tax on child births), or lump-sum transfers must be supplemented with an explicit fertility tax. Alternatively, the government can avoid distortions of the fertility decisions by maintaining an appropriate public debt. When abatement is highly productive, it can be optimal to subsidize fertility in order to increase total production.     

Free Cash Flow,Shareholder Value,and the Undistributed Profits Tax of 1936 and 1937

In 1936, the Federal Government unexpectedly imposed a tax on undistributed corporate profits. Despite the direct costs of the tax, its announcement produced a positive revaluation of corporate equity, particularly among lower-payout firms. We interpret this as evidence of a divergence between managerial and shareholder preferences regarding dividend payout policies, consistent with the presence of agency costs. We also find that despite the incentives created by the tax, the actual growth in dividends during 1936 was lower among firms judged more likely to be subject to higher agency costs after controlling for liquidity, debt, and the growth in earnings.     

Reciprocity in Corporate Tax Compliance—Evidence from Ozone Pollution

In a tax—public goods reciprocity framework between citizens and the state, managers view taxes as a payment to the government in exchange for public goods, and hence they adjust their willingness to pay taxes as public good quality changes. We show that corporate tax planning intensity increases with ground-level ozone pollution. Revisions in ozone pollution regulations cause counties that failed the revised and more stringent standards to reduce ozone pollution. Consequently, firms headquartered in these counties reduced corporate tax planning intensity relative to firms in other counties. The ozone-tax link varies in the predicted directions with public attention to pollution, potential welfare loss due to ozone, managers’ stakeholder orientation, taxpayers’ polluting status, political preferences, and civic norms. We also find consistent results for Superfund cleanups of hazardous waste sites. Our research sheds light on reciprocity as a potential mechanism influencing corporate tax compliance.     

Tax reform, the informal economy, and bank financing of capital formation

This paper develops a model that relates businesses’ entry into the underground economy to tax rates and the need to access the banking system. The model uses a dynamic approach in which both firms and banks optimize and in which the benefits to a firm of accessing the banking system are endogenous. A firm compares the return to capital with the marginal tax rate on capital income and uses the difference to determine how much of the tax to pay. At the same time, banks use a firm’s capital tax payments, combined with the capital tax rate to obtain an estimate of the firm’s minimum capital value. If the firm pays at least some taxes then it will have access to the banking system, which will allow it to finance investment. If the firm pays no taxes, then it cannot access the banks and cannot invest. We compare the equilibria resulting from tax compliance and tax evasion. We calibrate the model to a highly stylized version of the Russian economy, and analyze the effect of potential tax changes on the underground economy. We compute a dynamic equilibrium for our model, and note that it tracks the path of certain macroeconomic variables of the Russian economy (GDP, budget and trade balances, price level and interest rate) with some accuracy for the years 2001–2008. We are unable to track the underground economy, as this data is unobservable. We then carry out a series of counterfactual simulations, first asking if non-capital intensive firms have an incentive to evade taxes under existing value added tax rates. We find that they do, and that the incentive would have been greatly reduced if the value added tax rate had been selectively reduced for the non-capital intensive sectors. We then ask what the effect would be if the corporate tax rate were raised on capital intensive sectors. The simulations indicate that the capital intensive sectors would not increase their entry into the underground economy.     

环境保护税收政策的国际实践及借鉴

目前世界各国都力求遵循可持续发展的基本思想,实现人与自然、环境的和谐统一,其中环境保护问题是各国面临的共同难题。从上世纪70年代起,西方发达国家采用税收政策保护环境,已取得了明显的效果。学习西方发达国家环境保护税收政策的实践经验,对其在税种的开征、税收收入的使用、税收征管等方面进行研究、总结,对于我国采用税收手段保护环境,注重经济增长质量的提高具有借鉴意义。     

Corporate Tax Enforcement Externalities and the Banking Sector

We explore whether corporate tax enforcement can affect bank lending. Specifically, we hypothesize that tax enforcement efforts aimed at small and midsized enterprises (SME) can improve their information environments, which in turn could lead to increased bank commercial lending. Exploiting the regional structure employed by the IRS until 1999, we find that the corporate tax return audit probability for SMEs is associated with greater commercial lending growth for regionally focused banks. We find similar evidence when exploiting the IRS reorganization from a regional to federal system in 2000. Further results show that tax enforcement's impact on SME informational environments is at least partially responsible for this association: The impact of tax auditing on bank lending is stronger for banks facing greater informational disadvantages and in areas where SMEs face greater hold-up problems. Finally, we find that the tax audit rate is positively associated with loan portfolio quality, suggesting that tax enforcement can lead to better loan decisions. Our findings are consistent with the tax authority's mandate having important externalities on bank lending and SME access to capital, suggesting that the benefits to tax enforcement go beyond improving tax collection.     

The taxman cometh: Does tax uncertainty affect corporate cash holdings?

We examine whether firms hold more cash in the face of tax uncertainty. Because of gray areas in the tax law and aggressive tax avoidance, the total amount of tax that a firm will pay is uncertain at the time it files its returns. The tax authorities can challenge and disallow the firm’s tax positions, demanding additional cash tax payments. We hypothesize that firms facing greater tax uncertainty hold cash to satisfy these potential future demands. We find that both domestic firms and multinational firms hold larger cash balances when subject to greater tax uncertainty. In terms of economic significance, we find that the effect of tax uncertainty on cash holdings is comparable to that of repatriation taxes. Our evidence adds to knowledge about the real effects of tax avoidance and provides a tax-based precautionary explanation for why there is such wide variation in cash holdings across firms.     

A Growth Maximising Tax Structure for New Zealand

Annual growth rates of real GDP in New Zealand have varied widely, from 18% to –8%, since World War II. During this period the tax burden (the ratio of tax revenue to GDP) has trended upward from 23% to 35%. The tax mix (the ratio of indirect taxes to direct taxes) has varied between 0.31 and 0.75, having increased recently with the introduction of the goods and services tax. In this paper we estimate a combination of the tax burden and the tax mix which would maximise the rate of growth of real GDP. We find that such a tax structure would have a time-varying tax burden with a mean of 22.5%, and a time-varying tax mix with a mean of 0.54, which implies a mean share of direct taxes in total tax revenue of 65%. We also find that a move to such a tax structure would generate nearly a 17% increase in real GDP, and while this increase would yield a 6% reduction in tax revenue to the Treasury, it would deliver a 27% increase in purchasing power to the remainder of the economy.     

Corporate Social Responsibility,Tax Aggressiveness,and Firm Market Value

This paper examines the relationship of corporate social responsibility (CSR), tax aggressiveness, and firm market value. An economic model has been developed to show that profit‐maximization firms are willing to incur additional costs in CSR, such as paying more taxes, as long as they can differentiate their products from non‐CSR firms, and that socially conscious consumers will buy products from CSR firms at prices higher than those of non‐CSR firms. The empirical study in this paper indicates that the higher the CSR ranking of a firm, the less likely a firm is to engage in tax aggressiveness. It also indicates that a reputation of higher CSR will enhance firm market value. Using Canadian companies listed in the S&P/TSX 60 index, I find that both firms’ five‐year effective tax rates and annual effective tax rates are positively associated with their overall CSR scores as well as with their social scores. Firms’ five‐year effective tax rates are also positively associated with their governance index. I also find that firms’ overall CSR ranking and governance scores are positively associated with their market value.     

Effects of Capital Gains Taxation on Life-Cycle Investment and Portfolio Management

We examine the impact of capital income taxation, both accrual forms of taxation and taxation of realized capital gains, on total savings and the demand for corporate financial instruments. We find that investors may hold both debt and equity in the face of effective collection of capital gains taxation even in a flat tax system. We also find that the two taxes will have substantially different effects on saving and consumption behavior, making it unlikely that the tax structure can be summarized by any single equivalent accrual tax rate.     

Tax Havens,Tax Evasion and Tax Information Exchange Agreements in the OECD

Using data on Foreign Portfolio Investment (FPI), we find a positive relationship between higher tax burden and OECD residents’ tax evasion, especially via tax havens. Contrary to established investor preference for certain country characteristics, we find they are less important to tax evaders who value privacy and want to remain undetected by their home tax authorities. We find very limited evidence that OECD Tax Information Exchange Agreements (TIEAS) reduce tax evasion, controlling for other determinants of overall OECD FPI. Without the US in the OECD sample, tax havens play a lesser role and OECD policies appear to make a marginal impact.     

Tax avoidance,tax management and corporate social responsibility

This study examines the effect of three measures of corporate social responsibility (CSR) — corporate governance, community and diversity on tax avoidance in firms that use auditor‐provided tax services. This is one of the first studies, to our knowledge, to empirically relate tax avoidance, tax management and CSR literature. By separating the strengths and concerns for each CSR measure, we are able to analyze the effects of a firm's negative and positive social actions on tax avoidance. We find that the interaction of community concerns with tax management fees positively affects both GAAP and Cash ETR, while the interaction of corporate governance strengths and diversity concerns with tax management fees negatively affects Cash ETR. Our results are similar when we use Excess ETR that is not explained by firm specifics. We find additional evidence that CSR affects tax avoidance when we divide firms into portfolios based on CSR levels. Our findings suggest that future studies on tax avoidance and tax management should incorporate CSR.     

Tax Setting in a Federal System: The Case of Personal Income Taxation in Canada

In a decentralised tax system, the effects of tax policies enacted by one government are not confined to its own jurisdiction. First, if both the regional and the federal levels of government co-occupy the same fields of taxation, tax rate increases by one layer of government will reduce taxes collected by the other. Second, if the tax base is mobile, tax rate increases by one regional government will raise the amount of taxes collected by other regional governments. These sources of fiscal interdependence are called in the literature vertical and horizontal tax externalities, respectively. Third, as Smart (1998) shows, if equalisation transfers are present, an increase in the standard equalisation tax rate provides incentives to raise taxes to the receiving provinces. A way to check the empirical relevance of these hypotheses is to test for the existence of interactions between the regional tax rate, on the one hand, and the federal tax rate, the tax rate set by competing regions, and the standard equalisation tax rate, on the other hand. Following this approach, this paper estimates provincial tax setting functions with data on Canadian personal income taxation for the period 1982–1996. We find a significant positive response of provincial tax rates to changes in the federal income tax rate, the tax rates of competing provinces, and the standard equalisation rate (only for receiving provinces). We also find that the reaction to horizontal competition is stronger in the provinces that do not receive equalisation transfers.     

Political Sustainability and the Design of Environmental Taxes

This paper studies the issue of political support for environmental taxes. The environmental tax is determined by majority voting, given a refund rule that specifies the allocation of tax proceeds. The refund rule is chosen by a welfare-maximizing constitutional planner. We show that: (i) The equilibrium tax rate is increasing in the proportion of tax reductions based on wage incomes. (ii) If labor and capital income taxes are reduced in the same proportion, to keep the government's budget balanced, majority voting yields a rate of environmental taxation that is lower than the optimal (Pigouvian) level. (iii) To mitigate this negative bias, the government reduces wage taxes by a higher proportion than capital income taxes. (iv) The final outcome will either be the Pigouvian tax or else all reductions will be given in wage taxes. This depends on individuals' preferences for the polluting good as well as wage and capital income distributions.     

Does corporate tax avoidance promote managerial empire building?

We examine the association between corporate tax avoidance and empire building using 35,060 firm-year observations from the United States (US) for the period 1991–2015. We build a composite empire building measure by conducting a factor analysis on four popular empire building proxies used in the literature. We find a positive association between this composite measure and the four proxies used to represent the tax avoidance of firms in our sample. As our results suggest, agency problems are inflicted upon firms employing tax avoidance strategies which, in turn, facilitate managerial rent extraction through aggressiveness in growth and the accumulation of assets. Furthermore, the relationship of corporate tax avoidance to managerial empire building is found to be more pronounced in firms with weak governance, poor monitoring mechanisms, greater Chief Executive Officer (CEO) power and weak corporate social responsibility (CSR) performance. We also find that empire building-motivated tax avoidance leads to lower firm valuation. Our results remain insensitive even when employing several robustness tests.     

Strategic reaction and tax avoidance: Evidence from the effect of large IPOs on peers

We examine whether and how industry peers use tax avoidance as a strategic mechanism to maintain their relative competitive positions. We exploit a unique setting where a relatively large private firm obtains capital, visibility, and creditability by going public (i.e., an IPO), imposing significant competitive pressure on its industry peers. We find that peer firms increase tax avoidance after large IPOs. Further analysis shows that the increase of tax avoidance is driven by firms with high growth needs and firms with high operating uncertainty, suggesting that tax aggressiveness is aligned with other strategic risk-taking changes to improve industry competitiveness. We rule out two alternative explanations: 1) existing peers use relative product market power to hedge against tax risk and engage in tax avoidance; 2) peers mimic the tax avoidance behavior of IPO firms. The main finding is supported by the difference-in-differences test with coarsened exact matching and a battery of robustness tests, including alternative measures and alternative large IPO selection criteria.     

不同投资模式下公司避税效应的非对称性研究——基于双阶差分模型的实证检验

运用双阶差分模型探究了并购与新建投资模式下公司避税效应的非对称性,并进一步从事后的视角探究该非对称性是否是影响企业投资模式选择的显著影响因素。研究发现：相比于新建投资,并购增加了收购方会计利润应税所得差异,且实质性地降低了其所得税实际有效税率,这表明不同投资模式下公司避税效应存在理论预期的非对称性。进一步研究发现,改变企业会计利润应税所得差异以及会计利润应税所得操纵程度是影响企业投资模式选择的重要因素。从事后的视角来看,企业很可能为了获取更大程度的公司避税效应而选择并购行为。     

Human Capital Spending,Inequality, and Growth in Middle-Income Asia

Asia’s rapid population aging fortifies the case for strengthening human capital investments. Further, the experience of the newly industrialized economies suggests that human capital investments will be a vital ingredient of the transition from middle income to high income. Those investments can also affect equity and public finances. In this article, we use data from the National Transfer Accounts to empirically analyze the effect of human capital investment in Asian countries on economic growth, inequality, and fiscal balance. Our empirical evidence suggests that human capital investments have a positive effect on labor productivity and, hence, output. The positive effect is stronger for poorer households and, hence, beneficial for equity. We also find that such investments can generate sufficient tax revenues to improve the fiscal balance. Overall, our evidence points to a positive effect of human capital on growth, equity, and fiscal balance in Asia.
