Federal tax policies,congressional voting and natural resources

Can abundance of natural resources affect legislators' voting behaviour over federal tax policies? We construct a political economy model of a federalized economy with district heterogeneity in natural resource abundance. The model shows that representatives of natural resource‐rich districts are more (less) willing to vote in favour of federal tax increases (decreases). This occurs because resource‐rich districts are less responsive to federal tax changes due to the immobile nature of their natural resources. We test the model's predictions using data on roll‐call votes in the US House of Representatives over the major federal tax bills initiated during the period of 1945–2003, in conjunction with the presence of active giant oil fields in US congressional districts. Our identification strategy rests on plausibly exogenous giant oil field discoveries and exploitation and narrative‐based aggregate federal tax shocks that are exogenous to individual congressional districts and legislators. We find that: (i) resource‐rich congressional districts are less responsive to changes in federal taxes and (ii) representatives of resource‐rich congressional districts are more (less) supportive of federal tax increases (decreases), controlling for legislator, congressional district and state indicators. Our results indicate that resource richness is approximately half as dominant as the main determinant, namely party affiliation, in driving legislators' voting behaviour over federal tax policies.     

Redistributive Taxation under Ethical Behaviour*

We consider the implications of ethical behaviour on the effect of a redistributive tax‐transfer system. In choosing their labour supplies, individuals take into account whether their tax liabilities correspond to what they view as ethically acceptable. If tax liabilities are viewed as ethically acceptable, a taxpayer behaves ethically, does not distort her behaviour, and chooses to work as if she were not taxed. On the other hand, if ethical behaviour results in tax liabilities that exceed those that are ethically acceptable, she behaves egoistically (partially or fully), distorts her behaviour, and chooses her labour supply taking into account the income tax. We establish taxpayers' equilibrium behaviour and obtain that labour supply is less elastic when taxpayers may behave ethically than when they act egoistically. We characterise and compare the egoistic voting equilibrium linear tax schedules under potentially ethical and egoistic behaviour. We also compare our results to those obtained under altruism, an alternative benchmark.     

论个税自行申报——导引价值、制度障碍与对策

个税自行申报具有培育纳税人权利与责任意识、收集纳税人信息,有效监控税源和倒逼税制改革等导引价值。然而,现行个人所得税制的分类征收方法、"一刀切"扣除项目以及完税凭证协查机制等与个税自行申报存在诸多矛盾,这是个税自行申报元年遇冷的根本原因。因此,应把个税税制改革作为个税自行申报有效运行的突破口。     

Externality‐Correcting Taxes and Regulation*

In much of the literature on externalities, taxes and direct regulation have been considered as alternative policy instruments. Both instruments might be imperfect in practice, reflecting informational deficiencies and other limitations. We analyse the use of taxes and regulation in combination, to control externalities arising from individual consumption behaviour. We consider the cases either where taxes are imperfectly differentiated to reflect individual differences in externalities, or where some consumption escapes taxation. In both cases, we characterize the optimal instrument mix, and we show how changing the level of direct regulation alters the optimal externality tax.     

The experience of some OECD economies on tax smoothing

Observed random walk behaviour of a tax rate does not necessarily support the tax smoothing hypothesis though the latter implies the former. This article presents a direct test of tax smoothing by showing that if the tax smoothing hypothesis holds then the future tax rate should cointegrate with the current permanent government expenditure rate even though the tax rate is a random walk. This test is a direct and robust test of a number of ‘random walk models’ available in the literature. This procedure also enables us to differentiate among ‘strong tax smoothing’, ‘weak tax smoothing’ and ‘no-tax smoothing’, all of which are consistent with the random walk behaviour of a tax rate. Application of this test to Australia, Canada, Italy, Japan, the Netherlands, New Zealand, the UK and the US show evidence in support of weak forms of tax smoothing.     

Who participates in tax avoidance? Evidence from Swedish microdata

This article empirically examines why not all individuals participate in tax avoidance. We use rich Swedish administrative panel data on all taxpayers, with a link between corporate and individual tax returns and document that few individuals utilize legal and observable tax avoidance opportunities. Our results show that there are several frictions in tax avoidance participation. In addition to monetary benefits from tax avoidance (incentives), the opportunity to participate in tax avoidance (access), as well as information and knowledge about these opportunities (awareness), are important factors for the individual’s tax avoidance decision. We further show that tax avoidance spreads within communities. The impact of the local network is stronger for non-commuters who live and work in the same municipality.     

Junk-food,home cooking,physical activity and obesity: The effect of the fat tax and the thin subsidy

In an effort to reduce the growing prevalence of obesity, a tax on junk-foods, known as ‘fat tax’, has been proposed, the revenue from which could be used to finance a ‘thin subsidy’ for healthy foods or exercising equipment. The present paper addresses the fat tax and thin subsidy within a food-intake rational-choice model. Assuming that healthy meals are cooked at home with purchased ingredients and time input, the paper examines the effects on obesity of a tax on junk-food meals and a subsidy to cooking ingredients, distinguishing between a weight-conscious and a non-weight conscious individual, and between a weight-conscious individual who is physically active and physically inactive. The results show that for a non-weight conscious individual a fat tax will unambiguously reduce obesity, whereas a thin subsidy may increase obesity. However, for a weight-conscious individual, particularly one who is physically active, even a fat tax may increase obesity, as it may reduce not just the consumption of junk-food, but also the time devoted to physical activity. The paper explores conditions under which obesity will rise, fall, or remain intact following the introduction of a fat tax or a thin subsidy.     

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.     

Welfare impacts of equal-yield tax reforms in the UK economy

A multisectoral dynamic general equilibrium tax model with and without announcement effects for open and closed capital markets is used to evaluate efficiency gains and transitional effects from equal-yield tax reforms for seven different taxes in the UK economy. Impacts of an unanticipated tax reform on investment, capital accumulation, output and employment are compared to those of anticipated tax reforms. Households, producers, traders, investors and the government are found to be more capable of adjusting their economic behaviour when tax announcements are made in advance. In equal-yield tax experiments welfare gains up to 1.4% of base year GDP can occur by removing distortions in taxes. Welfare loss of up to 2.05% of it can happen if a less distortionary tax, such as the labour income tax is replaced by more distortionary taxes. These simulation results hold whether the capital markets are closed or open.     

Imperfect Capital Mobility and Local Government Behaviour in a Two‐Period Economy

One clear result in the tax competition literature is that, when head taxes on immobile residents are available, the optimal capital tax rate for local government is zero. However, zero tax rate, when resident taxes are available, is incompatible with the phenomenon actually observed. In most countries, local governments use capital taxes as policy variables for choosing a nonzero tax rate. This paper presents a model of a two‐period economy with imperfect mobile capital to explain the behaviour of local government providing capital subsidies on capital. It further examines an equilibrium tax rate where local government’s objectives include Niskanen‐type revenue‐maximizing.     

Moral Hazard,Income Taxation and Prospect Theory*

The standard theory of optimal income taxation under uncertainty has been developed under the assumption that individuals maximise expected utility. However, prospect theory has now been established as an alternative model of individual behaviour, with empirical support. This paper explores the theory of optimal income taxation under uncertainty when individuals behave according to the tenets of prospect theory. It is seen that many of the standard results are modified in interesting ways. The first‐order approach for solving the optimisation problem is not valid over the domain of losses, and the marginal tax schedule offers full insurance around the reference consumption level. The implications of non‐welfarist objectives under income uncertainty are also examined.

A tax discrepancy coefficient resulting from tax evasion or tax expenditures

Tax evasion and tax expenditures introduce discrepancies between taxpayers. In this paper, a tax discrepancy coefficient has been worked out in order to establish, given a constant tax yield, what bigger or smaller amounts taxpayers would have to pay if tax evasion or tax expenditures were completely eliminated. After the definition of the coefficients these are calculated for individual income tax returns in Belgium. Similar coefficients can be established for other types of taxation, such as inheritance tax, corporate income tax or even sales tax (e.g. V.A.T.).     

The Laffer curve in schedular multi-rate income taxes with non-genuine allowances: An application to Spain

This paper models the connection between tax revenue and marginal tax rates in modern personal income taxes. In so doing, new analytical expressions for the elasticity of tax revenue to tax rates are derived taking into account global and schedular income taxes in the presence of non-standard allowances. Based on these new analytical elasticities the implicit Laffer curve is characterised and explored in detail. Calculations are performed for the individual taxpayer and the aggregate population. When applied to microdata, the model permits us to locate individually the position of every taxpayer on the entire range of the Laffer curve as well as to characterise the “representative” aggregate Laffer curve. The utility of the model to forecast revenue is illustrated by applying it to Spanish personal income tax. The model confirms that the Laffer curve is essentially an intrinsic individual matter although a virtual aggregate Laffer curve for the whole population can be inferred.

Are corporate tax rates, or countries, converging?

The statutory rate and effective tax rate imposed on corporation income—as well as the dispersion of these rates—began to decline in the 1980s. Is this due to changes in the domestic determinants of corporate taxation or increases in international pressures for tax competition?This paper finds clear evidence that the corporate tax rate is insulated from a country's revenue needs: across countries, there is no association of the expenditure-GDP ratio with the corporate statutory rate and only weak evidence of a positive association with the average rate. There is suggestive, but not definitive, evidence that the domestic role of the corporate tax as a backstop to the individual income tax is important: across countries, there is indeed a strong association between the top individual rate and the top statutory corporate rate.There is intriguing evidence about the role of international competitive pressures on corporate taxation. Measures of openness are negatively associated with statutory corporate rates, although not with revenues collected as a fraction of GDP. Strikingly, larger, more trade-intensive countries do collect more corporate tax, but this may be because these countries are more attractive venues for investment.     

Taxation and Market Power

We analyze the incidence and welfare effects of unit sales tax increases in experimental monopoly and Bertrand markets. We find, in line with economic theory, that firms with no market power are able to shift a high share of the tax burden to consumers, independent of whether buyers are automated or human players. In monopoly markets, a monopolist bears a large share of the burden of a tax increase. With human buyers, however, this share is smaller than with automated buyers, as the presence of human buyers constrains the pricing behaviour of a monopolist. Several control treatments corroborate this finding.

Do your tax problems make tax evasion seem more justifiable? Evidence from a survey experiment

Taxpayers often view tax rules and filing processes as complicated. I study whether the perceived tax uncertainty among peers makes tax evasion more acceptable among the general public. I find strong supportive evidence for this hypothesis using a survey experiment and a large representative sample of the German population. Providing randomized information that others are uncertain about how to file their taxable income decreases individual support for tax compliance. This suggests that subjects judge tax evasion less harshly in response to this peer information. Studying related heterogeneous treatment effects, I find that both older and left-wing subjects are more responsive to tax uncertainty of others. Less harsh views on evasion are persistent for very high compliance levels in a follow-up survey.
