Audit Publicity and Tax Compliance: A Natural Experiment

We use confidential data on value-added tax payments at the sector level, in two large Italian cities, to estimate the effect of audit publicity on the tax compliance of local sellers. By employing a difference-in-differences identification strategy, we find that such publicity has a positive effect on fiscal declarations made shortly thereafter. The results suggest that increasing awareness on future audits via the media can be an important instrument in the hands of tax authorities.     

Tax Rate Harmonization,Renegotiation, and Asymmetric Tax Competition for Profits with Repeated Interaction

This paper analyzes a model of corporate tax competition with repeated interaction and with strategic use of profit shifting within multinationals. We show that international tax coordination is more likely to prevail if the degree of asymmetry in terms of productivity differences between countries is smaller, or if concealment costs of profit shifting are larger when the tax authorities adopt grim‐trigger strategies. Allowing for renegotiation in the tax harmonization process requires more patient tax authorities to implement tax harmonization as a weakly renegotiation‐proof equilibrium. In this case, we find somewhat paradoxical situations where higher costs of profit shifting make tax harmonization less sustainable.     

On Corporate Tax Asymmetries and Neutrality

This article discusses the effects of corporate tax asymmetries under investment irreversibility. We introduce a tax scheme where the tax base is given by the firm's return net of a rate of relief. When the firm's return is less than the imputation rate, however, no tax refunds are allowed. Unlike symmetric tax systems, the scheme proposed is neutral with respect not only to income uncertainty but also to policy uncertainty.     

Feasible Net Income Distributions under Income Tax Evasion: An Equilibrium Analysis

We investigate how redistribution of income is affected by the fact that income is privately observed and agents may not be truthful in their reports to tax authorities. In response, the government establishes an audit mechanism with penalties. Adhering to a signaling equilibrium concept, we prove that agents resort to mixed strategies, which makes it difficult for tax authorities to identify the true types. The audit strategy has a cutoff property: All income declarations below the pivotal income are audited with a constant probability; other declarations are not audited. In spite of not necessarily being truthful, agents whose true income is below or equal to the pivotal income pay their liability and, consequently, the government is implementing the designated tax schedule for those agents. In equilibrium, penalties and tax corrections equal the audit cost. Consequently, the audit system does not contribute directly to revenues, and its role is restricted to supporting the equilibrium.     

Asymmetric Capital Tax Competition with Profit Shifting

This paper analyses capital tax competition between jurisdictions of different size when multinational firms can shift some fraction of their tax base between them. For the case of revenue maximizing governments, we show that introducing profit shifting will not generally increase downward pressure on tax rates. We find that profit shifting decreases the tax-base sensitivity of the low tax jurisdiction while increasing the sensitivity of the high tax jurisdiction. Tax rates will converge as a result of additional profit shifting opportunities. This will be the case even though in general equilibrium tax rates in both jurisdictions may decrease or increase.     

Tax rebating of exports and the balance of payments

Tax rebating has recently been given heavy emphasis as a means of improving a country's balance of payments and recommendations have been made for the substitution of taxes that are fully rebated on exports for taxes that are only partly rebated or are not rebated at all. This paper gives the conditions under which tax rebating would improve a country's balance of payments. It shows that whether tax rebating of exports improves the balance of payments or not depends upon the size of the price elasticity and of the import component of exports. It then shows that, with the available evidence concerning the size of the price elasticities and of the import components in a number of European countries, export rebating may harm rather than improve their balances of payments.

Comparing Tax and Tax Reallocation Payments in Financing Rail Noise Abatement Programmes: Results from a Stated Choice Valuation Study in Italy

The paper examines the use of stated choice experiments (SC) to assess the economic value of alternative rail noise reduction interventions on the Brennero railway in Italy. The paper formally tests the econometric robustness of the SC estimates under three payment regimes: (a) a regional tax, where consumers must trade off welfare gains due to noise reduction for part of their income; (b) a transport tax reallocation scheme, where consumers must trade off a part of the tax payments that are currently spent on the public transport sector; and (c) an administration tax reallocation scheme, where consumers must trade off a part of the tax payments that are currently spent on the administration sector. The test results are varied. On the one hand, the SC estimates are found to be statistically different for the tax reallocation and the tax introduction regimes. This confirms previous valuation research results, and thus reiterates the hypothesis that states the inequality between marginal values of private income and public money. On the other hand, the SC estimates are not found to be statistically different for the two proposed tax reallocation regimes, suggesting that, in the case study investigated here, the marginal value of public money does not depend upon the budget source.     

Tax Reform and Progressivity

The established theory of tax progressivity cannot handle basic tax reform questions, such as whether an increase in personal allowances makes the tax system more progressive, because the core results assume that tax liability is never zero. This paper generalises the core theory to allow for zero tax payments, and applies the new framework to the analysis of allowances, income-related deductions and tax credits. Log concavity of the tax schedule—a property quite distinct from any existing notion of progressivity—emerges as the critical determinant of whether the distribution of the tax burden becomes more progressive as allowances are increased.     

Tax collection lags and the revenue-maximising inflation

When tax payments take place with a considerable time lag, inflation erodes part of their real value, and this loss may be comparable or even surpass the well-known gains from seigniorage. The paper finds that for the economy of Greece, a reduction of inflation will actually raise the total sum of tax collection and seigniorage, thus easing and not aggravating the debt-accumulation process.     

Security Returns and Tax Aversion Bias: Behavioral Responses to Tax Labels

This article studies behavioral responses to taxes in financial markets. It is motivated by recent puzzling empirical evidence of taxable municipal bond yields significantly exceeding the level expected relative to tax exempt bonds. A behavioral explanation is a tax aversion bias, the phenomenon that people perceive an additional burden associated with tax payments. We conduct market experiments on the trading of differently taxed and labeled securities. The data show an initial overvaluation of tax payments that diminishes when subjects gain experience. The tax deduction of expenses is valued more than an equivalent tax exemption of earnings. We find that the persistence of the tax aversion bias critically depends on the quality of feedback. This suggests that tax aversion predominantly occurs in one-time, unfamiliar financial decisions and to a lesser extent in repetitive choices.     

Wages and International Tax Competition

We introduce wage bargaining and private information into a model of profit shifting and tax competition between a large and a small country. Shifting profits to the small country not only reduces a firm's tax bill but also creates private information on profitability, altering the wage bargaining in favor of the firm. This additional shifting incentive makes the tax base of the large country more elastic and leads to higher outflows, lower wages, higher firm profits and lower equilibrium tax rates. Tax rates are no longer the only determinant of the direction and extent of profit shifting.

控制权性质影响税收敏感性吗?——基于企业劳动力需求的检验

西方学者研究表明企业所得税是劳动力需求的重要影响因素,这一理论在中国是否适用?中国大部分上市公司为国有控股企业,这一特殊的制度背景是否会影响企业所得税与劳动力需求的关系?本文基于2007年企业所得税改革这一外生政策变化,在检验西方企业所得税与劳动力需求关系的理论在中国是否适用的基础上,就不同控制权的性质是否会影响企业劳动力需求的税收敏感性进行了检验。研究发现企业所得税税率降低和"就业税盾"增加提高了企业劳动力需求,但这种税率和"就业税盾"的变化对国有控股企业劳动力需求变化的影响要显著小于非国有控股企业。这表明税收是影响企业劳动力需求的重要因素,但国有控制权使得这种税收敏感性变弱。本文的研究结果不仅丰富了相关领域的国际学术文献,而且对我国就业政策的制定具有政策含义。     

Replacing Corporate Income Tax with a Cash Flow Tax

We design a parsimonious cash flow tax for Australia and estimate revenue effects. It allows immediate deduction of all capital expenditures, denies deductions of interest payments, and compensates negative cash flows at the same rate and time as it taxes positive cash flows. It allows taxpayer timing choice on implementation over 10 years. It has incentive effects comparable to lowering the corporate income tax rate to zero. It removes distortions that artificially favour debt over equity, short- over long-term investments, rents over competitive returns, large, established over small and new businesses, and conventional over innovative investments. It closes international tax evasion loopholes. Its spur to investment and timing of revenue impacts favours implementation in recession.     

Revenue and Progressivity Neutral Changes in the Tax Mix

There has been much debate about the redistributive implications of a consumption tax and the treatment of low income households. This article presents a general model which allows for the interdependence between income and consumption taxes, while allowing for transfer payments to the low paid. The appropriate adjustment of transfer payments in response to a change in the tax mix, in order to maintain a fixed real value of transfers, is examined. The use of exemptions, of those goods for which the proportion of expenditure falls as total household expenditure rises, in order to increase the progressivity of consumption taxes is also considered. The model enables changes in the tax mix, which are both revenue and progressivity neutral, to be devised.     

International Outsourcing,Tax, and Patent Protection

We show the implications of strengthening patent protection in a developing country in the presence of a vertical technology transfer, which, despite its empirical relevance, did not get due attention in the literature. We show that if there is imperfect knowledge spillover under a weak patent protection, a strong patent protection in the developing country increases the profit of the developed‐country firm if there is a uniform tax rate in the developing country. However, if there is either perfect knowledge spillover under weak patent protection or discriminatory tax policy in the developing country, the profits of the developed‐country firms are the same under weak and strong patent protections in the developing countries.     

Royalty taxation under tax competition and profit shifting

Multinational corporations increasingly use royalty payments for intellectual property rights to shift profits globally. This not only threatens the tax base of countries worldwide but also affects the nature of tax competition. Against this background, our theoretical analysis suggests a surprising solution to the problem of curbing profit shifting without suffering major outflows of capital: a strictly positive withholding tax on royalty payments is both the Pareto-efficient solution under international coordination and the optimal unilateral response. If internal debt is sufficiently responsive, governments can even implement optimal targeting. Then, the royalty tax closes the profit-shifting channel, while all competition for mobile capital is relegated to internal-debt regulation. Our results question the ban on royalty taxes in double tax treaties and the EU Interest and Royalty Directive.     

How Profit Shifting May Increase the Tax Burden of Multinationals: A Simple Model with Discrete Investment Choices

This paper models a Stackelberg tax setting game between two revenue‐maximizing countries which compete for the location of a single production plant owned by a multinational firm. We introduce the possibility of profit‐shifting activities by the multinational firm and investigate how a change in the costs of profit shifting affects equilibrium tax rates, revenue, and the tax burden of the multinational firm. We show that in most cases, tax rates of the two countries will be higher under profit shifting than without. If the costs for profit shifting are not too low, the strategic adjustment of profit tax rates will typically harm the multinational firm.     

Tax subsidies,the rational demand for insurance and the health care crisis

An individual's optimal insurance coverage depends on balancing his gain through avoiding risk against his loss through the distortion of demand. The U.S. tax system subsidizes the purchase of excessive health insurance by excluding employer premium payments from employees' taxable incomes and by permitting the deduction of a portion of individual premiums. The current operational model of demand for health insurance shows that the tax subsidy does substantially increase insurance coverage. Since much of the rise in health care costs can be attributed to the growth of insurance, the tax subsidy is responsible for much of what is widely perceived as a health care crisis.
