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.     

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。     

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.     

The macroeconomic effects of fiscal policy in a stochastically growing economy

This paper develops a stochastic model of endogenous growth with productive government expenditure. Herein, we specify the CES production function according to recent empirical evidence. The elasticity of substitution plays a key role in determining macroeconomic performance and the effectiveness of fiscal policy under uncertainty. Results demonstrate that a large elasticity of substitution provides a large expected growth rate and also large volatility of the growth rate. Regarding these effects, the growth-maximizing tax rate and welfare-maximizing tax rate under uncertainty are larger or smaller than those of deterministic economy according to the elasticity of substitution.     

Pollution Abatement Investment When Environmental Regulation Is Uncertain

In a dynamic model of a risk-neutral competitive firm that can lower its pollution emissions per unit of output by building up abatement capital stock, we examine the effect of a higher pollution tax rate on abatement investment both under full certainty and when the timing or the size of the tax increase is uncertain. We show that a higher pollution tax encourages abatement investment if it does not exceed a certain threshold rate. However, akin to the Diamond-Mirrlees tax anomaly, it is possible that a higher pollution tax rate results in more pollution. The magnitude uncertainty discourages abatement investment, but at the time of the actual tax increase the abatement investment path may shift either upward or downward. On the other hand, when the timing is uncertain, the abatement investment path always jumps upward, thus suggesting that the effect of magnitude uncertainty on the optimal investment path may be more pronounced than that of timing uncertainty. Further, we show that the ad hoc practice of raising the discount rate to account for the uncertainty leads to underinvestment in abatement capital. We show how the size of this underinvestment bias varies with the future tax increase. Finally, we show that a credible threat to accelerate the tax increase can induce more abatement investment.     

Economic Risk and Political Risk in Fiscal Unions

A fiscal programme that redistributes income from rich to poor individuals indirectly redistributes tax revenues from regions hit by a favourable shock to regions hit by an unfavourable one. Centralised fiscal redistribution has therefore been advocated as a way to insure individuals against region-specific shocks. In this paper, we argue that a centralised fiscal policy, while reducing the uncertainty on the tax base, may create additional uncertainty on the tax rate. Using a simple model we show that the higher uncertainty on the policy instrument might more than offset the lower uncertainty on the tax base.     

2011年个人所得税改革的收入再分配效应

本文考察2011年9月1日实施的个人所得税改革的收入再分配效应。根据目前我国分项课征的个人所得税征管模式,本文推导出税收的收入再分配效应指数按收入构成的分解方法。根据该分解方法的主要分析结果可概括为两点:其一,平均税率的高低是个税收入分配效应大小的主要决定因素,累进性则是次要的。由于平均税率的降低,本次税收改革弱化了本来就十分微弱的个人所得税的收入分配效应。其二,我国个人所得税整体累进性指数随工资薪金所得费用扣除的提高呈倒U型。十分巧合的是,本次改革确定的3500元免征额正好处于倒U型的最大值,超过3500元的费用扣除反而会削弱我国个税的累进性。     

Itemised Deductions: A Device to Reduce Tax Evasion

With direct incentives and sanctions being the most common instruments to fight tax evasion, the theoretical literature has tended to overlook indirect schemes, such as itemised deductions, in which one agent's behaviour affects the likelihood that others will declare their revenue. Itemised deductions provide an incentive for consumers to declare their purchases. This induces a partial shift in the demand from the black market to the legal one, for consumers need a transaction receipt to enjoy the tax deduction. I show that it is possible to increase tax proceeds by choosing a suitable level of itemised deduction, and this, for any level of taxation. Indeed, the cost for the tax authority on the consumers' side is more than compensated for by the extra proceeds generated on the sellers' side.     

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.     

Offshore Outsourcing and Productivity: Evidence from Japanese Firm‐level Data Disaggregated by Tasks

This paper examines the relationship of offshoring with productivity, based on the original survey data of Japanese firms. Productivity gains were found in the firms offshoring both manufacturing and service tasks, but not in the firms offshoring only either manufacturing or service tasks. This paper also finds that firms offshoring to various destinations tend to be more productive than non‐offshoring firms. These results suggest that the level of firms' engagement in offshoring is more important for productivity than whether or not firms engage in offshoring.     

A Note on Emissions Taxes and Incomplete Information

In contrast with what we perceive is the conventional wisdom about setting a second-best emissions tax to control a uniformly mixed pollutant under uncertainty, we demonstrate that setting a uniform tax equal to expected marginal damage is not generally efficient under incomplete information about firms’ abatement costs and damages from pollution. We show that efficient taxes will deviate from expected marginal damage if marginal damage is increasing and there is uncertainty about the slopes of the marginal abatement costs of regulated firms. Moreover, tax rates will vary across firms if a regulator can use observable firm-level characteristics to gain some information about how the firms’ marginal abatement costs vary.     

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)     

Investment behavior and the biased perception of limited loss deduction in income taxation

We use a laboratory experiment to study the extent to which investors’ choices are affected by limited loss deduction in income taxation. We first compare investment behavior in the no tax baseline to a tax control setting, in which the income from investments is taxed. We find that investors significantly reduce their risk-taking as predicted by theory. Next we compare the baseline investment choices to choices under three different types of income taxation. We observe that risk-taking is significantly increased with partial and with capped loss deduction, but is unaffected by a tax system that allows no loss deduction. Since in all these treatments the after tax outcomes of the prospects were identical, we conjecture that investors have a positively biased perception of partial and capped loss deduction that promotes their willingness to take risks.     

Offshoring and Trade Balance in Developed and Emerging Economies

This paper analyzes the effects of off‐shore outsourcing for international trade, especially for the emerging and poor economies, in a two‐sector specific factor model, with a nontraded good being one of the sectors. The phenomenon of offshoring is modeled by incorporating the reduced use of domestic labor in the production function. This is regarded as a characteristic feature of offshoring in the literature. We find that increased offshoring leads to an increase in the relative price of the nontraded good. Given that this relative price can be interpreted as the real exchange rate, increased offshoring leads to exchange rate appreciation. This suggests that offshoring actually makes the goods and services from the emerging economies more competitive in the world market, and thus can be a contributory factor in the positive trade balance experienced by many emerging economies since early 2000s.     

A note on progression,penalty schemes and tax evasion

This note deals with the question of whether shifting the tax base towards more progression will stimulate or discourage tax evasion, when the tax base is shifted so that either the expected tax revenues of government or the expected utility of taxpayer will remain unchanged. The answer turns out to depend sensitively on the nature of penalty schemes if caught in tax evasion. If the penalty rate is charged on the undeclared income, tax evasion will increase, while if the penalty rate is charged on the evaded tax, tax evasion will decrease when the tax base is shifted towards progression.

The determinants of foreign direct investment in Malaysia: A case for electrical and electronic industry

This study attempts to analyse the determinants of inward FDI in the electrical and electronic (E&E) industry in Malaysia using bounds test approach for the 1980–2008 period. It is found that GDP, real exchange rate, financial development, corporate income tax, macroeconomic uncertainty and social uncertainty factors significantly affect inward FDI in E&E sector in Malaysia. Empirical results indicate that GDP, real exchange rate, financial development and macroeconomic uncertainty are positively related to inward FDI in E&E sector in the long run. However, corporate income tax and social uncertainty have a negative impact on inward FDI in E&E sector. Furthermore, the Granger causality results also indicate that all explanatory variables Granger-cause FDI in the long-run, but in the short-run only macroeconomic and social uncertainties Granger-cause FDI. The impact of social uncertainty is found to be greater than macroeconomic uncertainty. Thus, foreign investors in E&E sector seem to be more concern about the level of social security and safety when choosing their investment destination.     

Marginal Tax Rate Uncertainty and Wage Indexation

Frequent changes in American tax laws over the last 30 years have led to uncertainty regarding the marginal tax rate on labour income. Using a multisector framework, this paper considers the implications of the tax rate uncertainty for wage flexibility. The Fiscal Authority sets the marginal wage tax rate, and is assumed to be the leader in a Stackelberg game. Wage setters in this game determine the degree of optimal indexation and are assumed to be followers. Increases in tax rate uncertainty lead to greater nominal wage flexibility, and a decrease in optimal progressivity. Additionally, indexation to nominal shocks is complete even if the product market is monopolistically competitive.     

Progressive Taxation, Tax Exemption, and Irreversible Investment under Uncertainty

We analyze the impact of progressive taxation on irreversible investment under uncertainty. We show that if tax exemption is lower than sunk cost, higher tax rate will decelerate optimal investment by increasing the optimal investment threshold, while if tax exemption exceeds sunk cost, three different regimes arise. For “small” volatilities the optimal investment threshold is a positive function of volatility, but independent of tax rate. For “medium” volatilities it is independent of both tax rate and volatility. Finally, for “high” volatilities the optimal investment threshold depends positively on volatility, but negatively on tax rate so that we have “tax paradox”.     

Corporate tax and location choice for multinational firms

This article examines the effects of corporate tax on these location decisions of newly established multinational subsidiaries across 26 European countries over an 8-year period. We contribute to the existing literature by examining the effects of a non-linear response of firm location decisions to changes in the tax rate. We also show that there are large variations in the sensitivity to tax rates across sectors and firm size groups. In particular, financial sector firms are more than twice as sensitive to changes in corporation tax rates relative to other sectors. Our baseline result is a finding that a 1% increase in the statutory or policy rate of corporation tax would lead to a reduction in the conditional location probability of 0.68%. Using the effective average tax rate, the marginal effect implies a reduction in the location probability of 1.15% following a 1% increase in the tax rate. Although overall tax has the expected negative effect on location probability, the marginal effect of an increase is lower at higher rates of tax.
