我国企业所得税整合与应对国际税收竞争的策略探析

本文认为,随着经济全球化的发展,资本在国际间的流动日益频繁,各国利用税收手段吸引流动资本的竞争也日益加剧。我国经济整体开放程度的提高将使我国经济日益融入到世界经济体系之中,客观上要求我国的税收政策必须与国际惯例接轨。我国现行的差异性企业所得税税收制度背离了WTO所要求的公平竞争的基本原则。因此,应就如何整合内外资企业所得税制的问题进行探讨和研究,以完善我国企业所得税政策,提高国际竞争力。     

Why is there so little tax coordination? The role of majority voting and international tax evasion

It is a striking feature of EU tax policy that countries find it difficult to agree on capital tax coordination. This is in conflict with the prevailing theoretical view, according to which tax coordination is beneficial. This paper develops a political economy argument which may help to explain this puzzle. We consider a model of tax competition where fiscal policy decisions are taken via majority voting and tax evasion is possible but costly. It turns out that tax coordination agreements may fail to generate political support because middle income groups may lose from tax coordination, even if their capital income is below average.     

Mathematical models describing the effects of different tax evasion behaviors

Microscopic models describing a whole of economic interactions in a closed society are considered. The presence of a tax system combined with a redistribution process is taken into account, as well as the occurrence of tax evasion. In particular, the existence is postulated, in relation to the level of evasion, of different individual taxpayer behaviors. The effects of the mentioned different behaviors on shape and features of the emerging income distribution profile are investigated qualitatively and quantitatively. Numerical solutions show that the Gini inequality index of the total population increases when the evasion level is higher, but does not depend significantly on the evasion spread. For fixed spread, the relative difference between the average incomes of the worst evaders and honest taxpayers increases approximately as a quadratic function of the evasion level.     

THE ECONOMICS OF TAXPAYER COMPLIANCE

Abstract. There is a great deal of evidence to suggest that tax evasion is now fairly extensive throughout Western Europe and North America. Academic economists have shown considerable interest in various aspects of tax evasion. In this article we examine the literature on two particular issues. First, why do individuals evade their tax obligations and second, what policies should governments pursue in attempting to reduce or eliminate evasion? We concentrate on income tax evasion which has been the major preoccupation in the literature. We first show that the compliance costs of income tax evasion are quite substantial. We then examine theoretical attempts to model individual taxpayers behaviour. Here we find that it is extremely difficult to make unambiguous predictions concerning the effects of changes in important variables, such as income tax rates. Next, we review the empirical ‘evidence’ obtained from (i) attitudinal surveys, (ii) tax games, and (iii) econometric analysis of individuals’ tax returns. All of these studies are found to be flawed in certain major respects. Finally, we consider a number of policy options available to tax authorities. Given the difficulty of determining a socially optimal level of evasion, governments are likely to pursue suboptimal policies aimed at entirely eliminating tax evasion. However, even here there is considerable disagreement about the design of an efficient policy.     

The shadow economy as an equilibrium outcome

We construct a dynamic general equilibrium model of tax evasion where agents choose to report some of their income. Unreported income requires using a payment method that avoids recordkeeping in some markets—cash. Trade using cash to avoid taxes is the ‘shadow economy’ in our model. We then calibrate our model using money, interest rate and GDP data to back out the size of the shadow economy for a sample of countries and compare our measures to traditional reduced form estimates.

Global estimates of growth–inequality–poverty (GIP) triangle: evidence from World Bank’s classification countries

This study extended the concept of ‘growth–inequality–poverty (GIP) triangle’ by using the principle component approach which allows us to composite different poverty and inequality indicators into one single index that contains most of the useful information from the original dataset. Using the idea of GIP triangle, this study examines the long-run relationship among weighted poverty index (which comprises headcount ratio, poverty gap and squared poverty gap); weighted inequality index (i.e., Watts Index, Gini Index and MLD Index) and average monthly per capita income in the designated 138 countries according to World Bank’s classification over a period of 2005–2010. The data set mainly contain countries’ unit record household survey at least one which is conducted between the countries during the sample period. The regression model encompassing the impact of economic growth and income inequality on poverty reflects that income inequality increases poverty while economic growth decreases poverty. It indicates that the impact of inequality in increasing poverty is a somewhat greater than that of growth in average income in reducing overall poverty in a sample countries. The other regression model encompassing the impact of economic growth and poverty on income inequality showed that the poverty itself is also likely to be a barrier for poverty reduction; and inequality seems to predict lower future growth rates. The final regression model depicting the impact of poverty and income inequality on mean income of the household suggests that poverty itself reduces mean income of the household while income inequality increases economic growth. The results are interesting and simply suggest that whenever social institutions malfunction, the incidence of damage would usually be distributed unevenly over the society’s members.

Informality in developing economies: Regulation and fiscal policies

This paper proposes a unified theoretical framework where formal and informal firms coexist and face the same type of product and labor market imperfections: they have monopoly power in the goods market, they are subject to matching frictions in the labor market, and wages are determined by bargaining between large firms and their workers, through either individual or collective bargaining. Our model matches the main stylized facts on informality for developing countries and appears to be a good candidate for policy analysis. In this framework, we study the impact on informality, wages and unemployment of policies that may be used to reduce informality. We consider changes in product market regulation (PMR) and in two types of fiscal policies, labor taxes and formality enforcement. We find that lessening PMR decreases informality and unemployment simultaneously, indicating that there is not necessarily a tradeoff between informality and unemployment. The tradeoff appears when fiscal policies are used, though. Moreover, the impacts of PMR on unemployment and on wages are larger under collective than individual bargaining. With respect to wage inequality, lessening PMR reduces it, while lower taxes tend to increase the formal sector wage premium.     

An Empirical Analysis of the Impact of Government Tax and Auditing Policies on the Size of the Underground Economy:

.
This study empirically examines the impact of federal income tax rates, IRS penalties on unpaid tax liabilities, and audit rates of the Internal Revenue Service on the size of the underground economy in the United States, Recent data generated by Edgar Feige are used to measure the size of the underground economy. Based on ordinary least squares estimates, it is found that the maximum marginal personal income tax rate raises the size of the underground economy. In addition, the size of the underground economy is found to be a decreasing function of both the percentage of tax returns audited and the penalties imposed by the IRS on unpaid taxes.     

Regional Wage Gaps,Education and Informality in an Emerging Country: The Case of Colombia

This paper uses Colombian micro-data to analyze the role of education and informality in regional wage differentials. The hypothesis is that apart from differences in the endowment of human capital, regional heterogeneity in the incidence of informality is another important source of regional wage inequality in emerging countries. This is confirmed by the evidence from Colombia, which also reveals remarkable spatial heterogeneity in the wage return to individuals’ characteristics. Regional heterogeneity in returns to education is especially intense in the upper part of the wage distribution. In turn, heterogeneity in the informal pay penalty is more relevant at the bottom.     

IFRS,financial development and income inequality: An empirical study using mediation analysis

Income inequality continues to be an issue of concern. Early work on economic development suggested that, as a country’s economy grows, incomes would rise and reduce any income disparities. However, there is growing evidence that as countries develop, income inequality actually worsens. Some studies argue that this is the result of financial development and the growth of the financial sector. Although there is a good deal of empirical research on the relationship between financial development and income inequality, there is no prior work that examines how accounting standards, in particular International Financial Reporting Standards (IFRS), might influence this relationship. This study examines the relationship of IFRS and financial development with income inequality using mediation analysis over the period from 1998 to 2018. The results indicate that the impact of IFRS on income inequality is mediated by financial development. Moreover, there is a direct relationship between IFRS and inequality.     

Understanding the determinants of crime

In this paper, we use an overlapping generations model where individuals are allowed to engage in both legitimate market activities and criminal behavior in order to assess the role of certain factors on the property crime rate. In particular, we investigate if differences in the unemployment rate, fraction of low human capital individuals in an economy, apprehension probability, duration of a jail sentence, and income inequality could be capable of generating large differences in crime rates that are observed across countries. We find that small differences in the apprehension probability and income inequality can generate quantitatively significant differences in the crime rates across similar environments.     

New and Current Evidence on Determinants of Aggregate Federal Personal Income Tax Evasion in the United States

Using the most current data available, this study seeks to identify any new as well as traditional determinants of personal income tax evasion. A variety of empirical estimates find that income tax rates, the IRS audit rate and IRS penalty interest rates, and the unemployment rate all influence tax evasion. In addition, rarely investigated variables including the tax‐free interest rate, the public's job approval rating of the president, and the public's dissatisfaction with government, along with previously unstudied variables, namely, the real interest rate yield on Moody's Baa‐rated long‐term corporate bonds and the real interest rate yield on three‐year Treasury notes, also affect income tax evasion.

The distributional implications of tax and transfer programs in US

The distributional consequences of changes in tax laws and transfer programs in the United States are studied. Using detailed household income data from the Panel Study of Income Dynamics (PSID) from 1981–91, income inequality is measured for both pretax/transfer and post-tax/transfer definitions of household income. A new statistical methodology for assessing the impact of changes in taxes and transfers on the size distribution of income is utilized. Confidence intervals are constructed for various measures of inequality, and hypothesis tests are conducted to determine whether observed changes in the distribution of income due to taxes and transfers are statistically significant. Using decomposable measures of inequality, the implications of type of tax table used are investigated.     

Does GINI respond to income volatility in an asymmetric manner? Evidence from 41 countries

Previous studies that assessed the impact of income volatility (as a measure of economic uncertainty) on income inequality relied upon either cross-sectional data or panel data, mostly due to the lack of sufficient time-series observations. Now that enough time-series observations are available for many countries, we revisit the issue and assess the possible asymmetric effects of income volatility on income inequality in each of the 41 countries. We find short-run asymmetric effects in almost all countries, short-run impact asymmetric effects in 20 countries, and long-run asymmetric effects in 21 countries. There was much less support when we engaged only in symmetric analysis.     

The heterogeneous impact of taxation on economic development: New insights from a panel cointegration approach

In this paper, we study the role of taxation on long-run income performance. In the theoretical part of the study, we develop a stylized model based on Barro (1990), in which income taxation has two contradictory roles in the standard Solow (1956) setup: on the one hand, taxation appropriates resources that would otherwise be used for physical capital accumulation, and on the other, it is the source of government spending, which is used to support private production. In the empirical part of the study, the impact of consumption tax, personal income tax, corporate profit tax and property tax on income is estimated using the common correlated effects (CCE) panel cointegration approach, which allows for cross-sectional dependencies and provides both panel- and country-specific results. The panel findings for 30 OECD countries for the period of 1995–2016 indicate that only consumption tax has a statistically significant negative effect on long-run income. However, because the type and sign of the tax coefficients are heterogeneous for the country-specific results, we conclude that taxation has heterogeneous effects on income.     

The long run effects of changes in tax progressivity

This paper compares the steady-state outcomes of revenue-neutral changes to the progressivity of the tax schedule. Our economy features heterogeneous households who differ in their preferences and permanent labor productivities, but it does not have idiosyncratic risk. We find that increases in the progressivity of the tax schedule are associated with long-run distributions with greater aggregate income, wealth, and labor input. Average hours generally declines as the tax schedule becomes more progressive implying that the economy substitutes away from less-productive workers toward more-productive workers. Finally, as progressivity increases, income inequality is reduced and wealth inequality rises. Many of these results are qualitatively different than those found in models with idiosyncratic risk, and therefore suggest closer attention should be paid to modeling the insurance opportunities of households.
