Income taxes and the income velocity of money: An empirical analysis

From 1981iv to 1983ii, the growth rate of the income velocity of money declined sharoly. Almost all forecasts of this rate based on standard models overpredicted the velocity growth rate over this period. In this paper it is argued that income taxes exert a direct and discernible influence on velocity of money which has not been recognized by these models. As a result, most models failed to capture the 1981–1983 Reagan tax cuts and, consequently, overpredicted the velocity growth rate in this period. It is shown that the tax-velocity hypothesis is supported by the results of an empirical test. It is also shown that the inclusion of taxes in a model of velocity helps alleviate the overprediction of the velocity growth rate in the 1981–1983 period.     

Which commodity taxes should supplement the income tax?

The analysis takes as its point of departure a continuum of consumers economy in which an optimum income tax exists and is the only tax instrument in operation. The welfare effects of introducing small excise taxes to supplement the income tax are then explored. Essential in this context are changes in the tax distortions of work incentives. It is shown that a commodity should be taxed or subsidized depending on whether it is positively or negatively related to leisure in a sense which is precisely defined. The results are related to earlier contributions to the literature on direct versus indirect taxation.     

A spatial analysis of provincial corporate income tax responses: evidence from Canada

Abstract.  Using a model of interdependent tax choices, and accounting for equalization entitlements and general transfers, this paper estimates – making use of a spatial econometric framework – corporate income tax-setting functions for all Canadian provincial governments. The results show that there is a statistically significant positive fiscal interaction among a subset of provinces and between all provinces and the federal government. Provincial corporate income taxes are also found to be negatively related to equalization entitlements, general federal transfers, and the federal corporate income tax. A robustness check on the fiscal relationship between Ontario and Quebec verifies the existence of significant bi-directional fiscal interdependencies. The paper also introduces U.S state corporate income taxes as covariates and examines their interaction with Canadian provinces.     

The incidence of income taxes on high earners in Canada

This article explores the “brain drain” explanation for the concentration of incomes in Canada during the past 30 years, namely, that high-skilled Canadians make use of high salaries on offer in the United States to extract higher salaries at home. If this is the case, then for a given level of US salaries, the threat to accept outside offers should be more credible when the Canadian dollar is depreciating against the US dollar, and weaker when the Canadian dollar is appreciating. The data are broadly consistent with this claim: income concentration worsened during the depreciations of the 1980s and 1990s, and eased when the Canadian dollar began to appreciate in value. The article develops a simple two-parameter model based on the propositions that high earners in Canada can use US salaries to bargain for higher salaries, and that Canadian high earners can shelter part of their income from personal income taxes. It also offers some preliminary evidence about the parameter values consistent with available data. The results suggest that higher top marginal personal income tax rates may potentially accentuate top-end after-tax income inequality. If high earners are able to use their bargaining power to extract pay increases to offset higher tax rates, then the burden of increased personal income taxes will be deflected elsewhere, and may even have the perverse effect of making the after-tax income distribution more unequal than it was before.     

Assessing tax reforms through the elasticity of reported income: an empirical analysis for Spain

This paper demonstrates the usefulness of the elasticity of reported income to assess tax reforms from the perspectives of tax revenue and well-being. Employing different identification strategies, evidence is provided of the value of the elasticity of gross reported income in Spain and, based on this elasticity, a detailed assessment is made of the impact of the increase in marginal tax rates which the Spanish government approved in 2012. We use microdata from the Taxpayers Panel of the Institute for Fiscal Studies. The mean value of this elasticity for Spain is 0,363 with considerable heterogeneity depending on taxpayers’ characteristics.     

Revenue-maximizing tax rates in personal income taxation in the presence of consumption taxes: a note

This article computes revenue-maximizing tax rates in personal income taxes in the presence of consumption taxes. It finds that the traditional Laffer analysis, which neglects the effects of marginal tax rates on consumption, overestimates the magnitude of revenue-maximizing tax rates. The bias caused by this oversight is computed.     

Agency problems and unrelated business income of non-profit organizations: an empirical analysis

Nonprofit organizations are traditionally assumed to dislike commercial activities. In the USA, they are however allowed to engage in commercial activities, but the income they derive from these activities is then subject to the so-called ‘unrelated business income tax’. If NPOs do indeed dislike commercial income, then why do they engage in these activities? Using a data set of 2103 US NPOs, this study suggests that the presence of agency problems inside the organization can at least provide an explanation for the occurrence of ‘unrelated business income’.     

Information sharing for consumption tax purposes: An empirical analysis

The paper studies the determinants of information sharing between Swedish tax authorities and 14 EU tax authorities for value-added tax (VAT) purposes. It is shown that trade-related variables (such as the partner country’s net trade position and population size), reciprocity, and legal arrangements are significant determinants of Sweden’s trade in tax information. Countries that are net exporters of goods to Sweden appear to be net importers of information from Sweden, reflecting their need for information to combat export-related VAT fraud. Reciprocity plays a more important role in Sweden’s export of information upon official request than in its spontaneous export of information.     

房产税与投机泡沫——基于天津的实证研究

The main purpose of this paper is to identify and measure the potential effect of property tax on speculative bubble in residential property market in China where the issue on the introduction of property tax is still fiercely debated. As a primary and necessary step, we firstly provide an empirical analysis on housing price dynamics of Tianjin. Moreover, this paper proposes a method to identify and measure the potential effect of property tax on speculative bubble in housing market. To capture the actual influence of property tax, we divide the effect into short-term one and long-term one and measure them respectively based on the information provided by estimation result of housing price structure.      

An empirical analysis of income disparity and consumption in China

Using China’s provincial data from 1991 to 2005, this paper analyzes the impact of urban income disparity on their consumption based on static and dynamic panel data models and state space model. The GMM and Kalman Filter methods are used in the estimation and the variables such as income and price are controlled. The empirical results show that the elasticity of permanent income to consumption is much higher than that of temporary income; and the impact of income disparity on consumption is negative and substantial. A rise of 0.01 in the absolute value of Gini coefficient will cause a reduction of 0.35% in consumption on average. The effects fluctuate with the change of economic structure, consumption expectation and economic cycle. In the beginning years of 1990s, it is positive to enlarge income disparity moderately for consumption. It is the year of 1996 that the negative effect first appears in China. During 1998–2004, an increase of 0.01 to the absolute value of Gini coefficient will result in the reduction of consumption to fluctuate between 0.37% and 0.54%. In order to enlarge domestic demand and promote consumption, the focus should be the improvement of permanent income instead of temporary income, and the vigorous policies to reduce income disparity.     

Housing decisions and the U.S. income tax: An econometric analysis

This paper examines the effects of the current income tax treatment of owner-occupied housing on the quantity of housing consumed and on the tenure choice by various groups. Cross-sectional data for 1970 are used to estimate jointly tenure choice and housing demand equations. The equations' parameters are used to assess the efficiency and equity implications of the relevant tax law provisions.     

The effect of marginal tax rates on taxable income: a panel study of the 1988 tax flattening in Canada

Federal tax reform in 1988 flattened the Canadian personal income tax schedule, changing the marginal tax rates for many individuals. Using methods similar to those applied by Auten and Carroll [Rev. Econ. 81(4) (1999) 681] in the study of the effects of the 1986 U.S. Tax Reform Act, we estimate the responsiveness of income to changes in taxes to be substantially smaller in Canada. However we find evidence of a much higher response in self-employment income, in the labor income of seniors and from those with high incomes.     

Lagged reactions in short-run estimates of tax shifting of company income and sales taxes in Kenya

The aim is to provide some insights into the short-run dynamics of tax shifting. Using Kenyan cross-section data on firms for 1974 and 1975, estimates are made of current and lagged shifting for both the company income and sales taxes. One of the findings is that the income tax is over-fully shifted. Because this outcome regularly occurs in the empirical literature of tax shifting, the main theoretical effort of the paper is devoted to explaining this result. A Williamson-type model is developed which attributes any excess of 100% shifting to reductions in managerial slack that accompany increases in the income tax.     

The optimal linear income tax: A diagrammatic analysis

This paper clarifies the role of the tax possibility frontier and the social indifference curve in the comparative statics analysis of the optimal linear income tax. By a mostly diagrammatic derivation of the results we confirm the conventional conjecture that the optimal marginal tax rate increases with the government's inequality aversion. On the other hand, we cannot always confirm analytically the conventional conjecture that the optimal marginal tax rate increases with the government's budgetary needs.     

The contractionary effects of tax shocks on productivity: An empirical and theoretical analysis

I analyze the effects of tax policy changes on US Total Factor Productivity. VAR estimates show that permanent and exogenous tax increases have strong, permanent, and negative effects on TFP which represent about 80% of change in output following the tax increase. I then build a DSGE model which has learning-by-doing and endogenous TFP evolution. The benchmark model is able to replicate the empirical impulse responses. However, when I calibrate the model as in the literature, the effect of taxes on TFP is substantially less elastic than in the data. I argue that this divergence may arise because tax changes labeled as exogenous can give spurious results or because of a mis-specified model.     

Nature of transfers,income tax function and empirical estimation of elasticity of taxable income for Brazil

This article aims to estimate the elasticity of taxable income (ETI), taking into account the nature of transfers and their use as a redistribution package (involving cash and in-kind transfers) to households in Brazil. Our contributions are twofold. First, we provide a simple model with balanced-budget government that reveals the role played by cash and in-kind transfers on the labour supply (and income tax revenues thereof). Next, in order to estimate ETI in the presence of cash and in-kind transfers, Brazilian population surveys (Pesquisa Nacional por Amostra de Domicílios [PNAD]) are used to explore a limited tax reform that was implemented between 1997 and 1998. This reform only affected the higher income tax bracket. Our findings suggest that in-kind (cash) transfers are positively (negatively) associated with reported taxable income and precise estimation of ETI requires estimates of both types of transfers. Last, we estimate the ETI for Brazil in the range from 0.4 to 1.3 not different from those that maximize income tax revenues.     

The transmission of inflation between the United States and Canada: An empirical analysis

This paper investigates the causal patterns, in the sense of Granger, which characterize the relationships between U.S. and Canadian inflation rates under different exchange rate regimes. Both bivariate and multivariate models are considered. The results suggest that the flexible exchange rate period of the 1950s exhibits no insulating effects with causal inferences similar to those from the fixed rate era of the 1960s. For the flexible rate period of the 1970s the bivariate model indicates that U.S. and Canadian inflation are independent but when the model is expanded to include money growth rates in each country, evidence of a direct, nonmonetary causal link from U.S. inflation to Canadian inflation is found.     

Vertical versus horizontal tax externalities: An empirical test

We study taxation externalities in federations of benevolent governments. Where different hierarchical government levels tax the same base, one can observe two types of externalities: a horizontal externality, working among governments of the same level and leading to tax rates that are too low compared to the social optimum; and a vertical externality, working between different levels of government and leading to suboptimally high tax rates. Building on the model of Keen and Kotsogiannis [Keen, Michael J., Kotsogiannis, Christos, 2002. Does federalism lead to excessively high taxes? American Economic Review 92 (1) 363–370], we derive a discriminating hypothesis to distinguish vertical and horizontal tax externalities based on measurable variables. This test is applied to a panel data set on local taxes in a sample of Swiss municipalities that feature direct-democratic fiscal decision making, so as to maximize the correspondence with the “benevolent” governments of the theory. We find that vertical externalities dominate – they are thus an observed empirical phenomenon as well as a notable extension to the theory of tax competition.     

The impact of the Indonesian income tax reform: A CGE analysis

This study evaluates the impacts of Indonesia's recent income tax reforms on key macroeconomic variables, as well as the impacts on poverty and income distribution. It was found that the reductions in personal income tax and corporate income tax increase economic growth under a balanced budget assumption. The policy reforms also lead to a small reduction in the incidence of poverty. However, the policies also lead to an increase in income inequality because the tax cut is more beneficial to households in the highest income categories. It is recommended that future tax cuts should target the urban and rural poor.     

An empirical analysis of the Nuclear Liability Act (1970) in Canada

The Nuclear Liability Act (1970) limits the liability of nuclear reactor operators in Canada to the first $75 m of any off-site damage done by an accident. In recent litigation, the limitation has been challenged. It has been argued that the implicit subsidy which such a provision confers encourages the use of nuclear over other fuel sources and reduces safety incentives. During the litigation, it was contended that the value of the subsidy could be as high as 12 to 16 cents per kW h. We use numerical curve-fitting techniques to evaluate the subsidy using data implicit in insurance premiums and under a range of expert assessments regarding `worst case' scenarios. In most cases, the subsidy is found to be less than 1 cent per kW h, and in no case is it greater than 4 cents. While the uninternalised costs are not trivial they are smaller than existing estimates of those associated with the use of alternative fuels.
