Optimal top marginal tax rates under income splitting for couples

This paper provides formulas for optimal top marginal tax rates when couples are taxed according to income splitting between spouses, consumption is taxed, and the skill distribution is unbounded. Optimal top marginal income tax rates are computed for Germany using a dataset that includes the tax returns of all German top taxpayers. We find that the optimal top marginal tax rate converges to about 2/3 and convergence obtains at income levels that are substantially higher than those currently subject to the actual top tax rate.     

Hourly wage rate and taxable labor income responsiveness to changes in marginal tax rates

Recently, a voluminous literature estimating the taxable income elasticity has emerged as an important field in empirical public economics. However, to a large extent it is still unknown how the hourly wage rate, an important component of taxable income, reacts to changes in marginal tax rates. In this study we use a rich panel data set and a sequence of tax reforms that took place in Sweden during the 1980s to estimate the elasticity of the hourly wage rate as well as the taxable labor income elasticity with respect to the net-of-tax rate. We also estimate elasticities with respect to the non-labor income in a way that is novel in the literature. While carefully accounting for the endogeneity of marginal tax rates we find a statistically significant response in wage rates both among married men and women. The estimates of the hourly wage rate elasticity with respect to the net-of-tax rate fall in the range of 0.14–0.16 for males and 0.41–0.57 for females, whereas the corresponding taxable labor income elasticity estimates hover between 0.19–0.21 for males and 0.96–1.44 for women. Moreover, for men we find that the taxable labor income elasticity with respect to non-labor income is statistically significant; the point estimate being ? 0.07. This implies that the compensated taxable labor income elasticity is about 5 percentage points higher than the uncompensated one. In general, we consider the estimates for males to be more certain and robust than the estimates for females.     

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.     

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.     

Average marginal tax rates in the UK economy

Using a known methodology, this paper calculates the average tax rate (ATR) and three different average marginal tax rate (AMTR) measures for the UK. The three different AMTR measures are greater than the ATR in the same year because of the progressive tax system in the UK. Barro's AMTR measure weighted by total income is greater than Barro's AMTR measure weighted by number of returns because of the unequal distribution of income, and Barro's AMTR measure weighted by total income exceeds Seater's AMTR measure because total income before tax in Seater's AMTR measure is greater than total income after tax in Barro's AMTR measure.     

Impact of income tax on happiness: evidence from the United States

The present work considers the level of demonstrated happiness and unhappiness within groups, the latter measured by the conditional probability of suicide within groups facing an income tax rate and those without. Using US data for the year 2004, our results show that individuals have lower rates of suicide or are ‘happy’ when they do not pay income taxes than those who pay.     

The impact of the corporate income tax: evidence from state organizational form data

By taxing the income of corporate firms at a different rate than non-corporate firms, taxes can play an important role in a firm's choice of organizational form. The sensitivity of the organizational form decision to tax rates provides a key indicator of the distortion created by the corporate income tax. This paper uses new cross-sectional data on organizational form choices across states compiled in the Census of Retail Trade to estimate this sensitivity. The results document a significant impact of the relative taxation of corporate to personal income on the share of real economic activity that is done by corporations and that the impact is many times larger than has been found in the previous empirical literature based on time-series data. The results show little impact, however, on the actual operations of firms such as their labor intensity, wages and the like. They do indicate that firms are able to exploit the progressivity of the corporate income tax system by dividing into numerous firms.     

The uniform enterprise income tax reform in China

In China, the income tax of enterprise is very different between foreign funded enterprises and other domestic enterprises. It is believed that this discrimination is harmful to the entire economy. So there is a reform in the tax system to build a uniform enterprise income tax. This is a significant reform in China＇s tax system, so every decision about this have to count the cost and the benefit carefully. The author has introduced the Computable General Equilibrium （CGE） to simulate this new tax system and value its benefit and cost. There are two different models in the paper; they are of different assumptions and for different purposes. Model I is a static CGE model and model II is a Ramsey Dynamic model. The static model is mainly used for comparative static approach to examine how the tax reform will change the endogenous variables. According to the results of the model, more goods will be produced by both of the DFEs and FIEs after the tax reform in the medium and low tax effective tax rate situations. If the nominal tax rates decrease 24.24% （from 33% to 25%）, the enterprise income tax will only reduce 19.36% and the total tax revenue will only reduce 1.911%. The dynamic model will concentrate on the costs and benefits during the transition. From the results of the model, a lower tax rate will increase the level of investment, capital stock, capital prices, wage rate and also the growth rates through transition. If the capital tax rates are changed gradually, the fluctuating of transition will be smoothed a little.

Crime rates,male youth unemployment and real income in Australia: evidence from Granger causality tests

This article applies Granger causality tests to examine the relationship between seven different categories of property crime and violent crime against the person, male youth unemployment and real male average weekly earnings in Australia from 1964 to 2001 within a cointegration and vector error correction framework. It is found that fraud, homicide and motor vehicle theft are cointegrated with male youth unemployment and real male average weekly earnings. However, there is no evidence of a long-run relationship between either break and enter, robbery, serious assault or stealing with male youth unemployment and real male average weekly earnings.     

Habit persistence in effective tax rates

This paper uses administrative data from the Australian Tax Office (ATO) to model the effective tax rates (ETRs) of large Australian corporates. The extent to which there is any habit persistence in ETRs is also examined. The results suggest that unobserved entity heterogeneity is important in explaining ETRs. In terms of observed heterogeneity, entity size, level of leverage, capital intensity, foreign income and R&D, are important explanators of ETRs. There is also evidence of a significant amount of habit persistence, implying that ETRs converge monotonically towards the statutory rate of corporation tax.     

Accounting for the family in European income tax systems

Tax systems are expected to achieve many things at once andthis paper discusses the trade-offs involved in attempting toreconcile conflicting aims. It surveys the various instrumentsthat are used to take account of marriage and the presence ofchildren and describes the current systems in the 15 EuropeanUnion countries. The impact of alternative tax treatments ofthe family 'borrowed' from other countries is examined for theUK, using the tax-benefit microsimulation model, POLIMOD. Thepaper explores the implications of the alternatives for thetax paid by families of different types and for the work incentivesof individuals in different family situations.     

Notes and comments. Ricardo on income tax: a note

Despite the fact that Ricardo experienced Pitt's income taxpolicies, and that he regarded taxation as the most importantissue to which the principles of political economy should beapplied, he rarely referred to actual tax reforms. This paperindicates that Ricardo's system of economics cannot bring aboutany tax that is completely compatible with his main criteriafor taxation (distribution neutrality, price neutrality andminimum taxation) as well as certainty, convenience and thesecurity of property. This result may explain why Ricardo didnot say which type of taxation system the British governmentshould establish.     

Taxation and income distribution: The Colombian tax reform of 1974

In late 1974 the Government of Colombia implemented a major tax reform package embracing virtually all aspects of the revenue system. The reform was designed to serve allocative and stabilization as well as redistributive goals. This paper focuses upon the likely impact of the 1974 tax measures upon income distribution. Section 2 describes the prevailing distribution of income prior to the reform. Section 3 presents a short outline of the principal features of the 1974 package, and sections 4 through 6 provide an evaluation of its redistributive effects. The authors conclude that the initial impact of the reform was undoubtedly progressive, as it likely served to shift as much as 1.5 percent of GDP away from the top quintile of the income distribution.     

Another look at the spending response to the 2001 income tax rebates

This article revisits the spending response to the 2001 US tax rebates by focussing on two key aspects of how tax policy researchers use the Consumer Expenditure Survey (CEX). These two attributes, which are often overlooked, are as follows: the measures used for consumption and the ‘outlier’ criteria applied to the data. First, I reproduce the results in Johnson et al. (2006 Johnson, DS, Parker, JA and Souleles, NS. 2006. Household expenditure and the income tax rebates of 2001. American Economic Review, 96: 1589–610. [Crossref], [Web of Science ®] , [Google Scholar]), which (using the CEX) concluded that households immediately spent 20–40% of their rebates on nondurable consumption goods. Then, I show how making two changes – both of which are relied upon in the literature – affects their results. These adjustments reduce the estimated magnitude of the rebate's impact by as much as 100%.     

The marginal cost of public funds and tax reform in Africa

In this paper we propose estimates of the marginal cost of public funds (MCF) in 38 African countries. We develop a simple general equilibrium model that can handle taxes on five major tax classes, and can be calibrated with little more than national accounts data. A key feature of our model is the explicit recognition of the informal economy. Our base case estimate of the average MCF from marginal increases in all five tax instruments is 1.2. Focusing on the lowest cost tax instruments in each country, commonly the VAT but not always, the average MCF is 1.1. Finally extending the tax base to include sections of the informal economy by removing some tax exemptions offers the potential for a low MCF source of public funds, and a lowering of MCFs on other tax instruments.     

A note on the marginal tax rate in a finite economy

The marginal tax rate is shown to be non-negative in Guesnerie and Seade's model of nonlinear pricing in a finite economy under assumptions that are as mild as those customarily adopted in nonlinear tax models with a one-dimensional continuum population.     

The permanent income hypothesis in underdeveloped economies:: Additional evidence

Laumas and Laumas find no support for the permanent income hypothesis in recent work on a consumption function for India. However, permanent income has been used not only in consumption but also in demand for money functions. Estimates of demand for money in 10 Asian LDCs indicate that substitution of permanent for current income is warranted. In particular, the estimate for India is improved substantially by the use of permanent instead of current income. Furthermore, the weights obtained from a polynomial lag distribution are almost identical to the Laumas' exponential weights with which they construct permanent income.     

Modelling aggregate personal income tax revenue in multi-schedular and multi-regional structures

This paper derives analytical expressions for aggregate personal income tax revenue obtained from a multi-schedular and multi-regional personal income tax system, with revenue divided among central and regional governments. Aggregate income tax revenue is expressed as a function of characteristics of the distribution of taxable income, making it possible to identify the sources of revenue differences among regions. The approach is applied to the tax structure in Spain, and the effects of income distribution differences among the Spanish regions are examined.     

On measuring violations of the progressive principle in income tax systems

Kakwani and Lambert (Eur J Polit Econ 14(2):369–380, 1998) state three axioms which should be respected by an equitable tax system. Using the Atkinson–Plotnick–Kakwani re-ranking indexes of taxes, tax rates, and post-tax incomes, calculated with respect to the ranking of pre-tax income distribution, they then propose a measurement system to evaluate the negative influences that axiom violations exert on the redistributive effect of taxes. In this paper, we reconsider the way Kakwani and Lambert measure violations of their second axiom, which concerns the re-ranking of tax rates. We construct a non-negative index which is strictly faithful to Kakwani and Lambert’s commands; we show that the Authors’ measure does not exactly fit the statements made in their second axiom. Both Kakwani and Lambert’s original measurement system and the modified one are then applied to Italian personal income tax in 2008. According to the modified measurement system, the average tax rate seems to play a smaller role than that suggested by the results gained using Kakwani and Lambert’s original methodology.
