The Evolution of the Tax Structure of a Reforming Transitional Economy: Hungary 1988–98

The paper analyses the revenue-raising, distributional and incentive effects of the personal tax system in Hungary from the start of the transitional tax reforms of 1988 to 1998, and shows that the tax structure has converged to an almost linear form similar to the more heavily taxed EU countries. The 1998 pension reform has reversed a trend increase in average and marginal tax rates but marginal rates still appear too high for a country wishing to encourage growth and employment creation.     

Indirect tax reform and the role of exemptions

This paper examines the question of whether indirect tax rates should be uniform, using four different modelling strategies. First, marginal tax reform is examined. This is concerned with the optimal direction of small changes in effective indirect tax rates and requires considerably less information than the calculation of optimal rates. Second, the welfare effects of a partial shift from the current indirect tax system in Australia towards a goods and services tax (GST) are considered, with particular emphasis on differences between household types and the role of exemptions. Third, in view of the stress on a distributional role for exemptions of certain goods from a GST, the potential limits to such redistribution are considered. The fourth approach examines the extent of horizontal inequity and reranking that can arise when there are non‐uniform tax rates. These inequities arise essentially because of preference heterogeneity.     

Redistributive effects of the shift from personal income taxes to indirect taxes: Belgium 1988–93

Between 1988 and 1993, the Belgian personal income tax system and the indirect tax system were reformed to a considerable extent. We use microsimulation models to investigate the impact of the reform on the liability progression and the redistributive effect of the combined tax system. The redistributive effect of personal income taxes decreased, notwithstanding an increase in liability progression. For indirect taxes, both the liability regressivity and the reverse redistributive effect have been enhanced. We use recently developed statistical tests to gauge the significance of the observed changes.     

Changes in Income Distributions and the Role of Tax‐Benefit Policy During the Great Recession: An International Perspective

In this paper, we examine the impact of the economic crisis and the policy reaction on inequality and relative poverty in four European countries: France, Germany, Ireland and the UK. The period examined, 2008–13, was one of great economic turmoil, yet it is unclear whether changes in inequality and poverty rates over this time period were mainly driven by changes in market income distributions or by tax‐benefit policy reforms. We disentangle these effects by producing counterfactual (‘no reform') scenarios using tax‐benefit microsimulation and representative household surveys for each country. For the first stage of the Great Recession, we find that the policy reaction contributed to stabilising or even decreasing inequality and relative poverty in the UK, France and, especially, Ireland. Market income changes nonetheless pushed up inequality and relative poverty in France. Relative poverty increased in Germany as a result of policy responses combined with market income changes. Subsequent policy reforms, in the later stage of the crisis, had markedly different cross‐country effects, decreasing overall poverty in France, increasing it in Ireland, and giving mixed effects for different subgroups in Germany and the UK.     

Pro-poor indirect tax reforms,with an application to Mexico

This paper proposes a methodology for testing for whether tax reforms are pro-poor. This is done by extending stochastic dominance techniques to identify tax reforms that will be deemed absolutely or relatively pro-poor by a wide spectrum of poverty analysts. The statistical properties of the various estimators are also derived in order to make the method implementable using survey data. The methodology is used to assess the pro-poorness of possible reforms to Mexico’s indirect tax system. This leads to the identification of several possible pro-poor tax reforms in that country. It also shows how the pro-poorness of a tax reform depends on one’s conception of poverty as well as on the revenue and efficiency impact of the reform.     

Decomposition analysis of distributive policies using behavioural simulations

For policy makers and analysts, it is important to isolate the redistributive impact of tax-benefit reforms from changes in the environment in which policies operate. When actual reforms are motivated by work incentives, it is also crucial to evaluate behavioural responses and the distributional consequences thereof. For that purpose, I embed counterfactual simulations in a formal decomposition framework to quantify the relative roles of (i)?direct tax-benefit policy changes, (ii)?indirect policy effects due to labour supply responses to the reforms and (iii)?all other factors affecting income distribution over time. An application to the UK shows that the redistributive reforms of the 1998–2001 period have offset much of the rise in market income inequality and contributed to a strong decline in child poverty and poverty amongst single parent households. In the latter group, a third of the headcount poverty reduction (and half of the reduction in the depth of poverty) is on account of the very large incentive effect of the policy changes.     

Indirect Taxation in Greece: Evaluation and Possible Reform

The paper assesses the distributional and efficiency/disincentive aspects of the Greek indirect tax system, which provides 60% of total tax revenue. The marginal welfare costs of broad commodity groups were computed to identify welfare-improving directions of reform. The disincentive effects were estimated from marginal indirect tax rates using Household Expenditure Survey data. The indirect tax structure is shown to be unnecessarily complicated and inefficient, without achieving any redistributive goals. The UK indirect tax structure was shown to be simpler, more equitable and more efficient to implement and administer when simulated on Greek consumers.     

Long‐Term Effects of Fiscal Policy on the Size and Distribution of the Pie in the UK*

This paper provides a joint analysis of the output and distributional long‐term effects of various fiscal policies in the UK, using a vector autoregression (VAR) approach. Our findings suggest that the long‐term impact on GDP of increasing public spending and taxes is negative, and especially strong in the case of current expenditure. We also find significant distributional effects associated with fiscal policies, indicating that an increase in public spending reduces inequality while a rise in indirect taxes increases income inequality.     

Incomes,Incentives and the Growth of Means-Testing in Hungary

The purpose of this paper is to examine the reform of family benefits and the growth of means-testing in Hungary. From 1996, many family benefits were means-tested for the first time. A new microsimulation model for Hungary, running on recent survey microdata, is used to simulate the impact of the 1996 reforms on government expenditures, the distribution of incomes, the targeting of benefits and effective marginal tax rates. These reforms are found to be largely benign and even progressive, but they also appear to be paving the way for the further extension of means-testing. The model is used to investigate such an extension by simulating the impact of a UK-style system of means-tested family benefits in Hungary. This system achieves some expenditure savings and better targeting of benefits, but also greatly increases effective marginal tax rates on low-income households with children. The paper argues that resulting poverty traps may increase child poverty in Hungary in the longer term and cautions against the overextension of means-testing.     

Targeting welfare in Italy: old problems and perspectives on reform

This paper has two principal objectives. Using a tax‐benefit microsimulation model and the 1998 micro data of the Bank of Italy survey of household income and wealth, we first study the distributional effects of the current Italian income maintenance system and highlight its main defects and limitations, concerning in particular its unequal coverage of the population and its low efficiency in fighting poverty. The second aim is to describe and analyse the reforms recently implemented in this field; in particular, the Italian government has reformed the targeting criteria and introduced three new cash transfers. We describe these reforms both in their institutional characteristics and in their likely distributional consequences, and examine whether and to what extent they are able to overcome the shortcomings of the current system.     

Tax Amnesties and Income Tax Compliance: The Case of Spain

The aim of this paper is to evaluate the long‐term impact on Spanish individual income tax (IRPF) compliance of the amnesty measures granted in 1991 within the framework of the 1988–91 income tax reform programme. To that end, we combine time‐series techniques with outlier detection methods and the Bai and Perron (1998) test for the endogenous estimation of structural breaks. On the basis of the analysis of the monthly IRPF tax collection series from 1979 to 1998, we find that the amnesty had no effect on tax collection in either the short or the long term. By contrast, we find evidence of the permanent positive impact caused by the legislative and administrative measures linked to the IRPF reform process begun in 1988.     

Public Pension Reform in the United Kingdom: What Effect on the Financial Well‐Being of Current and Future Pensioners?*

Unlike many tax and benefit changes, reforms to public pension programmes take many years to have their full effect. This paper examines the effect of reforms to the public pension programme in the United Kingdom on the state retirement incomes of current generations of pensioners and on the prospective state incomes of future generations of pensioners. We show that, for an individual with lifetime earnings close to male average earnings, the UK pension system is at its most generous to those reaching the state pension age around the year 2000, but that the introduction of the state second pension and the pension credit postpones this peak for individuals on lower incomes and for those with substantial periods out of paid employment spent with caring responsibilities. We also consider how the ‘mix’ of benefits, particularly between the contributory and income‐tested sectors, could change over time, and the impact that this would have on incentives to save for retirement.     

The Stability of Tax Elasticities over the Business Cycle in European Countries

We estimate short‐ and long‐run tax elasticities that capture the relationship between changes in national income and tax revenue. We show that the short‐run tax elasticity changes according to the business cycle. We estimate a two‐state Markov‐switching regression on a novel data set of tax policy reforms in 15 European countries from 1980 to 2013, showing that the elasticities during booms and recessions are statistically (and often economically) different. The elasticities of personal income taxes, corporate income taxes, indirect taxes and social contributions tend to be larger during recessions. Estimates of long‐run elasticities are in line with existing literature.     

Reduced Tax Progressivity in Norway in the Nineties: The Effect from Tax Changes

The inequality in pre-tax income increased in Norway in the 1990s, while the concentration of taxes remained largely unaltered. This means that tax progressivity has decreased in the period, as measured by summary indices of tax progressivity. In this paper I analyze individual income data to ascertain whether tax changes in the period can explain the observed decrease in tax progressivity. As marginal tax rates at high income levels have been substantially reduced in the period, for instance through the tax reform of 1992, it is expected that tax changes may have influenced the degree of inequality in pre-tax incomes. This behavioral effect is examined by deriving estimates of the elasticity of gross income with respect to the net-of-tax rate, obtained from various panel data regressions. The tax changes may also have shifted the distributional burden of taxes for unaltered level of pre-tax income inequality. In order to identify this (direct) effect of tax-law alterations, the same fixed distribution of pre-tax income is exposed to various tax-laws in the period.     

Distributional Implications of Tax Relief on Voluntary Private Pensions in Spain*

Using taxation statistics, this paper explores the distributional implications of tax relief on private pensions in Spain in 2002. For this purpose, the author suggests a decomposition of the Kakwani index and its generalisations that allows us to distinguish between the regressivity caused by targeting and that due to benefits allocation among recipients. This paper finds that these tax incentives are regressive ‐ mainly for the latter reason ‐ and have negative although small distributional effects. Finally, this work presents several proposals for reform of the current system and simulates their implications for equity.     

The Distributional Implications of Income Under‐Reporting in Hungary*

The ability and inclination of specific social groups to evade tax vary widely, and this leads to considerable variation in the actual tax burden on individuals with similar levels of income. Thus, ignoring tax evasion can be seriously misleading in terms of the distributive and fiscal effects of the tax system. This paper estimates the distributional implications of income tax evasion in Hungary, based on a random sample of the administrative tax records of nearly 230,000 individuals. Gross incomes declared in the administrative tax returns are compared with incomes stated in a nationally representative household budget survey. Our estimates show that the average rate of underreporting is 9–13 per cent, though this conceals a big difference between the self‐employed (who hide the greater part of their income) and employees. The estimates are likely to be lower bounds. These rates are used in a tax– benefit microsimulation model to calculate the fiscal and distributional implications of under‐reporting. Tax evasion reduces households' personal income tax payments by about 16–20 per cent. While the poverty rate increases only slightly, income inequality rises significantly, suggesting that high‐income households tend to evade tax proportionately more. Finally, we find that tax evasion largely reduces the progressivity of the tax system.     

Is a flat tax reform feasible in a grown-up democracy of Western Europe? A simulation study for Germany

The success of the flat rate income tax in eastern Europe suggests that this concept could also be a model for countries of western Europe. The present paper uses a simulation model to analyze the effects of revenue neutral flat rate tax reforms on equity and efficiency for the case of Germany. We find that a flat rate tax with a low tax rate and a low basic allowance yields positive static welfare effects amounting to approximately 1.8% of income tax revenue but increases income inequality. The increase in income inequality can be avoided by combining a higher tax rate with a higher basic allowance. But in this case, the efficiency gains vanish. We conclude that due to their limited efficiency effects and their problematic distributional impact, flat tax reforms are unlikely to spill over to the grown-up democracies of western Europe.      

Tax reforms and the underground economy: a simulation-based analysis

This paper studies the effects of several tax reforms in an economy where taxes are partially evaded by means of undeclared work. To this purpose, we consider a two-sector dynamic general equilibrium model calibrated to Italy which explicitly accounts for underground production. We construct various tax reform scenarios, such as ex ante budget-neutral tax shifts from direct to indirect taxes, and tax cuts on labor and business financed by decreases of government spending. Our results indicate that neglecting the existence of the underground sector may lead to severely miscalculating the macroeconomic effects of tax reforms. Further, the dimension of the underground sector is permanently and considerably reduced by changes in the tax mix that diminish the labor tax wedge. Reductions of the business tax prove to be highly expansionary in the presence of a sizable informal sector.     

Abolishing the Tax‐Free Threshold in Australia: Simulating Alternative Reforms*

This paper examines the role of the tax‐free income tax threshold in a complex tax and transfer system consisting of a range of taxes and benefits, each with its own taper rates and thresholds. Considering a tax and benefit system with benefit taper rates whereby some benefits are received by income groups other than those at the bottom of the distribution, it is suggested that a tax‐free threshold is not a necessary requirement to achieve redistribution. Four alternative policy changes, each involving the elimination of the tax‐free threshold in Australia and designed to achieve approximate revenue neutrality, were examined using the Melbourne Institute Tax and Transfer Simulator. A range of implications were examined, including labour supply responses to tax changes and the effects of policy changes on inequality and social welfare. The results demonstrate that it is possible to eliminate the tax‐free threshold under approximate overall revenue and distribution neutrality, but that it is impossible to improve labour supply incentives at the same time. In order to achieve improved incentives, either revenue or distribution neutrality has to be sacrificed.     

The impact of disclosure reform on the NZX's financial information environment

This study investigates the impact of changes to the New Zealand Exchange's listing rules and legislative amendments to the Securities Markets Act 1988 enacted in December 2002. The reforms provided statutory backing for a more stringent disclosure regime. We find evidence that non-dual listed firms, not subject to any prior enhanced disclosure regime, released more earnings-related information to the market in the post-reform period and announced their half-year and fiscal year-end results in a more timely manner. Our results also show that analysts' earnings forecast errors did not decline but analysts' forecasts showed less dispersion in the post-reform period. In respect of informational efficiency, we find evidence of a smaller abnormal return around the half-year and fiscal year earnings announcement date in the post-reform period. Our results suggest that the reforms improved the flow of information to investors, consistent with their intent.
