In her book, Flat Earth: The history of an infamous idea, 1 Christine Garwood explains that from medieval times, long predating Christopher Columbus’ famous voyages, educated people knew that the earth was not flat. Nevertheless, the flat earth myth persisted for centuries and even has some,...

Based on the agreed Pillar 1 threshold of profitability of 10% (and given that financial and extractive companies are excluded), then only 78 of the world’s 500 largest companies will be affected. If the proportion of profit above this threshold liable to Amount A is set to 20% (from the...

In November 2020, Illinois voters will consider an amendment that would strike the following two sentences from the Illinois constitution. “A tax on or measured by income shall be at a non-graduated rate. At any one time there may be no more than one such tax imposed by the State for State...

In this paper, we define a new class of richness measures. In contrast to the often used headcount, these new measures are sensitive to changes in rich persons' income and therefore allow for a more sophisticated analysis of richness. We demonstrate the application of these new measures to...

The flat income tax has become increasingly popular recently, yet its implementation is limited to Eastern Europe. We analyse the distributional and efficiency effects of flat tax scenarios for Western European countries. Our simulations show that flat tax rates required to attain revenue...

Mircrosimulation models (MSM) and Computable General Equilibrium models (CGE) have both been widely used in policy analysis. The combination of these two model types allows the utilisation of the advantages of both types. The aim of this paper is to describe the state-of-the-art in simulation...

Russia dramatically reduced its higher rates of personal income tax (PIT) in 2001 establishing a single marginal rate at the low level of 13 percent. In the following year, real revenue from the PIT actually increased by about 26 percent. This 'flat tax' experience has attracted much attention...

The dual income tax combines a progressive tax schedule for labour income with a low flat tax rate on capital income and corporate income. This paper restates the case for the dual income tax and discusses alternative methods of taxing business income under such a tax system, paying special...

The success of the flat rate tax in Eastern Europe suggests that this concept could also be a model for the welfare states of Western Europe. The present paper uses a simulation model to analyse the effects of revenue neutral flat rate tax reforms on equity and efficiency for the case of...

We develop and estimate a model of jointly optimal income taxes for different types of income. Compared to standard optimal tax formulas, optimal schedular income tax rates additionally depend on cross-elasticities between tax bases capturing fiscal externalities. We discuss two applications:...

We study the determination of flat tax systems using a workhorse macroeconomic model of inequality. Our first result is that, despite the multidimensional policy space, equilibrium policies are typically unique (up to a fine grid numerical approximation). The majority voting outcome features (i)...

Much of the literature on flat tax reforms has highlighted the benefits of introducing flat personal income tax systems in transition economies. The advocated benefits of flat tax systems range from their simplicity, higher compliance and lower distortionary effects on growth and employment....

Based on the agreed Pillar 1 threshold of profitability of 10% (and given that financial and extractive companies are excluded), then only 78 of the world's 500 largest companies will be affected. If the proportion of profit above this threshold liable to Amount A is set to 20% (from the range...

Small changes to the parameters of a system can lead to abrupt qualitative changes of its behavior, a phenomenon known as bifurcation. Such instabilities are typically considered problematic, however, we show that their power can be leveraged to design novel types of mechanisms. Hysteresis...

We study three budget-neutral reforms of the German tax and transfer system designed to improve work incentives for people with low incomes: a feasible flat tax reform that provides a basic income which is equal to the current level of the means tested unemployment benefit, and two alternative...

This paper analyzes the quantitative benefits of switching from a flat tax regime to a progressive tax one, and viceversa. The tax model includes three scenarios of how the income of the tax payers are distributed and explain the different results. It also includes an extension of tax avoidance...

The objective of the paper is to examine whether the advantages and disadvantages mentioned in the literature of the flat rate income tax could be observed in Hungary. Personal income tax data provided by the Hungarian National Tax and Customs Administration was used to check the arguments. It...

Ein Flat-Tax-Modell mit einer breiten Bemessungsgrundlage und einem einheitlichen Steuersatz würde die Erbschaftssteuer vereinfachen. Im Vergleich zum jetzigen Recht müssten dann Erben von kleinen und mittleren Unternehmen höhere Steuern zahlen, während große Erb- und Schenkungsfälle in...

The aim of the article is to examine the impact of progressive personal income tax rates and the effectiveness of this tax as an automatic economic stabilizer. The assessment of automatic stabilizers is based on the estimates of tax cyclical components. The study shows that the output elasticity...

This paper explores the taxation of corporations in the wider context of capital income taxation. The pros and cons of various income-based and cash-flow forms of corporation tax (CT) are discussed. The paper concludes that the dual income tax (DIT), which taxes all capital income at the...

The research begins with a brief overview of the personal income taxation trends in developed and transition countries in the past thirty years. During this period there has been a shift in developed countries from equity towards efficiency principle, conducted by a reduction of top progressive...

This paper provides a microeconometric analysis of labour force participation elasticities in Slovakia where we study the elasticity with respect to a unique tax reform whereby the flat tax was backtracked and replaced by a progressive tax. By estimating a probability model for labour force...

The purpose of the paper is to study the effect of taxation on dividend payments and ex-dividend price-changes in Sweden during 1991-1995. Tax changes in Sweden during the 1990s were implemented in such a way that they provide an opportunity to include direct measures of the tax-treatment of...
