This paper investigates the relationship between economic growth in Poland and selected elements of fiscal policy and private spending on education. We use the Mankiw-Romer-Weil model, augmented with learning-by-doing and spillover-effects and with concepts from the literature on optimal fiscal...

The semi-dual income tax typically combines a progressive tax schedule for labour and pension income with low and often flat and differentiated nominal tax rates on some forms of capital income. This paper discusses the rationale for the adoption of semi-dual income tax in the taxation of...

The purpose of this paper is to survey the theoretical literature on wealth transfer taxation. The focus is normative: we are looking at the design of an optimal tax structure from the standpoint of both equity and efficiency. The gist of this survey is that the optimal design crucially depends...

In this paper we show that in a two sector economy with heterogeneous agents and competitive markets, in a steady state the optimal capital income tax rate is in general different from zero. The optimal tax policy in this setting depends on the relative price difference. In a two sector economy...

Mirrlees' optimal income tax formula has never been proven rigorously, and it is hard to understand it in economic terms. We prove an analogous formula for an economy with finitely many persons. This is easy and allows a simple economic interpretation. Thereafter, Mirrlees' original formula is...

Pension benefit rules depend on individual history far more than taxes do, and age plays a much larger role in pension determination than in tax determination. Apart from some simulation studies, theoretical studies of optimal tax design typically contain neither a mandatory pension system nor...

This paper presents the case for tax progressivity based on recent results in optimal tax theory. We consider the optimal progressivity of earnings taxation and whether capital income should be taxed. We critically discuss the academic research on these topics and when and how the results can be...

The Organisation for Economic Co-Operation and Development (OECD) recently proposed an interest barrier to fight tax base erosion and profit shifting (BEPS). We use the introduction of such an interest deductibility restriction in Germany as a quasi-experiment and find significant corporate...

The present publication is concerned with the process of thin capitalisation in the countries of OECD. Two methods for financing companies are discerned in relation to this phenomenon, i.e. debt and equity financing. The tax-related consequences of the method of equity financing of companies are...

The following paper explores the issue of thin capitalisation in Organisation for Economic Co-operation and Development (OECD) member countries. There are two methods used by financing companies that are strongly related to this phenomenon: debt and equity financing. The tax-related consequences...
