The paper motivates and describes the tax treatment of German retirement benefits and pensions after the 2005 reform initiated by the German Federal Constitutional Court. The main question is whether this reform has produced a "level playing field" among the many instruments generating...

On 3 June 2020, the German government announced a temporary value added tax (VAT) rate reduction. VAT rates were reduced on 1 July 2020 and went back to their previous level on 1 January 2021. We study the price effects of the temporary VAT rate reduction using a web-scraped data set covering...

In West Africa, the Value Added Tax (VAT) policy consists of a uniform tax rate, but several items consumed by rich and poor households, are exempted. We provide an optimal tax framework to reflect on the welfare effects of such a tariff structure, in the context of current debates on domestic...

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...

This article discusses the effects of taxation on the discrete choice of alternative projects. In particular, it is shown that if taxation affects the optimal timing of irreversible investment, then the discrete choice is distorted as well. This result has both methodological and political...

This paper provides a conceptual review of how the impact of taxes on the incentive to invest in the corporate sector can be measured. The focus is on measures derived from economic theory. Two measures are derived effective marginal and average tax rates which reflect different forms of...

This paper discusses techniques for measuring the incidence of carbon taxes across different household income groups and provides some cross-country estimates of these effects for selected advanced countries. The general message of this paper is that distributional concerns should not...

This study provides a survey on corporate taxes around the world. Our analysis has three main objectives. First, we collect tax data and calculate (forward-looking) effective tax measures for a large sample of countries and recent years. We particularly describe how these measures vary over time...

Forward looking measures like the well-known effective marginal tax rate developed by King and Fullerton (1984) are often criticized for not taking into account the complexity of the tax law. This paper derives a method of evaluating this kind of measure and of quantifying the bias resulting...

Tax neutrality towards alternative financing instruments for corporate investment is a ubiquitous demand in the political debate. At the same time, the literature is surprisingly silent about the magnitude of possible efficiency costs of a departure from tax neutrality. Against this background,...
