We introduce a new dataset that includes quantitative harmonized indices of tax reforms based on qualitative information of about 900 Economic Surveys from the OECD and 37,000 tax-related news from the IBFD archives. The data set provides indicators on tax reforms for tax rates and tax bases,...

We examine how trade openness influences income inequality within countries. The sample includes 139 countries over the period 1970-2014. We employ predicted openness as instrument to deal with the endogeneity of trade openness. The effect of trade openness on income inequality differs across...

We analyze how the combined effect of automatic stabilizers and discretionary changes in tax-benefit systems have affected the cushioning of income shocks in the Euro zone and the EU-27 in the period 2007–2014. We propose a new summary measure of the combined effect of automatic stabilizers...

This paper studies corporate taxation in a model where foreign investment of firms may affect the profitability of the investor firm's domestic activities. In this framework, corporate taxes distort the quality, not just the quantity of foreign direct investment flows. High-tax countries may see...

This paper examines the effects of real estate transfer taxes (RETT) on property prices using a rich micro dataset of roughly 17 million German properties for the period from 2005 to 2019. We exploit a 2006 constitutional reform that allows states to set their own RETT rates, leading to frequent...

This paper is the first to use information from individual country-by-country (CbC) re-ports to assess the extent of profit shifting by multinational enterprises. Unlike other data often used to evaluate the extent of profit shifting and tax avoidance, CbC reports pro-vide a complete coverage of...

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...

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...

The standard tax theory result that investment should not be distorted is based on the assumption that profits are locally bound. In this paper we analyze the optimal tax policy when firms are internationally mobile. We show that the optimal policy response to increasing firm mobility may be...

In this paper, we analyze tax competition in a model where investor firms have the choice between two types of investment, greenfield investment and mergers and acquisitions. We show that the coexistence of these two types of investment intensifies tax competition in comparison to the case where...
