Publications
Public Goods and Diversity in Democracies and Non-democracies
Co-authored with Christian Sander and Andrea Schneider
Published in Kyklos 77(3), 2024, 496-519
This paper analyzes how ethnic diversity affects the provision of public goods in democratic and non-democratic societies when political parties compete for voter support by offering a mix of private and public goods.
Work in Progress
Knowledge without Borders: The Global Effects of R&D Tax Incentives
Co-authored with Nadine Riedel and Johannes Voget
Revise and Resubmit at the Journal of International Economics
In this paper, we use rich firm-level data to empirically document that a significant part of the knowledge externalities induced by R&D tax subsidies accrue outside of the policy-setting country.
Corporate Taxes and Export Competition
Co-authored with Tobias Böhm, Antonia Hohmann and Nadine Riedel
Revise and Resubmit at the American Economic Journal: Economic Policy
In this paper, we use administrative customs and tax return data from South Africa to demonstrate that corporate taxes influence firms’ export performance and their competitiveness in international product markets.
Taxing Top Incomes in the Emerging World - Fiscal and Economic Impact under the Microscope
Co-authored with Christopher Axelson, Antonia Hohmann, Jukka Pirttilä and Nadine Riedel
Conditional Accept at the American Economic Journal: Economic Policy
In this paper, we study taxpayer responses to an increase in the top marginal tax rate in South Africa, drawing on exceptionally rich tax administrative data and a transparent empirical identification design. We establish that treated taxpayers strongly reduce their reported taxable income in response to the tax reform.
