The Distribution of National Income in Germany, 1992-2019
Stefan Bach, Charlotte Bartels, Theresa Neef
IWH Discussion Papers,
No. 25,
2024
Abstract
This paper analyzes the distribution and composition of pre-tax national income in Germany since 1992, combining personal income tax returns, household survey data, and national accounts. Inequality rose from the 1990s to the late 2000s due to falling labor incomes among the bottom 50% and rising incomes in the top 10%. This trend reversed after 2007 as labor incomes across the bottom 90% increased. The top 1% income share, dominated by business income, remained relatively stable between 1992 and 2019. A large share of Germany’s top 1% earners are non-corporate business owners in labor-intensive professions. At least half of the business owners in P99-99.9 and a quarter in the top 0.1% operate firms in professional services – a pattern mirroring the United States. From 1992 to 2019, Germany’s top 0.1% income concentration exceeded France’s and matched U.S. levels until the late 2000s.

R&D Tax Credits and the Acquisition of Startups
William McShane, Merih Sevilir
IWH Discussion Papers,
No. 15,
2023
Abstract
We propose a novel mechanism through which established firms contribute to the startup ecosystem: the allocation of R&D tax credits to startups via the M&A channel. We show that when established firms become eligible for R&D tax credits, they increase their R&D and M&A activity. In particular, they acquire more venture capital (VC)-backed startups, but not non-VC-backed firms. Moreover, the impact of R&D tax credits on firms’ R&D is increasing with their acquisition of VC-backed startups. The results suggest that established firms respond to R&D tax credits by acquiring startups rather than solely focusing on increasing their R&D intensity in-house. We also highlight evidence that startups do not appear to benefit from R&D tax credits directly, perhaps because they typically lack the taxable income necessary to directly benefit from the tax credits. In this context, established firms can play an intermediary role by acquiring startups and reallocating R&D tax credits, effectively relaxing the financial constraints faced by startups.

How Effective are Bank Levies in Reducing Leverage Given the Debt Bias of Corporate Income Taxation?
Franziska Bremus, Kirsten Schmidt, Lena Tonzer
SUERF Policy Brief,
No. 21,
2020
Abstract
To finance resolution funds, the regulatory toolkit has been expanded in many countries by bank levies. In addition, these levies are often designed to reduce incentives for banks to rely excessively on wholesale funding resulting in high leverage ratios. At the same time, corporate income taxation biases banks’ capital structure towards debt financing in light of the deductibility of interest on debt. A recent paper published in the Journal of Banking and Finance shows that the implementation of bank levies can significantly reduce leverage ratios, however, only in case corporate income taxes are not too high. The result demonstrates that the effectiveness of regulatory tools can depend upon non-regulatory measures such as corporate taxes, which differ at the country level.
