I employ an economic model in which a tax manager’s tax planning effort shapes corporate tax planning and a strategic tax auditor makes a technology-based audit decision. I show that strengthening tax enforcement always increases tax revenues, but decreases the number of audits only under narrow conditions, so that its effect on tax audit efficiency is often ambiguous. Improving tax audit technology has more nuanced implications. When the strength of tax enforcement is sufficiently high, gradual improvements in tax audit technology crowd out audit incentives and, surprisingly, reduce tax revenues, while sufficiently large improvements can overturn this adverse revenue effect. At the same time, improved technology lowers unnecessary audits once the strength of tax enforcement exceeds a minimum level. Therefore, sufficiently large technology improvements improve tax audit efficiency once this minimum level is exceeded. The results have important policy and empirical implications in an environment of constrained fiscal budgets and rapidly advancing audit technologies.}}, author = {{Dyck, Daniel}}, title = {{{Corporate Tax Planning and Technology-Based Enforcement}}}, doi = {{10.2139/ssrn.5186857}}, year = {{2025}}, } @article{63580, author = {{Dyck, Daniel and Hechtner, Frank and Maiterth, Ralf and Sureth-Sloane, Caren}}, journal = {{Steuer und Wirtschaft}}, number = {{Sonderheft NeSt}}, pages = {{26--44}}, title = {{{Abschreibungen als Mittel der Investitionsförderung in Deutschland - Möglichkeiten, Grenzen und Perspektiven evidenzbasierter Analysen}}}, volume = {{102}}, year = {{2025}}, } @techreport{65863, abstract = {{We investigate the impact of Brexit on the corporate bond market by analyzing a comprehensive database covering corporate bond listings on European and UK trading venues.

We provide empirical evidence that the mixed results are due to the difficulty of identifying reliable variables to measure concentration and market power. Design/methodology/approach Using data from 3,943 banks operating in the European Union (EU)-15 between 2013 and 2020, we employ linear regression models on panel data. Banking market concentration is measured by the Herfindahl–Hirschman Index (HHI), and market power is estimated by the product-specific Lerner Indices for the loan and deposit market, respectively. Findings Our analysis reveals a significantly stability-decreasing impact of market concentration (HHI) and a significantly stability-increasing effect of market power (Lerner Indices). In addition, we provide evidence for a weak (or even absent) empirical relationship between the (non)structural measures, challenging the validity of the structure-conduct-performance (SCP) paradigm. Our baseline findings remain robust, especially when controlling for a likely reverse causality. Originality/value Our results suggest that the HHI may reflect other factors beyond market power that influence banking stability. Thus, banking supervisors and competition authorities should investigate market concentration and market power simultaneously while considering their joint impact on banking stability.}}, author = {{Herwald, Sarah and Voigt, Simone and Uhde, André}}, journal = {{Journal of Risk Finance}}, keywords = {{market concentration, market power, banking stability, European banking}}, number = {{3}}, pages = {{510 -- 536}}, title = {{{The conditional impact of market consolidation and market power on banking stability – Evidence from Europe}}}, doi = {{https://doi.org/10.1108/JRF-03-2023-0075}}, volume = {{25}}, year = {{2024}}, } @inbook{56012, author = {{Schulz, Pascal}}, booktitle = {{Produktion, Logistik und Controlling im Zeitalter der Digitalisierung}}, editor = {{Betz, Stefan}}, isbn = {{978-3-339-13906-1}}, pages = {{49}}, publisher = {{Dr. Kovac}}, title = {{{Technische und ökonomische Implikationen des Einsatzes kunststoffbasierter additiver Fertigungsverfahren in der Produktion}}}, year = {{2024}}, } @inbook{55892, author = {{Betz, Stefan}}, booktitle = {{Produktion, Logistik und Controlling im Zeitalter der Digitalisierung}}, editor = {{Betz, Stefan}}, isbn = {{978-3-339-13906-1}}, pages = {{32}}, publisher = {{Dr. Kovac}}, title = {{{Entwicklung eins Tourenplanungsmodells zur Unterstützung der Wahl zwischen elektrisch und mit Diesel betriebenen LKW}}}, year = {{2024}}, } @inbook{56013, author = {{Christian, Koch}}, booktitle = {{Produktion, Logistik und Controlling im Zeitalter der Digitalisierung}}, editor = {{Betz, Stefan}}, isbn = {{978-3-339-13906-1}}, pages = {{41}}, publisher = {{Dr. Kovac}}, title = {{{Zielorientierte Steuerung durch ganzheitliches Unternehmenscontrolling in Krisensituationen - am Beispiel von Covid 19}}}, year = {{2024}}, } @inbook{56011, author = {{Plückebaum, Daniel}}, booktitle = {{Produktion, Logistik und Controlling im Zeitalter der Digitalisierung}}, editor = {{Betz, Stefan}}, isbn = {{978-3-339-13906-1}}, pages = {{38}}, publisher = {{Dr. Kovac}}, title = {{{Bestimmung des zieloptimalen Automatisierungsgrads ausgewählter Montagevorgänge}}}, year = {{2024}}, } @inbook{56008, author = {{Puls, Christoph}}, booktitle = {{Produktion, Logistik und Controlling im Zeitalter der Digitalisierung}}, editor = {{Betz, Stefan}}, isbn = {{978-3-339-13906-1}}, pages = {{28}}, publisher = {{Dr. Kovac}}, title = {{{Industrial Internet of Things - Enabler der digitalen Transformation zur Smart Factory}}}, year = {{2024}}, } @inbook{56009, author = {{Koch, Christian}}, booktitle = {{Produktion, Logistik und Controlling im Zeitalter der Digitalisierung}}, editor = {{Betz, Stefan}}, isbn = {{978-3-339-13906-1}}, pages = {{34}}, publisher = {{Dr. Kovac}}, title = {{{Wandel im Controlling - Digitalisierung und ihre Auswirkungen auf den Personalbedarf}}}, year = {{2024}}, } @inbook{56010, author = {{Faupel, Christian}}, booktitle = {{Produktion, Logistik und Controlling im Zeitalter der Digitalisierung}}, editor = {{Betz, Stefan}}, isbn = {{978-3-339-13906-1}}, pages = {{32}}, publisher = {{Dr. Kovac}}, title = {{{Digitale Instrumente des Cost Engineering}}}, year = {{2024}}, } @book{55890, editor = {{Betz, Stefan}}, isbn = {{978-3-339-13906-1}}, pages = {{436}}, publisher = {{Dr. Kovac}}, title = {{{Produktion, Logistik und Controlling im Zeitalter der Digitalisierung}}}, year = {{2024}}, } @article{56653, author = {{Birnbaum, Kirsten and Heckemeyer, Jost H. and Linau, Annette and Sureth-Sloane, Caren}}, journal = {{Schmalenbach IMPULSE}}, pages = {{1--17}}, title = {{{Steuerwettbewerb als Chance}}}, doi = {{https://doi.org/10.54585/OAHI2295}}, volume = {{3}}, year = {{2024}}, } @techreport{56814, abstract = {{This study investigates whether, how, and under what conditions the expected positive association between cooperative compliance programs and tax compliance is attenuated by tax complexity. Many countries have implemented cooperative compliance programs to improve compliance, however, the effectiveness of these programs varies across countries. I expect and find that the complexity of a country's tax system might impair the compliance-enhancing impact of cooperative compliance programs. Using cross-country data of 57 countries, I find that cooperative compliance programs generally promote compliance, except in countries with highly complex tax codes. Moreover, these programs are positively associated with tax compliance even if tax procedures, such as tax filing and payment or tax audits, are highly complex. My findings suggest that cooperative compliance programs can compensate for mistrust caused by complex tax procedures and enhance compliance. However, they may not be effective tools to enhance compliance in complex tax codes. }}, author = {{Schipp, Adrian}}, title = {{{Too Complex to Cooperate?
