  abstract     = {{This study examines the effect of tax complexity on the market value of publicly traded firms. Using firm-level measures of tax complexity, we find that a one standard deviation increase in tax complexity—comparable in magnitude to the rise following the U.S. Tax Cuts and Jobs Act—is associated with a 2.6% decline in Tobin’s Q. The effect is particularly pronounced for complexity arising from anti-avoidance regulations and post-filing procedures. The negative valuation effect is more substantial for firms with limited opportunities for international profit shifting, weak governance, or low internal information quality. Further analyses reveal that tax system complexity is associated with a reduced growth potential of firms and less R&D and thus negative real responses that go beyond negative investment effects. Overall, our findings provide novel evidence of the economic costs of tax complexity and contribute to the debate on the design of efficient and equitable tax systems.}},

  abstract     = {{We investigate how tax authorities use joint tax audits as a coordinated enforcement tool in cross-border transactions of a multinational firm. Joint tax audits aim to resolve potential tax disputes early, before such disputes escalate into costly and time-consuming resolution procedures that may not fully eliminate double taxation. Employing a game-theoretic model, we identify settings in which we expect joint audits to occur and investigate their effect on the firm's expected tax payments and tax audit efficiency. We find that the occurrence of joint audits critically depends on the double taxation risk in the absence of joint audits. Unless tax rules are consistently applied, joint audits can occur more often when this risk is higher. The reason is that the firm changes its income-shifting strategy to reduce its expected tax payments, and thereby also enables tax authorities to better target tax disputes via joint audits that would otherwise escalate. However, we identify conditions under which joint audits are then detrimental to tax audit efficiency, particularly when the firm prefers them most. Our results imply that cost-sharing arrangements for joint audits should be tailored to the level of double taxation risk, with firm involvement having the potential to improve efficiency when this risk is high.}},

  abstract     = {{This study introduces sloppiness---the inaccurate preparation of supporting information during tax disputes---as a neglected but critical factor influencing taxpayer noncompliance. We conceptualize sloppiness as arising both from imperfections in the internal information environment, exacerbated by structural uncertainty over litigation outcomes (factual dimension), and from strategic aversion to compliance effort (strategic dimension). We examine whether and to what extent improved documentation and engaging an internal monitoring expert can mitigate sloppiness and prevent litigation. Using a game-theoretic model, we derive equilibrium strategies for a tax manager's compliance effort, a monitoring expert's dispute resolution effort, and a tax authority's litigation decision. Absent a monitoring expert, we find that improved documentation consistently reduces the litigation probability. However, when a monitoring expert is present, we surprisingly find that improved documentation crowds out compliance effort and can increase the litigation probability. Overall, our results suggest that sloppiness can be overcome either through strong documentation alone or by engaging a monitoring expert when documentation is weak, with the latter approach becoming more attractive as the dispute resolution costs decline.}},

Dieser Beitrag untersucht diese unterschiedlichen Verwendungen aus einer kognitiv-grammatischen Perspektive anhand eines Korpus aus aktuellen Lebensmittelmarkennamen. Ziel ist es, die Arten der Komposition zu systematisieren. Als Ausgangspunkt dienen die in der linguistischen Forschung bisher üblichen Klassifizierungen von 'bio-' als initiales Konfix sowie 'bio' als Kürzung. Die Analyse zeigt, dass die Komponente '(-)bio(-)' überwiegend als gebundene oder ungebundene spezifizierende Erst- oder auch Zweiteinheit in regulären Konfix-Komposita und kompositumähnlichen Bildungen, die als Markennamen eingesetzt werden, gebraucht wird. Seltener fungiert die Komponente selbst als Profildeterminante. Die Komponente '(-)bio(-)' wird demzufolge zur Bildung von Markennamen variabler gebraucht, als durch die Einordnung von bio- als vornehmlich linke, gebundene Einheit in Komposita bislang angenommen wurde.}},

We clarify the theoretical basis for the waveguides with potentially non-diagonal core permittivity. Symmetry classes can be distinguished that differ in their consequences for potential modal degeneracy and polarization conversion. Our rigorous numerical analysis by means of a finite-element solver takes the anisotropy of the lithium niobate cores rigorously into account. We discuss extensive data for effective indices, polarization properties, and hybridization of guided modes, in single- and multimode channels. Scans over the waveguide width and orientation as primary parameters are complemented by a series of illustrations of vectorial mode profiles. These turn out to be essentially complex in cases of X-cut channels at non-crystal-axis-aligned orientations.}},

To assess how teachers in the different implementation groups made use of the TPD in their lesson planning, participants submitted hypothetical lesson sequences on early numeracy, which were analysed for instructional quality, covered content, and the visible implementation of the provided educative curriculum materials using qualitative content analysis. The results indicated that both TPD implementations positively affected VS teachers’ knowledge related to EME but not their beliefs. While the instructional quality of the lesson sequences varied across both groups, participants who received the TPD course appeared to use the educative curriculum materials more often and to cover more content.</jats:p>}},

Traditional fuzzing evaluations typically focus on overall fuzzer performance across a set of target programs, yet few benchmarks consider how fine-grained program features influence fuzzing effectiveness. To bridge this gap, we introduce FeatureBench, a novel benchmark designed to generate programs with configurable, fine-grained program features to enhance fuzzing evaluations. We reviewed 25 recent grey-box fuzzing studies, extracting 7 program features related to control-flow and data-flow that can impact fuzzer performance. Using these features, we generated a benchmark consisting of 153 programs controlled by 10 fine-grained configurable parameters. We evaluated 11 fuzzers using this benchmark, with each fuzzer representing either distinct claimed improvements or serving as a widely used baseline in fuzzing evaluations. The results indicate that fuzzer performance varies significantly based on the program features and their strengths, highlighting the importance of incorporating program characteristics into fuzzing evaluations.</jats:p>}},
