The management of football clubs has increasingly become a complex endeavour due to their evolution into multifaceted enterprises and the rising complexity of stakeholder relationships. Clubs vary in their ability to navigate this complexity, making management quality a decisive factor in gaining a competitive edge. The 2024 edition of the FoMa Q-Score ranking builds on the framework developed by ZÜLCH & PALME (2017), evaluating management quality across four key dimensions: Sporting Success, Financial Performance, Fan Welfare Maximization, and Leadership & Governance. These dimensions, as confirmed by leading football executives (CRUZ, SCHREGEL & ZÜLCH, 2022), provide an objective assessment of the critical success factors for professional football clubs.
The increased competition at the top of the Bundesliga in the 2023/2024 season has reinforced the business model of German football, underscoring that sporting success alone is not enough to come out as a top-tier club in this encompassing ranking. Achieving long-term competitiveness and stability requires a solid financial foundation, effective fan engagement, and strong leadership from club executives. As the league progresses beyond the pandemic era, these trends reflect a lasting and sustainable shift. With forthcoming changes in European competition formats and the associated increases in revenues, clubs are strategically position-ing themselves for enduring success. The FoMa Q-Score, acknowledged in both academic and practical spheres, continues to offer valuable insights. This tool enables clubs to benchmark their strategies against peer group clubs and beyond, ensuring they maintain or enhance their competitive standing.

Our study provides insights into the growing thematic niche of social media influencers, with a special focus on the emergence of financial influencers (finfluencers) who share information on personal financial decision-making. Our exploratory research examines finfluencers’ segmentation, motivations, and business models, offering insights to various stakeholders. Using a novel identification strategy to select 373 German-speaking finfluencers on Instagram, we analysed 106 valid survey responses. Our findings reveal that finfluencers regard themselves as advocates of financial education, despite apparent contradictions in their business models. Furthermore, finfluencers not only serve as a novel marketing channel for financial institutions but may also play a role in future financial communication strategies aimed at retail investor relations. Ultimately, our study not only lays the groundwork for future research but also recommends using finfluencers as social agents for enhancing individuals’ level of financial literacy, which is a critical skill set for overall societal well-being.

Founding a company
(2011)
The article on legal forms in Switzerland provides an overview on important legal aspects corporations and entrepreneurs need to understand to make informed decisions about which legal form to embark on. It starts with an introduction into the general laws and regulations with regard to setting up and running a business and provides an overview on possible legal forms. It uses a structured analysis framework to analyze seven relevant legal forms: the sole proprietorship (Einzelfirma), the ordinary partnership (Einfache Gesellschaft), the General partnership (Kollektivgesellschaft), the partnership limited by shares (Kommanditgesellschaft), the silent partnership (Stille Gesellschaft), the corporation (Aktiengesellschaft) and the limited liability company (GmbH). The article ends with a discussions and evaluation of the advantages and disadvantages of the different legal forms and provides exemplary recommendations depending on the individual case of the founders.

Sustainable competitiveness
(2017)
This paper argues for a productivity-based view on competitiveness considering sustainability aspects. A novel composite index of sustainable competitiveness for 272 European NUTS-2 regions in 28 countries is established. Principal component factor analysis and a structural equation model are utilized to identify the drivers of sustainable competitiveness, to explore the relationships between the different components, and to determine the indicator weighting and aggregation. Thereby, five mutual interdependent drivers are identified: social and ecological fundamentals, micro and macroeconomic competitiveness, and intermediate outputs. The index reveals important insight for policy makers into the sustainable competitiveness trajectory of European regions.

Given the still ambiguous empirical evidence, this paper analyzes the eironmental regulation-productivity nexus using an extended Neo-Schumpeterian productivity model. Thereby, the paper adds to the literature in three ways: First, shadow prices of energy along with industrial energy prices are employed as relative measures of eironmental policy stringency. To ensure the robustness of the results, the model is also estimated for five alternative regulatory measures that have been applied in prior research. Second, the study addresses the potential endogeneity of the eironmental regulation, innovation, and trade openness measures as a source of the inconclusive results. Third, as one of few analyses on the Porter Hypothesis, the paper utilizes a cross-country multi-sectoral dataset including also newly industrialized countries and former transition economies. The estimates show that the positive effects of increases in eironmental policy stringency on productivity, which are often found in the more recent studies, change to insignificant and partly negative effects once endogeneity is fully controlled for. Hence, no support for the strong Porter Hypothesis can be found. Instead, more stringent eironmental regulation fosters innovation and, therefore, has an indirect, yet not dominant, positive effect on productivity growth.

The principle of differential monotonicity for cooperative games states that the differential of two players' payoffs weakly increases whenever the differential of these players' marginal contributions to coalitions containing neither of them weakly increases. Together with the standard efficiency property and a relaxation of the null player property, differential monotonicity characterizes the egalitarian Shapley values, i.e., the coex mixtures of the Shapley value and the equal division value for games with more than two players. For games that contain more than three players, we show that, cum grano salis, this characterization can be improved by using a substantially weaker property than differential monotonicity. Weak differential monotonicity refers to two players in situations where one player's change of marginal contributions to coalitions containing neither of them is weakly greater than the other player's change of these marginal contributions. If, in such situations, the latter player's payoff weakly/strictly increases, then the former player's payoff also weakly/strictly increases.

We suggest a weak version of differential monotonicity for redistribution rules: whenever the differential of two persons’ income weakly increases, then their post-redistribution rewards essentially change in the same direction. Together with efficiency, non-negativity, and the null society property, weak differential monotonicity essentially characterizes redistribution via taxation at a
fixed rate and equal distribution of the total tax revenue, i.e., a flat tax and a basic income.

The main objective of international financial reporting under both US GAAP and IFRS is to provide information that is useful to iestors. However, it is questionable whether this goal can be fully realized without proper and strict enforcement, which ensures faithful and consistent application of the relevant accounting standards. Within the multiplicity of studies iestigating enforcement mechanisms and reactions to enforcement consequences, this paper provides an overview on the current state of research on enforcement as a corporate governance mechanism. We analyze prior enforcement literature from both internal and external corporate governance perspectives in order to show effects of enforcement on different mechanisms of financial reporting oversight. It becomes evident that most research does not address either efficiency or efficacy of enforcement mechanisms and that most causes and consequences of error announcements in the European setting have not been iestigated yet. Hence, we deduce further research opportunities focused on enforcement procedures and mechanisms in the European setting.

The significant heterogeneity among family firms has emerged as a commonly accepted paradigm in the research field. This systematic literature review establishes how the heterogeneity affects the board of directors, an institution that typically forms the most important pillar in the formal governance system of family businesses. As one of the first, the review provides an overview on the family-related factors that determine the board of directors’ tasks, composition, and processes. The systematic analysis, clustering, and synthesis of previous research yields six main determinants that are specific to the boards of family firms, namely generational stage, family culture, family power, family experience, CEO family stakes, and director kinship ties. From a methodological perspective, a heavy reliance on survey-based quantitative research can be observed in existing studies. For future research, I suggest a stronger focus on the dynamic evolution of the board over time, an integration of alternative theories in addition to agency theory, as well as the use of qualitative research strategies, such as case study research, to better understand the internal processes and evolution of family firm boards.

The principle of differential marginality for cooperative games states that the differential of two players‘ payoffs does not change when the differential of these players‘ productivities does not change. Together with two standard properties, efficiency and the null player property, differential marginality characterizes the Shapley value. For games that contain more than two players, we show that this characterization can be improved by using a substantially weaker property than differential marginality. Weak differential marginality requires two players‘ payoffs to change in the same direction when these players‘ productivities change by the same amount.
