    The Idleness of Mobility Behaviour – Contributions and Challenges of Subsidisation and Digitalisation to Turn the Tide in Favor of Sustainable Public Transport
    (2026-03-24)
    Hahn, Andreasorcid-logo
    This dissertation examines how innovative mobility concepts, price mechanisms, and technological developments influence mobility behaviour, the acceptance of sustainable modes of transport, and the future design of public transport (PT) in Germany. Drawing on Vincent Kaufmann’s concept of mobility as a form of social action potential, mobility is understood as the interplay of structural access, individual capabilities, and cultural processes of appropriation. The dissertation thus addresses a research gap at the intersection of behavioural economics, social sciences, and technological mobility research. The work employs a mixed-method design combining quantitative analyses on price and subsidy mechanisms (Studies 1–3) with qualitative investigations on digitalisation and autonomous buses (Studies 4–6). User surveys, regression models, expert interviews, and scenario-based explorations provide a differentiated empirical picture of current and potential mobility dynamics. The findings reveal that price incentives – such as climate tickets or rising fuel prices – can trigger short-term shifts in the modal split, yet do not induce a sustained shift away from private motorised transport (PMT) in the absence of structural improvements. Once subsidies run out, PMT is frequently chosen again, particularly in regions with limited PT quality. Price mechanisms thus unfold their effectiveness only in combination with reliable, spatially accessible, and userfriendly services – a core dimension of Kaufmann’s mobility concept. Furthermore, the results show that ecological motivation is constrained by economic conditions. During periods of economic volatility, financial considerations tend to dominate mobility decisions. Socially balanced fare models and targeted subsidies are therefore central prerequisites for socially viable mobility strategies. Digitalisation offers the potential to structurally reduce deficits in PT provision. Digital bus stop concepts, real-time information and mobility platforms improve accessibility and the user experience, while on-demand services enhance flexibility, particularly in rural areas. However, the success of digital innovations ultimately depends on societal acceptance. The studies indicate that, although autonomous buses are regarded as a response to the growing shortage of bus drivers, reservations persist, especially among younger users, driven less by technical concerns and more by social and work-related considerations. The findings show implications for three groups of stakeholders. For policy makers, a systemic approach is required that integrates pricing, infrastructure development, and digitalisation. For mobility users, the results highlight that conscious mode choice, digital competencies, and active participation in feedback or planning processes constitute essential elements of stable modal-shift dynamics. Transport companies face the challenge of evolving from reactive service providers to strategic designers of multimodal mobility environments that integrate physical, digital, and fare-related components. Overall, the studies demonstrate that sustainable modal shift is not the result of isolated measures but emerges from the multifaceted interaction of structural, cultural, and technological factors. Transforming PT therefore requires long-term, socially balanced, and technologically adaptive strategies. Looking ahead, digital innovations, autonomous driving, and integrative subsidy structures will be key components of a mobility culture that aligns ecological objectives with social participation and everyday functionality. This dissertation thus contributes to the theoretical foundation and empirical analysis of the mobility transition and identifies central avenues for future national and international research.

    Consumers’ Information Systems: Managing Consumption within Households and in Interaction with Digital Firms
    (2026-05)
    Dethier, Erikorcid-logo
    This dissertation investigates the information systems underlying consumption by shifting the analytical focus from firms to private households. While traditional Information Systems research has extensively examined how digital technologies support organizational processes within firms, the complementary domain of consumption—where individuals coordinate, manage, and enact market transactions—has remained comparatively underexplored. Building on the premise that consumption is not a passive act but involves substantial managerial, coordinative, and cognitive effort, I conceptualize these activities as consumers’ work. This work unfolds within the household as an economic unit as well as at its boundary to the market, where consumers interact with firms under conditions of bounded rationality, information asymmetries, and an increasing digitalization driven by the platform economy and a growing “everything-as-a-service” subscription paradigm. The theoretical foundation integrates perspectives from sociology, (New) Home Economics, as well as New Institutional approaches, and synthesizes them to be examined through a socio-technical IS lens. Sociological research highlights the often invisible, unequally distributed, and cognitively demanding nature of household labor, particularly its managerial and administrative dimensions. Economic perspectives reconceptualize households as productive units and emphasize the costs of coordination inherent in market transactions. Complementing these views and following prior empirical research on money work within the CSCW and HCI communities as well as theoretical considerations on technically intermediated markets, IS research provides a newly socio-technical understanding of consumers’ work systems and mechanisms. Methodologically, the dissertation follows a retroductive design inquiry grounded in critical realism and abductive reasoning, moving iteratively between a problem space (consumers’ work) and a solution space (emerging work-supporting technologies). It combines inductive empirical exploration with theory-building across four interrelated studies conducted in Germany, each addressing a specific research objective. Study 1 follows the artifact “invoice” through 17 households to reconstruct domestic accounting as a spatio-temporal practice. Study 2 develops a taxonomy of twelve administrative task categories and quantifies temporal workload, mental workload, and satisfaction in an online survey with 617 socio-demographically distributed participants. Study 3, drawing on the same dataset, maps the devices, tools, specialized software, and physical workplaces consumers appropriate for this office-like work at home. Study 4 employs interviews and a week-long field study with five intermediary firms in finance, insurance, utilities, health, and general administration to investigate how intermediaries mediate and partially take over consumers’ work in market coordination. Together, the studies provide a mixed-method, multi-level, and multi-perspective understanding of consumers’ work across different tasks involving different kinds of technologies. The dissertation’s outcome advances both theory and practice by conceptualizing consumers’ work as a boundary practice situated between households and markets, articulated through a socio-technical framework that captures the interplay of structures, people, tasks, and technologies. Empirically, the findings demonstrate that consumers perform substantial, often underestimated and unseen labor in managing consumption. Invoice handling, for example, unfolds as a fragmented spatio-temporal practice across paper-based and digital media. The identified twelve administrative task categories differ considerably in mental workload and satisfaction, with tax affairs, problem management, governmental affairs, long term contracts, and insurance emerging as priority pain points for design. Emerging digital services, from financial management tools and contract managers to intermediary platforms, already intervene in and reshape these work practices. Conceptually, the dissertation contributes (I.) an integrated chain of consumption management that links intra-household administration with market-directed activities across five phases (anticipating, identifying, deciding, monitoring, and modifying); (II.) the introduction of heteronomy imposed by external institutions as a design variable that work supporting technology must explicitly address rather than ignore; and (III.) a reframing of intermediaries as a socio-technical infrastructure of market cooperation that bridges social and technical interoperability gaps through its own socio-technical measures, such as “adversarial” or “backward” interoperability. In doing so, the dissertation provides an empirically grounded conceptualization of theories such as intermediation or Vendor Relationship Management while also generating new empirical evidence and concepts. By positioning consumers as active agents who perform essential economic work, this dissertation opens a new line of inquiry for IS research and contributes to a broader understanding of digital transformation that encompasses not only firms but also the everyday practices of individuals in the economy. It thereby extends the traditionally firm-centered focus of Business Informatics with a complementary consumer-centered perspective and positions Consumer Informatics as an essential site of inquiry within IS research.

    Wenn der Markt nicht regeln kann: Klimaneutralität zwischen Wirtschaftswachstum und gesellschaftlicher Akzeptanz
    (2026-06-23)
    Dahlmann, Sarahorcid-logo
    Die Aktualität des Miteinanders von Wirtschafts- und Klimapolitik ist kaum zu übersehen. In vier Kapiteln beschäftigt sich die kumulative Dissertationsschrift mit dem Verhältnis von Wirtschaftswachstum und gesellschaftlicher Akzeptanz auf dem Weg zur deutschen Klimaneutralität. Dabei verbindet die Arbeit Ansätze der Ökologischen Ökonomik, des Ordoliberalismus und der Umweltökonomik. Die einzelnen Kapitel thematisieren: (1) die Stärke ökonomischer Multiperspektivität im Postwachstumsdiskurs, (2) eine Analyse von Modellannahmen deutscher Klimaneutralitätsszenarien, (3) das Konzept einer Sozialen Marktwirtschaft innerhalb planetarer Belastungsgrenzen sowie (4) die Ergebnisse deutschlandweiter Expert:inneninterviews zu den Hürden und Erfolgsfaktoren im kommunalen Klimaschutz. Die Dissertation zeigt aus unterschiedlichen Perspektiven, wie der klimapolitische Ordnungsrahmen der Bundesrepublik für ein zukunftsfähiges Wirtschaftssystem ausgestaltet sein sollte: widerspruchsfrei, effizient und konsistent zur klimawissenschaftlichen Datenlage.

    Servitization aus Risk-Governance-Perspektive – ein risikobasierter Ansatz für die Veränderung von Geschäftsmodellen
    (2026)
    Graversen, Michelle
    Der deutsche Anlagen- und Maschinenbau sieht sich einem zunehmenden internationalen Wettbewerbsdruck ausgesetzt. Unternehmen fokussieren sich daher vermehrt auf dienstleistungsbasierte Geschäftsmodelle, wie beispielsweise Produkt-Service-Systeme (PSS), welche Produkte mit Dienstleistungen verbinden. Die Implementierung eines PSS-Geschäftsmodells bietet die Aussicht auf eine verstärkte Kundenbindung, neue Erlösmodelle und nachhaltige Effizienzgewinne. Trotz dieser Vorteile ist die Verbreitung von PSS-Geschäftsmodellen noch begrenzt, da ihre Implementierung als komplex und riskant erachtet wird. Die vorliegende Untersuchung zeigt mithilfe einer systematischen Literaturanalyse und Experteninterviews wie die Risk Governance Unternehmen des Anlagen- und Maschinenbaus bei der erfolgreichen Implementierung eines PSS-Geschäftsmodells unterstützen kann.

    Antecedents and outcomes of hybrid entrepreneurship
    (2025-04-01)
    Demir, Cemre
    Today’s labor market dynamics offer more work flexibility than ever before, enabling various types of professional careers (Gänser-Stickler et al., 2022). Under these conditions, the phenomenon of hybrid entrepreneurship (HE) has emerged and is gaining increasing academic interest (e.g., Ardianti et al., 2022; Duhamel and St-Jean, 2023; Uriarte et al., 2023). HE is the engagement in self-employment activity while simultaneously holding a primary job in wage employment (Folta et al., 2010). The novelty of HE as a distinct research concept has resulted in a surge of publications in the past decade (Demir et al., 2022). This research has recognized that hybrid entrepreneurs defy classification as either self-employed or wage-employed individuals, instead forming a distinct group with unique antecedents (e.g., Thorgren et al., 2014), characteristics (e.g., Kurczewska et al., 2020; Maritz et al., 2023), dynamics (e.g., Schulz et al., 2016; Wennberg et al., 2006), and outcomes (e.g., Fini et al., 2017; Marshall et al., 2019). Recognizing the distinctive nature of hybrid entrepreneurs has unveiled their significant presence within the entrepreneurial landscapes of various countries (Bosma et al., 2008; Duhamel and St-Jean, 2023; Dvouletý and Bögenhold, 2023). Hybrid entrepreneurs are prevalent across diverse occupations and industries, notably in knowledge-intensive, innovative, and high-tech sectors (Fini et al., 2017; Folta et al., 2010; Markman et al., 2008; Marshall et al., 2019; Raffiee and Feng, 2014). Moreover, they can be found in all stages of an entrepreneurial carrier, especially in the periods of entry into and exit out of entrepreneurship (Folta et al., 2010; Raffiee and Feng, 2014). Despite its growing significance, HE remains underrepresented in scientific academic discourse. While existing research has provided both empirical and conceptual insights, knowledge about its distinct characteristics—particularly in comparison to full-time entrepreneurship—remains limited (Duhamel and St-Jean, 2023). Given the growing number of professionals actively opting for this form of entrepreneurship (Brändle and Kuckertz, 2022; Duhamel and St-Jean, 2023), the need for further investigation becomes evident. Additionally, hybrid entrepreneurs demonstrate significantly higher business survival rates compared to individuals transitioning directly from wage employment to entrepreneurship (Raffiee and Feng, 2014), further justifying the ongoing exploration of this phenomenon. To draw a more accurate picture of this entrepreneurial activity and the individuals involved, this dissertation explores and elucidates the concept of HE. In doing so, it takes as the focal point of its theoretical considerations the definition of HE outlined by Folta et al. (2010). According to this frequently used definition (e.g., Ferreira, 2020; Kuske et al., 2024; Marshall et al. 2019), the primary occupation must be wage employment, while self-employment is considered the secondary occupation. Apart from this condition, “hybrid entrepreneurship” is a relatively comprehensive term that does not consider time allocation between both jobs (Petrova, 2005, 2010a, 2010b, 2012) or the proportion of income generated from entrepreneurial activity (Mungaray and Ramirez-Urquidy, 2011). Yet this understanding of HE is nuanced enough to distinguish it from related concepts such as multiple job holding (MJH; Bouwhuis et al., 2017) and part-time entrepreneurship (Petrova, 2005, 2010a, 2010b, 2012). The initial study in this dissertation, a systematic literature review, demonstrates the significance of this delineation in facilitating conceptual and empirical progress in the research stream. The theoretical frameworks established in the second and third study within this dissertation examine the antecedents and outcomes of HE on the individual level. The analysis compares hybrid entrepreneurs with full-time entrepreneurs and places specific emphasis on periods of job transitions. In this context, HE is considered a two-staged process involving the initial transition from wage employment to HE, followed by the transition from HE to full-time entrepreneurship (Thorgren et al., 2016). The second study analyzes the impact of social capital by examining the existence and the occupational position of a hybrid entrepreneur’s life partner; this approach adopts a contextual perspective in considering the smallest micro-unit of the socio-economic environment, namely, the couple relationship (Özcan, 2011). The third study explores how HE, a status that enables an individual to test and learn about their entrepreneurial ability (Petrova, 2010a, 2010b; Wennberg et al., 2006) while requiring only modest initial commitments of time and capital (Raffiee and Feng, 2014), influences an individual’s well-being. Consequently, the study’s focus lies on the individual’s experience of satisfaction about starting and running an entrepreneurial venture (Wiklund et al., 2019). Well-being is an important outcome variable in entrepreneurship (Stephan, 2018), as it can influence persistence (e.g., Gorgievski et al., 2014; Patel and Thatcher, 2014; Wincent et al., 2008), firm performance (e.g., Ayala and Manzano, 2014), opportunity recognition (e.g., Gielnik et al., 2012; Rietveld et al., 2016), and work behavior (e.g., Foo et al., 2009; Laguna et al., 2016). The theoretical frameworks established in the second and third study aim to refine the profile of hybrid entrepreneurs, to reveal systematic differences between full-time and hybrid entrepreneurs, and to enhance the examination of causes and effects over time. Due to the novelty of the research stream, theory-driven data collection about HE is scarce (Kurczewska et al., 2020). Consequently, the first study—the systematic literature review—relies on already published studies as its foundational data source. The second and third study draw on data from the German Socio-Economic Panel (GSOEP), spanning the years 1984 to 2019. GSOEP is the largest wide-ranging representative panel study in Germany; it is conducted annually, with 30,000 respondents in approximately 10,000 households. It contains detailed information on demographics, employment, income, and satisfaction indicators. Furthermore, its panel structure allows researchers to exploit information for each year, to observe individuals over several waves, and thus to conduct longitudinal regression with fixed effects, as undertaken in the second and third study in this dissertation. The plausibility of the data is longitudinally validated, making it a reliable source for analysis. This dissertation has three main implications both for the theory and practice of HE. First, it emphasizes the critical importance of clearly distinguishing HE from related concepts through precise nomenclature and criteria. This distinction aids in evaluating the existing knowledge base and identifying areas where further research is needed. Secondly, the research findings indicate that for direct transitions, the presence of a life partner does not significantly affect the likelihood, for either gender, of entering entrepreneurship—although having a self-employed life partner appears to decrease that likelihood. For indirect transitions via HE, neither the presence nor the self-employment status of a life partner has a measurable effect. When analyzing genders separately, neither factor influences the direct transition. For indirect transitions via HE, having a life partner has no effect on either gender; however, the probability of indirect transition is higher for women with self-employed partners, an outcome not observed for men. Overall, the results indicate that the mere presence of a life partner does not significantly influence entrepreneurial transitions, whether direct or indirect. However, the self-employment status of the life partner does play a role. These results suggest that the influence of social capital within partnerships is nuanced and highlight the need to investigate additional factors that may affect job transitions. Finally, this dissertation provides evidence that different types of job transitions within the entrepreneurial context have varying effects on life, job, and leisure time satisfaction, at varying intensities. The findings show that transitioning from wage employment to HE is associated with a decline in job and life satisfaction, while leisure time satisfaction remains unaffected. Notably, the negative impact is significantly greater for job satisfaction than for life and leisure time satisfaction. In contrast, moving from wage employment to full-time entrepreneurship has a positive effect on job satisfaction but does not influence life or leisure time satisfaction. Also here, job satisfaction was found to be the most significantly affected outcome. These results highlight that well-being outcomes are distinctively shaped by the specific pathways into entrepreneurship. In conclusion, all three studies covered by this dissertation offer valuable insights by outlining the current state of knowledge and deepening the understanding of entrepreneurial behavior and the impact of hybrid entrepreneurs. This knowledge holds practical utility. Individuals engaged in HE can leverage these results to gain insights into the opportunities and risks associated with the hybrid path. For instance, they should be mindful of the potential dual burden that comes with this choice and its possible negative effects on job satisfaction. Additionally, although HE might allow for greater flexibility and a more mindful use of leisure time, it may not necessarily enhance leisure time satisfaction due to time constraints. Moreover, policies aimed at promoting entrepreneurship can draw on these studies to create tailored economic opportunities and legal frameworks. Since having a self-employed life partner decreases an individual’s inclination to pursue entrepreneurship directly, indicating a tendency toward risk diversification, policymakers could consider providing financial assistance, such as tax incentives or subsidies for self-employed couples, to help mitigate risk and uncertainty. Policy interventions are especially important given that hybrid entrepreneurs are more responsive than full-time entrepreneurs to regulatory changes (Schulz et al., 2016). Additionally, when the strength of downside risk aversion—also referred to as prudence—in entrepreneurship is sufficiently high, hybrid entrepreneurs tend to allocate more time to their side businesses during periods of increased risk as a precautionary measure to mitigate potential losses (Benitez et al., 2024). However, despite this increased time investment, elevated opportunity costs reduce hybrid entrepreneurs’ willingness to sustain their businesses during crises (Block et al., 2022). Because of this sensitivity, policy interventions strategically designed to ensure the resilience and continuity of hybrid businesses have the potential for significant success. In summary, this dissertation will assist researchers and practitioners in gaining insights into the unique dynamics of HE. On the individual level and when compared to self-employed individuals, it illuminates the intricate interplay of factors guiding hybrid entrepreneurs into this entrepreneurial journey and explores the consequences for their well-being. Thus, it fosters a more nuanced comprehension of the evolving landscape of entrepreneurship.

    Deliberative Democracy and the Political Corporation - Critical Perspectives on Transparency and Regulation in the Context of Business and Human Rights
    (2026-07-09)
    Schneider, Oliverorcid-logo
    This dissertation investigates how companies contribute to corporate accountability for human rights through their interaction with society across three discursive arenas: stakeholder engagement, formal disclosure, and public governance. Drawing on Habermas’ theory of communicative action and deliberative democracy, it comprises four independent papers that explore the interconnectedness of these levels. The first paper presents a structured literature review, revealing that business and human rights remain a niche, highly fragmented topic in academic accounting discourse. The second paper utilizes critical discourse analysis to evaluate corporate reporting on civil society engagement. It reveals significant communicative distortions across Habermasian validity claims, notably through dispersed information (comprehensibility) , marginalization of vulnerable value-chain actors (legitimacy) , manipulative connotative language (sincerity) , and unassured multiple reporting media (truth). The third paper validates these structural deficiencies through interviews with European experts, highlighting that incomplete data and brand-management practices severely undermine corporate transparency. The fourth paper examines the discursive legitimacy of the EU’s Corporate Sustainability Due Diligence Directive (CSDDD). It traces how a balanced provisional agreement was systematically watered down in its final 2025 text and the subsequent Omnibus initiative due to opaque lobbying by a small number of powerful economic actors. Ultimately, the dissertation warns of a European business and human rights crisis. Voluntary, market-based steering is ineffective due to distorted communication, while regulatory correctives are captured by corporate power. The author recommends viewing transparency and behavioral duties as complementary components of a "smart policy mix" , alongside reforms in management education and democratic lobbying practices.

    Servitization aus Risk-Governance-Perspektive – ein risikobasierter Ansatz für die Veränderung von Geschäftsmodellen
    (2026)
    Graversen, Michelle
    The German plant and machinery manufacturing sector is under increasing competitive pressure from abroad. Companies are focusing more and more on service-based business models, such as Product-Service Systems (PSS), which integrate products and services. Implementing a PSS business model can strengthen customer loyalty, generate new revenue streams and achieve sustainable efficiency gains. Despite these potential advantages, adoption of PSS business models remains limited as implementation is considered complex and risky. This study uses a systematic literature review and expert interviews to explore how risk governance can support plant and machinery manufacturing companies in successfully implementing a PSS business model.

    Daily Encounters with AI: An Inquiry into Users’ Sensemaking
    (2025-07-30)
    Alizadeh, Fatemehorcid-logo
    We live in times of rapid change, where unprecedented and unexpected events unfold with increasing speed and complexity, often disrupting familiar patterns and norms. In the midst of this uncertainty, AI plays a growing role, shaping how we interact, work, and live. To navigate such ambiguity, humans rely on sensemaking —a process of interpreting the unknown, settling on plausible explanations, and adapting their actions accordingly. Despite AI’s growing influence on nearly every aspect of life, studies repeatedly show that users often have a limited understanding of it, leading to misconceptions and unrealistic expectations. This lack of understanding not only results in frustration when AI systems fail to meet users’ needs but also hinders effective interaction and collaboration with these technologies. This dissertation views AI as a socio-technical umbrella term to explore how users make sense of it across three application domains: AI-assisted decisionmaking, AI-mediated social platforms, and agentic AI technologies. Guided by three research questions, it focuses on (1) how users make sense of AI in everyday encounters, (2) the empowerment needs that arise from these interactions, and (3) how design can support sensemaking and foster user agency. Recognizing the importance of context and the situated nature of sensemaking, this work combines various qualitative methods, such as semi-structured interviews, role-playing workshops, and experience sampling. Building on Weick’s sensemaking framework, the findings reveal that sensemaking of AI shares familiar characteristics—it’s enactive, driven by plausibility, inherently social, and often triggered by unexpected events. But AI sensemaking also has unique aspects, such as the influence of AI "folk concepts"—users’ assumptions and expectations about AI shaped by cultural narratives and societal definitions. These perceptions are also influenced by human traits like trust and intelligence and vary depending on stakeholder roles. AI sensemaking not only guides users’ actions but also informs counteractions—how people push back against or adapt to algorithmic systems. To empower users, this research takes a holistic approach, exploring their needs along three dimensions: feeling, knowing, and doing. It highlights how users’ sensemaking is influenced by both episodic power—arising from immediate, specific interactions—and systemic power, which operates at a structural level through institutional norms and opaque algorithmic designs. For designing AI systems that better support users’ sensemaking, the dissertation emphasizes two critical aspects. First, it frames sensemaking as an interactional element, suggesting that AI systems should foster continuous, context-specific engagement by helping users build competencies. Second, it stresses the importance of diversifying user participation in the design process. Involving users as co-creators and knowledge-makers empowers them to engage not just in sensemaking, but also in sense-unmaking, sense-giving, and sense-breaking—creating a more collaborative and inclusive design process that addresses both individual needs and systemic challenges. Finally, this dissertation argues for moving beyond Weick’s retrospective sensemaking framework to apply the concept of prospective sensemaking in the context of AI. This approach emphasizes designing systems that not only help users make sense of past interactions but also enable them to anticipate, adapt to, and shape the uncertainties inherent in their ongoing and future engagements with AI technologies.

    Die Memefication der privaten Geldanlage - eine kompetenzorientierte Untersuchung unter Berücksichtigung individueller Risikopräferenzen
    (2025)
    Dielmann, Jan-Philipp
    As an omnipresent element of digital communication, internet memes have also entered the realm of retail investing. Narratives that trivialize or ironically frame financial risks and losses meet a young generation of investors who increasingly turn to social media for financial information, yet often display gaps in financial literacy. The lack of experience and knowledge, combined with the low-barrier opportunities for capital market participation provided by trading apps, raises the question of how meme-based communication influences individual investment decisions. This dissertation uses an experimental design to investigate the impact of financial memes on individual risk preferences and outlines implications for the financial education and communication strategies of financial service providers.

    Economic Theory of Lobbying: Groups and Innovation
    (2025)
    Bolin Simon, Theo 
    This dissertation critically evaluates political-economic research on lobbying and contrasts isolated welfare-economic theory with a contextual theory based on the roots of political economy and ordoliberalism. It argues that it is necessary to revisit the question of the nature of lobbying and to bring social interactions back to the forefront of the analysis. The dissertation is primarily rooted in political economy, ordoliberalism, entrepreneurship research, and contextual economics. The first two articles of the dissertation take a systems theory perspective on lobbying and make a theoretical contribution to the impact of lobbying at the system and actor levels. Furthermore, lobbying rules are found to place a strong focus on negative regulation (prohibitions) and increasing transparency, but at the same time to lack ideas with regard to positive, enabling rules of lobbying. Therefore, the existing set of rules cannot sufficiently promote the productive characteristics of lobbying. In the third article, initial drafts for such rules are developed.
