T1 - A paradox perspective on the interactive effects of visionary and empowering leadership JF - Organizational Behavior and Human Decision Processes N2 - In a multi-source, lagged design field study of 197 leader-follower dyads, we test a model that predicts positive interactive effects of visionary and empowering leadership on follower performance. Based on the paradox perspective, we argue that visionary and empowering leadership are synergistic in that their combination enables leaders to address a key paradox inherent to leader behavior identified by Waldman and Bowen (2016): Maintaining control while simultaneously letting go of control. We argue that visionary leadership addresses the former and empowering leadership addresses the latter pole of this pair of opposites. Hence, in line with paradox thinking, we posit that leaders will engender more positive effects on follower performance when they enact visionary and empowering leadership behaviors simultaneously and adopt a "both-and" approach, rather than focus on one of these behaviors without the other. Our results support our hypothesized interactive effect of visionary and empowering leadership on goal clarity, as well as a conditional indirect effect such that goal clarity mediates the interactive effect of visionary and empowering leadership on individual follower performance.

The study assumes that people will only lower their level of consumption if doing so does not also lower personal wellbeing. More precisely, this research investigates how specific subtypes of sustainable anticonsumption (e.g., voluntary simplicity, collaborative consumption, and debt-free living) relate to different states of consumer's wellbeing (e.g., financial, psychosocial, and subjective wellbeing). This work also examines whether consumer empowerment can improve personal wellbeing and strengthen the anticonsumption wellbeing relationship. The results show that voluntarily foregoing consumption does not reduce wellbeing and consumer empowerment plays a significant role in supporting sustainable pathways to consumer wellbeing. This study reasons that empowerment improves consumer sovereignty, but may be detrimental for consumers heavily concerned about debt-free living. The present investigation concludes by proposing implications for public and consumer policymakers wishing to promote appropriate sustainable (anticonsumption) pathways to consumer wellbeing.

ER - TY - JOUR A1 - Ziesemer, Florence A1 - Hüttel, Alexandra A1 - Balderjahn, Ingo T1 - Anti-Consumption JF - Sustainability N2 - Transcending the conventional debate around efficiency in sustainable consumption, anti-consumption patterns leading to decreased levels of material consumption have been gaining importance. Change agents are crucial for the promotion of such patterns, so there may be lessons for governance interventions that can be learnt from the every-day experiences of those who actively implement and promote sustainability in the field of anti-consumption. Eighteen social innovation pioneers, who engage in and diffuse practices of voluntary simplicity and collaborative consumption as sustainable options of anti-consumption share their knowledge and personal insights in expert interviews for this research. Our qualitative content analysis reveals drivers, barriers, and governance strategies to strengthen anti-consumption patterns, which are negotiated between the market, the state, and civil society. Recommendations derived from the interviews concern entrepreneurship, municipal infrastructures in support of local grassroots projects, regulative policy measures, more positive communication to strengthen the visibility of initiatives and emphasize individual benefits, establishing a sense of community, anti-consumer activism, and education. We argue for complementary action between top-down strategies, bottom-up initiatives, corporate activities, and consumer behavior. The results are valuable to researchers, activists, marketers, and policymakers who seek to enhance their understanding of materially reduced consumption patterns based on the real-life experiences of active pioneers in the field.

BT - The Long-Term Business and Innovation Potential of Subsidized Start-Ups out of Unemployment T2 - CEPA Discussion Papers N2 - From an active labor market policy perspective, start-up subsidies for unemployed individuals are very effective in improving long-term labor market outcomes for participants. From a business perspective, however, the assessment of these public programs is less clear since they might attract individuals with low entrepreneurial abilities and produce businesses with low survival rates and little contribution to job creation, economic growth, and innovation. In this paper, we use a rich data set to compare participants of a German start-up subsidy program for unemployed individuals to a group of regular founders who started from nonunemployment and did not receive the subsidy. The data allows us to analyze their business performance up until 40 months after business formation. We find that formerly subsidized founders lag behind not only in survival and job creation, but especially also in innovation activities. The gaps in these business outcomes are relatively constant or even widening over time. Hence, we do not see any indication of catching up in the longer run. While the gap in survival can be entirely explained by initial differences in observable start-up characteristics, the gap in business development remains and seems to be the result of restricted access to capital as well as differential business strategies and dynamics. Considering these conflicting results for the assessment of the subsidy program from an ALMP and business perspective, policy makers need to carefully weigh the costs and benefits of such a strategy to find the right policy mix.

Limited resources, missing expertise and absolute uncertainty call entrepreneurs to strongly rely on their cognition in searching for a promising BM. However, as prior studies have examined cognitive search activities in isolation and neglected cognitive differences, explanations of how cognitive factors affect the BM process and outcomes are thus far insufficient. Addressing the overall question of how BMs emerge, the dissertation contributes to the cognitive perspective in entrepreneurship and BM research. Building on the dual-process theory from cognitive psychology, the micro-foundations of managerial decision-making and insights from framing literature, this dissertation explicitly investigates the impacts of different cognitive dispositions, search activities and visual framing effects. The core assumption is that cognitive dispositions and entrepreneurs’ searches for information determine their BM decision-making. Furthermore, BM visualisations have become popular instruments with which to explain and manage today’s complex business interactions. As they abstract from reality, they can also unfold impacts on the cognitive processes. This dissertation offers new explanations to these aspects and consists of three studies and one reflective article. The first study explores the impacts of differences in search activities and cognitive dispositions in a qualitative study with 70 entrepreneurship students. The second qualitative study explores the cognitive impacts of 103 BM visualisations. Third, a quantitative PLS-SEM experiment with 197 entrepreneurs illuminates the link between BM visualisations and cognition. The reflective article expresses the results’ meaning for the teaching of BMs. In sum, the studies have resulted in a new theory of stabilising factors explaining how cognitive dispositions, search activities and visual framing determine entrepreneurs’ decisions to imitate or deviate from existing BMs. It indicates that the decision depends on the context-dependent strategic orientation and cognitive disposition-dependent cognitive safety, that is the correspondence between characteristics of cognitive dispositions and search activities. Moreover, the studies identified five visual framing effects that are independent of cognitive dispositions and prior experiences. This provides fertile contributions to the literature on BM methods and how BM visualisations affect decisions. Most importantly, BM visualisations provide an emotionally stabilising function to rational entrepreneurs, a cognitively stabilising function to experiential participants and do not affect indifferent participants in general. N2 - Die Suche nach vielversprechenden Geschäftsmodellen (GMen) ist für jedes gewinn-orientierte Unternehmen essenziell. Die Suche fordert vor allem Neugründer heraus. Aufgrund begrenzter Ressourcen, fehlender Erfahrungen und hoher Unsicherheit beruht deren Suche stark auf deren Kognition. Die bisherigen Erklärungen, wie sich kognitive Faktoren auf GM-Prozesse und -Ergebnisse auswirken, sind jedoch unzureichend. Diese vernachlässigen indivi¬duelle Unterschiede und betrachten ausschließlich einzelne, kognitive Suchaktivitäten. Diese Dissertation befasst sich folglich mit der allgemeinen Frage, wie GMe entstehen. Aufbauend auf der Dual-Process-Theorie, den Mikro-Grundlagen der Entscheidungsfindung und Framingeffekten werden die Auswirkungen verschiedener kognitiver Dispositionen, Suchaktivitäten und visueller Framingeffekte auf GM-Prozesse und -Ergebnisse untersucht. Grundlegend bestimmen die kognitive Disposition und Suchaktivitäten den Prozess. Darüber hinaus können auch GM-Visualisierungen Einflüsse entfalten, da sie von der Realität abstrahieren. Die Beantwortung der Frage, welche Einflüsse sie ausüben, ist bedeutend, da sie genutzt werden, um heutige, komplexe Geschäftsbeziehungen zu erklären und zu steuern. Die Dissertation bietet neue Erklärungen zu diesen Aspekten und besteht aus drei Studien und einem Reflexionsartikel. Die erste Studie untersucht die Auswirkungen von Unterschieden bei Suchaktivitäten und kognitiven Dispositionen in einer qualitativen Studie mit 70 Entrepre¬neurship-Studierenden. Die zweite, qualitative Studie untersucht die kognitiven Auswirkungen von 103 GM-Visualisierungen. Drittens beleuchtet ein quantitatives PLS-SEM-Experiment mit 197 Gründern die Beziehung zwischen GM-Visualisierungen und Kognition. Der Reflexions¬artikel beschreibt die Bedeutung der Ergebnisse für die GM-Lehre. Zusammenfassend trägt diese Dissertation zur kognitiven Perspektive der GM- und Ent¬repreneurship-Forschung bei. Die Ergebnisse eröffnen eine neue theoretische Erklärung und erweitern das Wissen über GM-Methoden. Sta¬bilisierende Faktoren wie der Zusammenhang zwischen Disposition und Suchaktivitäten sind Grundvoraussetzung für Gründer, um neuartige GMe zu entwickeln. Diese neue Erkenntnis wird durch das neue Konzept, kognitive Sicherheit, als kontext-unabhängige GM-Auswirkung be¬schrieben. Die strategische Orientierung wirkt sich kontextabhängig aus. Des Weiteren wurden fünf visuelle Framingeffekte identifiziert, die unabhängig von Disposition und Vorwissen Entscheidungen beeinflussen. Am bedeutendsten zeigt sich, dass GM-Visualisierungen emotional-stabilisierende Auswirkungen auf rationale und kognitiv-stabilisierende Auswirkungen auf erfahrungsgetriebene Gründer haben.

The impetus for proposing this specific PSG was the growing importance of the local level within the multi-level governance system in the European Union and most of its member states. The PSG 4 acts as a European network of research activities inside and outside EGPA, producing joint publications and organising scientific debates on many problems of the development of municipalities and local authorities. Our focus was on discussing both how to improve democracy by increased participation and deliberation, and how to secure provision of services in an efficient way in developed welfare societies. This includes analysing several forms of administrative changes and reforms at the local level and research of representative, direct and cooperative democracy at local level in a cross-European comparison.
