In recent years, entire industries and their participants have been affected by disruptive technologies, resulting in dramatic market changes and challenges to firm’s business logic and thus their business models (BMs). Firms from mature industries are increasingly realizing that BMs that worked successfully for years have become insufficient to stay on track in today’s “move fast and break things” economy. Firms must scrutinize the core logic that informs how they do business, which means exploring novel ways to engage customers and get them to pay. This can lead to a complete renewal of existing BMs or innovating completely new BMs.
BMs have emerged as a popular object of research within the last decade. Despite the popularity of the BM, the theoretical and empirical foundation underlying the concept is still weak. In particular, the innovation process for BMs has been developed and implemented in firms, but understanding of the mechanisms behind it is still lacking. Business model innovation (BMI) is a complex and challenging management task that requires more than just novel ideas. Systematic studies to generate a better understanding of BMI and support incumbents with appropriate concepts to improve BMI development are in short supply. Further, there is a lack of knowledge about appropriate research practices for studying BMI and generating valid data sets in order to meet expectations in both practice and academia.
This paper-based dissertation aims to contribute to research practice in the field of BM and BMI and foster better understanding of the BM concept and BMI processes in incumbent firms from mature industries. The overall dissertation presents three main results. The first result is a new perspective, or the systems thinking view, on the BM and BMI. With the systems thinking view, the fuzzy BM concept is clearly structured and a BMI framework is proposed. The second result is a new research strategy for studying BMI. After analyzing current research practice in the areas of BMs and BMI, it is obvious that there is a need for better research on BMs and BMI in terms of accuracy, transparency, and practical orientation. Thus, the action case study approach combined with abductive methodology is proposed and proven in the research setting of this thesis. The third result stems from three action case studies in incumbent firms from mature industries employed to study how BMI occurs in practice. The new insights and knowledge gained from the action case studies help to explain BMI in such industries and increase understanding of the core of these processes.
By studying these issues, the articles complied in this thesis contribute conceptually and empirically to the recently consolidated but still increasing literature on the BM and BMI. The conclusions and implications made are intended to foster further research and improve managerial practices for achieving BMI in a dramatically changing business environment.
Since spring 2014 the relations between the EU and Russia are stuck in an Ice Age. From a Western point of view, especially the annexation of Crimea by Russia and the intervention in the conflict in Ukraine are responsible. The EU has frozen their relations to Russia and applied sanctions against it. Russia reacted in the same way. Can this vicious circle be broken without betraying the values of the EU? This book presents the analysis and ideas of social scientists from Germany, Poland and Russia. The reasons for this crisis are seen quite differently but all try to find a way out of the current confrontation.
Ivo Lormes zeigt, dass der Kommunalisierungstrend in der
Energieversorgung als Indikator eines zukunftsgerichteten Zeitalterskommunal(-energie-)wirtschaftlicher Betätigung gedeutet werden kann.
Die sich dabei manifestierende neue Qualität institutioneller Arrangements interpretiert er als Indiz für eine ‚Gewährleistungskommune 2.0‘. Neben einer Analyse der seit 2005 in Deutschland erfolgten Stadtwerke-Gründungen werden in seinem Buch erstmals die im Rahmen dieser Kommunalisierungen ablaufenden politischen Prozesse fallstudienvergleichend untersucht. Dadurch wird eine systematische Ermittlung der Einflussfaktoren zu der Frage ermöglicht, warum manche Kommunen ihre Energieversorgung kommunalisieren und andere nicht.
This cumulative dissertation contains four self-contained articles which are related to EU regional policy and its structural funds as the overall research topic. In particular, the thesis addresses the question if EU regional policy interventions can at all be scientifically justified and legitimated on theoretical and empirical grounds from an economics point of view. The first two articles of the thesis (“The EU structural funds as a means to hamper migration” and “Internal migration and EU regional policy transfer payments: a panel data analysis for 28 EU member countries”) enter into one particular aspect of the debate regarding the justification and legitimisation of EU regional policy. They theoretically and empirically analyse as to whether regional policy or the market force of the free flow of labour (migration) in the internal European market is the better instrument to improve and harmonise the living and working conditions of EU citizens. Based on neoclassical market failure theory, the first paper argues that the structural funds of the EU are inhibiting internal migration, which is one of the key measures in achieving convergence among the nations in the single European market. It becomes clear that European regional policy aiming at economic growth and cohesion among the member states cannot be justified and legitimated if the structural funds hamper instead of promote migration. The second paper, however, shows that the empirical evidence on the migration and regional policy nexus is not unambiguous, i.e. different empirical investigations show that EU structural funds hamper and promote EU internal migration. Hence, the question of the scientific justification and legitimisation of EU regional policy cannot be readily and unambiguously answered on empirical grounds. This finding is unsatisfying but is in line with previous theoretical and empirical literature. That is why, I take a step back and reconsider the theoretical beginnings of the thesis, which took for granted neoclassical market failure theory as the starting point for the positive explanation as well as the normative justification and legitimisation of EU regional policy. The third article of the thesis (“EU regional policy: theoretical foundations and policy conclusions revisited”) deals with the theoretical explanation and legitimisation of EU regional policy as well as the policy recommendations given to EU regional policymakers deduced from neoclassical market failure theory. The article elucidates that neoclassical market failure is a normative concept, which justifies and legitimates EU regional policy based on a political and thus subjective goal or value-judgement. It can neither be used, therefore, to give a scientifically positive explanation of the structural funds nor to obtain objective and practically applicable policy instruments. Given this critique of neoclassical market failure theory, the third paper consequently calls into question the widely prevalent explanation and justification of EU regional policy given in static neoclassical equilibrium economics. It argues that an evolutionary non-equilibrium economics perspective on EU regional policy is much more appropriate to provide a realistic understanding of one of the largest policies conducted by the EU. However, this does neither mean that evolutionary economic theory can be unreservedly seen as the panacea to positively explain EU regional policy nor to derive objective policy instruments for EU regional policymakers. This issue is discussed in the fourth article of the thesis (“Market failure vs. system failure as a rationale for economic policy? A critique from an evolutionary perspective”). This article reconsiders the explanation of economic policy from an evolutionary economics perspective. It contrasts the neoclassical equilibrium notions of market and government failure with the dominant evolutionary neo-Schumpeterian and Austrian-Hayekian perceptions. Based on this comparison, the paper criticises the fact that neoclassical failure reasoning still prevails in non-equilibrium evolutionary economics when economic policy issues are examined. This is surprising, since proponents of evolutionary economics usually view their approach as incompatible with its neoclassical counterpart. The paper therefore argues that in order to prevent the otherwise fruitful and more realistic evolutionary approach from undermining its own criticism of neoclassical economics and to create a consistent as well as objective evolutionary policy framework, it is necessary to eliminate the equilibrium spirit. Taken together, the main finding of this thesis is that European regional policy and its structural funds can neither theoretically nor empirically be justified and legitimated from an economics point of view. Moreover, the thesis finds that the prevalent positive and instrumental explanation of EU regional policy given in the literature needs to be reconsidered, because these theories can neither scientifically explain the emergence and development of this policy nor are they appropriate to derive objective and scientific policy instruments for EU regional policymakers.
It is the intention of this study to contribute to further rethinking and innovating in the Microcredit business which stands at a turning point – after around 40 years of practice it is endangered to fail as a tool for economic development and to become a doubtful finance product with a random scope instead. So far, a positive impact of Microfinance on the improvement of the lives of the poor could not be confirmed. Over-indebtment of borrowers due to the pre-dominance of consumption Microcredits has become a widespread problem. Furthermore, a rising number of abusive and commercially excessive practices have been reported.
In fact, the Microfinance sector appears to suffer from a major underlying deficit: there does not exist a coherent and transparent understanding of its meaning and objectives so that Microfinance providers worldwide follow their own approaches of Microfinance which tend to differ considerably from each other.
In this sense the study aims at consolidating the multi-faced and very often confusingly different Microcredit profiles that exist nowadays. Subsequently, in this study, the Microfinance spectrum will be narrowed to one clear-cut objective, in fact away from the mere monetary business transactions to poor people it has gradually been reduced to back towards a tool for economic development as originally envisaged by its pioneers.
Hence, the fundamental research question of this study is whether, and under which conditions, Microfinance may attain a positive economic impact leading to an improvement of the living of the poor.
The study is structured in five parts: the three main parts (II.-IV.) are surrounded by an introduction (I.) and conclusion (V.). In part II., the Microfinance sector is analysed critically aiming to identify the challenges persisting as well as their root causes. In the third part, a change to the macroeconomic perspective is undertaken in oder to learn about the potential and requirements of small-scale finance to enhance economic development, particularly within the economic context of less developed countries. By consolidating the insights gained in part IV., the elements of a new concept of Microfinance with the objecitve to achieve economic development of its borrowers are elaborated.
Microfinance is a rather sensitive business the great fundamental idea of which is easily corruptible and, additionally, the recipients of which are predestined victims of abuse due to their limited knowledge in finance. It therefore needs to be practiced responsibly, but also according to clear cut definitions of its meaning and objectives all institutions active in the sector should be devoted to comply with. This is especially relevant as the demand for Microfinance services is expected to rise further within the years coming. For example, the recent refugee migration movement towards Europe entails a vast potential for Microfinance to enable these people to make a new start into economic life. This goes to show that Microfinance may no longer mainly be associated with a less developed economic context, but that it will gain importance as a financial instrument in the developed economies, too.
Selbstverständnis und Image der Unternehmensberatung, das Bewerbern, Mitarbeitern und Kunden gleichermaßen Wissensvorsprung durch Ballung der besten Köpfe verspricht, scheinen sowohl für den Berater als auch den Kunden einen Erfolgsfaktor einzunehmen. Die Karriere des Unternehmensberaters wird im Vergleich zu anderen Branchen durch eine starke Formalisierung anhand von Kompetenzen und Entwicklungspfaden begleitet. Talentgewinnung und -entwicklung sind dabei Kernaufgaben des Personalmanagements, das gerade aufgrund seiner kompetenzbasierten Instrumente und formalistischen Strukturen als Erfolgsfaktor gilt. Die Analyse der Autorin setzt beim Personalmanagement der Unternehmensberatung an. Auffällig erscheinen dabei zunächst ähnliche Strukturen und Instrumente zur Talentidentifikation und -entwicklung, die für eine gesamte Branche charakteristisch sind. Speziell für Professional Service Firms ist der Mitarbeiter die entscheidende ökonomische Größe in der Leistungserbringung. Der Kunde beurteilt die Unternehmensleistung im Zusammenspiel mit seinem Kontakt zum Mitarbeiter, der maßgeblich für die Leistungserbringung und Qualitätssicherung verantwortlich ist. Der Analysefokus liegt deshalb im Personalmanagement von Unternehmensberatungen als Teil der Professional Service Firms und wird vor dem Hintergrund systemtheoretischer Überlegungen beleuchtet. Eckpfeiler des Systems zeigen sich insbesondere in Form von branchenüblichen Rekrutierungsstrategien, der formalistischen Leistungsbeurteilung, dem vergleichsweise steilen Karriereverlauf sowie anhand überdurchschnittlicher Gehälter. Hat die Unternehmensberatung die Qualifizierung und Entwicklung ihrer Mitarbeiter zum Erfolgsfaktor gemacht? Die Autorin analysiert, ob das Personalmanagement und seine Verfahren berechtigterweise als Erfolgsfaktor einer Branche gelten, welche Faktoren den wirtschaftlichen Erfolg der Branche beeinflussen und welche Grenzen die Nutzenanalyse in Bezug auf die Beratungsleistung erfährt. ?
Die schulische Berufswahlvorbereitung versäumt es, Jugendliche auf die Wahl des Ausbildungsbetriebs vorzubereiten. Sie thematisiert nur die Berufswahl, obwohl die Entscheidung für eine betriebliche Ausbildung immer auch die Entscheidung für einen Ausbildungsbetrieb voraussetzt. Für die Ausbildungszufriedenheit und den -erfolg ist diese Betriebswahl zentral. Angesichts des Mismatchs am Ausbildungsmarkt ist das Thema hochrelevant.
Aus welchen Gründen entscheiden sich Jugendliche für einen Ausbildungsbetrieb? Diese Frage untersucht die vorliegende Arbeit aus prospektiver Sicht in narrativen Einzelinterviews mit 52 Schülerinnen und Schülern der 9. und 10. Klassenstufen verschiedener Schultypen und aus retrospektiver Sicht in vier multipel eingebetteten Mehrfallstudien mit 17 Auszubildenden aus vier Betrieben und in acht Berufen – jeweils in Brandenburg und Berlin. Theoretisch nähert sich diese Arbeit dem Thema über psychologische, soziologische und wirtschaftswissenschaftliche sowie interdisziplinäre Berufswahltheorien an, dem operativen Modell der Betriebswahl sowie dem hier neu entwickelten Modell der Ausbildungswahl als Entscheidungsprozess, das die beiden Wahlkomponenten Betrieb und Beruf vereint.
Drei zentrale Erkenntnisse kennzeichnen das Ergebnis der vorliegenden Arbeit:
1. Jugendliche beschäftigen sich mit der Wahl des Ausbildungsbetriebs und berücksichtigen vor allem emotionale Gründe. Diese variieren von Person zu Person.
2. Wichtigste Entscheidungsgründe für den Ausbildungsbetrieb sind der persönliche Eindruck, die inhaltliche Solidität, der Ort, das Betriebsklima, Kontakte ins Unternehmen, Perspektiven und die Bezahlung.
3. Jugendliche mit Mittlerem Schulabschluss achten besonders auf die Perspektiven nach Ausbildungsende.
Die wenigen anderen Studien zur Entscheidung für den Ausbildungsbetrieb gehen auf den am häufigsten genannten Entscheidungsgrund persönlicher Eindruck nicht ein. Auch kommen sie zu uneinheitlichen Schlüssen, für welche Personengruppe der Entscheidungsgrund Perspektiven besonders relevant ist. Es bedarf zusätzlicher Studien, um die Ergebnisse zu überprüfen und ihre statistische Verteilung in größeren Bevölkerungsgruppen zu untersuchen sowie eine belastbare, ganzheitliche Theorie zur Ausbildungswahl zu entwickeln.
I examine the determinants of both perceived inflation and unemployment in one single survey and include Big Five traits in the analysis. This is the first survey on this topic in Germany. My sample consists of 1771 students from different fields and levels. Using PhD students’ estimates as a reference, I create categories for underestimation and overestimation of both variables. Multinomial logit regressions show that females overestimate both variables. Education and news consumption reduce misestimation. A higher level of Neuroticism is related with a higher probability to overestimate unemployment. Overstating (understating) one indicator is associated with overstating (understating) the other.
The positive aspects of open innovation projects are widely discussed in innovation management research and practice by means of case studies and best practices. However, enterprises, particularly small and medium-sized enterprises (SMEs) also face miscellaneous challenges in open innovation practice, leading to uncertainty and even renunciation of open innovation project participation. Thus, it is essential for SMEs to find the right balance between possible positive effects and negative consequences - the latter being the less studied "dark sides" of open innovation. However, appropriate methods of finding this balance are still lacking. In this article, we discuss the assessment of open innovation project participation by presenting a weighing and decision process framework as a conceivable solution approach. The framework includes an internal, external, and integrated analysis as well as a recommendation and decision phase. Piece by piece, we investigate the current situation and the innovation goals of the enterprise as an initial point for a decision for or against engaging in open innovation. Furthermore, we discuss the development of a software tool that automatically applies this framework and allows self-assessment by SMEs.
This article addresses security and privacy issues associated with storing data in public cloud services. It presents an architecture based on a novel secure cloud gateway that allows client systems to store sensitive data in a semi-trusted multi-cloud environment while providing confidentiality, integrity, and availability of data. This proxy system implements a space-efficient, computationally-secure threshold secret sharing scheme to store shares of a secret in several distinct cloud datastores. Moreover, the system integrates a comprehensive set of security measures and cryptographic protocols to mitigate threats induced by cloud computing. Performance in practice and code quality of the implementation are analyzed in extensive experiments and measurements. (C) 2016 Elsevier B.V. All rights reserved.
Background: Cloud computing promises to essentially improve healthcare delivery performance. However, shifting sensitive medical records to third-party cloud providers could create an adoption hurdle because of security and privacy concerns. Methods: We empirically investigate our research question by a survey with over 260 full responses. For the setting with a high confidentiality assurance, we base on a recent multi-cloud architecture which provides very high confidentiality assurance through a secret-sharing mechanism: Health information is cryptographically encoded and distributed in a way that no single and no small group of cloud providers is able to decode it.
This article contributes to the debate on the use of performance information in the context of public sector performance management. Based on case studies, the authors analyze the appropriateness of the performance information provided in the newly established performance budgets of municipalities in Germany and Italy. They also examine the interest of politicians and senior managers in using such information for decision-making and monitoring within the municipal budget cycle. They find that the use of performance information is generally quite modest, and that the interest of different local actors varies to a great extent. Politicians are generally less interested in such information than top managers, particularly chief financial officers. The results are discussed by applying a theoretical framework based on institutional and legitimacy theories, and are compared with the literature on performance information use.
Previous research on open innovation (OI) has primarily focused on the organisational level of R&D intensive industries. With this paper, we contribute to research on the individual level of analysis by analysing specific perspectives in the context of creative industries. Our study is based on 36 interviews with Haute cuisine chefs in France, Germany, Great Britain, Italy, Spain, Sweden, and Switzerland listed in the 2012 Michelin Guide. Building on the OI capability concept, our results demonstrate that chefs use absorptive and desorptive capacity (AC, DC) as means to generate and market culinary innovations, respectively. Moreover, we found that chefs almost exclusively rely on their own inventive and innovative capabilities in the early stages of the culinary innovation process. In subsequent phases, however, chefs increasingly integrate other sources such as employees, suppliers, and guests. Our study contributes to the literature in two ways. First, we research the individual level within the OI process, and second, we provide insight into OI practices in the creative industries.
This article is a response to calls in prior research that we need more longitudinal analyses to better understand the foundations of PSM and related prosocial values. There is wide agreement that it is crucial for theory building but also for tailoring hiring practices and human resource development programs to sort out whether PSM-related values are stable or developable. The article summarizes existent theoretical expectations, which turn out to be partially conflicting, and tests them against multiple waves of data from the German Socio-Economic Panel Study which covers a time period of 16 years. It finds that PSM-related values of public employees are stable rather than dynamic but tend to increase with age and decrease with organizational membership. The article also examines cohort effects, which have been neglected in prior work, and finds moderate evidence that there are differences between those born during the Second World War and later generations.
Many countries support business start-ups to spur economic growth and reduce unemployment with different programmes. Evaluation studies of such programmes commonly rely on the conditional independence assumption (CIA), allowing a causal interpretation of the results only if all relevant variables affecting participation and success are accounted for. While the entrepreneurship literature has emphasised the important role of personality traits as predictors for start-up decisions and business success, these variables were neglected in evaluation studies so far due to data limitations. In this paper, we evaluate a new start-up subsidy for unemployed individuals in Germany using propensity score matching under the CIA. Having access to rich administrative-survey data allows us to incorporate usually unobserved personality measures in the evaluation and investigate their impact on the estimated effects. We find strong positive effects on labour market reintegration and earned income for the new programme. Most importantly, results including and excluding individuals׳ personalities do not differ significantly, implying that concerns about potential overestimation of programme effects in the absence of personality measures might be less justified if the set of other control variables is rich enough.
