A1 - van Knippenberg, Daan A1 - Kearney, Eric T1 - Paradoxical leadership as sensegiving BT - stimulating change-readiness and change-oriented performance JF - Leadership & organization development journal N2 - Purpose Paradoxical leadership (PL) is an emerging perspective to understand how leaders help followers deal with paradoxical demands. Recently, the positive relationship between PL and follower performance was established. This paper builds on and extends this research by interpreting PL as sensegiving and developing theory about mediation in the relationship between PL and adaptive and proactive performance. Design/methodology/approach The paper develops a new measure for PL as sensegiving and provides a test of the mediation model with data from two different sources and two measurement times in a German company. Findings Multilevel mediation analysis (N = 154) supports the mediation model. Originality/value The paper presents sensegiving about paradox as a core element of PL, which informs the choice of change-readiness as mediator. This study also develops and validates a scale to measure PL in future research.

BT - scenario analysis on buyer–seller negotiations JF - The journal of business & industrial marketing N2 - Purpose: This study aims to provide probable future developments in the form of holistic scenarios for business negotiations. In recent years, negotiation research did not put a lot of emphasis on external changes. Consequently, current challenges and trends are scarcely integrated, making it difficult to support negotiation practice perspectively. Design/methodology/approach: This paper applies the structured, multi-method approach of scenario analysis. To examine the future space of negotiations, this combines qualitative and quantitative measures to base our analysis on negotiation experts’ assessments, estimations and visions of the negotiation future. Findings: The results comprise an overview of five negotiation scenarios in the year 2030 and of their individual drivers. The five revealed scenarios are: digital intelligence, business as usual, powerful network – the route to collaboration, powerful network – the route to predominance and system crash. Originality/value: The scenario analysis is a suitable approach that enables to relate various factors of the negotiation environment to negotiations themselves and allows an examination of future changes in buyer–seller negotiations and the creation of possible future scenarios. The identified scenarios provide an orientation for business decisions in the field of negotiation.

JF - Industrial marketing management : the international journal for industrial and high-tech firms N2 - The number of alternative suppliers is widely considered to be the most important source of power in supply chains. It is common knowledge that a buying company benefits from an increasing number of suppliers until a marginalization effect occurs. Consequently, a cost-benefit optimum must exist but has not been analyzed in a sufficiently differentiated manner in the literature. Particularly, research has not taken the variety of product groups, which is reflected by the degree of innovation, into account. Using a two-way analysis of variance, this study identifies the cost-benefit optimum for the number of suppliers and analyzes the moderating role of the degree of innovation. The analysis is based on real automotive business-to-business negotiation data. The results reveal that a cost-benefit optimum is reached at a number of three suppliers at the most. Furthermore, the impact of the number of suppliers is higher for innovative products than for more functional products. Purchasing managers can use the findings to determine the optimal size of their supplier choice set.

Incumbents are particularly exposed to the field of tension between maintaining and renewing their business model. Banking is one of the industries most affected by digitalization, with a large stream of digital innovations around Fintech. Most research contributions focus on digital innovations, such as Fintech, but there are only a few studies on the related challenges and perspectives of incumbent organizations, such as traditional banks. Against this background, this dissertation examines the specific causes, effects and solutions for traditional banks in digital transformation − an underrepresented research area so far. The first part of the thesis examines how digitalization has changed the latent customer expectations in banking and studies the underlying technological drivers of evolving business-to-consumer (B2C) business models. Online consumer reviews are systematized to identify latent concepts of customer behavior and future decision paths as strategic digitalization effects. Furthermore, the service attribute preferences, the impact of influencing factors and the underlying customer segments are uncovered for checking accounts in a discrete choice experiment. The dissertation contributes here to customer behavior research in digital transformation, moving beyond the technology acceptance model. In addition, the dissertation systematizes value proposition types in the evolving discourse around smart products and services as key drivers of business models and market power in the platform economy. The second part of the thesis focuses on the effects of digital transformation on the strategy development of financial service providers, which are classified along with their firm performance levels. Standard types are derived based on fuzzy-set qualitative comparative analysis (fsQCA), with facade digitalization as one typical standard type for low performing incumbent banks that lack a holistic strategic response to digital transformation. Based on this, the contradictory impact of digitalization measures on key business figures is examined for German savings banks, confirming that the shift towards digital customer interaction was not accompanied by new revenue models diminishing bank profitability. The dissertation further contributes to the discourse on digitalized work designs and the consequences for job perceptions in banking customer advisory. The threefold impact of the IT support perceived in customer interaction on the job satisfaction of customer advisors is disentangled. In the third part of the dissertation, solutions are developed design-oriented for core action areas of digitalized business models, i.e., data and platforms. A consolidated taxonomy for data-driven business models and a future reference model for digital banking have been developed. The impact of the platform economy is demonstrated here using the example of the market entry by Bigtech. The role-based e3-value modeling is extended by meta-roles and role segments and linked to value co-creation mapping in VDML. In this way, the dissertation extends enterprise modeling research on platform ecosystems and value co-creation using the example of banking. N2 - Traditionelle Unternehmen sehen sich angesichts des zunehmend digitalen Kundenverhaltens und gesteigerten digitalen Wettbewerbs damit konfrontiert, ihr Geschäftsmodell adäquat für das digitale Zeitalter weiterzuentwickeln. Insbesondere etablierte Unternehmen befinden sich dabei in einem Spannungsfeld aus Bewahrung und Erneuerung. Der Großteil jüngerer Forschungsbeiträge zum Bankwesen fokussiert sich auf digitale Fintech-Innovationen, nur wenige Studien befassen sich mit Herausforderungen und Perspektiven traditioneller Banken. Vor diesem Hintergrund untersucht die Dissertation die Ursachen und Wirkungen der Digitalen Transformation im Bankwesen und zeigt Lösungswege für traditionelle Banken auf. Der erste Teil der Dissertation untersucht die Ursachen der Digitalen Transformation im Banking. Neuartige Einflussfaktoren und Entscheidungspfade im Kundenverhalten werden als strategische Digitalisierungstreiber für Banken identifiziert. Darauf aufbauend werden in einem Discrete-Choice-Experiment die Präferenzen deutscher Bankkunden hinsichtlich digitaler und nicht-digitaler Dienstleistungsattribute am Beispiel von Girokonten untersucht. Die Arbeit leistet einen über das Technologieakzeptanzmodell hinausgehenden Beitrag zur Erforschung des Kundenverhaltens in der Digitalen Transformation. Ein weiterer Forschungsbeitrag systematisiert anschließend wesentliche Charakteristika smarter Produkte und Dienstleistungen als Treiber von Geschäftsmodellen und Marktmacht in der Plattformökonomie. Der zweite Teil der Arbeit befasst sich zunächst mit den Auswirkungen der Digitalen Transformation auf die Strategieentwicklung von traditionellen Finanzdienstleistern, die mittels Fallstudien entlang ihres Finanzerfolgs typologisiert werden. Die Fassadendigitalisierung wird als Standardtyp traditioneller Anbieter systematisiert, die zwar zunehmend auf digitale Kundeninteraktion setzen, aber die Geschäftsmodelldimension der Digitalen Transformation vernachlässigen. Darauf aufbauend werden in Panelregressionsanalysen die Auswirkungen der Digitalisierung auf deutsche Sparkassen auf betriebswirtschaftliche Kennzahlen untersucht. Eine weitere quantitative Studie untersucht die Wirkungen neuartiger IT-Beratungswerkzeuge auf die Arbeitszufriedenheit von Bankkundenberatern. Die Dissertation leistet hiermit einen Beitrag zur Transformationsforschung in den Bereichen Bankstrategie und Arbeitsprozesse. Im dritten Teil der Dissertation werden gestaltungsorientiert Lösungsartefakte für die zentralen Handlungsfelder digitalisierter Geschäftsmodelle - Daten und Plattformen - entwickelt. Dies schließt einerseits eine konsolidierte Taxonomie für datengetriebene Geschäftsmodelle und andererseits ein Referenzmodell für zukünftige plattformbasierte Bankenökosysteme ein. Die rollenbasierte Referenzmodellierungsmethodik e3-value wird um Meta-Rollen und Rollensegmente erweitert, um die die strategischen Auswirkungen plattformbasierter Geschäftsmodelle aufzuzeigen. Hiermit erweitert die Dissertation die Unternehmensmodellierungsforschung im Bereich digitaler Plattform-Ökosysteme am Beispiel des Bankwesens.

The effects of blockchain on the relationship of public administrations with external stakeholders T1 - Auf dem Weg zu gemeinsam erbrachten Verwaltungsleistungen? Die Auswirkungen von Blockchain auf die Beziehungen zwischen öffentlichen Verwaltungen und externen Akteuren N2 - Public administrations confront fundamental challenges, including globalization, digitalization, and an eroding level of trust from society. By developing joint public service delivery with other stakeholders, public administrations can respond to these challenges. This increases the importance of inter-organizational governance—a development often referred to as New Public Governance, which to date has not been realized because public administrations focus on intra-organizational practices and follow the traditional “governmental chain.” E-government initiatives, which can lead to high levels of interconnected public services, are currently perceived as insufficient to meet this goal. They are not designed holistically and merely affect the interactions of public and non-public stakeholders. A fundamental shift toward a joint public service delivery would require scrutiny of established processes, roles, and interactions between stakeholders. Various scientists and practitioners within the public sector assume that the use of blockchain institutional technology could fundamentally change the relationship between public and non-public stakeholders. At first glance, inter-organizational, joint public service delivery could benefit from the use of blockchain. This dissertation aims to shed light on this widespread assumption. Hence, the objective of this dissertation is to substantiate the effect of blockchain on the relationship between public administrations and non-public stakeholders. This objective is pursued by defining three major areas of interest. First, this dissertation strives to answer the question of whether or not blockchain is suited to enable New Public Governance and to identify instances where blockchain may not be the proper solution. The second area aims to understand empirically the status quo of existing blockchain implementations in the public sector and whether they comply with the major theoretical conclusions. The third area investigates the changing role of public administrations, as the blockchain ecosystem can significantly increase the number of stakeholders. Corresponding research is conducted to provide insights into these areas, for example, combining theoretical concepts with empirical actualities, conducting interviews with subject matter experts and key stakeholders of leading blockchain implementations, and performing a comprehensive stakeholder analysis, followed by visualization of its results. The results of this dissertation demonstrate that blockchain can support New Public Governance in many ways while having a minor impact on certain aspects (e.g., decentralized control), which account for this public service paradigm. Furthermore, the existing projects indicate changes to relationships between public administrations and non-public stakeholders, although not necessarily the fundamental shift proposed by New Public Governance. Lastly, the results suggest that power relations are shifting, including the decreasing influence of public administrations within the blockchain ecosystem. The results raise questions about the governance models and regulations required to support mature solutions and the further diffusion of blockchain for public service delivery. N2 - Öffentliche Verwaltungen stehen vor grundlegenden Herausforderungen, darunter Globalisierung, Digitalisierung und ein schwindendes Vertrauen der Gesellschaft. Durch die gemeinsame Erbringung von Verwaltungsleistungen mit anderen Akteuren können öffentliche Verwaltungen auf diese Herausforderungen reagieren. Dies erhöht die Bedeutung der interorganisatorischen Governance – eine Entwicklung, die oft als New Public Governance bezeichnet wird und die bisher nicht realisiert wurde, weil sich die öffentlichen Verwaltungen auf organisationsinterne Praktiken konzentrieren und der traditionellen "Governmental chain" folgen. E-Government-Initiativen, die zu einem hohen Maß an vernetzten Verwaltungsleistungen führen können, werden derzeit als unzureichend angesehen, um dieses Ziel zu erreichen. Sie sind nicht ganzheitlich konzipiert und betreffen lediglich die Interaktionen zwischen öffentlichen und nicht-öffentlichen Akteuren. Ein grundlegender Wandel hin zu einer gemeinsamen Erbringung von Verwaltungsleistungen würde eine Überprüfung der etablierten Prozesse, Rollen und Interaktionen zwischen den Beteiligten erfordern. Verschiedene Wissenschaftler und Praktiker im öffentlichen Sektor gehen davon aus, dass der Einsatz der institutionellen Blockchain-Technologie die Beziehungen zwischen öffentlichen und nicht-öffentlichen Akteuren grundlegend verändern könnte. Auf den ersten Blick könnte die interorganisationale, gemeinsame Erbringung von Verwaltungsleistungen von der Nutzung der Blockchain profitieren. Diese Dissertation soll diese weit verbreitete Annahme beleuchten. Ziel dieser Arbeit ist es daher, die Auswirkungen von Blockchain auf die Beziehungen zwischen öffentlichen Verwaltungen und nicht-öffentlichen Akteuren zu belegen. Dieses Ziel wird durch die Definition von drei wesentlichen Erkenntnisbereichen verfolgt. Erstens soll in dieser Dissertation die Frage beantwortet werden, ob Blockchain geeignet ist, um New Public Governance zu ermöglichen, und es sollen Fälle ermittelt werden, in denen Blockchain möglicherweise nicht die richtige Lösung ist. Der zweite Bereich zielt darauf ab, den Status quo der bestehenden Blockchain-Implementierungen im öffentlichen Sektor empirisch zu verstehen und zu prüfen, ob sie den wichtigsten theoretischen Schlussfolgerungen entsprechen. Der dritte Bereich untersucht die sich verändernde Rolle der öffentlichen Verwaltungen, da das Blockchain-Ökosystem die Zahl der Beteiligten erheblich erhöhen kann. Entsprechende Forschungsarbeiten werden durchgeführt, um Einblicke in diese Bereiche zu gewinnen, z. B. durch die Kombination von theoretischen Konzepten mit empirischen Befunden, die Durchführung von Interviews mit Fachleuten und wichtigen Akteuren führender Blockchain-Implementierungen und die Durchführung einer umfassenden Stakeholder-Analyse mit anschließender Visualisierung der Ergebnisse. Die Ergebnisse dieser Dissertation zeigen, dass Blockchain New Public Governance in vielerlei Hinsicht unterstützen kann, während sie sich auf bestimmte Aspekte (z. B. dezentrale Steuerung), die dieses Verwaltungsparadigma ausmachen, nur wenig auswirkt. Darüber hinaus deuten die bestehenden Projekte auf Veränderungen in den Beziehungen zwischen öffentlichen Verwaltungen und nicht-öffentlichen Akteuren hin, wenn auch nicht unbedingt auf die von der New Public Governance vorgeschlagene grundlegende Veränderung. Schließlich deuten die Ergebnisse darauf hin, dass sich die Machtverhältnisse verschieben, einschließlich des abnehmenden Einflusses der öffentlichen Verwaltungen innerhalb des Blockchain-Ökosystems. Die Ergebnisse werfen Fragen zu den Governance-Modellen und zur Regulierung auf, die zur Unterstützung ausgereifter Lösungen und der weiteren Verbreitung von Blockchain für die Erbringung öffentlicher Verwaltungsleistungen erforderlich sind.

P. T1 - Priming creativity: Doing math reduces creativity and happiness whereas playing short online games enhance them JF - Frontiers in Education N2 - Creative thinking is an indispensable cognitive skill that is becoming increasingly important. In the present research, we tested the impact of games on creativity and emotions in a between-subject online experiment with four conditions (N = 658). (1) participants played a simple puzzle game that allowed many solutions (priming divergent thinking); (2) participants played a short game that required one fitting solution (priming convergent thinking); (3) participants performed mental arithmetic; (4) passive control condition. Results show that divergent and convergent creativity were higher after playing games and lower after mental arithmetic. Positive emotions did not function as a mediator, even though they were also heightened after playing the games and lower after mental arithmetic. However, contrary to previous research, we found no direct effect of emotions, creative self-efficacy, and growth- vs. fixed on creative performance. We discuss practical implications for digital learning and application settings.

We argue that firms are more likely to disclose VB performance measures when information asymmetry is greater, as greater information asymmetry means firms have a greater need to credibly signal a shareholder value orientation. Using a hand-collected dataset of German listed firms covering 1,528 firm-years from 2004 to 2011, we demonstrate that firms are more likely to disclose a VB performance measure if the free float is larger than the blocking minority and also, when firms are large, if they have high foreign sales to total sales ratios and are not cross-listed internationally. Our results indicate that German firms use VB performance measures to improve investor communication and to substantiate their shareholder value orientation. Our results should be interpreted against a background of increased shareholder value orientation and sophisticated cost accounting in German firms.

Objective This study aims to identify which barrier factors impede the usage of wearables for assessing individual risk scores for health insurances, despite its technological feasibility, and to rank these barriers according to their relevance. Methods To reach these goals, we conduct a ranking-type Delphi study with the following three stages. First, we collected possible barrier factors from a panel of 16 experts and consolidated them to a list of 11 barrier categories. Second, the panel was asked to rank them regarding their relevance. Third, to enhance the panel consensus, the ranking was revealed to the experts, who were then asked to re-rank the barriers. Results The results suggest that regulation is the most important barrier. Other relevant barriers are false or inaccurate measurements and application errors caused by the users. Additionally, insurers could lack the required technological competence to use the wearable data appropriately. Conclusion A wider use of wearables and health apps could be achieved through regulatory modifications, especially regarding privacy issues. Even after assuring stricter regulations, users’ privacy concerns could partly remain, if the data exchange between wearables manufacturers, health app providers, and health insurers does not become more transparent.

Mechanisms by which data is generated, shared, and ultimately lead to policy responses are crucial for enhancing transparency and legitimacy of decisions. At the same time, the volume, complexity and volatility of data are growing. Against this background, mechanisms, actors, and problems of data-driven scientific policy advice are analysed. The study reveals role conflicts, ambiguities, and tensions in the interaction between scientific advisors and policy-makers.

We construct a novel panel dataset combining data on regional GDP and power capacity additions for different technologies between 1960 and 2015, which covers 65% of the global power capacity that has been installed in this period. We use an event study design to identify the effect of power capacity addition on GDP per capita, exploiting the fact that the exact amount of power capacity coming online each year is determined by random construction delays. We find evidence that GDP per capita increases by 0.2% in the 6 years around the coming online of 100 MW coal-fired power capacity. We find similar effects for hydropower capacity, but not for any other type of power capacity. The positive effects are regionally bounded and stronger for projects on new sites (green-field). The magnitude of this effect might not be comparable to the total external costs of building new coal-fired power capacity, yet our results help to explain why policymakers favor coal investments for spurring regional growth.

Based on algorithms, big data analysis, machine learning, and other technologies, these services minimize the necessity for human intervention. Based on an international three-stage Delphi study, we provide a plausible forecast of the development of the robo advisor industry, with regards to market development, competition, drivers of growth, customer segments, challenges, services, technologies, and societal change. The results suggest that the financial advice market will experience a further increase in the number of robo advisor services available. Existing and traditional financial advice players will be forced to adjust to the changing environment of the market. Due to low fees and ease of use, robo advisors will be made available to a broad cross section of society, and will cause significant market losses for traditional investment advice companies. Ten years from now, the predominant investment class will remain Exchange Traded Funds (ETFs). Even though degrees of human intervention are expected to vary considering the complexity of advice, automation will increase in significance when it comes to the development of robo advisors.

Environmental, social, and governance (ESG) issues are therefore gaining increasing importance, in line with the growing demand for corporate sustainability. ESG ratings foster the comparison of companies with respect to their sustainable practices. This study aims to investigate how ESG ratings impact financial performance in the European food industry. Ordinary least squares regression is applied to analyze the relation between ESG ratings and financial performance over a 4-year period from 2017 to 2020. The profitability measures Return on Assets (ROA) and Return on Equity (ROE) are employed as financial performance measures, while ESG ratings are obtained from the database CSRHub. Results show that higher ESG ratings are associated with better financial performance. Although the effect is modest in the present study, the findings support previous results that ESG ratings are positively related to financial performance. Nonetheless, they also highlight that ESG ratings strongly converge to the mean, which depicts the need to reassess whether ESG ratings are able to measure actual ESG behavior.

A1 - Tiberius, Victor T1 - Dyadic business model convergence or divergence in alliances? BT - a configurational approach JF - Journal of business research N2 - In this study, we contribute to the scholarly conversation on firm-level business model changes following a neoconfigurational approach. By exploring configurations of business model changes over time, we add the direction of business model changes-namely business model convergence or divergence-as a vital avenue to the business model innovation literature. We identify necessary business model convergence and divergence recipes in a sample of N = 217 strategic dyadic alliances. Firstly, technological proximity emerges as a single precondition to both converging and diverging business models. Secondly, business models between competitors either converge through complementarities or tend not to change relative to each other. Thirdly, equity participation enables business model divergence through co-specialization. We conclude with a discussion of business model trajectories and future research directions.
