Blockchain Value Creation Logics and Financial Returns

With its complexities and portfolio-nature, the advent of blockchain technology presents several use cases to stakeholders for business value appropriation and financial gains. This 3-essay dissertation focuses on three exemplars and research approaches to understanding the value creation logics of blockchain technology for financial gains. The first essay is a conceptual piece that explores five main affordances of blockchain technology and how these can be actualized and assimilated for business value. Based on the analysis of literature findings, an Affordance-Experimentation-Actualization-Assimilation (AEAA) model is proposed. The model suggests five affordance-to-assimilation value chains and eight value interdependencies that firms can leverage to optimize their value creation and capture during blockchain technology implementation. The second essay empirically examines the financial returns of public firms\u27 blockchain adoption investments at the level of the three main blockchain archetypes (private-permissioned, public-permissioned and permissionless. Drawing upon Fichman\u27s model of the option value of innovative IT platform investments, the study examines business value creation through firm blockchain strategy (i.e., archetype instances, decentralization, and complementarity), learning (i.e., blockchain patents and event participation), and bandwagon effects using quarterly data of firm archetype investments from 2015 to 2020. The study\u27s propensity score matching utilization and fixed-effects modeling provide objective quantification of how blockchain adoption leads to increases in firm value (performance measured by Tobin\u27s q) at the archetype level (permissionless, public permissioned, and private permissioned). Surprisingly, a more decentralized archetype and a second different archetype implementation are associated with a lower Tobin\u27s q. In addition, IT-option proxy parameters such as blockchain patent originality, participation in blockchain events, and network externality positively impact firm performance, whereas the effect of blockchain patents is negative. As the foremost and more established use case of blockchain technology whose business value is accessed in either of the five affordances and exemplifies a permissionless archetype for financial gains, bitcoin cryptocurrency behavior is studied through the lens of opinion leaders on Twitter. The third essay this relationship understands the hourly price returns and volatility shocks that sentiments from opinion leaders generate and vice-versa. With a dynamic opinion leader identification strategy, lexicon and rule-based sentiment analytics, I extract sentiments of the top ten per cent bitcoin opinion leaders\u27 tweets. Controlling for various economic indices and contextual factors, the study estimates a vector autoregression model (VAR) and finds that finds that Bitcoin return granger cause Polarity but the influence of sentiment subjectivity is marginal and only stronger on bitcoin price volatility. Several key implications for blockchain practitioners and financial stakeholders and suggestions for future research are discussed

Exploring Blockchain Governance

Blockchain systems continue to attract significant interest from both practitioners and researchers. What is more, blockchain systems come in various types, such as cryptocurrencies or as inter-organizational systems in business networks. As an example of a cryptocurrency, Bitcoin, one of the most prominent blockchain systems to date and born at the time of a major financial crisis, spearheaded the promise of relying on code and computation instead of a central governing entity. Proponents would argue that Bitcoin stood the test of time, as Bitcoin continues to operate to date for over a decade. However, these proponents overlook the never-ending, heated debates “behind the scenes” caused by diverging goals of central actors, which led to numerous alternative systems (forks) of Bitcoin. To accommodate these actors’ interests in the pursuit of their common goal is a tightrope act, and this is where this dissertation commences: blockchain governance. Based on the empirical examples of various types and application domains of blockchain systems, it is the goal of this dissertation to 1) uncover governance patterns by showing, how blockchain systems are governed, 2) derive governance challenges faced or caused by blockchain systems, and, consequently, to 3) contribute to a better understanding to what blockchain governance is. This dissertation includes four parts, each of these covering different thematical areas: In the first part, this dissertation focuses on obtaining a better understanding of blockchain governance’s context of reference by studying blockchain systems from various application domains and system types, for example, led by inter-organizational networks, states, or an independent group of actors. The second part, then, focuses on a blockchain as an inter-organizational system called “cardossier”, a project I was involved in, and its governance as a frame of reference. Hereupon, for one, I report on learnings from my project involvement in the form of managerial guidelines, and, for two, I report on structural problems within cardossier, and problems caused by membership growth and how they can be resolved. The third part focuses on a wider study of blockchains as inter-organizational systems, where I summarize findings of an analysis of 19 blockchain consortia. The findings, for one, answer the question of why blockchain consortia adopt blockchain technology, and, for two, show internal and external challenges these systems faced to derive managerial recommendations. The fourth and last part studies blockchain governance’s evolution and contributes an analysis of blockchain’s governance features and its contrast to established modes of governance. These four parts, altogether, have scientific value as they increase our understanding on blockchain governance. Consequently, this dissertation contributes to the body of knowledge on modes of governance, distributed system governance, and blockchain governance in general. I do so, by grounding the concept of blockchain governance in empirical detail, showing how these systems are governed on various application domains and system types, and by studying empirical challenges faced or caused by these systems. This approach is relevant and necessary, as blockchain systems in general, but particularly outside of cryptocurrencies, mostly still are in pursuit of a sustainable blockchain governance. As blockchains can be expected to continue to mature, the upcoming years offer very fruitful ground for empirical research along the empirical insights and theoretical lines shown in this dissertation

The development of IT identity due to social media use : antecedents and impact on computer-based office work during COVID-19 pandemic

IT identity is a relatively new concept in the area of Management Information Systems (MIS). Its importance has become increasingly pronounced as identity is one of the predictors of human behavior. At the same time, understanding the behavior of individuals when using information technology (IT) in the workplace represents the link between technology investments and increased performance through IT. In this respect, one of the most used communication technologies recently, social media, allows individuals to extensively experience different facets of their identities. The overall objective of this thesis is to understand the development of IT identity due to social media use and assess its impact on computer-based office work during the COVID-19 pandemic. Three specific objectives were defined for this purpose. Thus, the thesis is structured in three papers that sought to respond to each of the specific objectives, which are: (i) identify the possible antecedents of the development of IT identity due to social media use, (ii) the connection between them and the three reflective dimensions that constitute the identity of IT and, finally, (iii) the impact of IT identity due to the use of social media in the organizational scope. The first paper is a theoretical study and proposes the adaptation and expansion of Carter's original theoretical model (2012) from the theoretical instances related to this technology and that can influence the development of IT identity due to social media use. As a result, a conceptual model was developed. Ten propositions related to the concepts derived from the literature and inserted in three main instances of IT identity development were presented due to the use of social media. The empirical investigation of the relationship between the antecedents of the model proposed in the first paper and the three dimensions of IT identity began in the second article of the thesis. For this purpose, a netnography was proposed and executed between 2019 and 2021. One of the paper's findings indicated that the frequency of use of WhatsApp can lead to precipitation of the most strongly polarized behavior and that one of the reflective dimensions of IT identity, relatedness with WhatsApp, can play a preponderant role in the precipitation of such behavior. From this result, in paper 3, a quantitative and exploratory study, based on duality theory, sought to develop and test hypotheses about how IT identity concerning social media can benefit, but at the same time bring negative consequences for computer-based office workers in the current period of the COVID-19 pandemic. For this, a model was proposed showing the relationship between the dimensions of IT identity and four facets of the so-called New Ways of Working. Among the study's findings, it was verified that IT identity in relation to social media platforms could be a positive factor in preserving the cohesion of employees professional identity since feelings of affinity and emotional energy in relation to these technologies favored access to organizational knowledge and colleagues when working remotely. This thesis can contribute to expanding Carter's (2012) model to contemplate a class of IT as social media is constituted (paper 1). In turn, the expansion of the original model can potentially contribute to broadening the understanding of this technology's role in fostering polarized behavior in the use of WhatsApp, one of the most used social media these times(paper 2). Finally, in the third paper, the indication that the frequency of WhatsApp use may be associated with a strong IT identity about this technology (verified in paper 2) led to the proposition of a model to empirically test how the three dimensions of IT Identity in relation to the use of social media, directly and indirectly, influence the aspects of new ways of working for workers using computer devices to perform their duties. Emotional energy in relation to social media (i.e., prolonged feelings of confidence, enthusiasm, and energy toward social media) is positively related to superior performance when individuals direct it to their work use, allowing them to better handle the work-life conflict. The thesis presents limitations regarding its ability to inferences that were addressed in each of the papers. Similarly, suggestions for future research were presented in each paper. Finally, the conclusion chapter presents the integration of the thesis papers to form the complete study, the overview of research objectives, the main results, contributions to academia and practice, its limitations, and suggestions for future research.A identidade de TI é um conceito relativamente novo na área de Gestão de Sistemas de Informação (GSI). A sua importância tem se tornado cada vez mais acentuada na medida que a identidade é um dos preditores do comportamento humano. Paralelamente, a compreensão do comportamento dos indivíduos ao utilizar a tecnologia da informação (TI) no ambiente de trabalho representa o elo entre os investimentos em tecnologia e o aumento do desempenho por meio da TI. Sob esse aspecto, uma das tecnologias de comunicação mais usadas em tempos atuais, as mídias sociais, permitem de forma extensiva que os indivíduos experimentem diferentes facetas das suas identidades. O objetivo geral dessa tese é compreender o desenvolvimento da identidade de TI devido ao uso de mídias sociais e avaliar o seu impacto para os trabalhadores de escritório que utilizam dispositivos computacionais para executar suas funções de trabalho durante o período da pandemia de COVID-19. Para isso foram definidos três objetivos específicos. Sendo assim, a tese está estruturada em três artigos que buscam responder a cada um dos objetivos específicos, quais são: (i) identificar os possíveis antecedentes do desenvolvimento da identidade de TI devido ao uso de mídias sociais, (ii) a conexão entre eles e as três dimensões reflexivas que constituem a identidade de TI e, por fim, (iii) o impacto da identidade de TI devido ao uso de mídias sociais no âmbito organizacional. O primeiro artigo, de natureza teórica, propõe a adaptação e expansão do modelo teórico original de Carter (2012) a partir das instâncias teóricas aderentes ao uso e que influenciam o desenvolvimento da identidade de TI pelo uso de mídias sociais. Como resultado, foi desenvolvido um modelo conceitual em que foram apresentadas dez proposições interrelacionando os conceitos derivados da literatura e inseridos em três instâncias principais de desenvolvimento da identidade de TI devido ao uso de mídias sociais. A investigação empírica da relação entre os antecedentes do modelo proposto no artigo 1 e as três dimensões da identidade de TI iniciou-se na sequência no segundo artigo da tese. Para isso foi proposta uma netnografia que foi executada entre 2019 e 2021. Um dos achados do artigo indicou que a frequência de uso do WhatsApp pode levar a precipitação do comportamento mais fortemente polarizado e que uma das dimensões reflexivas da identidade de TI, a afinidade com o WhatsApp, pode desempenhar um papel preponderante na precipitação de tal comportamento. A partir desse resultado, no artigo 3, de natureza quantitativa e exploratória, tendo como base a teoria da dualidade, buscou-se desenvolver e testar hipóteses sobre como a identidade de TI em relação às mídias sociais pode beneficiar, mas ao mesmo tempo trazer consequências negativas para os trabalhadores de escritório que usam principalmente dispositivos computacionais para cumprir suas tarefas no atual período da pandemia de COVID-19. Para isso, foi proposto um modelo apresentando a relação entre as dimensões da identidade de TI e quatro facetas das chamadas Novas Formas de Trabalho. Entre os achados deste estudo, foi verificado que a identidade de TI em relação às plataformas de mídias sociais pode ser um fator positivo na preservação da coesão da identidade profissional dos colaboradores, uma vez que sentimentos de afinidade e energia emocional em relação a essas tecnologias favoreceram o acesso ao conhecimento organizacional e aos colegas ao trabalhar remotamente. Destacam-se como contribuições dessa tese a expansão do modelo de Carter (2012) para contemplar uma classe de TIs como são constituídas as mídias sociais (artigo 1). Por sua vez, a expansão do modelo original contribuiu para ampliar a compreensão do papel dessa tecnologia em fomentar o comportamento polarizado no uso do WhatsApp, uma das mídias sociais mais utilizadas em tempos atuais (artigo 2). Finalmente, no terceiro artigo a indicação de que a frequência de uso no WhatsApp pode estar associada a uma forte identidade de TI em relação a essa tecnologia (verificada no artigo 2), levou a proposição de um modelo para testar empiricamente de que forma as três dimensões da IT Identity em relação ao uso de mídias sociais influenciam direta e indiretamente os aspectos das novas formas de trabalho para os trabalhadores que utilizam dispositivos computacionais para desempenhar suas funções. A energia emocional em relação às mídias sociais (ou seja, sentimentos prolongados de confiança, entusiasmo e energia em relação às mídias sociais) está positivamente relacionada a um desempenho superior quando os indivíduos a direcionam para o seu uso do trabalho, permitindo-lhes também lidar melhor com os conflitos entre a vida profissional e a vida profissional. A tese apresenta limitações quanto a sua capacidade de inferências que foram endereçadas em cada um dos artigos. Da mesma forma, sugestões de pesquisas futuras foram apresentadas em cada artigo. Por fim, o capítulo de conclusão apresenta a integração dos artigos da tese para a formação do estudo completa, a retomada dos objetivos de pesquisa, os principais resultados, contribuições para a academia e para a prática, suas limitações e sugestões para pesquisas futuras

ICT-driven interactions: on the dynamics of mediated control

Interactions driven by Information Communications Technologies (ICT) have gained significant acceptance and momentum in contemporary organisational settings, this is illustrated by their massive adoption and varied deployment across the various levels of an organisation’s hierarchy. ICTs such as mobile telephones, Personal Digital Assistants (PDA), videoconferencing, BlackBerries and other forms of portable and immovable computing technologies provide enduring bases for mediated interactions in human activities. This thesis looks into the dynamics of ICT-driven interactions and, distinctively, focuses on the manifestations and implications of mediated control in a collaborative environment. The study draws on the concept of administrative behaviour which leads to the observation that the nature of mediated control is not static, but evolutionarily dynamic that springs from highly unpredictable contexts of work. Thus, interactions driven by ICTs influence and change the dynamics of mediated control against the background of the rhythm, structure and direction of an organisation’s purposeful undertakings. Findings indicate, quite paradoxically, that networks set up through the instrumentality of technology mediated interaction discourage domination and inspire individual discretion in spite of their promise of electronic chains. The analysis reflects the notion that mediated control is not only about the predetermination of targets that are attained at the subordinate level. Indeed, the study advocates a fundamental conceptualisation of mediated control as double-sided concept, integrating the use of discretion that, occasionally, makes subordinates drive and initiate key control techniques that steer organisational life. Therefore, through the application of philosophical hermeneutics for a rigorous data interpretation, this study develops an innovative and holistic understanding of mediated control which not only adds to, but also extends, the current organisational perception of control by the incorporation of discretion and, in the process, makes a distinctive contribution to scholarship

Modeling a systems-based framework for effective IT auditing and assurance for less regulatory environments

Information Technology (IT) has become indispensable in contemporary business processes and in business value creation strategies. Those charged with governance, risk management and compliance are, often, challenged by sophisticated IT oriented decision-making dilemmas due to complex IT use in contemporary business processes. Investors and other stakeholders increasingly expect very rich, reliable and transparent assurance that their interests are safe. Auditors, as a result, are looked upon to expand their role to leverage the functions of those charged with governance and management. IT audit literature, hence, demonstrates existence of several best practices aimed at meeting the increasing demand for more audit and assurance outcomes that bridge the widening audit expectations gaps. In developing countries with less stringent regulatory systems, however, attempts to implement many of these frameworks have proved unsuccessful. Reasons include paucity of guidance in the frameworks and lack of suitable theoretical foundations to resort to for solutions to implementation challenges. Extant literature review reveals scanty research effort by practitioners or academicians in the field in the empirical situation to design a more suitable framework to serve as intervention. In this research an attempt has been made to create an intervention by designing a framework, i.e. an artefact for IT auditing for less regulated business environments. By adductive inference the cybernetics theory of viable systems approach was ingrained as the theoretical foundation from which the variables for the design were extracted. The abduction was based on the diagnostic power and ability to support self-regulation in a less regulatory environment. Action design research (ADR) approach was employed to achieve the research objective. Both qualitative and quantitative techniques were found to be useful for the evaluation and data analysis. At the design phase, a multiple case study method together with workshops were employed to gain insight into the problem and to collect data to support the design process. Four organisations from both public and private sectors in Ghana were selected to participate in the research. At the evaluation stage a survey technique was used to collect data mainly for the validation of construct variables and the refinement of the framework. The questionnaire scale used was 1=Strongly Disagree; 2=Disagree; 3=Somewhat Agree; 4=Agree and 5=Strongly Agree. A total of 136 respondents who included IT audit and Internal audit practitioners, Audit trainees and students, Directors and management staff were involved from four selected organisations. A factor analysis yielded twenty variables extracted from the ingrained theory for the building of a conceptual model which were grouped into six factors or domains. The entire conceptual model was tested with PLS-SEM technique because of the causal relationships that motivated the development of the conceptual hypotheses. A composite reliability used to assess the internal consistency of the model was overall adequate with values greater than 0.7. Similarly, a convergent validity of the model showed that all the variables were above the threshold value of 0.5. Thus, the model and design theory were found to be reliable and valid. Correlation and regression analysis was applied in testing individual hypotheses and the results helped to reorganise the final framework. The study contributed an artefact in the field of IT audit which represents a comprehensive teachable practitioner’s guide for the improvement of the IT audit practice. The framework also serves as guidance to those charged with governance and management in monitoring, self-review and as framework to attain IT audit readiness in less regulatory environments. Implementation challenges are expected to be resolved by reverting to the ingrained theory

Generative Mechanisms for Digital Platform Ecosystem Evolution

Despite their growing economic importance and rapid proliferation across various industries, successful digital platform ecosystems remain difficult to build and sustain over time. Facing challenges stemming from the turbulent and uncertain environment, in which they operate, and from the accumulated over time internal inefficiencies, digital platform ecosystems need to evolve and adapt rapidly. Despite the importance of understanding how and why this evolutionary process occurs, research on this topic has remained elusive. Building upon the notion of generative mechanisms, this PhD dissertation seeks to unravel the various mechanisms, which contingently shape the evolution of digital platform ecosystems. To this end, this research investigates the evolutionary process from three theoretical perspectives – Punctuated Equilibrium, Dialectical and Teleological, and by adopting multi-method approach. As a result, the PhD dissertation puts forward three process theories, each characterized by distinctive generative mechanisms, which collectively provide in-depth insights how digital platform ecosystems evolve over time in response to internal and external challenges

Institutionalisation of technology-supported organisational processes: A structurational perspective on IT service management support technology.

Increasing emphasis on strategic and operational IT-business alignment and best-practice frameworks (e.g. ITIL) has promoted the deployment of cross-functional process-based IT Service Management (ITSM) technologies within a wide range of organisations. Such technologies underpin core IT support processes such as Incident, Problem, and Change Management within a Service Management framework, promoting greater visibility and evaluation of IT contribution to the business. However, strategic and operational improvement of cross-functional ITSM processes requires effective embedding of process-supporting software in the organisation's ITSM process infrastructure. This research is based on an in-depth interpretive case-study of the use made of an ITSM software package in an IT Services department of a major UK university. In particular, this thesis examines the roles of organisational context, specific software functionality and design features, and organisational process infrastructure to develop an understanding of how particular ways of working with the software are embedded in various organisational routines. This research identifies a number of prevalent IT support working practices as organisational routines, and analyses the interrelationship between the working practices, organisational processes, the ITSM software artefact, and the immediate and wider organisational context. This thesis makes a number of contributions, including developing a theoretical framework for studying the role of technological artefact and organisational context and processes from the perspective of organisational routines and structuration theory
