This dissertation is an inquiry into the concept of value creation, motivated by a need for orientation in our demanding times. Based on the idea that true value only arises out of human (inter)subjective evaluations, we apply a psychological perspective on individual and collective value creation, thereby investigating a micro-foundation of value, as well as its application and operationalization. The dissertation is a cumulative dissertation that begins with an introductory chapter followed by four independent, yet connected studies. In Study 1, we develop a conceptual foundation for all other studies that involves a micro-foundation of value and value awareness as the competency to recognize fundamental evaluation categories as relevant. In Study 2, we conceptually delineate organizational public value and organizational reputation, two concepts of strategic relevance to organizations, that share similarities, but differ in fundamental dimensions. In Study 3 we operationalize value awareness through a practice-oriented instrument that helps individuals reflect, understand and develop their value awareness. In Study 4, we empirically investigate the link of an organization’s corporate social responsibility and work addiction via work meaningfulness and organizational identification, as well as value awareness. The studies are diverse and have multiple implications for research and practice. Overall, we suggest that individuals and collective entities should develop and operationalize their consideration of value creation on the level of (inter)subjective human experience. To realize actual value creation, many additional factors are important, but more value awareness could play a central role in increasing the chances of finding and creating more value for ourselves, others, and society as a whole.:INTRODUCTION Abstract Motivation and Purpose Theoretical Basis Research Objectives and Studies Excursion: The Leipzig Leadership Model Discussion of Findings Implications for Research Implications for Practice Conclusion References STUDY 1: MORE VALUE AWARENESS FOR MORE (PUBLIC) VALUE: RECOGNIZING HOW AND FOR WHOM VALUE IS TRULY CREATED 68 Abstract STUDY 2: SAME SAME BUT DIFFERENT: THE RELATIONSHIP BETWEEN ORGANIZATIONAL REPUTATION AND ORGANIZATIONAL PUBLIC VALUE Abstract Introduction Organizational Public Value and Organizational Reputation Comparing Public Value and Reputation Implications Conclusion References STUDY 3: THE VALUE AWARENESS PROFILE AS A NEW INSTRUMENT FOR INCREASING INDIVIDUAL VALUE AWARENESS: FOUNDATIONS AND FIRST EXPERIENCES Zusammenfassung Einleitung Theoretische Grundlagen: Wertschöpfung und Wertbewusstsein Wertbewusstsein messen und schaffen: Das Value Awareness Profile Evaluierung des Instruments auf Basis erster Anwendungserfahrungen Ergebnisdarstellung, Typifikation und Hypothesen Diskussion Fazit Literaturverzeichnis STUDY 4: TOO MUCH OF A GOOD THING?

This dissertation offers an integrative perspective on the interrelation of individual purpose, public value, and organizations in society. The cumulative dissertation comprises six independently published papers that differ in terms of methodology, research context, objectives, and contribution. The first study is based on the notion that an organization’s value depends on its contributions to the common good, as perceived by the public. The purpose of this study is to provide a corporate reporting approach that incorporates societal perspectives and, thus, advances (non-)financial reporting. The second study takes an explorative approach to investigate the individual-level characteristics of people who participate in the sharing economy as users and as providers. Study 3 examines the role of age as a determinant of individuals’ entrepreneurial behavior. Building on lifespan psychology and institutional theory, it argues for a U-shaped relationship between entrepreneurs’ age and their choice to create social value for their communities and societies. Study 4 enlarges the debate on the multifaceted consequences of Corporate Social Responsibility (CSR) by discussing the relationship between organizational CSR engagement and employee work addiction, shedding light on the potential risks associated with CSR. Study 5 is a case study and deals with the German family-equity company Haniel and depicts the process of implementing a Corporate Responsibility strategy throughout a holding company and its divisions. Study 6 provides an overview of public value research conducted by Moore, Bozeman, and Meynhardt and shows how public managers can make use of two management tools, the Public Value Scorecard and the Public Value Atlas. This dissertation contributes to a deeper understanding of the drivers and outcomes of public value perceptions and helps to close some knowledge gaps while stimulating further thought and action pertaining to the multiple aspects of public value.:CHAPTER 1: FRAMEWORK PAPER CHAPTER 2: PUBLIC VALUE REPORTING: ADDING VALUE TO (NON-) FINANCIAL REPORTING CHAPTER 3: DRIVERS OF SHARING ECONOMY SUPPLY AND DEMAND: THE ROLE OF INDIVIDUAL CHARACTERISTICS CHAPTER 4: ENTREPRENEURS’ AGE, INSTITUTIONS, AND SOCIAL VALUE CREATION: A MULTI-COUNTRY STUDY CHAPTER 5: TOO MUCH OF A GOOD THING?

Wie sollen Rechtssysteme auf Regeln reagieren, die Provider von Netzgemeinschaften wie Facebook oder World of Warcraft Nutzenden auferlegen? Das positive Recht gibt hierauf keine verlässliche Antwort. Erst ein Verständnis der Legitimität der Regeln ermöglicht ein Austarieren des Verhältnisses zwischen den Regelwerken von Netzgemeinschaften und Rechtssystemen. Nach Literaturstimmen sollen die Regeln durch außerrechtliche Mechanismen (z.B. direktdemokratische Verfahren), eine gerichtliche Kontrolle nach verfassungsrechtlichen Kriterien oder Zivilverfassungen legitimiert werden. Es ist aber zweifelhaft, ob Netzgemeinschaften legitime außerrechtliche Mechanismen schaffen können, ob sie wie Staaten behandelt werden sollten und ob Zivilverfassungen entstehen werden. Die Arbeit schlägt ein alternatives Modell vor: Im deutschen Zivilrecht zeichnet sich ein Legitimitätsmodell für private Regeln ab, das auf Regeln von Netzgemeinschaften anwendbar ist und als transnationale Schablone dienen kann. Danach werden die Regeln durch die Zustimmung und das Wohl der Nutzenden legitimiert. Letzteres gewährleistet ein Ausbeutungsschutz der Nutzenden in Form einer gerichtlichen Kontrolle. Die Anwendung des Modells führt zu folgenden Erkenntnissen: 1. Geschriebene Regeln sind schwach durch Zustimmung legitimiert. Eine gerichtliche Kontrolle nach vertragsrechtlichen Kriterien (bei Regelungen des Austauschverhältnisses zwischen Providern und Nutzenden) oder grundrechtlichen Kriterien (bei Verhaltensregeln) verleiht ihnen zusätzliche Legitimität. Die Kontrollintensität hängt von der Höhe des Ausbeutungsrisikos und der Existenz von legitimen außerrechtlichen Mechanismen ab. 2. Code-Regeln (z.B. Newsfeed- Algorithmen) sind auch nur schwach durch Zustimmung legitimiert. Gerichtliche Kontrollmöglichkeiten, die sie gegenüber Nutzenden legitimieren, müssen noch geschaffen werden. 3. Geschriebene und Code-Regeln sind illegitim gegenüber Nichtnutzenden, weil sie nicht auf deren Zustimmung beruhen. / How should legal systems respond to rules that virtual community providers such as Facebook or World of Warcraft impose on users? To answer this question, we must look beyond black letter law. Only an understanding of the legitimacy of these rules allows us to balance out their relationship with legal systems. Current scholarship theorizes their legitimacy as follows: Non-legal mechanisms (e.g. direct voting systems), judicial review according to constitutional principles, or digital civil constitutions may legitimize the rules. Yet, three points remain doubtful: whether virtual communities can develop legitimate self-governance mechanisms, whether they should be treated like states, and whether digital civil constitutions will effectively emerge. This work proposes an alternative legitimacy model: German private law reflects a legitimacy model for private rule-making applicable to rules of virtual communities which can serve as a transnational template. This model suggests that the rules can derive legitimacy from two sources: user consent and the common good of users, the latter ensured by judicial review protecting users against exploitation. This leads to the following key findings: 1. Written rules of virtual communities are weakly legitimized by user consent but derive additional legitimacy from judicial review. Contract law standard applies to rules that govern the bilateral exchange relationship between providers and users. General rules of conduct for users are checked against fundamental rights. The required intensity of review depends on the risk of user exploitation and the presence of legitimate self-governance mechanisms. 2. Rules embedded in computer code (e.g. newsfeed algorithms) are poorly legitimized by user consent. Judicial review procedures legitimizing them towards users still need to be established. 3. Both written rules and rules embedded in computer code are not legitimate towards non-users since non-users have not consented to them.
