The concept of corporate entrepreneurship continues to occupy the minds of scholars and practitioners alike. This is not surprising as corporate entrepreneurship constitutes a major driver of organizational revitalization, learning, and growth within large and medium size organizations. However, despite extensive research on corporate entrepreneurship, there is still confusion about the interplay of its macro- and micro-level constituents. To unveil how the structures, practices, and behaviors, which constitute entrepreneurship in large, diversified firms, interact, I utilize a systemic reasoning and link the notion of corporate entrepreneurship to diverse theoretical positions in the strategic management field including intraorganizational ecology, institutional theory, and configuration theory - links that have been so far neglected in the literature on corporate entrepreneurship. I develop my arguments in three complementary articles. In the first article, I provide a review of the theoretical framework that to a large extent underpins my research: the Bower-Burgelman process model. In the second article, I take a qualitative case study approach to analyze how micro-level practices affect the intraorganizational and external environment in favor of an entrepreneurial initiative. In the third article, I identify four different design types on the basis of a qualitative meta-synthesis, which reflect coherent constellations of managerial interpretive-schemes, structures, and systems that cultivate entrepreneurial behavior. In sum, this dissertation contributes to a new understanding of corporate entrepreneurship as a system of entrepreneurially behaving actors who are constrained and simultaneously enabled by a set of social, cultural, political, and structural context factors.
The Ili Delta in Kazakhstan is an important ecosystem that offers crucial wetland habitats for several bird species. However, the Ili River, the Ili Delta and the Balkhash Lake are suffering from water shortage due to climate change and human activities. The desertification of the Aral Sea, an obvious point of comparison to the Balkhash region, also involved the degradation of wetland habitats and the related loss of many bird species relying on these habitats. Therefore, water shortage at the Ili Delta may also be the reason for the loss of wetland habitats and bird species. In this study, bird species numbers, species abundances as well as bird diversity at different habitats in the Ili Delta were examined. There are many habitat types provided by the Ili Delta, for example reed bed vegetation, Tugay forest, bare soil floodplains along rivers and steppe. The results of this study showed that the central delta region with habitats of submerged reed vegetation showed the highest number of bird species and the greatest diversity. Threatened bird species at the Ili Delta were also observed only in these wetland habitats. Steppe habitats showed the lowest numbers of bird species and the lowest bird diversity. In general, all habitats at the Ili Delta are important for the ecosystem and essential for the bird species that depend on them for their survival. With expansion of arid steppe habitats due to water shortage, however, previous wetland habitats may be lost. Moreover, bird species that depend on these wetland habitats may also be lost. Therefore, protective measures for the Balkhash region in general and the wetland habitats at the Ili Delta and its distinct avifauna in particular are urgently needed.
Perfluoroalkyl and polyfluoroalkyl substances (PFASs) have been widely used since 1950 in various consumer products as well as in industrial applications owing to their unique properties, e.g. being hydrophobic and lipophobic at the same time. Nowadays, some of these persistent and man-made PFASs can ubiquitously be found in humans, wildlife and various environmental media. One prominent representative of concern, belonging to the subgroup of perfluorocarboxylates (PFCs) and their conjugate acids (PFCAs), is perfluorooctanoat (PFO) and its conjugate acid (PFOA). Because of its adverse effects on human health and its persistency in the environment industry has started to replace PFO(A) and related long chain chemicals (with seven and more fully fluorinated carbon atoms) with so-called short chain PFASs (less than seven fully fluorinated carbon atoms), including precursors of PFC(A)s. Also these short chain PFC(A)s are persistent and can already be found in humans, ground- and drinking water and in remote regions. However, knowledge gaps exist in understanding the partitioning and the resulting mobility of short chain PFC(A)s in the environment. This is due to the fact that partitioning data of PFC(A)s from standardised experiments can easily be biased by various artefacts, e.g. self-aggregation of the molecules. Therefore, the objectives of this thesis are (i) to quantify the partitioning of PFC(A)s into mobile environmental media, (ii) to show how results from non-standard tests can be used to assess substance properties of concern and (iii) to conclude on whether the environmental exposure to short chain PFC(A)s is of concern from a regulatory point of view. In the first part of this thesis, the environmental mobility of short chain C4-7-PFC(A)s was investigated by quantifying their partitioning under non-standardised semi-environmental conditions into mobile environmental media, focusing on water and air, and comparing it to long chain PFC(A)s. Results are: Partitioning between water and particles in the aeration tank, primary and secondary clarifier of a wastewater treatment plant (WWTP) showed no distinct differences for short chain PFC(A)s compared to their long chain homologues (Paper 1). In a water-saturated sandy sediment column short chain PFC(A)s were not retarded, whereas long chain homologues were retarded by sorption to the sediment (Paper 2). Atmospheric particle-gas partitioning showed a lower fraction sorbed to particles for short chain PFC(A)s compared to long chain ones in samples from a WWTP (Paper 3). Air-water concentration ratios based on samples from the tanks of a WWTP were found to be higher for short chain PFC(A)s compared to long chain PFC(A)s (Paper 1). Additionally, in a newly developed experimental set-up the water to air transfer was used to derive that the pKa of C4-11-PFCAs must be <1.6 instead of up to 3.8 as reported in the literature (Paper 4). Overall, in the investigated systems short chain PFC(A)s showed a higher mobility due to a more pronounced partitioning into mobile environmental media compared to long chain PFC(A)s. In the second part of the thesis it was shown how PFO(A) - owing to its persistent, bioaccumulative and toxic (PBT-)properties – was in the context of this thesis successfully assessed as a substance of very high concern according to the criteria of the European REACH Regulation (EC No 1907/2006) by using data from non-standard tests (Paper 5). In conclusion, based on the knowledge of the high environmental mobility of short chain PFC(A)s and taking into account the argumentation of the PBT-concern of PFO(A), environmental exposure to short chain PFC(A)s is of concern and existing knowledge is already sufficient to initiate measures to prevent emissions of short chain PFC(A)s and their precursors into the environment.
Sustainability and Justice: Conceptual Foundations and Cases in Biodiversity and Fishery Policy
(2014)
Sustainability aims at justice in a threefold sense: intragenerational justice, intergenerational justice, and justice towards nature. However, the justification, specific content and practical implications of justice claims and obligations in the sustainability context often remain underspecified. This dissertation therefore asks: How can the concept of justice be structured systematically? How can justice be specified in the context of sustainability? Which specific problems of justice arise in sustainability policy? And what are the respective contributions of (sustainability) economics and (sustainability) ethics? The five papers of this cumulative dissertation approach these issues from different angles, working at the conceptual level and at the level of cases from biodiversity and fishery policy. In Paper 1, a formal conceptual structure of justice is developed, which lists the conceptual elements of justice conceptions: the community of justice including claim holders and claim addressees, their claims (and corresponding obligations), the judicandum (that which is to be judged as just or unjust), the informational base for the assessment, the principles of justice, and on a more practical level, the instruments of justice. By specifying these conceptual elements of justice, it is possible to analyse and compare different conceptions of justice. In Paper 2, the normative dimension of sustainability is discussed in terms of justice. Based on the identification of certain core characteristics of the concept of sustainability, we determine the specific challenges of justice in the context of sustainability along the conceptual structure of justice (from Paper 1). Inter alia, we show that sustainability calls for the integration of justice claims in the relationships with contemporaries, future humans and nature in a non-ideal context characterized by uncertainty, systemic mediation and limits. Paper 3 addresses the contribution of economics to the assessment of trade-offs between intergenerational and intragenerational justice. Economic analysis can delineate the opportunity set of politics with respect to the two justice objectives and identify the opportunity cost of attaining one justice to a higher degree. While the two justices are primary normative objectives, the criterion of efficiency - when directed at the attainment of these justice objectives - has the status of a secondary normative objective. Paper 4 constitutes a case study, reconstructing the ´biopiracy´ debate from a justice perspective. The paper links to the so called Access and Benefit-Sharing framework of the Convention on Biological Diversity, and addresses the question, which problems of justice arise regarding the utilization of genetic resources and traditional knowledge, especially if associated with patenting. It is shown that the predominant perspective of justice-in-exchange is insufficient and therefore complementary conceptions, namely of distributive justice, corrective justice and structural justice have to be taken into account. Paper 5 empirically assesses the justice notions of stakeholders in the Newfoundland fishery, building on qualitative semi-structured interviews and a combination of inductive and deductive coding. A central result is that inshore fishers are seen as the main claim holders, with a claim to participate and being listened to, and the opportunity to make a living from the fishery. Recognition, participation and distribution are all important domains of justice in the context of the Newfoundland fishery. The paper also discusses the relationship between normative theorizing and empirical justice research. Overall, this thesis integrates ideal and non-ideal normative theorizing, economic analysis, empirical justice research and hints at institutional implementation in the debate on sustainability and justice.
The postal sector has a long monopolistic tradition in many countries; however, since the 1990s it has undergone considerable changes. At the beginning of that decade, the European Commission abolished exclusive rights within the postal system and opened up the market to new private postal providers and changes have continued to accelerate after two important European directives. Both directives were intended to improve the quality of service in the industry and to open up the market to competition. What has changed since the opening of the German postal market? A look at market shares measured by volumes of processed postal items, or by revenue, quickly reveals the prevailing dominance of the former monopolist Deutsche Post AG (DPAG). Despite an increasing number of market entries by private postal providers, it seems the German postal market is still characterized by the old monopolistic structures and that the aim of creating a competitive environment has not been fully achieved. This thesis deals with different competition issues from an economics perspective. The analyses are based on self-collected data and in-depth interviews conducted during on-site visits and thus provide first empirical evidence regarding the status quo in the German postal market.
Audit quality is of crucial importance because it underpins the integrity of financial markets and thus enables complex international transactions. However, despite extensive research on audit quality, the interaction between structures, practices, and behaviors within accounting firms still remains a ´black box´. To open up the ´black box´ I draw on insights from the field of error management which has been highlighted to be central to gain a better understanding of audit quality. In this dissertation, I develop my arguments in three articles that build on each other. In the first paper, I systematically review the literature on the antecedents of audit quality and I suggest future research directions. In the second paper, I take an inductive case study approach to gain an in-depth understanding of error management in accounting firms. The resulting socio-cognitive model of error management informs both the field of error management, as well as the field of audit quality. In the third paper, I examine a crucial component of the socio-cognitive model: the individual. In a two-phase mixed methods study I investigate individual differences in error management and their implications for learning and performance. Taken together, the three articles of this dissertation contribute by providing an innovative approach to our understanding of both error management and audit quality.
The doctoral thesis deals with future challenges that the tourism market has to face on a global level. The problem is treated from different perspectives and with different thematic foci. Thematically, the thesis approaches both global changes in the tourism market and further developments of the research methodology. The methodological repertoire includes a Delphi survey in combination with a focus group, mobile ethnography in conjunction with participant observation and contextual interviews, and a quantitative online survey.
This dissertation offers three different perspectives on agency and institutional change. Within three different articles these perspectives are presented and discussed. In the following these three articles are introduced: Article I: Competing concepts of power in institutional theory make the analysis of institutional change challenging. On the one hand, the assumption of powerful institutions leaves little space for agency and institutional change; while on the other hand, the assumption of powerful actors allows for agency but contradicts the fundamental assumption of institutional theory as stated before. This article wishes to propose a concept of power that is consistent with institutional theory and preserves core institutionalist assumptions, but still offers an explanation for agency and institutional change. Article II: This study examines a case of embedded agency from the German accounting industry, which existing approaches of the paradox of embedded agency cannot explain. Based on an instrumental case study, this paper will provide a new explanation of embedded agency by highlighting the interaction between the different actors of an organizational field. Article III: Based on a dialectical perspective on institutional change, this paper studies the transformation of the German accounting industry covering the time period from 2000 to 2012. Corresponding to Seo and Creed (2002), this article identifies “intrainstitutional conformity that creates interinstitutional incompatibilities”, “legitimacy that undermines functional efficiency”, and “isomorphism that conflicts with divergent interests” (Seo & Creed, 2002, p. 226) as the drivers for recent change in this organizational field. The study provides an explanation of endogenous change that does not rely on institutional agency in explaining institutional change.
Rethinking Gamification
(2014)
Gamification marks a major change to everyday life. It describes the permeation of economic, political, and social contexts by game-elements such as awards, rule structures, and interfaces that are inspired by video games. Sometimes the term is reduced to the implementation of points, badges, and leaderboards as incentives and motivations to be productive. Sometimes it is envisioned as a universal remedy to deeply transform society toward more humane and playful ends. Despite its use by corporations to manage brand communities and personnel, however, gamification is more than just a marketing buzzword. States are beginning to use it as a new tool for governing populations more effectively. It promises to fix what is wrong with reality by making every single one of us fitter, happier, and healthier. Indeed, it seems like all of society is up for being transformed into one massive game. The contributions in this book offer a candid assessment of the gamification hype. They trace back the historical roots of the phenomenon and explore novel design practices and methods. They critically discuss its social implications and even present artistic tactics for resistance. It is time to rethink gamification!
The German market for corporate bonds has experienced an unprecedented growth over the last decade. As a growing number of German firms have seized the opportunity to issue debt securities to the market, the need arises to evaluate their attempts to provide bondholders with private corporate information. This doctoral thesis centers on a research interest concerning the extent and effectiveness of corporate disclosure directed at the German bond market. It delivers unprecedented insights into bondholder relations practices and is thought to establish this topic as a research field that is complementary to previous work on shareholder-related disclosure. Taking information asymmetries between firms and bondholders as a basis, the empirical analyses are based on various arguments from the voluntary disclosure theory as well as from principal-agency and related frameworks. In essence, most parts of the thesis follow the key assumption that bondholders demand higher premiums for opaqueness and potentially detrimental behavior on behalf of a bond issuer’s management. The analyses deliver new insights into the role of corporate disclosure and close a gap between bondholder relations and financial as well as shareholder-related disclosure. They contribute to the stream of research that is concerned with corporate disclosure and its relationship to the cost of capital, the cost of debt, and even more specifically the yield (spread) of corporate bonds.
Scaling Strategies of Social Entrepreneurship Organizations – an Actor-Motivation Perspective
(2014)
Despite their sometimes ingenious solutions, many social entrepreneurs fail to scale which is at odds with their overall objective of social change. Yet, though considered highly important in practice, scaling is still under-researched. Taking this imbalance as a starting point, my PhD thesis contributes to the social entrepreneurship literature by shedding new light on the role of the actor-motivation in scaling social ventures. Put together, papers 1-3 try to answer the general research questions of how do actors and their specific motivations, particularly the social entrepreneur, influence the scaling strategies (and success) of social ventures? Based on a brief review of the literature on scaling, I identify social franchising as a promising scaling strategy that requires more research. Here, paper 1 argues that the social mission of the involved actors can serve as an informal functional equivalent to formal contracts as well as a means to safeguard the local small group logic. Paper 2 discusses the effects of stewardship on social franchising coming to the conclusion that stewardship relationships may impede speed of and degree of scaling. Based on these insights, paper 3 more closely analyzes the motivations of social entrepreneurs in a post-founding stage. It empirically constructs a taxonomy of (social) entrepreneurs based on their motivations. To this end, paper 3 employs a three-step methodological approach that combines the inductive insights from 80 interviews with entrepreneurs with a statistical cluster analysis. Following, this paper then discusses contributions of and implications for scaling research as well as to social entrepreneurship, entrepreneurship, and management research.
This PhD dissertation thesis aims to analyse and discuss how a company can interact with its supply chain stakeholders to facilitate the development of sustainable supply chains. The research is based on empirical and conceptual work and contributes to the field of corporate sustainability, supply chain management and its intersection. The thesis develops a conceptual framework to analyse four organisational spheres of interaction (inter, intra, supra and sub) in sustainable supply chain management (SSCM). Thereby, further insights into risk and opportunityoriented approaches of companies to SSCM are provided.
This dissertation concerns the question of how economics can contribute to the analysis of trade-offs between values (or normative objectives). The analysis is illustrated for the case of policies that pursue the goal of sustainability. Methodologically, this is done by reflecting economic concepts in light of philosophical theories and using generic models to analyze trade-offs between particular values. In sum, the work shows how economics can help in analyzing the factual relationships between values by clarifying the set of feasible acts and outcomes. The first paper of this cumulative dissertation concerns the question what a general definition of efficiency with respect to normative objective implies about relationships between two values. In order to conceptualize relationships between values carefully, the analysis distinguishes instrumental from intrinsic values and discusses the question whether there is one intrinsic value (value monism) or many intrinsic values (value pluralism). Next, a small economic model is used to show that there can be different relationships between values such as win-win relationships and trade-offs in value-efficient states if there are three or more values. Further, the distinction between Pareto-efficiency (based on individual preferences) and value-efficiency (which can also include non-preference values) is used to study relationships between values. The second paper uses the definition of sustainability as inter- and intragenerational justice to discuss the relationship between these two objectives. The general aim of this paper is to discuss what economic concepts can contribute to the discussion of tradeoffs between justices. For this, a syntax of the concept of justice is employed, different relationships between justices are defined and economic concepts such as scarcity, efficiency and opportunity costs are transferred to the justice context. One result from this analysis is that there must be a trade-off between these two justices in such respective efficient outcomes. The third paper concerns an intertemporal mechanism leading to the well-known equity-efficiency trade-off in an intergenerational setting. For this, two central characteristics of intergenerational policy making are taken into account: irreversibility and ignorance (or unawareness). A pertinent example is the irreversible use of fossil fuels before and after the discovery of the effect of CO2 emissions on climate change. The trade-off between Pareto-efficiency and intergenerational equity that results from these two characteristics is shown in a model with two non-overlapping generations which use a non-renewable resource. In the model there is initial unawareness about an intergenerational externality from resource use that is only discovered after the irreversible use of the resource. A central result of the paper is the trade-off between intergenerational equity and efficiency that emerges if initially unknown sustainability problems arise after irreversible policies have been enacted. The fourth paper concerns the question what the concept of merit goods can contribute to discussions of sustainability. For this, the history of the concept is discussed, then merit goods are defined and connected to the philosophical literature on different conceptions of well-being. In the next step different challenges and opportunities of merit good arguments are discussed for the sustainability context. For example, it becomes clear that merit good arguments concern conceptions of well-being and do not directly concern the aspect of intergenerational distribution in sustainability problems.
Research in work and organizational psychology frequently conducts studies based on self-report questionnaires. Evidence of the reliability and validity of these measures has to be provided based on thorough research in order to be certain that meaningful conclusions can be reached. Recently, latent variable approaches have been introduced that provide new opportunities to examine the instruments and determine if they are suitable to obtain meaningful results. They also offer new approaches to investigate the relationships between constructs, particularly when assessed over time. The research conducted in this PhD thesis and reported in three papers aims at utilizing these opportunities to examine the measurement properties of a selection of self-report questionnaires and to address conceptual questions regarding the validity of these instruments. In the first paper, the structure of two five-factor personality inventories was examined using Confirmatory Factor Analyses (CFA) and Exploratory Structural Equation Modeling (ESEM). Both methods were applied to construct better-fitting, though more complex models based on data from two questionnaires (NEO PI-R and 16PF) completed by 620 respondents. The impact on the construct validity of the inventories was assessed. Generally, scores derived from either method did not differ substantially. When applying ESEM, convergent validity declined but discriminant validity improved. When applying CFA, convergent and discriminant validity decreased. We conclude that using current personality questionnaires that utilize a simple structure is appropriate. In the second paper, the nature of and reason for the relationship between a presence of a calling and three aspects of career preparation (career planning, decidedness, and self-efficacy) were investigated. Data were collected in three waves of a diverse sample of German university students (N = 846) over one year. Latent growth analyses revealed that calling was positively related with all career preparation measures. The slope of calling was positively related to those of decidedness and self-efficacy but not to planning. Cross-lagged analyses showed that calling predicted a subsequent increase in planning and self-efficacy. Planning and decidedness predicted an increase in the presence of a calling. In the third paper, the measurement properties of an adapted protean career orientation scale were examined. We present a series of studies that (1) establish the scale’s unidimensionality and measurement invariance across gender within separate samples of students and working professionals as well as measurement invariance between both samples; (2) demonstrate measurement invariance and differential stability over six months among students and professionals; (3) show that a protean career orientation partially mediates the relationship between personality dispositions (i.e., proactive personality, core self-evaluations) and proactive career behaviors and career satisfaction among students and employees; (4) demonstrate that a protean career orientation possesses incremental predictive validity regarding proactive career behaviors and career satisfaction beyond personality dispositions among students and employees; and (5) based on a cross-lagged study among employees, we show that career satisfaction predicts a protean career orientation but not vice versa. In summary, the research presented here provides researchers in the field of work and organizational psychology with a thorough assessment of the measurement properties and aspects of validity of these self-report questionnaires. The findings demonstrate their suitability for future research studies conducted in work and organizational psychology as well as for practical applications.
Business Models for Sustainability Innovation: Conceptual Foundations and the Case of Solar Energy
(2013)
This dissertation deals with the relationships between the increasingly discussed business model notion, sustainability innovation, and the business case for sustainability concept. The main purpose of this research is to identify and define the so far insufficiently studied theoretical interrelations between these concepts. To this end, according theoretical foundations are developed and combined with empirical studies on selected aspects of the solar photovoltaic industry. This industry is particularly suitable for research on sustainability innovation and business models because of its increasing maturity paired with public policy and market dynamics that lead to a variety of business model-related managerial and entrepreneurial business case challenges. The overarching research question is: How can business models support the commercialisation of sustainability innovations and thus contribute to business cases for sustainability? A theoretical and conceptual foundation is developed based on a systematic literature review on the role of business models in the context of technological, organisational, and social sustainability innovation. Further, the importance of business model innovation is discussed and linked to sustainability strategies and the business case for sustainability concept. These theoretical foundations are applied in an in-depth case study on BP Solar, the former solar photovoltaic subsidiary of British Petroleum. Moreover, because supportive public policies and the availability of financial capital are known to be the most important preconditions for commercial success with innovations such as solar photovoltaic technologies, the solar studies include a comparative multiple-case study on the public policies of China, Germany, and the USA as well as a conjoint experiment to explore debt capital investors’ preferences for different types of photovoltaic projects and business models. As a result, the main contribution of this work is the business models for sustainability innovation (BMfSI) framework. This framework is based on the idea that the business model is an artificial and social construct that fulfils different functions resulting from social interaction and their deliberate construction. The BMfSI framework emphasises the so-called mediating function, i.e. the iterative alignment of business model elements with company-internal and external requirements as well as with the specific characteristics of environmentally and socially beneficial innovations. Against this backdrop, it becomes clear that practically-oriented knowledge based on BMfSI research might provide new and effective ways to support the achievement of corporate sustainability.
