Public sector reforms have made the corporatization of public services a global phenomenon. Worldwide, public corporations provide critical services and infrastructures for citizen’s daily lives. In many countries, public corporations represent a substantial portion of both gross domestic product and employment. The COVID-19 pandemic has further highlighted the high societal relevance of public corporations in areas such as social/health care, mobility, and digitalization. The United Nation’s 2030 Agenda for Sustainable Development emphasizes public corporations as key actors with role-model functions in the promotion and implementation of the Sustainable Development Goals. Standing midway between in-house provision and privatization, the corporatization of public services has high potential to improve public service performance by enhancing managerial autonomy and professionalism while maintaining political control. However, the independent corporate status of public corporations and their operations outside the traditional administrative system induce far-reaching governance challenges. Being a substantial research and practice area, public corporate governance aims to provide perspectives on how public authorities could exercise their ownership function in order to ensure that public corporations act in accordance with public interest. It is executive directors in particular—occupying positions of great autonomy, power, and discretion—who play a key role in the governance of public corporations. This field, however, still has significant research gaps—one of which is the significant lack of theoretical understanding about how far different governance mechanisms could effectively mitigate critical issues in public corporate governance that are associated with the higher autonomy of executive directors operating in either profit-making or not profit-making public corporation forms. The overarching research connections of this dissertation aims to enhance the theoretical understanding of instrumental and personnel governance of executive directors in corporatized public service provision and to derive theoretical perspectives on governance differences between profit-making and not profit-making public corporation forms. Overall, this dissertation makes three key contributions. First, it elaborates novel perspectives of different governance mechanisms in the public corporation context by introducing a conceptual differentiation of instrumental and personnel governance. In this context, the dissertation enhances theoretical understanding and provides empirical findings on the effects of self-regulation and law as well as on the role of executive director characteristics in recruitment, pay, and turnover. Second, the presented work broadens the theoretical understanding of the interdependencies between different personnel and instrumental governance mechanisms, providing insights regarding their critical impact on the realization of policies and good public corporate governance at the executive director level. Third, this dissertation enriches the recent theoretical debates about the governance of decentralized public sector organizations by focusing on the increasingly relevant but still widely neglected organizational type “public corporation” and by accounting for governance differences between profit-making and not profit-making public corporation forms.

The recurrent business scandals of the past decades have been a wakeup call for research and practitioners regarding the crisis organizational ethics is in. In an effort to remedy the situation many organizations have relied on the implementation of compliance- and/or integrity-oriented ethics programs. However, observations from practice and research show that the results of such programs are mixed, and it is still unclear when and why they are effective to reduce misconduct and promote ethical behavior. In this dissertation an answer to this question is sought. Building on literature that considers the overall organizational ethical context, I hypothesize that ethical culture can explain when and why compliance and integrity strategies are successful at preventing misconduct and promoting ethical behavior. To examine the proposed relationship, two new measures for ethics strategies and ethical culture are developed and validated. The Ethics Strategy Measure (ESM) is the first validated instrument to measure the strategic focus of ethics programs (compliance vs. integrity). The German Ethical Culture Scale 2.0 (GECS 2.0) is a 10-dimensional advanced measure of ethical culture. In three studies the psychometric properties, convergent and predictive validity of the two instruments are shown. Consequently, in four consecutive studies the new measures are applied to test whether the dimensions of ethical culture mediate the relationship between compliance and integrity strategies and (un)ethical behavior. The results show that the effects of compliance and integrity strategies on unethical behavior can fully be explained through their effect on the dimensions of ethical culture. Further, it is shown that compliance strategies are not able to inspire ethical conduct, while integrity strategies are. This relationship is also fully mediated by the dimensions of ethical culture. Different ethical culture dimensions emerge as drivers of different mediated effects. Implications for research and practice are discussed.

This dissertation is dedicated to extending scholarly understanding of organizational transformation in the context of disruptive change. For this purpose, three independent studies explore both organizational- and individual-level aspects of organizational transformation. In doing so, this dissertation integrates two literature streams – disruptive innovation theory and organizational identity. Study 1 lays the ground by providing a descriptive, thematic analysis of organizational transformation induced by digital innovations and technologies. The paper systematically reviews 58 articles to critically assesses where, how and by whom research on digital transformation is conducted and how it unfolds at the organizational level. Studies 2 and 3 are located at the intersection of disruptive innovation adoption and organizational identity in the context of incumbent firms. Both studies apply an inductive, field-based single case design and primarily build on qualitative data gathered from 39 (Study 2) and 35 (Study 3) semistructured personal interviews at a major German car manufacturer. Study 2 examines how organizational identity change unfolds in an incumbent attempting to adopt multiple different disruptions at the same time, while Study 3 moves more towards the individual-level and attempts to understand how and why organizational members respond heterogeneously to disruption. Overall, this dissertation contributes in the following ways: (1) Studies 1 and 2 extend the conceptual- and organizational-level knowledge of disruptive innovation adoption during organizational transformation. In particular, Study 2 shows that different drivers of identity-induced organizational transformation become observable, dependent on the nature of a disruption, (2) Studies 2 and 3 extend the individual-level knowledge of organizational member’s attitudes and behavior during identity-threatening organizational transformation. For this purpose, Study 3 develops a typology which gives evidence for the existence of three types of member’s sensitivities and shows that identity and knowledge function as cognitive frames of reference to interpret change, whereas culture is seen as a contextual factor to support the transformation of identity and knowledge.

Confidence judgments and decision making are part of everyday life. In an ideal world, people would assess their skills and knowledge accurately and base their decisions only on rational deliberations. Yet, this is often not the case. Confidence judgments in own skills or performance are often biased (e.g., Dunning, 2011; Moore & Healy, 2008; Moore & Schatz, 2017; Sanchez & Dunning, 2018; Pikulina, Renneboog, & Tobler, 2017; Michailova & Schmidt, 2016). Also, people tend to deviate from rational decision strategies (e.g., Achtziger & Alós-Ferrer, 2014; Alós-Ferrer, Hügelschäfer, & Li, 2016, 2017; Charness, Karni, & Levin, 2010; Erev, Shimonovich, Schurr, & Hertwig, 2008; Fiedler, Brinkmann, Betsch, & Wild, 2000; Tschan et al., 2009). Therefore, the research aim of the present dissertation was twofold. In the first chapter of the present dissertation I investigated confidence judgments in own skills and the confidence bias, the processes underlying these confidence judgments, and the influences of gender and monetary incentive on confidence judgments. The second aim was to investigate the influence of goal and implementation intentions on rational decision making and how this influence is reflected in the neural correlate of reinforcement learning. A common finding in research on confidence judgments is the confidence bias (e.g. Moore & Schatz, 2017; Moore & Healy, 2008; Pikulina et al., 2017; Sanchez & Dunning, 2018; Lebreton et al., 2018). In most cases, the confidence bias reflects overconfidence, which means that people’s subjective confidence exceeds their actual ability or performance (Fischhoff, Slovic, & Lichtenstein, 1977). In some cases, there is also evidence for underconfidence, suggesting that people underestimate their abilities (Kruger & Dunning, 1999; Kruger & Burrus, 2004). Gender is an important predictor of the confidence bias. Underconfidence is more prevalent in females, whereas males often display overconfidence (e.g., Barber & Odean, 2001; Hügelschäfer & Achtziger, 2014; Niederle & Vesterlund, 2007). In Study 1, I investigated the processes underlying confidence judgments and the confidence bias by means of response times, and I examined potential gender differences. Participants answered general knowledge questions and judged their confidence on the correctness of each answer. Participants had overall a good sense of whether their answer was correct or incorrect. This was reflected by higher confidence judgments on correct answers compared to incorrect ones. The analysis of response times on the confidence judgments revealed that male participants who took longer to judge their confidence were made more accurate judgments than males who responded quickly. This relationship was not found for females. In Study 2, half of the participants received a monetary incentive for good performance in the general knowledge test. The monetary incentive for performance increased the time invested in both tasks (the knowledge questions and the confidence judgments). However, this increased effort did not lead to better performance on the knowledge questions, nor did it yield more accurate confidence judgments. The response times suggested that males who invested more time in the confidence judgments were more accurate (as in Study 1). However, the opposite was true for females. The more time females invested in their judgment the more underconfident they were. This influence of the response time on the confidence bias was only found for incentivized participants. In Study 3, the accuracy of the confidence judgment was incentivized. Contrary to the expectations, the monetary incentive did not reduce the confidence bias but led both males and females to be overconfident. In this study, the response time on the confidence judgment did not predict the confidence bias. On the whole, the results demonstrate that (a) the processes of confidence judgments differ between females and males, and (b) the effectiveness of monetary incentives for improving the accuracy of confidence judgments depends strongly on the incentive being contingent on the performance in the task at hand. The second chapter of the present dissertation investigated the influence of goal and implementation intentions (P. M. Gollwitzer, 1999) on rational decision making (see also Hügelschäfer & Achtziger, 2017). The impact of intentions was examined by the neural correlate of reinforcement learning, i.e. the feedback-related negativity (FRN; Holroyd & Coles, 2002). Participants worked on a probability updating task in which the optimal strategy to maximize the expected payoff was to follow Bayes’ rule by integrating new information with prior probabilities (Bayes & Price, 1763). The optimal decision rule conflicted with a simpler suboptimal decision strategy, i.e. the reinforcement heuristic (see Achtziger & Alós-Ferrer, 2014; Charness & Levin, 2005). The goal and implementation intention manipulation was proposed to control the automatic process of the reinforcement heuristic and hence foster rational decision making. The results showed that the goal intention and the implementation intention had no influence on the number of reinforcement errors (in contrast to the findings of Hügelschäfer & Achtziger, 2017). However, both, the goal and implementation intentions increased the amplitude of the FRN which, on the neural level, indicated a stronger reliance on the reinforcement heuristic than in the control group. The findings shed some light on the impact of goal and implementation intentions on rational decision making. They demonstrate that careful consideration of the use of intentions as an intervention for improved decision making is required to avoid undesired side-effects. Taken together, the present dissertation provided new insights into the processes underlying confidence judgments, the confidence bias, rational decision making, and its neural correlates.

People face economic decisions on a daily basis. Quite often, these decisions involve high stakes and some degree of personal risk, as choices produce real consequences that set the course for future actions. Although decades of decision research in the intersection of psychology, behavioral economics, and neuroscience have much advanced our knowledge about the psychological underpinnings of economic decisions, several academic disputes remain unsettled. Indeed, surprisingly little is known about the role of motivation and volition in guiding economic decisions. Certainly, people’s motives, goals, and their expectations of attractive rewards are important drivers of decision making. Yet, motivation and volition cannot be reduced to goals and incentives. The cognitive mechanisms underlying economic decisions are rather complex, and motivation and volition may impact decisions at the level of these cognitive processes. This dissertation considers the role of motivation and volition in economic decisions by examining the impact of experimentally induced motivational and volitional states of mind on economic choices and decision processes. Using different methods and decision making paradigms, four experiments provide novel evidence that informs the ongoing debates in motivation research, decision science, and psychophysiology. In short, Experiments 1a and 1b explore the possibility of interactive effects between motivation, volition, and financial incentives in determining economic performance. Moving on to the level of decision processes, Experiment 2 examines the impact of motivation and volition on decision processes under risk. Decision times, eye movements, and pupil dilations provide process measures of cognitive effort, pre-decisional information search, and affective arousal, respectively. Finally, Experiment 3 investigates how particular decision attributes relate to affective and motivational processes in decisions under risk. The findings of the present dissertation can be summarized in terms of four main conclusions. First, incentives are effective for improving economic performance when the payment of attractive monetary rewards is contingent on performance. Yet, higher incentives do not further improve performance. Second, the experimental manipulation of motivational and volitional mindsets does not directly affect choices, but notably impacts decision processes. Third, the influence of motivation and volition on economic decisions appears to depend on the appropriate incentivization of the task at hand. Fourth, risky choice attributes that entail no gain at all, i.e., zero-outcomes, elicit high levels of affective arousal and motivational avoidance tendencies that guide selective attention and decision making in the lottery choice paradigm. The implications of these findings are discussed for theory development in motivation research and decision science, as well as in terms of their practical implications for decision making in managerial contexts and other high-stakes decision environments.
