Within the last 25 years, researchers identified different destructive behaviors of leaders, various outcomes and some major reasons for their emergence. However, the attention given to personality traits in this context does not yet reflect their relevance as excellent predictors of (bad) behavior. Further, the field of Human Resource Management (HRM) could derive valuable measures against destructive leadership, if more was known about the role of managers’ and followers’ ‘bright’ and ‘dark’ personality traits in such situations. Consequently, this dissertation combines research on leadership and three HRM functions (i.e., acquisition, placement, motivation) and, in three separate empirical studies, examines the role of personality traits in explaining destructive management and leadership.
The first contribution is an experimental vignette study on hiring recommendations of Dark Triad supervisors for Dark Triad applicants. Based on the Similarity-Attraction Paradigm, results show that supervisors who are high in Dark Triad traits (i.e., Narcissism, Psychopathy, and Machiavellianism) tend to recommend applicants that also show high levels in those traits. This bias leads to decisions in personnel selection processes that prefer individuals with ‘dark’ traits, which are then likely to result in detrimental actions, e.g. counterproductive work behavior.
The second study introduces the Sensory Processing Sensitivity trait (SPS) into the context of expatriate management. Although SPS is known to relate to positive outcomes, individuals high in SPS tend to be easily overwhelmed and stressed by new environmental stimuli. This study draws on the Conservation of Resources Theory and uses a cross-sectional design to find that the ‘dark’ side of SPS prevails in the expatriate context and that it indirectly and positively relates to expatriates’ turnover intentions via social capital and stress.
In the third study, I examine resistance behaviors of followers when their supervisor exploits them. Based on complementary Person-Supervisor Fit, I expect that there are followers with certain interaction styles (giver, taker, or matcher) that tend to resist in a more constructive way than others do. Using an experimental vignette approach, results show that givers express higher levels of overall resistance caused by an increase in constructive resistance. Takers and matchers show less constructive, but more dysfunctional resistance.
The results of this dissertation shed light on the relevance of ‘bright’ and ‘dark’ personality traits in the context of destructive leadership and management. They suggest various possibilities for HRM to protect the organization and its employees from negative consequences.
This cumulative dissertation consists of five research contributions considering different questions for forecasting price decline events for consumer goods. The main goal of the dissertation is the development of a methodological framework to derive economically beneficial buying recommendations on the basis of historic minimum price time series that support price-sensitive customers in scheduling their buying decisions when purchasing homogeneous goods. The central steps for the development, configuration and application of a suitable forecasting methodology are described in the five research papers. The first article develops a probabilistic forecasting methodology and shows opportunities and challenges when evaluating decision recommendations. Article 2 exemplifies the developed statistical procedure and shows that generated decision recommendations are economically viable using a real sample from the German e-commerce market. The third article discusses the economic and statistical implications when setting a price decline threshold in more detail and shows that the economically optimal threshold can be determined based on the historic minimum price time series. Additionally, an approach is presented that produces precise estimates based on the incomplete time series 90 days after the product’s market entry. Article 4 develops an additional approach to improve target price alarms on price comparison sites. The fifth article extends the methodological spectrum for forecasting price change events and shows that identified dynamics are generalizable over time and product groups. The exploitation of these dynamics leads to more precise and economically relevant buying recommendations.
This dissertation endeavours to bring together already formulated and future starting points in the research of wisdom-oriented management. While modules I and II focus on practical wisdom with regard to corporate sustainability, module III focuses on the concept of practical wisdom with regard to decision-making processes in companies. Module IV provides the fundamentals of business ethics and wisdom-oriented thinking in relation to management education.
