Micro- and small enterprises are of great importance for the economic growth in developing countries, as they contribute to employment creation and innovation. In light of their economic relevance, several approaches to support micro- and small enterprises have emerged, including building human capital through business trainings. However, the effects of existing business trainings on entrepreneurial success have so far been limited. One promising alternative training approach that has emerged in the last years is personal initiative training, which teaches self-starting, future-oriented, and persistent entrepreneurial behavior. This dissertation helps to improve the understanding of personal initiative training by shedding light on the mechanisms through which it affects business success, on supporting factors, and on its long-term impacts. Chapter 1 provides an overview on the topic of personal initiative training for entrepreneurs in developing countries. Chapter 2 introduces personal initiative training and other proactive behavior trainings in various contexts of work, including entrepreneurship. The chapter presents action regulation theory and the theory on personal initiative as the theoretical foundation of the training. In addition, the chapter provides insights into training and evaluation methods and makes recommendations for the successful implementation of personal initiative training. Chapter 3 offers a first answer to the question how personal initiative after training can be maintained over time. The chapter introduces training participants´ need for cognition as beneficial factor for post-training personal initiative maintenance. Chapter 4 explains how action regulation trainings like personal initiative training contribute to poverty reduction in developing countries by supporting entrepreneurial success. Chapter 5 enlarges upon the topic of personal initiative training for entrepreneurial success in developing countries. The chapter focuses on how personal initiative training supports female entrepreneurs in developing countries by helping them to overcome the uncertainty involved in entrepreneurial actions. Chapter 6 summarizes the overall findings and illustrates the theoretical and practical implications that result from this dissertation. In sum, this dissertation makes a contribution to the better understanding of personal initiative training and its effects on entrepreneurship in developing countries and thereby helps to create effective interventions to combat poverty in developing countries.
Im Kontext der demografischen Entwicklung müssen Instrumente der Mitarbeiterbindung neu hinterfragt werden. Um die Fachkräfte, die auf dem Arbeitsmarkt nicht mehr verfügbar sind im Unternehmen zu halten, müssen HR-Praktiken im Unternehmen möglicherweise an altersspezifische Bedürfnisse angepasst werden. Es kann angenommen werden, dass die Bindung an die Organisation – bedingt durch Entwicklungsverläufe über die Lebensspanne – in verschiedenen Altersgruppen von unterschiedlichen Faktoren beeinflusst wird (Conway, 2004; Finegold, Mohrman & Spreitzer, 2002). Ziel dieser Arbeit ist es, entsprechende altersbedingte Veränderungen und Priorisierungen zu identifizieren, die einen differenziellen Einfluss auf Mitarbeiterbindung haben. Aus Phasenmodellen der Entwicklungspsychologie werden diese Differenzierungen herausgearbeitet, um daraus Hypothesen zu unterschiedlichen Zusammenhangsstärken situativer Entstehungsbedingungen und affektiver Bindung herzuleiten. Zur Überprüfung der Hypothesen wurden zwei empirische Studien durchgeführt: 1) In einer unternehmensinternen Untersuchung wurden 121 Mitarbeiter in den Altersgruppen 20 bis 30, 31 bis 45 und 46 bis 65 Jahre befragt; 2) Im Rahmen einer Online-Befragung wurden 420 Arbeitnehmer der gleichen Altersgruppen befragt. Die angenommenen moderierenden Effekte wurden mit Hilfe verschiedener Methoden überprüft. Zunächst wurden moderierte Regressionsanalysen gerechnet, um die linearen Hypothesen zu überprüfen. Aus diesen Analysen zeigten sich in beiden Studien kaum Effekte. Eine Subgruppenanalyse, in der die Korrelationsstärken der drei Altersgruppen miteinander verglichen wurden, zeigte zum Teil substanzielle Unterschiede in den Zusammenhangsstärken zwischen Entstehungsbedingungen und affektivem organisationalem Commitment (ACO), teils aber auch stabile Zusammenhänge über alle Altersgruppen hinweg. Wenige Ergebnisse zeigten sich in beiden Studien gleich. Einige Ergebnisse widersprechen den Hypothesen: So zeigte hier die Möglichkeit zu generativem Verhalten am Arbeitsplatz auch in der jüngeren Gruppe substanzielle Zusammenhänge mit ACO, während die gebotene Entwicklungsmöglichkeiten auch in der älteren Gruppe starke Zusammenhänge mit ACO zeigten. Auf Besonderheiten und Unterschiede der beiden Studien wird eingegangen, Implikationen für weitere demografierelevante Forschung werden aufgezeigt und Hinweise für die Gestaltung des Personalmanagements gegeben. Insbesondere untermauert die Arbeit die Notwendigkeit a) einer individuellen Betrachtung von Mitarbeitern jeden Alters, um Bindung zu fördern sowie b) einer Berücksichtigung des jeweiligen Unternehmenskontexts.
This dissertation focused on the nature and role of organizational practices for the employment of older people and the extension of their working lives. The set of four articles is driven by the objective to further deepen our understanding of how organizations can facilitate ageing at work to the benefit of both, employees and employers. Findings are empirically based on qualitative expert interview data from Germany and the U.S. and several quantitative field studies among older employees in Germany. To bridge gaps in measurement of organizational practices related to aging at work, this dissertation proposes a new comprehensive, multifaceted, and thoroughly conceptualized measure of organizational practices related to aging at work, the Later Life Workplace Index (LLWI). Through the course of the four articles the LLWI is conceptually developed based on qualitative interview data, operationalized, validated based on multiple field studies among older workers, and applied in a multi-level study among older employees of 101 organizations. Results suggest that organizational practices are not uniform, but multifaceted in their presence within organizations and their effects for the employment of older workers. The LLWI distinguishes nine domains of practices including an age-friendly organizational climate, work design, individual development, and practices tailoring the retirement transition. Thus, it may lay the foundation for more granular organizational level research in the field. Further, this dissertation’s fourth article applies the LLWI and argues based on person-environment fit and socio-emotional selectivity theory that organizational practices address different individual needs and, thus, affect employment depending on employees’ individual characteristics. Results suggest that older employees’ retirement intentions are effected by individual development, transition-to-retirement, and continued employment practices depending on their health resources. Application of the new measure in practice to improve organizations’ response to the aging workforce and opportunities for future research based on the LLWI are discussed.
