Following Joseph Schumpeter's conception of innovation as ‘new innovations’, this chapter contends that innovations that transform lives in developing countries of Southern Africa are not radically new and different novelties but rather ‘new combinations’ at the interface of new materialisations (creative expression) and exploitations of new opportunities (entrepreneurship). We argue that this posture is not a contestation of the reality that novelty enter the system through the development of new technologies, processes and new ways of organising, but rather such novelty is a process of recombining existing elements in new ways. I build on this argument to demonstrate that in resource-poor contexts where institutional voids frustrate entrepreneurs' potential to deploy innovation capabilities for generating groundbreaking innovation, innovations and entrepreneurship are outcomes of ‘tinkering’, improvision and refinement of unsophisticated creative ideas. Drawing on exemplars from health, education, finance and poverty alleviation interventions that support sustainable human development, I also demonstrate that high knowledge-intensive entrepreneurship (KIE) and low knowledge-intensive frugal innovations are mutually constitutive and recursive outputs of the interaction of knowledge application and innovation conversion rather than serial processes of cause and effect. Using combinative innovation, internal coupling and combinative capabilities as heuristics for understanding the entrepreneurship–innovation nexus, I provide empirical support to the view that entrepreneurial effectuation, new combinations, bricolage and improvision constitute useful cognitive arena for the conversion of entrepreneurial and innovation behaviours, practices and processes into KIE and frugal innovation outputs.

This paper aims to investigate the interconnectedness of redenomination risk premiums across the four main European sovereign bond markets (France, Germany, Italy and the Netherlands).

The authors used the time-varying parameter vector autoregressions method to achieve the objectives.

This study reveals that the redenomination risk connectedness throughout the Euro area sovereign bond markets is dynamic and exhibits remarkable variations across various crisis episodes, such as the COVID-19 pandemic and Russia–Ukraine tensions. In addition, the analysis uncovers significant bilateral connections between countries. Furthermore, the research finds that spillovers from the US dollar redenomination premium (USDRP) are greater than those from the euro redenomination premium (ERP) and currency redenomination premium (CRP). However, during the Ukraine–Russia tensions, the connectedness between the USDRP is stronger than that between the ERP and CRP. On the other hand, the connectedness between CRP is higher than the USDRP and ERP during the COVID-19 pandemic. Importantly, this study demonstrates that the four countries play a role as both shock transmitters and receivers, switching alternatively.

This study contributes to the related literature by exploring the redenomination risk connectedness throughout the Euro area sovereign bond markets. Specifically, we rely on the USDRP, the ERP and CRP. These findings have serious implications for both portfolio risk management.

The role of inventors' creativity is crucial for technological innovation within enterprises. The mobility of inventors among different enterprises is a primary source for companies to acquire external knowledge. The mechanism of “learning-by-hiring” is widely recognized by companies. Therefore, it is important to determine how to allocate network resources to enhance the creativity of inventors when companies hire mobile inventors.

The study suggests an analytical framework that analyzes alterations in tie strength and structural holes resulting from the network embeddedness of mobile inventors as well as the effect of the interaction between these two variables on changes in inventor’s creativity after the mobility. In addition, this paper examines the moderating impact of cognitive richness of mobile inventors and cognitive distance between mobile inventors and new employers on the correlation between network embeddedness and creativity.

This study found that: (1) The increase of tie strength has a significant boost in creativity. (2) Increasing structural holes can significantly improve the creativity of mobile inventors. (3) When both the tie strength and the structural holes increase, the creativity of the mobile inventors significantly increases. (4) It is important to note that when there is a greater cognitive distance, stronger tie strength promotes the creativity of mobile inventors. Additionally, cognitive richness plays a significant role in moderating the relationship between changes in structural holes and the creativity of mobile inventors.

These findings provide theoretical guidance for firms to effectively manage mobile inventors and optimize collaborative networks within organizations.
