Towards a Better Understanding of Entrepreneurial Teams: Investigating Temporal Dynamics on Multiple Levels
(2023)
This dissertation investigates entrepreneurial teams in the process of creating new ventures. The new venture creation process is complex. Different actors impact the new venture creation process in various ways, either facilitating or complicating it. The three studies at the heart of this thesis aim to cut through this complexity by examining the social context (i.e., entrepreneurial teams) and the temporal dynamics occurring in more detail. All studies address the conditions underpinning entrepreneurial teamwork ...

Analysis on Successful Project Completion in Reward-based Crowdfunding
(2023-10)

Previous literature has shown researcher mobility to be an important driver of knowledge diffusion and, subsequently, the creation of new knowledge. However, different mobility types are often correlated and hard to differentiate. This thesis tries to help advance this research strand, in ...

A systematic literature review exploring uncertainty management and sustainability outcomes in circular supply chains
(2021)
The circular economy (CE) has inspired the emergence of circular supply chains (CSCs) to reduce the environmental impacts of linear production systems. However, the transition to CSCs faces numerous challenges and uncertainties, which in turn impact the sustainability performance of CSCs. Following a systematic review process, this paper aims to identify the uncertainties that CSCs entail and the uncertainty management strategies which can be used to mitigate them to enhance their sustainability performance. A ...

Quantitative analysis of the Interbank credit market e-MID in the high frequency domain
(2020)
Interbankenkreditmärkte, und vor allem das ungesicherte übernacht-Segment, gelten aus verschiedenen Blickwinkeln als wichtig für das gesamte Finanzsystem.

Distorsionen in der Liquiditätsbeschaffung haben dabei negative Auswirkungen auch auf der mikroökonomischen Ebene, da diese die Kreditkonditi-onen von Haushalten und Firmen beeinflussen. Da Interbankenkreditmärkte als der erste ...
