The European payment market has undergone rapid transformation in recent years due to changes in payment habits, new business rules and new legal frameworks and regulation. There has also been an advent of new technologies and payment solutions which has altered the European payments landscape drastically. This book provides an overview of the fundamental issues involved in this new payments landscape. The authors discuss fundamental problems such as substitution between cash and non-cash payment instruments, payment costs, the economics of fees, and the demand for cash and deposit money. They also analyse issues such as two-sided markets, business platforms and the problem of critical mass. Other chapters focus on new phenomena in payments such as mobile payments, multi-sided platforms, electronic wallets, virtual currencies, decentralised ledgers, private digital currencies, blockchain and instant payments. The authors also review existing regulation for the topic including the revised Payment Services Directive (PSD2), Interchange Fee Regulation (IF/MIF Reg), and the Single Euro Payments Area (SEPA) project. Transforming Payment Systems in Europe offers insight into changing payment culture and the ways in which new payment systems can create a single digital market to foster further integration in Europe.

In the context of the advancing digitalization of logistics processes, blockchain technologies are gaining in importance. Within the scope of sustainable logistics networks, they contribute to cross-stakeholder transparency and support the tracking and verification of products and processes to improve social and environmental parameters. The goal of this work is to develop a holistic management model to help users understand blockchain technologies in the context of their logistics network and to assess the mindful adoption of these technologies to specific problems. In addition, the model should enable the conclusion of expected impacts on participating actors within the logistics network with regard to social and environmental sustainability and, in a further step, provide a holistic approach to the implementation of blockchain technologies. Methodologically, a systematic literature analysis, two workshops and a case study exploration will be conducted for this purpose. Within the systematic literature analysis, 285 articles are evaluated and 53 relevant articles are synthesized. Based on the Nominal Group Technique, a first workshop with 30 experts from manufacturing companies, logistics service providers, technology companies and universities will be conducted and supplemented by a subsequent survey. In a second workshop, three use cases of blockchain technologies are analyzed with 24 experts in open and moderated group discussions. Finally, three exemplary case studies and eight expert interviews are conducted and systematically evaluated with respect to cross-case findings. The result of this thesis is a four-phase management model that guides users through the process of evaluating and implementing blockchain technologies in the context of sustainable logistics. While the first phase assesses requirements of the logistics network for general applicability of blockchain technologies, the second phase includes a model for the mindful adoption of blockchain technologies. Based on this, phase three provides a sustainability impact model to explain social and environmental impacts of individual actors involved in the logistics network. The fourth phase ultimately represents the implementation of blockchain technologies in logistics and is based on five management areas in which specific design recommendations, methods and tools are provided to enable a successful implementation. Finally, the thesis provides an outlook on a future vision and shows which changes in logistics networks can be expected due to blockchain technologies.
