This article conceptualizes the vulnerability of the different stages of Public-Private Partner-ship (PPP) models for corruption against the backdrop of contract theory, principal-agent theory and transaction cost economics, and discusses potential control mechanisms.
The article’s contribution to the debate on PPPs is twofold: first, an issue widely neglected by the pertinent literature is conceptualized. Second, as these PPPs are used not only in de-veloped countries whose legal order may shield them sufficiently, but also in developing countries, carving out the vulnerable points in PPP arrangements may enable decision mak-ers to install appropriate control mechanisms, if need be on project level.
National innovativeness is one key driver of economic development. The relation of national innovativeness and national culture has been firmly established by research. Cultural factors, however, influence national innovativeness via different mechanisms on the macro-, meso-, and micro-level of a country. In our paper, we build on existing research on the link between cultural dimensions and national innovativeness to develop a new model that classifies different cultural dimensions in groups according to their mechanism: political, social, or individual (PSI-model). Using a newly-established data set composed of world data, we test and find support for this model using a variety of regression models. The PSI-model provides a more structured theoretical background of the impact of different cultural dimensions on national innovativeness, especially with regard to social practices and social values. It can be used to generate policy recommendations on national innovativeness and offers further applications in fields related to the various impacts of national culture.
The links between innovativeness as a driver of economic performance, and the determi-nants of innovativeness have been investigated by management scholars and economists
for decades, focusing mostly on “hard factors” as investment in research and development, or education. Focusing on a relatively neglected, but in times of globalization even more important aspect, the influence of cultural characteristics on innovativeness, we apply different econometric models to test for links between cultural tightness and looseness on the one hand, and national innovativeness on the other hand. We find that cultural tightness — in the sense of homogenous and intolerant societies — has a negative link to national innovativeness, while cultural looseness — in the sense of tolerant and diverse societies — displays a positive link to national innovativeness.
The link between economic development, entrepreneurial activity, and institutional frame-work conditions has been focused by scholars from different disciplines, inter alia economics and business management, and is of utmost relevance also for practitioners. This applies in particular to the question of those macro factors that exert an influence on the sustainable success of entrepreneurial activity.
PESTEL analysis as a strategic tool that focuses on the assessment of the business environ-ment in terms of specific market conditions, (likely) developments and their positive or negative effects on an enterprise is a popular instrument in this context. However, the existing literature often offers only a compilation and partial discussion of categories and dimensions, but does not include a discussion of the effects of specific framework conditions in detail, nor provides concrete indicators to make the concept operable. The article deals with this question, providing an operationalization of numerous sub-categories of PESTEL, as well as discussing possible extensions to the PESTEL toolbox that become necessary against the backdrop of globalization and digitization.
Das Projekt HoWas20211 untersucht die Bewältigung der Starkregen- und Hochwasserereig-nisse im Juli 2021 in Nordrhein-Westfalen und Rheinland-Pfalz. Durch die Zusammenarbeit verschiedener Fachdisziplinen (Hydrologie/Meteorologie, Kommunikationswissenschaft, Ver-waltungswissenschaft, geographische Risikoforschung und sozialwissenschaftliche Katastro-phenforschung) gelang es in dem Projekt, eine differenzierte Beschreibung der Ereignisse insbesondere bezogen auf Schwachstellen in der Governance und Kommunikation vorzu-nehmen.
Zwei Jahre nach dem intensiven Hochwasserereignis im Juli 2021 liegen erste Erkenntnisse
im Rahmen der wissenschaftlichen Aufarbeitung vor. Das BMBF-HoWas2021-Projekt richtet hierbei seinen Fokus auf die Warnkommunikation und das Krisenmanagement. Die Analyse beinhaltet die Verknüpfung vonmeteorologischen und hydrologischen Daten mit Aktivitäten aufbehördlicher Ebene und dem Katastrophenschutz. Im Ergebnis können technische und strukturelle Optimierungspotenziale identifiziert werden und deuten somit auf den Nachhol-bedarf bei der Antizipation zukünftiger Hochwasser und dem Entwickeln neuer Ansätze für effektive Warnsysteme hin.
