Partizipative Szenarioverfahren werden vielfach in der Nachhaltigkeitsforschung angewendet. Zu den Vorteilen zählen: Praxiswissen macht die Zukunftsbilder robuster, strategisches Denken wird gefördert, ein kreativer Diskussionsrahmen entsteht. Nur wie werden narrative Szenarien im transdisziplinären Kontext entwickelt?
Die vorliegende Arbeit versteht sich als differenzierte methodische Beschreibung. Der Erfahrungsbericht legt am Beispiel des BMBF-Forschungsprojektes „SAUBER+: Innovative Konzepte und Technologien für die separate Behandlung von Abwasser aus Einrichtungen des Gesundheitswesens“ die einzelnen Arbeitsschritte der Szenarioentwicklung offen und diskutiert ihren Stellenwert. Die Vorgehensweise im Projekt wird kritisch reflektiert; daraus werden Hinweise für die Verwendung partizipativer Szenarien in anderen Forschungsprojekten abgeleitet.
This paper investigates risk-taking in the liquid portfolios held by a large panel of Swedish twins. We document that the portfolio share invested in risky assets is an increasing and concave function of financial wealth, leading to different risk sensitivities across investors. Human capital, which we estimate directly from individual labor income, also drives risk-taking positively, while internal habit and expenditure commitments tend to reduce it. Our micro findings lend strong support to decreasing relative risk aversion and habit formation preferences. Furthermore, heterogeneous risk sensitivities across investors help reconcile individual preferences with representative-agent models.
It is often claimed that decentralisation is effective for the reduction of poverty due to inherent opportunities for higher popular participation and increased efficiency in public service delivery. This paper is a qualitative assessment of the potential of the Ugandan decentralisation reform for poverty alleviation. The Ugandan government initiated an ambitious decentralisation reform in 1992, which represents an example of full-fledged devolution with the transfer of far-reaching responsibilities to local governments. However, several shortcomings, such as low levels of accountability, insufficient human and financial resources, corruption, patronage, and central resistance to decentralisation, constrain the proper implementation of the reform, putting improvements in participation and efficiency at risk and ultimately jeopardising the intended impact on poverty.
