    Chinese urbanites and the preservation of rare species in remote parts of the country : the example of Eaglewood
    (2014) Pelz, Sonna; Langenberger, Gerhard; Frör, Oliver; Ahlheim, Michael
    Based on a Contingent Valuation study in Shanghai we assess peoples willingness to contribute personally to the alleviation of environmental problems occurring in distant parts of the country. One split of our survey assessed Shanghai residents willingness to pay for the preservation of rainforest in Yunnan, while the other split referred to the willingness to pay for the preservation of a single plant species (i.e. eaglewood) growing in this rainforest. The objectives of this study were twofold. Firstly, we wanted to find out if people living in big Chinese cities like Shanghai take an interest in the environmental problems existing in some remote parts of the country and if they are willing to contribute personally to remedy these problems. Secondly, we wanted to learn more about the motivation behind this kind of empathy, if it exists. We were especially interested in the question if this empathy refers to the specific environmental problems we addressed in our surveys or if it is motivated more by a general feeling of obligation towards environmental issues.

    Contingent valuation and money attitudes
    (2015) Pelz, Sonna; Ahlheim, Michael
    The Contingent Valuation Method (CVM) is one of the most frequently applied techniques to assess and monetise the benefits of environmental improvements. This survey-based method aims to elicit individuals’ willingness to pay (WTP) for enhanced environmental quality by means of hypothetical payment questions. Analysts interpret stated WTP as the monetary equivalent of the utility gain an individual expects to experience due to a specific environmental improvement. In spite of its frequent use, the validity of WTP statements is recurrently questioned and analysts have pointed to several sources of bias, such as a poor CVM survey design or certain characteristics of the respondents. This dissertation focuses on respondent characteristics which hitherto have not been examined, namely individuals’ attitudes towards spending money in general. The disposition of a person to spend money is expected to systematically affect and possibly bias stated WTP. While money attitudes have been extensively studied in psychological research, they have never been considered to be of influence in the context of environmental valuation. Given this lack of research, this dissertation investigates, theoretically and empirically, the role of money attitudes in CVM surveys.

    Varieties of knowledge-based bioeconomies
    (2014) Pyka, Andreas; Urmetzer, Sophie
    Governments around the world seek for strategies to overcome the reliance on fossil resources and provide solutions for the most challenging contemporary global issues: food shortage, depletion of natural resources, environmental degradation and climate change. A very recent and widely diffused proposition is to transform economic systems into bio-based economies, which are based on new ways of intelligent and efficient use of biological re-sources and processes. If taken seriously, such endeavour calls for the creation and diffusion of new knowledge as basis for innovation and behavioural change on various levels and therefore often is referred to as knowledge-based bioeconomy. In the current debate, the requirement for innovation is mostly seen in the advance of the biotechnology sector. How-ever, in order to fulfil the requirement of sustainability, which implicitly is connected with the bio-based economy, the transformation towards a bioeconomy requires a fundamental socio-economic transition and must comprise changes in technology as well as in markets, user practices, policy, culture and institutions. To illustrate a nation’s capability for this transition, we refer to the concept of national innovation systems in its broad approach. With the help of an indicator-based multivariate analysis we detect similarities and dissimilarities of different national systems within the European Union as basis for a transition towards a knowledge-based bioeconomy. The analysis allows to compare the different strategies and to identify bottlenecks as well as success factors and promising approaches in order to design policy instruments to foster this imperative transformation.
