Non-trading behaviour in choice experiments
(2016) Neidhardt, Jan; Ahlheim, Michael
This paper addresses a methodological problem of choice experiments, namely the problem that respondents sometimes avoid the intellectual effort of thoroughly considering the trade-offs between different alternatives that are the essence of every choice experiment, and tick instead the next best alternative without the necessary deliberation. This kind of behaviour which is called "nontrading" in the respective literature calls into question the validity of choice experiments. In this paper, which is based on an online choice experiment concerned with consumer’s tastes for table grapes with 1,000 participants, we suggest possibilities to identify potential non-traders not only by their answering behaviour but also by some general characteristics we found to be typical of this kind of respondent.
Social capital from an individual perspective
(2018) Neidhardt, Jan; Ahlheim, Michael
Three contributions to the social capital literature are presented in this thesis: Firstly, a concept of social capital that is compatible with the individual perspective prominent in neoclassical economics is identified. Secondly, a new tool to measure individual social capital is developed and applied. Thirdly, results on the distributional effects of a great number of predictors on individual level social capital are obtained and discussed for a representative sample of the German resident population.
WeChat – using social media for the assessment of tourist preferences for environmental improvements in China
(2018) Yu, Xiaomin; Siepmann, Ute; Neidhardt, Jan; Ahlheim, Michael
Environmental valuation studies with tourists have been very popular already over a long period of time. Tourists are an important stakeholder group with respect to the decision if some environmental project in a tourist region should be realized or not. Typically such studies are organized as face-to-face surveys conducted in the respective vacation areas. Tourists are asked their willingness to pay (e.g. in terms of higher entrance fees for certain amenities on site or a mark-up on accommodation prices etc.) for the implementation of an environmental project or preservation measure in that area. Based on theoretical considerations we argue that in the special case of tourist surveys internet-based surveys are preferable to face-to-face surveys under validity aspects as well as under the aspect of the representativeness of the survey results. Based on an empirical valuation study we conducted in Southwest China we illustrate the practical problems arising in the context of internet surveys in developing or threshold countries.
