Labour as a utility measure reconsidered
(2017) Pham, Van Dinh; Ahlheim, Michael; Frör, Oliver; Nguyen, Minh Duc; Rehl, Antonia; Siepmann, Ute
In Stated Preference studies for the appraisal of environmental projects in poor countries or regions it often turns out that the stated willingness to pay of people for environmental improvements, which is used as measure of individual welfare changes, is very low. This is often interpreted as the result of extremely tight budget constraints, which make it impossible that people express their true appreciation of an environmental project in terms of their willingness to pay for it. Therefore, it is sometimes suggested to use labour contributions instead of money as a numeraire to measure utility in such studies. In this paper we show theoretically and empirically that this suggestion is not compatible with the principles of welfare theory because of several inconsistencies. We also illustrate the validity of our arguments empirically based on the results of a Contingent Valuation study conducted in a rural area in northern Vietnam.
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.
The return of happiness : resilience in times of pandemic
(2022) Ahlheim, Michael; Kim, In Woo; Vuong, Duy Thanh
Many papers have been written about peoples loss of life satisfaction during the first wave of the COVID-19 pandemic in 2020, but not much has been said about their resilience after the first shock had passed. Were people able to return, at least in part, to their original level of life satisfaction? This amounts to the question to which degree people had shown psychological resilience during the first wave of the COVID-19 crisis. In this context, it is also of interest which internal and external factors supported a persons tendency to prove resilient during the crisis. Based on an online survey conducted in August / September 2020 in Germany we try to answer these questions. We find that after a loss of average life satisfaction during the first three months after the outbreak of the pandemic in Germany many peoples life satisfaction increased again. Roughly 60% of the respondents proved resilient in the sense that eight months after the outbreak of the pandemic they had regained the same or an even higher level of life satisfaction as compared to the situation before the COVID-19 crisis. Our results show that besides socioeconomic characteristics like age and income and certain character traits, peoples personal experience during the crisis and their approval or disapproval of government policy during the crisis had an important influence on their chance to prove resilient. Therefore, a consistent and competent crisis communication building up trust in governments crisis management capacity is essential for peoples resilience in a crisis.
Wasted! Resource recovery and waste management in Cuba
(2018) Trastl, Heike; Ahlheim, Michael; Becker, Maike; Allegue Losada, Yeniley
The collection of solid waste and the recovery of recyclable material from waste belong to the many challenges Cuba has been facing over the past years. In this paper, we give a short account of the actual waste situation and analyze the causes of the obvious deficiencies of the waste sector. We conducted a small survey in Havana city in order to assess peoples awareness of the garbage problem, their appraisal of the actual situation and their willingness to contribute personally to an improvement of the waste situation. Based on the insights gained from this survey and from our theoretical analysis of the Cuban waste management we develop suggestions for an improvement of the waste situation in Cuba. These suggestions take into account that the financial means available for a reform of the waste management system in Cuba are severely restricted. Therefore, our suggestions are more focused on organizational and motivational changes than on the introduction of high technology.
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.
