    Labour as a utility measure in contingent valuation studies : how good is it really?
    (2010) Ahlheim, Michael; Frör, Oliver; Heinke, Antonia; Duc, Nguyen Minh; Van Dinh, Pham
    The Contingent Valuation Method (CVM) aims at the assessment of people's willingness to pay (WTP) for a public project. The sum of the individual WTPs is interpreted as the social benefits of the project under consideration and compared to the project costs. If the benefits exceed the costs the project is recommended for realization. In very poor societies budgets are so tight that households cannot give up any part of their income, i.e. of their market consumption, in favour of a public project, so that their WTP for that project stated in a CVM interview has to be zero or close to zero. This leads to a severe discrimination against poor regions in the decision process on the allocation of public funds. Therefore, several authors suggest to use labour contributions to the realization of a public project instead of monetary contributions as a measure of people's WTP for that project. In this paper we show theoretically and empirically, based on a CVM study conducted in Vietnam, that labour is severely flawed as a measuring rod for individual utility so that CVM based on labour contributions does not provide a reliable and meaningful decision rule for the allocation of public projects.

    Landslides in mountainous regions of Northern Vietnam : causes, protection strategies and the assessment of economic losses
    (2008) Zeller, Manfred; Saint-Macary, Camille; Pham, Van Dinh; Nguyen, Minh Duc; Keil, Alwin; Heinke, Antonia; Frör, Oliver; Ahlheim, Michael
    Landslides are a severe problem during the rainy season in many mountainous regions in Asia where forests have been cut so that mountain slopes are destabilized. In this study we analyze the extent and causes of landslides in a mountainous area in Northern Vietnam as viewed from the perspective of the concerned population. We also scrutinize the ideas of these people regarding suitable landslide protection measures and their willingness to contribute to the practical implementation of these measures. It shows that nearly all people living in this area feel highly concerned about the frequent landslide events and that they support the idea of government programs to mitigate the danger of future landslides. We measure the utility they expect from such a landslide protection program, i. e. the social value of such a program, in terms of their willingness to contribute personally to its implementation. Since budgets are tight in these rural areas where subsistence farming still prevails we also analyze the possibilities to measure these expected utility gains in terms of people's willingness to contribute working time instead of money to the proposed landslide protection program. The prospect of employing such an alternative means of contribution is, however, seen rather critical.
