Combining choice experiments with psychometric scales to assess: a latent class approach / Strazzera, Elisabetta; Mura, Marina; Contu, Davide   Journal Article
Strazzera, Elisabetta Journal Article
0 Rating(s) & 0 Review(s)
Publication 2012.
Summary/Abstract A choice experiment exercise is combined with psychometric scales in order: (1) to identify factors that explain support/opposition toward a wind energy development project; and (2) to assess (monetary) trade-offs between attributes of the project. A Latent Class estimator is fitted to the data, and different utility parameters are estimated, conditional on class allocation. It is found that the probability of class membership depends on specific psychometric variables. Visual impacts on valued sites are an important factor of opposition toward a project, and this effect is magnified when identity values are attached to the specific site, so much that no trade-off would be acceptable for a class of individuals characterized by strong place attachment. Conversely, other classes of individuals are willing to accept compensations, in form of private and/or public benefits. The distribution of benefits in the territory, and preservation of the option value related to the possible development of an archeological site, are important for a class of individuals concerned with the sustainability of the local economy.

Complementing choice experiment with contingent valuation data: Individual preferences and views towards IV generation nuclear energy in the UK / Contu, Davide   Journal Article
Contu, Davide Journal Article
0 Rating(s) & 0 Review(s)
Summary/Abstract Nuclear energy represents an essential component of the energy mix in the United Kingdom (UK). While most of the existing nuclear plants are scheduled to be decommissioned, new reactors are in the process of being built. Looking ahead, IV generation nuclear energy technology, that aims to minimize some of the hazards of current technologies, is under research and development (R&D). This paper investigates social acceptance of IV generation nuclear energy, examining both willingness to accept (WTA) new nuclear power plants and willingness to pay (WTP) for further research of IV generation technology. Choice experiments (CE) were employed to assess WTA, while contingent valuation (CV) was used to unveil WTP. Results revealed the presence of four segments of respondents: moderate supporters, strong opposers, and two groups of moderate opposers of new nuclear power plants. Interestingly, even amongst strong opposers there are individuals willing to pay for R&D of IV generation technology. Policies aimed at fostering trust – if deserved – towards nuclear energy corporations and authorities, as well as showing tangible progress of R&D to raise confidence among the public are key to foster acceptance of this nuclear energy technology.
