We report on a discrete-choice CV study conducted in Germany to value the WTP for biodiversity protection in less developed countries. To systematically investigate survey realism and subjective threat assessment from the loss of biodiversity described in the scenario the study includes questions to uncover the constructs of Protection Motivation Theory, which is introduced to the CV literature. The patterns of responses to such questions are analysed using an Expectation-Maximization algorithm to derive class membership probabilities. These are found to match the predictions of Protection Motivation Theory and systematically improve the logistic analysis of the WTP responses. Terms of use: Documents in

Assessing cultural values: developing an attitudinal scale

“…Clusters with a small number of members were avoided because of potential outliers. 31 For example, see Morey et al (2006), Scarpa and Menzel (2005) and Winter et al (2003). 32 For example, see Ben-Akiva et al (1999), andVredin Johansson et al (2006).…”

Cultural Attitudes as WTP Determinants: A Revised Cultural Worldview Scale

“…When attitudinal characteristics of respondents are incorporated into economic models as unobserved factors they are normally employed as explanatory variables [5,8,29] or as segmentation criteria for cluster analysis [30][31][32]. Some studies that have applied systematic measurement scales have shown mixed empirical findings for the attitude-WTP association [3,4,6,33].…”
