“…The results indicate that in the closer metropolitan area Berlin-Brandenburg people value changes in water quality positively. Results are therefore in line with studies from other countries (see [3,4,5,6,7]). The mean compensating variation measure for the metropolitan area results in an aggregated overall measure of around Mio € 420 per year for a good water quality in accordance with the EU-WFD objectives.…”

“…It was latter on suggested by researchers to employ economic valuation 34 when the need to define disproportional high measurement costs became evident (Brouwer [1]; 35 Hanley et al [2]). Meanwhile, several studies from across Europe determining the benefits of 36 changes in water quality have been presented, e.g., Bliem and Getzner [3]; Brouwer et al [4]; Glenk 37 et al [5]; Kataria et al [6], and Metcalfe et al [7]. 1 The studies, using the categorization of water 38 quality levels in the WFD, indicate that people value water quality improvements positively.…”

The value of water quality improvements in the region BerlinBrandenburg as a function of distance and state residency Meyerhoff, J., Boeri, M., & Hartje, V. (2014) The value of water quality improvements in the rivers of the metropolitan region Berlin-1 Brandenburg as a function of distance and state residency 2Abstract: The study uses a discrete choice experiment (DCE) to elicit willingness to pay estimates for 3 changes in the water quality of five river stretches. As many regions the metropolitan region Berlin-4Brandenburg struggles to achieve the objectives of the Water Framework Directive until 2015. A 5 major problem is the high load of nutrients. As the region is part of two states (Länder) and the river 6 sections are common throughout the whole region we account for the spatial context twofold. Firstly, 7we incorporate the distance between each respondent and all river stretches in all MNL and RPL 8 models, and, secondly, we consider whether respondents reside in the state of Berlin or Brandenburg. 9The compensating variation (CV) calculated for various scenarios shows that overall people would 10 significantly benefit from improved water quality. The CV measures, however, also reveal that not 11 considering the spatial context would result in severely biased welfare measures. While the distance-12 decay effect lowers CV state residency is connected to the frequency of status quo choices and not 13 accounting for residency would underestimate possible welfare gains in one state. Another finding is 14 that the extent of the market varies with respect to attributes (river stretches) and attribute levels (water 15 quality levels). 16

Plausible responsiveness to scope in contingent valuation

Plausible responsiveness to scope is a question of economic significance, in addition to statistical significance, of the scope test in contingent valuation. We briefly review the history of the scope test in order to place the current issue in the context of the BP Deepwater Horizon oil spill. As a result of the review we gain insights into how the issue of scope "adequacy" arose twenty years after it was first mentioned by the NOAA Panel on Contingent Valuation following the Exxon Valdez oil spill. We then provide a review of Desvousges, Mathews and Train (2012) who promote the adding-up test to identify inadequate responsiveness to scope adequacy. The adding-up test is a test of the construct validity of the contingent valuation method but is flawed as a measure of economic significance. We propose scope elasticity of willingness-to-pay as a measure of economic significance. A simulation suggests a likely range of elasticity estimates given linear and quadratic functional forms for the willingness-to-pay function. In order to illustrate the ease of implementation of scope elasticity within the context of the standard scope test we calculate scope elasticity with willingness-to-pay estimates from several studies, describe two studies that directly estimate scope elasticity and estimate scope elasticity with primary data from two studies. All of these empirical estimates of scope elasticity fall within the range of scope elasticity suggested by the simulation. Scope elasticity provides a practical way forward, relative to the adding up test, on the issue of economic significance of scope effects. t r a c tPlausible responsiveness to scope is a question of economic significance, in addition to statistical significance, of the scope test in contingent valuation.

“…In the final survey, according to Day (1999), Bateman et al (2008) and Metcalfe et al (2012), who highlighted the effects of the order in which elicitation questions are presented on the respondents' WTP, the sample was split in two sub-samples to be able to test sensitivities to these effects. In the A typology of questionnaire, respondents were firstly asked to express their WTP for the "Giant hollies", and secondly for "all the monumental trees" safeguard projects; in the T questionnaires the order of presentation was inverted.…”

ABSTRACT:The paper deals with the evaluation of the existence value of monumental trees in a protected area. Financial resources to be destined for protection interventions have been decreasing more and more, with a high risk of losing this natural heritage. A Contingent Valuation Method (CVM) survey was carried out among the Madonie Park (Sicily, Italy) resident households to evaluate the existence value of monumental trees of the nature trail named "Piano Sempria-Piano Pomo", represented by a population of "Giant hollies" and by 7 other individual trees. These are the main results of the CVM survey: the overall response rate was 40%, individual average WTPs ( Willingness To Pay) were €12.37 for the protection of the holly population and €13.45 for all the monumental trees along the nature trail. The median WTPs were €2.00 and €5.00, respectively. The aggregate WTP estimates for the Park residents range from a minimum of €10,520.40 to a maximum amount of €83,479.37 depending upon the investigated resource and the statistics considered.
