The main objective of this paper is to provide additional empirical evidence of what explains respondent uncertainty in contingent valuation (CV) and how this in turn affects stated willingness to pay (WTP). Air travelers asked to pay a carbon travel tax to offset carbon emissions from flying...

Integrated hydro-economic models aim to capture the complexity of interactions between water and the economy. Three main approaches are distinguished: modular, holistic and computable general equilibrium models. The latter top-down models counterbalance the traditional emphasis on bottom-up...

While meta-analysis is typically used to identify value estimates for benefit transfer, applications also provide insights into the potential influence of design, study and methodological factors on results of non-market valuation experiments. In this paper, a metaanalysis of sixteen separate...

Metrics for evaluating environmental trade-offs can be developed with varying levels of consistency across case study sites. A key issue is whether standard evaluation experiments can be conducted over multiple sites, or whether experiments have to be tailored to each case study application. To...

Improving existing drinking water supply services in developing countries depends crucially on available financial resources. Cost recovery rates of these services are typically low, while demand for more reliable services is high and rapidly growing. Most stated preference-based demand studies...
