In many environmental valuation applications standard sample sizes for choice modelling surveys are impractical to achieve. One can improve data quality using more in-depth surveys administered to fewer respondents. We report on a study using high quality rank-ordered data elicited with the...

Instream flows may be essential in protecting aquatic species that are threatened or endangered. An economic model of the optimal allocation of water under pure uncertainty is developed, with particular attention paid to the situation when a species characterized by critical depensation is...

While a number of validity tests exist for contingent valuation data, to date there are very few literature examples for contingent behavior (CB) data. The objective of this study is to test the validity of CB trip data for different levels of rock climbing access using data from surveys...
