Document Summary
Hypothetical -> attribute-based models: conjoint analysis, choice experiments, contingent ranking. Putting a value on non-use -> spotted owl eg. contingent valuation: survey asking people to value environmental change. Respondents try to influence results: eg. May overestimate value of fishing along a river they enjoy. Respondents have little to no experience with environmental parameter: eg. Compare recreation on two different lakes: starting-point bias. Pre-defined range of possibilities: hypothetical bias. Respondents may not ever have to pay anything. Use the amount currently paid to travel to the lake to construct the demand curve for willingness to pay. Analyze site characteristics and importance to visitors. Immoral-> all people have the right to live: counter argument: immoral not to consider the benefits of life saving measures. Removal of lead would no pass cost/benefit analysis. Hydro dam near grand canyon: didn"t build because of non-use value: showed positive net benefit because equivalent power from thermal plant was too expensive.
