| A variety of questioning formats have been used in contingent-valuation studies, with dichotomous-choice questions becoming the preferred format. However, as with any empirical technique, continued applications raise questions that require attention if the credibility of the procedure is to be maintained. It is shown that estimated Hicksian surplus can be substantially affected by the selection of a functional form when analyzing responses to dichotomous-choice questions. Given that theory, intuition, and empiricism all play a role in developing these estimates, several maxims are suggested for evaluating and/or mitigating such effects in future studies. |

| Contingent-valuation estimates for white-water boating passengers are compared with Likert ratings by river guides. The approach involves asking whether passengers and their guides ordinally rank alternative flows the same. The National Oceanic and Atmospheric Administration's Contingent Valuation Panel (1993) suggested "one might want to compare its (contingent-valuation's) outcome with that provided by a panel of experts." River guides constitute a counterfactual panel of "experts." For commercial trips, optimum flows are 34,000 cfs and 31,000 cfs for passengers and guides, and the comparable figures for private trips are 28,000 cfs and 29,000 cfs. In the NOAA Panel framework, passengers can evaluate the consequences of various river flows and... |

| Policy makers often face the problem of evaluating how water quality affects a region's economic well-being. Using water clarity as a measure of the degree of eutrophication levels (as a lake becomes inundated with nutrients, water clarity decreases markedly), analysis is performed on sales data collected over a six-year period. Our results indicate that water clarity has a significant effect on prices paid for residential properties. Effects of a one-meter change in clarity on property value are also estimated for an average lake in four real estate market areas in New Hampshire, with effects differing substantially by area. Our findings provide state and local policy makers a measure of the cost of water quality degradation as measured by changes in... |

| Choice modelling is increasingly being used to generate estimates of the value of changes in environmental quality. This is partly because of the informational efficiencies of the technique, but also because of concern about the accuracy of contingent valuation. Experimental evidence has, however, demonstrated that choice modelling tends to produce much higher valuation estimates than contingent valuation. One possible explanation for the divergence between choice modelling and contingent valuation estimates is the lack of incentive compatibility with the former technique. This potentially has several sources, including having no provision rule (eg a referendum), respondents choosing between more than two alternatives, and repeated choices. We report on... |

| Contingent valuation is used to measure the benefits of a proposed public program to control black flies. Respondents' reported values are analyzed from three perspectives: data outliners, consistency between respondents' reported values and their perceptions of black flies, and the temporal reliability of the values expressed by respondents. The results suggest that the estimated contingent values are plausible even though a majority of respondents expressed a value of zero dollars for the black fly control program. |

| Deterministic rules for generating choice sets are often employed by analysts confronting universal sets with large numbers of alternatives. For destination choice analysis, site exclusion rules defined by travel time, distance, or quality have a behavioral appeal, yet are fundamentally limited by their one-dimension scope. To remedy this shortcoming while maintaining the concept that trips require costly inputs to yield utility generating outputs, we develop and test an exclusion rule for generating choice sets defined by efficiency measures derived from stochastic frontier econometric models. Choice set composition, site choice efficiency and probability of selection, and consumer surplus are compared with results obtained under alternative exclusion... |
