This report presents summary statistics and other results of a survey of Clear Lake visitors and residents. Drawing on survey results, the authors present information on recreational usage of the lake, attitudes of recreators and local residents toward possible watershed management changes, and...

Understanding how Iowans view the benefits and costs of wetlands preservation is key to making decisions about the future of wetlands in Iowa. To that end, the authors created "The Iowa Wetlands Survey." How the survey was designed and administered is described and the results are summarized....

The authors model the recreation demand for Iowa wetlands, combining survey data on both actual usage patterns (i.e., revealed preferences) and anticipated changes to those patterns under hypothetical increases in trip costs (i.e., stated preferences). They formulate and test specific hypotheses...

A new approach is under way for the research agenda of environmental valuation. Rather than treating stated preference (SP) and revealed preference (RP) as competing valuation techniques, analysts have started to view them as complementary, where the strengths of each approach can be used to...

Manski [13] proposed an approach for dealing with a particular form respondentuncertainty in discrete choice settings, particularly relevant in survey based researchwhen the uncertainty stems from the incomplete description of the choice scenarios.Specically, he suggests eliciting choice...

Recreation demand models typically incorporate measures of the physical attributes of recreational sites; e.g., Secchi depth or phosphorous levels in case of water quality. Moreover, most studies show that individuals do respond to these physical characteristics in choosing where to recreate....

A new turn in the research agenda of environmental valuation is under way. Rather than treating stated preference (SP) and revealed preference (RP) as competing valuation techniques, analysts have begun to view them as complementary, where the strengths of each approach can be used to provide...

The focal point of the revealed preference (RP) valuation literature, including recreation demand and random utility maximization (RUM) models, has been on eliciting the “use” value associated with environmental amenities; i.e., that portion of value associated with direct use of a resource....

This paper examines the potential for combining revealed and stated preference data on Iowa wetland usage, employing a flexible functional form representation of site-specific utility. We examine a variety of hypothesis tests regarding potential sources for inconsistency between stated and...

The Kuhn-Tucker model of Wales and Woodland (1983) provides a utility theoretic framework for estimating preferences over commodities for which individuals choose not to consume one or more of the goods. Due to the complexity of the model, however, there have been few applications in the...
