Última Iowa Wetlands: Perceptions and Values AgEcon Azevedo, Christopher D.; Herriges, Joseph A.; Kling, Catherine L.. With major funding from the U.S. Environmental Protection Agency, researchers at Iowa State University developed and administered a survey of Iowans' usage and attitudes concerning wetlands. This report summarizes some of the primary findings from the survey. Tipo: Working or Discussion Paper Palavras-chave: Wetlands; Economic valuations; Recreation demand; Land Economics/Use. Ano: 2000 URL: http://purl.umn.edu/18672 Linking Revealed and Stated Preferences to Test External Validity AgEcon Herriges, Joseph A.; Kling, Catherine L.; Azevedo, Christopher D.. 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 more precise and possibly more accurate benefit estimates. In this paper, we reexamine the models and motives for combining revealed and stated preference data. First, we note that because the different kinds of SP data contain different amounts of information, they may indicate different degrees of consistency with RP data. We also reconsider the interpretation of "consistent" or "inconsistent" findings of RP and SP data. We argue that while the conventional approach...

Ano: 1999 URL: http://purl.umn.edu/18602 LINKING REVEALED AND STATED PREFERENCES TO TEST EXTERNAL VALIDITY AgEcon Herriges, Joseph A.; Kling, Catherine L.; Azevedo, Christopher D.. 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 revealed preferences, including the form of the state preference questions themselves.

Ano: 1999 URL: http://purl.umn.edu/21555 Ask a Hypothetical Question, Get a Valuable Answer? AgEcon Azevedo, Christopher D.; Herriges, Joseph A.; Kling, Catherine L.. This paper models 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). We formulate and test specific hypotheses concerning potential sources of bias in each data type. We consistently reject consistency between the two data sources, both in terms of implied wetland values and underlying preference parameters. Careful attention is paid to the interpretations of the test results, noting particularly how the interpretation of the same results can vary with the "school of thought" of the reader.
