ABSTRACT
Discrete choice revealed and stated preference data can be used to elicit information about participation in an activity or market. Revealed and stated preference frequency data can be used to elicit information about the intensity of consumption of environmental-related goods and services such as recreation trips and seafood meals, among a number of other possibilities. One limitation of the revealed preference data arises over measurement of environmental values when environmental conditions change. For example, improvements in environmental quality might lead to a shift of the recreation demand curve. Stated preference data can be used to better estimate the demand shifts and resulting changes in environmental values. In these situations stated preference data is typically layered into (i.e. stacked with) revealed preference data and standard econometric models can be used.
