The spatial limits of the travel cost recreational demand model.

Describes a method for judging the spatial limits of travel cost recreational demand models as they are contentionally applied to secondary data sets. Section II discusses a proposed test for defining the spatial limits of the travel cost model. It is a test designed for use in time series applications, but can readily be adapted to conform to the cross-sectional framework of travel cost applications. We present an example of the test and discuss the potential impact for consumer surplus estimates of such spatial limitations to the model. The case study is the Ventana Wilderness Area in Northern California. -from Authors
