RT Journal Article SR Electronic T1 Are Mobile Device Location Data a Substitute for Travel Cost Surveys? JF Land Economics FD University of Wisconsin Press SP 400 OP 417 DO 10.3368/le.102.3.012626-0015 VO 102 IS 3 A1 Bayham, Jude A1 Enriquez, Aaron J. A1 Richardson, Leslie YR 2026 UL http://le.uwpress.org/content/102/3/400.abstract AB Mobile device location data offer a low-cost alternative for measuring visitation to outdoor recreation sites and are known to correlate with official visitation counts. Less is known about whether these data can recover recreation demand and consumer surplus comparable to survey-based methods. We compare travel cost models estimated using mobile device and survey data for 17 US National Park Service sites. Results are mixed. We examine the roles of aggregation and sampling bias and use a LASSO regression to assess whether sample and site characteristics explain discrepancies.
