Valuing Offshore Habitat to Recreational Anglers Using Cellphone Location Data
研究结合随机效用模型与手机定位数据，评估墨西哥湾西部近海结构（如能源平台）对休闲垂钓者的非市场价值，发现垂钓者偏好有运营或人工礁平台的远海目的地。
<h3>Abstract</h3> Offshore structures, including operational and reefed energy platforms, strengthen marine habitats and generate economic value, motivating interest in quantifying their net benefits. We combine a Random Utility Model with Murdock9s (2006) site-choice approach to estimate the nonmarket value of offshore structures to recreational anglers in the Western Gulf of Mexicoi (2019-2022). Recreational fishing trips are identified in cellphone location data using a machine learning classifier trained on Automatic Identification System data. Location choices indicate that anglers value destinations farther offshore, particularly those with operating and reefed energy platforms, while other artificial reefs generate smaller and spatially variable benefits.
