The impact of wildfires on the recreational value of heathland: A discrete factor approach with adjustment for on-site sampling
扩展了有限混合模型以控制现场抽样偏差，应用于欧洲保护区灌木丛地的休闲需求数据，首次估计了野火对该地休闲价值的影响，发现抽样校正对福利测度无显著影响。
This study extends the finite mixture model proposed by Landry and Liu (2009) to control for on-site sampling in the context of a system of recreation demand equations. We apply the model to a quasi-panel of recreational trip data under current and hypothetical wildfire conditions. We use the estimated model to provide the first estimate of recreational value for heathland in a European protected area and for how wildfires affect this value. Although we find statistical support for our proposed on-site sampling correction, we find that the correction generates no significant impact on welfare measures in our application.
