“…The application of WTP in tourism research has mainly focused on determining the amount of WTP and the factors driving the paying preference or amount (e.g., Chen, Zhang, & Nijkamp, 2016) in various contexts, including natural attractions such as natural parks and rainforests (e.g., Reynisdottir, Song, & Agrusa, 2008), outdoor recreation activities (Asafu-Adjaye & Tapsuwan, 2008), natural resource management and conservation (e.g., Piriyapada & Wang, 2015) and green tourism products (Hinnen, Hille, & Wittmer, 2015). These studies have identified a series of WTP determinants in different contexts and mapped the demand curve and elasticity patterns based on WTP values.…”
