| Outline of Final Research Achievements |
In this study, willingness to pay (WTP) of the general public for the marine ecosystem conservation was estimated by using best-worst scaling (BWS). Our results show people evaluate the conservation of the endangered species higher than increasing catch or recreation sites. The estimation results of the latent class model using the EM algorithm show the preference for increasing recreation sites is more heterogeneous among people than that for the conservation of the endangered species and increasing catch. In addition, it becomes clear that BWS is useful method to estimate WTP compared to other stated preference method including choice experiment and contingent ranking.
