South Korean coastal wetlands are known as one of the five most important wetlands in the world. This research, addresses some controversial issues relating to the nonuse values of the wetlands, and applies a contingent valuation (CV) method to estimate the conservation or nonuse values of the coastal areas around Youngsan River in Korea.
The CV survey used a double-bounded dichotomous choice(DBDC) format and was conducted for 1,000 households in Seoul. The conservation values were estimated based on Hanemans model and Kristrom`s spike model using the maximum likelihood method. In addition, spike model was expanded from single-bounded dichotomous choice data to DBDC-CV data. This is the main contribution of this study to the empirical research in this field. An estimate of the annual aggregated conservation value of the coastal wetlands for entire Korean households approximates 175,745 million won (US$175.7 million). On the other hand, cost-benefit analysis (CBA) related to the Korean wetland development was conducted to identify how much the nonuse value affects the result of CBA. An extended CBA reflecting the estimated nonuse values resulted in an IRR that is about 30% lower than that of conventional CBA, implying CBA can be heavily affected by nonuse values. A goal-seeking model was used to evaluate the economic feasibility of wetland preservation and development based on the magnitude of nonuse values. The result shows that the wetland development project can be rejected if the annual nonuse value for wetland is 3,000 won per Korean household for the first five years. Therefore, a more broadly defined economic value of coastal wetlands may lead to different policy decisions. |
