한국의 점박이물범 보전가치 추정

Spotted seal have been decreased by fishing industry, development and polluted water. Recently, an increasing number of Koreans have been calling for the conservation of spotted seal. There are conflicts between the supporters and opponents for the plan of constructing the tidal power plant in Garorim Gulf. For solving these conflicts, policy-makers and the public require monetary information on the conservation value of spotted seal. This study attempts to measure the willingness to pay (WTP) for conservation value of spotted seal. To this end, we report the results from a contingent valuation (CV) survey. In particular, a one-and-one-half-bound dichotomous choice (OOHBDC) format is employed as a method of eliciting WTP response to enhance statistical efficiency and decrease response bias. Moreover, we apply the spike model to deal with zero WTP responses from the OOHBDC CV survey. A survey of 1,000 randomly selected households was implemented in the nation from June 28 to July 18, 2013. The respondents were asked in person-to-person interviews about how they would be willing to pay for the spotted seal conservation. Overall, respondents accepted the contingent market, and were willing to contribute a significant amount (1,817 won), on average, per household per year. The annual mean WTP based on the spike model with covariates is 1,786 won per household. It is similar to 1,817 won of the model without covariates. Thus, it is concluded that the conservation measures are not significantly changed by adding covariates. This is why we do not expand the sample WTP estimate for the model with covariates to the pupulation value here. Expanding the value to the nation gives us an aggregate value of 31.5 billion won per year. The results of measuring the conservation value provide decision-makers with data indispensable to devising a conservation and management policy.
