  • The paper is to estimate willingness-to-pay (WTP) for tap water quality improvement in Busan, using parametric approach in contingent valuation method(CVM). For parametric approach linear logit model and log logit model are employed in double-bounded dichotomous choice format of CVM. For the reliability and the validity of contingent valuation method a survey was conducted for 665 respondents, who were sampled by stratified random sampling method, by personal interview method. The result of mean WTP for the tap water quality improvement in Busan was estimated to be 3,687 won and 3,660 won per month per household, while median WTP being 1,884 won and 1,892 won per month per household, respectively by linear logit model and log logit model. Provided that our sample is broadly representative of the Busan's population, an estimate of the annual aggregated benefit of residential water improvement for all Busan households is approximately 29.7 billion won to 29.8 billion won based on median WTP.

  • This study investigated consumers' perceptions and willingness to pay (WTP) for fruit and vegetables grown using renewable energy such as solar power, geothermal, waste heat from incinerators, hot water from thermal power plants. To this end, this study conducted an online survey of 1,050 consumers in Seoul, Gyeonggi, and the six metropolitan cities, and the main findings are as follows. First, most of the consumers perceived climate change as a serious problem, and 82.8% recognized the government's declaration of carbon zero was appropriate, which means that the government's active response to climate change is important. Second, on the pros and cons of the use of renewable energy when cultivating fruits and vegetables, opinions in favor of solar power were the highest, followed by geothermal heat, waste heat from waste incineration plants, and thermal power generation hot drainage. Third, at least 28.0% to 41.7% of consumers were willing to purchase fruits and vegetables using renewable energy more expensive than fruits grown using fossil energy such as kerosene. This means that the fruit and vegetable market using renewable energy is valuable as a niche market.
