“…Our sample was allocated to the strata in proportion to each stratum's population characteristics, such as age, income, and gender, resulting in 22 to 230 households being assigned to each stratum. For example, the numbers of surveys allocated to households in Seoul, Busan, Daegu, Incheon Gwangju, Daejeon, Ulsan, Gyunggi, Gangwon, Chungbuk, Chungnam, Jeounbuk, Jeounnam, Gyungbuk, and Gyungnaum were 197, 71, 50, 55, 30,32,22,230,33,33,45,38,39,58, and 67, respectively. A random sampling was implemented within each stratum.…”

Abstract:Northern fur seals (Callorhinus ursinus), especially those that live in Dokdo, Korea, represent an endangered species in Korea. Thus, the government is considering the implementation of the Dokdo Seals (DS) restoration project. This article looks at the economic benefits for implementing the project, which includes making habitats for the DS, such as an artificial sea ranch, and training DS rescued from fishing nets and wounded in the wild to adapt to the wild so that they can be released into the Dokdo Sea. To this end, we looked at the willingness to pay (WTP) for the implementation of the project by conducting a contingent valuation (CV) survey of 1000 Korean households. We employed a one-and-one-half-bounded dichotomous choice question format. Furthermore, we used a spike model to model the WTP responses with zero observations. The mean yearly WTP for the project implementation was computed to be KRW 4923 (USD 4.86) for next ten years per household, which is statistically significant at the 1% level. The national annual value amounts to KRW 90.9 billion (USD 89.8 million). This value can be taken as an indication of the economic benefits of restoring the endangered species.

“…SP methods usually ask people to state their WTP for consuming the goods or services concerned. Two representative approaches belonging to SP methods are the CV approach and the choice experiment (CE) approach [17][18][19][20][21][22][23]. The former elicits the WTP response directly, whereas the latter derives the WTP responses indirectly.…”

Do People Place More Value on Natural Gas Than Coal for Power Generation to Abate Particulate Matter Emissions? Evidence from South Korea

Abstract:As of 2017, coal is responsible for about half of all power generation in South Korea, while natural gas (NG) is responsible for about 20%. This increases particulate matter (PM) emissions, as coal emits 6 to 55 times more PM than NG in the course of power generation. Increased PM concentration causes visibility impairment and acute respiratory diseases. Thus, the South Korean government is seeking to shift from coal to NG power generation for the purpose of abating PM emissions. The government also considers NG as a bridge energy to facilitate the transition from fossil fuels to renewable energy. This article attempts to answer the question, "Do people place significant value on shifting from coal to NG power generation in order to abate PM?" To this end, additional willingness to pay (WTP) for NG over coal for electricity for the purpose of PM emissions abatement was assessed from 1000 South Koreans' contingent valuations (CV). More specifically, each of these randomly chosen interviewees was asked about her/his WTP for the switch from coal to NG for 1 kWh of electricity use. The average additional WTP estimate was KRW 31.27 (USD 0.028) per kWh, which is equivalent to 28.8% of the average price of electricity in 2017. Moreover, this estimate is statistically significant. The generation cost of NG is about KRW 100.13 per kWh, which is higher than that of coal (KRW 78.5 per kWh). The gap is KRW 22.08 per kWh, which is less than the additional WTP. Thus, it is obvious that the governmental policy of shifting from coal to NG for power generation in order to abate PM emissions is supported by the public and, hence, the shift should be made gradually.

“…We utilized a spike model to analyze our OOHB DC CV data with a number of zero observations. The spike model was originally proposed for SB DC CV data by Kriström [33], was adjusted for DB DC CV data by Yoo and Kwak [34], and is sometimes applied to OOHB DC CV data (e.g., [21,35]). Let the random variable for the WTP be W and the cumulative distribution function of the WTP be H W (·).…”

Abstract:Although the production costs and prices of eco-labeled products are higher than those of conventional ones, the use of greener products can lead to better environmental outcomes. Thus, the consumers' preferences for eco-labeled products should be investigated to understand the potential of markets with green products. This study attempts to examine the consumers' preference or willingness to pay (WTP) a premium for eco-labeled products using a specific case study of a 43-inch LED TV, which is a common home appliance in Korea. For this purpose, a contingent valuation survey of 1000 Korean consumers was conducted in June 2016. We used a one-and-one-half-bounded dichotomous choice question to derive the additional WTP responses and a spike model to analyze zero additional WTP responses. The mean additional WTP a premium for the eco-labeled 43-inch LED TV is estimated to be KRW 29,007 (USD 24.8), which is statistically meaningful at the 1% level. This value amounts to 3.9% of the price of a conventional 43-inch LED TV (KRW 750,000 or USD 640.5) and can be interpreted as the external benefit of an eco-labeled LED TV. We can conclude that Korean consumers are ready to pay a significant premium for eco-labeled LED TVs. Moreover, we examined the consumer's characteristics that affect the probability that the person will be willing to pay a premium for an eco-labeled LED TV and found that it would be effective to set high-income, older, highly-educated, and female consumers with children as marketing targets.
