“…For each set, four initial bids were chosen to produce "reasonably efficient and robust estimates" [38], the value of which was determined with reference to the findings from previous studies. According to Kim et al [9], the estimated mean WTP for enforcing PM 2.5 concentration reduction policy in Korea is KRW 5591 (USD 4.97) per household per year, whereas Wei and Luo [31] assessed an average WTP for PM 2.5 control in the Beijing-Tianjin-Hebei Region as CNY 65 (USD 9.47) per person per month. Therefore, initial bids for Korea started from KRW 5000 (USD 4.46) with an incremental amount of KRW 5000 for the next initial bid, and those for Chinese respondents started from CNY 20 (USD 2.91), with CNY 20 as the incremental amount for the next initial bid.…”

“…The number of PM 2.5 warnings issued (when the PM 2.5 concentration surpasses 90 µg/m 3 and stays over 2 h) has continued to increase, from 72 in 2015 to 92 in 2017 [8]. With the growing public concern about the related health impact, PM 2.5 has turned into a big social issue in Korea [9]. The Korean government has taken various mitigation and responsive actions to deal with the PM 2.5 issue.…”

This research aimed to examine the willingness to pay (WTP) of the young generation (the age group from 18 to 29) for the participatory solutions and actions on fine particulate matter (PM2.5) pollution control and abatement in Daegu, Korea, and Beijing, China. This study found out that Korean respondents and Chinese respondents shared a wide range of similarities, both in terms of socio-demographic characters like age, family size, and house/apartment ownership, as well as a number of perceptions related to environmental and social responsibilities. Around one-third of the Korean respondents and one-fifth of the Chinese respondents expressed negative WTP due to primary reasons such as lack of trust in the effectiveness of PM2.5 control measures (Korea) and limitation of budget (China). The mean estimated values of WTP with and without explanatory variables in Korea were merely slightly higher than those in China. The mean WTP without control variables in Korea was 11,882.97 KRW/month (10.61 USD/month) and the one in China was 65.09 CNY/month (9.48 USD/month). The mean WTP with explanatory variables for Daegu, Korea, was KRW 11,982.33 (USD 10.70) per person per month, and the one for Beijing, China, was CNY 64.84 (USD 9.40) per person per month. The annual total WTP for Daegu, Korea, was assessed around KRW 47572 million (USD 42.45 million), whereas the estimated total WTP for Beijing, China, was around CNY 3260.14 million (USD 474.94 million) per year. Based on the results and the findings, this study proposes to further strengthen the comprehensive cooperation between China and Korea in the field of air quality improvement, with a particular focus on PM2.5 control and abatement and cooperation in academic circles and among the general public.

“…For decades, particulate matters with aerodynamic diameters less than 2.5 micrometers (PM2.5) have attracted significant attention in the Republic of Korea. According to the Ministry of Environment, the national average concentration of PM2.5 increased from 28 µg/m 3 in 2015 to 30 µg/m 3 in 2016, and reached 31 µg/m 3 in 2017 [1] which is three times higher than the World Health Organization (WHO) annual guideline(10 µg/m 3 ) [2]. Various environmental epidemiology studies have identified significant positive associations between exposure to airborne PM2.5 and the exacerbation of chronic or acute disease symptoms [3,4], increased mortality risk [5], decreased life expectancy [6], and low birth weight [7].…”

Assessment of Daily Personal PM2.5 Exposure Level According to Four Major Activities among Children

Particulate matters less than 2.5 micrometers in diameter (PM2.5), whose concentration has increased in Korea, has a considerable impact on health. From a risk management point of view, there has been interest in understanding the variations in real-time PM2.5 concentrations per activity in different microenvironments. We analyzed personal monitoring data collected from 15 children aged 6 to 11 years engaged in different activities such as commuting in a car, visiting a commercial building, attending an education institute, and resting inside home from October 2018 to March 2019. The fraction of daily mean exposure duration per activity was 72.7 ± 18.7% for resting inside home, 27.2 ± 14.4% for attending an education institute, and 11.5 ± 9.6% and 5.3 ± 5.9% for visiting a commercial building, commuting in a car, respectively. Daily median (interquartile range) PM2.5 exposure amount was 88.9 (55.9–159.7) μg in houses and that in education buildings was 43.3 (22.9–55.6) μg. Real-time PM2.5 exposure levels varied by person and time of day (p-value < 0.05). This study demonstrated that our real-time personal monitoring and data analysis methodologies were effective in detecting polluted microenvironments and provided a potential person-specific management strategy to reduce a person’s exposure level to PM2.5.

“…Second, the interval of sets of bids becomes larger. This method, proposed by Cooper et al [36], is a common practice in the one-and-one-half-bounded (OOHB) dichotomous choice (DC) question method. Thus, this article followed this method proposed by Cooper et al [37].…”

“…The authors sorted the reported positive values in ascending order, trimmed 10% of observations from both tails, and determined seven bids from the trimmed distribution in a manner of increasing interval. Seven sets of bids are widely used in various papers (e.g., [20,36]). Thus, we followed previous papers and used seven sets of two bids, determined through a pretest of a focus group.…”

The Public Willingness to Pay for Reducing the Incidence of Hazardous Chemical Spill Accidents by Half in South Korea

Abstract:Hazardous chemical spill (HCS) accidents, which occur due to careless workers, transport accidents, etc., can be harmful to humans. Recently, an average of 96 cases of HCS accidents have taken place in South Korea annually. As a result, the government is trying to reduce the incidence of HCS accidents by 50%. Government officials are seeking information about the value that the enforcement of the reduction plan will bring for the public. This knowledge will help government officials decide whether to implement the reduction plan. This article seeks to acquire information about the public willingness to pay (WTP) for the reduction plan, employing the contingent valuation (CV) technique. For this purpose, a total of 1000 households living in South Korea participated in the CV survey in 2017. The data on the WTP were gathered using a dichotomous choice question and analyzed using the spike model. Forty-five percent of the respondents were willing to accept an increase in income taxes to carry out the reduction plan. The mean household WTP estimate was obtained as KRW 3830 (USD 3.41) per annum. The national value expanded from the sample to the population is worth KRW 74.8 billion (USD 66.6 million) per year. This value implies the public value of the reduction plan and can be applied in policy analysis and decision-making concerning the reduction of the incidence of HCS accidents.
