Particulate air pollution is a serious problem and has received extensive attention in Beijing. The public might amplify the health risks because of the visibility and frequency of haze, potentially leading to anxiety and panic. Public risk perception might affect individual behaviors and their willingness to pay for improving air quality. We used contingent valuation method and psychometric paradigm to investigate public risk perception and elicit willingness to pay for reductions in the health risk posed by fine particulate matter 2.5 smaller than 2.5 microns in width in Beijing, China. The logit model results showed that the level of fear and four characteristics of risk perception—familiarity, scope of impact, relevance to individual, and voluntariness—had significant effects on respondents’ payment decision. The ordinary least squares model results showed the level of anxiety, anger, and satisfaction about the current situation and four characteristics of risk perception—scope of impact, overall risk, duration of effects, and controllability—had significant effects on the amount of willingness to pay.

“…First, studies that assessed people's additional WTP for electricity generated from NG-based CHP plant over coal-fired plant to mitigate air pollutants emissions remain scarce. Most of the related research has tackled public value for reducing the air pollutions or improving the air quality [17][18][19][20][21][22][23].…”

Willingness to Pay for Substituting Coal with Natural Gas-Based Combined Heat and Power in South Korea: A View from Air Pollutants Emissions Mitigation

2018

As of 2017, coal-fired generation is responsible for about half of electricity generation in South Korea. This causes a serious problem of emitting air pollutants such as particulate matters, sulfur oxides, and nitrogen oxides. Thus, the South Korean government is seeking to substitute a part of coal-fired generation with natural gas (NG)-based combined heat and power (CHP) generation for the purpose of mitigating air pollutants emissions. This article tries to assess the public willingness to pay (WTP) for the substitution adopting contingent valuation (CV). The data on the additional WTP for consuming 1 kWh of electricity produced from NG-based CHP generation over coal-fired generation were gathered from a CV survey of 1000 interviewees. The mean additional WTP estimate for the substitution is obtained as KRW 28.08 (USD 0.025) per kWh of electricity use. This is equivalent to 25.9% of the average price of electricity, KRW 108.50 (USD 0.098) per kWh in 2017. It is obvious that the South Korean public has a significant WTP for substituting coal with NG in electricity generation to mitigate air pollutants emissions. The government needs to gradually push for the substitution.

“…In response to this concern, researchers had proposed to explicitly highlight the hypothetical problem in a script before respondents could make any decisions (cheap talk script) (Ami et al, 2011;Cummings & Taylor, 1999;Mahieu, 2010;Murphy et al, 2005b), remind the respondents that their decisions are consequential and could be used by policymakers about the provision of the public good or implementing the health policy (Bulte et al, 2005;Liu et al, 2010), give respondents time to think (Cook et al, 2011;Donfouet et al, 2015;Whittington et al, 1992), calibrating the respondents' answers using ex-post correction based on the certainty of respondents to the WTP questions (Blumenschein et al, 2008;Champ et al, 1997;Johannesson et al, 1999), and ask the respondents to make a commitment to tell the truth (oath script) (Jacquemet et al, 2013). In the current study, we explicitly used the oath script.…”

The failure of the market and government to provide quality healthcare services have been the motivation to set up social health enterprise. However, the value for money associated with setting up a social health enterprise in sub-Sahara African countries has been relatively unexplored in the literature. The study presents the first empirical estimates of the mean willingness-to-pay (WTP) for setting up a social health enterprise that will simultaneously run a health center and provide health insurance scheme in an urban resource-poor setting and explores whether the benefits outweigh the costs. The contingent valuation method is used to estimate the mean WTP for the health insurance scheme proposed by the social health enterprise in Viwandani slum (Nairobi, Kenya). The survey was conducted between June and July 2018 on 300 households. We find that the feasibility of setting up a social health enterprise could be promising with 97 percent of respondents willing to pay about US$ 2 per person per month for a scheme that would provide quality healthcare services. More importantly, setting up the social health enterprise will yield a positive net profit, and investors could expect US$ 1.11 in benefits for each US$ 1 of costs of investment in setting up the social health enterprise. We, therefore, conclude that this health policy in this urban resource-poor setting could be a viable solution to reach the neglected urban households in the Kenyan slums.
