Air Quality Improvement

The purpose of the study is to estimate the air quality improvement in the urban areas of HoChiMinh City (HCMC) through resident’s willingness to pay (WTP) by using contingent valuation method. 300 residents were chosen to participate in an interview with the structured questionnaire and the open-ended question about their WTP. The results show that with the performance of ambient air in HCMC, 88.41% of respondents are willing to pay for this "particular commodity". The average WTP for a 50% reduction of concentration of air pollutants in next 5 years in HCMC, where respondents live and work was 19,732 VNĐ/household/month, accounted 0.15% of a household income. Positive WTP values reveal that residents have a choice between better air quality and rapid growth of the economy, which also means that air quality is really their considerable economic value. Therefore, this value should be considered in the cost – benefit analysis of projects or programs relating to air quality. The results are the source of useful information for policy makers to decide in the investment and policy measures to reduce impacts on air quality in the process of economic development.

Valuation Method

Hydroelectric power plants and dams often play an important role in developing countries in terms of their contribution to economy. In accordance with the energy policies of Turkish Republic, Yusufeli Dam and Hydroelectric Power Plant in Northeastern Turkey have been initiated. In this study, the Contingent Valuation Method (CVM) was conducted in Yusufeli Village to determine the environmental costs of the Yusufeli Project. The purpose is to assess the willingness to pay (WTP) of Yusufeli Village residents for restoration of the environmental impacts of the dam project and also to investigate the underlying economic, psychological, and social motivations for WTP. WTP was calculated as US$761 per person which can further be used in the cost–benefit analysis. The results from the study suggest that application of the CVM in rural and urban areas located in the same region can show differences.

Air Quality Improvement

Thailand has experienced severe air-quality problems for the past 10 years. Complicating this situation, the Thai government allocates an insufficient budget for the management of air pollution. Using the contingent valuation method, this paper estimates the willingness to pay for air-quality improvement in Thailand to reveal the benefits that people will gain if air-quality improves. The results show that the total benefits from air-quality improvement would be 18.8 billion baht in 2020. The Thai government can use these findings as a guideline to redistribute its budget to address air pollution more effectively.

The Mean

Air pollution in Tehran, the capital city of Iran, has led to poor air quality, with consequences for the health of residents. This study uses a contingent valuation method to estimate the willingness to pay of Tehran’s residents for air quality improvement. Open-ended and stochastic payment card approaches were used to determine the willingness to pay of the sample. The mean individual willingness to pay for a specified air quality improvement was approximately US $6.40 per month, and the variance of the willingness to pay was approximately U.S. $4, as estimated using the SPC approach. Open-ended questions revealed that the mean individual willingness to pay was approximately U.S. $4 per month. Significant positive effects of income, use of public transportation, marriage, job and health status on the mean willingness to pay were observed. Although most respondents believed that air quality improvement is the government’s responsibility, they are willing to bear the cost as a supplement to achieve better air quality.

Valuation Method

It is difficult to quantify and value many of the benefits of education. This paper illustrates the use of contingent valuation to obtain more complete estimates of the economic value of difficult-to-measure benefits of preschool education for handicapped children and presents a general approach for the use of contingent valuation in cost-benefit analysis of educational programs. Data for the illustration were obtained by surveying parents of children with handicapping conditions enrolled in preschool special education programs in Iowa. The survey was conducted jointly by the Department of Economics and the Early Intervention Research Institute at Utah State University. Results indicated that the contingent valuation method produces plausible results which are consistent with basic predictions of economic theory. Implications for policymaking and directions for further research are discussed.
