| This study investigates the economic valuation of air-pollution-related health risks in China by applying the contingent valuation method. An individual interview survey is conducted to elicit resident's willingness-to-pay (WTP) for health risk reductions of asthma and mortality. Binary choice WTP question is used in the in-person interview. Using binary probit model, the estimated value of a statistical case of asthma is about US$2300, median VSL estimated is about US $24,000. The issues of private and public provision mechanisms of health risk reduction, and the scale effect of the WTP to the magnitude of risk are also discussed. |

| Spatial accessibility is concerned with the opportunity that an individual at a given location possesses to participate in a particular activity or set of activities. The main objective of this paper is to highlight the shortcomings of traditional accessibility measures and provide some appropriate methodological suggestions for their improvement. Traditional measures derived from cumulative opportunities and gravity models focus on physical proximity leaving out individual and spatial attributes as potential explanatory variable. The improvement through random utility theory relies mainly on Multinomial logit models under Independently and Identically Distributed (IID) and individual response homogeneity assumptions that often do not hold in case of... |
