In light of the growing interest and potential of the Life Satisfaction Approach (LSA) to value environmental attributes, this research paper aims to estimate the monetary value of water supply infrastructure improvements using this novel approach. A theoretical framework compares this method with the widely used contingent valuation method (CVM), highlighting the pros and cons of both approaches. Results show that the LSA can generate meaningful values of the nonmarket benefits derived from improving water supply infrastructure, based on the impact that such benefits can have on individuals’ life satisfaction. In addition, these values are not different from those obtained from the CVM. Thus the LSA arises as a useful complement to the more traditional methods while expanding the array of techniques available for the economic valuation of environmental goods in a cost benefit framework.

使用生活满意度数据作为或有估值的补充来评估供水基础设施的改善

鉴于人们对生活满意方法（LSA）重视环境属性的兴趣和潜力越来越大，本研究旨在使用这种新颖的方法来估计供水基础设施改善的货币价值。一个理论框架将该方法与广泛使用的或有估值方法（CVM）进行了比较，突出了这两种方法的优缺点。结果表明，LSA可以根据改善供水基础设施而产生的非市场收益产生有意义的价值，这些收益对个人生活满意度会产生影响。此外，这些值与从CVM获得的值没有不同。
