摘要我们使用享乐价格法来研究获得供水后资本化房屋价值的变化，估计了萨尔瓦多三个城市家庭自来水的年化价值以及危地马拉四个城市的边缘“巴里奥斯”。在我们的样本中，自来水连接使房屋的销售价值增加了10%至52%。获得自来水的估计平均值占家庭真实的收入的1- 5%，各城市不同，萨尔瓦多的平均值一般较高。平均而言，这一收益消除了有联系和无联系家庭群体之间最初真实的收入差异的1%至3%。我们还发现，根据非自来水的主要来源，水龙头连接的价值差异很大，当水源是萨尔瓦多的私人水井时，价值最低。
ABSTRACT We estimate annualized values of access to home tap water in three cities in El Salvador, and marginal ‘barrios’ in four Guatemalan cities, using a hedonic price method for studying changes in capitalized home values from obtaining a water connection. A tap water connection is found to add from 10 per cent to 52 per cent to sales values of homes in our sample. The estimated mean values of gaining tap water access represent 1–5 per cent of real household income, differing by city and with generally higher values in El Salvador. On average this gain eliminates between 1 per cent and 3 per cent of the initial difference in real incomes between the groups of connected and unconnected households. We also find large differences in the value of a tap connection depending on the main source of non-tap water, with lowest values when the source is a private well in El Salvador.
