Happiness on Tap: Piped Water Adoption in Urban Morocco
研究发现，摩洛哥城市家庭愿意贷款接入自来水，并非因为健康改善，而是因为节省时间、减少家庭冲突，从而持续提升幸福感。这对推动生活质量投资有启示。
Connecting private dwellings to the water main is expensive and typically cannot be publicly financed. We show that households' willingness to pay for a private connection is high when it can be purchased on credit, not because a connection improves health but because it increases the time available for leisure and reduces inter- and intra-household conflicts on water matters, leading to sustained improvements in well-being. Our results suggest that facilitating access to credit for households to finance lump sum quality-of-life investments can significantly increase welfare, even if those investments do not result in any health or income gains.
