We estimate willingness to pay (WTP) for better quality of tap water on a unique cross-section sample from 10 OECD countries. On the pooled sample, households are willing to pay 7.5% of the median annual water bill to improve the tap water quality. The highest relative WTP for better tap water...

Cost-benefit analyses are commonly applied to assess the net welfare effects of policies to improve surface water quality. These analyses often disregard the biophysical fact that from implementation of policy measures to resulting improvements on water quality there will typically be...
