Fig. 2: WTP for improvements in drinking water quality.
From: Benefits, costs and enabling conditions to achieve ‘water for all’ in rural and remote Australia
Parametric mean WTP (data points) and 95% confidence intervals (error bars) for three proposed levels of improvement, that is, 25%, 50% and 100%, in drinking water quality for 260,000 people living in the 395 SRR communities that were known to be exposed to substandard drinking water in 2018–2019. Model 1: full sample; Model 2: only payment consequentiality; Model 3: only payment consequentiality and tax attendance, certainty calibration.
