WTP_small indicates WTP elicitation using a small-range price list, etc. Entries in PPP adjusted 2017 international $. Price stands for the amount respondents are willing to pay or receive on an annual basis. The 95% Confidence Interval is constructed around the median, using the standard built-in procedure (the centile command) in Stata. The GDP per capita annual income in PPP dollar in Burkina Faso is $1,862 in 2017
^aThe median VSLY is tested against the WHO-recommended three times per capita income, non-parametric two-sided sign tests
