The value of improved water quality in Guadiana estuary—a transborder application of contingent valuation methodology

“…This model has been used extensively in CV methods (Genius and Strazzera 2002;Bengochea-Morancho et al 2005, Haltia et al 2009Diaz et al 2010). The popularity of Logistic Regression is not surprising since the model has some outspoken advantages (Coussement et al 2010).…”

Affordability of Decentralized Wastewater Systems: A Case Study in Integrated Planning from INDIA

“…As to these problems, in India the logit model for WTP (it assumes a logistic distribution of WTP; see Equation (4) in Section 6) is most common in use amongst water management researchers [19,20]. However, it is known that this model does not always provide realistic results [21], as its implicit distribution assumption may be false, as was observed for the present case study. Second, WTP studies typically require large samples of 200 to 2500 interviews [22][23][24], whereas decentralized systems serve a small population (e.g., initially 1000-2000 HHs at the present case study sites) and their planning budgets might finance only small surveys (e.g., 50-100 HHs for this study).…”
