CONTINGENT VALUATION METHOD
Contingent valuation (CV) is a type of stated-preference study that uses surveys to elicit willingness-to-pay (WTP) for goods and services that have not yet been introduced into the market, subject to a budget constraint. The four common CV methods used are dichotomous choice, open-ended questions, bidding game and payment card.
The DOVE-CV project focuses on how best to conduct CV studies to obtain more valid and less biased WTP estimates for mortality risk reductions in resource-poor settings. To this end, we have performed a literature review on contingent valuation studies from low- and middle-income countries in order to make a preliminary assessment of the conditions and resources needed to apply these methods, and explore the current evidence gaps.
With emphasis on Gavi-Asia countries (Bangladesh, specifically) the DOVE-CV team is performing a pilot study to understand what methods are best suited for the Bangladeshi context, as well as investigating the role of cognitive interviews in ensuring participants’ understanding of questions, to allow for more valid WTP estimates. We will be eliciting WTP for mortality risk reductions for vaccine-preventable diseases, through a quasi-randomized convenience sample of every 10th patient at two health facilities in Bangladesh. This project is currently in the planning phase.
