Scope Issue in Contingent Valuation Studies of the COVID-19 Vaccine: The Case of China.

ABSTRACT:

Background

Assessing the public's willingness to pay (WTP) for the coronavirus disease 2019 (COVID-19) vaccine by the contingent valuation (CV) method can provide a relevant basis for government pricing. However, the scope issue of the CV method can seriously affect the validity and reliability of the estimation results.

Aim

To examine whether there are scope issues in respondents' WTP for the COVID-19 vaccine and to further verify the validity and reliability of the CV estimate results.

Method

In this study, nine different CV double-bounded dichotomous choices (DBDC) hypothetical COVID-19 vaccine scenarios were designed using an orthogonal experimental design based on the vaccine's attributes. A total of 2450 samples from 31 provinces in Mainland China were collected
