Willingness to Pay for a Hypothetical COVID-19 Vaccine in the United States: A Contingent Valuation Approach

Willingness to Pay for a Hypothetical COVID-19 Vaccine in the United States: A Contingent Valuation Approach

Serkan Catma, Serkan Varol

Our objective was to estimate the individual willingness to pay (WTP) for a COVID-19 vaccine and evaluate its predictors in the United States. A double-bounded dichotomous choice contingent valuation with open-ended question technique was implemented based on the responses to a national survey administered during the first week of November 2020. The final sample size was 1285. The results showed that individual WTP values increased with income, whether a household member had any pre-existing condition, and perceived threat of the virus. The vaccine efficacy rate and duration of protection were found to be important factors for the respondents. The mean WTP for a vaccine with a 95 percent efficacy rate and 3-year protection (US$318.76) was approximately 35 percent greater than the vaccine with a 50 percent efficacy rate and 1-year protection (US$236.85). The initial aggregate direct benefit of the current vaccination program was estimated to be between 20 and 35.6 billion US dollars depending on the vaccine protection duration.
