How Undervalued is the COVID-19 Vaccine? Evidence from Discrete Choice Experiments and VSL Benchmarks

Two discrete choice experiments conducted early in the Covid-19 vaccination campaign show that people dramatically undervalue the Covid-19 vaccine, relative to benchmarks implied by the value of a statistical life (VSL). Our first experiment found that median willingness to pay (WTP) for initial vaccination is around $50, only 2 percent of the WTP implied by standard VSL calculations. Our second experiment found the median person was willing to accept (WTA) about $200 to delay the second dose, only 32 percent of the WTA implied by standard VSL calculations. While standard economic models imply that vaccines are undervalued because of their large externalities, we interpret the finding that WTP estimates are well below the VSL benchmarks as evidence that internalities play a substantial role. This evidence that people undervalue even the private benefits of vaccination suggests that there may be a role for government beyond conventional efforts to correct externalities
