Predictions of the incentive amount racial/ethnic minority adults in Rhode Island would be willing to accept for COVID-19 vaccination. Figure shows the predicted probabilities associated with the incentive amounts needed for others to be willing-to-accept COVID-19 vaccination as well as respondents themselves to be WTA vaccination based on results from the margins post-estimation command. Probabilities were predicted using higher theoretical incentive amounts ranging from USD$50 – $250 per dose, and do not represent WTA probabilities from contingent valuation survey data. Horizontal reference line is set at 85% based on the upper bound of most commonly cited immunization rates needed to reach herd immunity in the entire U.S. population.20 WTA: Willingness-To-Accept
