Each reported significance level is for the most preferred model under each specification, based on the minimum AIC from Tables 4, 5, 6 and 7

Bootstrapped standard errors used for models without IPW; robust standard errors used for models with IPW (bootstrapping does not allow for weights)

IPW inverse probability weighting, WTP willingness to pay, GLM generalized linear model, AIC Akaike Information Criterion

***p < 0.01, **p < 0.05, *p < 0.1
