Inferences from the counterfactual distribution

Kolmogorov-Smirnov test
(p value)
Cramer-von-Misses-Smirnov
(p value)
Comparison of WTP model specification (H0 = correct specification) 0.24 0.24
Comparison of WTA model specification (H0 = correct specification) 0.46 0.46
Differences between observed distributions
H0: No effect found, the difference between quantiles is zero for any chosen quantile < 0.001 < 0.001
H0: the difference between quantiles is constant and equal to the difference between medians < 0.001 < 0.001
Stochastic dominance (WTA stochastically dominates WTP) < 0.001 0.020
Inverse stochastic dominance (WTP stochastically dominates WTA) 0.640 0.640
