Value of statistical life (VSL) estimates

	Questionnaire one “Willingness to Pay”	Questionnaire two “Willingness to Accept”	t-test for significant questionnaire effect
Mean VSL (US $)	238 963	258 331	0.42 $p < 0.68$
Mean VSL (US $)	(18 920)	(38 493)

Median VSL (US $)	283 211	307 838	0.34 $p < 0.74$
Median VSL (US $)	(27 429)	(48 758)

Note: $N = 300$ . The point estimates are weighted. Standard errors in parentheses (and t-tests for questionnaire effects) corrected for clustering, stratification, and weighting. The standard error of the median comes from an intercept-only quantile regression with 100 cluster bootstrapped replications.

The VSL estimates for each respondent are obtained by applying Eqn. (3) in the text to the values generated from the survey.
