Text: 21 Note that the Environmental Economics Advisory Committee (EEAC) of the SAB advised EPA to adjust WTP for increases in real income over time, but not to adjust WTP to account for cross-sectional income differences because of the sensitivity of making such distinctions, and because of insufficient evidence available at present (EPA-SAB-EEAC-00-013).
Entailment: There insufficient evidence at this time to justify adjusting the WTP to account for cross-sectional income differences.
Contradiction: The EEAC neglected to advise the EPA about the WTP.
