Task familiarity and contextual cues predict hypothetical bias in a meta-analysis of stated preference studies

Traditional stated preference theory does not provide useful guidance on hypothetical bias because the bias lies outside the theory. Not surprisingly, meta-analyses using variables from the theory have not revealed consistent patterns of bias. We find that these models are substantially improved by...

Zusammenfassung:Traditional stated preference theory does not provide useful guidance on hypothetical bias because the bias lies outside the theory.

These results lead us to recommend survey procedures that address these concerns.
