A new meta-analysis on the WTP/WTA disparity
Research-assisted source review
- What it supports
- Gaps were smaller for ordinary private goods, student samples, experienced participants, repeated trials, incentive-compatible procedures and more recent studies. Public and non-market goods produced larger disparities on average.
- Where it may not transfer
- The analysis combines heterogeneous goods, populations and elicitation methods and focuses on group mean valuations. It does not identify a single psychological mechanism or estimate subscription churn, digital attachment or product usability.
