- Two contingent valuation framings applied to obtain WTA for conservation contracts.
- Auction framing resulted in lower mean WTA and sample variance than standard.
- Auction framing more meaningfully correlated with socio-demographic drivers.
- WTA positively correlated to measures of foregone rent from halting deforestation.
- Promising potential of WTA methods for designing future conservation strategies.
