Elicitation formats and the WTA/WTP gap: A study of climate neutral foods

We conduct a field valuation experiment where we vary the valuation method (contingent valuation vs. inferred valuation) as well as the payment format (dichotomous choice vs. payment card). Willingness-to-accept and willingness-to-pay valuations are elicited in a within-subjects design for foods with climate neutral labels. We find a similar gap for valuations elicited with the contingent or the inferred valuation method. However, we also find that the gap can be muted by using a payment card elicitation format.
