Description

We present and field-test a novel mechanism to elicit the willingness to pay for multiple instead of a single unit of a good. At each price of the canonical multiple price list (MPL) approach, we elicit varying multi-unit demand instead of limiting the choice to two options. We showcase our mechanism by applying it in the Lake Victoria fisheries of Tanzania to elicit valuations for fishing net panels, a production input generally purchased in bulk. Our application demonstrates the mechanism in a challenging field environment and gives best practice advice on minimizing common weaknesses of the MPL approach.
