Dataset for: Eliciting farmers’ demand for quality and nutritionally enhanced sweetpotato planting material in Rwanda

To date, however, projects and NGOs are the major buyers of quality vines from Descentralized Vine Multipliers while the majority of farmers obtain their sweetpotato planting material from own sources or neighboring farmers. This leads to the following research questions: what premium price are farmers willing to pay for quality vines and what are the drivers of the demand for quality vines? Are farmers willing to pay a premium for the high beta carotene nutritious biofortified varieties?

The database present the data of the a willingness to pay (WTP) approach using auctions. Based on this design, each participant had a total of 11 bids (3 bids in Round 1 and 2 bids in the subsequent 4 rounds). In addition to estimating the average WTP for quality seed and a biofortified sweetpotato (i.e., OFSP) variety, econometric models will be estimated to examine the factors that affect WTP for quality seed and the biofortified sweetpotato variety.
