We answer this question using a randomization evaluation of a willingness-to-pay (WTP) experiment itself, rather than the effect of winning or losing the auction. Comparing households in WTP villages and a pure control, as well as winners and non-winners of the auction, we followed household outcomes over a four-year period. Households in WTP villages adopted and used the technology over a three-year period, beyond its traditional sh
