In this paper we assess the performance of farmers adopting an improved sorghum technology package in the Maradi region of Niger. A propensity score matching method is used to address self-selection bias into the program. First, we estimate a propensity model to participate in the extension...

We provide a general framework for quantifying the effects of genotypic selection prediction accuracy and varying cost ratios of phenotyping to genotyping on the economic performance of genotypic selection relative to traditional phenotypic selection. Economic performance is measured using...
