Abstract
Simultaneous models are often appropriate for estimating high-yielding variety (HYV) adoption, but most empirical investigations have been b ased on single-equation models. Using the econometric application of a model for hybrid maize adoption in Malawi as an illustration, this pa per argues that researchers investigating HYV innovations need to cons ider methods for estimating simultaneous censored systems. Further wor k with associated estimation procedures and diagnostic tests is needed to improve the measurement and prediction of seed-fertilizer adoption .
