An integrated socioeconomic analysis of innovation adoption: The case of hybrid cocoa in Ghana

This study employs a multidisciplinary model to explain the adoption of agr icultural innovations in developing economies with reference to hybrid coco a in Ghana. The empirical evidence shows that, in the adoption of hybrid co coa, the support that small-scale farmers obtain via their social networks is more relevant than the advantage of farm size enjoyed by large-scale far mers. However, for large-scale farmers, access to a bank loan strongly incr eases their chance of adoption compared with small-scale farmers. Contacts with extension agents, education, and availability of hired labor also have positive effects on adoption. The social status of the farmers has only an indirect effect on adoption: farmers with higher social status are more li kely to obtain a bank loan, and a bank loan has a positive impact on adopti on.
