The Decision to Adopt and the Intensity of Adoption of Technology: A Double Hurdle Model Application in the Adoption of a Sorghum Hybrid

Abstract: This paper argues that the double-hurdle model is more appropriate to identify the socioeconomic variables that influence adoption when agricultural technologies are scarce. In such cases the variables identified by probit or tobit models may confound the ability to acquire the scarce technology with the motivation to adopt. The double-hurdle model precludes this problem by separating the adoption process in two stages, the decision to adopt, and the decision on the degree of use of the technology. Estimating the two “hurdles” separately provides additional insight into the data. This is illustrated with the adoption of a sorghum hybrid in Sudan. The empirical results show that the decision to adopt and the decision on the intensity of adoption is explained by different sets of variables. The policy implications of this outcome are highlighted.
