Abstract The recent literature on agricultural technology adoption shows that diffusion of new technologies varies significantly across space and time. Furthermore, puzzles exist about why some seemingly profitable technologies are not adopted, especially in livestock production. We employ a hazard or duration function to explain diffusion of crossbred‐cow technology in a unique sample of Tanzania farmers. A farmer's adoption of crossbred technology depends positively on the proximity of his farm to other users, on his schooling, and on his access to credit and contact with extension agents.
