| description | This paper applies duration analysis to identify the factors that shorten the time until a farmer replaces one modern variety with another, and tests hypotheses concerning two salient themes of the Green Revolution: farm size differences and the role of information in farmer-to-farmer seed diffusion. Findings indicate that the time span between changing varieties averages only four years, but is shorter on larger farms. Factors that speed variety change also differ by farm size. Extension and media sources of information are significant among larger farmers relative to social information, which is more important among marginal farmers. Traits related to consumption quality speed variety change among smaller-scale farmers, who both sell and consume their wheat. Higher yields drive variety change among the most subsistence-oriented, marginal farmers. |
