英文文献作者：Zepeda, Lydia
英文文献摘要：
A multinomial logit model is estimated with survey data from California milk producers to test hypotheses of factors affecting adoption of bovine somatotropin. The model is used to forecast adoption rates and to derive implications of adoption patterns on the structure of the California dairy industry.
