摘要：Expenditure patterns for whole milk and lowfat milk in the Northeast region were examined by applying the Tobit maximum likelihood procedure to the 1977-78 USDA NFCSdata. Results suggest that differing expenditure patterns exist between whole milk and lowfat milk. Household income estimates indicate significant positive effects on expenditure for lowfat milk but negative on expenditure for whole milk. Whole milk expenditure was estimated to be strongly related to the family life cycle stages through the child-raising years.
