英文文献摘要：
This study uses revealed preferences of consumers to study the consumer valuations of rBST-free and organic milk. The study specifies and estimates a quadratic AIDS model for different milk types using US supermarket scanner data. The introduction of rBST-free and organic milk is used to estimate both competitive and variety effects as measures of consumer valuations. Results show significant consumer valuations for organic milk and to a lesser extent rBST-free milk.
