Mandated agricultural commodity promotion programs - such as Got Milk - are highly visible, economically important, and controversial. In recent years, these programs have spent more than $1 billion on generic commodity promotion. They are authorized by producer referenda and funded using mandatory commodity taxes on producers and/or handlers. These programs have been the subject of much dispute and litigation, especially in California, which is home to a large number of them. This book takes a comprehensive look at the economic consequences and the resulting legal implications of commodity promotion programs in California, and distills the key consequences for similar programs on a national scale.
