Under federal laws, firms in many agricultural industries can force all industrymembers to contribute to collective activities such as industry advertising if the majority agrees.Under the Beef Promotion and Research Act, all beef producers must pay a $1 per head fee oncattle sold in the United States. This fee raises $80 million annually, which finances research,educational programs on cattle disease, and collective advertising by the industry. How might industry advertising by the beef industry be considered a public good (non-excludable and non-rival)? Please explain.
