Final answer:
The statement about Garrett Hardin's introduction of 'mutual coercion' in 1968 to help the common good is true. This concept is used to encourage collective behavior that benefits the public good without the need for legal enforcement, thus addressing collective action problems like the 'free rider' issue.
Step-by-step explanation:
Garrett Hardin's 1968 paper, 'The Tragedy of the Commons', does introduce the concept of 'mutual coercion' as a means to solving the collective action problem, affirming the statement as true. 'Mutual coercion' refers to the idea that individuals could be socially compelled to act in ways that are beneficial to public interest or the common good. This is achieved through mechanisms such as social pressure and personal appeals rather than legal force. This concept is particularly relevant when dealing with public goods and ensuring that the benefits provided are not diminished by individual self-interest, which can lead to adverse outcomes such as the depletion of resources.
These mechanisms are exemplified when neighbors form associations for community projects, farmers in low-income countries collaborate on large irrigation projects, and fundraising efforts are made for local charities. Even in the absence of enforceable laws, the collective behavior encouraged by 'mutual coercion' can be critical in achieving positive outcomes for public goods and reducing the 'free rider' phenomenon where individuals benefit without contributing.
