Unformatted text preview: TUTORIAL 11 WEEK 12 COMMON RESOURCES AND PROPERTY RIGHTS PUBLIC GOODS AND THEIR FINANCING Reading Text: Ch 12 (pp334 to end of chapter) Ch 13 Ch 12 Review Questions: 7 7 Spending on Christmas presents can become a positional arms race and result in wasteful spending patterns. Families sometimes devise rules and adopt norms which prevent such races occurring. Agreeing to limit spending is one such rule.

Villagers send three instead, because in deciding whether or not to send a llama, each villager ignores the impact of his or her llama’s presence on the other llamas’ fleece quality.

If the land were free, the owner would thus earn \$22 per year by raising one llama per year on it, or \$7 more than she would have earned had she used her \$100 to buy a bond. The price of the land will be bid up until owning the land is no better buy a bond....
