Questions using social cost
Problem 1
Answer and explanation
Modeled social cost is $14 per unit. A $4 charge could make the measured external effect enter the producer’s decision under the assumptions. The packet lacks demand, damage variation, enforcement, and distributional evidence, so it cannot establish optimal output or universal effectiveness. It illustrates a mechanism rather than resolving a real policy dispute.
Add distinct costs.
Identify the incentive mechanism.
State missing information for broader conclusions.
Response criteria
- Explain the relevant institution or economic concept accurately; show correct calculations where needed.
- Connect supplied evidence and stated assumptions to an explained conclusion.
- Compare feasible options and their effects on different people without stereotypes.
- Identify a limitation, tradeoff, uncertainty, or condition that qualifies the conclusion.
Problem 2
Answer and explanation
Social cost is $11 per unit if the measures are distinct and additive. Demand, harm variation, distribution, authority, and enforcement are not supplied, so the total does not establish optimal output or the best instrument.
