Question
**Policymakers are provided data about the private and social benefits of a good being sold in the market.**

| Quantity | Private MB ($) | Social MB ($) |
|----------|---------------|---------------|
| 4        | 6             | 9             |
| 5        | 4             | 7             |
| 6        | 2             | 5             |
| 7        | 0             | 3             |

**What is the size of the externality? If the externality is positive, enter a positive number. If negative, make it a negative number.**

[_Enter numeric value_]

**Given this data, policymakers must decide whether to address the associated externality with a subsidy or a tax. As their economic consultant, which of the two policy tools would you recommend?**

- a subsidy
- a tax

**Explanation:**

The given table presents the quantities, private marginal benefit (Private MB), and social marginal benefit (Social MB) of a good. To find the size of the externality, calculate the difference between the Social MB and the Private MB for each quantity level. The externality is positive if Social MB > Private MB and negative if Social MB < Private MB.

Policymakers need to decide on using either a subsidy or a tax to align private incentives with social benefits, based on the nature of the externality. If the externality is positive (Social MB > Private MB), a subsidy might be recommended. If negative, a tax might be preferable.
