Suppose electricity generates a negative externality in production. if so, then

(a) the marginal social cost of electricity equals the marginal private cost.
(b) the marginal social cost of electricity is less than the marginal private cost.
(c) the marginal social cost of electricity is greater than the marginal private cost.
(d) the marginal social cost of electricity equals the marginal social benefit.
(e) the marginal social benefit of electricity is less than the marginal private benefit.

The correct answer is option A.

Explanation:

A negative externality refers to the situation when the cost of production is borne by a third party which is not involved in the production process.

In case there is a negative externality present, the marginal social cost will be greater than the marginal private cost. The competitive price will be lower than the socially optimal price.

Since a third party partially bears the cost, the producer will be able to produce more than the optimal level. There will be a deadweight loss of social welfare.

a recipe serves 8 people, and calls for 5 lbs of apples and 2 cups of flour. you want to prepare it for 24 people. divide 24 by 8 to get 3, and then multiply your ingredients by 3.

so for 24 people, you'll need 15 lbs of apples, and 6 cups of flour.

answer: a. the kind of population living in your neighbourhood.

the census explorer data tool by the us census bureau allows the user to zoom in on any neighbourhood within the united states and find the kind of people residing in that by race and age.  

the tool needs to needs to be used twice – once in order to find what type of people reside in a neighbourhood, and then to see the age groups of the people in the same neighbourhood.
