If the production of a good creates an external cost, is the supply curve the same as the marginal social cost or the same as the marginal private cost curve or both?
What will be an ideal response?
The supply curve is always the same as the marginal private cost curve. In the case of an external cost, however, the marginal private cost curve is not the same as the marginal social cost curve. In this case, the supply curve is the same as only the marginal private cost curve and is not the same as the marginal social cost curve.
