Producer surplus is most accurately defined as the:

A) sum of the differences between the price received for each unit of good produced and the opportunity cost of each unit.

B) difference between the opportunity cost of producing the last unit of a good or service and the price received for that unit.

C) sum of the differences between the marginal benefit and the marginal cost for each unit of good produced and consumed over the total number of units produced and consumed.

---

Producer surplus is the sum of the differences between the price received for each unit of good produced and the opportunity cost of each unit, for the total units produced. Producer surplus results when the market price for a good or service exceeds the marginal cost producing it.

The minimum supply price, the lowest price at which a producer is willing to supply an additional unit of a good, is:

A) the price at which producer surplus is maximized.

B) less than the marginal revenue for the additional unit.

C) the marginal cost of producing the additional unit.

The minimum supply price that producers must receive if they are to produce an additional unit of output is the opportunity cost of producing that unit, i.e., the marginal cost. The marginal cost curve is the short-run supply curve for the good.
