Suppose Erie Textiles can dispose of its waste "for free" by dumping it into a nearby
river. While the firm benefits from dumping waste into the river, the waste reduces the
fish and bird reproduction. This causes damage to local fishermen and bird watchers. At
a cost, Erie Textiles can filter out the toxins, in which case local fishermen and bird
watchers will not suffer any damage. The relevant gains (in thousands of dollars) and
losses for the three parties are listed below.
Refer to the information given above. If all three parties can communicate and negotiate
with each other at no cost, will Erie Textiles use a filter?
A. No, because it makes $200 less in profit with the filter.
B. Yes, because the benefit it would receive from being able to advertise that it acts in
an environmentally responsible way exceeds the cost of using a filter.
C. No, because use of a filter would result in smaller total economic surplus.
D. Yes, because fishermen and bird watchers are willing to pay enough to Erie Textiles
to offset the cost of using a filter.
