The city has a campground whose visitors use the river for recreation. The city also has a tannery that dumps industrial waste into the river. This pollutes the river and makes it a less desirable vacation destination. That is, the tannery's waste decreases the campground's economic profit. Suppose that the tannery could clean up its waste before dumping it into the river, which the campground prefers. If the tannery decides to clean up, then the tannery's economic profit is $1,500 per week, and the campground's economic profit is $1,400 per week. If the tannery does not clean up (pollutes) the river, then the tannery's economic profit is $2,000 per week, and the campground's economic profit is $1,000 per week. These figures are summarized in the following table. 1. Total economic profit is highest when the tannery (cleans up/pollutes) the river. 2. Suppose the campground has the property rights to the river. That is, the camparound has the right to a clean (unpolluted) river. In this case, assuming the two firms can bargain at no cost, the tannery will (clean up / pollute) the river and will pay the campground between $ and $ per week. 3. Now, suppose the tannery has the property rights to the river. including the right to pollute it. In this case, assuming the two firms can bargain at no cost, the tannery will (clean up / pollute) the river, and the campground will pay the tannery betweens per week. 4. The campground will make the most profit when the (tannery/ campground) has the propertyright
