Consider a river found in the city of Pittsburgh, and then answer the questions that follow. The city has a water park whose visitors use the river for recreation. The city also has a ketchup factory that dumps industrial waste into the river. This pollutes the river and makes it a less desirable vacation destination. That is, the ketchup factory's waste decreases the water park's economic profit. Suppose that the ketchup factory could use a different production method that involves recycling water. This would reduce the pollution in the river to levels safe for recreation, and the water park would no longer be affected. If the ketchup factory uses the recycling method, then the ketchup factory's economic profit is $1,100 per week, and the water park's economic profit is $2,600 per week. If the ketchup factory does not use the recycling method, then the ketchup factory's economic profit is $1,800 per week, and the water park's economic profit is $1,500 per week. These figures are summarized in the following table. Complete the following table by computing the total profit (the ketchup factory's economic profit and the water park's economic profit combined) with and without recycling. Action No Recycling Recycling Ketchup Factory (Dollars) 1,800 1,100 Profit Water Park (Dollars) 1,500 2,600 Total (Dollars) Total economic profit is highest when the recycling production method is When the ketchup factory uses the recycling method, the water park earns $2,600 - $1,500 = $1,100 more per week than it does with no recycling. Therefore, the water park should be willing to pay up to $1,100 per week for the ketchup factory to recycle water. However, the recycling method decreases the ketchup factory's economic profit by $1,800 - $1,100 = $700 per week. Therefore, the ketchup factory should be willing to use the recycling method if it is compensated with at least $700 per week. Suppose the water park has the property rights to the river. That is, the water park has the right to a clean (unpolluted) river. In this case, assuming the two firms can bargain at no cost, the ketchup factory will the recycling method and will pay the water park per week. Now, suppose the ketchup factory 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 ketchup factory will the recycling method, and the water park will pay the ketchup factory ▼ per week. The ketchup factory will make the most economic profit when
