A group of fishermen and a nearby banana plantation are negotiating a deal to reduce water pollution. Without a deal, the plantation earns $500,000 in profit, and the fishermen earn $200,000. If the plantation reduces its output, its profit falls to $400,000, but the cleaner water increases the fishermen's profit to $350,000. The fishermen agree to pay the plantation their maximum possible offer to convince them to reduce output. What is the final profit for each party after this payment is made?

Evaluating Surplus Distribution in a Negotiation

Consider a negotiation where a group of fishermen offers to pay a nearby factory to reduce its water pollution. If the fishermen agree to pay their maximum possible offer—an amount exactly equal to the total financial benefit they would receive from the cleaner water—then the resulting agreement can be described as Pareto efficient.

Analyzing Surplus Distribution in a Negotiation

Explaining the Outcome of a Negotiation

A chemical factory's operations pollute a river, harming a downstream fishery. The parties are negotiating a deal for the factory to reduce its pollution.

• Without a deal, the factory's profit is $1,000 and the fishery's profit is $500.
• If an agreement is reached, the factory reduces pollution, causing its profit to fall to $800. The cleaner water increases the fishery's profit to $850.
• The total net social gain from this agreement is $150.

Match each potential payment amount from the fishery to the factory with the correct description of how the net social gain is distributed.

A winery's use of a specific pesticide harms a neighboring organic farm, reducing the farm's profit by $50,000. The winery could switch to a different pesticide, which would reduce its own profits by $20,000. The total net social gain from the winery switching pesticides is $30,000. If the organic farm pays the winery its maximum possible offer to convince it to switch, how is the $30,000 net social gain distributed?

A downstream fishery's profits are harmed by an upstream factory's pollution. Without any agreement, the factory earns $10,000 and the fishery earns $20,000. If the factory installs a filter, its profits fall to $8,000, but the fishery's profits rise to $25,000 due to cleaner water. To incentivize the factory, the fishery agrees to pay the factory its maximum possible offer. After the payment is made, the fishery's net gain from the agreement is $____.

Analyzing Surplus Distribution in a Cooperative Agreement

An apple orchard's use of a certain pesticide negatively affects a neighboring beekeeper. The two parties are considering an agreement where the orchard stops using the pesticide.

• Without an agreement, the orchard's profit is $100,000 and the beekeeper's profit is $40,000.
• If the orchard stops using the pesticide, its profit will fall to $85,000, while the beekeeper's profit will rise to $70,000.

Which of the following payment arrangements from the beekeeper to the orchard would result in the orchard capturing the entire net social gain from the agreement?
