It is a great advantage to know the upper and lower limits of a ZOPA. It is understandable that a negotiator is reluctant to take a step forward, or ultimately, because it is the least attractive activity they would accept before moving away from the negotiations. If you know the limits of a ZOPA, it is possible to bring your opponent closer to his limits to get an advantageous deal. A negative trading area can be overcome by “cake enlargement.” In integration negotiations, when it comes to a large number of issues and interests, parties who associate interests with value creation enter into a much more rewarding agreement. Behind each position, there are generally more common interests than opposing interests. [4] Take for example the sale of a used car. The buyer hopes to buy a vehicle at a price between 2,500 and 3,000 $US. The seller is willing to sell for between 2,750 and 3,250 $US. In this scenario, there is a positive trading area between $2,750 and $3,000, in which the buyer and the seller`s terms and conditions can be met. The Concept Zone of a Possible Agreement (ZOPA), also known as the Zone of Potential Agreement [1] or bargaining margin[2], describes the range of options available to two parties in the sale and negotiations when the respective minimum objectives of the parties overlap.

Where there is a ZOPA, an agreement within the area is reasonable for both parties.

Outside the zone, no trading volume should result in an agreement. Consider this example of the anchoring of Harvard Business School Bias and Harvard Law School, Guhan Subramanian. While conducting a negotiation simulation in one of his classes, Subramanian noticed that a student spent a lot of time explaining why $10.69 an hour would be an impossible salary to offer something to the student`s equivalent. That`s right. Read more Negotiations are complex, with many factors contributing to the end result, but they don`t need to be a horrific experience. A good preparation and understanding of the main negotiating concepts and strategies can help you get maximum benefits in the agreements you conclude. This really helped, but I`d be happy if you could help me with a full document on zopa (possible or potential agreement area). Thank you very much. In business negotiations, two polar errors are common: reaching an agreement if it was not wise to do so, and moving away from a mutually beneficial outcome. How can you avoid these pitfalls? By careful preparation that includes an analysis of the area of the potential agreement or zopa in trade negotiations. …
