The Gibsons own a house at 39 Willow Street. They have been approached by their neighbors to the east the Parkers who have asked the Gibsons if they would be interested in buying the half-lot that sits between their two homes.

The Parkers purchased this parcel 15 years ago for around $20,000. At that time, the Parkers had asked the Gibsons if they would be interested in buying the land together and perhaps building a tennis court, but the Gibsons declined.

Now things may change. Although the Gibsons are frugal people --Bob is a teacher/coach at the local high school and Jackie is a part-time bookkeeper --they recently came into a modest inheritance from a favorite aunt. They plan to use some of the money to expand their small house. They have already talked to an architect and contractor about alternative plans. Ideally, they would like to build a new kitchen/solarium to the east, but their house sits as close to the existing property line as the zoning allows. Acquiring the half-lot would completely solve this problem. Without the parcel, the Gibsons will have to expand in another direction. Doing so would be more costly and would not produce as attractive a house.

As a result, the Parkers inquiry came as a pleasant surprise. The Gibsons dont want to be exploited on price, of course. In looking at their bank account and their construction alternatives, the Gibsons have set a firm maximum of $40,000 for the half-lot. If the Parkers insist on more, the Gibsons will pass on the deal. They would naturally prefer to pay much less than the $40,000, if possible, as they have plenty other good uses for the money.

1) What is the Gibsons BATNA in their upcoming negotiation with the Parkers?

2) In the negotiation, is it a good idea for the Gibsons to reveal their BATNA? Why (not)?

3) To get a better deal, is it a good idea for the Gibsons to lie about their BATNA? Why (not)?
