Dear Arun,
I am waiting to read about the situations faced by our members , where they created a win-win situation using this theory. Even a new situation which we can brainstorm using this decision making model.
In HR we do get situations like this almost everyday, where both the parties are equally correct , yet strike a balance with rewards. These models help the decision making objective , free of organizational politics. That remains the upside of using the such theories and models.
The downside is the presentation beyond the academical realms. The Nash Equilibrium remains in making the implementation relevant close to the reality.
Here's one research paper which shatters the myth attached to the financial theories and how it failed in the real world. This necessarily shares the bridge that leads to Nash equilibrium, when accurately applied.
