> If you are looking at the players as the companies deciding to poach/not-poach then the payoffs look just like the prisoners dilemma.
Okay, but the problem itself is different. In a classic prisoner's dilemma the players cannot know how the other will decide and so they act in the manner which benefits them the most. When pursuing their interests they both rat out their accomplice, with the ironic outcome that neither avoids punishment.
> But that means that we are happy to see a prisoners dilemma dynamic here, it means that there has to be some type of collusion to make this dynamic happen. Collusion is explicit and detectable.
Okay, but the collusion is why it's not a classic prisoner's dilemma, I would think.
Also, we're not that happy. The collusion means the companies can avoid punishing one another prisoner's dilemma style. Great for the companies but bad for the employees, since "punishment" in this context involves... hiring.
