I guess so. Retaliation is the best strategy in iterative PD, no? (I&#x27;m rusty on this stuff).<p>Nash equilibrium in a regular PD would be DD, but it assumes that the other side will defect. I think from experience that the payoff grid is different in business in that instead of CC resulting in a lower payoff for C than for D in CD, it&#x27;s a much higher payoff; and the D in CD is not getting much more than in DD (maybe 20% more).
