 What is a social relationship? A’s social relatedness to B, first of all, seems to require strategic relatedness, in the sense that what B is likely to do is a function, at least in part, of what A does. To get from social relatedness to domination has other requirements. It is difficult to see how A could dominate B unless A has more power over B than B has over A within their social relationship. Further, for A to have power over B plausibly requires that B cannot easily exit the relationship. If someone can easily get a new job just as good as the one they have already, their “exit costs” are low, and they will have a correspondingly low dependence on the social relationship—probably too low for domination to occur (Lovett 2010). It may be that A’s power over B, and B’s exit costs from their social relationship, are not really separate conditions, that A’s power over B is a function of A’s control of resources B cannot access except through A (see Pansardi 2013).
