I recommend this article by David Friedman on the topic -- if you've never heard of the concept, you'll probably find lots of interesting insight in it:

Friedman uses Schelling points in an attempt to explain the origin of the concept of property rights among humans and the associated legal and social norms, but the approach can be generalized in an obvious way to a much wider class of relations between people (basically anything that could hypothetically lead to a conflict, in the broadest possible sense of the term).
