While it's easy to see how a distrust of others may inhibit economic growth, is it possible that "too much trust" can also present problems for economic growth? Here is an interesting paper by Roth examining this question which may provide some interesting discussion.

It is also interesting to see how societies may operate even when trust barriers are either small or non-existent. Below is a very good paper by Peter Leeson which explains how hostile groups along the Anglo-Saxon border were able to come together and trade and cooperate despite being enemies.
