Social Cohesion Bleg

Tyler Cowen has a nice article about Putnam on his faculty page.

Thanks, Will!

There's the social capital literature; start at this website (in particular this reading list and especially this paper). "Trust" does well in cross-country growth regressions, but Putnam's measures of group membership don't perform well.

Also, I don't know anyone who has studied this formally, but its evident from the U.S. that growth hasn't suffered while formal group membership (by Putnam's reckoning) has declined.
