I just finished reading http://www.amazon.com/exec/obidos/ASIN/0465016154/ which espouses the theory that the root of a lot of problems is that countries set up formal property systems that exclude most of their population, and then fail to capture the contracts that people actually live by. Because of this, people are unable to secure loans because they can't prove to the broader world that "their" property is theirs.
It is a classic, "Here is the problem, fix this and all else gets better" kind of prescription. I'm always suspicious of those.
But as an expert in this area, what do you think of this one? Is it as big an issue as they claim? How much would fixing it help?
