Let them eat risk? Wealth, rights and disaster vulnerability.

Disaster-vulnerability reduction is an impure public good: when provided to one it is provided to others, but not equally provided to all.

This essay distinguishes between two broad classes of approaches to the latter question, one based on wealth, the other on rights.
