Since what goes around comes around, my work from a few years back on the private sector response to Hurricane Katrina is of relevance again.  Here are the two scholarly pieces for folks who might be interested:

“Wal-Mart to the Rescue:  Private Enterprise’s Response to Hurricane Katrina,” The Independent Review, 13 (4), Spring 2009, pp. 511-28.

“Doing the Right Things: The Private Sector Response to Hurricane Katrina as a Case Study in the Bourgeois Virtues,” in Accepting the Invisible Hand: Market-Based Approaches to Social Economic Problems, Mark D. White, ed., Palgrave Macmillan, 2010, pp. 169-90.
