I gave a couple of talks on Walmart at Buena Vista University yesterday and promised to post some links relevant to some of the questions people asked. On the importance of private property rights, play the bunny game from the IHS. Here's my Mises Media Archive, with audio of my "Environmental and Resource Economics" lecture. Here's my list of links from a panel at Rhodes; it includes links to Lant Pritchett's excellent book Let Their People Come. I also recommend William Easterly's wonderful The White Man's Burden and C.K. Prahalad's The Fortune at the Bottom of the Pyramid.

Addendum: Here's my paper with Charles Courtemanche and Jeremy Meiners on Walmart and values, available for ungated download from BEPress.
