Start with [link|http://www.cl.cam.ac.uk/ftp/users/rja14/econ.pdf|http://www.cl.cam.ac...rs/rja14/econ.pdf] and work your way through it. Lots of stuff about why companies act as they do, with random useful insights about other things.
For instance from there I found [link|http://www.cato.org/pubs/pas/pa335.pdf|http://www.cato.org/pubs/pas/pa335.pdf], which explains why people drive SUVs so badly...
