Here is some more fodder to feed your inner economist.
Cool Economics (website), Michael Williams, Prairie View A&M University.
This quirky website has several economics courses taught by Michael Williams, and a number of short videos featuring a nerdy character called Dr. Nigel Cool who sports big glasses, a bow-tie and speaks in an undefinable accent. The Cool videos introduce some very basic economic concepts and go along with other course materials for introductory econ courses.
Economics for the Citizen (website), Walter Williams, George Mason University.
This series of articles written by Williams in 2005 explains the basics of economics in clear, non-technical language.
