The best general source is the History of Economic Thought (HET) Website run by the New School of Social Research in NYC. Unfortunately the site does not permit direct hyperlinks to all articles. Accordingly page directions from their Home Page are provided for each article referenced below. For any investigation at least three different sources should be consulted.
- Economic Schools of Thought
HET - Schools of Thought: Neoclassical Continental - Austrian
HET - The Mercantilists
HET - Marxian School
HET - Monetarists
