Through my odd traverse through economics education, I admittedly haven't gotten into Dependency Theory. This past weekend, I decided to finally look into it. In general, I'm rather impressed. As an anarchist, I generally appreciate any theory which takes as its foundation relationships of power in thinking through social and political relations.
This paper by Matias Vernengo provides a great introduction to dependency theory. Vernengo, who maintains the blog Naked Keynesianism, outlines the development of Dependency Theory through the scholarship of primarily Latin American and US American neo-Marxist and structuralist thought.
