I am looking for material for my economics courses, which I am trying to make more heterodox. I would be very grateful if people could steer me to introductory articles of say 20 pages on each major heterodox school: behavioral, ecological, evolutionary-institutional, feminist, humanistic, Marxist/Marxian, post-Keynesian, postmodern, rhetorical, social, socio-, etc. Is there a collection of these?
Failing that, what are the best survey textbooks (if any) suitable as supplements for such classes?
