Dear Felix,
In 2008, Octavio Rodriguez has written a new book
"El estructuralismo Latinoamericano" with the
support of Eclac (Siglo XXI editores). In this
book he develops a profound insight in the
history of latinamerican estructuralism (in a
broad sense including dependency theory, Prebish,
etc) and its main features like the theory of terms of trade.
I think it will be useful for your research.
Regards,
Luis Cáceres Artía
