Austrian and Marxist Theories of Monopoly Capital: A Mutualist Synthesis by Kevin Carson
This is a precursor to Carson's "Studies in Mutualist Political Economy." Carson offers an economic analysis that combines both Marxist class theories and Austrian-based theories on the control of capital.
From the author:
Following the economic arguments of Benjamin Tucker and other mutualists, I distinguish capitalism from a genuine free market, and treat the state capitalism of the twentieth century as the natural outgrowth of a system which was statist from its very beginning.
