Early Austrian Economics and The Austrian Case for the Free Market Process

These excellent audiobooks are available from Audible.com. The first one, Early Austrian Economics, features Carl Menger (1840-1921) and Eugen von Bohm-Bawerk (1851-1914) rejecting the classical and Marxian ideas that value can be measured objectively rather than subjectively.

The second audiobook, The Austrian Case for the Free Market Process, features Ludwig von Mises (1881-1973) and Friedrich Hayek (1899-1992) who were perhaps the foremost defenders of the free market and limited government during the mid-twentieth century ascendancy of Keynesian economics.
