THE ECONOMICS OF TIME AND IGNORANCE by Gerald P. O'Driscoll, Jr. and Mario J. Rizzo New York: Basil Blackwell, 1985. 261pp., $34.95 O'Driscoll and Rizzo, two leading exponents of the Austrian subjectivist school of economics, claim to provide an original and powerful challenge to mainstream neoclassical economics. They also argue that there is much common ground between the Austrian approach and the recent development of Post Keynesian analysis. In this essay, the validity of such claims is analyzed, and the shortcomings (...) of the Austrian school's approach vis?à?vis Post Keynesian and neoclassical analysis is developed. (shrink)
