Principles of Economics ushered in modern economics. Principles not only revolutionized value, price, and marginal utility theories, but it was also used as the primary textbook by several generations of Austrian students and scholars, including Ludwig von Mises and F. A. von Hayek. No economist's library is complete without a copy of this classic work.
