Abstract:
This essay discusses and refutes allegations by A.C. Pigou and R.H. Coase that a competitive, private-ownership economic system that conforms to the neoclassical model fails to allocate resources efficiently. The essay then suggests a source of inefficiency that differs from and is much more limited in application than are those offered by Pigou and Coase; and the suggested source, moreover, is compatible with the neoclassical model.
