Most striking feature... is the author’s failure to understand the elementary mechanics of the competitive economic organization. - Frank Knight

The Ethics of Competition is a book of Frank H. Knight's writings on a common theme: the problem of social control and its various implications. Knight believed in free economic institutions but was also aware that the competitive economic system could be improved. One of the central figures of neoclassical economics in the twentieth century, Knight pursued a lifelong campaign against irrationalities of nationalism, religious fanaticism, and group conflict, while conceding that these were fundamental orientations of human action that might yet frustrate his own work as an economist. While Knight vigorously defended human freedom and the liberal order, he also was sufficiently moved by the shortcomings of liberalism as to condemn it as rife with abuse.

[In 1932, Lionel Robbins declared economics ‘the science of choice’ (Robbins 1932). In the same year, when students at the University of Chicago opened their social sciences course reader, they read Knight’s response:] Such definitions come too near to saying that economics is the science of things generally, of everything that men are for practical reasons interested in. Such a definition is useless and misleading

In Professor Pigou's study the argument that free enterprise lead to excessive investments in industry having relatively upward-sloping cost curves is developed with the aid of concrete example, the case of two roads; Suppose that between two points there are two highways, one of which is broad enough to accommodate without crowding all the traffic which may care to use it, but is poorly graded and surfaced; while the other is a much better road, but narrow and quite limited in capacity. If a large number of trucks operate between the two termini and are free to choose either of the two routes, they will tend to distribute themselves between the roads in such proportions that the cost per unit of transportation, or effective returns per unit of investment, will be the same for every truck on both routes. As more trucks use the narrower and better road, congestion develops, until at a certain point it becomes equally profitable to use the broader but poorer highway.
