However, competition limits the firm's ability to capture profits. In the simple model presented in this chapter, competition takes an especially stark form.

This imperfect substitutability of resources is due to differences in the skills of labor and to the specialized function of most machinery and many buildings. Thus, when the decision is made to produce more guns and less butter, the resources reallocated to the production of guns are usually less productive. It therefore follows that as...

In the first place, it is not suggested that Menger, if anybody, has to bear the blame for the incompleteness of the subjectivist movement, and there are few pioneers in the history of thought to whom it is given to witness the completion of what they have set in motion. Secondly, I have to confess that I know of no criterion that would permit us to decide whether a movement of thought has reached its 'end' and is...

Some of the factors we have been discussing tend to attract people to air travel, others merely to attract to a particular airline some people who were going to fly anyway. The total demand for airline service was certainly affected by the quantum jump in speed and comfort when the airlines went from piston to jet fleets. And the general level of personal income also affects total demand for air service. But service amenities are another matter very few people will decide to fly to a point...

Our discussion has suggested one reason a large firm may have a lower long-run average cost than a small firm-increasing returns to scale in production. It is tempting to conclude that firms that enjoy lower average cost over time are growing firms with increasing returns to scale. But this need not be true. In some firms, long-run average cost may decline over time because workers and managers absorb new technological information as they become more experienced at their jdbs. As management and...

We cannot analyze long-run supply in the same way, however, because in the long run firms enter and exit the market as the market price changes. This makes it impossible to sum up supply curves-we don't know which firms' supplies to add. To determine long-run supply, we assume all firms have access to the...
