render it difficult to do in that way. These all reduce to cases in which strictly voluntary exchange is either exceedingly costly or practically impossible. There are two general classes of such cases: monopoly and similar market imperfections, and neighborhood effects. |

Exchange is truly voluntary only when nearly equivalent alternatives exist. Monopoly implies the absence of alternatives and thereby inhibits effective freedom of exchange. In practice, monopoly frequently, if not generally, arises from government support or from collusive agreements among individuals. With respect to these, the problem is either to avoid governmental fostering of monopoly or to stimulate the effective enforcement of rules such as those embodied in our anti-trust laws. However, monopoly may also arise because it is technically efficient to have a single producer or enterprise. I venture to suggest that such cases are more limited than is supposed but they unquestionably do arise. A simple example is perhaps the provision of telephone services within a community. I shall refer to such cases as "technical" monopoly. |

When technical conditions make a monopoly the natural outcome of competitive market forces, there are only three alternatives that seem available: private monopoly, public monopoly, or public regulation. All three are bad so we must choose among evils. Henry Simons, observing public regulation of monopoly in the United States, found the results so distasteful that he concluded public monopoly would be a lesser evil. Walter Eucken, a noted German liberal, observing public monopoly in German railroads, found the results so distasteful that he concluded public regulation would be a lesser evil. Having learned from both, I reluctantly conclude that, if tolerable, private monopoly may be the least of the evils. |

If society were static so that the conditions which give rise to a technical monopoly were sure to remain, I would have little confidence in this solution. In a rapidly changing society, however, the conditions making for technical monopoly frequently change and I suspect that both public regulation and public monopoly are likely to be less responsive to such changes in conditions, to be less readily capable of elimination, than private monopoly. |
