"[I]t is especially surprising that the discussion about externality in the literature of welfare economics has been centered on the external costs expected to result from *private* action of individuals or firms. To our knowledge littler or nothing has been said about the *external* costs imposed on the individual by *collective* action. Yet the existence of such external costs is inherent in the operation of any collective decision-making rule other than that of unanimity. Indeed, the essence of the collective-choice making process under majority voting rules is the fact that the minority of voters are forced to accede to actions which they cannot prevent and for which they cannot claim compensation for damages resulting. Note that this is precisely the definition previously given for externality."

"Much political discussion seems to have proceeded as follows: 'If the interests of two or more individuals conflict, unanimity is impossible. Some interests must prevail over others if action is not to be wholly stifled.' This line of reasoning seems quite plausible until one confronts ordinary economic exchange. Note that in such an exchange the interests of the two contracting parties clearly conflict. Yet unanimity is reached. Contracts are made; bargains are struck without the introduction of explicit or implicit coercion. In this case, no interest prevails over the other; both interests are furthered. Our continued repetition of this simple analogy stems from our conviction that, at base, it is the failure to grasp fully the significance of this point that has retarded progress in political theory."

"When economic or market activity is observed to result in the imposition of costs on parties outside the exchange relationship, economists have tended to call attention to the 'inefficiency' in over-all resource usage that this organizational arrangement generates. They seem rarely to have brought into question the morality or ethics of the individuals participating in such activity. Individuals are assumed to seek to maximize their own utility within the limits of the effective constraints imposed on their action. Not bringing the underlying motivational assumptions into question, the economist tends, therefore, more or less automatically to think in terms of modifying the set of constraints on individual action (the redefining of property rights, the changes in the legal structure, etc.) with a view toward eliminating the inefficiencies, if possible.
"By contrast, the student of political processes, observing what is essentially the same phenomenon in another form (that is, the imposition of external costs on third parties), has not considered the inefficiency aspects seriously. Instead he has - through his emphasis on moral restraints on self-interest, his concept of the 'public interest,' etc. - sought to accomplish reform through a regeneration of individual motives. Ethical and not structural reforms tend to be emphasized. Breakdowns and failures in teh operation of the system are attributed to 'bad' men, not to the rules that constrain them."

"The activities and the importance of special-interest groups in the political process are not independent of either the over-all size or the composition of the governmental budget. A hypothesis explaining the increasing importance of the pressure group over the last half century need not rest on the presumption of a decline in the public morality. A far simpler and much more acceptable hypothesis is that interest-group activity, measured in terms of organizational costs, is a direct function of the 'profits' expected from the political process by functional groups. In an era when the whole of governmental activity was sharply limited and when the activities that were collectivized exerted a general impact over substantially all individuals and groups, the relative absence of organized special interests is readily explainable. However, as the importance of the public sector has increased relative to the private sector, and as this expansion has taken the form of an increasingly differential or discriminatory impact on the separate and identifiable groups of the population, the increased investment in organization aimed at securing differential gains by political means is a
predictable result.
"This relationship is not, however, one-sided. While the profitability of investment in organization is a direct function of the size of the total public sector and an inverse function of the “generality” of the government budget, both the size and the composition of the budget depend, in turn, on the amount of investment in political organization. The organized pressure group thus arises because differential advantages are expected to be secured through the political process, and, in turn, differential advantages for particular groups are produced because of the existence of organized activity. A spiral effect comes into play here, the results of which may be observed in the federal income-tax structure, federal tariff legislation, federal resource-development projects, and many other important areas of economic legislation in particular."
