I expect that ethical codes and informal nonprice organizations will continue to evolve where needed, for example in the control of product quality, to permit transactions which would be impossible because of differential information in markets where all individuals behaved in a purely selfish manner. The evolution of ethical codes is facilitated by the fact that productive units are organizations, not individuals, and individuals are mobile among these organizations.

There are many other organizations beside the government and the firm. But all of them, whether political party or revolutionary movement, university or church, share the common characteristics of the need for collective action and the allocation of resources through nonmarket methods.

The fundamental fact which causes the need for discussing public values at all is that all significant actions involve joint participation of many individuals. Even the apparently simplest act of individual decision involves the participation of a whole society.
It is important to note that this observation tells us all non-trivial actions are essentially the property of society as a whole, not of individuals. It is quite customary to think of each individual as being able to undertake actions on his own (e.g., decisions of consumption, produc- tion, and exchange, moving from place to place, forming and dissolving families). Formally, a social action is then taken to be the resultant of all individual actions. In other words, any social action is thought of as being factored into a sequence of individual actions.
