Mises’s Law of Association (also called the “Law of Association”) is a principle formulated by Ludwig von Mises in his book Human Action that explains why human beings associate voluntarily and why social cooperation and the division of labor are always advantageous for all participants.
Essential content of the law
Mises generalizes and radicalizes the principle of comparative advantage of David Ricardo (originally applied to international trade) and elevates it to the level of a fundamental praxeological law of human action:
- Even if an individual (or group, or nation) is superior in all productive tasks relative to another, both benefit from the division of labor and from exchange, so long as relative differences in productivity exist.
In other words: association and specialization do not require that one be “better” at something in absolute terms.
It is enough that there be relative differences in the efficiency with which each performs different tasks.
The one who is superior in everything concentrates on that in which his superiority is greatest, and the inferior specializes in that in which his inferiority is least. Both gain.
Implications
- Foundation of society: Social cooperation is not a moral “social contract” or an act of altruism, but the rational result of the pursuit of self-interest under conditions of scarcity and heterogeneity of talents and resources.
- Universality: The law holds for individuals as well as for groups, regions, or nations. It justifies free trade and the international division of labor even among countries with very unequal productivities.
- Rejection of isolationism and productivist egalitarianism: It is not necessary to “protect” the less productive or artificially equalize capacities. Association benefits everyone precisely because capacities are unequal.
- Basis of civilization: According to Mises, the progress of civilization is, to a large extent, the result of the ever greater extension of the division of labor and of voluntary association.
Classic formulation of Mises
In Human Action (especially in the chapters on society and the division of labor), Mises writes that the law of association is “the fundamental law of human cooperation” and that it explains why man, unlike the animals, builds a complex society based on exchange and specialization.
Mises’s Law of Association demonstrates that social cooperation and the free market are not zero-sum, nor do they depend on equality of capacities, but are the necessary and beneficial result of human differences under the logic of rational action.
