Institutions are the humanly devised constraints that structure political, economic, and social interactions. They consist of both informal constraints (sanctions, taboos, customs, tradition, and code of conduct) and formal rules (constitutions, laws, property rights).

Karl Marx and Adam Smith both subscribed to this view. They both saw successful growth as dependent on the development of efficient property rights. Their followers appear in the main to have forgotten this.

By that time a structure of property rights had developed in the Netherlands and England which provided the incentives necessary for sustained growth. These included the inducements required to encourage innovation and the consequent industrialization. The industrial revolution was not the source of modern economic growth. It was the outcome of raising the private rate of return on developing new techniques and applying them to the production process.

Information costs are reduced by the existence of large numbers of buyers and sellers. Under these conditions, prices embody the same information that would require large search costs by individual buyers and sellers in the absence of an organized market.
