Outside the firm, price movements direct production, which is co-ordinated through a series of exchange transactions on the market. Within a firm, these market transactions are eliminated and in place of the complicated market structure with exchange transactions is substituted the entrepreneur-co-ordinator, who directs production.

If economists wished to study the horse, they wouldn’t go and look at horses. They’d sit in their studies and say to themselves, "what would I do if I were a horse?"

I hate when people ask me to: "Massage the data".

We must first note that economic factors are taken into account in a world in which ignorance, prejudice, and mental confusion, encouraged rather than dispelled by the political organization, exert a strong influence on policy making.

Economics, over the years, has become more and more abstract and divorced from events in the real world. Economists, by and large, do not study the workings of the actual economic system. They theorize about it. As Ely Devons, an English economist, once said in a meeting: 'If economists wanted to study the horse, they wouldn't go around and look at horses. They'd sit in their studies and say to themselves, `What would I do if I were a horse?' '

A firm, therefore, consists of the system of relationships which comes into existence when the direction of resources is dependent on an entrepreneur... As a firm gets larger, there may be decreasing returns to the entrepreneur function, that is, the costs of organising additional transactions within the firm may rise.

In fact, a large part of what we think of as economic activity is designed to accomplish what high transaction costs would otherwise prevent or to reduce transaction costs so that individuals can negotiate freely and we can take advantage of that diffused knowledge of which Friedrich Hayek has told us.
