Leonard Read explained what he called the “white magic” of the market process in his justly praised article “I, Pencil.” No one knows how to make an ordinary pencil; no one can ever know how to make a pencil. And yet pencils are produced in such huge quantities that they are virtually free for the taking. We have pencils not because some one person planned from the beginning the cutting of cedar trees, the mining of graphite, alumina, and bauxite, the extraction of petroleum and clay, or the organization of transportation to get supplies to pencil factories and pencils to retailers. When you contemplate the enormousness of all the tasks that are required to make a single pencil, you understand that no one can know how to do more than a tiny fraction of these tasks.
We have pencils (along with indoor plumbing, electric lighting, microprocessors, disposable diapers, camcorders, concert halls, …) only because for each of the countless tasks required for the production and distribution of each good there are a few people who specialize in knowing how to perform these tasks. But no one knows — or can know — how to perform all of the tasks required to produce even the most commonplace of goods. The free market works as well as it does because, when property rights are respected and fully transferrable, the resulting prices tell each of the producers at the innumerable different production “sites” just what (and how much) to produce and with what particular combination of resources.
For example, if the supply of crude oil falls, the resulting higher price will prompt manufacturers of paint to produce less petroleum-based paints and more linseed-oil or water-based paint. The resulting higher price of petroleum-based paints will prompt pencil manufacturers to paint fewer of their pencils with petroleum-based paints and more of their pencils with paints made of substances other than petroleum. As F. A. Hayek taught, the pencil manufacturer need never know why the price of petroleum-based paint rose; all that is required for this manufacturer to act appropriately is for him to conserve on his use of petroleum-based paint. The higher price of such paint achieves this goal.
