Economists have regarded the market as a decentralized system of resource allocation for a long while. In the market, no one is in charge of allocating resources beyond what every individual has under his or her command. For instance, there is no one centrally deciding whether car makers should produce white cars or whether computer makers should make laptops rather than desktop computers. In such a system, entrepreneurs constantly bid resources away from their current uses in order to reallocate them towards what consumers may want to buy. In the marketplace, resources are bought and sold without anyone deciding what the overall allocation of resources should look like.
