英语翻译
Buyers and sellers self-select into and out of markets based upon their preferences,their willingness-to-pay,and the cost of production.When the market “clears,” there is no excess demand or excess supply,so no resources are put into storage and no resources are still desired at the prevailing price.This outcome is efficient.Free marketers regard this optimal use of resources as fair.That is what they mean when they say that free trade is fair trade.
