The reason a market works in the first place is that prices are supposed to deliver all the information we need. When you sit down in a restaurant to order wild-caught salmon, you don’t need to know whether this is the right season for salmon fishing in Alaska, whether the seas have been rough or the trip to the harbor was particularly difficult, or whether the chef is having financial problems. You simply look at the price and make your choice based on that, which should already incorporate all these factors into one number.
