What Prices Can Tell Us

Written by Studio AM.

Consider tin used in solder for joining metal parts. Suppose a mine closes, reducing supply, and the price of tin rises. Manufacturers may economize by using less, recovering scrap or choosing suitable substitutes. They can respond to the higher price without knowing the details of the mine closure.

This example illustrates an argument associated with economist Friedrich Hayek: prices can help coordinate decisions when relevant knowledge is spread among many people. A manager knows which machine is idle; a repairer knows which substitute will work. Some of this knowledge is tacit, developed through practice and difficult to put fully into words. No single report contains every local circumstance.

The price signal also has limits. A product's price may not reflect costs imposed on people outside the transaction, such as harm from pollution that the producer is not required to pay for. Higher prices also reflect ability to pay, not simply how urgently someone needs a good.

Prices are therefore useful information, not a complete account of social costs or needs. Assessing a market requires asking both what its prices encourage people to do and what those prices leave out.
