Everywhere, one hears about shortages. Not enough trucks to pick up goods at ports. Six-month waits for appliances. Car dealers with empty lots. Grocery shelves with missing goods. Book releases postponed because of lack of paper and printing facilities.
None of that is supposed to happen. When you have an adverse supply shock, prices are supposed to rise to clear markets. Even if a higher price does not summon more supply, it serves to ration demand. A shortage, where people have to wait or the quantity is rationed, only takes place when the price is artificially held down.
Why are markets not clearing? More remarkably, why aren’t economists talking about it?
The best explanation this economist can offer is that firms do not want to raise prices because they are afraid of blame. If you walk into a store and the price has gone way up, you blame the owners and managers, because the store has discretion over the price. But if the store runs out the stuff, a typical customer will think, “They couldn’t help it. It’s a supply shortage.”
Of course, if you had internalized freshman econ, you would not blame the store for high prices, because the the price comes from market supply and demand conditions. And you would blame the store for being out of stuff and thereby making you wait or else run all over town trying to find stuff. They are just as responsible for setting their price too low. But because most customers have not internalized freshman econ, stores think they will have better customer relations if they run out of stuff than if they raise prices.
If this is the explanation, then I think that the price stickiness will not last forever. Over time, firms will gradually raise prices. I believe that what we are seeing right now is a considerable amount of repressed inflation, and it won’t stay repressed for much longer. By the end of next year, I predict that “shortages” will have been replaced by higher prices.
