If you ask a good freshman student in Economics 101 what is the cause of a shortage, you will get a quick answer, almost but not quite by rote: demand is greater than supply and for some reason, price has not risen so as to stop the shortage. That is it. That is it in a nutshell. Not much more need be said: shortages are caused by prices being too low. End of story.
This semi-automatic answer emanating from basic economics, however, has eluded a bunch of economists who really ought to know better. They ought to know better since they have advanced degrees in this subject.
What is the question they were facing? It was: why is there a labor shortage? They correctly rejected COVID as a causal agent, but instead have resorted to demographics as an explanation: the baby boomers are retiring en masse, and leaving job slots unfulfilled. For example, according to a CBC analysis of the problem: “Boomers are exiting the workforce in droves, leaving more job vacancies than there are people to fill them.”
Instead of pointing to wages (the price of hiring workers) not rising, these economists are looking at demographics. Here is the CBC’s summary of its survey of Canadian economists: “The reason isn’t that there are fewer jobs opening up — remember the help wanted signs? It’s that there are fewer workers available to fill them. And the reason for that, economists say, can be traced back to the post-war baby boom.”
But this has been predicted for years. It has been widely recognized. For example, according to Armine Yalnizyan, an economist and Atkinson Fellow on the Future of Workers, “It’s the slowest-moving train on the planet. It was predictable 60 to 65 years ago, and we have done nothing about it. We knew this transition was going to happen.” Well, if so, why have not wages risen sufficiently or even approximately, so as to obviate this shortage? Just as nature abhors a vacuum, the market abjures shortages. No, we have to dig a little bit deeper to approach an answer.
What, then, is the answer? And, how did government intervention become involved in the story? This can only be speculative, but we must address the issue of why wages did not already rise sufficiently to obviate the obvious demographic contribution to the help wanted ads? One possibility, and this is only a guess, is that not only is the massive boomer retirement easily predictable and thus well known, but so is the fact that it cannot last forever. Soon enough, its effects will lessen. Suppose wages had indeed risen to levels that would have obviated the labor shortage. When the demographic effect started to dissipate, those temporarily high levels of worker compensation would decrease, lest we be presented with the opposite difficulty, a surplus of labor and unemployment.
But which employer wants to lower wages? In our hyper interventionistic economy, that would be deemed exploitative. The many merry Marxists in the country would have a field day lambasting evil profiteering employers. The government would penalize such heartless capitalists.
Food for thought.

I should hope that no good student would say that. The cause of a shortage is that the quantity demanded is great than the quantity supplied at a particular price and that this price cannot rise to the equilibrium level.

Not at all! The analysis of equilibrium price and quantity, and how departures from equilibrium create shortages and surpluses turns on the distinction between demand and quantity demanded, and between supply and quantity supplied.

I think you are too quick to jump to government as being behind the wariness to raise wages. Economists have known* for a long time that even nominal wages are downward sticky, let alone real wages. And you risk low morale if you try to lower wages later, or if you hire new people at higher wages but don’t raise the wages of the existing employees at the same time.
*I think the evidence of this is actually less firm than many economists had assumed, and that total income actually fluctuates quite a lot because so much is not salary based. And indeed, the companies I work with that had been having trouble hiring would do things like a sign-on bonus instead of raising the base wage. I have my first real salaried job in a long time, but even with that kind of job up to 40% of my income is variable from year to year.

When I hear the term shortage, I think of government instituted price and wage controls. Rent control. Union wages. Minimum wage laws. Scarcity is a market function ameliorated by a pricing mechanism that, hopefully, allocates resources.
Looking at a classic supply and demand curves, any government capped price below equilibrium pricing results in supply being less than demand. Hence a non-market
“shortage.”

But why is the current wage too low today but pre-pandemic the same wage was high enough so we didn’t see help wanted signs everywhere? What changed in less than 3 years?

Excellent question, which gets to the cause of the shortage instead of asking why the normal solution isn’t working. If I get an upset stomach I ask what I ate that caused it, not just why the bromide is taking a while to work, in the hopes I can avoid the mistake in the future.

I think you are confusing cause and corrective here. Shortages are caused by quantity demanded being greater than quantity supplied. Shortages are generally corrected by prices increasing until quantity demanded equals quantity supplied.
You are quite correct to ask why it is that prices haven’t adjusted, but you are asking why prices haven’t responded to correct the shortage. A very useful question might be what caused q. demanded to be greater than q. supplied of late; chances are it might be something we are doing, and the problem could be solved simply by no longer causing it.
I wrote a longer reply to Arnold Kling (who quoted you), and figured I would mention it here as well.
