Perhaps, but a shortage indicates that the amount people wish to purchase at the market price exceeds the amount people are willing to sell. If there is truly a shortage for people with characteristics X, then the market compensation is too low for those people. Raising compensation in this instance sends two messages. First, it may induce more people to offer their services over time. Second, it may induce firms to reconsider their structure and needs and find alternative methods to achieve their goals.I wonder if the more accurate claim is that businesses cannot find qualified candidates at the offered compensation.
In my field (software) most companies are looking for exceedingly skilled people which are in chronic short supply. Those who are skilled enough to get a high wage are usually already employed.
If firms are cannot find people with the desired qualifications at the offered compensation, it is a market signal to those firms that their expectations are unrealistic at the offered compensation.
Yea, that's true. But it also may be true that these small businesses simply can't afford to pay more but also can't find the skills they need at what they can afford, meaning supply is not meeting demand. Maybe their expectations should be lower, but maybe lower expectations are not workable solutions. That would be the problem they face.
