The idea is, show the bid/ask spread for time. Workers are selling time, companies are buying it. Of course, broad categories of jobs will be separated from each other.
A bid ask spread looks like this:

There are a few complications: 1. Employers don’t want to share their bid. Well, the law might require them to.
2. Workers might have variable ask. Fair, since it matters if they have to commute and what the role is exactly. That can potentially be countered with a formula. (I’m willing to commute X minutes for Y more dollars per hour, I’m willing to relocate for Z more dollars where Z could be infinity, etc)
3. Jobs are variable and people are variable so time is hard to price. This is true but maybe a close match is good enough to merit an interview.
Bid/ask spreads make sense to me only in situations when fungible units of A are traded for fungible units of B.
Few years ago, I've spent large amount of time, to figure out, why there are so few good films.
Findings shocked me. So simple, but impossible to fix. Just people are unreliable, in sense, You could have best crew, enough budget, best etc, but still deliver something average. And people are most unreliable part of formula. This is not intentionally, just too sophisticated model, accepts too many outcomes, and many leads to fail.
