EDIT: this was... 2004/2005 era.
Not really, as in this field that is about halfway through your tenure. Market has certainly shifted a lot in 9 months past.
Either you agree to buy or sell at a certain price, or not. “Value” plays no role in the determination of prices.
There are other meanings of the word "value" in business transactions, but that is probably the most common and fundamental one.
The subjective assessment of the "value of the trade" is then a function of the subject's alternatives, which is usually how much someone else will pay or accept from them.
I find the term utility to be more beneficial than value, due to it being less likely to be confused. As a boss, I would say I value all the employees equally, in human terms. But the employees provide different amounts of utility/$. Although I can see how people use value and utility interchangeably.
I agree that it is a function of the alternatives, but the operative alternative here is not trading. The best way to assess value is that which you lose by taking something away, like taking a player out of a team or a customer out of your book of business
Note that for buying and selling labor, price is not only the amount of currency being exchanged, but will also include things like work schedules, work environments, break time, location, etc. I prefer to think of it as $x per a certain amount of quality of life at work.
