I think you can also refer to Labor Theory of Value, which was the basis of classical political economy writings. There is an interesting book called Classical Econophysics that might also be interesting to this topic. My final suggestion is also based on this way of looking what is value from the writings of Karl Marx, making the difference between Value - Exchange value - Use Value. I suggest David Harvey video lecture as a good start point.
Many thanks and I hope this would give another (far-from mainstream) view of this issue.
