Right, this is why Shapley value is not the market value.
One could also imagine a world in which A is a software engineer who can make 100k at his day job, but B and C are experts in a little-known, poorly paying, field with the potential to revolutionize the world, and they’re looking for a software engineer to help them build a product. B and C can then offer A 110k, while each pocketing 145k.
Also note that the scenario above is not the scenario I worked out in my original post. If the software engineer makes 120k and the Chilean makes 20k on their own, then the Shapley value is actually
A = 166k
B = 86k
C = 146k
Shapley value != market value, but in many cases, it’s usually fairer than market value.
