How do you measure power?
Definitions are as follows: so I would assume that you can "measure" the power by how much profit each obtain in setting their prices??

"Monopoly power" is the degree of power held by the seller to set the price for s specific good/product/service.

"Monopsony power" means there's an exitence of one buyer (or very few buyers) forcing sellers to accept a lower price.
