Abstract
Equilibrium conditions for the centralized and for the decentralized oligopolistic markets, which can be viewed as a two-sided supply chain network, are defined and determined. Then after, the price of anarchy (PoA) in oligopolistic market is defined and determined. And more, through numerical simulations, sensitivity analysis on equilibrium results for the centralized and for the centralized oligopolistic market is conducted and a wealth of (but may conflicting) insights are brought forth.
