Quantum Stackelberg duopoly

We apply Li et al.'s 'minimal' quantization rules [Phys. Lett. A 306 (2002) 73] to investigate the quantum version of the Stackelberg duopoly, especially how the quantum entanglement affects the first-mover advantage in the Stackelberg duopoly. It is found that while positive entanglement enhances the first-mover advantage beyond the classical limit, the advantage is dramatically suppressed by negative entanglement
