Abstract We apply Frąckiewicz's scheme to investigate a quantum Stackelberg duopoly game with isoelastic demand function and unequal marginal costs. We analyze the existence conditions of quantum equilibrium, and the influences of relative marginal cost (m) and degree of quantum entanglement (γ) on the optimal profits and the first-mover advantage in theory. We demonstrate the theoretical analysis by numerical simulations. The results show that an increase of m will increase one player's profit, but will decrease the other player's profit for any fixed γ. An increase of γ will increase both players' profits for any fixed m. An increase of γ will enhance the first-mover advantage for 0 m 1 , but will suppress it for 1 m 2 .

具有等弹性需求函数的量子 Stackelberg 双头垄断博弈

摘要 我们应用 Frąckiewicz 的方案来研究具有等弹性需求函数和不等边际成本的量子 Stackelberg 双头垄断博弈。我们从理论上分析了量子均衡的存在条件,以及相对边际成本(m)和量子纠缠度(γ)对最优利润和先发优势的影响。我们通过数值模拟证明了理论分析。结果表明,m 的增加将增加一个参与者的利润,但对于任何固定的 γ 都会减少另一个参与者的利润。对于任何固定的 m,γ 的增加将增加两个参与者的利润。γ 的增加将增强 0 m 1 的先发优势,但会抑制 1 m 2 的先发优势。
