This research program aims at developing game theoretic models for oligopolies where competitive interactions exist between firms operating in a channel. This research program will help identify optimal firms' decisions in different rivalry situations and understand how these decisions are affected by various market and industry conditions. In particular, the results of this research will provide manufacturers and retailers with a better understanding of how their advertising and promotional decisions do affect their payoffs and those of their competitors. Our methodology will be analytical and will consist in developing static and dynamic game theoretic models that represent different scenarios of competition where the effects on payoffs of non-price decision variables are modeled. Game theory allows us to study decisions of distribution channels' members using a system approach. It provides equilibrium solutions for the decisions of several institutions (e.g., retailers and manufacturers) that have interdependent interests but at the same time do maximize their payoffs opportunistically. For most studied situations, non-cooperative games will be considered and Nash and Stackelberg equilibria will be computed. For dynamic games, preference will be for closed-loop and feedback information structures that provide subgame perfect solutions. Our methodology will also involve sensitivity analysis of the obtained equilibria to see how the different model's parameters affect optimal decision strategies. When appropriate, payoffs and equilibria from different scenarios will also be compared to study the effects created by competition. Finally, numerical simulations of the models' parameters will also be conducted to illustrate the sensitivity analysis, the path or the trajectory of the obtained equilibrium strategies.

本研究的目的是建立寡头垄断的博弈论模型，在寡头垄断企业之间存在竞争性互动的渠道。这项研究计划将帮助确定公司在不同竞争情况下的最优决策，并了解这些决策如何受到各种市场和行业条件的影响。特别是，这项研究的结果将使制造商和零售商更好地了解他们的广告和促销决策如何影响他们和他们的竞争对手的收益。我们的方法将是分析性的，将包括开发静态和动态博弈论模型，这些模型代表不同的竞争场景，其中对非价格决策变量对收益的影响进行建模。博弈论使我们能够用系统的方法研究分销渠道成员的决策。它为几个机构(如零售商和制造商)的决策提供了均衡解决方案，这些机构具有相互依存的利益，但同时也确实机会主义地最大化了他们的收益。对于大多数研究的情况，将考虑非合作博弈，并计算Nash和Stackelberg均衡。对于动态游戏，偏好将是提供子博弈完美解决方案的闭环系统和反馈信息结构。我们的方法还包括对所获得的均衡进行敏感性分析，以了解不同模型的参数如何影响最优决策策略。在适当的时候，还将比较不同情景的收益和均衡，以研究竞争所产生的影响。最后，还将对模型参数进行数值模拟，以说明所获得的均衡策略的灵敏度分析、路径或轨迹。
