    Classic models and strategies: Nash equilibrium: A game in which each player knows the strategies of the other players and cannot gain a higher return by changing his or her own strategy. Potential Games: The payoff function of the player can be mapped to a global potential function, and there must be a Nash equilibrium in potential games. Negative sum, zero-sum, positive-sum game: According to the results of the game, the game can be divided into three basic types: negative sum game, zero-sum game and positive-sum game.

    Game theory, also known as game theory or game theory, is a branch of applied mathematics that deals with the interaction of formulaic incentive structures. The core goal of game theory is to study the cooperation and conflict of intelligent rational decision makers through mathematical models, and to find the method of game equilibrium.

    A Review of Game Theory: The Art of Strategic Decision-Making Game theory is a fascinating field of study that delves into the strategic interactions between rational decision-makers. This branch of applied mathematics has found its way into various domains, including economics, politics, psychology, and even evolutionary biology. As I delved into the depths of this fascinating subject, I was struck by its universal applicability and the profound insights it offers into human behavior. The book I'm reviewing here provides a comprehensive and accessible introduction to the fundamentals of game theory. It begins with a clear explanation of the basic concepts, such as players, strategies, payoffs, and equilibria. This grounding is crucial for understanding the more complex games and strategic situations that are analyzed later in the book. The authors have done a remarkable job of using real-world examples to illustrate the abstract concepts. Whether it's a simple prisoner's dilemma or a more intricate game of economic competition, the explanations are clear and engaging. These examples help bridge the gap between theory and practice, making the subject matter more relatable and meaningful. I was particularly impressed by the section on cooperative games. Here, the authors explore how players can achieve better outcomes by working together, rather than competing against each other. This is a timely reminder of the importance of collaboration and cooperation in today's interconnected world. Overall, this book is an excellent resource for anyone interested in game theory. Whether you're a student of economics, a strategist in the corporate world, or just someone curious about how people make decisions, you'll find plenty of insights and inspiration here. The writing is clear and concise, and the examples are thought-provoking. I highly recommend this book to anyone who wants to deepen their understanding of strategic decision-making.

    “Total quantity being produced is less than would be produced...” 全部笔记(1) 去书内

    生产的总量少于完全竞争条件下的产量,但多于垄断条件下的产量。因此,价格会向相反方向发展垄断情况下价格最高,竞争情况下价格最低,古诺情况下介于两者之间。从生产者的角度来看,古诺均衡比垄断差,但比完全竞争好。从我们这些消费者的角度来看,古诺数量比完全竞争更糟糕,但比垄断更好。唯一的限制是,如果他们生产可口可乐,而你担心你的牙齿,也许你不应该生产那么多。到目前为止,我们所做的就是研究这种经典的,我承认不是世界上最激动人心的游戏,但是博弈论在不完全竞争中的经典应用

    “How does this quantity compare and how do therefore the prices...” 全部笔记(1) 去书内

    数量如何比较,价格如何比较,利润如何与垄断价格和竞争价格相比较?我们知道产量是多少。我们算出来了;在这里。我们知道将要生产的数量。每个公司生产a-c / 3b,有两个这样的公司。所以市场的总生产量是2a-c / 3b。与垄断数量相比如何?垄断量是a-c / 2b竞争量是a-c / b,这在图上。这是a-c / 2b,这是a-c / b,这是古诺纳什均衡下的总产量。它与垄断数量和竞争数量相比如何?有人知道吗?盯着黑板看,哪个更大?

    “Good, so airlines are an example; we've seen that. Where else?...” 全部笔记(1) 去书内

    很好,航空公司就是一个例子;我们已经看到了。藏在哪里了呢?石油可能是一个经典的例子。航空公司就是一个很好的例子。在石油领域,我们都知道在60年代末,70年代初,石油输出国组织的成立就是为了限制主要石油生产国的产量,很快我们就看到其他国家的公司利用这一点开始生产有利可图的石油。那么谁是欧佩克的竞争对手呢?有人知道吗?首先是英国人,英国人,英国人……应该说是苏格兰。不管怎样,英国开始在北海开采石油;拉丁美洲的许多国家开始寻找石油,当然,俄罗斯的石油开始变得非常非常有利可图。因此,有各种原因导致难以维持这种串通协议。一个是有欺骗的动机,另一个是其他公司会进入。

    “Let's be careful. We'll come back to that next time, but right...” 全部笔记(1) 去书内

    我们要小心点。我们下次再讲这个,但现在我们是在数量上竞争。这里没有固定价格,甚至没有命名价格。我们只是在生产可口可乐和百事可乐,为了一个更美好的世界,把它们喷到市场上。这里还有什么问题吗?有一点是错误的假设可口可乐和百事可乐能够签订合同或其他什么来维持联合垄断产出在这个高价格下,这个价格实际上会在行业中产生正利润,因此价格会高于成本。这些公司赚取了所有的利润,你认为这个行业会发生什么?这个行业有很多利润,这个行业会发生什么?对,那个穿蓝衬衫的家伙;这个家伙。

    “Now, in practice, this is not the only problem facing two...” 全部笔记(1) 去书内

    现在,在实践中,这并不是试图生产垄断产出的两家公司面临的唯一问题。在实践中,当企业试图签订这些协议,而不是合同,试图生产联合垄断产出时,还有什么问题呢?所以你可以想象一些公司试图达成协议。我们知道他们不能签署法律协议,但我们还是不考虑这个了。例如,在1900年左右的美国或者更早一点的时候,比如1880年的美国,当时还不清楚写协议限制产量是否违法。所以公司过去确实会写这种协议,但还是会出问题。出了什么问题?所以我们离游戏越来越远,越来越回到现实世界。
