Realism is one of the dominant schools of thought in international relations theory , theoretically formalising the Realpolitik statesmanship of early modern Europe. Although a highly diverse body of thought, it is unified by the belief that world politics is always and necessarily a field of conflict among actors pursuing power. The theories of realism are contrasted by the cooperative ideals of liberalism. Realists can be divided into three classes based on their view of the essential causes of interstate conflict.

In some respects, game theory is the science of strategy, or at least the optimal decision-making of independent and competing actors in a strategic setting.
The key pioneers of game theory were mathematician John von Neumann and economist Oskar Morgenstern in the s.
Mathematician John Nash is regarded by many as providing the first significant extension of the von Neumann and Morgenstern work. It is assumed players within the game are rational and will strive to maximize their payoffs in the game. The focus of game theory is the game, which serves as a model of an interactive situation among rational players. The key to game theory is that one player's payoff is contingent on the strategy implemented by the other player. The game identifies the players' identities, preferences, and available strategies and how these strategies affect the outcome.
Depending on the model, various other requirements or assumptions may be necessary. Game theory has a wide range of applications, including psychology, evolutionary biology, war, politics, economics, and business. Despite its many advances, game theory is still a young and developing science. According to game theory, the actions and choices of all the participants affect the outcome of each. Any time we have a situation with two or more players that involve known payouts or quantifiable consequences, we can use game theory to help determine the most likely outcomes.
Let's start out by defining a few terms commonly used in the study of game theory:. Nash Equilibrium is an outcome reached that, once achieved, means no player can increase payoff by changing decisions unilaterally. It can also be thought of as "no regrets," in the sense that once a decision is made, the player will have no regrets concerning decisions considering the consequences.
The Nash Equilibrium is reached over time, in most cases. However, once the Nash Equilibrium is reached, it will not be deviated from. After we learn how to find the Nash Equilibrium, take a look at how a unilateral move would affect the situation.
Does it make any sense? It shouldn't, and that's why the Nash Equilibrium is described as "no regrets. However, this usually occurs in games with more complex elements than two choices by two players. In simultaneous games that are repeated over time, one of these multiple equilibria is reached after some trial and error. This scenario of different choices overtime before reaching equilibrium is the most often played out in the business world when two firms are determining prices for highly interchangeable products, such as airfare or soft drinks.
Game theory brought about a revolution in economics by addressing crucial problems in prior mathematical economic models. For instance, neoclassical economics struggled to understand entrepreneurial anticipation and could not handle the imperfect competition.
Game theory turned attention away from steady-state equilibrium toward the market process. In business, game theory is beneficial for modeling competing behaviors between economic agents. Businesses often have several strategic choices that affect their ability to realize economic gain.
For example, businesses may face dilemmas such as whether to retire existing products or develop new ones, lower prices relative to the competition, or employ new marketing strategies. Economists often use game theory to understand oligopoly firm behavior. It helps to predict likely outcomes when firms engage in certain behaviors, such as price-fixing and collusion.
Although there are many types e. Cooperative game theory deals with how coalitions, or cooperative groups, interact when only the payoffs are known. It is a game between coalitions of players rather than between individuals, and it questions how groups form and how they allocate the payoff among players.
Non-cooperative game theory deals with how rational economic agents deal with each other to achieve their own goals. The most common non-cooperative game is the strategic game, in which only the available strategies and the outcomes that result from a combination of choices are listed. A simplistic example of a real-world non-cooperative game is Rock-Paper-Scissors. There are several "games" that game theory analyzes. Below, we will just briefly describe a few of these.
The Prisoner's Dilemma is the most well-known example of game theory. Consider the example of two criminals arrested for a crime. Prosecutors have no hard evidence to convict them. However, to gain a confession, officials remove the prisoners from their solitary cells and question each one in separate chambers. Neither prisoner has the means to communicate with each other.
Officials present four deals, often displayed as a 2 x 2 box. The most favorable strategy is to not confess. However, neither is aware of the other's strategy and without certainty that one will not confess, both will likely confess and receive a five-year prison sentence.
The Nash equilibrium suggests that in a prisoner's dilemma, both players will make the move that is best for them individually but worse for them collectively.
The expression " tit for tat " has been determined to be the optimal strategy for optimizing a prisoner's dilemma. Tit for tat was introduced by Anatol Rapoport, who developed a strategy in which each participant in an iterated prisoner's dilemma follows a course of action consistent with his opponent's previous turn. For example, if provoked, a player subsequently responds with retaliation; if unprovoked, the player cooperates.
The dictator game is closely related to the ultimatum game, in which Player A is given a set amount of money, part of which has to be given to Player B, who can accept or reject the amount given. The worst possible outcome is realized if nobody volunteers.
It is arranged so that if a player passes the stash to his opponent who then takes the stash, the player receives a smaller amount than if he had taken the pot. The centipede game concludes as soon as a player takes the stash, with that player getting the larger portion and the other player getting the smaller portion.
The game has a pre-defined total number of rounds, which are known to each player in advance. The biggest issue with game theory is that, like most other economic models, it relies on the assumption that people are rational actors that are self-interested and utility-maximizing.
Of course, we are social beings who do cooperate and do care about the welfare of others, often at our own expense. Game theory cannot account for the fact that in some situations we may fall into a Nash equilibrium, and other times not, depending on the social context and who the players are.
It is called game theory since the theory tries to understand the strategic actions of two or more "players" in a given situation containing set rules and outcomes. While used in a number of disciplines, game theory is most notably used as a tool within the study of business and economics. The "games" may thus involve how two competitor firms will react to price cuts by the other, if a firm should acquire another, or how traders in a stock market may react to price changes. In theoretic terms, these games may be categorized as similar to prisoner's dilemmas, the dictator game, the hawk-and-dove, and battle of the sexes, among several other variations.
Like many economic models, game theory also contains a set of strict assumptions that must hold for the theory to make good predictions in practice. First, all players are utility-maximizing rational actors that have full information about the game, the rules, and the consequences.
Players are not allowed to communicate or interact with one another. Possible outcomes are not only known in advance but also cannot be changed. The number of players in a game can theoretically be infinite, but most games will be put into the context of only two players. The Nash equilibrium provides the solution concept in a non-cooperative adversarial game.
It is named after John Nash who received the Nobel in for his work. Game theory is largely attributed to the work of mathematician John von Neumann and economist Oskar Morgenstern in the s, and was developed extensively by many other researchers and scholars in the s. It remains an area of active research and applied science to this day. Princeton University Press. Proceedings of the National Academy of Sciences. Behavioral Economics. Business Essentials.

Political science , occasionally called politology , is a discipline of social science which deals with systems of governance , and the analysis of political activities, political thoughts, associated constitutions and political behavior. Political science is generally divided into distinct sub-disciplines, namely domestic politics and government , comparative politics including area studies , international relations , political theory , political economy , political methodology , public administration , public policy. Comparative politics is the science of comparison and teaching of different types of constitutions, political actors, legislature and associated fields, all of them from an intrastate perspective. International relations deals with the interaction between nation-states as well as intergovernmental and transnational organizations. Political theory is more concerned with contributions of various classical and contemporary thinkers and philosophers.
John Ikenberry, The end of liberal international order? These are not happy times for liberal internationalists. No one can be sure how deep the crisis of liberal internationalism runs. However, in what follows, I argue that despite its troubles, liberal internationalism still has a future. The nature of the crisis is surprising.

Все трое замерли. Над ними, опираясь на перила площадки перед своим кабинетом, стоял Стратмор. Какое-то время в здании слышался только неровный гул расположенных далеко внизу генераторов. Сьюзан отчаянно пыталась встретиться взглядом со Стратмором.
