Game Theory

Game Theory
First published Sat Jan 25, 1997; substantive revision Wed May 5, 2010 Game theory is the study of the ways in which strategic interactions among economic agents produce outcomes with respect to the preferences (or utilities) of those agents, where the outcomes in question might have been intended by none of the agents. The meaning of this statement will not be clear to the non-expert until each of the italicized words and phrases has been explained and featured in some examples. Doing this will be the main business of this article. First, however, we provide some historical and philosophical context in order to motivate the reader for the technical work ahead. 1. The mathematical theory of games was invented by John von Neumann and Oskar Morgenstern (1944). Despite the fact that game theory has been rendered mathematically and logically systematic only since 1944, game-theoretic insights can be found among commentators going back to ancient times. 2. 2.1 Utility

7 Lessons From 7 Great Minds Have you ever wished you could go back in time and have a conversation with one of the greatest minds in history? Well, you can’t sorry, they’re dead. Unless of course you’re clairaudient, be my guest. But for the rest of us, we can still refer to the words they left behind.

Normal-form game In static games of complete, perfect information, a normal-form representation of a game is a specification of players' strategy spaces and payoff functions. A strategy space for a player is the set of all strategies available to that player, whereas a strategy is a complete plan of action for every stage of the game, regardless of whether that stage actually arises in play. A payoff function for a player is a mapping from the cross-product of players' strategy spaces to that player's set of payoffs (normally the set of real numbers, where the number represents a cardinal or ordinal utility—often cardinal in the normal-form representation) of a player, i.e. the payoff function of a player takes as its input a strategy profile (that is a specification of strategies for every player) and yields a representation of payoff as its output.

Seven Blunders of the World The Seven Social Sins, sometimes called the Seven Blunders of the World, is a list that Mohandas Karamchand Gandhi published in his weekly newspaper Young India on October 22, 1925.[1] Later, he gave this same list to his grandson Arun Gandhi, written on a piece of paper, on their final day together, shortly before his assassination.[2] The seven sins or blunders are: History and influence[edit] Mahatma Gandhi, who published the list in 1925 as a list of "Seven Social Sins" (1940s photo) The list was first published by Mohandas Karamchand Gandhi in his weekly newspaper Young India on October 22, 1925.[1] Gandhi wrote that a correspondent who he called a "fair friend" had sent the list: "The... fair friend wants readers of Young India to know, if they do not already, the following seven social sins,"[1] (the list was then provided). In the decades since its first publication, the list has been widely cited and/or discussed.

SCHOPENHAUER'S 38 STRATAGEMS Arthur Schopenhauer (1788-1860), was a brilliant German philosopher. These 38 Stratagems are excerpts from "The Art of Controversy", first translated into English and published in 1896. Carry your opponent's proposition beyond its natural limits; exaggerate it. The more general your opponent's statement becomes, the more objections you can find against it. The more restricted and narrow his or her propositions remain, the easier they are to defend by him or her. Use different meanings of your opponent's words to refute his or her argument. "It's Hard to Have Original Ideas When Everyone Around You Is the Same" This is absolutely true. I love starting up creating projects with a group of varied people. The input everyone gives and the environment that this kind of thing can create is pretty incredible. The hardest part is making sure you find the right people. Oddly enough, communication between different people is what causes this.

Einstein on Kindness, Our Shared Existence, and Life's Highest Ideals by Maria Popova “Without the sense of fellowship with men of like mind… life would have seemed to me empty.” In times of turmoil, I often turn to one of my existential pillars of comfort: Albert Einstein’s Ideas and Opinions — the definitive collection of the great thinker’s essays on everything from science and religion to government to human nature, gathered under the supervision of Einstein himself.

Bayesian game In game theory, a Bayesian game is one in which information about characteristics of the other players (i.e. payoffs) is incomplete. Following John C. Harsanyi's framework,[1] a Bayesian game can be modelled by introducing Nature as a player in a game. Nature assigns a random variable to each player which could take values of types for each player and associating probabilities or a probability density function with those types (in the course of the game, nature randomly chooses a type for each player according to the probability distribution across each player's type space). Harsanyi's approach to modelling a Bayesian game in such a way allows games of incomplete information to become games of imperfect information (in which the history of the game is not available to all players).
