The Pros And Cons Of Game Theory

I. Introduction to Game Theory
Originally the theory of games was developed to look at games, applying to games such as chess, checkers, and tic-tac-toe (Owen, 2013). Game theory has not become a standard language in economics and other social sciences but this branch of study was original developed in 1944 by John von Neumann and Oskar Morgenstern. It wasn’t until a few years later that a solution was proposed as to how rationale players would interact. John Nash proposed that players would adjusted their strategies until no player could benefit from changing and reach what has been coined the “Nash Equilibrium.” The equilibrium will leave the players at their best possible response to all other players responses (Camerer, 2003; University

Current day critics of game theory still have many reasons to questions its validity and application in real world situations. The first, and most important critic, is that game theory has very little empirical content and therefore it is very hard to test its validity or the extent to which people will be rational in certain context (Hausman, 2005). Other critics point out that most current models assume that people will only pursue their own self-interest but psychological evidence strongly indicates that people do not always act in their own self-interest. This is especially true when they see others being kind or generous or in an effort to punish others who are being unkind (Rabin, 1993). These many current and past critics have led some to question whether game theory has been refuted and is therefore no longer a viable field of study (Guala, …show more content…
Cooperative games are those where players can make binding agreement with each other and value is added by this cooperation but in noncooperative games, cooperation is impossible to implement or will not have any positive benefit for the individuals (Chalkiadakis, Elkind, & Wooldridge, 2012). A symmetric game is one where the payoffs for playing a particular strategy depend only on the other strategies employed, not on who is playing those strategies. An asymmetric game is one where the identity of the players change the payoffs for each strategy (Schmidt, 2003; Stahl, 1999). A zero-sum game is one where the gains of one player come at the expenses of an exact loss to the other player, whereas in a non-zero-sum game the gains or losses of one player do not cause any gains or losses of the other player (Salvator, 2015). The difference between simultaneous and sequential games is the knowledge of the later players. In a simultaneous game the players either move at the same time or the alter player is not aware of the earlier player’s action. Sequential games on the other hand, are those which the later players have complete knowledge about the earlier player’s action (Bag & Roy, 2011; Seigrist & Steele, 2001; Fershtman,

    Behavioral game theory analyzes strategic decisions and behavior used in experimental economics. Behavioral game theory aims to explain why people do the things they do and how they they learn from their actions. Behavioral game theory is an approach in which you study the cognitive basis of an individual's behavior. Behavioral game theory is useful for explaining what normal people do and how they learn. Behavioral game theory replaces the assumption that people are self interested and that people reach an equilibrium in which everyone is choosing or planning strategies that yield the best outcome, assuming that other players in the game are doing the same.…

    In the social exchange theory, humans are considered to be rational beings. The theory saw that human beings made rational decisions based on the amount of information available to them. With that being said, these decisions are made to receive the greatest reward with the less amount of cost. For example, when the group was deciding what topic to pick for the role play. They use what information they already had available to them.…

    War Play Dilemma Analysis

    These days’ kids have a plenty of different wishes and sadly they have a different ways of playing. Going through the readings from the book called "The War Play Dilemma" by Diane E. Levin and Nancy Carlsson-Paige, I realized that today games are very dangerous, especially war play among children. While reading chapters, we can clearly see how parents and teachers are getting more concern and they are trying to explore what is the reason of that kind of play and they try to find a solution connected to war play. For example, if we take a look on video games, which can be very dangerous; but still children still likes them, and in some cases, parents are spending a lot of money on those video-games and actually they are making a big mistake,…

    In addition, emotions appeared to play an extensive role as the second players still intensively punished the first in the last round. Hence with this variation, little support for the basic rent-seeking model was found. I believe this follows the experiment conducted by Miller and Pratt as discussed by Potters et al. and is similarly skewed as they used sequential decisions rather than a simultaneous single decision design. Overall, Potters et al. succeeded by using an appropriate design to investigate the two starkest cases.…

    The Ultimatum Game describes a situation where there is value, in this case money, where it is offered to someone on the condition that the responder would have an ultimatum to either accept an offer as it is, or reject it, in which case the person making the offer and the responder receive nothing. From the Analysis of offers and responses presented in the table, when the offer is above 50% of the pot It would be safe to assume that the responders perceive as a very good deal and therefore, accept it. This can also suggest that the person making the offer was worried of a rejection which led him/her to give a higher percentage of the pot even more than 50%. However, At $16 to $25, the offer can be perceived as fair. Between $1 to $15, it is…

    Dominant strategies are considered better than other strategies, no matter what other players might do. In addition, the game theory includes two types of strategic dominance. The first, is a strictly dominant strategy always provides greater utility to a player, no matter what the other player’s strategy may be. Secondly, a weakly dominant strategy is that strategy that provides at least the same utility for all other player’s strategies, and strictly greater for some strategy. In college, I played college football for the University of Tennessee at Martin.…

    Cesare Beccaria and Jeremy Bentham were the founders of the classical theory phenomenon (Piliavin, 1986). The concept was based on several principles, which entailed three main ideologies; free will, where actions are based on one’s own rationality (Burke 2014), more so punishment should apply to the crime as opposed to the criminal, as the theorists believed that a certainty in punishment would deter both the public and criminal (Akers 1999). The perspective adopted throughout will focus on the theories inability to justify the actions of violent homicide offenders, such as Jeffrey Dahmer, and how the high recidivism rates fail to support specific deterrence, even when making the punishment fit the crime. Free will assumes that all individuals…

    Mutual cooperation, though it would be the rational choice for both players, is not easily achieved or maintained. In the standard two-person, one-shot game, it appears that the safest option would be to defect, as this would result in either a five-year sentence or no prison at all, while cooperation yields either a one-year sentence or a fifteen-year sentence. Even when playing the game repeatedly, cooperation is improbable in the Prisoner’s Dilemma due to backwards inductive reasoning. The Stag Hunt Game, on the other hand, allows cooperation to be far more stable because when both players cooperate, a Nash equilibrium occurs, so neither player would do better by changing their strategy. Thus, there would be no logic in withdrawing cooperation in the Stag Hunt Game, as this would only serve to harm both players.…

    Utilitarianism is considered as one of the most prominent philosophical concepts. This model's core perspective emphasizes that actions are ethically acceptable or unacceptable depending on their consequences. Based on this understanding, it can be argued that utilitarians hold that the goal of morality is to improve life by enhancing some favorable things such as happiness in the world while minimizing undesirable aspects such as grief (Urmson, 33). Consequently, the core objective of this essay is to define and critique both Act and Rule Utilitarianism, as well as determine the most practical kind of utilitarianism.…
