Abmscore: A Heuristic Algorithm For Forming Strategic Coalitions In Agent-Based Simulation, Andrew J. Collins, Gayane Grigoryan

Engineering Management & Systems Engineering Faculty Publications

Integrating human behavior into agent-based models has been challenging due to its diversity. An example is strategic coalition formation, which occurs when an individual decides to collaborate with others because it strategically benefits them, thereby increasing the expected utility of the situation. An algorithm called ABMSCORE was developed to help model strategic coalition formation in agent-based models. The ABMSCORE algorithm employs hedonic games from cooperative game theory and has been applied to various situations, including refugee egress and smallholder farming cooperatives. This paper discusses ABMSCORE, including its mechanism, requirements, limitations, and application. To demonstrate the potential of ABMSCORE, a new …

Intricacies Of Agency: Rational Choice, Behavioral Economics, And Our Normative Commitments, Max Hendrix

Fenwick Scholar Program

This project undertakes a philosophical analysis of the intricacies of agency found in rational choice theory - the mainstream economic theory that agents are fundamentally rational and utilize their rationality to identify and pursue their self-interest. Recent experimental evidence within and outside of economics has cast doubt on the psychological accuracy and predictive prowess of the theory, laying the foundation to discuss the strengths and limitations of the theory as well as the impacts that this paradigm of agency has on our society today. I argue that rational choice theory struggles as a holistic conception of agency both from an …

The Ultimatum Game: An Introduction To Quantitative Literacy In A Social Justice Context, Robert G. Root

Numeracy

The Ultimatum Game is a two-person, multiple-strategy game widely used in the experimental social sciences to demonstrate the human propensity for costly punishment in response to inequitable treatment. The game serves to provide quantitative evidence for a diversity of fairness norms across cultures. The play of the game and its interpretation offer nuanced views of the nature and importance of quantitative literacy. Its use in a writing seminar connecting quantitative literacy and social justice is described.

Counterfactual Conditional Analysis Using The Centipede Game, Ahmed Bilal

CMC Senior Theses

The Backward Induction strategy for the Centipede Game leads us to a counterfactual reasoning paradox, The Centipede Game paradox. The counterfactual reasoning proving the backward induction strategy for the game appears to rely on the players in the game not choosing that very same backward induction strategy. The paradox is a general paradox that applies to backward induction reasoning in sequential, perfect information games. Therefore, the paradox is not only problematic for the Centipede Game, but it also affects counterfactual reasoning solutions in games similar to the Centipede Game. The Centipede Game is a prime illustration of this paradox in …

Cooperation And Reciprocity In Anonymous Interactions: Other-Regarding Preferences And Quasi-Magical Thinking, Gregory Klevans

Theses and Dissertations

In economic experiments, players often demonstrate concerns for the relative payoffs between themselves and other subjects, in addition to their own payoffs. In addition, they appear to do their parts to achieve efficient outcomes, particularly when they are ignorant of the opponent's decision. I present a parsimonious model of other-regarding preferences and quasi-magical thinking that explains such behavior, and I apply it to four games: the prisoner's dilemma, the traveler's dilemma, the ultimatum game, and the trust game.

Does A Better Running Back Mean More Rushing? Game Theory And The Nfl, Eric Lofquist

Honors Scholar Theses

In this paper I attempt to answer the question of whether or not teams in the National Football League (NFL) rush less with a better running back. This seems counterintuitive, but game theory supposes that this is true. Defenses facing a better running back will generally expect the offense to rush more and therefore defend the run more often. The offense, foreseeing the defense’s actions, will choose to pass more to counteract the run defense. This is the basis of the difference between the strategic effect and the direct effect in mixed strategies. The direct effect is when a player …

The Retirement Strategy Of Supreme Court Justices: An Economic Approach, Kayla M. Joyce

Honors Scholar Theses

Previous research has identified strategic behavior in the nomination, confirmation, and retirement processes of the Supreme Court, each independently. This paper analyzes the interaction between the justices, the president, and the Senate in these processes. I constructed a game theoretic model to consider the nomination and approval process of Supreme Court justices and the change in dynamics that might result from an impending election. I hypothesize that sitting justices take into account the party affiliations of the president and the Senate when they are deciding whether it is the optimal time to retire to achieve their own strategic objectives. The …

Rationality Vs Reality: The Dissonance Between Economic Models And Experimental Data, Piotr Broda

College Honors Program

Rationality was not embedded in economic theory from its onset. In fact, the discipline started with a more holistic approach to human nature, incorporating notions of empathy and altruism. It was not until economics progressed and became more concerned with mathematical models and abstract theories that rationality entered the fray. Game theory, developed in the 1940s, established several axioms about human behavior that presented people as perfectly rational economic agents. It was not until behavioral researchers started investigating the question of rationality that the economic worldview was critically challenged. This research was the driving force in the development of behavioral …

Nashbots: How Political Scientists Have Underestimated Human Rationality, And How To Fix It, Daniel Enemark, Mathew D. Mccubbins, Mark Turner

Faculty Scholarship

Political scientists use experiments to test the predictions of game-theoretic models. In a typical experiment, each subject makes choices that determine her own earnings and the earnings of other subjects, with payments corresponding to the utility payoffs of a theoretical game. But social preferences distort the correspondence between a subject’s cash earnings and her subjective utility, and since social preferences vary, anonymously matched subjects cannot know their opponents’ preferences between outcomes, turning many laboratory tasks into games of incomplete information. We reduce the distortion of social preferences by pitting subjects against algorithmic agents (“Nashbots”). Across 11 experimental tasks, subjects facing …

The Effects Of Discrimination In Public Goods Games, Melinda Maroto

Senior Honors Projects

This paper explores the effects of discrimination on people’s willingness to contribution to public goods. The experiment not only attempts to measure the significance of this partiality, but also attempts to shed light on how discrimination affects this willingness to contribute by testing both the feeling of discrimination and the possibility that discrimination leads to lower payouts. Beyond this, the study acts as an opportunity to further connect the thoughts, behaviors, and political tendencies of social groups to their fiscal decisions.

The experiment tests roughly 120 University of Rhode Island students' willingness to contribute to the construction of a public …

Against Game Theory, Gale M. Lucas, Mathew D. Mccubbins, Mark Turner

Faculty Scholarship

People make choices. Often, the outcome depends on choices other people make. What mental steps do people go through when making such choices? Game theory, the most influential model of choice in economics and the social sciences, offers an answer, one based on games of strategy such as chess and checkers: the chooser considers the choices that others will make and makes a choice that will lead to a better outcome for the chooser, given all those choices by other people. It is universally established in the social sciences that classical game theory (even when heavily modified) is bad at …

Crime In Game Theoretic Models: An Exploration Of The Rational Criminal In A Variety Of Frameworks, Benjamin A. Chalmers

Student Scholarship

There is as much contention over the cause of crime as there is about how to solve it, and the two issues are inextricable from one another. While the idea of studying such a deeply social and humanistic issue through the ‘cold lens’ of mathematics may seem unorthodox or even unproductive to the layperson, the practice has become commonplace since Gary Becker’s introduction of the ‘rational criminal’ model in his paper Crime and Punishment: An Economic Approach in 1968. The rational criminal model is a method of explaining the actions of a criminal not by attributing them to an inherent …

Are Individuals Fickle-Minded?, Mathew D. Mccubbins, Mark Turner

Faculty Scholarship

Game theory has been used to model large-scale social events — such as constitutional law, democratic stability, standard setting, gender roles, social movements, communication, markets, the selection of officials by means of elections, coalition formation, resource allocation, distribution of goods, and war — as the aggregate result of individual choices in interdependent decision-making. Game theory in this way assumes methodological individualism. The widespread observation that game theory predictions do not in general match observation has led to many attempts to repair game theory by creating behavioral game theory, which adds corrective terms to the game theoretic predictions in the hope …

Can We Build Behavioral Game Theory?, Gale M. Lucas, Mathew D. Mccubbins, Mark Turner

Faculty Scholarship

The way economists and other social scientists model how people make interdependent decisions is through the theory of games. Psychologists and behavioral economists, however, have established many deviations from the predictions of game theory. In response to these findings, a broad movement has arisen to salvage the core of game theory. Extant models of interdependent decision-making try to improve their explanatory domain by adding some corrective terms or limits. We will make the argument that this approach is misguided. For this approach to work, the deviations would have to be consistent. Drawing in part on our experimental results, we will …

Some Professionals Play Minimax: A Reexamination Of The Minimax Theory In Major League Baseball, Jeffrey Park

CMC Senior Theses

This paper explores the behavior of Major League Baseball pitchers. We analyze the pitching data from 2007-2010 in order to determine whether their actions follow minimax play. We also examine what the OPS statistic tells us about a pitcher's value.

Are Art Students Nicer Than Economics Students? A Discussion Of How Economic Game Theory Predicts That Art And Economics Students Differ In Terms Of Reciprocity, Abigail Claiborne

University Avenue Undergraduate Journal of Economics

Neoclassical economic game theory predicts that a player’s goal is to maximize her income regardless of others. In playing the Ultimatum Game this means that Allocators will allocate the minimum amount and the Responders will accept that amount because something is better than nothing. Economics students behave differently because they self-select into that field already thinking as economists do and while studying economics they adapt their behaviors to economic theory. Therefore it is natural to assume that Economics students will act according to theory and that non-economics students will not. The Smith College study between Art students and Economics students …
