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

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 …
Victory By The Weakest: Effects Of Negative Advertising In N>2 Candidate Campaigns, Jesse T. Richman
Victory By The Weakest: Effects Of Negative Advertising In N>2 Candidate Campaigns, Jesse T. Richman

The truel, or three way duel, has distinct properties from duels: the weakest contestant often has a very good chance to win. This paper explores application of the logic of truels to election campaigns involving negative advertising. We show that negative campaigning that pits the leading candidates against each other can create circumstances in which the third (or worse) place candidate wins in one or more of the Nash equilibria of the game. We then study whether the simulated existence of an opportunity for Nash equilibrium victory by third place candidates predicts such outcomes in U.S. state-wide elections.

Hedonic games have applications in economics and multi-agent systems where the grouping preferences of an individual is important. Hedonic games look at coalition formation, amongst the players, where players have a preference relation over all the coalition. Hedonic games are also known as coalition formation games, and they are a form of a cooperative game with a non-transferrable utility game. Some examples of hedonic games are stable marriage, stable roommate, and hospital/residence problem. The study of hedonic games is driven by understanding what coalition structures will be stable, i.e., given a coalition structure, no players have an incentive to deviate …
Can The Us And Europe Contain Russian Power In The European Energy Market? A Game Theoretic Approach, Jesse Richman, Nurullah Ayyilmaz
Can The Us And Europe Contain Russian Power In The European Energy Market? A Game Theoretic Approach, Jesse Richman, Nurullah Ayyilmaz

The Russian history of politicization of natural gas supplies led Europe to seek alternatives. US LNG is considered to be a viable alternative for Europe, which positioned the US as a strong competitor against Russia. In a game theoretic approach, we model this strategic decision-making process in simultaneous-move and sequential games. Our findings indicate a mixed strategy equilibrium: Europe cannot commit to diversify in the face of Russian advantages, and Russia cannot fully resist the temptation to politicize its supplies to Europe. The US might attempt to intervene in the European commitment problem through implementing sanctions on Russian gas sales. …
Financing Strategies Of The R & D Firm, Lawrence Fogelberg, John M, Griffith
Financing Strategies Of The R & D Firm, Lawrence Fogelberg, John M, Griffith
Finance Faculty Publications
This paper investigates the financing strategies of the R&D firm. Our hypotheses are based on Cho's (1992) game theory model where the firm develops a product but needs additional financing to bring it to market. The model generates a particularly rich set of hypotheses: 1) to fund the completion of its project and bring its product to market, the firm initiates negotiations with an established firm; 2) the majority of the acquisitions will be partial cash acquisitions through private secondary offerings. Confirming the model's hypotheses, we find that the majority of the acquisitions are partial cash acquisitions by significantly larger …
