Modeling Fairness in the Ultimatum Game Kevin Dastalfo Advisors: Andrew Belmonte and Chris Griffin
Introduction • Evolutionary Game Theory – What is it? • The Ultimatum Game • Sub-game perfect equilibrium • Factors to explore • Altruistic punishment • Expectations • Complacency with status quo • Envy
Goals • What modeling has been done? What do previous studies tell us? • Assemble, summarize, and formulate conclusions from sets of data • Design an ODE; formulate an approach to modeling
Literature Review • Economic Decision-Making in the Ultimatum Game • Neural activity in proposals and acceptance • Role of emotions in decision making • Human vs. Computer G. Sanfey, J. K. Rilling, J. A. Aronson, L. E. Nystrom, and J. D. Cohen. The neural basis of economic decision-making in the ultimatum game. Science, 300:1755–1758, 2003. • Learning to be Imperfect • Learning – understanding of optimality • Perturbations in the learning process J. Gale, K. G. Binmore, and L. Samuelson. Learning to be imperfect: The ultimatum game. Games Econ. Behav., 8:56–90, 1995.
Future Directions • Formulation of an ODE • Perform an experiment on campus • Analyze data and develop conclusions
