“The Behavior of Learning Algorithms in Experimental Games with Congestion,” Job Market Paper
Abstract:Learning algorithms represent an important step in modeling the dynamic behavior of human
subjects observed in experimental settings, yet many existing algorithms have limited application
outside of a single game or across different experimental settings when parameter values are fixed.
Furthermore, while previous studies have investigated algorithmic agent performance relative to
experimental data, they have relied upon data from a single source. In this study, we use a horse-race
approach to compare the performance of four learning algorithms (Impulse-Matching Learning,
Self-Tuning Experience Weighted Attractions, and Individual Evolutionary Learning(x2)) across five
different sets of experimental data generated by multiple researchers where the subjects face congestion.
We examine the ability of each algorithm to replicate experimental data independent of the training
data set used to determine the initial parameter values via the root mean squared error for each
algorithm relative to the data produced by the human subjects and the ability of the algorithms to
match multiple experimental equilibria despite adjusting the payoffs, the number of players, and the
number of repetitions played. We determined that the Individual Evolutionary Learning model with a
modified set of assumptions has the closest fit of the regularities seen in the experimental data when
human subjects were given full information measured by the average mean squared distance, but not
in experiments with limited information.
“Learning Correlated Equilibria: An Evolutionary Approach,” joint with Jasmina Arifovic and John Duffy
(UC Irvine)
Abstract: Correlated equilibrium (Aumann 1974, 1987) is an important generalization of the Nash
equilibrium concept for multiplayer non-cooperative games. In a correlated equilibrium, players
rationally condition their strategies on realizations of a common external randomization device and,
as a consequence are able to achieve payoffs that Pareto dominate any of the game’s Nash equilibria.
In this paper we explore whether such correlated equilibria can be learned over time using evolutionary
learning model where agents do not start with any knowledge of the distribution of random draws
made by the external randomization device. Furthermore, we validate our learning algorithm findings
by comparing the limiting behavior of simulations of our algorithm with both the correlated
equilibrium of the game and the behavior of human subjects that play that same game. Our results
suggest that our evolutionary learning model is capable of learning the correlated equilibria of these
games in a manner that approximates well the learning behavior of human subjects.
