Bayesian posteriors for arbitrarily rare events by Fudenberg, Drew, He, Kevin, Imhof, Lorens A.

“…We study how much data a Bayesian observer needs to correctly infer the relative likelihoods of two events when both events are arbitrarily rare. Each period,…”

Evolutionary games in deme structured, finite populations by Hauert, Christoph, Imhof, Lorens A.

“…We describe a fairly general model for the evolutionary dynamics in a sub-divided (or deme structured) population with migration and mutation. The number and…”

Evolutionary Cycles of Cooperation and Defection by Imhof, Lorens A., Fudenberg, Drew, Nowak, Martin A., May, Robert M.

“…The main obstacle for the evolution of cooperation is that natural selection favors defection in most settings. In the repeated prisoner's dilemma, two…”

Imitation processes with small mutations by Fudenberg, Drew, Imhof, Lorens A.

“…This note characterizes the impact of adding rare stochastic mutations to an “imitation dynamic,” meaning a process with the properties that absent strategies…”

Fast convergence in evolutionary models: A Lyapunov approach by Ellison, Glenn, Fudenberg, Drew, Imhof, Lorens A.

“…Evolutionary models in which N players are repeatedly matched to play a game have “fast convergence” to a set A if the models both reach A quickly and leave A…”
