Coordination in Transient Social Networks: An Agent-Based Computational Model on the Timing of Retirement

Abstract

A model of retirement decision-making is described in which a relatively small number of agents are rational. Such agents behave as if they compute the optimal age at which to retire. A small proportion of agents retire at random. A majority of the population engages in imitative behavior. An imitative agent retires once a certain fraction of the agents in its social network have retired. The model is analyzed by agent-based computational techniques. It is demonstrated that high levels of optimal behavior can result in the aggregate despite low levels of individual rationality.
