Coordination in a Mobile World

Abstract

We study coordination failures in many simultaneously occurring coordination problems called projects. Players encounter one of these projects, but have an outside option to search for another of the projects. Drawing on the global games approach, we show that such a mobile game has a unique equilibrium which allows us to examine comparative statics. The endogeneity of the outside option value and of the search activity leads to non-monotonicity of welfare with respect to search costs; high mobility may hurt players. Moreover, outcomes of the mobile game are remarkably robust to changes in the exogenous parameters. In contrast to the “static” benchmark global game without a search option, successful coordination is frequent in the mobile game even for extremely poor distributions of economic fundamentals, and coordination failures are common even for extremely good distributions. The strategic consequences of the search option are robust to various modifications of the model.
