Convergence empirics across economies with (some) capital mobility

This paper uses a model of growth and imperfect capital mobility across multiple economies to characterize the dynamics of (cross-country) in- come distributions. This allows convenient study of the convergence hypothesis, and reveals, where appropriate, polarization and clumping within subgroups. The data show little cross-country convergence; in- stead, the important features are persistence, immobility, and polariza- tion, exemplied by \convergence club" or \twin peaks" dynamics
