We focus our attention on Chamley's (1993) model of endogenous growth to provide another example of global indeterminacy in continuous-time growth models with infinitely-lived representative agents and some form of market imperfections. By applying the homoclinic bifurcation theorem due to Kopell and Howard (1975), we are able to show that, for special parameter values, the equilibrium dynamics has a bounded region (either surrounded by a family of homoclinic or periodic orbits) in the interior of which there exists an infinite number of solutions (global indeterminacy). In order to characterize global equilibrium dynamics, we have used a particular functional form for the learning function that maintains its original concavity properties.
