Abstract:
This paper extends the general equilibrium model with incomplete markets to an open-ended future, thereby providing a natural setting for analyzing problems in macroeconomics. Two concepts of equilibrium are defined that prevent agents from entering into Ponzi schemes: the first is based on debt constraints and the second is based on a transversality condition that limits the rate of growth of debt. Under the assumption that agents are impatient (Mackey continuity of preferences) and have a degree of impatience that is bounded below, the two concepts of equilibrium are shown to coincide and lead to existence of equilibrium.
