Borrowing from thy neighbour: a European perspective on sovereign debt

Abstract

European capital markets show increasing concern about the extent of sovereign debts and their sustainability. Here we explore some insights that the Overlapping Generations (OLG) framework has to offer on such issues. The OLG framework implies, for example, that there is a limit to the amount of debt that may be sustained in a closed economy- with high debt raising interest rates and crowding out capital formation. But capital market integration with less indebted partners allows for a fall in interest rates as a result of borrowing from one's neighbour. Indeed we find that - in equilibrium - most of the debt of a high indebted country will be transferred to partner countries.debt sustainability, overlapping generations, sovereign default, Euro-zone debt crisis
