Bankruptcy Codes and Risk Sharing of Currency Unions

Abstract

Since the Eurozone Crisis of 2010-12, a critical debate on the viability of a currency union has focused on the role of a fiscal union in adjusting for country heterogeneity. However, a fully-fledged fiscal union may not be politically feasible. This paper develops a two-country general equilibrium model to examine the benefits of the bankruptcy code of a capital markets union - in the absence of a fiscal union - as an alternative mechanism to improve the financial stability and welfare of a currency union. When domestic credit risks are present, I show that a lenient bankruptcy code in the cross-border capital markets union removes the pecuniary externality of banking insolvency, so it leads to a Pareto improvement within the currency union. Moreover, the absence of floating nominal exchange rates removes a mechanism to neutralise domestic credit risks; I show that softening the bankruptcy code can recoup the lost benefits of floating nominal exchange rates. The model provides the financial stability and welfare implications of bankruptcy within a capital markets union in the Eurozone.
