Until recently, financial services regulation remained largely segmented along national lines. The integration of financial markets, however, calls for a systematic and coherent approach to regulation. This paper studies the effect of market based regulation on the proper functioning of the...

In the presence of uninsurable idiosyncratic risk, the optimal credit contract allows for the possibility of default. In addition, the optimal contract incorporates a precautionary savings motive over and above what agents would otherwise save. When default is sufficiently high, credit markets...

This paper argues that in a homogeneous monetary Real Business Cycle economy where a complete set of nominal contingent claims exist, the requirement to collateralize loans, alone, does not affect the equilibrium allocation when monetary policy is chosen optimally: the Pareto optimal allocation...

We study a monetary economy with two large open economies displaying net real and financial flows. If default on cross-border loans is possible, taxing financial flows can reduce its negative consequences. In doing so it can improve welfare unilaterally, in some cases in a Pareto sense, via...

We present an integrated framework for the study of the international financial economy with trade, fiat money, monetary and fiscal policy, endogenous default and regulation. Money is introduced via a cash-in-advance requirement and real trade is endogenous. The standard international finance...

The post-2008 period focused attention on "twin-crises". Banking crises may lead to sovereign crises where fiscal vulnerabilities are exacerbated by the extension of support for the banking system. We develop a model that describes private sector generated capital inflow that is used to finance...

Most discussions of the Greek debt overhang have focussed on the implications for Greece. We show that when additional funds released to the debtor (Greece), via debt restructuring, are used efficiently in pursuit of a practicable business plan, then both debtor and creditor can benefit. We...

This paper explores how different types of financial regulation could combat many of the phenomena that were observed in the financial crisis of 2007 to 2009. The primary contribution is the introduction of a model that includes both a banking system and a “shadow banking system” that each...
