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...

In this companion paper to Goodhart et al. (2012), we explore the interactions of various types of financial regulation. We find that regulations that control fire-sale risk are critical for delivering financial stability and improving the welfare of savers and borrowers. We describe the...

What is the main limitation of much modern macroeconomic theory, among the failings pointed out by William R. White at the 2010 Mayekawa Lecture? We argue that the main deficiency is a failure to incorporate the possibility of default, including that of banks, into the core of the analysis....

International monetary relationships have been under strain in recent years. This is largely because adjustment mechanisms are asymmetric; the IMF has no means of putting pressure on countries with large current account surpluses to adjust. But such countries' accompanying capital account...

Busts after periods of prolonged prosperity have been found to be catastrophic. Financial institutions increase their leverage and shift their portfolios towards projects that were previously considered too risky. This results from institutions rationally updating their expectations and becoming...

This paper assesses the choice of different regulatory policy instruments for crisis management and prevention. We show that Capital and Liquidity Requirements (as Basel III proposes) are not sufficient to ensure Financial Stability. Three different tools are required to address three different...
