The purpose of this paper is to analyze how shocks propagate through a network of firms that borrow from, and lend to, each other in a trade credit chain, and to quantify the effects of financial contagion across firms. I develop a theoretical model of financial contagion, in which the default...

This volume contains a collection of papers, commentaries and speeches that review the strategic and operational decisions taken by the central banks to combat the crisis and that reflect on the lessons for the future. The contributions are grouped around five broad topics: monetary policy...

We study identiÞcation in a class of three-equation monetary models. We argue that these models are typically not identiÞed. For any given exactly identiÞed model, we provide an algorithm that generates a class of equivalent models that have the same reduced form. We use our algorithm to...

We develop a technique for analyzing the response dynamics of economic variables to structural shocks in linear rational expectations models. Our work differs fromstandard SVARs since we allow expectations of future variables to enter structural equations. We show how to estimate the...

We study how determinacy and learnability of global rational expectations equilibrium may be affected by monetary policy in a simple, two country, New Keynesian framework. The two blocks may be viewed as the U.S. and Europe, or as regions within the euro zone. We seek to understand how monetary...
