nomic activity. The paper highlights how the interaction of domestic informational frictions, perfect capital mobility, and foreign interest rates can combine to provoke a sudden depreciation of the exchange rate and a prolonged decline in output.

In addition, the authors show how their model can successfully simulate a crisispaththatisqualitativelyconsistentwithoccurrencessuchastheMexican?n- cial crisis in 1994. An importantlesson emergingfromthis work is that even a small change in external factors can generate a crisis path, when this initial shock hits a small open monetary economy, if the economy features a combination of domestic informational frictions with international capital ?ows. The next paper, by Hernandez-Verme, also focuses on the study of small open economieswithinthe contextofan overlappinggenerationsmodel. Unlike Antinol? and Huybens, however, her main concern is the relative merits of different methods for achievingprice stability. To do so she mergesthe overlappinggenerationsmodel with a spatial model of Townsendto comparethe meritsof alternativeexchangerate regimes namely, ?xed and ?exible.

Another key ?nding is that under ?oating exchange rates, a positive trade-off between domestic in?ation and output can be exploited under credit rationing but only if in?ation is small. In fact, there exists an in?ation threshold beyond which domestic output suffers.

This book assembles current theoretical contributions to monetary theory, banking and finance. The papers published in this collection span a wide variety of themes, from monetary policy to the optimal design of financial systems, from the study of the causes of financial crises to payment systems design. Thereby, the book serves as a useful reference to all researchers interested in the study of financial systems and monetary economics. The papers contribute to two strands of literature: A first group of papers focuses on topics related to the optimality of financial mechanisms, banking regulation, financial crises, financial fragility, and payment systems. A second group of papers is broadly concerned with the efficiency of the decentralized monetary solution in economies characterized by equilibrium heterogeneity.
