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 particular, theauthorsdescribeconditionsunderwhichtwodifferentequilibriaexist. One has a high level of outputand a minorcostly-state-veri?cationproblem, and the other equilibrium has a higher level of output and a severe costly-state-veri?cation problem. 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. This analysis is carried out within a context where ?nancial intermediaries perform a real allocative function, there are multiple reserverequirements, andtheeconomyissubjecttocreditmarketfrictions. She?nds there is scope for endogenousvolatility, independent of the exchange rate regime in place. 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.
