A growing number of papers have studied positive and normative implications of financial frictions in DSGE models. We contribute to this literature by studying the welfare-based monetary policy in a two-country model characterized by financial frictions, alongside a number of key features, like...

How should monetary policy respond to excessive capital inflows that appreciate the currency and widen the external deficit? Using the workhorse two-country open-macro model, we derive a quadratic approximation of the utility-based global loss function in incomplete market economies, and solve...

This paper studies the optimal choice of exchange rate regimes between two large currency areas. It provides a positive and normative analysis of alternative monetary policy rules in a model with sticky prices, monopolistic competition, and frictions in the processes of capital accumulation and...

Major currency areas are characterized by important differences in financial structure that are clear in microeconomic data. Surprisingly, this fact is seldom discussed in the analysis of the international transmission of shocks. This paper attempts to fill the gap. First, I show some stylized...

A central puzzle in international finance is that real exchange rates are volatile and, in stark contradiction to effcient risk-sharing, negatively correlated with cross-country consumption ratios. This paper shows that incomplete asset markets and a low price elasticity of tradables can account...

This paper studies export adjustment to negative shocks in currency unions. I consider the hitherto ignored role of trade costs and taxes in internal devaluations, which have been brought to the fore of international policy during the recent euro periphery crisis. Trade costs can limit the...

This paper surveys the optimum currency area (OCA) literature. It is organised into four phases: the 'pioneering phase' which put forward the OCA theory and its properties, the 'reconciliation phase' when its diverse facets were combined, the 'reassessment phase' that led to the 'new OCA theory'...
