Standard models of international risk sharing with complete asset markets predict a positive association between relative consumption growth and real exchange-rate depreciations across countries. The striking lack of evidence for this link - the consumption/real-exchange-rate anomaly or...

This study analyzes a two-country dynamic general equilibrium model with nominal rigidities,monopolistic competition and producer currency pricing. A quadratic approximation to the utility ofthe consumers is derived and assumed as the policy objective function of the policymakers.It is shown...

In this paper, the following question is posed: Can the New KeynesianOpen Economy Model by Galí and Monacelli (2005b) explain “Six MajorPuzzles in International Macroeconomics”, as documented in Obstfeldand Rogoff (2000b)?The model features a small open economy with complete markets,...

Recent research has demonstrated that while government expenditures are countercyclical inmost industrialized countries, they tend to be procyclical in developing countries. We develop adynamic political economy model to explain this phenomenon. In the model, public expendituresprovide insurance...

This paper analyzes a useful accounting framework that breaks down the current account to twocomponents: a composition effect and a growth effect.We show that past empirical evidence, which stronglysupports the growth effect as the main driver of current account dynamics, is misconceived. The...

This paper provides a new theory of international capital ows. In a frameworkthat integrates factor-proportions-based trade and nancial capital ows, a novel forceemerges: capital tends to ow towards countries that become more specialized incapital-intensive industries. This `composition' eect...

The `quantity anomalies' that arise from standard international business cycle models are cross-country correlations in consumption being higher than output, and negative comovement in aggregate investment and employment. This paper shows thatincorporating multiple sectors with heterogeneous...

This paper studies the optimal design of monetary policy in an optimizing two-country sticky price model. We suppose that the production sequence of final consumption goods stretches across both contries and is associated with vertical trade. Prices of final consumption goods are sticky in the...

We study the effects of model uncertainty in a simple New Keynesian model using robustcontrol techniques. Due to the simple model structure, we are able to find closed-formsolutions for the robust control problem, analyzing both instrument rules and targetingrules under different timing...

This paper highlights relative price adjustments taking place in the global economy as important sources of the lower levels of inflation rates observed in the recent decades. Using a markup model, it shows substantial effects from declines in wage costs and import prices relative to consumer...
