The process of financial globalization has significantly altered the environment in which national monetary policy authorities operate. What implications does this have for the design of monetary policy? The question can be properly addressed only in the context of a model where monetary policy...

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

Over the one and a half decades prior to the global financial crisis, advanced economies experienced a large growth in gross external portfolio positions. This phenomenon has been described as Financial Globalization. Over roughly the same time frame, most of these countries also saw a...

In the aftermath of the global financial crisis, the state of macroeconomic modeling and the use of macroeconomic models in policy analysis has come under heavy criticism. Macroeconomists in academia and policy institutions have been blamed for relying too much on a particular class of...

We examine optimal policy in a two-country model with uncertainty and learning, where monetary policy actions affect the real economy through the real exchange rate channel. Our results show that whether policy should be cautious or activist depends on the size of one country relative to...

Central banks can go broke and have done so, although mainly in developing countries. The conventional balance sheet of the central bank is uninformative about the financial resources it has at its disposal and about its ability to act as an effective lender of last resort and market marker of...

Open economy macroeconomics typically abstracts from portfolio structure. But the recent experience of financial globalization makes it important to understand the determinants and composition of gross country portfolios. This paper presents a simple approximation method for computing...

The paper considers the pros and cons for Canada of monetary union between Canada and the U.S. The current Canadian monetary arrangements, a flexible exchange rate and an inflation target, are contrasted both with a unilateral adoption by Canada of the U.S. dollar and with a full, formally...

This Paper considers the implications of incomplete exchange rate pass-through for optimal monetary and exchange rate policy. A two-country model is presented which allows an explicit derivation of welfare functions in terms of a weighted sum of the second moments of producer prices and the...

This paper presents a general approximation method for characterizing time-varying equilibrium portfolios in a two-country dynamic general equilibrium model. The method can be easily adapted to most dynamic general equilibrium models, it applies to environments in which markets are complete or...
