Foreign exchange intervention redux
Arguably no issue in International Macroeconomics exhibits more dissonance between academic research and policy practice than foreign-exchange intervention. The dominant view from academia is that sterilized foreign-exchange (FX) intervention has a tiny if any impact on real variables which makes it ...
Implications of rapidly growing emerging markets for the world economy
It is an honor and a pleasure participating in this conference in honor of Vittorio Corbo. He has been a major contributor to the thinking on economic theory and policy with respect to development as an academic as a World Bank official as a consultant and as Governor of the Banco Central de Chile.

Modeling a housing and mortgage crisis
The current crisis has centered on borrower defaults on mortgages and the associated effects on banks’ own credit standing (and in several cases their own default), which in turn led to tightened conditions for lending to new (mortgage) borrowers. Any model that does not incorporate all or most of ...
Commodity connectedness
Commodities and commodity markets play a central role in the global economy. Hence commodity market developments are widely chronicled and followed. Commodities are a key input to all countries’ production and a key output of many emerging economies so fluctuations in commodity prices may contribute ...

While academic economists in developed countries tend to focus more narrowly on research and teaching the diversity ...
Bernanke's no-arbitrage argument revisited: can open market operations in real assets eliminate the liquidity trap?
This paper looks back on the professional consensus about monetary policy at the zero bound prior to the 2008 crisis and proposes a calibrated model that provides one interpretation to explain why it was somewhat off base. The general consensus in the economics profession in the late 1990s when Japan ...
Leverage restrictions in a business cycle model: a comment
The paper by Christiano and Ikeda in this volume is one of the first efforts to quantify the welfare gains of leverage constraints in a macroeconomic model with a banking sector. Unlike other models their answer is that they can be even more desirable when banks hold little equity and intermediation ...
Monetary policy thorugh asset markets: lessons from unconventional measures and implications for an integrated world
The global financial crisis of 2008 and its aftermath have brought many new challenges for the world’s central banks. These new challenges have in turn resulted in bold experimentation—not simply particularly vigorous use of traditional policy tools but also the use of new tools or if not entirely new ...
