Tiny changes in the American monetary policy can have dramatic effects on the rest of the world because of dollar's double role of national and international currency. This is the Triffin dilemma. The paper shows how it works through three examples: price of commodities, dollarization, and the...

Many commentators have argued that if the Federal Reserve had followed a stricter monetary policy earlier this decade when the housing bubble was forming, and if Congress had not deregulated banking but had imposed tighter financial standards, the housing boom and bust - and the subsequent...

Global risk-off shocks can be highly destabilizing for financial markets and, absent an adequate policy response, may trigger severe recessions. Policy responses were more complex for developed economies with very low interest rates after the Global Financial Crisis (GFC). We document, however,...

Global risk-off shocks can be highly destabilising for financial markets and, absent an adequate policy response, may trigger severe recessions. In Caballero and Kamber (2019), we document that the unconventional policies adopted by the main central banks were effective in containing asset price...

Available evidence supports the view that growth is faster in more open economies. In order to analyze the implications of openness and growth on determinacy and learnability of worldwide rational expectations equilibria we develop a two-country New Keynesian model with growth. We analyze these...

In this paper we investigate the price, volatility and micro-level effects of central bank swap lines during the 2020 pandemic. These policies lowered the ceiling on covered interest rate parity violations and reduced volatility following settlement of swap line auctions. We then combine...

This paper shows that dollar appreciations lead to declines in GDP, investment, and credit to the private sector in emerging market economies (EMEs). These results imply that the transmission of dollar movements to EMEs occurs mainly through financial conditions rather than net exports, contrary...

We explore the role of ‘dollar shortage' shocks and central bank swap lines in a two-country New Keynesian model with financial frictions. Domestic banks issue both domestic and foreign currency debt and lend in domestic currency. Foreign currency-specific funding shocks, which are amplified...
