When available financial securities allow investors to optimally diversify risk across countries, standard theory implies that exchange rates should reflect this behavior. However, exchange rates observed in the data deviate from these predictions. In this paper, we develop a framework to value...

We develop a general policy analysis framework for an open economy that features nominal rigidities and financial frictions giving rise to endogenous PPP and UIP deviations. The efficient allocation can be implemented with monetary policy closing the output gap and FX interventions eliminating...

We investigate the event-based geopolitical shocks from the Russian invasion of Ukraine on selected agricultural and energy commodities using daily event-based structural vector autoregression (SVAR). We find that the geopolitical shock affects the markets of wheat (3%) and European natural gas...

This paper uses the recent cross-country experience with quantitative tightening (QT) to assess the impact of shrinking central bank balance sheets. We analyze the experience in seven advanced economies (Australia, Canada, Euro area, New Zealand, Sweden, UK and US)--documenting different...

We characterize how risk evolves during a crisis. Using high-frequency data, we find that the first two principal components (PCs) of the covariance matrix of global asset returns experience large, sudden, and temporary spikes coinciding with well-known crises - Covid-19 pandemic, Global...

China's admission into the WTO in 2001 heralded a new era of globalization, increasing both import competition in domestic markets and foreign opportunities for US firms. In the aggregate, the average annual profitability of US public firms during the post globalization period (2003-2019)...

Monetary rules may have a large effect on the outcome of trade wars if central banks target the CPI inflation rate or more generally changes in the relative price of traded goods. We lay out a two-country open-economy model with sticky prices where countries engage in trade wars. In the presence...

Empirical work finds that flows of investments from the U.S. and other high income countries to emerging markets increase during times of quantitative easing by the U.S. Federal Reserve, and the reverse movement occurs under quantitative tightening. We offer new evidence to confirm these...

We study sovereign external debt crises over the past 200 years, with a focus on creditor losses, or "haircuts". Our sample covers 327 sovereign debt restructurings with external private creditors over 205 default spells since 1815. Creditor losses vary widely (from none to 100%), but the...

We construct a two-country New Keynesian model in which US government debt has an advantage as a superior collateral asset in the balance sheets of banks. The model can account for the observed response of the US dollar and US bond returns to a global downturn, in particular when the downturn is...
