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...

This paper shows that the price impact of foreign official (FO) purchases or sales of U.S. Treasuries (USTs) is about twice as large as previously reported in the literature once critical sources of endogeneity are addressed. We also show that prevailing estimates of this price impact suffer...

This study explores the consequences of dollarizing an economy with an initial dollar shortage. We show that the resulting transitional dynamics are tantamount to that of a "sudden stop": consumption of tradable goods fall, the real exchange rate depreciates abruptly by a discrete drop in...

We study the international transmission of U.S. monetary policy (FED hikes) and a strong U.S. dollar. Both of these variables are endogenous and thus we follow the recent developments in the literature to measure the exogenous components of each from the perspective of the rest of the world...

Recent theories of exchange rate determination have emphasized limited UIP arbitrage by international financial institutions. New regulations since 2008 have also lead to imperfect CIP arbitrage. We show that under limited CIP arbitrage the exchange rate and CIP deviation are jointly determined...

The paper explores empirically the tight links between exchange rates and the global network of equity holdings. Exchange rates can be expressed in terms of "equity net currency supplies", i.e. local currency stock market capitalization minus equity holdings, denominated in investors'...

We explore the role of sectoral debt dynamics in shaping business cycles in a sample of 52 Emerging Market Economies (EMEs) and Frontier Market Economies (FMEs) from 2005 to 2021. Higher household debt levels and growth are associated with significantly slower GDP growth in more developed EMEs...
