During emerging market crises, domestic agents might have sufficient collateral to borrow from the other domestic agents, but they are unable to borrow from foreigners because the country, as a whole, lacks international collateral. In this setting, we show that an (ex-post) optimizing central...

This paper highlights some of the theoretical and practical implications for monetary policy and exchange rates that derive specifically from the presence of a global general equilibrium factor embedded in neutral real policy rates in open economies. Using a standard two country DSGE model, we...

I argue that countries' dollar-denominated net external debt (dollar debt) helps explain the large differences in risk premia across currencies and how U.S. monetary policy affects the global economy. When the U.S. dollar strengthens, the real value of dollar debt increases, weakening the...

A key challenge facing most emerging market economies today is how to simultaneously maintain monetary independence, exchange rate stability and financial integration subject to the constraints imposed by the Trilemma, in an era of widespread globalization. In this paper we overview and contrast...

We present evidence of significant bias in event studies that investigate the effect of U.S. monetary policy on U.S. stock prices. To overcome this bias, we propose a new identification method based on the "Impossible Trinity" theory which argues that an economy with a fixed exchange rate and...

A key challenge facing most emerging market economies today is how to simultaneously maintain monetary independence, exchange rate stability and financial integration subject to the constraints imposed by the Trilemma, in an era of widespread globalization.

Understanding the changing role of central banks and the novel policies they have pursued recently is absolutely essential for analysing many economic, financial and political issues, ranging from financial regulation and crisis, to exchange rate dynamics and regime changes, and QE and prolonged...

The study investigated the effect of external economic shocks on monetary policy tools in Nigeria for a period of 1990 to 2020. External economic shocks were measured though their passthrough variables of exchange rate (EXR), foreign direct investment (FDI), external debt (ED), and trade...

In this paper, I develop a two-country general equilibrium model with financial frictions to study the global consequences of quantitative easing (QE) and foreign exchange reserve accumulation. In the model, the key financial frictions are limited commitment and differential pledgeability of...

A key challenge facing most emerging market economies today is how to simultaneously maintain monetary independence, exchange rate stability and financial integration subject to the constraints imposed by the Trilemma, in the era of deepening globalization. In this paper we study the Trilemma...
