The paper provides a unified analysis of globalization effects on the inflation-output tradeoff and monetary policy, in the New-Keynesian framework. The main proposition of the paper is threefold. First, labor, goods, and capital mobility tend to flatten the tradeoff between inflation and...

This article analyzes the work of the late Dr. William Vickrey, the McVickar Professor Emeritus of Columbia University and 1996 Nobel-laureate in Economics. In choosing Vickrey for the Nobel prize, the Royal Swedish Academy of Sciences notes Vickrey's fundamental contributions to the economic...

We analyze a recent paper that claims that dollarizing an economy in the presence of a “dollar shortage” will provoke an immediate sharp reduction in real output and welfare. We find many problems with the model that supports this conclusion: confusion about the nature of a dollar shortage...

We compare and contrast two prominent notions of financial cycles: a domestic variant, which focuses on how financial conditions within individual economies lead to boom-bust cycles there; and a global variant, which highlights how global financial conditions affect individual economies. The two...

We examine the open-economy implications of the introduction of a central bank digital currency (CBDC). We add a CBDC to the menu of monetary assets available in a standard two-country DSGE model with financial frictions and consider a broad set of alternative technical features in CBDC design....

We provide a theory of the limits to monetary policy independence in open economies arising from the interaction between capital flows and domestic collateral constraints. The key feature of our theory is the existence of an 'Expansionary Lower Bound' (ELB), defined as an interest rate threshold...

Inflation volatility is clearly important for structural analysis, forecasting and policy purposes, yet it is often overlooked in the literature. This paper compares in ation volatility among advanced open economies with in ation targeting monetary policy frameworks. The results of the empirical...

Historically, the world payments system has been dominated by a single currency accepted in the exchange of goods and assets among countries. In recent decades, the US dollar has played this role. The dollar acts as a 'vehicle currency' in the sense that agents in non-dollar economies will...

We build a model of the global financial cycle with one key ingredient: the demand for safe dollar assets. The model matches patterns of dollar borrowing and currency mismatch, the U.S. external balance sheet, low U.S. interest rates and exorbitant privilege, spillovers of the U.S. monetary...

This paper examines the interaction between monetary policy and macroprudential policy and whether policy makers should respond to financial imbalances. To address this issue, we build a dynamic general equilibrium model that features financial market frictions and financial shocks as well as...
