Financial integration generates macroeconomic spillovers that may require international monetary policy coordination. We show that individual central banks may set nominal interest rates too low or too high relative to the cooperative outcome. We identify three sufficient statistics that...

This paper examines the role of foreign exchange (FX) reserves and other fundamental factors in explaining cross-country differences in foreign currency depreciation observed over the 2021-22 Federal Reserve monetary policy tightening cycle that led to a sharp appreciation of the US dollar....

Are unregulated capital flows excessive during a stagflation episode? We argue that they likely are, owing to a macroeconomic externality operating through the economy's supply side. Inflows raise domestic wages through a wealth effect on labor supply and cause unwelcome upward pressure on...

In this paper we revisit the Canadian experience with floating exchange rates since 1950. Canada was a pioneer in successfully adopting a floating exchange rate during the Bretton Woods pegged exchange rate regime. Since then, most advanced countries have followed the Canadian example

We investigate the determinants of emerging markets performance during five U.S. Federal Reserve monetary tightening and easing cycles during 2004-2023. We study how macroeconomic and institutional conditions of an Emerging Market (EM) at the beginning of a cycle explain EM resilience during...

This paper studies how household inequality shapes the effects of the zero lower bound (ZLB) on nominal interest rates on aggregate dynamics. To do so, we consider a heterogeneous agent New Keynesian (HANK) model with an occasionally binding ZLB and solve for its fully non-linear stochastic...

The Covid pandemic disrupted supply chains and labor markets, with heterogeneous effects on demand and supply across industries. Meanwhile governments responded with unprecedented stimulus packages, and inflation increased to its highest values in 40 years. In this paper I investigate the...

We study a new type of monetary-fiscal interaction in a heterogeneous-agent New Keynesian model with a fiscal block. Due to household heterogeneity, the stock of public debt affects the natural interest rate, forcing the central bank to adapt its monetary policy rule to the fiscal stance to...
