We develop a simple and intuitive approach for analytically deriving unconditionally optimal (UO) policies, a topic of enduring interest in optimal monetary policy analysis. The approach can be employed to both general linear-quadratic problems and to the underlying non-linear environments. We...

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...

I provide evidence that portfolio equity inflows can have expansionary effects on GDP and inflation if not offset by monetary policy. I use a shift-share instrument to estimate equity inflows based on plausibly exogenous timing of inflows into mutual funds with heterogeneous country portfolios....

A two sector small open economy model developed by Corden (1991, 2002) is used to analyse the impact of sudden stops in capital inflows on an internal and external equilibrium and to explore the merits of disposing of the nominal exchange rate as policy tool in rectifying real exchange rate...

​This paper studies episodes of exceptionally large capital inflows. We find that these events are typically accompanied by an economic boom, and followed by a slump. Moreover, during episodes of large capital inflows capital and labor shift out of the manufacturing sector, especially if the...

This paper examines the role of disaster shock in a one-sector, representative agent dynamic stochastic general equilibrium model (DSGE). First, it estimates a panel vector autoregresive (VAR) model for output, investment, trade balance, consumption, and country spread to capture the economic...

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...

Understanding and predicting the evolution of exports after a change in the nominal exchange rate is of central importance in international economics. Most of the literature focuses on estimating this relationship by reduced form, with the aim of uncovering a single structural parameter, but...

Credit constraints that link a private agent's debt to market-determined prices create a systemic credit externality that drives a wedge between competitive and (constrained) socially optimal equilibria, which induces private agents to "overborrow". We quantify the effects of this externality in...

This paper introduces Heckscher-Ohlin trade features into a two-country DSGE model, and studies how productivity shocks propagate through trade in goods. In comparison with standard models, (i) transitory shocks to productivity have permanent effects on country-level aggregate variables; (ii)...
