In a two-country portfolio model with leverage constraints, I focus on private assets in order to understand how their behaviour can justify an expected excess return as well as the flight-to-safety observed in the data. The specific goal is to study how much these phenomena are explained by the...

We document the exchange rate hedging channel that connects country-level measures of net external financial imbalances with exchange rates. In times of market distress, countries with large positive external imbalances (e.g. Japan) experience domestic currency appreciation, and crucially,...

This paper studies the role of the financial sector in affecting domestic resource allocation and cross-border capital flows. I develop a quantitative, two-country, macroeconomic model in which banks face endogenous and occasionally binding leverage constraints. Banks lend funds to be invested...

Over the past decade, European investment funds have substantially increased their investment in dollar-denominated assets to more than 3.8 USD trillion, which should give raise to substantial currency hedging if US investor have reciprical currency exposures in their international portfolios....

This paper investigates mean reversion properties of real effective exchange rates (REERs) using a semi-parametric quantile autoregression approach. This method accounts for non-normality and captures asymmetric and dynamic adjustments towards the REER's long run equilibrium, conditional on the...

This paper studies the role of the financial sector in a↵ecting domestic resource allocation and cross-border capital flows. I develop a quantitative, two-country, macroeconomic model in which banks face endogenous and occasionally binding leverage constraints. Banks lend funds to be invested...

We propose a model of endogenous, persistent coordination on the international medium of exchange. An asset becomes the dominant international medium because it is widely held, and remains widely held because it is dominant. The country issuing the dominant asset is a net debtor, but earns an...

Using a stylized two-period model we compare portfolio solutions from two local solution approaches - the approach of Judd and Guu (2001) and the approach of Devereux and Sutherland (2010, 2011) - with the true nonlinear portfolio solution.
