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...

In this paper, I study the international transmission of shocks when assets traded across borders are differently suitable as collateral for borrowing (i.e., pledgeability). Under financial integration, differences in pledgeability have implications for the demand for assets. For instance, if a...

This paper studies the international transmission of pledgeability shocks, as the recent crisis involved a negative shock to the pledgeability of assets. The paper develops a two-country portfolio model, with leveraged investors, that incorporates this type of shock and a solution approach for...

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,...

I develop an open economy portfolio model to study how leveraged investors' wholesale funding affects the international transmission of shocks. Under binding borrowing limits, there is a link between the international investment positions of integrated economies as investors diversify the asset...

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 last decade foreign bond portfolio positions in US dollar assets have risen above the reciprocal US investor positions in foreign currencies. In periods of increased economic uncertainty, institutional investors hedge their international bond positions, which creates a net hedging...
