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 provide a theory of the determination of exchange rates based on capital flows in imperfect financial markets. Capital flows drive exchange rates by altering the balance sheets of financiers that bear the risks resulting from international imbalances in the demand for financial assets. Such...

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 takes a systematic look at the portfolio choice problem faced by investment banks or funds investing in transition economies. We relate the performance of projects in the transition economies to the broader macroeconomic and international environment, which affect the project through...

Home bias is a perennial feature of international capital markets. We review various explanations of this puzzling phenomenon highlighting recent developments in macroeconomic modelling that incorporate international portfolio choices in standard two-country general equilibrium models. We refer...

I provide a framework for understanding debt deleveraging in a group of financially integrated countries. During an episode of international deleveraging world consumption demand is depressed and the world interest rate is low, reflecting a high propensity to save. If exchange rates are allowed...
