How does news about future economic fundamentals affect within-country and cross-country credit allocation? How effective is unconventional policy when financial crises are driven by unfulfilled favorable news? I study these questions by employing a two-sector, two-country macroeconomic model...

Observed international investment positions and cross-country heterogeneity in rates of return to capital are hard to reconcile with frictionless capital markets. In this paper, we develop a theory of international capital allocation: a multi-country dynamic spatial general equilibrium model in...

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.
