Recently portfolio choice has become an important element of many DSGE open economy models. Yet, a substantial body of evidence is inconsistent with standard frictionless portfolio choice models. In this paper we introduce a quadratic cost of changes in portfolio allocation into a two-country...

We introduce a portfolio friction in a two-country DSGE model where investors face a constant probability to make new portfolio decisions. The friction leads to a more gradual portfolio adjustment to shocks and a weaker portfolio response to changes in expected excess returns. We apply the model...

We develop a theory to account for changes in prices of risky and safe assets and gross and net capital flows over the global financial cycle (GFC). The multi-country model features global risk-aversion shocks and heterogeneity of investors both within and across countries. Within-country...
