Abstract: This paper explores international portfolio choice in a multi-country, multi-good general equilibrium setting which features time-varying risk aversion generated by external habit formation. It is shown that time variation in conditional risk aversion generates time variation in the countries' relative consumption expenditure. As a result, financing equilibrium consumption entails hedging against adverse fluctuations in risk aversion. In equilibrium, an increase in home risk aversion tends to appreciate the home equity and depreciate the foreign equity, so each agent hedges by shifting her equity portfolio towards the home equity claim. Furthermore, the model is able to generate realistic asset price and exchange rate dynamics, satisfying a long-standing need of the general equilibrium literature in international finance.
