Resumen de The international diversification puzzle is not as bad as you think.
Jonathan Heathcote, Fabrizio Ferri
The international diversification puzzle is the fact that country portfolios are on average biased toward domestic assets, while one-good international macro models with nondiversifiable labor income risk predict the opposite pattern of diversification. This paper embeds a portfolio choice decision in a two-good international business cycle model and provides a closed-form solution for equilibrium country portfolios. Equilibrium portfolios are biased toward domestic assets because endogenous international relative price fluctuations make domestic assets a good hedge against labor income risk. Evidence from developed economies in recent years is qualitatively and quantitatively consistent with the mechanisms highlighted by the theory. [ABSTRACT FROM AUTHOR]
