Portfolio choice analysis in a multi-country macro model

This paper examines portfolio choice in a dynamic stochastic general equilibrium model with trade and financial linkages across 43 countries. I conduct comparative statics analysis with this structural model to disentangle potential mechanisms of global financial allocation, including risk hedging, risk diversification, risk sharing, and financial friction. For asset home bias, the model predicts that risk hedging is less essential in a multi-country than in a two-country setting. For bilateral asset positions, the model implies that variations in financial friction and asset covariance are major determinants of observed cross-country portfolios. Meanwhile, bilateral financial linkages strongly covary with trade linkages across countries. Comparative statics suggests that this covariance is mainly driven by the high correlation of frictions across the two channels of globalization.(This abstract was borrowed from another version of this item.)
