This paper analyzes a useful accounting framework that breaks down the current account to two components: a composition effect and a growth effect. We show that past empirical evidence, which strongly supports the growth-eect as the main driver of current account dynamics, is mis- conceived. The...

We show that in an open-economy OLG model, the interaction between growth differentials and household credit constraints, more severe in fast-growing countries, can explain three prominent global trends: a divergence in private saving rates between advanced and emerging economies, large net...

The `quantity anomalies' that arise from standard international business cycle models are cross-country correlations in consumption being higher than output, and negative comovement in aggregate investment and employment. This paper shows that incorporating multiple sectors with heterogeneous...

Commodity trade and financial asset trade are both integral parts of globalization, yet little has been studied on their interplay. In a framework that integrates these two paradigms of trade, a new force driving international capital flows emerges: capital tends to flow towards countries that...

Positive investment comovements across OECD economies as observed in the data are difficult to replicate in open-economy real business cycle models, but also vary substantially in degree for individual country-pairs. This paper shows that a two-country stochastic growth model that distinguishes...
