Financial globalization was off to a rocky start in emerging economies hit by Sudden Stops since the mid 1990s. Foreign reserves grew very rapidly during this period, and hence it is often argued that we live in the era of a New Merchantilism in which large stocks of reserves are a war-chest for defense against Sudden Stops. We conduct a quantitative assessment of this argument using a stochastic intertemporal equilibrium framework with incomplete asset markets in which precautionary saving affects foreign assets via three mechanisms: business cycle volatility, financial globalization, and Sudden Stop risk. In this framework, Sudden Stops are an equilibrium outcome produced by an endogenous credit constraint that triggers Irving Fisher's debt-deflation mechanism. Our results show that financial globalization and Sudden Stop risk are plausible explanations of the observed surge in reserves but business cycle volatility is not. In fact, business cycle volatility has declined in the post-globalization period. These results hold whether we use the formulation of intertemporal preferences of the Bewley-Aiyagari-Hugget class of precautionary savings models or the Uzawa-Epstein setup with endogenous time preference.

This paper examines the effects that windfalls from international commodity price booms have on net foreign assets in a panel of 145 countries during the period 1970-2007. The main finding is that windfalls from international commodity price booms lead to a significant increase in net foreign assets, but only in countries that are ethnically homogeneous. In highly ethnically polarized countries, net foreign assets significantly decreased. To explain this asymmetry, the paper shows that in ethnically polarized countries commodity windfalls lead to large increases in government consumption expenditures and political corruption. The paper's findings are consistent with theoretical models of the current account that have a built-in voracity effect.
