Three of the most important recent facts in global macroeconomics - the sustained rise in the US current account deficit, the stubborn decline in long run real rates, and the rise in the share of US assets in global portfolio - appear as anomalies from the perspective of conventional wisdom and...

The strong and volatile rebound of capital inflows, mostly portfolio investments, into emerging economies in the recovery process of the 2008 global financial crisis has brought the issue of capital controls to the forefront once again. The presence of global imbalances and unconventional...

During emerging market crises, domestic agents might have sufficient collateral to borrow from the other domestic agents, but they are unable to borrow from foreigners because the country, as a whole, lacks international collateral. In this setting, we show that an (ex-post) optimizing central...

The last few years have seen a significant re-evaluation of the models used to analyze crises in emerging markets. Recent models typically stress financial constraints or distorted financial incentives. While this certainly represents progress, these models share a weakness with the earlier...

This paper analyses the issues raised by EMU for the relationships between the euro area and the international financial system. The depreciation of the euro exchange rate since the beginning of EMU has attracted most attention. The paper argues that none of the conventional explanations is...

This paper explores the effect of global shocks in a two-country New Keynesian model in which US government debt has an advantage as a superior collateral asset in the balance sheets of banks. We show that the model can account for the observed response of the US dollar and US bond returns to a...

The United States (US) extracts a large macroeconomic premium from foreigners: she enjoys higher consumption and GDP growths on average relative to the rest of the world (ROW). This is earned even though the US is relatively insulated against global consumption and GDP risks, challenging a...

What determines the composition of international portfolio investments remains an open question in international finance. In this paper, I propose a theory of international portfolio choice where trade networks play a key role. I solve in closed form for the optimal equity and bond portfolio...

Recent research has shown that gross capital inflows and outflows are positively correlated and highly procyclical. This poses a puzzle since most theory predicts that capital inflows and outflows should be negatively correlated, and while capital inflows should be procyclical, capital outflows...
