On the eve of a major change in the world monetary system, the adoption of a single currency in Europe, our theoretical understanding of the implications of the exchange rate regime for trade and capital flows is still limited. We argue that two key model ingredients are essential to address...

We develop a theory to account for changes in net capital flows of safe and risky assets over the global financial cycle. We show empirically that countries that have a net debt of safe assets experience a rise in net outflows of safe assets (reduced accumulation of safe debt) during a downturn...

We develop a theory to account for changes in gross and net capital flows over the global financial cycle (GFC). The theory relies critically on portfolio heterogeneity among investors within and across countries, related to risky portfolio shares and portfolio shares allocated to foreign...

Recent crises have seen very large spikes in asset price risk without dramatic shifts in fundamentals. We propose an explanation for these risk panics based on self-fulfilling shifts in risk made possible by a negative link between the current asset price and risk about the future asset price....

The past decade has witnessed an explosion of papers estimating gravity equations for cross-border financial holdings. The aim of the paper is to develop a theoretical foundation for the empirical gravity literature applied to finance. The gravity specification is closely analogous to that...

Obstfeld and Rogoff (2000) have reinvigorated an old literature on the link between home bias in the goods market and home bias in the asset market by arguing that trade costs in the goods market can account for the observed portfolio home bias. The key link between home bias in the two markets...

The gravity model has been widely used to infer substantial trade flow effects of institutions such as customs unions and exchange rate mechanisms. McCallum [1995] found that the US-Canada border led to trade between provinces that is a factor 22 (2,200%) times trade between states and...

While empirical evidence finds only a weak relationship between nominal exchange rates and macroeconomic fundamentals, forex markets participants often attribute exchange rate movements to a macroeconomic variable. The variables that matter, however, appear to change over time and some variable...

Nominal rigidities due to menu costs have become a standard element in closed economy macroeconomic modeling. The 'New Open Economy Macroeconomics' literature has investigated the implications of nominal rigidities in an open economy context and found that the currency in which prices are set...

The sharp increase in both gross and net capital flows over the past two decades has led to a renewed interest in their determinants. Most existing theories of international capital flows are in the context of models with only one asset, which only have implications for net capital flows, not...
