We provide an overview of the recent developments of the literature on the determinants of long-term capital flows, global imbalances, and valuation effects. We present the main stylized facts of the new international financial landscape in which external balance sheets of countries have grown...

We survey the recent empirical and theoretical developments in the literature on the relation between prices and exchange rates. After updating some of the major findings in the empirical literature, we present a simple framework to interpret this evidence. We review theoretical models that...

In recent years the US current account deficit has grown to the point that most observers consider its level to be already unsustainable. Yet it seems set to continue to increase in the foreseeable future, with net foreign debt likely to surge. This paper describes the present deficit from three...

We study the role of exchange rates in industrial policy. We construct an open-economy macroeconomic framework with production externalities and show that the desirability of these policies critically depends on the dynamic patterns of externalities. When they are stronger in earlier stages of...

This paper analyzes the drivers of international waves in capital flows. We build on the literature on “sudden stops” and “bonanzas” to develop a new methodology for identifying episodes of extreme capital flow movements using quarterly data on gross inflows and gross outflows,...

The economics profession seems to increasingly endorse the existence of a strongly negative nonlinear effect of public debt on economic growth. Reinhart and Rogoff (2010) were the first to point out that a public debt-to-GDP ratio higher than 90% of GDP is associated with considerably lower...

G-Cubed is a multi-country, multi-sector, intertemporal general equilibrium model that has been used to study a variety of policies in the areas of environmental regulation, tax reform, monetary and fiscal policy, and international trade. It is designed to bridge the gaps between three areas of...

This paper studies the welfare implications of sectoral labor adjustment cost in a two-sector small open economy model with sticky prices. We find that, when the economy faces external shocks, if monetary policy can stabilize the real economy, then sectoral labor market adjustment cost will lead...

Global value chains (GVCs) have grown rapidly over the past several decades. Over the same period, the aggregate value of current account imbalances has risen substantially. This paper looks at whether these developments are related. While there is a sizable literature that has documented the...
