The paper highlights the increased dispersion in net external positions in recent years, particularly among industrial countries. It provides a simple accounting framework that disentangles the factors driving the accumulation of external assets and liabilities (such as trade imbalances,...

The period preceding the global financial crisis was characterized by a substantial widening of current account imbalances across the world. Since the onset of the crisis, these imbalances have contracted to a significant extent. In this paper, we analyze the ongoing process of external...

The effects of income and consumption taxation are examined in the context of models in which the growth process is driven by the accumulation of human and physical capital. The different channels through which these taxes affect economic growth are discussed, and it is shown that in general the...

This paper examines the effects of taxation of human capital, physical capital and foreign assets in a multi-sector model of endogenous growth. It is shown that in general the growth rate is reduced by taxes on capital and labor (human capital) income. When the government faces no borrowing...

This paper studies the effects of human and physical capital income taxation on growth, and examines how these effects depend on the technologies for human capital accumulation and 'leisure'. It then derives the normative implications of the analysis for the optimal taxation of factor incomes....

We examine the evolution of international currency exposures, with a particular focus on the 2002-12 period. During the run up to the global financial crisis, there was a widespread shift towards positive net foreign currency positions, such that relatively few countries exhibited the archetypal...

A major focus of the recent literature on the determination of optimal portfolios in open-economy macroeconomic models has been on the role of currency movements in determining portfolio returns that may hedge various macroeconomic shocks. However, there is little empirical evidence on the...

Our goal in this project is to gain a better empirical understanding of the international financial implications of currency movements. To this end, we construct a database of international currency exposures for a large panel of countries over 1990-2004. We show that trade-weighted exchange...

International financial integration allows countries to become net creditors or net debtors with respect to the rest of the world. In this paper, we show that a small set of fundamentals--shifts in relative output levels, the stock of public debt and demographic factors--can do much to explain...

We document a striking empirical regularity: Latin American savings rates are as a rule substantially less procyclical than for OECD countries and in some cases are actually countercyclical. We build a non-representative agent intertemporal macroeconomic model that rationalizes this phenomenon...
