A key precursor of twentieth-century financial crises in emerging and advanced economies alike was the rapid buildup of leverage. Those emerging economies that avoided leverage booms during the 2000s also were most likely to avoid the worst effects of the twenty-first century’s first global...

This paper presents a model of international portfolios with real exchange rate and non financial risks that accounts for observed levels of equity home bias. A key feature is that investors can trade equities as well as domestic and foreign real bonds. Bonds matter: in equilibrium, investors...

This paper studies the geography of wealth transfers during the 2008 global financial crisis. We construct valuation changes on bilateral external positions in equity, direct investment and portfolio debt at the height of the crisis to map who benefited and who lost on their external exposure....

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 in...

To what extent do national borders and national currencies impose costs that segment markets across countries? To answer this question we use a dataset with product level retail prices and wholesale costs for a large grocery chain with stores in the U.S. and Canada. We develop a model of pricing...

Does the centre country of the International Monetary System enjoy an 'exorbitant privilege' that significantly weakens its external constraint as has been asserted in some European quarters? Using a newly constructed dataset, we perform a detailed analysis of the historical evolution of US...

According to the consensus view in growth and development economics, cross country differences in per-capita income largely reflect differences in countries' total factor productivity. We argue that this view has powerful implications for patterns of capital flows: everything else equal,...

Standard theoretical arguments tell us that countries with relatively little capital benefit from financial integration as foreign capital flows in and speeds up the process of convergence. We show in a calibrated neoclassical model that conventionally measured welfare gains from this type of...

In this paper we argue that the persistent global imbalances, the subprime crisis, and the volatile oil and asset prices that followed it, are tightly interconnected. They all stem from a global environment where sound and liquid financial assets are in scarce supply. Our story goes as follows:...

Recent theories on the origins of crises put lending booms at the root of financial collapses. Yet lending booms may be a natural consequence of economic development and fluctuations. So, are lending booms dangerous? In this Paper, we investigate this question empirically using a broad sample of...
