The enormous global demand for smartphones in recent years has created a new global tech cycle. In 2016 alone, global smartphone sales reached close to 1.5 billion, one for every fifth person on earth. In turn, this has engendered complex and evolving supply chains across Asia. We show that the...

Superficial examination of aggregate gross cross-border capital inflow data suggests that therewas no substitution between portfolio inflows and bank loans in recent years. However, ournovel analysis of disaggregate inflows (both by types of instrument and borrower) showsinteresting...

This study quantifies the importance of a Global Financial Cycle (GFCy) for capital flows. We use capital flow data dis-aggregated by direction and type between 1990Q1 and 2015Q5 for 85 countries, and conventional techniques, models and metrics. Since the GFCy is an unobservable concept, we use...

Most countries hold large gross asset positions, lending in domestic currency and borrowingin foreign. Thus, their balance sheets are exposed to nominal exchange rates. We argue thatwhen asset markets are incomplete, nominal exchange rate exposure allows countries topartially insure against...

This paper investigates the global macroeconomic consequences of falling oil prices due to the oil revolution in the United States, using a Global VAR model estimated for 38 countries/regions over the period 1979Q2 to 2011Q2. Set-identification of the U.S. oil supply shock is achieved through...

This paper investigates empirically the drivers of financial imbalances ahead of the global financial crisis. Three factors may have contributed to the build-up of financial imbalances: (i) rising global imbalances (capital flows), (ii) monetary policy that might have been too loose, (iii)...

Dark matter accounts for 83 percent of the matter in the universe and plays a central role in cosmology modeling. This paper argues that an analogous form of dark matter plays a similarly important role in international macroeconomics. Exchange-rate dark matter is invisible, but its existence...

This paper contrasts real exchange rate (RER) measures based on different deflators (CPI, GDP deflator, and ULC) and discusses potential implications for the link-or lack thereof-between RER and external balance. We begin by documenting patterns in the evolution of different measures of RERs,...

This paper has two objectives. First, it reviews the recent dynamics of global imbalances (both “flow” and “stock” imbalances), with a special focus on the shifting position of Latin America in the global distribution. Second, it examines the cross-country variation in external...

Milton Friedman argued that flexible exchange rates would facilitate external adjustment. Recent studies find surprisingly little robust evidence that they do. We argue that this is because they use composite (or aggregate) exchange rate regime classifications, which often mask very...
