Dilemma not Trilemma
There is a global financial cycle in capital flows, asset prices and in credit growth. This cycle co moves with the VIX, a measure of uncertainty and risk aversion of the markets. Asset markets in countries with more credit inflows are more sensitive to the global cycle. The global financial cycle is not aligned with countries' specific macroeconomic conditions. Symptoms can go from benign to large asset price bubbles and excess credit creation, …
Financial Flows and the International Monetary System
We review the findings of the literature on the benefits of international financial flows and find that they are quantitatively elusive. We then present evidence on the existence of a global cycle in gross cross border flows, asset prices and leverage and discuss its impact on monetary policy autonomy across different exchange rate regimes. We focus in particular on the effect of US monetary policy shocks on the UK's financial conditions
One TV, One Price
We study television prices across European countries and regions. Quality as measured by observable characteristics of televisions accounts for a large share of the international dispersion in prices. Rich economies tend to consume higher‐quality goods, but sizeable international price differentials exist even for identical televisions. The valuation of brands differs significantly across borders. EMU countries display lower price dispersion but …
International Financial Adjustment
We explore the implications of a country's external constraint for the dynamics of net foreign assets, returns, and exchange rates. Deteriorations in external accounts imply future trade surpluses (trade channel) or excess returns on the net foreign portfolio (valuation channel). Using a new data set on U.S. gross external positions, we find that stabilizing valuation effects contribute 27 percent of the cyclical external adjustment. Our approach…
Globalization and Emerging Markets
We analyze the effects of financial and trade globalization on the likelihood of financial crashes in emerging markets. While trade globalization always makes crashes less likely, financial globalization may make them more likely, especially when trade costs are high. Pessimistic expectations can be self-fulfilling and lead to a collapse in demand for goods and assets. Such a crash comes with a current account reversal and drops in income and inv…

PPP Strikes Back
Financial Globalization and Emerging Markets
We analyze the impact of financial globalization on asset prices, investment and the possibility of crashes driven by self-fulfilling expectations in emerging markets. In a two-country model with one emerging market (intermediate income level) and one industrialized country (high income level), we show that liberalization of capital flows increases asset prices, investment and income in the emerging market. However, for intermediate levels of int…
