We provide three sets of variance decompositions on microeconomic international relative price data. The first shows that the overall distribution of absolute deviations from the Law of One Price (LOP) is dominated by cross-sectional variation in long-term averages, not by time-series variation...

We use a novel dataset of online prices of identical goods sold by four large global retailers in dozens of countries to study good-level real exchange rates and their aggregated behavior. First, in contrast to the prior literature, we demonstrate that the law of one price holds very well within...

Guided by a macroeconomic model in which non-energy commodity prices are endogenously determined, we apply a new factor-based identification strategy to decompose the historical sources of changes in commodity prices and global economic activity. The model yields a factor structure for commodity...

Does membership in a currency union matter for a country's international relative prices? The answer to this question is critical for thinking about the implications of joining (or exiting) a common currency area. This paper is the first to use high-frequency good-level data to provide evidence...

We provide a comprehensive account of the dynamics of eurozone countries from 2000 to 2012. We analyze private leverage, fiscal policy, labor costs and interest rates and we propose a strategy to separate the impact of credit cycles, excessive government spending, and sudden stops. We then ask...

Even well managed emerging market economies are exposed to significant external risk, the bulk of which is financial. At a moment's notice, these economies may be required to reverse the capital inflows that have supported the preceding boom. While capital flows crises are sudden nonlinear...

One of the most serious problems that a central bank in an emerging market economy can face, is the sudden reversal of capital inflows. Hoarding international reserves can be used to smooth the impact of such reversals, but these reserves are seldom sufficient and always expensive to hold. In...

The 1990s emerging-markets crises were characterized by sudden reversals in inflows of foreign capital followed by unusually large declines in current account deficits, private expenditures, production, and prices of nontradable goods relative to tradables. This paper shows that these Sudden...

Dynamic Stochastic General Equilibrium (DSGE) models are often solved and estimated under specific assumptions as to whether the exogenous variables are difference or trend stationary. However, even mild departures of the data generating process from these assumptions can severely bias the...
