The persistence of aggregate real exchange rates is a prominent puzzle, particularly since adjustment of international relative prices in microeconomic data is much faster. This paper finds that adjustment to the law of one price in disaggregated data is not just a faster version of the...

This paper analyzes how a model where goods are endogenously nontraded can help explain the relationship between the current account and real exchange rate fluctuations. We formulate a small open economy two-period model in which goods switch endogenously between being traded or nontraded. The...

This paper documents significant time-variation in the degree of global price convergence over the last two decades. In particular, there appears to be a general U-shaped pattern with price dispersion first falling and then rising in recent years, a pattern which is remarkably robust across...

Long-run cross-country price data exhibit a puzzle. Today, richer countries exhibit higher price levels than poorer countries, a stylized fact usually attributed to the “Balassa-Samuelson” effect. But looking back fifty years, or more, this effect virtually disappears from the data. What is...

We present evidence on the effects of large-scale asset purchases by the Federal Reserve and the Bank of England since 2008. We show that announcements about these purchases led to lower long-term interest rates and depreciations of the U.S. dollar and the British pound on announcement days,...

This paper derives a formula for the optimal forecast of a discounted sum of future values of a random variable. This problem reflects a preference for robustness in the presence of (unstructured) model uncertainty. The paper shows that revisions of a robust forecast are more sensitive to new...

We develop an overlapping generations model of the real estate market in which search frictions and a debt overhang combine to generate price persistence and illiquidity. Illiquidity stems from heterogeneity in agent real estate valuations. The variance of agent valuations determines how quickly...

We construct a 2 sector growth model with sector specific technology shocks where one sector produces intermediate goods while the other produces final goods. Theoretical restrictions from this model are used to compute the time series for sector-specific TFPs based solely on factor prices and...
