This paper demonstrates that sectoral heterogeneity itself--without any additional bells or whistles--has first-order implications for the transmission of aggregate shocks to aggregate variables in an otherwise standard DSGE model. The effects of sectoral heterogeneity on this transmission are...

We investigate the extent to which inflation targeting helps anchor long-run inflation expectations by comparing the behavior of daily bond yield data in the United Kingdom and Sweden--both inflation targeters--to that in the United States, a non-inflation-targeter. Using the difference between...

This paper reexamines wage and price dynamics in response to permanent shocks to productivity. We estimate a micro-founded dynamic general equilibrium (DGE) model of the U.S. economy with sticky wages and sticky prices using impulse responses to technology and monetary policy shocks. We utilize...

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...

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...

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...

Whether prices are pro- or counter-cyclical represents a major difference in the predictions of models that focus on aggregate demand shocks as the primary source of business cycle fluctuations, versus those that emphasize shocks to aggregate supply. Earlier studies have interpreted their...
