This paper analyzes the implications of heterogeneity in price setting for the real effects of monetary shocks. Starting from otherwise standard sticky price and sticky information models, I introduce ex-ante heterogeneity in terms of price setting frictions, and compare the resulting dynamics...

We describe a strategy for the analysis of experimentally derived gene expression signatures and their translation to human observational data. Sparse multivariate regression models are used to identify expression signature gene sets representing downstream biological pathway events following...

Given the frequency of price changes, the real effects of a monetary shock are smaller if adjusting firms are disproportionately likely to be ones with prices set before the shock. This selection effect is important in a large class of sticky-price models with time-dependent price adjustment. We...

In September 2008, a six-year-old article about the 2002 bankruptcy of United Airlines' parent company resurfaced on the Internet and was mistakenly believed to be reporting a new bankruptcy filing by the company. This episode caused the company's stock price to drop by as much as 76% in just a...

We develop a multi-sector sticky-price DSGE model that can endogenously deliver differential responses of prices to aggregate and sectoral shocks. Input-output production linkages induce across-sector pricing complementarities that contribute to a slow response of prices to aggregate shocks. In...

Loss aversion has been used to explain why a high equity premium might be consistent with plausible levels of risk aversion. The intuition is that the first-order-different utility impact of wealth gains and losses leads loss-averse investors to behave similarly to investors with high risk...

The real effects of an imperfectly credible disinflation depend critically on the extent of price rigidity. We examine this interaction in a model with endogenous time-dependent pricing. Both the endogenous initial degree of price rigidity and changes in the duration of price spells during...

We estimate a multi-sector sticky-price model for the U.S. economy in which the degree of price stickiness is allowed to vary across sectors. For this purpose, we use a specification that allows us to extract information about the underlying cross-sectional distribution from aggregate data....
