We use detailed micro data to document a causal response of local retail price to changes in house prices, with elasticities of 15%-20% across housing booms and busts. Notably, these price responses are largest in zip codes with many homeowners, and non-existent in zip codes with mostly renters....

Is monetary policy less effective at increasing real output during periods of high volatility than during normal times? In this article, I argue that greater volatility leads to an increase in aggregate price flexibility so that nominal stimulus mostly generates inflation rather than output...

Are there times when durable spending is less responsive to economic stimulus? We argue that aggregate durable expenditures respond more sluggishly to economic shocks during recessions because microeconomic frictions lead to declines in the frequency of households' durable adjustment. We show...

We estimate how durable expenditures respond to government spending shocks at different points in the business cycle using a nonlinear VAR approach that allows for the durable multiplier to vary smoothly with the state of the economy. We find strong evidence that the aggregate durable spending...

How do import prices respond to exchange rate changes, and does this response vary across products or across time? We document two new and related facts: 1. Individual items with high price change variance have greater exchange rate pass-through. 2. During times when the cross-sectional variance...

Business cycle models typically abstract from the distinction between durable and non-durable consumption. However, in the 2007 recession, durable expenditures fell by three times as much as GDP while non-durable expenditures fell by slightly less than GDP. We show that simple extensions of...

I show that the cross-sectional standard deviation of individual price changes in the BLS CPI database is countercyclical and comoves strongly with the frequency of price adjustments. Standard Ss models with only first moment shocks cannot explain these facts. Adding a second moment...

We examine the quantitative impact of the Federal Reserve's mortgage-backed securities (MBS) purchase program. We focus on how much of the recent decline in mortgage interest rate spreads can be attributed to these purchases. The question is more difficult than frequently perceived because of...
