|September 2019||Exposure to Daily Price Changes and Inflation Expectations|
with Francesco D’Acunto, Ulrike Malmendier, Michael Weber: w26237
We show that, to form aggregate inflation expectations, consumers rely on the price changes they face in their daily lives while grocery shopping. Specifically, the frequency and size of price changes, rather than their expenditure share, matter for individuals' inflation expectations. To document these facts, we collect novel micro data for a representative US sample that uniquely match individual expectations, detailed information about consumption bundles, and item-level prices. Our results suggest that the frequency and size of grocery-price changes to which consumers are personally exposed should be incorporated in models of expectations formation. Central banks' focus on core inflation---which excludes grocery prices---to design expectations-based policies might lead to systematic mi...
|April 2018||Mortgage-Backed Securities and the Financial Crisis of 2008: a Post Mortem|
with Harald Uhlig: w24509
We examine the payoff performance, up to the end of 2013, of non-agency residential mortgage-backed securities (RMBS), issued up to 2008. We have created a new and detailed data set on the universe of non-agency residential mortgage backed securities, per carefully assembling source data from Bloomberg and other sources. We compare these payoffs to their ex-ante ratings as well as other characteristics. We establish seven facts. First, the bulk of these securities was rated AAA. Second, AAA securities did ok: on average, their total cumulated losses up to 2013 are 2.3 percent. Third, the subprime AAA-rated segment did particularly well. Fourth, later vintages did worse than earlier vintages, except for subprime AAA securities. Fifth, the bulk of the losses were concentrated on a smal...
|February 2016||The Aggregate Implications of Regional Business Cycles|
with Martin Beraja, Erik Hurst: w21956
Making inferences about aggregate business cycles from regional variation alone is diffcult because of economic channels and shocks that differ between regional and aggregate economies. However, we argue that regional business cycles contain valuable information that can help discipline models of aggregate fluctuations. We begin by documenting a strong relationship across US states between local employment and wage growth during the Great Recession. This relationship is much weaker in US aggregates. Then, we present a methodology that combines such regional and aggregate data in order to estimate a medium-scale New Keynesian DSGE model. We find that aggregate demand shocks were important drivers of aggregate employment during the Great Recession, but the wage stickiness necessary for them...
