|September 2018||Belief Disagreement and Portfolio Choice|
with Maarten Meeuwis, Jonathan A. Parker, Antoinette Schoar: w25108
Using a proprietary dataset of the portfolio holdings of millions of US households, we document how agents who believe in different models of the world update their beliefs heterogeneously in response to a public signal. We identify households ex ante that hold different models of the world using political party affiliation (probabilistically inferred from zip code), and our public signal is the unexpected outcome of the US national election of 2016. Relative to Democrats, Republican investors actively increase the equity share and market beta of their portfolios following the election. The rebalancing is due to a small share of investors making large adjustments. We conclude that this behavior is driven by belief heterogeneity because of extensive controls for differential hedging needs o...
|August 2013||Informational Rigidities and the Stickiness of Temporary Sales|
with Eric Anderson, Benjamin A. Malin, Emi Nakamura, Jón Steinsson: w19350
We use unique price data to study how retailers react to underlying cost changes. Temporary sales account for 95% of price changes in our data. Simple models would, therefore, suggest that temporary sales play a central role in price responses to cost shocks. We find, however, that, in response to a wholesale cost increase, the entire increase in retail prices comes through regular price increases. Sales actually respond temporarily in the opposite direction from regular prices, as though to conceal the price hike. Additional evidence from responses to commodity cost and local unemployment shocks, as well as broader evidence from BLS data reinforces these findings. We present institutional evidence that sales are complex contingent contracts, determined substantially in advance. We show th...

|June 2013||Multichannel Spillovers from a Factory Store|
with Yi Qian, Eric Anderson: w19176
We study how the opening of a factory store impacts a retailer's demand in its other channels. It is possible that a factory store may damage a retailer's brand image and lead to substitution away from its higher quality core channels. Alternatively, the opening of a factory store may have positive effects as it may attract new buyers and serve as a form of brand advertising. In this paper, we use a natural experiment that arises from a retailer introducing a factory store in 2002. We analyze data that spans all customers and all channels from 1995 to 2007. This allows for careful pre and post analysis of the factory store opening. We find that the introduction of the factory store led to substantial positive spillovers to the core channels that lasted for multiple years. Customers purch...
|May 2007||"The Best Price You'll Ever Get" The 2005 Employee Discount Pricing Promotions in the U.S. Automobile Industry|
with Meghan R. Busse, Florian Zettelmeyer: w13140
During the summer of 2005, the Big Three U.S. automobile manufacturers offered a customer promotion that allowed customers to buy new cars at the discounted price formerly offered only to employees. The initial months of the promotion were record sales months for each of the Big Three firms, suggesting that customers thought that the prices offered during the promotions were particularly attractive. In fact, such large rebates had been available before the employee discount promotion that many customers paid higher prices following the introduction of the promotions than they would have in the weeks just before. We hypothesize that the complex nature of auto prices, the fact that prices are negotiated rather than posted, and the fact that buyers do not participate frequently in the market ...
