|March 2018||Markups Across Space and Time|
with Sergio Rebelo, Arlene Wong: w24434
In this paper, we provide direct evidence on the behavior markups in the retail sector across space and time. Markups are measured using gross margins. We consider three levels of aggregation: the retail sector as a whole, firm-level data, and product- level data. We find that: (1) markups are relatively stable over time and mildly procyclical; (2) there is large regional dispersion in markups; (3) there is a positive cross-sectional correlation between local income and local markups; and (4) differences in markups across regions are explained by differences in assortment, not by deviations from uniform pricing. We propose an endogenous assortment model that is consistent with these facts.
|August 2013||Informational Rigidities and the Stickiness of Temporary Sales|
with Benjamin A. Malin, Emi Nakamura, Duncan Simester, 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, Duncan Simester: 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...
