The Impact of Private Label Introduction on Assortment, Prices, and Profits of Retailers
Ma, Meilin; Siebert, Ralph - 2021
We study how the introduction of private-label brands (PLs) affects retailers’ prices, demand, and profits, explicitly accounting for assortment adjustments of national brands (NBs) in retail stores. Using a detailed dataset on the U.S. beef market, we find that, when PLs are added to the...

Optimization Over Graphs
Kwon, Suehyun - 2019
This paper defines isomorphism for network formation that is not mathematically isomorphic. Once the pattern of network formation is characterized, one can test for (i) location fixed effects, (ii) heterogeneity, (iii) private information allowing for long-term contracts. The paper provides...

Estimating the Costs of Standardization : Evidence from the Movie Industry
Caoui, El Hadi - 2020
This paper studies the decentralized adoption of a technology standard when network effects are present. If the new standard is incompatible with the current installed base, adoption may be inefficiently delayed. I quantify the magnitude of "excess inertia" in the switch of the movie...
