We present evidence of disintermediation---a notoriously challenging task---in a European cleaning platform's transaction data between April 2016 and February 2020. In short, we demonstrate that a cleaner's leaving the platform is typically accompanied by unusually many customers' also leaving...

Spoilage, expiration, damage due to employee/customer handling, employee theft, and customer shoplifting usually are not reflected in inventory records. As a result, records often report phantom inventory, that is, units of good not available for sale. We derive an optimal polynomial‐time...

We propose a simple explanation for price rigidity in perishable groceries: inventory record inaccuracy (IRI). We build our argument in two steps. First, we tailor Gallego and Van Ryzin’s (1994) revenue management model to perishable groceries by adding an inventory waste process,...

We present analytical and empirical arguments that competition over a homogeneous service forces electric scooter firms to over-supply scooters. First, using scooter deployment and rides data from multiple sources (scooter firms' application programming interfaces, cities' transportation...

We use the adoption of electronic shelf labels (ESLs) by an international grocery retailer in 2015 to identify the effects of physical menu costs (i.e., labor and material costs of price adjustment) on retail performance. We find that the installation of ESLs increased gross margins...

We develop a structural model of firms' bidding behavior in simultaneous first-price auctions with linkages across items, and apply the model to procurement auctions held by Minnesota's Department of Transportation (MnDOT). Each year, MnDOT holds simultaneous first-price auctions to procure road...

We study the supply chain implications of dynamic pricing. Specifically, we estimate how reducing menu costs---the operational burden of adjusting prices---would affect supply chain volatility. Fitting a structural econometric model to data from a large Chinese supermarket chain, we estimate...

We build a structural econometric model of pricing substitutes with menu costs and apply it to quasi-experimental data to estimate the share of physical menu costs (material and labor costs of price adjustment) in total menu costs. The data comes from the adoption of electronic shelf labels...
