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...

Slotting allowances are fees paid by manufacturers to get access to retailers' shelf space. Both in the USA and Europe, the use of slotting allowances has attracted attention in the general press as well as among policy makers and economists. One school of thought claims that slotting allowances...

The unprecedented access of firms to consumer level data not only facilitates more precisely targeted individual pricing but also alters firms' strategic incentives. We show that exclusive access to a list of consumers can provide incentives for a firm to endogenously assume the price leader's...

We study the effect of a merger between two Dutch supermarket chains to assess its effect on the depth as well as composition of assortment. We adopt a difference-in-differences strategy that exploits local variation in the merger’s effects, controlling for selection on observables through a...

We study the relationship between regulatory regimes and pharmaceutical firms' pricing strategies using a unique policy experiment from Norway, which in 2003 introduced a reference price (RP) system called "index pricing" for a sub-sample of off-patent pharmaceuticals, replacing the existing...

Policy makers use reference pricing to curb pharmaceutical expenditures by reducing coverage of expensive branded drugs. In a theoretical analysis we show that the net effect of reference pricing is generally ambiguous when accounting for entry by generic producers. Reference pricing shifts...

We study competition among a score of firms participating in an online market for a commodity computer component. Firms were able to adjust prices continuously; prices determined how the firms were ranked and listed (lowest price listed first), with better ranks contributing to firms' sales....

We study price dynamics for computer components sold on a price-comparison website. Our fine-grained data—a year of hourly price data for scores of rival retailers—allow us to estimate a dynamic model of competition, backing out structural estimates of managerial frictions. The estimated...

The New Trade Theory predicts that international trade lowers prices for consumers and expands the choices available to them. This study shows that both predictions may no longer hold once adjustments in the retail sector are taken into account. I present a new model of retailing in general...

We examine the profitability of personalized pricing policies that are derived using different specifications of demand in a typical retail setting with consumer-level panel data. We generate pricing policies from a variety of models, including Bayesian hierarchical choice models, regularized...
