This Article studies the durapolist, the durable-goods monopolist. Durapolists have long argued that, unlike perishable-goods monopolists, they face difficulties in exercising market power despite their monopolistic position. During the past thirty years, economists have extensively studied the...

Many experts speculate that U.S. antitrust policy towards horizontal mergers has been too lenient. We estimate the price effects of Whirlpool's acquisition of Maytag to provide new evidence on this debate. We compare price changes in appliance markets most affected by the merger to markets where...

We investigate the accuracy of UPP as a tool in antitrust analysis when there are cost efficiencies from a horizontal merger. We include model-based, merger-specific cost efficiencies in a tractable manner and extend the standard UPP formulation to account for these efficiencies. The efficacy of...

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...

The unprecedented access of firms to consumer level data facilitates more precisely targeted individual pricing. We study the incentives of a data broker to sell data about a segment of the market to three competing firms. The segment only includes a share of the consumers in the market around...

We study competition in markets with significant transport costs and capacity constraints. We compare the cases of price competition and coordination in a theoretical model and find that when firms compete, they more often serve more distant customers that are closer to plants of competitors. By...

This article studies competition in markets with transport costs and capacity constraints. We compare the outcomes of price competition and coordination in a theoretical model and find that when firms compete, they more often serve more distant customers who are closer to the competitor's plant....

While price-fixing on platforms can attract severe enforcement action, as shown by the Amazon poster case, a more nuanced picture emerges regarding the fixing of prices for sellers by sharing economy platforms. This paper explores possible antitrust responses to such centralised platform-driven...
