This paper analyzes competitive pricing policies by multiproduct firms facing heterogeneous buying patterns. We show that cross-subsidization arises when firms have comparative advantages on different products but are equally efficient overall: Firms earn a profit from multi-stop shoppers by...

The U.S. steel industry has long held that foreign subsidization and excess capacity has led to its long-run demise, yet no one has formally examined this hypothesis. In this paper, we incorporate foreign subsidization considerations into a model based on Staiger and Wolak's (1992)...

A primary function of trade policy is to restrict imports to benefit the targeted domestic sector. However, a well-established theoretical literature highlights that the form of trade policy (e.g., quotas versus tariffs) can have a significant impact on how much trade policy affects firms'...

Over the past decades, the steel industry has been protected by a wide variety of trade policies, both tariff- and quota-based. We exploit this extensive heterogeneity in trade protection to examine the well-established theoretical literature predicting nonequivalent effects of tariffs and...

We show that large retailers, competing with smaller stores that carry a narrower range, can exercise market power by pricing below cost some of the products also offered by the smaller rivals, in order to discriminate multi-stop shoppers from onestop shoppers. Loss leading thus appears as an...
