Abstract

We develop a model of successive oligopolies with endogenous entry, allowing for varying degrees of product differentiation and entry costs in both markets. We show that downstream conditions dominate the overall profitability of the two-tier structure while upstream conditions mainly affect the distribution of profits. We analyze how two-part tariffs and resale price maintenance shape the endogenous market structure and study their welfare effects. In contrast to previous literature, we find that welfare under linear prices can be larger than under twopart tariffs although the latter avoids double marginalization. This is because linear prices induce more downstream market entry.
