I begin by fitting traditional gravity equations to document that regional flows in the Brazilian cement industry exhibit gravity-like structure, with cement trade decaying sharply in distance traveled. I then show that this large distance effect owes to firms' strategic behavior over and above...

Consider a setting where threatened rather than actual import competition restrains a domestic oligopoly's prices. I show that not modeling the entry threat may underestimate the true degree of market power, as incumbents' blunted price responses to demand shocks resemble perfectly-competitive...

This paper argues that large distance and border effects on trade flows in some industries might be a result of the (explicitly or tacitly) collusive division of geographic markets. A simple spatial oligopoly setting demonstrates how goods can travel shorter distances, or trade between regions...

This paper demonstrates that when an industry faces potential entry and this threat of entry constrains pre-entry prices, cost and conduct are not identified from the comparative statics of equilibrium. In such a setting, the identifying assumption behind the well-established technique of...

Oligopoly theory suggests that anti-competitive mergers may be held up because firms outside the merger stand to increase profits at the expense of the merging firms (Stigler 1950). Against this backdrop, I examine the profitability of cross-border mergers by embedding a class of oligopoly...
