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

Large distance and border effects on trade flows in some industries may result from the collusive division of geographic markets. In the Brazilian cement industry, traditional gravity equations fit the data well, yet limited regional flows are due to firms' strategic behaviour. Thanks to a...

How consumers might switch from gasoline and diesel to alternative energy sources is not known, since the availability of alternatives is currently very limited. To bridge this gap, we exploit exogenous variation in ethanol prices at Brazil's pumps and uncover substantial consumer heterogeneity...

Anti-competitive mergers may be held up when outside firms respond pro-competitively. I examine the profitability of cross-border mergers by embedding a class of oligopoly models-where mergers are anti-competitive and actions are strategic substitutes-in a sequential merger game, cast in a...

This paper seeks to uncover why the pattern of equilibria in sequential merger games of a certain type is similar across a fairly wide class of models much studied in the literature. By developing general conditions characterising each element of the set of possible equilibria, I show that the...

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...

Brazil's established soft-drink firms recently lost ground to multiple low-price entrants, with small-scale operations and minimal advertising. While incumbents attributed such undercutting to entrants' lower costs from non-compliance with the law, 'generics' counterargued that incumbents' high...
