We show that, in general, consistent estimates of cost pass-through are not obtained from reduced-form regressions of price on cost. We derive a formal approximation for the bias that arises even under standard orthogonality conditions. We provide guidance on the conditions under which bias may...

The two central pricing rules contained in most antitrust laws are prohibitions of below-cost pricing and prohibitions of discriminatory pricing. This article shows that the rule against discriminatory pricing may actually induce firms to charge exclusionary below-cost prices, even in the...

Harrington (2004) shows that conspirators can have incentives to maintain high prices after the cartel’s discovery to reduce damages they are likely to pay. We exploit the existence of a discovered retail gasoline price-fixing cartel in the province of Quebec to test this theory. The empirical...

This note investigates the effects of a large horizontal merger on the shape of the 1-to-12 h price menus offered by parking garages in Paris. The merger caused low-end prices to increase proportionally more than high-end prices. This results in larger discounts on longer hours and hence in more...

We analyze a model of competition in non-linear pricing under complete information. Among the equilibria of the game, we focus on the truthful equilibrium and the equilibrium that is Pareto dominant for the firms. These coincide when there are only two firms, but differ with three or more firms....

This paper investigates the size of penalties required to deter cartel formation. Allowing the penalty to be increasing in duration within the infinitely repeated game framework, penalties do not need to be as severe as previous research would suggest.

Laitinen (1980) derives an input allocation model for a multiproduct firm that first maximizes revenue and second maximizes profit. While theoretically elegant, the model has never been formulated empirically because of the complexity of the model’s price-deflated terms. This paper derives the...

This paper studies the impact of relative performance evaluation (RPE) on the equilibrium locations in a Hotelling model with quadratic transportation cost. It is shown that equilibrium location varies from maximum differentiation to minimum differentiation, depending upon the relative strength...

I develop a semi-structural approach to identify network effects on two-sided monopoly platforms without data on prices and quantities. When total revenue data is available, the test is sufficient. When separate revenue data is available on the two sides, the test is both necessary and sufficient.

We propose and test hypotheses about three endogenous mechanisms that may be driving the observed network structure of producers’ markets. We use data that we have collected on collaborative network ties among producers. Estimates of Exponential Random Graphs Models (ERGM) support our hypotheses.
