This article studies competition in markets with transport costs and capacity constraints. We compare the outcomes of price competition and coordination in a theoretical model and find that when firms compete, they more often serve more distant customers who are closer to the competitor's plant....

We analyze the effects of structural remedies on merger activity in a Cournot oligopoly when the Antitrust Agency (AA) cannot observe a proposed merger's efficiency type. Provided the AA follows a consumer surplus standard, an efficient merger type is doomed to over-fix with its divestiture...

This paper experimentally analyzes the cartel coordination challenge induced by the discrimination of cartel ringleaders in leniency policies. Ringleaders often take a leading role in the coordination and formation of a cartel. A leniency policy which grants amnesty to all whistleblowers except...

Unlike most retrospective merger studies that only focus on price effects, we also estimate the impact of a merger on product variety. We use an original dataset on Dutch supermarkets to assess the effect of a merger that was conditionally approved by the Dutch Competition Authority (ACM) on...

We analyze oligopolistic third-degree price discrimination relative to uniform pricing, when markets are always covered. Pricing equilibria are critically determined by supply-side features such as the number of firms and their marginal cost differences. It follows that each firm's Lerner index...

Many cartels are formed by individual managers of different firms, but not by firms as collectives. However, most of the literature in industrial economics neglects individuals' incentives to form cartels. Although oligopoly experiments reveal important insights on individuals acting as firms,...

This paper argues that it cannot be taken for granted that any merger that raises consumer surplus also increases social welfare. We assume a Cournot model with homogeneous goods, linear demand, and constant marginal costs, to show that a merger can raise consumer surplus while harming social...

We present a model to explain why a manufacturer may impose a minimum resale price (min RPM) in a successive monopoly setting. Our argument relies on the retailer having non-contractible choice variables, which could represent the price of a substitute good and/or the effort the retailer exerts...

We analyze the welfare effects of structural remedies on merger activity in a Cournot oligopoly if the antitrust agency applies a consumer surplus standard. We derive conditions such that otherwise price-increasing mergers become externality-free by the use of remedial divestitures. In this...

We analyze the efficiency defense in merger control. First, we show that the relationship between exogenous efficiency gains and social welfare can be non-monotone. Second, we consider both endogenous mergers and endogenous efficiencies and find that merger proposals are largely aligned with a...
