We consider the regulation of a monopoly facing consumers that may evade payments, an important issue in public utilities. To maximize total surplus, the regulator sets the price and socially costly transfers, ensuring that the monopoly breaks-even. With costly effort, the firm can deter...

This Article advances a novel theoretical model for assessing policy interventions against Facebook. As prosecutors barrel forward against digital platforms, soon it will fall upon courts and, eventually, regulators to devise remedies. We argue that any sensible solution must include...

The critical literature on monopolies, from monopoly capital to recent contributions, focuses on the organization that concentrates either market power, capital or property rights. I complement this literature by conceptualizing monopolies as a power relation, which enables me to integrate...

This paper develops a theory of oligopoly and markups in general equilibrium. Firms compete in a network of product market rivalries that emerges endogenously out of the characteristics of the products and services they supply. My model embeds a novel, highly tractable and scalable demand system...

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...

While private monopolists are generally assumed to maximize profits, the goals of public enterprises are less well known. Using the example of Pennsylvania's state liquor retailing monopoly, we use information on store location choices, prices, wholesale costs, and sales to uncover the goals...

"Double marginalization" and "Elimination of Double marginalization" are catch-phrases commonly used in the IO literature. In this note, I trace back the origin of the idea to Chapter IX, on complementary goods monopolies, of Cournot (1838). Through the years Cournot's contribution remained a...
