The intrinsic comparative statics properties of a general rate-of-return regulated, profitmaximizing model of a monopolist facing a command-and-control pollution constraint are derived. Recent advances in the theory of comparative statics are used to derive the basic comparative statics of the...

El Real Decreto 222/2008 estableció un nuevo modelo retributivo para la actividad de la distribución de la energía eléctrica en España. En esta normativa se contempla la utilización de un modelo de red para fijar algunos de los parámetros que intervienen en la fórmula retributiva de cada...

When consumers' willingness-to-pay increases by a uniform amount, the change in the resulting monopoly price is generally indeterminate. Our analysis identifies sufficient conditions on the underlying demand curve which predict both the sign and the magnitude of the resulting price change.

Motivated by the failure of competition to emerge after the natural gas market in the Czech Republic was liberalized, I explore the impact of natural gas storage ownership and upstream competition on the downstream level. I extend standard Cournot models to understand current and likely future...

The literature on the effects of market concentration in platform industries or two-sided markets often compares the competitive outcome against a benchmark. This benchmark is either the “joint management” solution in which one decision maker runs all platforms or a “pure” monopoly with...

We propose both a monopoly and a duopoly model of a two-sided market. Both settings are fully comparable, as we impose a homogeneous good produced at zero costs without capacity constraints, as well as identical parameterization of market sizes. We determine the duopoly equilibrium and the...

The authors explain why the elementary logic of rate-of-return regulation generates not the competitive outcome but the monopoly outcome. Within the framework of the "passive regulator" that this logic entails, public regulation cannot alter the monopoly outcome, but can only change the form in...

Gegenstand der vorliegenden Studie ist die optimale Regulierung des Betriebs von Netzwerken, die die Charakteristika eines natürlichen Monopols aufweisen. Während bei der Nutzung solcher Netzwerke Wettbewerb zwischen verschiedenen Anbietern netzbasierter Dienstleistungen errichtet werden kann,...

We analyze the optimal location choice of a monopolistic firm that operates two platforms on a two-sided market. We show that the optimal platform locations are equivalent to the one-sided benchmark if both sides are either restricted to single- or multi-homing. In the mixed case (one side...

We study the issue of integrating real and financial decisions in a monopoly firm with risk-averse decision-makers. To that end, we combine the decisions of the firm and of the shareholders in a very simple but robust model, with uncertainty in the real market and CARA preferences. We show the...
