The existing defect of the legal field in form inconsistency norms that make it up, gives rise to inconsistency, imbalance main social regulator relations. Building normative material without analysing need create a separate regulator, as well obligation establish relationship with norms, determined significance such study. definition competition is an object scientific research quite often. Ho...

We analyze costly quality disclosure with horizontally differentiated products under duopoly and monopoly, and characterize the effect of competition on disclosure and welfare. We show that expected disclosure is higher under monopoly than under duopoly, and the welfare comparison depends on the level of disclosure cost: when the disclosure cost is low, welfare is higher under monopoly than duo...

This paper explores tying in the situation where a multi-product firm without monopoly power competes against several single-product firms. It considers two independent markets: one for a horizontally differentiated good, the other for a homogeneous good. As opposed to the widely accepted opinion that tying may be profitable only in the case of monopoly power, it is shown that under reasonable ...

An upstream monopoly that provides a new good to a downstream oligopoly might prefer to sell to a single rather than to multiple downstream firms. For example, Apple initially sold its iPhone through one vendor. If a monopoly uses a single vendor, the government may impose a mandatory universal distribution (MUD) requirement that forces the monopoly to sell to all downstream vendors. However, i...

Economists have long recognized that regulation is an imperfect solution to market failure. Do the inefficiencies of regulation outweigh the inefficiencies of market failure? In this paper, we develop a stylized model of a monopolist offering two services, one more widely demanded than the other. We compare aggregate surplus from unregulated monopoly with aggregate surplus from a median voter m...

The monopoly-supported universal service obligation (USO) is usually defended on the grounds that the monopoly allows for cross-subsidy in letter services that in turn allows universal access to a service of great importance to all. This paper argues that letter delivery (as opposed to other services that may be provided by post offices) is not in universal demand in poor countries, that the si...

We consider a robust version of the classic problem of optimal monopoly pricing with incomplete information. In the robust version, the seller faces model uncertainty and only knows that the true demand distribution is in the neighborhood of a given model distribution. We characterize the pricing policies under two distinct decision criteria with multiple priors: (i) maximin utility and (ii) mi...
