Simon Rottenberg's seminal 1956 article in the Journal of Political Economy, 1956, is generally accepted as the starting point for the development of the economics of sport. While he recognised that certain features of professional sports leagues were unusual he saw little reason to treat this...

This paper introduces the dynamical framework which combines product and process innovations. The model contributes to the theoretical literature on innovations in two ways. First, it permits for the simultaneous dynamics of both types of innovations which is rarely considered in the literature....

Credence goods markets, such as those for car repairs and medical treatments, are generally characterized by an ex-ante and ex-post information asymmetry between the uninformed buyer and the informed seller. Previous literature demonstrates that efficiency and fraud in a monopolist credence...

This paper studies the question why patents for multi-product monopolies should be finite. The monopolist is developing new versions of the basic product continuously and simultaneously invests into the improvement of all the existing and newly created products, thus optimally managing both...

We consider a situation where an exhaustible-resource seller faces demand from a buyer who has a perfect substitute but there is a time-to-build delay for the substitute. We that find in this simple framework the basic implications of the Hotelling model (1931) are reversed: over time the stock...

We study an industry in which an upstream monopolist supplies an essential input at a regulated price to several downstream firms. Legal unbundling means that a downstream firm owns the upstream firm but this upstream firm is legally independent and maximizes its own upstream profits. We allow...

We analyze third degree price discrimination by an upstream monopolist to a continuum of heterogeneous downstream firms. The novelty of our approach is to recognize that customizing prices may be costly. As a consequence, partial price discrimination arises in equilibrium; in particular,we...

A method for dealing with monotonicity constraints in optimal control problems is used to generalize some results in the context of monopoly theory, also extending the generalization to a large family of principal-agent programs. Our main conclusion is that many results on diverse economic...

A monopoly that sells to brand-name loyal customers and to price-sensitive customers must decide whether to carry both name-brand and a private-label products and how much to charge. The monopoly may charge either more or less for the brand name if it carries a private label, and the price...

This paper quantifi es the effects of drug monopolies and low per-capita income on pharmaceutical prices in developing economies using the example of the antiretroviral drugs (ARVs) used to treat HIV. -- intellectual property rights ; international price discrimination ; TRIPS agreement ;...
