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....

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...

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...

Random choices of prices and product characteristics can be used by a contestable monopolist to deter entry and fully extract the monopoly rent. We develop this idea in a model of Bertrand price competition. In equilibrium, one firm enters the market and makes choices that are unpredictable to...

We discuss network neutrality regulation of the Internet in the context of a two-sided market model. Platforms sell broadband Internet access services to residential consumers and may set fees to content and application providers on the Internet. When access is monopolized, cross-group...

We suppose that guns or firearms are subject to an anticipated future buyback program undertaken by the government. A simple linear demand durable-goods monopoly model is then analyzed where the durable-good manufactured is a firearm that lasts for two-periods. The model is calibrated so that...

The Commission was asked to review the National Third Party Access Regime for Natural Gas Pipelines. The review sought to assess the benefits and costs of the Regime, including its effects on investment. The Commission’s preliminary findings were released for public comment in December 2003...

A monopoly that sells to brand-name loyal customers and to price-sensitive customers must decide whether to carry both name-brand and 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...

Textbooks present the three ‘degrees’ of price discrimination as a sequence of independent pricing methods. These textbook treatments consequently provide inadequate insight as to when a firm might adopt a particular pricing strategy. The paper describes an informationbased taxonomy of price...
