First-mover advantage in an Internet-enabled market environment: conceptual framework and propositions

TL;DR: In this article, a conceptual framework that focuses on selected sources of first-mover advantage delineated in the extant literature and advance propositions concerning sources that will have a greater or lower effect in the Internet-enabled market environment (IME) relative to the physical market environment is presented.

Simultaneous versus Sequential Group-Buying Mechanisms

TL;DR: The analysis shows that the sequential mechanism leads to higher deal success rates and larger expected consumer surpluses and this result holds for a multiperiod extension and when the firm offers a price discount schedule with multiple breakpoints.

Outsourcing Tasks Online: Matching Supply and Demand on Peer-to-Peer Internet Platforms

TL;DR: It is found that supply is highly elastic: in periods when demand doubles, sellers perform almost twice as many tasks, prices hardly increase, and the probability of requested tasks being matched falls only slightly, implying that in markets where supply can accommodate demand fluctuations, growth relies on attracting buyers at a faster rate than sellers.

Pure Strategy Nash Equilibrium in a Group Formation Game with Positive Externalities

TL;DR: In this paper, the authors identify a domain of payoff functions in no spillover noncooperative games with positive externality which admit a pure strategy Nash equilibrium and prove the existence of Nash equilibria.
Journal ArticleDOI

Co-opetition Between Differentiated Platforms in Two-Sided Markets

TL;DR: It is found that technology improvements by the inferior platform do not significantly increase its profits, but can reduce opportunities for fruitful cooperation, since collaboration is less likely in markets with closely matched competitors.

Monopoly, quality, and regulation

TL;DR: In this paper, the authors argue that under regimes of monopoly and monopolistic competition, product characteristics (which are often endogenous variables) are not usually optimally set under the pressure of market forces, and that regulation is also beset with difficulties when price and quality are decision variables.

Critical Mass and Tariff Structure in Electronic Communications Markets

TL;DR: In this article, the authors developed an economic model that determines both the required critical mass size for startup and the ultimate expansion level of such a system and evaluated the effects of different pricing structures for the service under the assumption that users maximize benefits minus cost and a monopoly supplier maximizes profit.

Tax Analysis in an Oligopoly Model

TL;DR: In this article, the authors use the conjectural variations model of oligopoly to analyze the way in which the incidence of a tax depends upon the pattern of firm interaction and show that the errors that arise in excess burden calculations when incorrect assumptions on market structure are made.
