How can firms profitably give away free products? This paper provides a novel answer and articulates tradeoffs in a space of information product design. We introduce a formal model of two-sided network externalities based in textbook economics - a mix of Katz & Shapiro network effects, price...

Although antitrust courts sometimes stress the competitive process, they have not deeply explored what that process is. Inspired by the theory of the core, we explore the idea that the competitive process is the process of sellers and buyers forming improving coalitions. Much of antitrust can be...

Reinforcement learning (RL) based pricing algorithms have been shown to tacitly collude to set supra-competitive prices in oligopoly models of repeated price competition. We investigate the impact of ranking systems, a common feature of online marketplaces, on algorithmic collusion in prices. We...

Drawing upon the science of complexity we propose a network-centric, complex-systems internationalization (NCCSI) perspective of firm internationalization that can help us understand observed patterns of internationalization that are difficult to explain using traditional theories. While...

In this paper, we combine the strategic delegation approach of Fershtman-Judd-Sklivas with contets. The results show that besides a symmetric equilibrium there also exist asymmetric equilibria in which one owner induces pure sales maximization to his manager so that all the other firms drop out...

We study experimentally how entry into a market with uncertain capacity is affected by the type of information potential entrants have available. Our focus is on behavior in a two-market entry game. In the risky information market there are two possible market capacities, both known to occur...

A robust result in the literature on strategic incentives pioneered by Fershtman and Judd (1987), Sklivas (1987), and Vickers (1985) is that under quantity competition firm owners induce their managers to make aggressive quantity choices in the product market. We revisit this result in a...

This paper examines the relationship between competition and price discrimination in the market for mailing lists. More specifically, we examine whether sellers are more likely to segregate consumers by offering a menu of quality choices (second-degree price discrimination) and/or offering...

Recent work in macroeconomics argues that firm market power dramatically increased since the 1980s. Using financial statement data, I find that public firm markups increased only modestly over this time period, and are within historical variation. These estimates improve on earlier work by...

The study generalizes the structure of network effects that is the defining feature of platforms. By adapting graph theory and the micro-foundation from Ballester et al. (2006), I discuss the monetization strategy for platforms that confront the demand with pair-wised network effects (e.g....
