This paper analyses the quality provision of interrelated market firms under different market structures both theoretically and empirically. A theoretical model is built, where a media firm offers newspapers in a primary market and advertising space in the secondary market. Furthermore, the...

We extend the models in ("Competition in two-sided markets" of Armstrong (2006, Rand Journal of Economics) by adding within-group externalities. In the monopoly and duopoly cases, positive within-group externalities reduce the price of the own group. Negative externalities have an opposite price...

Motivated by recent controversies surrounding the role of commercial lenders in microfinance, and calls for regulation of the sector, we analyze borrower welfare under different market structures, considering a benevolent non-profit lender, a for-profit monopolist, and a competitive credit...

"Two-sided" markets have two different groups of customers that businesses have to get on board to succeed - there is a "chicken-and-egg" problem that needs to be solved. These industries range from dating clubs (men and women), to video game consoles (game developers and users), to credit cards...

In this paper I set forth an antitrust remedy for the oligopolistic pricing problem. Oligopoly pricing resembles a repeated prisoners' dilemma game. Each firm has an incentive to moderately lower its price and thus increase its sales at its competitors' expense. However, each firm knows that its...

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...
