We study reactions to entry in a Cournot model, contrasting the case where firms are endowed with unchangeable technologies against that where technologies are flexible. By the latter we mean that firms can change the installed production technique at zero cost (fully flexible technologies). We...

To study the coexistence of two different ownership forms within an industry, I develop a simple model of competition between one forprofit and one nonprofit firm. The two firms have different objectives and face different constraints due to their choice of ownership status. Assuming...

We consider a heretofore unexplored explanation for why platforms, such as Internet service providers and mobile-phone networks, offer plans with download limits: through one of two mechanisms, doing so causes the providers of the content consumer purchase to either reduce their prices or...

Data-driven AI pricing algorithms in on-line markets collect consumer information and use it in their pricing technologies. In the simplest symmetric Hotelling's model such technologies reduce prices and profits. We extend Hotelling's model with vertically diferentiated products, cost...

Here we reproduce the table of contents and the introductory chapter to our book of related essays published by Edward Elgar. These essays deal with the important implications of allowing for the distribution of goods in characteristic space and of producers in geographic space. Although several...

Classic artificial intelligence (Q-learning) algorithms have been capable of consistently learning supra-competitive pricing strategies in infinitely repeated Nash-Bertrand pricing games without human communication. Such algorithms have been able to converge due to the temporal correlation of...

Successful upstream collusion must satisfy both the incentive constraint (keeping cartel members in line) and the compensation constraint (preventing lawsuits from downstream firms). Our analysis shows that there is a non-monotonic and inverted U-shaped relationship between cartel incidence and...

This paper studies the role of buyer market power in determining the response of international prices to exchange rate changes (i.e., exchange rate pass-through). Using a novel dataset of the universe of Colombian export transactions that links Colombian exporters (sellers) to their foreign...

Empirical studies have found that enhanced foreign competition can encourage or discourage innovation. To address this relationship, I examine a market structure in which a small number of large multi-product oligopolists compete with a large number of small single-product firms in the same...

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...
