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...

Some legal academics have claimed that ‘machine collusion’ – tacit collusion generated by self-learning pricing algorithms without human involvement - is a real threat that will go uncheck by current antitrust. Half a decade after these claims received wide publicity the only evidence are...

The purpose of this article is to analyze how the presence of a competitive fringe, composed by price taker firms, can affect the sustainability of collusive equilibria. Our starting point is that there exists a diffused misunderstanding about its strategical role as collusive minus factor. We...

We analyze competition between mobile operators in a repeated game framework focusing on the durability over time of the offered charge profile. In fact, customers and operators sign a contract that is usually enforced until the former decides to change it. The consequence is that anytime an...

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...

This paper studies how product differentiation affects substitution patterns and firms' markups in oligopolistic markets where products are differentiated over multiple attributes and consumers have linear-quadratic preferences. Under these assumptions, the cross-price elasticity between any two...

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...

Has the Euro created a more competitive market? Using a staggered difference-in-differences design we find that the Euro has increased firm-level market power between 23% and 30% after its adoption. This happens because deepening economic integration creates a stronger competitive environment...

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...

In July 2019, Graphic Packaging CEO Michael Doss was proposing a $600 million investment in a new machine to produce coated recycled board (CRB), a type of paper packaging used for consumer products (cups, cereal boxes, beverage boxes, etc.) that utilized recycled paper as an input. Graphic...
