Talk on February 19, 2021: Algorithmic Pricing and Market Competition

Our next Economics & Strategy Talk hosted Professor Joseph Harrington from The Wharton School at the University of Pennsylvania who presented “Algorithmic Pricing & Market Competition” on February 19, 2021.

As a result of Big Data and AI, firms can condition prices on high frequency data, tailor prices to narrow submarkets, and more effectively learn in order to discover the most profitable pricing rules. While there are potential efficiency benefits from these advances, concerns have been raised about possible consumer harm. Enhanced price discrimination fueled by customer-specific data may result in a transfer of surplus from consumers to firms. Automated pricing could make markets more efficient by increasing the speed of response to demand and supply changes but could also undermine price competition. Learning algorithms could discover more profitable pricing rules but that could be because they facilitate collusion. Competition authorities have expressed concern with the growing role of algorithmic pricing and there is an active policy debate as to whether legal and enforcement regimes are equipped to deal with it. This talk reviewed the emergence and effect of algorithmic pricing in a variety of markets including pricing by platforms such as Uber, bidding at Google sponsored search auctions by digital marketing agencies, and the use of a third party’s pricing algorithm such as at Amazon Marketplace and in retail gasoline markets. Also explored was a recent case in which firms colluded by coordinating their pricing algorithms and the prospect of collusion autonomously achieved by AI.
