Analysis

This paper investigates the unintended consequences of regulation on market competition. It uses a real-world example of a ban on comparative price advertising in Chilean pharmacies to demonstrate how such a ban can shift an oligopoly from competitive loss-leader pricing to coordinated higher prices. The study highlights the importance of understanding the mechanisms that support competitive outcomes and how regulations can inadvertently weaken them.
