Editor’s Note: In this edition we review two papers by leading government economists, past, present, and perhaps future. The first paper, by Dennis Carlton and Ken Heyer, takes a cautious policy approach to single-firm conduct based on theory, empirical evidence, and “considerations of administrability and consistency with general and widely held presumptions” and sets out four “underlying principles” that should govern policy toward single-firm conduct. The second paper, on the role of market concentration in modern economic analysis of horizontal mergers, is by Jonathan Baker, in which he explains how market concentration can sensibly be used for merger analysis.
