Many technology industries are characterized by relatively high levels of industry concentration, with one or a few firms holding significant market share. This has sparked alarm among some who assert that such concentration is anti-consumer and call for more aggressive antitrust enforcement. Yet antitrust scholars have shown that in many cases the concentration helps consumers and spurs economic growth.
