One Merger, Three Verdicts: Market Definition, Box-Office Shares, and Bargaining Power

The Paramount–Warner merger produced three sharply different regulatory responses. The Department of Justice cleared it. The European Commission cleared it with one narrow remedy. A coalition of states sued to stop it. The apparent disagreement concerns market definition: should competition be measured among anticipated blockbusters, all wide-release films, or a broader group that includes independents and newer theatrical suppliers? But even if the states establish a narrow blockbuster market, another question remains. What should each studio’s market share measure? Historical box-office receipts capture commercial success, audience demand, and the strength of a studio’s past slate. They do not tell us directly which distributor is the next best alternative for an exhibitor, how often Paramount and Warner constrain each other in negotiations, or how much bargaining leverage theaters would lose post-merger. This episode examines the difference between defining a market and measuring competition within it—and why the arithmetic of HHI can be much simpler than its economic interpretation.Read the full article and graphic analysis: https://blog.econworks.com/p/one-merger-three-answers?r=562wriExplore more visual economics content: https://econworks.comYouTube: https://www.youtube.com/@EconWorks-d3eSubstack: https://blog.econworks.com This is a public episode.
