A Beautiful Theory Falls to Ugly Data - Marginal REVOLUTION

Theory Briefing

  • The Coase Conjecture predicts durable-goods monopolists lose pricing power over time, but almost no real-world tests have ever been run.
  • This study is one of the first direct empirical tests of the conjecture, moving beyond a handful of lab experiments to actual market data.
  • The results suggest the theory's beautiful internal logic crumbles when confronted with messy real-world consumer and firm behavior.
