Theory Briefing

  • Profit margins carry useful price-vs-cost signals, but the RBA warns that simple 'greedflation' stories badly misread the data.
  • Markup theory shows margins can rise even without predatory pricing — shifts in demand, mix effects, and measurement quirks all distort the picture.
  • The findings have direct policy implications: misdiagnosing inflation's source risks misdirecting monetary and competition responses.
