Media plays role in igniting price wars
Before Reserve Bank Governor Graeme Wheeler even announced last week’s cut to the Official Cash Rate, there were media
reports of fixed mortgage rates heading towards record lows.
Massey University’s Professor Harald van Heerde, who has spent years studying price wars, says the impact of media

boxers, it really creates a sense of conflict, which makes for a better story. The tone and volume of coverage can start

Professor van Heerde says his research shows a significant “media effect”, especially if coverage of the price cuts is
“Using complex modelling we really teased out when companies responded to their competitors’ activity and when they were
