Quote from Ivanovich:
As someone who works in the consumer goods/staples industry, and who is involved in price setting, I can tell you that the reason many CPG companies aren't lowering their prices has nothing to do with conspiracy. It is more based on the belief that these lower prices will not be here to stay, and it is expensive and a long process for us to change our pricing structure - not to mention brand strategies that first have to be understood (in relation to competition).
Incidently, food prices showed a 1.5% drop in the latest reading - the best since 2006.
