Earlier quoted context omitted.
> Deflation tells consumers not to buy as you wait 6 months and it'll be cheaper. I live in Japan for many years and I have never seen such thing as deflation here. Prices have remained stable for most items or have increased a little bit. The idea that stuff becomes cheaper as you wait is ludicrous in Japan.
No serious economist believes the old wives tale about deflation keeping consumers on the sidelines while they wait to save 1 cent (or yen) on a can of soda next year. But it's got "truthiness" so it keeps getting brought up in these HN discussions.
A serious economist is able to differentiate between goods that can (and will) be delayed an a consumable like a can of soda. Cars are an example of a consumer good where consumption observably is affected by deflation.
