A glimpse of the United States’ future?
The classic explanation of the evils of deflation is that it makes individuals and businesses less willing to use money, because the rational way to act when prices are falling is to hold onto cash, which gains in value. But in Japan, nearly a generation of deflation has had a much deeper effect, subconsciously coloring how the Japanese view the world. It has bred a deep pessimism about the future and a fear of taking risks that make people instinctively reluctant to spend or invest, driving down demand – and prices – even further.
