This paper focuses on the constant-utility price index in Japan based
on economic theory. Our empirical observation confirms the theoretical
foundation for our intuition that Japan endures wealth without prospe
rity partly because of expensive consumer goods and services. Japanese
consumers purchase commodities and services at prices more than 30 pe
rcent higher than in the US, the UK, France and Germany. To reduce the
price gap between domestic and international markets, deregulation of
domestic markets is necessary. (C) 1998 Elsevier Science B.V.
